polypropylene staple fiber is a thermoplastic body, and it has no body odor (non-toxic, odorless, tasteless). It is hard to touch and is thinner (the density is only 0. 90--"0. 91g/cm3, which is a particularly light chemical fiber. One). In addition, the personality is relatively stubborn, how to fight, how to fall, do not jump, the eyes are not sloppy, the meat does not hurt, pat the dust, is a hero. (100% plastic, good recovery performance after deformation).

polypropylene staple fiber is a very smart young man, it is a little glass heart (large brittleness, especially low temperature brittleness), sometimes it is relatively cold (higher crystallinity), can not withstand too much grievance (molecular polarity), and Others are not very gregarious (mixed with other polymers (such as plastics, rubber) and inorganic fillers and poor adhesion), so the life circle is relatively small. However, after eating spinach (modification), it is just like changing a person. It can be used with a variety of people to make a mountain (compatibility enhancement), and it can also be transformed like Altman, playing monsters (strengthening) Fire extinguishing (flame retardant modification), stealing other people's skills (graft modification). In short, the spinach belly, the gods can not stop.

Physical modification of polypropylene staple fiber

1) Filling modification: adding a certain amount of inorganic filler and organic filler to the polypropylene short fiber to improve certain properties of the product and reduce the cost of the material.

2) Reinforcement modification: The addition of the fibrous material to the polypropylene staple fiber can significantly increase the strength of the polypropylene staple fiber material.

3) Blending modification: blending other plastics, rubber or thermoplastic elastomers with polypropylene short fibers to produce a polymer alloy having these polymer properties.

Chemical modification of polypropylene staple fiber

1) Graft modification: : Grafting modification of polypropylene staple fiber is to introduce other groups in pp molecule, which can not only give certain special functions of polypropylene staple fiber, but also maintain the excellent properties of polypropylene staple fiber. ;

2) Copolymerization modification: refers to the modification of the propylene monomer mainly in the polymerization stage by using a catalyst;

3) Crosslinking modification: In order to improve the morphological stability, creep resistance, increase strength and heat resistance, and melt strength, the molding cycle is shortened.

After decades of development. polypropylene staple fiber has a certain understanding of its own ability. Therefore, in daily life, he slowly changes his own by changing his own ability. Today, like air (film, plastic bags, cups, chairs, auto parts, electronic appliances and other plastic products), he is infiltrated into people's lives, and people can't live without him. Everything you see in life has him, the place you can't see (plastic pipes), and he still has him.
