Importantance Of Yarn Twist Test

Twist has a critical effect on the physical properties of yarn such as softness, tensile strength and cover factor.  Optimum twist level is important for both yarn end-users and production plants.Determining optimum twist can have a critical effect on the physical characteristics of yarns. Yarns with a low twist count are capable or producing a yarn with increased softness for knitting and warmth.Increasing twist count can provide additional tensile strength. However, maximum tensile strength can decrease if the twist angle is greater than the desired amount.




The Yarn Twist Tester provides semi-Automatic testing of single or plied yarns. Digital displays of twist for sample length tested, as well as twist per unit selected (twist per inch, twist per centimeter). Automatically stops at end of test. Allows multiple test of same sample. Variable speed. Specify 110 or 220 volts, 50/60 Hz.



Electronic Twist Tester meets applicable standards for measuring twist in the yarn.  The machine is designed to apply Untwist-Retwist Method, Direct Counting Method and Schutz Method, which is special mode for Open-End yarns.
The instrument is a motorized unit with two clamps. One clamp is on adjustable stand to select yarn test length while the other clamp rotates in S or Z direction for twist removal.

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...
