Testile Testing Equipment

Product features tend to change over time, the visual appearance is often the consumer to judge the quality of life during the product quality is good or bad. Thus, durability and wear resistance during normal use affect the overall impression of product quality. Damaged surfaces are some of the main causes of poor quality. So in the production of wear testing required, and then an effective evaluation of the product can effectively meet the requirements of consumers, to consumers the feeling of high-quality products. Finger wear test At present, many instruments exist, such as the electronic button wear test, the current use of more RCA tape wear instrument, the same universal finger wear tester can also be used to measure the electronic button wear test. Below to interpret the universal finger wear tester : Universal finger wear tester: The finger on the surface slides to produce the highest biomechanical feedback when the object interacts with the object. When touching th...

Shoes with leather friction fastness method summarized into three kinds of reciprocating wool felt friction leather; reciprocating white lining cloth friction leather; fixed point rotating wool felt friction leather. Rotary wool felt friction method is with the diversification of shoe design, multi-block splicing shoes more and more, in the shoes can not get enough long sample, and to detect the end-use of shoes adaptability, Taken by. However, the results of the friction test of rotary and reciprocating wool felt are not consistent and the method to be used in the Leather Color Fastness test results.  Reciprocating wool felt rubbing the leather method to maintain the continuity of quality control, so that the raw material leather to make shoes leather using a relatively consistent test method, the results are comparable. Currently using more. Dry wipe: the use of the sample face up, into the sample folder should be stretched, not wrinkle. The specimen holder is cla...

Vacuum method is the most representative of the differential method of a test method. The test principle is to use the sample to separate the permeate chamber into two separate spaces. First, both sides of the sample are evacuated and then filled to one side (A high pressure side) Absolute pressure) of the test gas, while the other side (B low side) is to maintain a vacuum state, the sample on both sides of the formation of 0.1MPa test gas pressure. The gas permeation of the test gas enters the low pressure side through the film and causes a change in the pressure on the low pressure side. The amount of gas permeation (GTR) of the test gas can be calculated using the formula by measuring the amount of pressure on the low pressure side with a high precision vacuum gauge. The relevant standards are ISO 2556, ISO 15105-1, ASTM D 1434 (M method), GB 1038, JIS K 7126 (A method) and the like.  The gas permeation (GTR) provided by ISO 15105-1 is calculated as follows: Where: ...

abrasion resistance is one of the important performance of denim clothing, but also the production enterprises and consumers are mainly concerned about the indicators.  Poor wear resistance of clothing, easy to wear after wearing, affecting the use of the product cycle. At present, FZ / T81006-2007 "denim clothing" standard for the detection of wear resistance is mainly used GB / T 21196.2-2007 "Textile Martindale fabric abrasion resistance of the second part: the determination of sample damage"  The principle is to cut a representative sample on the denim clothing, placed on the  Martindale wear tester , in the specified load and speed, the trajectory for the Lissajous (Lissajous) graphics plane motion and abrasive  Friction, the specimen holder can be free to rotate about the center axis perpendicular to the horizontal plane. Two or more non-adjacent yarns were completely broken, the test was terminated, and the  abrasion resistance  of the ...

In recent years, due to the destruction of the ozone layer, reaching the surface of the radiation is increasing, excessive ultraviolet light on the human eye, skin and immune system caused some damage, so the anti-ultraviolet light of textile increasingly attention. The market has more and more anti-UV products, the performance of the pros and cons, a direct impact on the interests of consumers. When ultraviolet rays are irradiated onto the fabric, a portion is absorbed, a portion of the fibers that penetrate the fabric (including from the voids of the fabric), and a portion of which is reflected. Through the fabric of the more ultraviolet, the greater the harm caused by the human body. Therefore, the main way to improve the performance of UV protection is to enhance the fabric of ultraviolet absorption and reflection ability, thereby reducing its throughput, usually there are three ways: 1) coating on the surface of the fabric; 2) blended in the fabric into the anti-UV addit...

What is the Geosynthetics vertical osmometer, how to operate? This article will be one by one for you to resolve   the test instrument.first：Geosynthetics vertical osmometer Applicable to all kinds of geotechnical materials vertical permeability test. main steps: 1, the sample placed in water containing humectant, soak for at least 12h until saturated and remove the bubbles, wetting agent with 0.1% V / V sodium alkyl benzene sulfide. 2, remove the high pressure warehouse, the installation of the specimen in the holder, the sample requirements: the sample should be clean, no dirt on the surface, no visible dirt or crease, shall not be folded, and should be placed in the flat, the above shall not be imposed Any load. And then install the high pressure warehouse, followed by the balance of force to tighten the high pressure warehouse nut. 3, open the water valve, into the clean water to the high pressure water tank until the water level on both sides of 50mm head ...
