Detailed description
The important reason for the rapid development of the spunbond method is that it uses synthetic polymers as raw materials. This method uses the principle of chemical fiber spinning to make non-woven fabrics by direct bonding of continuous filaments in the polymer spinning process after spinning into a web. The manufacturing method is very simple and fast. Compared with the dry non-woven processing technology, it saves a series of tedious intermediate processes such as fiber crimping, cutting, packaging, transporting, mixing and carding, the most significant effect of this continuous, high-volume production is to reduce the cost of spunbonded products, stable quality, strong market competitiveness, and can enter the market of textiles, paper and films in various uses of disposable and durability. Secondly, because the spunbonded non-woven fabric uses a large number of polypropylene as the main raw material, it has many advantages in terms of price, processing, and production costs, which greatly promotes the sustainable development of the spunbonded non-woven fabric industry. In addition, spunbonded non-woven products have excellent mechanical properties, and their tensile strength, elongation at break, tear strength and other indicators are better than dry, wet and meltblown non-woven fabrics. Especially in recent years, the spunbonded method has developed rapidly in the production line scale, technology and equipment and product market development, greatly expanding the application field of spunbonded non-woven fabrics.
The biggest difference between spunbond production process and chemical fiber spinning is the use of airflow drafting and direct mesh formation, so the drafting of spunbond method becomes the core problem of technology. In the past, mechanical drafting was used, and the fiber monofilament was thicker and the mesh was uneven. At present, the world's spunbond production equipment has been using airflow drafting technology, due to the different ways of airflow drafting, the formation of spunbond production line has three different forms, both tube drafting, wide slit drafting, narrow slit drafting and so on.
Spunbond non-woven technology has been to improve the capacity of the production line and solve the uniformity of non-woven fabrics, covering, feel rough and other issues, in order to improve the spunbond non-woven fabric strength, softness, uniformity and comfort, moisture absorption and other properties.
