Embodiment 1

[0038] A method for preparing a knitted fabric with a biomimetic composite structure, the steps of which are:

[0039] (1) Design the organizational structure of the knitted fabric: the area of ​​the main area is four times the sum of the areas of the local areas, and the percentage of the area of ​​each local area in the sum of the area of ​​the local areas is 20%; the main area is a single-sided structure 1, scattered Multiple local areas in the main body area are double-sided structures 3; each local area is rhombus, specifically as figure 1 As shown, each local area is surrounded by a mesh structure 2, and the area of ​​the mesh structure accounts for 1.5% of the total area of ​​the knitted fabric;

[0040] (2) Weaving: computerized flat knitting machine is used for weaving, and the machine number of computerized flat knitting machine is 18; 300D / 36f DTY polyester filament is used to weave the main area and local area; weaving is from top to bottom, after the last row is w...

Embodiment 2

[0058] A method for preparing a knitted fabric with a biomimetic composite structure, the steps of which are basically the same as in Example 1, except that the knitted fabric is obtained without the hydrophilic and hydrophobic finishing in step (3), and the performance test results of the knitted fabric: moisture absorption speed The dry performance is shown in Table 1, and the air and moisture permeability performance is shown in Table 3.

[0059] Comparing Example 1 with Example 2, it can be seen that the moisture absorption and quick-drying performance and air and moisture permeability of Example 2 are lower than that of Example 1. This is because the inner layer of the single-sided structure, the double-sided The inner layer of the structure, the outer layer of the single-sided structure and the double-sided structure are finished differently, forming a hydrophilic-hydrophobic gradient on the surface of the fabric, which is conducive to the collection of liquid in the inne...

Embodiment 3

[0066] A method for preparing a knitted fabric with a bionic composite structure, the steps of which are basically the same as in Example 2, except that the shape of the local area is snowflake-shaped, and the area of ​​the main area is 2.9 times the sum of the areas of the local areas. The area of ​​the region accounts for 50% of the sum of the areas of the local areas, and each local area is surrounded by a mesh structure, and the area of ​​the mesh structure accounts for 2.4% of the total area of ​​the knitted fabric, such as figure 2 As shown, the knitting process is basically the same as in Example 1, except that the machine number of the computerized flat knitting machine used is 16, and in step (2.1), in the double-sided structure, the needle selection device of the flat knitting machine head is controlled At the same time, select the knitting needles of some needle beds I and II, and control the knitting needles of the needle bed I to do knitting in a circle by pulling...

Abstract

The invention relates to a preparation method of knitted fabric with a bionic composite structure. The preparation method comprises the step of knitting by using a computerized flat knitting machine after designing the organization structure of the knitted fabric, wherein the main body area of the knitted fabric is of a single-sided structure, a plurality of local areas dispersed in the main bodyarea are of double-sided structures, and the coil density of the single-sided structure, the coil density of the outer layers of the double-sided structures and the coil density of the inner layers ofthe double-sided structures are sequentially decreased; when knitting begins, the double-sided structure is knitted firstly, specifically, a needle selection device of the flat knitting machine headis controlled to select knitting needles of a front needle bed and a rear needle bed at the same time, meanwhile, the knitting needle of the needle bed I is controlled to perform looping knitting every other drawing needle, and the knitting needle of the needle bed II is controlled to firstly perform drawing needle looping and then perform tucking for 0-3 times on the same knitting needle of the needle bed I; and the knitting process of the single-sided structure comprises the steps of controlling the needle selection device of the flat knitting machine head to only select the knitting needleof the needle bed I to perform full-needle knitting, and controlling the knitting needle of the needle bed II not to perform knitting. The fabric prepared by the method is light, thin and good in one-way moisture conductivity.

Description

technical field [0001] The invention belongs to the technical field of textiles and relates to a method for preparing knitted fabrics with a bionic composite structure. Background technique [0002] With the diversification of lifestyles, people's requirements for clothing comfort are getting higher and higher. In order to keep the human body as comfortable as possible when wearing clothing in the state of sweating, it is required that the clothing worn has the performance of "moisture-wicking and quick-drying", that is, it can absorb sweat and quickly transfer sweat from the inner layer close to the skin To the outer layer of the garment, it evaporates quickly on the surface of the garment. At present, fabrics with moisture-wicking and quick-drying functions mainly use differential effects, select high moisture-wicking materials, and scientifically design fabric structures to obtain moisture-wicking and quick-drying properties. [0003] Knitted fabrics in the prior art ar...
