Abstract
The invention discloses a process for manufacturing a non-woven fabric by waste PET (polyethylene terephthalate). The process includes the steps: crushing and drying recycled PET films; stirring the crushed PET films, adding ethylene-octanoic acid copolymer and stirring the films and the copolymer into mixed materials; throwing the mixed materials into a double-screw extruder and extruding and plasticizing the mixed materials into particles; throwing the plasticized into a spinning manifold; hot-rolling the spun materials in a netting manner. By the aid of high strength and fine rigidity of the waste PET, the durable non-woven fabric is manufactured, PET waste materials can be conveniently and effectively disposed, and production cost is saved while environmental pollution is reduced.
Description
Technical field
The present invention relates to the nonwoven fabric manufacturing technique, relate in particular to the technique that a kind of PET of utilization reclaimed materials is made nonwoven fabric.
Background technology
The PET film has intensity height, good rigidly, transparent, glossiness high; Odorless, tasteless, colourless, nontoxic, outstanding obdurability; Its TENSILE STRENGTH is PC film, nylon membrane 3 times, and impact strength is 3-5 times of PP film, and fabulous ABRASION RESISTANCE, folding resistance, pinhole resistance and tear resistance etc. are arranged; Heat-shrinkable is minimum; Have good antistatic behaviour, easily carry out vacuum aluminum-coatedly, can be coated with PVDC, thereby improve the adhesive force of its heat sealability, barrier and printing; PET also has boiling resistance, the low temperature resistant freezing property of good heat resistance, excellence, good oil resistivity and chemical-resistant etc., be fit to various mechanical packagings, Manual Packaging, be widely used in the kink packing of candy, chocolate, dried beef, preserved fruit, delicatessen.PET film water absorption rate is low, water-tolerant, the food that the proper packing moisture is high.Because the PET film mostly is disposable use, along with abandoning in a large number after the use of PET film, the wasting of resources that causes thus and white pollution problems are day by day serious.How to effectively utilize this resource of waste PET film, it is reclaimed modification, preparation high-performance, plastic products have cheaply caused material engineering area research personnel's concern and attention.
Summary of the invention
Technical problem to be solved by this invention is, provides a kind of waste PET to make non-woven fabrics craft, it is characterized in that, may further comprise the steps:
(1) with the PET film crushing and the drying that reclaim;
(2) PET after the pulverizing stirs, and adding ethene-sad copolymer stirs into mixed material;
(3) mixed material is dropped into the double screw extruder extrusion plasticizing and become particle;
(4) plasticized granule is dropped into spinning manifold;
(5) material after the spinning becomes the net hot rolling.
Further, temperature dry in the step (1) is 130 ~ 150 ℃, and be 3 ~ 5h drying time.
Further, the rotating speed that mixes in the step (2) is 200 ~ 300r/min, and temperature is 100 ~ 110 ℃.
Further, the temperature of double screw extruder is respectively in the step (3): 190 ℃ in a district, and 210 ℃ in two districts, 230 ℃ in three districts, 240 ℃ in four districts, 250 ℃ in 5 districts, 260 ℃ in 6 districts, die head temperature is 260 ℃.
Further, spinning temperature is 310 ℃ in the step (4).
Further, hot-rolled temperature is 250 ℃ in the step (5).
Implement the present invention, have following beneficial effect: the present invention has utilized PET intensity characteristics high, good rigidly to produce solid durable nonwoven fabric, provide a kind of method easily and effectively for processing pet waste simultaneously, reduced environmental pollution and saved simultaneously production cost.
