Principle Analysis and Solution of Pilling

Fabric in the processing and taking the process, when subjected to external friction, such as friction is greater than the fiber strength or friction between the fibers or cohesion, the fiber ends will be pulled out to form a ring and fluff, the fabric surface to produce fluff So that the fabric lost luster. When the villi exposed to a certain length, the villi in a certain distance due to rubbing friction, repeated elongation and retraction and entangled into a ball, seriously affecting the appearance of the fabric surface.

When the fabric surface of the pompon formation, due to the different fiber breaking strength, yarn twist, fabric structure and so on, some pompon after the formation of easy to fall off, and some easy to fall off, entanglement, and easy to filth , Affecting the quality of clothing taking.

Cashmere fiber fine fineness, low strength, poor spinnability; Soybean protein fiber monofilament fine fineness, light weight, high strength, and acid and alkali resistance, moisture moisture permeability is good, with a soft feel of cashmere, silky soft luster, was As "artificial cashmere".
Soybean protein fiber and cashmere blended products have a good moisture permeability and antibacterial health care function, and showing a silky glossy, velvety feel. However, in the processing, wearing and washing process, due to the fabric and the fabric and other objects can easily produce pilling between the phenomenon of pilling, the fabric appearance significantly worse. So, how does the mechanism of soy protein fiber and cashmere fiber pilling up?


For the cashmere, soy protein fiber blended fabric, the soybean protein fiber has good strength, in the pilling and chemical fiber similar, thus exacerbating the pilling phenomenon of the fabric.
For the spinning weaving, wool fabric pilling performance should be the most important one, then, how can we effectively improve it? Here to introduce the two types of items from the pilling tester solution.1. Improve the spinning weaving process:
   
Yarn with air-jet anti-pilling effect is better than ring spinning. Ring spinning, longer fibers tend to concentrate in the middle of the yarn, while the shorter ones are on the outside, resulting in pilling.
   
In the process before combing, the cotton or sliver is fully combed to reduce the impurities and neps in cotton or sliver by controlling the yarn count, yarn twist, changing the fabric structure, improving the tightness, etc. Improve the fabric's anti-pilling performance, have a certain effect, but the fabric feel, appearance, etc. will be affected. Ring yarn cotton fabric singeing2. Polished:
   
Bio-polishing is a finishing process used to improve the surface of cotton fabrics with cellulase to achieve lasting anti-pilling and increase the finish and softness of the fabric. Bio-polishing is to remove fine fibers that extend from the surface of the yarn.
   
The hydrolysis of the enzyme and the mechanical impact of the common removal of the fabric surface of the plush and the end of the fiber, the fabric becomes clearer, more bright color, the use of bio-polishing to reduce the fabric pilling trend of lasting effect.3. Resin finishing:For cotton fabric pilling resistance, can be mainly used bio-polishing, and sometimes can be combined with singeing and resin finishing, but the singeing is not durable, focusing on governance table, resin finishing will affect the fabric feel.

Multi-Functional Scratch tester For automotive interior materials

          Multi-Functional Scratch tester is applicable to all types of wiping performance test of automotive interior materials; test equipment integrated three domestic standards (fingers scraping method, a hundred grid method, and plastic scraping finger scraping method).         Scratch tester is an electronic instrument capable of measuring critical load, adhesion, scratch resistance and bond strength for a wide range of surfaces. Scratch tester measures the scratch resistance of a sliding and moving surface in the relative motion to a stylus. The stylus is forced/pressed against the moving surface with precise controlled force which is normal to the surface and tangential force at the contact has to be measured.         Scratch tester can be utilized for all type of industrial coating from the plasma layers used in semiconductor and optical technology used in decorative coatings used for automotive and consum...

Reveal the standards for textile breathability testing and let you understand it in seconds!

 Reveal the standards for textile breathability testing and let you understand it in seconds! Breathability testing is a measure of how much gas can pass through a textile. However, there is no single "optimal" air permeability value, as it depends on the specific circumstances in which the textile is used. For example, if it is used to make sportswear, it is hoped that it has good breathability; if it is used to make insulating clothes or warm clothes, it is hoped that it can block the cold well. Therefore, when testing the air permeability of textiles, the purpose of using the textile must be clearly understood in order to obtain reasonable values. In order to accurately and quickly test the true breathability performance of a sample, specially designed and developed instruments must be used. Testing methods generally include: fabric thickness (Thickness), fabric density (Density), fabric water absorption rate (Water Absorption Rate), evaporation and mass transfer (Moistur...

Test Methods of Universal Pilling Assessment Viewer (PAV)

Universal Pilling Assessment Viewer enables fabric to be assessed while still mounted on a Martindale head. The Pilling Assessment Viewer (PAV) for the textile market has been developed with the help of a major textile company in accordance to BN EN ISO 12945 standards incorporating all 3 parts and adopting the following test methods: Part 1: ICI Pilling box method (BS 5811) Part 2: Modified Martindale method (SN 198 525) Part 3: Atlas random tumble method (ASTM D 3512-96) It uses D65 Artificial Daylight (with CWF optionally available), as specified by many retailers. Other test methods can also be viewed, including those specified by major retailers. Other results of test methods that can be viewed include: BS 5811:1986 Determination of resistance to pilling and change of appearance of fabrics. ICI modified pill box for snagging Fleece appearance and surface change after washing Other test methods as specified by several major retail outlet. To optimize c...
