The production process includes: 1, pretreatment of the bottle chips, 2, re-granulation and 3, melt spinning. Waste plastic bottles are adopted as raw materials, and short fibers which can be used for high-grade textile core materials are obtained through a method of re-granulation prior to spinning; the produced core materials are high in quality and have good market application, production cost is lowered, and effect of environmental protection and energy conservation is achieved.
Description
Technical field:
The present invention relates to produce the method for weaving core material, be specifically related to a kind of discarded bottle sheet stock that reclaims and produce the new method of weaving with core material.
Background technology:
PET is mainly that the production of manufacturing packing container and film, the especially beverage bottles such as beverage, food is greatly developed in recent years in the application in non-fine field.According to incompletely statistics, within 2004, the whole world approximately has 300,000 ~ 400,000 tons of PET to be used to the production of beverage bottle, beverage hot filling PET bottle exceedes 11,000,000,000, and its consumption figure is with annual 10% speed rapid growth, has also brought thus the white pollution of waste PET bottle generation.Therefore, from saving the angle of the energy and resource, protection of the environment, to using the recycling of rear PET bottle to become the problem of international community growing interest.According to statistics, the average recovery utilization rate of PET bottle is 20.4%, the high country of recovery utilization rate as Switzerland, Germany and Japanese philosophy be 100%, 49% and 46%, and China is only 1.7%.China for the utilization of discarded bottle sheet stock mainly in following purposes, as: Chinese patent application publication number is 200610157145: utilize the production technology of polyester returnable bottle production food-grade polyester bottle slice, Suzhou City Kechuang Polymer Co., Ltd. has developed a kind of technique of utilizing waste gas bottle chips production anti-flammability film trap material.Along with the recycling of waste gas bottle chips is worth the attention that day by day causes people, produce polyester filament, the invention report of functional fiber also proposes successively, for example: patent application publication number CN1355336A: the production technology of porous copolyester wadding from recovered bottles; The polyester bottle sheet material that utilizes that Foochow Heng Li chemical fibre Co., Ltd proposes is produced the method for fire-retardant staple fibre, and Shandong dragon good fortune ring can scientific and technological limited company be produced the method for polyester filament at the waste gas bottle chips that utilizes of latest report in 2011.
But its inherent viscosity after the direct extruding pelletization of PET bottle sheet of recovery can be significantly reduced to 0. 4 ~ 0. 5 dL/g.This is because PET bottle sheet residual certain moisture of meeting in cleaning process, in extrusion, very easily there is hydrolysis and pyrolysis, cause its strand to rupture, relative molecular mass can significantly reduce and embrittlement easy fracture, and its mechanical property is difficult to meet application requirements.And industrial PET pellet, even if require very low textile fabric or film all to require higher than 0. 6 dL/g by the inherent viscosity of PET.For this reason, can adopt reaction tackify method to improve its relative molecular mass, to reach higher inherent viscosity.---spinning that screw rod melt extrudes---level is filtered---that but most of polyester slice tackify spinning techniques are: dry.Its operation is many, and cost is high, consumes the bulk petroleum energy, can not fine embodiment reclaim the economic worth that discarded bottle sheet stock brings, and can not embody the environmental protection of energy-saving and emission-reduction simultaneously and advocate.
Summary of the invention:
The object of this invention is to provide a kind of production technology of utilizing discarded bottle sheet stock to produce the high-grade core of weaving; it can be by script inherent viscosity only for the polyester slice of 0.4-0.5dL/g be promoted to 0.8-1.1dL/g; can be for the production of for the higher long filament of requirement of strength; the core material quality of producing is outstanding; there is good market application foreground to reduce production costs simultaneously, and play the effect of the protection of the environment saving energy.
