Comparison of Test Methods for Moisture Permeability

       Textile moisture permeability refers to the performance of sweat through the fabric, also known as permeable steam, is reflected in the body when the heat to maintain the body heat and heat dissipation of one of the indicators of heat balance. Moisture permeability: (G / m2.h) or grams per square meter of 24 hours (g / m2.h) per gram per square meter of water vapor per unit area of ​​the sample in the specified time under the condition of maintaining the specified temperature and humidity conditions on both sides of the sample, M2.24h). Moisture: (G / m2.Pa.h) per square meter per square meter of water vapor per unit area of ​​the sample, which is vertically passed through the unit water vapor pressure under the condition of the specified temperature and humidity conditions.  The GB, European standard, American standard, the Japanese standard has a moisture permeability test standards, these standards are tested moisture permeability index. From the method point

Seven Problems in Textile Enterprises

With the weakness of the world economy and the slowdown in China's economic growth, once the wind and fire industry, instantly facing the moment of life and death, yesterday's rapid growth and today's life and death seems to come too suddenly, but many textile companies have to face, Any industry or country will have a ceiling and slow growth stage, can only adapt to rapid growth and can not adapt to the slow pace of the enterprise will be eliminated. Standard Group has been concerned about the textile industry dynamics, after more than a decade of development, we witnessed the outbreak of the textile industry and in recent years, bleak, downtown industry competition where the competition? What are the problems faced by textile enterprises?        The textile industry is also accompanied by the rapid development of the textile industry. It is also accompanied by the stagnation of the growth of the textile industry . At present, many domestic textile equipment

What Is The Principle Of Scratch Resistance Testing ?

        Surface scratch resistance is the ability to detect the surface of the product decorative paper against a certain role under the diamond needle. Wipe the surface of the specimen, the measured surface up fixed on the scratch test bench. Adjust the height of the beam, so that the diamond tip contact with the specimen surface, the upper edge of the beam in a horizontal position. The weight moved to 1.5N position to start the stage rotation, so that the diamond needle in the specimen surface to draw two concentric circles, in the radial direction between the scratches and scratches the distance of l-2mm to remove the specimen , Observe the specimen was scratched parts of the situation.                ISO 12137-1: 1997 and ASTM D5178-98 Test principle: The test product is applied in a uniform thickness to a flat surface with uniform surface texture. After drying / curing, the scratch resistance is measured by pushing the test plate under the arc (ring or ring) needle,

How to use and maintain the Taber wear test machine

Wear-resistant testing machine mainly through the rotation of the grinding method, the use of different types of friction wheel rotation on the sample to detect leather and plastic materials, wear resistance. Widely used in metal, paint, sheet surface, coating materials, textiles, leather, rubber and other fields of performance testing. This article is for this widely used instrument, focusing on the use of operation and maintenance of some of the notes First, the principle Principle of the test: the test sample placed on a rotating platform, through the top of the two rolling friction wheel under a certain load and the specimen friction friction movement to wear samples. A friction wheel facing outward, another friction wheel inward friction specimen, forming a circular wear trace. After the specified number of times of friction, the degree of wear of the specimen is evaluated by appearance. Second, the operating instructions Test preparation: 1. Fix the test specimen on the test turn

UV Resistance Test Practice

anti-ultraviolet finishing agent HTUV100:Anti-UV finishing agent HTUV100 is manufactured by Herst International Group, which can be used for efficient and durable UV finishing of cotton, silk, wool, polyester, nylon and blended fabrics and to improve the fastness of some dyes. Clothing, beachwear, bath suits, casual clothes (T-shirts, shirts, hats, etc.), professional wear and tents, umbrellas, curtains and other UV shielding performance.
