阅读说明：本技术 一种纳米涤纶纤维的制作方法 (Method for manufacturing nano polyester fiber ) 是由 胡蓉蓉 于 2018-07-23 设计创作，主要内容包括：本发明提供一种纳米涤纶纤维的制作方法,经湿法或干法或干湿法制成,先把经过加工的无机抗菌剂与聚酯熔体在双螺杆挤出机中共混造粒,制成母粒后再与涤纶纤维共混纺丝,然后将纳米涤纶纤维制成生条,再按花式线生产工艺进行条混,由花式捻线机制成本发明产品。其主要优点是色泽鲜亮,具有无毒、耐洗涤、耐光照、耐高温、抗菌持久等特点,极大提高本产品的附加值。(The invention provides a method for preparing nano polyester fiber, which is prepared by a wet method or a dry and wet method, wherein processed inorganic antibacterial agent and polyester melt are mixed and granulated in a double-screw extruder to prepare master batches, then the master batches are mixed and spun with the polyester fiber, then the nano polyester fiber is prepared into raw strips, and the strips are mixed according to a fancy yarn production process, and the product is prepared by a fancy twisting machine. The main advantages are bright color, non-toxic, washing-resistant, illumination-resistant, high-temperature-resistant, and durable antibacterial, and greatly increases the added value of the product.)

1. A process for preparing the nano antibacterial polyester fibres includes such steps as preparing fancy yarn from nano antibacterial polyester fibres, wet or dry or wet-wet mixing, granulating the inorganic antibacterial agent and polyester melt in dual-screw extruder, preparing mother particles, mixing with polyester fibres, spinning, preparing raw strips from nano polyester fibres, mixing, twisting to obtain fancy yarn, and winding.

2. The method for manufacturing nano antibacterial polyester fiber fancy yarn according to claim 1, wherein nano antibacterial polyester fiber roving strips are used as decorative yarns to be fed and drawn, the decorative yarns are wrapped on the surface of core yarns, the core yarns are high-count combed yarns, and the fixed fancy effect is selected as the fixed fancy effect.

Technical Field

The invention relates to the field of textiles, in particular to a method for manufacturing nano polyester fibers.

Background

At present, along with the pursuit of people for comfortable and healthy life, the antibacterial, deodorant, bacteriostatic and deodorant functional fiber product is popular with consumers at home and abroad, and the textile is one of the main carriers in the spreading process of pathogenic bacteria. The antibacterial fiber has the function of inhibiting the bacterial reproduction on the fiber product. The specially designed antibacterial fiber can kill bacteria on the fiber product; for example, the main source of sweat odor in clothes is the decomposition products produced by the growth of inhabited bacteria, using sweat and dirt (sebum, dirt, etc.) as a nutrient source. By suppressing the growth of such bacteria, the generation of odor can be prevented.

Disclosure of Invention

The invention aims to provide a method for manufacturing nano polyester fibers.

The purpose of the invention is realized by the following technical scheme:

a product for making fancy yarn by using nano antibacterial agent and polyester fiber is produced by wet method or dry and wet method, which is the same with the production process of common fancy yarn;

the specific manufacturing method comprises the following steps: the method comprises the steps of firstly mixing and granulating processed inorganic antibacterial agents and polyester melts in a double-screw extruder, preparing master batches, then mixing and spinning with polyester fibers, then preparing nano polyester fibers into raw strips, carrying out strip mixing according to a fancy yarn production process, preparing nano antibacterial polyester fiber fancy yarns by a fancy twisting machine, and then spooling to reeling.

The average silver ion particle size of the nano silver-based antibacterial powder is only 20.165 nanometers, and the nano silver-based antibacterial powder can be uniformly distributed in a product, so that no special requirements are required on the processing technology. The antibacterial agent is neutral in water, insoluble in water and organic solvents, resistant to acid, salt and weak base, good in heat and light stability, capable of destroying microbial activity by contact reaction, and lasting in antibacterial effect, and the antibacterial component is silver ions; meanwhile, under the action of light, the silver ions can play a role of catalyzing active centers, activate oxygen in water and air and generate active oxygen ions, and the active oxygen ions have strong oxidizing capacity and can destroy the proliferation capacity of bacteria in a short time to cause cell death, so that the aim of resisting bacteria is fulfilled.

The product manufactured by the invention has the beneficial effects that fancy yarn woven by the nano antibacterial polyester fiber is bright in color, has the characteristics of no toxicity, washing resistance, illumination resistance, high temperature resistance, lasting antibiosis, deodorization and the like, and greatly improves the added value of the product.
