The process to determine the properties of different kinds of substance is called testing. Testing is an important segment of the textile industry. We can easily detect the faults of machinery and materials during test of textiles. Besides, textile testing needs to assure compliance with changing governmental safety regulations and to meet increasing consumer demand for high-quality textiles and apparel. If testing lab has adequate testing equipments then can be possible to proper test.

Textile testing allows companies, consumer groups and the government to make sure textiles are safe, of good quality, and that the customer is getting what they are paying for. Textile products are made around the world, and sent to markets around the world. Testing ensures that something harmful or illegal isn’t slipping through the regulatory cracks. In this article I will discuss different types of textile testing equipments used in textile industry.

Fiber Testing:

USTER ZWEIGLE friction tester 5:
In textile industries, friction has an important role to play and everywhere friction can be seen. Fibre-to-fibre friction, spinning friction, winding, weaving and knitting between yarn and yarn guidelines. Yarn friction is significant in relation to the yarn’s running behavior.

USTER ZWEIGLE friction tester 5
Fig: USTER ZWEIGLE friction tester 5

Feature of the machine:
The crucial aspect of the USTER ® ZWEIGLE FRICTION TESTER 5 is its two-wheel beam and sensor design. It allows for immediate adjustment of differences in tension in the yarn box. A ZERO force area is created between two rollers during measurement. There is also a yarn tensioner.

Principle of this machine:
The theory of this unit is that the yarn is pushed horizontally by the disk tensioner according to its power. Across both plates the yarn moves. The upper disk is constantly forced to generate a given strength on the yarn. The powers F1 and F2 are able to determine the coefficient of friction. It is the friction between fabric and metal. The yarn is moved in one direction at 200 meters a minute and in a different direction. Both rollers are very sensitive and each small lateral movement can be detected individually in both directions. Since the force F1 applied on the yarn is known and the force F2 is measured & the yarn friction can be calculated.

Fabric Testing:

Textile fabrics are manufactured for several different end uses, each of which has different performance requirements. The chemical and physical structures of textile fabric determine how it’ll perform, and ultimately whether it’s acceptable for a specific use. Fabric testing plays an important role in gauging product quality, assuring regulatory compliance and assessing the performance of textile materials. It provides information about the physical or structural properties and therefore the performance properties of the fabrics.

Fabric characteristics:

  • Identification of fabric weight
  • Resistance of fabric to friction
  • Rubbing fastness on fabric color
  • Water repellency of fabric
  • Color fastness to sweat
  • Color fastness to light
  • Creases resistance of fabric
  • Fabric strength

  • Maintain the weight of the tissue in the electric balance machine after completely cutting the tissue.

Pilling tester:
Abrasion resistance is referred to as resistance to friction of cloth. Pilling is a fabric defect that can be seen as a small ball of fiber or group of fibers that are secured by one or more fibers on the surface of the fabric. During wear and washing the pills are made, which means that the friction forces influence the materials during use. Abrasion and pilling of fabric results from the friction forces.
