Advantages And Characteristics Of Polypropylene Non Woven Fabric
- Jun 23, 2017 -

Polypropylene Non Woven Fabric to grow the important news is that it is synthetic polymer as raw material, the law to dominate the chemical fiber spinning business, in the polymer spinning process continues filament, after spinning into the network after the direct bonding system Into a non-woven fabric, the production is very simple and fast, and dry non-woven processing technology control, eliminating the fiber crimping, cutting, packaging, transportation, assimilation, combing and a series of cumbersome core process, such continuation, Multi-volume production of the most obvious end is to spunbond products cost of land, the same character, market competitiveness, in the use of disposable and enduring all kinds of use can enter the textile, paper and film market size in. Second, due to the large number of spunbond Non Woven Fabric operating polypropylene as an important raw material, its price, processing, production costs and other aspects of the possession of a lot of advantages, but also greatly enhanced the spunbond Non Woven Fabric continued the growth of property. In addition, the spunbond Non Woven Fabric product mechanical properties, its tensile strength, elongation at break, tear strength and other indicators are better than dry, wet, melt blown non-woven, especially over the past few years Sticky in the production line size, technology and equipment and product market excuse the active growth, greatly expanding the spunbond non-woven operation scale.

Spunbond production process and chemical fiber spinning the biggest difference is the use of air drawing and direct into the network, is the spinning method of the draft into the focus of the problem, the previous draft is the use of mechanical draft preparation, fiber Monofilament thick, uneven shop. At present, the world's countries spunbond production equipment have been used to draft technology, due to air flow drafting differences, the composition of spunbond production line has three different situations, both tube draft, wide slit draft, narrow seam Extension and so on.

Spunbond Non Woven Fabric technology has always been to mention the ability to cross the production line and to solve the uniformity of Non Woven Fabric, decorative algae ornaments, feel rough and other issues to improve the spunbond Non Woven Fabric strong, excellent flexibility , Uniformity and comfort, hygroscopicity and other properties.

Fine dyed spunbond Non Woven Fabric can directly improve the spunbond Non Woven Fabric excellent flexibility and comfort and other issues. However, there are technical bottlenecks in the spunbond method, such as fine Dan can increase the number of fibers in the area of spunbond Non Woven Fabric, and the "connection point" between fiber and fiber grows , The product will become even more uniform, the coverage rate also forward.
