Polypropylene fiber is synthesized from propylene polymerization and is made into synthetic fiber, which is called polypropylene in our country. Polypropylene, which began industrializing in 1957, is the cheapest synthetic fiber in the world because it is only made from propylene, which is extremely rich, cheap and easy to produce. With good performance and fast development, polypropylene is the fourth largest producer in the world after polyester, nylon and acrylic. Polypropylene has the characteristics of small density, low melting point, high strength and acid base, etc., so it is mainly used in industries, interior decoration, clothing, non-woven fabric, etc.

The main products of polypropylene include staple fiber, filament, nonwoven fabric, tobacco and bulk continuous filament (BCF), which are used for packaging, cigarette filter, carpet, non-woven fabric, clothing and other products. In addition to taking, industrial use of polypropylene is the most active market, and consumption growth in medical and health materials is also fast.

Polypropylene fabrics have the advantages of high strength, small density and good corrosion resistance. Polypropylene fabric defect is: owing to the polypropylene is the height of the neat rows of crystals, polar groups, from the point of view of its structure and no has the ability to respond to the group, plus the moisture absorption rate is very small, so the difficulty of dyeing. It can solve the problem of dyeing hard by using raw liquid colouring spinning. In addition, the light resistance of polypropylene is poor. Polypropylene is in high temperature season, after the long exposure of sunlight, easy to age, and the strength is reduced. Especially when it's wet, it's more serious. Therefore, the polypropylene fabrics and blended fabrics should not dry in the sun after washing, to dry in a cool and ventilated place. Polypropylene is easy to age at high temperature, so the thermal stability of fiber is not good enough.

Polypropylene fabrics

The polypropylene fabric has pure spinning, blending and interweaving, among which, blends and interwoven fabrics are more closely matched with cotton fiber, such as c/cotton muslin, propylene/cotton colored yarn, etc. A pure polypropylene fabric is represented by a parka.

(1) polypropylene fiber fabric

1. Pat pat topcoat topcoat?? Is a dope shading polypropylene looped yarn weaving wool-like fiber fabric, has a unique face loop style, colour and lustre is bright beautiful, its light and warmth, MAO sense is strong, its biggest advantage is washable quick-drying. Suitable for youth clothing and children's coats.

2. The superfine fiber fabrics with superfine polypropylene and polyester FDY such draw textured yarn (DTY) as raw material, made of knitted or woven fabrics, applicable to the production of high-grade clothes, T-shirt, underwear, pajamas, wearing all kinds of fashion and socks, etc. It can also be used in bedding, decorative materials (curtains, table cloth), towels, hats and medical supplies.

(2) polypropylene blended fabric

Polypropylene fiber is suitable to be blended with cotton or viscose fiber into various fabrics. At present, the polypropylene fabric produced in our country has 35% cotton, 65% propylene/cotton colored linen yarn. Polypropylene and cotton each account for 50% cotton/propylene cloth or white cloth.

1. Propylene/cotton colored yarn is made of propylene/cotton (65/35) yarns. It has strong wear resistance, strong appearance and good dimensional stability. Use as a military raincoat, mosquito net, etc.

2. The appearance of c/c/cotton fine cloth/cotton fine cloth, with small shrinkage, strong and durable, has the advantages of easy to wash and quick drying, and has the style of polyester/cotton fabrics. The price is much cheaper than the polyester/cotton fabric.

Polypropylene is limited to some extent, in terms of taking the polypropylene is mainly used for carpets, including carpet backing and suede), decorative cloth, geotextile, non-woven cloth, rope, belt, fishing nets, construction materials, packaging materials, etc. The polypropylene nonwoven fabric is notable for the large number of applications of baby diapers and women's sanitary pads. Made from the hollow fiber of polypropylene fiber, it is light, warm and elastic.
