Tensile Strength Testing of Textiles "Tensile Machine Manufacturer Knowledge Sharing

Tensile testing of textiles provides strength and elongation properties for natural and man-made materials such as cotton, carbon, polyester, nylon, glass and graphite. Textiles can be tensile tested in many forms, including single strands, yarns, webbing, woven and braided materials, and nonwovens. Most textile fabric tensile tests are performed as grip tests in an effort to eliminate edge effects, or as strip tests that include edge effects. For grip testing, the fixture uses jaws smaller than the width of the sample to hold the fabric sample in the center. For the strip test, the fixture clamps a fabric using jaws wider than the sample width. For both tests, the sample is clamped inside the end of the sample length. Machines used for textile tensile testing are typically low force, high elongation, constant elongation or load, tabletop systems. Although the test machine seems to be the most important factor in testing flexible materials, fixture and jig movement must be considered....

Détecteur de données d'instrument d'éclatement de tissu textile HT

There are three main test methods for bursting strength or bursting strength: bursting method, marble bursting method and steel ball method. Foreign countries such as the United States, Japan, South Korea, Canada, Australia, etc. use the burst method to test. my country's GB/T 7742.1-2005 "Breaking Properties of Textile Fabrics Part 1: Determination of Burst Strength and Burst Expansion Hydraulic Method" refers to the burst test method in the international standard ISO 13938-1:1999. The test principle is: clamp the sample on the extensible diaphragm, apply liquid pressure under the diaphragm, and increase the liquid volume at a constant speed, so that the diaphragm and the sample expand until the sample ruptures, and the bursting strength is measured. This method can also test the burst expansion of the sample. Before the revision of the national standard "cotton knitted underwear", the burst strength was tested by the marble burst method, that is, a 25 mm circu...

What is the impact of the mask fixed way on the breathing resistance test?

What is the impact of the mask fixed way on the breathing resistance test? Generally speaking, the mask is a 3-layer structure, which is spunbond nonwoven(s) + meltblown nonwoven(M) + spunbond nonwoven(S), i.e. SMS structure. The outer layer is spunbond nonwoven with water-blocking effect, which can prevent droplets from entering the mask; the inner layer is nonwoven with softer material, which has moisture-absorbing effect and can discharge moisture from the mouth. The main part of the filtering effect is the middle layer of extremely fine and electrostatic meltblown nonwoven, the main material is high melt finger polypropylene, after electrostatic standing polarity treatment to achieve the standard required filtration efficiency. The influence of the mask fixation method on the breathing resistance test In GB/T 32610-2016 "technical specification of daily protective masks" in the inspiratory resistance, expiratory resistance test method, the mask in the test should be adjus...

Non-Destructive Testing for the Textile Industry

Non-destructive testing (NDT) methods include a wide range of analytical techniques to evaluate a variety of materials, elements, welds, systems, etc., without causing any damage or harm to the sample. This article focuses on the different NDT methods used in the textile industry. Textile testing instruments manufacturers use a variety of NDT methods for toxicological and other analytical tests to analyze their products for harmful substances such as allergens, heavy metals and even carcinogens. Several toxic metals such as cadmium, antimony, lead, chromium, mercury and zinc are either present in natural textile fibers, leached during the dyeing process or present in protective agents used to store textiles. Vibrational spectroscopy has been a commonly used method for nondestructive testing of textiles because when light interacts with molecules on the textile surface, it produces vibrations specific to the functional groups or chemical bonds present in the material. These vibrations ...

Textile testing equipment manufacturer-Qinyu: Sales of cotton fabrics in China have declined, and local marketing is still flat

In China's textile testing equipment manufacturing market, due to the Mid-Autumn Festival holiday, some merchants from north and south are returning to their hometowns and leaving the market day by day. The transaction of pure cotton fabrics in the traditional market has decreased month-on-month, and the transaction of most varieties of thin cotton fabrics in summer has declined. Transactions fell day by day. However, in autumn, the transaction varieties of medium-thick pure cotton fabrics increased, the domestic demand market was relatively active in placing orders, and the orders from target customers increased slightly. During the Mid-Autumn Festival, the sales of pure cotton fabrics declined, and some sales were still flat. As far as the overall market is concerned, the marketing of pure cotton fabrics is clearly differentiated, and some cloth companies and large-scale operating stores occasionally undertake small and medium-sized orders. However, due to the weak internationa...

The Biggest Problem With Martindale abrasion test standards, And How You Can Fix It

The Summary of Martindale Method for Testing the Abrasion Resistance of Fabrics The abrasion resistance of textiles refers to the wear resistance between fabrics or between fabrics and other substances during repeated friction. There are various methods for testing the abrasion resistance of textiles, such as the flat abrasion method, the curved abrasion method, the folded edge abrasion method and the compound abrasion method. The Martindale method is one of the flat abrasion methods and is widely used for testing the abrasion resistance of clothing and household textiles, decorative fabrics and furniture. ★ 5 forms of fabric wear damage In actual use, due to the different conditions of wear (e.g. force, size, abrasives, etc.), the structure of yarns and fabrics and the nature of the fibers are different, thus the mechanism of wear damage is different, with the following forms of damage. 1 During friction the fibres constantly collide with each other and fibre fragments brea...
