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 imported PP polypropylene filament non-woven fabrics are one of them.
Imported PP polypropylene filament 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 currently.
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.
Imported PP polypropylene filament non-woven fabric has good heat resistance, with a melting point of 164~170℃, and the products can be sterilized at temperatures above 100℃.
It will not deform at 150℃ without being affected by external force.
The embrittlement temperature is -35°C. Embrittlement will occur below -35°C, and the heat resistance is not as good as PE.
