What are the main aspects of non-woven testing

Non-woven fabric is a kind of non-woven fabric. According to the production process, there are spunbonded, spunlaced, heat-sealed, needle punched, melt blown, hydrophilic, etc. The characteristics of the fabric of each production process will also be very different. Spinning on the market Adhesive non-woven fabrics are generally used in the production of non-woven bags. Some of the characteristics of non-woven fabrics that we usually know are moisture-proof, light texture, easy to decompose, non-toxic and non-irritating, rich in color, and low price. With the vigorous promotion of environmental protection bags, the application of non-woven fabrics has developed rapidly in recent years, and has been widely used in clothing, home decoration, industry, agriculture, and medicine. The quality of non-woven fabrics is mainly affected by the raw material particles. The non-woven fabrics produced on the market have the difference between recycled materials and new materials. The price of new materials per ton is thousands of times higher than that of recycled materials. Therefore, a non-woven fabric The price on the cloth bag will vary a lot, and we measure the quality of the non-woven fabric by checking the corresponding parameters. At present, we mainly use the following aspects to test: 1. The stretchability and wear resistance of the fabric. 2. The color fastness of the cloth after rubbing and the color fastness after washing. 3. Antistatic and burning performance of cloth. 4. Moisture regain, air permeability, moisture permeability, oil content and fabric purity.
