Tensile Testing of Textile Materials

Tensile Testing of Textile Materials
 
Tensile testing of textiles provides the strength and elongation properties for both natural and manmade materials, such as cotton, carbon, polyester, nylon, glass and graphite. Textiles can be tensile tested in many forms, including single strands, yarns, webbing, woven, braided material and nonwoven fabrics. The majority of textile fabric tensile testing is performed as either a grab test, in an effort to eliminate edge effects, or a strip test, including edge effects. For a grab test, the grips clamp a fabric sample in the center using jaws smaller than the sample width. For a strip test, the grips clamp a strip of fabric using jaws wider than the sample width. For both tests, grip the specimen inside the ends of the sample length. Machines for textile tensile testing are typically low force, high elongation, constant rate of elongation or load and are table-top systems. Although the testing machine may seem like the most important factor for testing with flexible materials, it is essential to consider the movement of grips and clamping fixtures. When testing webbing or fabric-type products, it is important to have free rotation at one of the grip mounts to ensure the grips are in the plane of the textile during the test. Test grips and fixtures must be determined by the specific type of textile being tested and, if the material is tested to a testing standard, the grip requirements will be described in the standard. ASTM and ISO specify test methods and requirements for the testing of textile materials. Due to the wide variety of textile materials, a single tensile test method would not be able to address all the variations needed to properly test different textiles. Popular ASTM tensile testing standards for textiles are ASTM D751 for coated fabrics, ASTM D1683 for woven fabric seam failure, ASTM D4964 for elongation of elastic fabrics, ASTM D5034 for breaking strength of textile fabrics, ASTM D5035 for breaking force of textile fabrics, ASTM D6775 for breaking strength of webbing and braided materials, and ASTM D7269 for testing aramid or nylon yarns. ASTM D76 specifies the requirements of the most widely used textile tensile test machines, including constant rate of extension (CRE) and constant rate of force or loading (CRL) machines.

Quality: Quality is the attribute of the products that determines its fitness for use, or according to Japanese Standard (JIS), textile (fibre, polymer, yarn, fabric) quality is all specific properties and performance of a textile product or service that can be evaluated to determine whether a product or services satisfactorily meets the purposes of its uses.
Modern Fibre or Polymer Quality Testing Equipment:
Fibre characteristics must be classified according to a certain sequence of importance with respect to the end product and the spinning process. Moreover, such quantified characteristics must also be assessed with reference to the following
• What is the ideal value?
• What amount of variation is acceptable in the bale material?
• What amount of variation is acceptable in the final blend?
 
Textile fibre contains some basic characteristics. 
Following are the basic characteristics of cotton fibre
• Fiber length

Technical Tests for Fiber Identification
 
Fiber Analysis: Qualitative
Scope: Describe physical, chemical, and microscopical techniques for identifying fibers in raw form or taken from yarn or fabrics.

• Fiber specimens are subjected to a variety of selected tests to determine generic class or specific type
• Visual and microscopical examination
• Burning test
• Solubility
• Stain Tests

 
Technical Tests for Fiber Identification

There are two types of methods that are used for identifying different fibers - the nontechnical tests and the technical tests. The nontechnical tests include the feeling test and the burn test. The technical tests include microscope test and chemical test. The technical tests for fiber identification are carried out in laboratories and require technical knowledge and skills. As such, they are much more reliable methods for testing end product as compared to the non technical tests.
 
Natural fibers have their own peculiar structures, spots, lines and other marks that help in identifying them. Following are some examples of natural fibers and how they look like under a microscope: 

Cotton: The cotton fiber is a single elongated cell. Under a microscope, it looks like flat, spirally twisted ribbonlike tube with rough granular surface. However, mercerized cotton doesn't have natural twist. The finishing process makes them swollen, straight, smooth and round with a shining surface.

Linen: Linen fiber, under a microscope, looks like having multiple sided cylindrical filaments with fine pointed edges. The filaments show nodes at intervals. It, in fact, looks like a bamboo stick having joints that results into a little unevenness.

Wool: Wool fiber has irregular, roughly cylindrical, multi cellular structure with tapered ends. Under a microscope, three basic layers are shown- epidermis (outer layer), cortex (middle layer) and medulla (inner layer). Medulla is seen only in coarse and medium wool fibers and that too under a highly powerful microscope. 

Silk: Raw silk fiber, composed of two filaments, has elliptical shape under the microscope. The two fine and lustrous filaments are shown clearly looking like transparent rods with triangular shape. Wild silk or tussah fiber has different appearance than the cultivated silk. It is flattened, coarse, thick and broader fiber having fine, wavy lines all across its surface whereas cultivated silk is narrower fiber with no marks on it.

Talking about Taber Abrasion Testing

Taber Abrasion is a quick and inexpensive procedure, designed to compare the wear rate and mass-loss of one or more material or coatings. A typical Taber abrasion test consists of a disk-shaped specimen that is placed in constant contact with an abrasive wheel, using predetermined forces to a specified number of cycles to determine wear. The most commonly used standards for these tests are: ASTM D4060, ASTM F1978-12 and MIL-A-8625.Qinsunlab  frequently recommends Taber abrasion as a quick and simple way to measure wear resistance and offer sufficient comparable data at a reasonable price. It gives a side by side comparison of several materials or coatings, so you can evaluate which material has better wear resistance under simulated, accelerated wear conditions.

The measurement of abrasion resistance, usually by the weighing of a material sample before and after subjecting it to aknown abrasive stress throughout a known time period, or by reflectance or surface finish comparisons, or by dimensional comparisons.

An abrasion test is a test used to measure the resistance of a material to wear stemming from sliding contact such as rubbing, grinding, or scraping against another material. An abrasion test may also be referred to as wear testing, as an abrasion resistance test, or simply as a resistance test. Wear testing is of interest in a number of technical fields, including civil and mechanical engineering, reliability engineering, metallurgy, and geology. These tests are of importance in ensuring the durability of a material in a particular product or application, and in ensuring that material that erodes because of abrasion does not cause environmental or safety hazards in the production or test environments or in use of the product.

Several factors are typically considered in developing or selecting an appropriate abrasion test for the application at hand. The shape of the contact area is taken into consideration, as is the composition of the two surfaces making contact with one another. Speed of sliding contact between the two surfaces, the force with which they act on one another, and the duration of contact between them may also be considered. In addition to the materials themselves, the environment in which they are making contact also plays a role in selecting an appropriate abrasion test.

Textile Abrasion Test

Textile AbrasionTest: Wyzenbeek vs Martindale

Martindale vs. Wyzeenbeek-Explained. 

Fabric Abrasion Tester is Suitable for woven, knitted, woven, decorative materials, coated fabrics and other apparent abrasion resistance testing and pilling performance test.

Both Wyzenbeek and Martindale are abrasion tests; which test different properties of a textile. Wyzenbeek involves rubbing along the warp and weft of the fabric whereas Martindale is a figure-8 rub. Success in one test does not infer success in the other.

The Wyzenbeek and Martindale tests are the two methods commonly used to predict wear-ability. Actual performance is determined by many factors such as fiber content, weaves, finishes, furniture design, maintenance, cleaning, and usage. Durability of an upholstery fabric is a complex interaction (combination) of a number of performance tests that, in addition to abrasion, includes seam slippage, piling, tensile strength, and usage.

“ Addressing the excessively large, sometimes phantom, Wyzenbeek wear numbers currently in the industry… ‘we test to either measure failure or to confirm success. We test to convey, not to impress.’ ”

What happens…

A Wyzenbeek machine is used for this test allowing sample of the test fabric to be pulled tight in a frame and help stationary. Individual test specimens cut from the warp and weft direction are then rubbed back and forth using an approved fabric as the abradant. The number of double rub cycles achieved before two yarn breaks occur or noticeable wear is observed is recorded as the fabric’s abrasion rating.

Martindale uses an oscillating test. Fabric samples are mounted flat and rubbed in a figure eight like motion using a piece of worsted wool cloth as the abradant. The number of cycles that the fabric can endure before fabric shows objectionable change in appearance (yarn breaks, piling, and holes) is counted. Number of cycles determines abrasion rating.

Abrasion levels are often over specified in the faulty assumption that abrasion tests predict a product’s overall durability and life span. A recent industry survey indicated that for many end-use applications, factors other than surface abrasion are more likely to result in fabric failure and therefore should be considered when evaluating product durability.

Considerations before Specifying

Abrasion resistance is only one component of durability. Considering this in combination with other factors will enable you to choose the most suitable fabrics for your project.

Always consult with your supplier to confirm that the fabric you are considering should perform well in the onsite environment.

Review the results of the other ACT recommended physical property tests for durability. Abrasion results alone do not predict a product’s lifespan.

Consider the style and quality of the furniture the specified fabric will be used on; seat pans with a waterfall edge and upholstered arms of a chair are common areas of wear. Is there adequate padding to support the upholstery?

Take into account the amount of traffic in the environment and the wear the fabric is likely to receive. Keep in mind, the ACT recommended physical tests for durability do not indicate how a product will perform in an abusive environment. • Determine whether or not the fabric will receive regular professional cleaning. Dirt is the enemy of fabric, but improper cleaning will also shorten the durability/lifespan of the product.

Evaluate whether or not the end use requires a fabric treatment. Applying treatments, finishes or backings to a fabric may enhance durability, but may also negatively affect flammability resistance, appearance or environmental properties.

Taber Linear Scratch Testing with Reciprocating Abraser

Taber Linear Scratch Testing with Reciprocating Abraser

The Taber Reciprocating Abraser includes a counterbalanced arm which pivots on an adjustable height gantry system. The counterweight allows the user to balance the test arm, ensuring precise test load set-up regardless of the weight of the attachment. Incorporated at the end of the arm is a tool holder to which optional attachments and weights may be secured. A sliding specimen platform moves in a horizontal, reciprocating motion under the stationary tool holder.

Reciprocating abrasion tester used by way of rotary grinding, using different kinds of friction wheel rotational friction on the sample to detect wear performance for leather and plastic materials, make scientific evaluation of the wear resistance on the product.

Depending on the type of material under evaluation, the visual appearance of a scratch or mar normally involves changes in surface topography, color, or brightness.  Three methods are normally used:

Visual Evaluation - Scratch resistance is normally reported as the minimum load necessary to penetrate the surface of the specimen. The observer increases (decreases) the testing load until the point when a visible line is scratched on the specimen surface. This line should penetrate the surface and not be able to be wiped off.  It is also possible to rank scratches based on an existing standard. A standard numeric rating representing 3 to 5 increasing scratches (or what constitutes a Pass / Fail) may be established for each type of material and used solely for comparison to determine test end point.

Test products are fixed at the level of the table, in the abrasives and load with the movement of the provisions under the level of water for the station being worn; The use of the principle of leverage, the other end of the arm with the test weight to maintain balance test arm to ensure the reliability and accuracy of the sample surface load test results.

Abrasives and load frame height is adjustable to be suit for different height of the sample tested. According to the different requirements of customers, the use of different media to test different products friction abrasion resistance.

Deep Abrasion Resistance

DEEP ABRASION RESISTANCE

Method only applicable to unglazed ceramic tiles. The testing method and the expression of results are the same as those indicated in the previous European Standards (EN 102). Only one modification has been made regarding the material to be used for the calibration of the instrument. The calibration procedure remains unchanged. For unglazed tiles the Capon test is executed by adding sand or another scratching material between the tile and the machine.
The scratch resistance of the surface is also known as the Mohs value. This has not been taken into account in the current norms but is still important in today’s market. The Mohs hardness is determined by observing whether its surface is scratched by a substance of defined hardness.By making scratches in the surface of the tile with different minerals as chalk(1) or diamond (10) the Mohs value is determined. Glazed tiles should have a Mohsvalue  of min.5 and unglazed tiles a value of at least 6.

Abrasion resistance is the capacity of the surface to resist to the wear caused by foot traffic or by mechanical equipment . The wear action is strictly linked to the material carried on to the surface (water, sand, mud, etc.) and classified in five categories depending on the areas they are used in:

For glazed tiles the PEI test is used to see how  the surface reacts to the circular movements made by the machine.

Yarn on Yarn Abrasion Resistance

Depending on the nature of the working environment, the abrasive wear of concrete floor slabs can range from scratching or scuffing to impact and local crushing. To assess abrasion resistance it is, therefore, necessary to have a versatile apparatus.

Abrasion & Wear  Testing. When abrasion is the predominant factor causing deterioration of your materials, testing will give you data to compare materials or coatings and can help you predict the life time of a material or coating. Abrasion testing is used to test the abrasive resistance of solid materials.

Interyarn abrasion has been determined to be a principal cause of failure and of short service life of large synthetic fibre ropes during tension and bend cycling. The YoY abrasion test is used to determine the quality of finish applied on yarns to enhance abrasion resistance, especially in wet conditions. It is also used to compare the relative abrasion resistance of various yarns.

The test measures abrasion cycles to failure on interwrapped yarn at various applied tensions. The yarn is interwrapped in contact with itself between three pulleys, as shown in Figure 1. For wet testing the interwrapped yarn is immersed in water. The yarn is then drawn back and forth under tension until it fails. A number of tests are conducted at each of several applied tensions.

The abrasion test is now described in ASTM D-6611, “Standard Test Method for Wet and Dry Yarn-on-Yarn Abrasion Resistance” and in Cordage Institute (CI) 1503 “Test Method for Yarn-on-Yarn Abrasion, Wet and Dry”. It is the basis for CI 2009P “Performance Requirements for Marine Grade Polyester Yarn for Fiber Rope”.

Standard Test Method for Abrasion Resistance

There are different test methods to determine the abrasion resistance of concrete subjected to number of various types of abrasion. There are number of different tests used in various countries and it is clear that there is no single test that adequately measures the abrasion resistance of concrete under all conditions. This paper covers the summary and classification of the various abrasion tests which are listed below.

This test method covers three procedures for determining the relative abrasion resistance of horizontal concrete surfaces. The procedures differ in the type and degree of abrasive force they impart, and are intended for use in determining variations in surface properties of concrete affected by mixture proportions, finishing, and surface treatment. They are not intended to provide a quantitative measurement of the length of service that may be expected from a specific surface.

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of each other.

This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

When abrasion is the predominant factor causing deterioration of your materials, testing will give you data to compare materials or coatings and can help you predict the life time of a material or coating.

Abrasion testing is used to test the abrasive resistance of solid materials. Materials such as metals, composites, ceramics, and thick (weld overlays and thermal spray) coatings can be tested with this method. The intent of this test method is to produce data that will reproducibly rank materials in their resistance to scratching abrasion under a specified set of conditions.

The test should not be used to predict the exact resistance of a given material in a specific environment. Its value lies in predicting the ranking of materials in a similar relative order of merit as would occur in an abrasive environment. Volume loss data obtained from test materials whose lives are unknown in a specific abrasive environment may, however, be compared with test data obtained from a material whose life is known in the same environment. The comparison will provide a general indication of the worth of the unknown materials if abrasion is the predominant factor causing deterioration of the materials.

QINSUN Textile Testing Instruments

There are mainly two types of testing, one is routine process testing and another is quality record testing. The result of routine process testing can be got quickly in the working field. The result of quality record testing is to be recorded for different objects to finish the work.

Textile Testing

Textile Testing is an important part for textile production, distribution, and consumption. We can also define Textile Testing as the process of determining the properties of different kinds of Textile substances.
 

Objectives of Textile Testing

The objectives of Textile Testing are as follows –

• In case of research, the results of testing will help the scientist to decide which route should be followed.
• It helps to select the proper raw materials. Raw material is a relative term. As for example, fibre is the raw material of spinner, yarn is the raw material of weaver etc.
• Textile Testing helps to control the different processes. Such as Spinning, Weaving, Dyeing, Finishing etc. End breakage is controlled by controlling weight per lap length, sliver length and roving length. Weaving process is controlled by controlling the excessive breakage of warp and weft yarn. Dyeing process is controlled by M : L, temperature and pressure.
• In case of product control, it helps to ensure the fulfillment of the desired quality of the end product. Such as the end product of spinning is yarn.
• In case of process development, it helps to improve the quality of end product by avoiding unnecessary waste of time and money.
• In case of product development, it helps in continual search for new knowledge and to develop new products.

Factors affecting Test result

• Atmospheric conditions
• Test methods
• Testing instruments
• Technician’s efficiency etc.

Different types of Textile Testing

Fiber Tests

Fiber tests include identification of fibers, grading, fiber length, strength and elongation, fineness, maturity etc.

Yarn Tests

Yarns tests include yarn count, twist per unit length, strength, appearance, evenness and regularity, hairiness etc.

Fabric Tests

Fabric tests include strength and elongation, width, thickness, number of ends and picks per unit length, the count of yarn used, fabric weight per unit length, design and construction of the cloth, air permeability, thermal properties, stiffness, handle, drape, crease resistance and recovery, abrasion, pilling, shrinkage etc.
