( Spun-bonded non-woven what are the physical properties, you know? ]

Spun-bonded non-woven fabric is a new type of environmentally friendly materials, people can according to its characteristics, used in different occasions. Spun-bonded non-woven production generally can be divided into four steps: spinning, drawing and into the net, heat-sealing, winding cutting. Add polymer slice, masterbatch, or other material after joining hopper, respectively, after mixing hopper full uniform mixing, feeding screw heat melt extrusion, thus make spun-bonded non-woven fabrics. Spun-bonded non-woven fabric for the ivory high crystalline polymer, non-toxic, tasteless very stable, water in the water the bibulous rate of 14 h is only 0. 01%. 8 ~ 150000 molecular weight, good formability. But due to the shrinkage rate, the original wall products easy sag, product surface gloss, easy coloring. High crystallinity and materials, neat structure, and thus has excellent mechanical properties, the strength and hardness, elasticity, are better than high density PE ( HDPE) High. Spun-bonded non-woven fabric can be bending fatigue resistance ( 7×10^7） Time opening and closing of folding bending without damage, dry friction coefficient and nylon are similar, but not as good as nylon under oil lubrication. Spun-bonded non-woven products, moreover, excellent mechanical properties, its tensile strength, elongation at break, tear strength and other pointer is superior to dry, wet, melt-blown non-woven fabric, especially in recent years, spun-bonded method in production scale, technology and equipment, and the rapid development of the product market development, greatly expands the application fields of spun-bonded non-woven fabrics. Dongyang lai chi environmental protection technology co. , LTD. Has always been committed to medical non-woven fabric, spun-bonded non-woven fabric, elastic non-woven, non-woven products research, development and production. The production of non-woven products can be in the source, recycle and reuse, can no longer worried about health problems. Lai chi can provide customized for clients of various non-woven products needed - Medical non-woven fabric, elastic nonwovens, spun-bonded non-woven fabrics.
