[Do you know the physical properties of spunbond nonwovens?]
Release date:[2019/12/5] Is reading[917]次

spunbond non-woven fabric is a new type of environmentally friendly material. People can use it in different occasions according to its characteristics. The production of spunbond non-woven fabrics can generally be divided into four steps: spinning, drafting, web forming, heat sealing, and winding slitting.


After adding polymer chips, masterbatches or other added materials to the hopper, they are fully stirred and mixed evenly through the mixing hopper, fed into the screw, heated and extruded, so as to make a spunbond non-woven fabrics.


spunbond non-woven fabric is a non-toxic, odorless, milky white highly crystalline polymer, which is particularly stable to water, and the water absorption rate in water for only 14 hours is only 0.01%. The molecular weight is about 8 ~ 150,000, and the moldability is good. However, due to the large shrinkage rate, the original wall product is easy to sag, the surface of the product is good, and it is easy to be colored. In addition, the material has high crystallinity and a regular structure, so it has excellent mechanical properties. Its strength, hardness, and elasticity are higher than high-density PE (HDPE).


The outstanding feature of spunbond non-woven fabric is its bending fatigue resistance (7 × 10 ^ 7). It can be bent without opening and closing without damage. The coefficient of dry friction is similar to nylon, but it is not as good as nylon under oil lubrication.


In addition, spunbond non-woven  products have excellent mechanical properties, and their tensile strength, elongation at break, and tear strength are better than those of dry, wet, and meltblown nonwovens, especially in recent years. The rapid development of production line scale, technology and equipment and product market development has greatly expanded the application fields of spunbond non-woven .


Dongyang Laichi Environmental Protection Technology Co., Ltd. has always been committed to the research, development and production of medical non-woven fabricsspunbond non-woven fabricselastic non-woven fabrics and non-woven fabrics. The non-woven products produced can be exchanged, recycled, and reused, and can no longer be a concern for health problems.


Lai Chi can provide customers with a variety of non-woven products - medical non-woven fabrics, elastic non-woven fabrics, and spunbond non-woven fabrics.


Laichi offers more than just high quality spunbond non-woven fabrics!
