Embodiment 1

[0035] A method for preparing a knitted fabric with a biomimetic composite structure, the steps of which are:

[0036] (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, scattered in Multiple local areas in the main area are double-sided structures; each local area is diamond-shaped, specifically as figure 1 As shown, the white area is the main area, and the black area is the local area;

[0037] (2) Knitting: Select a circle-moving rib computerized jacquard circular machine with a machine number of 18 needles, a tube diameter of 34 inches, and a number of 54 (including 36 loops forming loops and 18 loop transfer loops), and a total needle count of 3840. The needle is a latch needle, the number of needles is 1920, the lower needle is a tr...

Embodiment 2

[0056] 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.

[0057] Comparing Example 1 with Example 2, it can be seen that the moisture absorption and quick-drying performance of Example 2 is lower than that of Example 1. This is because the inner layer of the single-sided structure, the inner layer of the double-sided structure, The outer layers 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 inner layer of the fabric, that is, moving...

Embodiment 3

[0063] A method for preparing a knitted fabric with a bionic composite structure, the steps of which are basically the same as in Example 1, 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 area accounts for 50% of the sum of the areas of the local areas, such as figure 2 As shown, the white area is the main area, and the black area is the local area; the knitting process is basically the same as that of Example 1, except that in step (2.2), when the upper needle and the lower needle are knitted at the same time, the tuck of the lower needle The number of times is 1; in the performance test results of the knitted fabric: the moisture absorption and quick-drying properties are shown in Table 1, and the air and moisture permeability properties are shown in Table 3.

Abstract

The invention relates to a preparation method of a bionic composite structural knitted fabric. Since the stitch structure of the knitted fabric is designed, a circular weft knitting machine having a loop transferring function is adopted for knitting; the primary area of the knitted fabric is in a single-sided structure, a plurality of local areas distributed in the primary area are in double-sidedstructure, and the stitch density of the single-sided structure, the stitch density of the outer layer of the double-sided structure and the stitch density of the inner layer of the double-sided structure are decreased gradually; at beginning of the knitting, the double-sided structure is formed by purl stitch and knit stitch simultaneously, the purl stitch forms loop alternatively one by one, the knit stitch forms loop alternatively one by one, and the number of tucking of the knit stitch is 0-3; in the process of converting the knitting of the double-sided structure into the knitting of thesingle-sided structure, the purl stitch and knit stitch are selected as needed to perform the loop transferring motion, and by the loop transferring motion, the loops on the knit stitch are transferred to the position, at where there are no loops, on the purl stitch which forms loop alternatively, so as to form the single-sided structure; in the process of converting the knitting of the single-sided structure into the knitting of the double-sided structure, latches of needles of the purl stitch and the knit stitch are opened. The knitted fabric is light and thin and has good unidirectional moisture-guide effect.

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...
