Problems solved by technology

The production of functional textiles is mainly divided into two types: one is to use finishing technology to endow fabrics with some special functions, such as single-sided moisture-wicking fabrics, anti-ultraviolet fabrics, antibacterial fabrics, etc.; the other is to modify fibers treatment, such as antibacterial fiber, anti-ultraviolet fiber, etc. However, the durability of the special functional textile fiber prepared by the above method is not very good
It is necessary to develop new preparation methods for special functional textile fibers to solve the problems of low fiber durability and low fiber functional efficiency

preparation example Construction

[0024] The preparation method of the special functional textile fiber of the present invention, the special functional textile fiber includes a functional device and a polymer material fiber layer coated on the outer peripheral surface of the functional device, which includes the following steps: (a) making the polymer material into Prefabricated rod, processing the preformed rod to form a hollow cavity inside, filling the hollow cavity with functional material to form the functional device, and then sealing the end; or, after softening the polymer material and the functional device in the mold Composite, and extrusion molding to form the polymer material fiber layer on the outer peripheral surface of the functional device; (b) stretching the preform obtained in step (a) to obtain special functional textile fibers. In this way, the structural control of the distribution of functional materials can be carried out, which can effectively improve its functional effect, save functio...

Embodiment 1

[0030] This embodiment provides a preparation method of special functional textile fibers (conductive fibers), which includes the following steps:

[0031] (a) Using the existing technology, the PET material is extruded through a mold to produce a preform 20'', which has high transparency and is conducive to observing the distribution of its internal structure; the PET preform 20'' is drilled , grinding and other mechanical processing, so that the middle part forms a hollow structure (the diameter of the hollow structure is 1~2mm, such as figure 1 shown), and then fill it with conductive carbon powder (specific surface area 36 m 2 / g, specific resistance 2.3×10 -1 Ωm, specific gravity 1.8, particle size less than 25nm, purity 99.9%), compacted to form functional devices 10'', both ends sealed with resin;

[0032] (b) using such as image 3 The equipment shown is stretching and forming, specifically: the preform 20'' is fixed and sent to the furnace 1, and the temperature i...

Embodiment 2

[0034] This embodiment provides a kind of preparation method of special functional textile fiber (far-infrared health-care fiber), which comprises the following steps:

[0035] (a) Using the existing technology, the PET material is extruded through a mold to obtain a preform 20', which has high transparency and is conducive to observing the distribution of its internal structure; the PET preform 20' is drilled and polished and other mechanical processing, so that the middle part forms multiple hollow structures parallel to each other (the diameter of each hollow structure is 1~2mm, such as figure 2 shown), and then fill it with Taichi stone far-infrared powder (the particle size of Taichi stone powder is about 100nm; the preparation method is: calcinate Taichi stone minerals at about 1000°C, cool naturally and grind to obtain Taiji Far-infrared stone powder), compacted to form a functional device 10', and both ends are sealed with resin;

[0036] (b) using such as image 3 ...

Abstract

The invention relates to a preparation method of a special function textile fiber. The special function textile fiber comprises a functional device and a high polymer material fiber layer coating theperipheral face of the functional device. The method comprises the following steps that 1, a high polymer material is manufactured into a preform rod, the preform rod is processed so that a hollow cavity can be formed inside, and the hollow cavity is filled with a functional material to form the rear packaging end of the functional device; or, the high polymer material is composited with the functional device inside a mold after being softened, and after extrusion molding, the high polymer material fiber layer is formed on the peripheral face of the functional device; 2, the preform rod obtained in the step 1 is stretched to obtain the special function textile fiber. The functional material distribution can be structurally controlled, the function effect can be effectively improved, meanwhile, functional raw materials can be saved, and the cost is effectively lowered; the problems that an existing prepared fiber is not high in durability and low in functionality efficiency are solved.

Description
