In view of the defects of the prior art, the invention invents the sweat-discharging super-soft and light-elastic air layer fabric which has the advantages of soft hand feeling, light weight, good drapability, strong heat preservation performance, good hygroscopicity and quick drying.
In order to achieve the above purpose, the invention provides a preparation method of a sweat-releasing super-soft and light-elastic air layer fabric, which comprises the following steps:
(1) Weaving, namely weaving the fabric into grey cloth;
(2) Dyeing and finishing treatment, namely sequentially performing embryo fixing, dyeing, cloth drying, shearing, shaping and inspection on the gray fabric obtained in the step S2 to obtain the sweat-releasing super-soft and light-elastic air layer fabric.
Preferably, the preparation method of the sweat-releasing super-soft and light-elastic air layer fabric comprises the following steps:
s1, weaving: the Modal siro compact spinning, coolmax and high temperature resistant spandex are placed in a three-functional double-sided circular knitting machine, cotton wool is aligned and knitted into a yarn with the gram weight of 200-240 g/m 2 Is a blank of air layer;
s2, embryo fixing: setting the gray fabric obtained in the step S1 at 200-240 ℃ for 30-60S to obtain preset gray fabric;

According to the invention, the air layer fabric with a multi-layer air layer structure is formed through mixed knitting, so that the elasticity and softness of the fabric are maintained. The existing air layer fabric is mostly used for thermal underwear, and has great requirements on perspiration property of the fabric. The inventor finds that the moisture-conducting and sweat-releasing process of the air layer fabric mainly comprises wetting, moisture absorption, diffusion and evaporation, and particularly utilizes the capillary effect of the fabric to quickly transfer sweat sent by a human body to the surface of the fabric for evaporation in the manners of absorption, transfer, diffusion and the like. The change of the weaving mode of the fabric and the addition of functional substances are the most commonly used modes for improving the moisture-conducting and sweat-releasing performance of the fabric. On the basis of weaving a plurality of layers of air layers, the fabric is soaked in the modifying liquid, so that the moisture-conducting and sweat-releasing performance of the fabric is improved. Improving the hydrophilicity of the fabric is one of the effective ways to improve the moisture-conducting and sweat-releasing properties of the fabric. The zinc oxide nano particles can absorb water molecules, so that the zinc oxide nano particles have hydrophilicity and are widely applied to the modification of textiles.

Test example 1
Softness of the fabric belongs to one aspect of hand feel of the fabric, and is subjective feeling when a person touches and holds the fabric. Softness can be divided into hardness and softness, wherein the hardness mainly reflects the difficulty of bending deformation of the fabric, and the fabric is soft when bending deformation is easy, and otherwise, the fabric is rigid; the hardness mainly reflects the difficulty of the fabric in compression deformation, and the fabric is soft when easy to be subjected to compression deformation, and is hard when easy to be subjected to compression deformation. Therefore, the softness of the fabric is directly reflected by the difficulty of deformation, and the fabric drapability test reaction can be used. With reference to the standard GB/T23129-2009 "determination of drape of textile fabrics", cloth to be tested is cut into a circular sample with a diameter of 24cm, and the drape performance of the sample is tested by an XDP-1 fabric drape tester. The results are shown in Table 1, wherein the smaller the static drape coefficient of the data is, the better the drape performance is, and the softer the fabric is.
TABLE 1 drape performance results
| Static drape coefficient (%) | |
| Example 1 | 10.35 |
| Example 2 | 9.56 |
| Example 3 | 7.32 |
| Example 4 | 5.63 |
| Comparative example 1 | 7.45 |
From the test results of table 1, it can be seen that the softness of comparative example 2 is improved over comparative example 1 which is not treated with zinc oxide, and the softness of the fabric is improved because zinc oxide has a certain interaction with the fibers, so that the friction between the fiber bundles is reduced. Example 3 a pretreatment operation was added during the modification of the fabric, and calcium formate, N- (2-aminoethyl) -3-aminopropyl trimethoxysilane, was added to form a modification of the silica space network structure on the fiber surface of the fabric, enhancing the interaction of zinc oxide with the fabric surface. Therefore, the softness of the fabric is further improved. The fabric of example 4 has the best softness, probably because triethylenetetramine hexaacetic acid is also added into the pretreatment liquid, carboxyl groups are introduced, the tension of the fiber surface is reduced, and the interaction between zinc oxide and the surface of the fabric is remarkably enhanced. Comparative example 1 was not added with calcium formate compared to example 4, and the softness of the fabric was greatly impaired, probably because the pretreated fabric had a repulsive effect on the adsorption of zinc ions by calcium ions, so that the formation of zinc oxide precursor was slower, and the particle size of zinc oxide was refined.
Test example 2
Vertical wicking is commonly used to directly test the absorbency and wet permeability of a fabric. Evaluation of moisture absorption and quick drying Properties of textiles section 1 with reference to Standard GB/T21655.1-2008: the single combined test method is that a fabric sample to be tested is cut into a strip shape of 10cm multiplied by 20cm, then one end of the sample is hung on an iron stand, the other end of the sample contacts the water surface, the height of water climbing by capillary action of the fabric after 30 minutes is measured, and the wicking height of the fabric in the weft knitting direction is tested. The results are shown in table 2, with higher wicking height indicating better absorbency of the facing.
Table 2 wicking height results
| Wicking height (cm) | |
| Example 1 | 5.68 |
| Example 2 | 7.38 |
| Example 3 | 8.26 |
| Example 4 | 10.34 |
| Comparative example 1 | 8.02 |
From the test results of table 2, it can be seen that the hygroscopicity of example 4 is the best, probably because the capillary holes, the hydrophilic zinc oxide with smaller particle size, the more hydrophilic groups, the lower surface tension, and the positive charge of the calcium formate treated fabric in the fabric of example 4, provided good hygroscopicity.
The fabric provided by the invention has good water absorbability, and water is immediately adsorbed on the surface of the fabric. Therefore, the underwater oleophobic property of the fabric was tested and the surface properties of the fabric were reacted. The results are shown in Table 3, the larger the contact angle, the more difficult the fabric is to be infiltrated by oil, the better the oleophobicity, and the more than 150 DEG of contact angle the reaction material has super oleophobicity.
Table 3 results of underwater contact angle test of fabrics
| Contact angle (°) | |
| Example 3 | 145.3 |
| Example 4 | 153.2 |
| Comparative example 1 | 139.6 |
From the results in Table 3, it can be seen that example 4 has the best oleophobic properties, achieving a super oleophobic grade. This is probably because finer hydrophilic zinc oxide, more hydrophilic groups, lower surface tension significantly improves the oleophobicity of the material.
