Problems solved by technology

However, in terms of material cost, due to various factors such as GRS certification, the quotation of recycled nylon fiber provided by the market is much higher than that of virgin nylon fiber
Moreover, the application of existing regenerated nylon fibers is difficult to produce other additional wearing experience for consumers, which makes it difficult for the shoe and apparel manufacturing end to promote the application on a large scale

preparation example Construction

[0031] The embodiment of the present invention provides a preparation method of functional regenerated nylon 6 fiber, comprising the following steps:

[0032] Nylon 6 waste is regenerated and granulated after pretreatment to obtain regenerated nylon granules;

[0033] The regenerated nylon particles are optionally mixed with additives, and then melt-spun. The melt-spun process adopts a flat inline spinneret to obtain functional regenerated nylon 6 fibers.

[0034] In the embodiment of the present invention, the recycled nylon waste is first regenerated and granulated, and the process route is as follows: nylon waste collection-crushing-cleaning-drying-granulator extrusion-cooling granulation-cutting.

[0035] Wherein, the nylon waste mainly adopts leftover material and waste in the production process of nylon 6. In the present invention, a crusher can be used to crush (or crush) the collected nylon waste, and the output is generally fragments of 2cm-3cm. The pretreatment pro...

Embodiment 1

[0048] 1. Regranulation of recycled materials:

[0049] Nylon 6 waste is regenerated and granulated, and the process route is as follows: nylon waste collection-crushing-cleaning-drying-granulator extrusion-cooling granulation-cutting. Among them, the nylon waste is leftover material and waste in the production process of nylon 6.

[0050] The collected nylon 6 waste is crushed by a crusher, and the output is 2-3cm fragments. The debris is cleaned in the primary washing tank to remove most of the dust, silt and other impurities mixed in the waste, mixed by the mixer, and then enters the centrifuge for dehydration after the first cleaning and the second cleaning, and then enters the dryer Drying, drying temperature 80-90 ℃.

[0051] The dried fragments (the raw materials after the above treatment maintain more than 95% of the weight before treatment, and the above treatment is mainly physical treatment) enter the twin-screw wire drawing machine from the feed port of the granu...

[0074] Nylon 6 waste is regenerated and granulated, and the process route is as follows: nylon waste collection-crushing-cleaning-drying-granulator extrusion-cooling granulation-cutting. Among them, the nylon waste is leftover material and waste in the nylon production process.

[0075] The collected nylon 6 waste is crushed by a crusher, and the output is 2-3cm fragments. The debris is cleaned in the primary washing tank to remove most of the dust, silt and other impurities mixed in the waste, mixed by the mixer, and then enters the centrifuge for dehydration after the first cleaning and the second cleaning, and then enters the dryer Drying, drying temperature 80-90 ℃.

[0076] The dried fragments enter the twin-screw wire drawing machine from the feed port of the granulator (the diameter of the screw is 35mm, the ratio of length to diameter is 36:1). : 230-235°C; second stage temperature: 277-232°C; third stage temperature:...

Abstract

The invention relates to the technical field of recycled nylon fibers, and provides a functional recycled nylon 6 fiber, a preparing method thereof and fabric. The functional recycled nylon 6 fiber isformed by nylon 6 waste through pre-treatment, recycling granulation and spinning in sequence, the a functional recycled nylon 6 fiber is provided with a flat straight-line section, the fiber is madeof the nylon waste, and has the environment friendliness, the special-shaped section structure of the recycled nylon 6 fiber can change the contact form of the fiber surface and water molecules, therefore, the property of the final fabric on continuous cool sense wearing experiences is improved, popularization and application are facilitated, in addition, zinc oxide is added in to the fiber, thefiber has the anti-bacterial function, meanwhile, a tracking element-barium used for source tracing is added, and source tracing tracking managing and controlling of the material from the fiber to a final garment finished product is facilitated.

Description

technical field [0001] The invention relates to the technical field of regenerated nylon fibers, in particular to a functional regenerated nylon 6 fiber, its preparation method and fabric. Background technique [0002] Nylon materials are widely used in clothing, automobiles, fishing gear, building materials and other fields, which are closely related to people's daily life, and thus produce a large amount of nylon waste materials. At the same time, the raw materials for synthetic nylon usually come from non-renewable petroleum resources. With the depletion of petroleum resources and the enhancement of global environmental protection awareness, people have begun to invest in research on various recycled nylon technologies. [0003] The so-called regenerated nylon is mainly obtained by recycling waste nylon materials such as waste fishing nets and waste carpets, undergoing physical and chemical treatment, depolymerization, removal of impurities, and then polymerization to obt...
