Silk products use high-strength polypropylene
In recent years, with advances in modern technology and industry continue to expand the field of textiles, high-strength polypropylene filament because of its unique economic factors and performance factors to be widely used in the following industries:

 
(A) line class
Made of high strength polypropylene filament polypropylene line, because of its low price, high strength, anti-aging, wear, resistance to seawater corrosion, flexibility and good features, mainly used in sewing bags, soccer, volleyball, baseball, yo-yo wire, cable wire, with wire nets, shoes, feed line, luggage line, kite line, twisted edge, waste sideline, FIBC dedicated line, sewing thread, tied note lines, curtain wire, building wire, construction wire , ribbon wire, toys, wire, umbrella wire line, optical cable around the bar line, fishing net cord and other industries.

 
(B) rope class
Made of high strength polypropylene filament ropes and construction, transportation, agriculture, fishing, sports net, its tensile strength, wear resistance, corrosion resistance, light weight safety.

 
(C) with class
The use of high-strength polypropylene filament of high strength, lightweight, and high tensile strength, can be made for higher safety factor of the flexible container bags, seat belts, high-pressure fire hose and agricultural water use with other products.

 
(D) cloth
With high-strength woven geotextile polypropylene filament, for highways, railways, airports, dikes, canals, reservoirs, harbors and bridges projects, with no direct air links, build cofferdam, dam drainage and playing speed, high efficiency, investment, and good quality, especially in the case of large load bearing, woven geotextile is more than the number of unique non-woven geotextile. Its acid and alkali, corrosion resistance, high strength, non-absorbent, light weight, good stability, good peel the filter material, etc., can be made of high-strength polypropylene filter cloth, mainly used in metallurgy, mineral processing, chemical industry, light industry, food, environmental protection and other industries.

 
(E) Polypropylene staple fiber
Polypropylene round, trefoil, triangular short fibers, are widely used in cement concrete, paper, sanitary materials.
 
High-strength polypropylene Silk - Performance
Our company developed high-strength polypropylene filament, because of its high strength (strength greater than 8g / d), anti-aging, acid, light weight, wear-resistant, low thermal conductivity, resistance to seawater corrosion, does not absorb moisture, etc., are widely used on the safety belt, flexible container bags, geotextiles, industrial filter cloth, ropes, cables, high-pressure fire hose, conveyor belt, industrial sewing thread, fiber concrete cracking, Peng canvas and other fields, is an alternative polyester, nylon, Polyethylene, nylon fiber material of the new ideal.
