Terms of Textile Properties and Testing: abrasion, fuzzing, pilling…

The performance and testing of materials are fundamental pillars in the development of the textile industry. From fiber selection to the final formation of fabrics, every step requires precise control over material properties and rigorous testing validation. With the rapid advancement of textile technology, new materials and processes continually emerge, leading to updates in performance indicators and testing methods.

The scope of textile material performance and testing has expanded significantly, encompassing both traditional natural fibers and modern high-performance synthetic fibers, as well as a wide range of physical and chemical testing methods. However, these terms are often highly specialized and complex, making them challenging for industry newcomers, students, and general readers interested in textiles to understand.

This article provides a systematic and comprehensive explanation of textile material properties and testing terms in an accessible manner. It covers various aspects such as fiber fineness and strength, fabric permeability and moisture absorption, and complex testing methods like tensile testing and abrasion resistance testing.

Abrasion Resistance

The ability of a material to withstand wear. It is typically measured by the number of friction cycles required to cause a certain degree of wear on a sample or by assessing changes in the sample’s appearance, strength, thickness, and weight after a specific number of friction cycles.

Martindale Abrasion Test Method System

Determination of Sample Breakage

Test Principle

A circular sample installed in the sample fixture of a Martindale abrasion tester undergoes planar motion with a Lissajous – shaped trajectory and rubs against the abrasive (i.e., standard fabric) under a specified load. The sample fixture can rotate freely around an axis perpendicular to the horizontal plane. The abrasion resistance of the fabric is determined based on the total number of friction cycles when the sample breaks.

Test Principle

A circular sample installed in the sample fixture of a Martindale abrasion tester moves in a planar motion with a Lissajous – shaped trajectory and rubs against the abrasive (i.e., standard fabric) under a specified load. The sample fixture with the abrasive can rotate freely around an axis perpendicular to the horizontal plane. The abrasion resistance of the fabric is determined based on the changes in the appearance of the sample.

Industry Application Cases

 

Apparel and Outdoor Clothing:
The determination of the number of breakage cycles is used to assess the durability of items likehard-shell jackets and ski suits in high – friction environments.

Automotive Interiors:
The appearance change evaluation is used to assess the appearance retention ability of seat fabrics.

Industrial Conveyor Belts:
A combination of the determination of the number of breakage cycles and the determination of mass loss tests is used to verify the performance stability of materials under long – term friction.

 

Factors Affecting the Abrasion Resistance of Fabrics

Characteristics of Fibers

Geometric Features

(1) Generally, the longer the fiber, the better the abrasion resistance.

(2) A moderate fiber fineness is beneficial for abrasion resistance. If the fiber is too fine, the stress is high. If it is too coarse, the number of fibers is small, the cohesion is weak, and the bending resistance is poor.

(3) In terms of cross – sectional shape, fabrics made of profiled fibers have worse flex abrasion resistance and edge – fold abrasion resistance compared to those made of circular fibers.

 

Mechanical Properties

Fabrics with high breaking elongation, high elastic recovery rate, and high breaking specific work generally have good abrasion resistance.

Structure of Yarns

  1. Twist
    The twist should be moderate. If the twist is too high, the mobility of fiber segments is small, the yarn is stiff, and the contact area is small. If the twist is too low, the yarn structure is loose, and fibers are likely to be pulled out.
  2. Fineness
    The coarser the yarn, the better the abrasion resistance, especially in flat abrasion.
  3. Yarn Evenness
    Yarns with good evenness are more abrasion – resistant. (The thick places are loose, and fibers are easy to be pulled out.)
  4. Single Yarn and Plied Yarn
    Fabrics made of plied yarns have better flat abrasion resistance than those made of single yarns, but they are worse in flex abrasion and edge – fold abrasion.
  5. Radial Distribution of Blended Yarns
    Fibers with good abrasion resistance are required to be distributed on the outer layer of the yarn.

yarn structure

Fabric Structure

  1. Weight per Square Meter
    The higher the weight per square meter, the better the abrasion resistance.
  2. Structure Phase and Support Surface
    Near the fifth structure phase, with a large support surface, the abrasion resistance is good.
  3. Fabric Density
    A moderate fabric density results in better abrasion resistance.
  4. Fabric Weave
    The fabric density and weave should be considered comprehensively. When the warp and weft densities are low, plain weave is more abrasion – resistant. When the warp and weft densities are high, satin weave is more abrasion – resistant.

Test Conditions

  1. The selected abrasive.
  2. Tension and pressure.
  3. Temperature and humidity in the test environment.
  4. The direction of friction, especially for satin – weave fabrics.

Post – Treatment

The abrasion resistance of cotton and viscose fabrics shows different results under different pressures during testing. For example, when the pressure is high, the abrasion resistance decreases, and when the pressure is low, the abrasion resistance increases.
