Embodiment Construction

[0015] The present invention will be described in detail below in combination with specific embodiments.

[0016] A production process of polyester fiber filler, comprising the following steps,

[0017] (1) Material selection: Polyester recycled materials are used as raw materials for polyester fiber fillings, specifically polyester-containing plastic beverage bottles or pure polyester cloth scraps.

[0018] (2) Grinding and granulating, 1 ton of raw materials that have been artificially screened are broken into pieces with a diameter of 2-10 cm with a plastic pulverizer, and then added to a plastic granulator for granulation. The temperature is about 250°C during granulation. The finished granule diameter is between 0.2-2 cm.

[0019] (3) For pre-spinning, put the polyester return particles that have been pulverized and granulated into a drum dryer for drying and dehydration treatment. During the treatment, the drum is heated to about 140°C-160°C and dried continuously for 8...

Abstract

The invention relates to the field of stuffing for clothing and home textile industry. A production technique of polyester fiber stuffing comprises the steps of sorting, grinding and pelleting, pre-spinning and post-spinning, a PET chain extender and a color matching master batch dedicated to polyester are added in the pre-spinning process, and a polyester chopped fiber oiling agent is added in the post-spinning process. The polyester fiber stuffing produced by the production technique of the invention is not only low in cost but also can achieve the performance of the polyester fiber stuffing produced by fresh material in terms of resiliency, color, antistatic property, flexibility and cohesive property.

Description

technical field [0001] The invention relates to the field of fillers used in clothing and home textile industries, in particular to a process for producing polyester fiber fillers by using recycled polyester polyester. Background technique [0002] At present, there are mainly two production methods of using polyester fibers as fillers in the clothing and home textile industries in the market. One is to produce polyester staple fibers by melt-spinning method, which is produced with new materials, and the cost is relatively high; Using clothing waste to process again, the main product is black heart cotton, and its production process is to directly flower and process clothing waste with a flowering machine. Because the production process of black heart cotton is simple and without high temperature treatment, it contains a large amount of bacteria and harmful substances. Clothing made of this material will make the skin itchy and cause harm to the human body when it comes into...
