What physical properties of textiles are tested by textile testing instruments?

Textile testing instruments is a kind of physical property testing instruments used in the field of textile science and technology,.

What physical data can textile testing instruments be used to test?

1、Hydrostatic pressure

Outdoor fabric industry is customarily called water pressure, the unit with mmH2o said, refers to the unit area to withstand water pressure strength, in standard laboratory conditions, the fabric to withstand the pressure of distilled water sprayed upward, and record the water pressure value, such as water pressure 5000mmH2o, that is, the unit area can withstand 5m pressure without leakage. Hydrostatic pressure tester is used to determine the water resistance of medical protective clothing, compact fabrics such as canvas, tarpaulin, thatch, tent cloth, rainproof clothing cloth and other materials.

2、Breathability

Air permeability means the performance of air through the fabric. Under the specified differential pressure condition, the air flow rate through the given area of the specimen vertically within a certain time is measured and the air permeability is calculated. The air flow rate can be measured directly, but also by measuring the flow aperture on both sides of the pressure car conversion and obtained. It is used to test the air permeability of materials such as nonwoven fabrics, protective clothing, meltblown fabrics, special industrial fabrics, general fabrics, sponges, knitted fabrics, coated fabrics, nonwovens and industrial filter paper.

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...
