spunbond non-woven fabric is a type of non-woven fabric that uses polypropylene as its raw material. It is produced by drawing the polymer into a network at high temperature and then bonding it with heat. It is widely used in various fields because of its simple process, large production capacity, and non-toxicity to the human body. What are the characteristics and advantages of spunbond non-woven fabric?
The rapid development of spunbond non-woven fabric is mainly due to the use of synthetic polymers as raw materials. The spun network is directly bonded into non-woven fabric. The manufacturing method is very simple and fast. This method uses the principle of chemical fiber spinning to prepare continuous filaments during the polymer spinning process. The obvious effect of this continuous and batch production is the reduction of the cost of spunbond products, stable quality, strong market competitiveness, and can be used for various disposable and durable purposes, entering the market domain of textiles, paper, and film. Compared with the dry non-woven fabric processing technology, it can save a series of tedious intermediate processes such as fiber winding, cutting, packaging, transportation, mixing, and combing. Secondly, it has greatly promoted the continuous development of spunbond non-woven fabric industry. In addition, the mechanical properties of spunbond non-woven fabric produced by the spunbond process are excellent, and the indicators such as tensile strength, fracture elongation, and tear strength are better than those of dry, wet, and melt-blown non-woven fabrics. Especially in recent years, due to the fact that spunbond non-woven fabrics are mainly made of polypropylene, they have many advantages in terms of price, processing process, and production cost. Due to the rapid development of spunbond technology, equipment, and product market expansion.
The biggest difference between the production process of spunbond non-woven fabric and chemical fiber spinning is the use of air flow drawing and direct networking. Therefore, the spunbond process has become a mid-range problem in technology. Traditional drawing uses mechanical drawing, the fiber monofilament is thick, and the network tension is uneven. At present, there are three different forms of production lines for spunbond fabrics in the world. Spunbond production equipment in various countries around the world has adopted pneumatic drawing technology. Due to different pneumatic drawing methods, such as tubular drawing, wide and narrow slot drawing, narrow slot drawing, etc.
The aim of the technology of spunbond non-woven fabric is to improve the production capacity of the production line, thereby improving the strength, softness, uniformity, comfort, and moisture absorption performance of the spunbond non-woven fabric and solving the problems of uniformity, concealment, and roughness of the non-woven fabric. Spunbond non-woven fabric can directly improve the softness and comfort of spunbond non-woven fabrics and other issues.
