Mechanical properties of pp non-woven fabric
PP non-woven fabric technology has always been to improve the capacity of the production line and solve the problemsof non-woven fabric such as uniformity, covering, rough handle, etc, to improve the strength, softness, uniformity,comfort, moisture absorption and other properties of spunbonded non-woven fabric. Next, Chengxin non-woven fabricsmall knitting explains how the mechanical properties of PP non-woven fabric products are.
The important reason for the rapid development of spunbonded method is that it uses synthetic polymers as rawmaterials. This method uses the chemical fiber spinning principle to make continuous filaments in the polymer spinningprocess, which are directly bonded to form PP non-woven fabric after spinning, and the manufacturing method is verysimple and fast. Compared with the dry non-woven fabric processing technology, it saves a series of tediousntermediate processes such as fiber crimping, cutting, packaging, transportation, mixing, carding, etc The mostsignificant effect of mass production is to reduce the cost of spunbonded products, stabilize their quality, andstrengthen their market competitiveness. They can enter the market field of textiles, paper and film in a variety of usessuch as disposable and durable.
Because PP non-woven fabric uses a large number of polypropylene as the main raw material, it has many advantages inprice, processing process, production cost, etc, which also greatly promotes the sustainable development of PP non-woven fabric industry.
Dp non-woven fabric has exce ent mechanica properties, and its tensile strencth, elongation at break, tear strength anoother indicators are better than those of dry, wet and melt blown non-woven fabrics. Especially in recent years, the rapiddevelopment of spunbond in production ine scale, technology, equipment and product market development has greatexpanded the application field of Pp non-woven fabrics.
The biggest difference between the production process of spunbonded method and chemical fiber spinning is that airdraft and direct netting are adopted, so the drafting of spunbonded method has become the core technical problem. Inthe past, mechanical drafting was adopted, and the fiber monofilament is relatively thick and the netting is uneven. Airflow drafting technology has been adopted in the spunbonded production equipment all over the world. Due todifferent air flow drafting methods, there are three different forms of spunbonded production lines, namely pipe typedrafting, wide narrow slot drafting, narrow slot drafting, etc.
