Textile fabric testing is also called textile testing, which refers to the qualitative or quantitative testing of the quality and performance of textile fabrics according to relevant standards through physical and chemical methods and the test report made. Therefore, whether a textile fabric is qualified or not depends on the textile fabric standard. What are the testing standards for textile fabrics?
1. Textile fabrics Physical inspection: It mainly uses various instruments, meters, equipment and measuring tools to detect the physical properties or physical quantity data existing in the textile fabrics, and then carries out systematic sorting and analysis to determine whether the physical properties of the textile fabrics are stable and whether the fabric quality is good or bad.
2. Chemical inspection of textile fabrics: It is similar to physical inspection. Then various chemical technologies and instruments and equipment are used to take samples of textile fabrics for testing and analysis to analyze the chemical properties, chemical composition and content of the fabrics. This is also a way to judge how many chemicals are present in the fabrics and determine whether the fabrics are safe and healthy. It is a very important reference standard to judge the quality of fabrics.
3. Combustion identification
The quality of textile fabrics is actually very easy to distinguish, but we have forgotten that the simplest method is the best. So how on earth should we distinguish the quality of textile fabrics? The answer is combustion. This method is often used to judge the quality of fabrics. Textile fabrics are also a kind of fabrics and can be used naturally. It is understood that the reaction of textile fabrics with different components after combustion is different, so the quality of textile fabrics can be judged according to these different reactions.
4. Good and bad judgment
For example, the textile fabric of cotton fiber will spread immediately once it is burned, and the burning speed of the fabric is very fast, and the flame of the fabric is yellow, emitting blue smoke. At the same time, the cotton fiber will emit bursts of paper smell when it is burned, and after burning, only a little gray or black ash will be left. If this reaction, the textile fabric of cotton fiber is very good, On the contrary, the fabric quality is not pure, and other ingredients are added inside. The quality of other textile fabrics can also be judged in this way.
Formal textiles must undergo systematic textile testing before leaving the factory. Textile testing includes component testing, color fastness testing, dimensional stability testing, etc. Therefore, when selecting textiles, such as fabric curtains and curtain products combed by shrinkproof, anti-aging, soft, flat, etc., you should pay attention to whether the fabric is marked with formaldehyde concentration. You can also smell whether the textile has a bad smell. If the product releases a pungent smell, it is likely to have residual formaldehyde in the room. It is best not to buy it.
Generally speaking, the product logo of Reliable Company is relatively complete, and the detailed address and telephone number are clearly marked; Some enterprises will also carry out product quality certification and other certification (enterprises can come to me if they have this demand), and this kind of product is more secure and safer. If the product logo is incomplete, non-standard, inaccurate, or the product packaging is not smooth, or the packaging printing is blurred, it should be carefully selected.
