Abstract
The invention relates to a preparation method of regenerated polyester (PET). The method is characterized by soaking, spin-drying and clustering the waste PET yarns to form PET particles with diameter within 1cm, mixing the PET particles with the ground PET bottle flakes in a weight ratio of 1:4 and stirring the mixture, then drying the mixture formed after mixing and stirring at the temperature of 180-200 DEG C until the moisture content is lower than 50ppm and finally melting and spraying the dried mixture, thus obtaining the regenerated PET. The preparation method has the following advantages: the preparation process is simple and easy to operate; and the quality and benefit of recycle of the PET plastic bottles and waste PET yarns are improved.
Description
[technical field]
The present invention relates to a kind of preparation method of textile raw material, relate in particular to a kind of preparation method of regenerated terylene.
[background technology]
In the waste recovery industry, usually PET plastic bottle such as the mineral water bottle of returning, beverage bottle and terylene waste all are that branch comes and handles separately.Wherein, the PET plastic bottle is through fragmentation, cleaning, high vacuum oven dry, the plasticizing of heating, wire drawing, cooling, granulation, the PET particle that generates after the processed, for making the PET Related product again, as textile of chemical fibre raw material, PET sheet stock, engineering plastics, regenerated plastics film, injection raw material etc.; Terylene waste has regenerating use more widely, except that regenerated silk is produced, also serves as the inner packing etc. that fuel, stuffing or alternative foamed plastic become some products.In recycling process, also do not occur with PET plastic bottle and terylene waste the two now and combine and use to obtain the method that a kind of overall quality is higher, bring the raw material of bigger recovery benefit to PET plastic bottle and terylene waste.
[summary of the invention]
Technical problem to be solved by this invention is to provide a kind of preparation method of regenerated terylene, and preparation process is simple, easy to operate, has improved the quality and the benefit that reclaim PET plastic bottle and terylene waste.
The present invention solves the problems of the technologies described above by the following technical programs: a kind of preparation method of regenerated terylene, and earlier terylene waste being placed temperature is that 50～60 ℃ water soaks 1h, and wash away grease, with supercentrifuge it is dried again; Terylene waste after then will drying is pulverized, and adopts the machine of uniting that it is united forming the terylene particle afterwards, is in the 1cm until the diameter of this terylene particle; Get this terylene particle and mix stirring by 1: 4 weight ratio, will mix then and stir mixture that the back forms and place under 180～200 ℃ of conditions and dries, be lower than 50 ppm until the content of its moisture with PET bottle sheet after fragmentation; At last the mixture after this oven dry is passed through melt-out spinning, then obtain described regenerated terylene.
The preparation method's of a kind of regenerated terylene of the present invention beneficial effect is: adopting PET plastic bottle and terylene waste is that feedstock production goes out a kind of new regenerated terylene, this regenerated terylene can be used for making shoestring and knapsack shoulder belt etc. and the non-textiles that directly contacts of human skin, also provides a kind of new raw material sources for textile industry when improving PET plastic bottle and terylene waste recovery quality and benefit; In addition, simple, the easy operating of this method preparation process, large, medium and small type enterprise all can prepare.
[specific embodiment]
The preparation method of a kind of regenerated terylene of the present invention, mainly be different according to the two viscosity of PET plastic bottle and terylene waste, consider from the complementary aspect of viscosity, the two is prepared recovery quality high product by certain proportioning, it is as follows that it has operation: earlier terylene waste being placed temperature is that 50～60 ℃ water soaks 1h, and wash away grease, with supercentrifuge it is dried again; Terylene waste after then will drying is pulverized, adopt the machine of uniting that it is united to form the terylene particle afterwards, diameter until this terylene particle is that 1cm is not with interior (the terylene particle that forms of uniting after even once pulverizing reaches this requirement, then need carry out secondary and pulverize); Get this terylene particle and mix stirring by 1: 4 weight ratio, will mix then and stir mixture that the back forms and place under 180～200 ℃ of conditions and dries, be lower than 50 ppm until the content of its moisture with PET bottle sheet after fragmentation; At last the mixture after this oven dry is passed through melt-out spinning, then obtain described regenerated terylene.
For better the present invention will be described, the present invention is for following several embodiment.
Embodiment one
Adopt disintegrating machine to carry out fragmentation back formation PET bottle sheet with standby the PET plastic bottle of returning, meanwhile, it is that 50 ℃ water soaks 1h that terylene waste is placed temperature, and wash away grease, with supercentrifuge it is dried again; Terylene waste after then will drying is pulverized, and adopts the machine of uniting that it is united forming the terylene particle afterwards, is in the 1cm until the diameter of this terylene particle; Get this terylene particle and mix stirring by 1: 4 weight ratio, will mix then and stir mixture that the back forms and place under 200 ℃ of conditions and dries, be lower than 50 ppm until the content of its moisture with PET bottle sheet after fragmentation; At last the mixture after this oven dry by melt-out spinning to obtain described regenerated terylene.
Embodiment two
Adopt disintegrating machine to carry out fragmentation back formation PET bottle sheet with standby the PET plastic bottle of returning, meanwhile, it is that 55 ℃ water soaks 1h that terylene waste is placed temperature, and wash away grease, with supercentrifuge it is dried again; Terylene waste after then will drying is pulverized, and adopts the machine of uniting that it is united forming the terylene particle afterwards, is in the 1cm until the diameter of this terylene particle; Get this terylene particle and mix stirring by 1: 4 weight ratio, will mix then and stir mixture that the back forms and place under 180 ℃ of conditions and dries, be lower than 50 ppm until the content of its moisture with PET bottle sheet after fragmentation; At last the mixture after this oven dry by melt-out spinning to obtain described regenerated terylene.
Embodiment three
Adopt disintegrating machine to carry out fragmentation back formation PET bottle sheet with standby the PET plastic bottle of returning, meanwhile, it is that 60 ℃ water soaks 1h that terylene waste is placed temperature, and wash away grease, with supercentrifuge it is dried again; Terylene waste after then will drying is pulverized, and adopts the machine of uniting that it is united forming the terylene particle afterwards, is in the 1cm until the diameter of this terylene particle; Get this terylene particle and mix stirring by 1: 4 weight ratio, will mix then and stir mixture that the back forms and place under 190 ℃ of conditions and dries, be lower than 50 ppm until the content of its moisture with PET bottle sheet after fragmentation; At last the mixture after this oven dry by melt-out spinning to obtain described regenerated terylene.
The regenerated terylene that the various embodiments described above obtained all can be used for making shoestring and knapsack shoulder belt etc. and the non-textiles that directly contacts of human skin, for textile industry provides a kind of new raw material sources; Compared to PET plastic bottle and independent quality and the benefit that reclaims of terylene waste, this regenerated terylene has higher quality and benefit.
