(1) weaving, namely weaving the fabric into grey cloth;
(2) and (4) dyeing and finishing, namely sequentially carrying out blank fixing → dyeing → dry cloth → shearing → fixing → inspection on the grey cloth obtained in the step S2 to obtain the perspiration ultra-soft and soft air layer fabric.
Preferably, the preparation method of the perspiration 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-position double-sided circular knitting machine, and cotton wool is aligned and woven into a weight per gram of 200-240 g/m2The air layer grey cloth;
s2 embryo determination: setting the grey cloth obtained in the step S1 at 200-240 ℃ for 30-60S to obtain pre-set grey cloth;
s3 staining: soaking the pre-shaped gray fabric obtained in the step S2 in an aqueous solution of sodium hydroxide, refining to remove oil for 15-30 min, and then taking out and naturally drying to obtain a pre-treated gray fabric; placing the pre-treated grey cloth into dyeing and finishing treatment liquid at 30-50 ℃, heating to 120-130 ℃ in a two-stage heating mode, and preserving heat for 20-40 min to obtain a system I; cooling the system I to 70-90 ℃ and keeping the temperature for 15-30 min, and adding sodium hydrosulfite and sodium carbonate during the period; obtaining a system II; cooling the system II to 40-60 ℃, adding a hydrophilic softening agent and citric acid, and keeping the temperature for 20-40 min;
s4 dry cloth: fishing out the cloth processed by the S3, cleaning the cloth with water, and drying the cloth at 60-80 ℃;
s5 shearing: performing single-side shearing treatment on the cloth obtained in the step S4;
s6 sizing: and (5) scutching and shaping the fabric obtained in the step (S5), and obtaining the perspiration super-soft and light elastic air layer fabric after qualified product inspection.
The air layer fabric with the multi-layer air layer structure is formed by mixed weaving, 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 demand on the perspiration property of the fabric. The inventor finds out through research that the processes of moisture conduction and perspiration of the air layer fabric mainly comprise wetting, moisture absorption, diffusion and evaporation, and particularly utilizes the capillary effect of the fabric to quickly transfer sweat sent out by a human body to the surface of the fabric for evaporation in the modes of absorption, transfer, diffusion and the like. The change of the fabric weaving mode and the addition of functional substances are the most common modes for improving the moisture-conducting and sweat-releasing performance of the fabric. According to the invention, on the basis of weaving a plurality of air layers, the fabric is soaked in the modifying solution, so that the moisture-conducting and sweat-releasing performance of the fabric is improved. The improvement of the hydrophilicity of the fabric is one of effective ways for improving the moisture permeability and perspiration performance 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 modification of textiles.

Test example 1
The softness of the fabric belongs to one aspect of fabric hand feeling, and is a subjective feeling when a person touches and grasps the fabric. The softness can be divided into rigidity and softness, the rigidity and softness mainly reflect the difficulty of the fabric in bending deformation, and the softness is realized when the fabric is easy to bend and deform, otherwise, the softness is rigid; the softness mainly reflects the difficulty of compression deformation of the fabric, and the fabric is soft when the fabric is easy to be compressed and deformed, and is hard otherwise. Therefore, the softness of the fabric is directly reflected by the difficulty of deformation, and the drapability test reaction of the fabric can be used. According to the standard GB/T23329-. The results are shown in table 1, where the lower the static drape coefficient of the data, the better the drape performance, and the softer the reactive fabric.
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 in table 1, it can be seen that compared to comparative example 1 without zinc oxide treatment, the softness of comparative example 2 is improved, and the softness of the fabric is improved probably because the zinc oxide has certain interaction with the fibers, reducing the friction between the fiber bundles. Example 3 in the modification process of the fabric, a pretreatment operation is added, and calcium formate and N- (2-aminoethyl) -3-aminopropyltrimethoxysilane are added, so that a silica space network structure can be formed to modify the fiber surface of the fabric, and the interaction between zinc oxide and the surface of the fabric is enhanced. Therefore, the softness of the fabric is further improved. The fabric of example 4 has the best softness, probably because the triethylene hexaacetic acid is also added into the pretreatment liquid, the carboxyl is introduced, the tension of the fiber surface is reduced, and the interaction of zinc oxide and the fabric surface is obviously enhanced. Compared with the example 4, the softness of the fabric is greatly reduced because calcium ions of the pretreated fabric have a repulsive effect on the adsorption of zinc ions, so that the zinc oxide precursor is slowly formed, and the particle size of zinc oxide is refined.
Test example 2
Vertical wicking is commonly used to directly test the moisture absorption and transmission properties of the fabric. Reference standard GB/T21655.1-2008 "assessment of moisture absorption quick drying of textiles part 1: the single combination test method cuts a fabric sample to be tested 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 is contacted with the water surface, the height of water climbing through the capillary action of the fabric after 30min is measured, and the wicking height of the fabric in the weft weaving direction is tested. The results are shown in table 2, with higher wicking height indicating better moisture absorption 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 |
As can be seen from the test results in table 2, the moisture absorption of the fabric of example 4 is the best, which is probably because the fabric of example 4 has capillary pores, hydrophilic zinc oxide with smaller particle size, more hydrophilic groups, lower surface tension, and positive charge, and the fabric treated by calcium formate has good moisture absorption performance.
The fabric has good water absorption, and water is absorbed on the surface of the fabric immediately. Therefore, the underwater oleophobic property of the fabric is tested, and the surface performance of the fabric is reflected. The results are shown in table 3, the larger the contact angle is, the more difficult the fabric is to be wetted by oil, the better the oil repellency is, and the contact angle is more than 150 degrees, so that the reaction material has super oil repellency.
Table 3 underwater contact angle test results 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, reaching the superoleophobic rating. This is probably because the finer hydrophilic zinc oxide, more hydrophilic groups, lower surface tension significantly increases the oleophobicity of the material.
