High-density textile physical property detection method

Abstract

The invention relates to a textile physical property detection method. The method comprises the following steps: sampling three times, and during sampling each time, selecting at least four weft direction testing pieces and at least four warp direction testing pieces on the same to-be-sampled textile; taking apart the outer edge raw yarn of the length side of each testing piece uniformly, and adjusting the widths of the testing pieces to be 40-60 mm; testing one by one by adopting a tensile measuring machine, wherein in the testing environment, the humidity is 57% RH, the temperature is 25 DEGC, the cloth pulling speed is 100-150 mm / min, the maximum force value is 500 N, the maximum elongation value is 40-50%, and the measurement length of each testing piece is 200-300 mm per segment; removing the abnormal value, and retaining the test results of three weft direction testing pieces and three warp direction testing pieces. A reasonable and effective detection method is formed in the invention, various tensile testing numerical values of the textile can be objectively detected, so that the physical condition thereof is determined, the rupture capacity and tearing capacity of the textile are objectively responded, and the product quality of a manufactured textile is conducive to be improved.

Description

technical field [0001] The invention relates to the performance testing technology of textiles, in particular to a method for detecting physical properties of high-density textiles. Background technique [0002] In the production process of products in different fields, how to improve product quality and further reduce the defective rate has always been the goal pursued by every enterprise. High-quality products are also an important manifestation of enterprise competitiveness. Therefore, in the field of textile technology, R&D personnel are also constantly working on the quality of their own textiles, and have produced testing items for textiles. There are many items that must be checked for physical property testing of different textiles. Through the testing of these items, it can be directly judged The quality of textiles is good or bad. [0003] The quality is directly related to whether it can meet the needs of various users. If the performance of the applied textile i...

Problems solved by technology

In addition, the factors that affect the performance of textiles also include the color difference index of the fabric. Different batches of dyed fabrics of the same type will have batch differences. For the quality of fabric products, the color difference between the left and right of the fabric is also not allowed in terms of quality requirements

[0005] Those skilled in the art have analyzed the deficiencies of the existing known technologies. In the past, when the physical properties of textile products were tested, it was not enough to characterize the physical properties of the textile itself, especially when reflecting the fabric breaking ability and tearing ability of the textile. It seems that it is not objective enough. After the testing process is carried out, in fact, many invalid test results are produced. Even if it is completely replaced by automatic equipment, due to the inappropriate sampling method, it still cannot reflect the physical properties of the fabric, which will improve the quality of the product and the quality of the product. Productivity gains, etc., are not beneficial
