The specific embodiment
By the composite material for cars manufacture method of a kind of high-content regenerated fiber of the present invention, take following steps:
The first step: polypropylene fibre, terylene, regenerated fiber are mixed by weight percentage, and the usage ratio of polypropylene fibre, terylene, regenerated fiber is by weight percentage: polypropylene fibre 58%～70%, terylene 2%～0%, regenerated fiber 40%～30%.Wherein regenerated fiber is based on cotton fiber, and the polypropylene fibre specification is 10dtex * 65mm; The terylene specification is 3dtex * 65mm.
The raw material of composite material for cars of the present invention specifically is made up of polypropylene fibre, terylene and regenerated fiber.Wherein regenerated fiber is meant the waste material of clothing factory's leftover pieces, automotive upholstery factory leftover pieces or textile mills, obtained staple fibre after shredding, and its main component is terylene and cotton, wherein terylene content can be 10%～65%.
Second step: above-mentioned three kinds of fibers are mixed through 3～5 shreddings, mix.The purpose that shredding mixes is to make fiber more fluffy, mixes, thereby makes the technology of back operation (combing) be easy to carry out, and finally makes in the finished product various Fiber Distribution even.
The 3rd step: with the fiber process combing that mixes, the fiber web that comb is good is compound, through 3～5 pinprick reinforcements.Combing and acupuncture also help next step hot-roll forming except further mixing.The main effect of combing is to allow fiber arrange in order.
The 4th step: make polypropylene fibre fusion in the Nomex by hot rolling, thereby form a kind of complex, make coiled material, be cut into the automobile felt then by the regenerated fiber Reinforced Polypropylene.
Polypropylene fibre in the composite material for cars of the present invention is a kind of low-melting fiber, just can fusion when being heated to 170 ℃～180 ℃, in this composite as fertile material, just as the cement in the armored concrete; And cotton fiber (the main body composition in the regenerated fiber) is as reinforcing agent, and it acts on as reinforcing bar; Terylene can also make processes more easy in the carding process of producing except that as the reinforcing agent, and the various Fiber Distribution that make it final products automobile felt are more even.
Selection and ratio for raw material in the manufacture method of the present invention seem very important, because regenerated fiber content is many, felt is yielding, are difficult for processing; Polypropylene fibre content is many, felt meeting hardening, and sticking to mould, but after adding a certain amount of terylene, product is the demoulding easily just.
