Problems solved by technology

[0002] PET materials are used in a large amount in the production of beverage, food and other packaging containers and films, especially the consumption of beverage bottles and mineral water bottles is increasing year by year, used beverage bottles and mineral water bottles will cause a lot of waste plastics, and plastic The natural degradation is very slow, and it is more suitable for recycling. The use of waste plastic bottles to produce short fibers is a good way to solve the pollution of waste plastics. At present, the production process of using waste plastic bottles to produce short fibers has been initially formed. , for example, the patent application publication number is CN201210556714 - a kind of production process of using discarded bottle flakes to produce high-grade textile core materials. The short fibers produced by the existing production process have poor resilience. When used as clothing textile raw materials, The body surface does not feel soft and uncomfortable when worn, which is not conducive to the market reputation of short-fiber clothing, and will eventually affect the development of short-fiber production of waste plastic bottle flakes

Embodiment Construction

[0022] The production process of utilizing PET plastic bottle flakes to produce differentiated polyester staple fibers related to the present invention, the production process comprises the following steps:

[0023] a. Bottle flake pretreatment: first clean the bottle flake raw material, then dry it with a dryer, and then color match and mix the clean bottle flakes as required. It is used in the production of fabrics or home textiles and their fillings When the short fiber is used, the blue and white clean bottle flakes are mixed, and the blue clean bottle flakes account for 15% to 20% by weight. When producing short fibers used in toy fillings, other colors of clean bottles are used. Tablet mixing ratio;

[0024] b. Spinning bottle flakes: first dry the clean bottle flakes with a good ratio. The working temperature of the extruder is 280-300 degrees Celsius;

[0025] c. Winding into barrel: spray oil on the extruded tow, and then wind the tow after oil injection. The speed ...

Abstract

The invention relates to a production process for producing differentiated polyester staple fibers by using PET plastic sheets. The production process includes the steps of bottle sheet pre-treatment, bottle sheet spinning and winding, drafting, tension heat setting, curling, relaxation heat setting, cutting and packaging, and inspection and warehouse entering. In the tension heat setting, heating rollers which are distributed in two layers in a staggered manner, wherein the upper layer includes nine heating rollers, and the lower layer includes eight heating rollers. The bottle sheet preprocessing step further comprises a color proportioning process of the bottle sheets. According to the color proportioning process of the bottle sheets, when staple fibers for clothes and home textiles are produced, blue and white net bottle sheets are adopted, while staple fibers for the fillers of toys are produced, net bottle sheets in other colors are adopted. The staple fibers produced by adopting the production process are soft and have high resilience. When contacting products made of the staple fibers, people can feel comfortable. The products made through adopting the production process have a bright market prospect.
