Non-woven fabric is a kind of nonwoven fabric in accordance with the production technology of spun-bonded, water, heat sealing, acupuncture, melt-blown, water and other practices, each production process of fabric also have very big difference in the characteristics, spun-bonded non-woven fabrics on the market more commonly used in the production of non-woven bag. We usually know some properties of non-woven fabric moisture, lightweight, easy to decompose, non-toxic non-irritating taste, color rich, the price is low. With environmental protection bags of promoting the application of nonwovens in recent years rapid development, in the clothing, household decoration, industry, agriculture, medicine has a wide range of applications.
The quality of non-woven fabric mainly influenced by particles of raw materials, production of non-woven fabrics on the market have a difference to materials and new materials, new materials compared to expected more than thousands of tons of price, so a non-woven bag will differ is more, the prices on the us by checking the appropriate parameter to measure the quality of non-woven fabrics.
At present, we mainly through the following several aspects to test:
1, the stretchability of cloth, wear-resisting performance.
2, fabric after friction fastness, color fastness after washing.
3, antistatic and the combustion performance of cloth.
4, moisture regain, breathable, moisture permeability oil rate and the purity of cloth.
