Nowadays, as people pay more attention to environmental protection, new environmentally friendly materials have attracted more and more attention, and non-woven fabrics are one of them.
This material is a fabric that does not require spinning and weaving. It just arranges short textile fibers or filaments in a directional or random manner to form a fiber mesh structure, and then uses mechanical or thermal bonding to Or reinforced by chemical methods.
The exact name of non-woven fabrics should be non-woven fabrics, or non-woven fabrics.
Because it is a fabric that does not require spinning or weaving. It just orients or randomly arranges short textile fibers or filaments to form a fiber mesh structure, and then uses mechanical, thermal bonding or chemical methods to reinforce it. become.
There are many types of non-woven fabrics, and pp spunbond non-woven fabric is one of them.
?PP spunbond non-woven fabric is a non-toxic, odorless and tasteless milky white highly crystalline polymer with a density of only 0.90–“0.91g/cm3. It is one of the lightest varieties of all plastics at present.

It is particularly stable in water, with a water absorption rate of only 0.01% and a molecular weight of about 80,000 to 150,000.
The formability is good, but due to the large shrinkage rate (1%~2.5%), thick-walled products are easy to dent, and it is difficult to meet the requirements for some parts with high dimensional accuracy. The surface of the product is glossy.
We sell pp spunbond non-woven fabrics and undertake various filter material coating processing services. Our company will perform coating processing according to the coating substrate provided by the customer or the coating substrate specified by the customer.
The key to its technology is the optimized combination of speed ratio, pressure ratio, operating temperature and other parameters. Our company can realize online control of air permeability, thickness and void ratio according to the ratio and pore-forming medium to meet the different needs of users.
