The advantages and characteristics of polypropylene non-woven fabric

Important sign of the growth of the polypropylene non-woven fabric to loose is it using synthetic polymer as raw materials, the dominating chemical fiber spinning things, continue in the process of polymer spinning yarn, the spinning web forming after direct bonding, made of non-woven fabrics, production preparation is very simple and quick, and dry non-woven processing craft control, eliminating the fiber crimp, cutting, packaging, transport, the core of assimilation, comb and a series of complicated process, this kind of continuation and measure of production to the most is the end product is to make the method of spun-bonded capital land, moral character is constant and strong market competitiveness, in the abandoned and durability, each kind of useless can enter into the market size of textile, paper and film. Second, due to the quantities of operating method of spun-bonded non-woven polypropylene as raw material, its price, processing, production capital takes up a lot of aspects such as the upper hand, also greatly improve the spun-bonded non-woven property continues to grow. In addition, the method of spun-bonded non-woven products of excellent mechanical properties, its tensile strength, elongation at break, tear strength and other pointer is superior to dry, wet, melt-blown non-woven, out of line is coming years spun-bonded method in production scale, craft, equipment and product market investing place the adjustable growth, greatly expanded the operation of the spun-bonded non-woven. Spun-bonded method production process and chemical fiber spinning drafting of most is in the air and directly into the net, is a draft of the spun-bonded method caused craft focal point question, drafting is to use mechanical drawing of the past, fiber monofilament coarser, web is not uniform. Today, the world's nations spun-bonded production equipment have been adopting airflow drafting skills, because the air drafting divisions, there are three kinds of production of spun-bonded method divided situation, both tube drawing, the width of slit type draft, narrow slot and drafting, etc. Method of spun-bonded non-woven craft consistent across the line of ability and solve the uniformity of non-woven, polishing and embellishments in writing, feel is rough and other issues, by the method of improved spun-bonded non-woven powerful, flexible, uniformity, and comfortable, moisture absorption performance. Fine Dan the spun-bonded non-woven fabrics can be directly modified method of spun-bonded non-woven optimal problem such as flexible and comfortable. However, fine Dan spun-bonded law of has the bottleneck of craft, such as fine Dan, can make the spun-bonded non-woven fiber number of unit area growth, 'connecting point' between the fiber and fiber will increase, uniform product would be double, cover rate also.
