Product features and applications of polypropylene non-woven fabrics

Compared with other types of non-woven products, polypropylene non-woven fabrics have unparalleled product advantages and have been widely used in agriculture, medical and health, clothing and construction industries. In the face of the current highly competitive non-woven market, If a non-woven fabric processing enterprise wants to stand firm, it must adopt advanced processing technology. While maintaining its own advantages, it can quickly transform the existing technical advantages into product characteristics advantages, and continuously expand the application of polypropylene non-woven fabrics. 

Product features and applications of polypropylene non-woven fabrics:

Raw material: polypropylene (PP)

Polypropylene is a kind of polymer commonly used in the spinning process. The main performance parameters are isotacticity, melt index (MFI) and ash content.

The spinning process requires that the isotacticity of polypropylene is above 95%, and if it is less than 90%, spinning is difficult.

During the polymerization process, three configurations of polymers can be produced due to the different positions of the methyl groups in the steric space.

Features: high strength, good high temperature resistance, aging resistance, UV resistance, high elongation, good stability and air permeability, corrosion resistance, sound insulation, moth-proof, non-toxic.

Process flow: polymer (polypropylene + return material) – large screw high temperature melt extrusion – filter – metering pump (quantitative conveying) – spinning (up and down suction at the entrance of the wanton) – cooling – Air Traction – Net curtain forming – Upper and lower pressing rollers (pre-reinforcement) – Mill hot rolling (reinforcement) – Winding – Reverse distribution and slitting – Weighing and packaging – Finished product storage


Generally, the two-way fastness is good, the rolling point of the general spunbond non-woven fabric is diamond-shaped, the characteristics of wear resistance, firm hand feeling, etc. make it the best choice for making such products.

Application field:

Clothing: clothing lining, winter thermal insulation materials (ski shirts, quilts, the inner core of sleeping bags), work clothes, surgical gowns, protective clothing, suede materials, clothing accessories

Daily necessities: non-woven bags, flower packaging cloth, luggage cloth, home decoration (curtains, furniture covers, tablecloths, sofa beds, window covers, wall coverings), needle-punched chemical fiber carpets, coating materials (artificial leather)

Industry: filter materials (chemical raw materials, food raw materials, air, machine tools, hydraulic systems), insulating materials (electrical insulation, thermal insulation, acoustic insulation), paper blankets, car shells, carpets, car seats, car door inner layers

Agriculture: roof material for greenhouse (agricultural hotbed)

Medical and health: non-wrap medical, wrapping medical, other sanitary civil engineering: geotextile

Construction: Rainproof materials for roof sheds Military: breathable anti-virus suits, anti-nuclear radiation suits, space suit inner layer cloth, military tents, war emergency room supplies.

At present, the use of various polypropylene non-woven products in all walks of life is also increasing. Due to its wide application in clothing and medical and health fields, polypropylene non-woven fabrics have become indispensable for the processing of clothing and medical and health materials. Less raw materials, with the continuous innovation of various non-woven products, non-woven products of various types and product characteristics will have more extensive applications in the future!
