The exact name of imported PP polypropylene filament non-woven fabric should be “non-woven fabric”, or “non-woven fabric”.
, because it is a fabric that does not require spinning or weaving.
It just orientates or randomly arranges textile short fibers or filaments to form a fiber mesh structure, and then uses mechanical, thermal bonding or chemical methods to reinforce it.
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, and the surface gloss of the product is good.
In 2015, polypropylene spunbond and melt-woven fabric manufacturers in the nonwovens industry took full advantage of the market value of this technology and gained momentum.
For example, Scalter, an Argentinian nonwoven company, announced the acquisition of a polypropylene spunbond production line with an annual output of 8,000 tons of nonwovens from a Chinese company.
It is reported that the production line includes two spunbond production lines, two chemical bonding lines, a thermal bonding line, a printing press and a knitting machine. It is installed in the Buenos Aires factory to improve Improve Scalter’s existing operational efficiency.
