Description

Technical Field

[0001] The present application relates to the technical field of textile fabrics, and in particular to a nylon-spandex cool, quick-drying, comfortable fabric and a preparation method thereof. Background Art

[0002] As people's requirements for the comfort of sportswear increase, traditional fabrics can no longer meet the multiple needs of modern consumers for coolness, quick drying and comfort in the hot summer. Nylon-spandex fabrics have excellent elasticity, wear resistance and good moisture absorption and perspiration wicking properties. They can adapt to various movements without feeling restrained. They are soft and comfortable, smooth in contact with the skin, strong and durable, and not easy to break or pill. They are widely used in clothing and other fields.

[0003] Quick-drying fabrics are usually easy to care for and dry quickly after washing, making them convenient for daily use. However, existing quick-drying fabrics on the market often ignore wearing comfort and coolness, and cool fabrics generally lack quick-drying properties. Therefore, it is necessary to provide a fabric that combines coolness, quick drying and comfort. Summary of the invention

[0054] Performance testing (1) Select GB / T 35263-2017 Testing and evaluation of instantaneous coolness of textiles as the standard, and test and record the instantaneous coolness value q of the sample. max Three samples of 20cm*20cm were cut from each sample, and each sample was tested three times. The average value was taken after measurement and the results were recorded in Table 1.

[0055] (2) GB / T 21655.1-2023 Evaluation of moisture absorption and quick-drying properties of textiles Part 1: Single combination test method was selected as the standard to test the water absorption, wicking height, evaporation rate and moisture permeability of the test samples. Three samples were prepared for each sample, and the average value was taken after measurement. The results are recorded in Table 1.

[0056] (3) GB / T12703-1991 Textile Electrostatic Test Method was selected as the standard, and the C method charge surface density method was used for testing. Two pieces were randomly sampled from the warp and weft directions, and the charge surface density was calculated.

[0057] Table 1 Test results of cool feeling performance, quick drying performance and antistatic performance of nylon-spandex fabric As shown in Table 1, the q of Examples 1-3 max Greater than 0.351J / cm 2 .s, wicking height greater than 189mm / 30min, evaporation rate 0.23g / h, moisture permeability greater than 11353g / (m 2 ·24h), the charge surface density is less than 1.2μC / m 2 It can be seen that the nylon spandex fabric prepared in this application has good cool feeling, quick drying performance and antistatic performance.

[0058] It can be seen from Table 1 that the only difference between Examples 4 and 5 and Example 3 is that the mass ratio of the cool core material, wall material and highly dispersed nano jade powder in Example 4 is 1:1.2:0.05, and the mass ratio of the cool core material, wall material and highly dispersed nano jade powder in Example 5 is 1:1.2:0.25. Compared with Example 3, the cool quick-drying performance and antistatic performance of Examples 4 and 5 are reduced; this is because the mass ratio of the cool core material, wall material and highly dispersed nano jade powder is not within the specified range. Too much or too little highly dispersed nano jade powder will affect the stability of the cool additive, and then affect the stability of the fabric, thereby reducing the cool quick-drying performance and antistatic performance.

[0059] As can be seen from Table 1, the only difference between Examples 6, 7, 8, and 9 and Example 3 is that when preparing the cooling aid in Example 6, the highly dispersed nano jade powder is replaced with nano jade powder, when preparing the cooling aid in Example 7, the cooling core material is replaced with phase change material and borneol, when preparing the cooling aid in Example 8, the cooling core material is replaced with peppermint oil, and when preparing the cooling aid in Example 9, aniline is not added to the wall material. Compared with Example 3, the cooling and quick-drying properties and antistatic properties of Examples 6, 7, 8, and 9 are reduced; this is because the synthetic components of the cooling aid are replaced, which affects the interaction and stability between the components in the cooling aid, the performance of the cooling aid is reduced, and then the performance of the fabric is reduced, thereby reducing the cooling and quick-drying properties and antistatic properties.

[0060] As can be seen from Table 1, the only difference between Examples 10 and 11 and Example 3 is that the mass ratio of isocyanoethyl methacrylate, polyethylene glycol and dodecyldimethylbenzyl ammonium chloride in Example 10 is 1:1.3:0.05, and the mass ratio of isocyanoethyl methacrylate, polyethylene glycol and dodecyldimethylbenzyl ammonium chloride in Example 11 is 1:1.3:0.3. Compared with Example 3, the cool and quick-drying performance and the antistatic performance of Examples 10 and 11 are both reduced; this is because the mass ratio of isocyanoethyl methacrylate, polyethylene glycol and dodecyldimethylbenzyl ammonium chloride is not within the specified range, and too much or too little dodecylmethylpropyl ammonium chloride will affect the stability of the quick-drying auxiliary agent, thereby affecting the moisture absorption and perspiration performance of the fabric and the conductive performance of the fabric, thereby reducing the cool and quick-drying performance and the antistatic performance.

[0061] As can be seen from Table 1, the only difference between Example 12 and Example 3 is that dodecyl dimethyl benzyl ammonium chloride is not added when preparing the quick-drying auxiliary agent in Example 12. Compared with Example 3, the cool quick-drying performance and the antistatic performance of Example 12 are both reduced; this is because dodecyl dimethyl benzyl ammonium bromide is not added, the introduction of quaternary ammonium salt is lacking, the conductive performance is reduced, the evaporation rate of water is affected, the quick-drying performance of the fabric is reduced, and thus the cool quick-drying performance and the antistatic performance are reduced.

[0062] As can be seen from Table 1, the only difference between Comparative Example 1 and Example 3 is that no cooling agent is added in Comparative Example 1. Compared with Example 3, the cooling quick-drying performance and the antistatic performance of Comparative Example 1 are significantly reduced; this is because without adding a cooling agent, the heat storage and cooling of the phase change material and the cool feeling provided by peppermint oil and borneol are lacking, the cooling performance is greatly reduced, and at the same time, the conductive effect of aniline is lacking, so the cooling performance and the antistatic performance are significantly reduced.

[0063] As can be seen from Table 1, the only difference between Comparative Example 2 and Example 3 is that no quick-drying aid is added to Comparative Example 2. Compared with Example 3, the cool quick-drying performance and the antistatic performance of Comparative Example 2 are significantly reduced; this is because the moisture absorption and perspiration performance is reduced without adding the quick-drying aid, and at the same time, the lack of the introduction of quaternary ammonium salt reduces the conductive performance, thereby significantly reducing the quick-drying performance and the antistatic performance.

[0064] This specific embodiment is only an explanation of the present application, and it is not a limitation of the present application. Through the above description, relevant staff can make various changes and modifications without deviating from the technical idea of ​​the present application. The technical scope of the present application is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
