Description

Technical Field

[0001] The invention belongs to the technical field of fabrics, and in particular relates to a moisture-absorbing quick-drying wool composite fabric and a preparation method and application thereof. Background Art

[0002] Wool fabrics are soft, have good moisture absorption and air permeability. In the prior art, knitted fabrics with a high wool content generally only have basic moisture absorption properties and do not have the characteristic of quick drying. This is because wool fibers contain many hydrophilic groups that will tightly bind to water molecules, and wool fibers have a scale layer, and the movement speed of water molecules inside and on the surface of the fibers is slow. When the wool fabric absorbs water, the water is not easy to quickly escape from the fabric, and it takes longer to dry. In the same humid environment, the moisture-absorbing and quick-drying fabrics of polyester, cotton and other fabrics may dry in a few hours, while wool fabrics may take a day or more to completely dry. And because the drying process takes too long, wool fabric clothes are easily deformed due to the influence of the hangers when they are hung on hangers.

[0003] Therefore, it is necessary to develop a moisture-absorbing and quick-drying wool composite fabric to enhance the user experience. Summary of the invention

[0004] In view of the deficiencies in the prior art, the object of the present invention is to provide a moisture-absorbing and quick-drying wool composite fabric and a preparation method and application thereof. The moisture-absorbing and quick-drying wool composite fabric has the functions of moisture absorption, quick drying and breathability.

[0005] To achieve this object, the present invention adopts the following technical solutions:

[0008] The wool composite fabric comprises wool composite fibers, and the wool composite fibers comprise shrink-proof wool, moisture-absorbing and breathable polyester fibers and nylon.

[0009] In the present invention, a wool composite fabric is prepared by compounding shrink-proof wool, moisture-absorbing and breathable polyester fiber and nylon, wherein the shrink-proof wool can provide good moisture absorption and quick-drying properties, but has poor moisture conductivity, the moisture-absorbing and breathable polyester fiber has moisture absorption, breathability and moisture conductivity, and the nylon has wear resistance and hydrophilic properties, which can improve the drip diffusion performance of the wool composite fabric; the three are compounded so that the wool composite fabric has the characteristics of shrink-proof wool, moisture-absorbing and breathable polyester fiber and nylon, and can complement each other; then the wool composite fabric is degreased, treated with a first moisture-absorbing and quick-drying auxiliary agent, dried, impregnated and heat-set to obtain the moisture-absorbing and quick-drying wool composite fabric, wherein the first moisture-absorbing and quick-drying auxiliary agent mainly plays a role in increasing the moisture absorption and air permeability of the moisture-absorbing and breathable polyester fiber, and the second moisture-absorbing and quick-drying auxiliary agent mainly plays a role in increasing the moisture conductivity of the shrink-proof wool and improving the drip diffusion rate, and the combination of the two makes the obtained moisture-absorbing and quick-drying wool composite fabric have excellent moisture absorption and quick-drying effect.

[0144] Comparative Example 1

[0145] This comparative example provides a moisture-absorbing and quick-drying wool composite fabric and a preparation method thereof, which differs from Example 1 only in that moisture-absorbing and breathable polyester fiber is not added in the preparation of the wool composite fabric, the mass percentage of nylon is adjusted to 40%, and other conditions are the same as those in Example 1.

[0146] Comparative Example 2

[0147] This comparative example provides a moisture-absorbing and quick-drying wool composite fabric and a preparation method thereof, which is different from Example 1 only in that a degreasing step is not included, and other conditions are the same as those of Example 1.

[0148] Comparative Example 3

[0149] This comparative example provides a moisture-absorbing and quick-drying wool composite fabric and a preparation method thereof, which is different from Example 1 only in that the padding liquid does not include a second moisture-absorbing and quick-drying auxiliary agent, and other conditions are the same as those of Example 1.

[0150] The moisture absorption and quick-drying wool composite fabrics provided in the above-mentioned Examples 1-9 and Comparative Examples 1-3 were tested for moisture absorption and quick-drying before washing in accordance with GB / T21655.1-2023, and then washed 5 times using the 4N program in accordance with GB / T 8629-2017, hung to dry, and then tested for moisture absorption and quick-drying after washing; if the moisture absorption and quick-drying before washing and the moisture absorption and quick-drying before washing can both meet the conditions of drip diffusion time ≤6s, water absorption rate ≥80%, wicking height ≥80mm and drying rate ≥0.20g / h, it is considered that the moisture absorption and quick-drying properties are good; if the moisture absorption and quick-drying before washing and the moisture absorption and quick-drying before washing can both meet the conditions of drip diffusion time ≤4s, water absorption rate ≥100%, wicking height ≥90mm and drying rate ≥0.30g / h, it is considered that the moisture absorption and quick-drying properties are good.

[0151] The test results are shown in Table 1 below:

[0152] Table 1

[0153]

[0154] It can be seen from the contents of Table 1 that the moisture-absorbing and quick-drying wool composite fabrics provided by Examples 1 to 9 have good moisture-absorbing and quick-drying properties both before and after washing.

[0155] Compared with Example 1, if the concentration of the first moisture absorbing and quick-drying auxiliary agent is too low (Example 4), the drying rate of the prepared moisture absorbing and quick-drying wool composite fabric is low, and can only barely reach 0.2 g / h; if the concentration of the first moisture absorbing and quick-drying auxiliary agent is too high (Example 5), the moisture absorbing and quick-drying effect of the prepared moisture absorbing and quick-drying wool composite fabric is not improved, but the cost is increased. It can be seen that the moisture absorbing and quick-drying wool composite fabric prepared by controlling the concentration of the first moisture absorbing and quick-drying auxiliary agent within a specific range has better performance.

[0156] Compared with Example 1, if the concentration of the second moisture absorbing and quick-drying auxiliary agent is too low (Example 6), the water drip diffusion time of the prepared moisture absorbing and quick-drying wool composite fabric after washing can barely reach 6s, and the water drip diffusion speed is slow; if the concentration of the second moisture absorbing and quick-drying auxiliary agent is too high (Example 7), the water absorption rate of the prepared moisture absorbing and quick-drying wool composite fabric is too high, resulting in a low drying rate. It can be seen that the moisture absorbing and quick-drying wool composite fabric prepared by controlling the concentration of the second moisture absorbing and quick-drying auxiliary agent within a specific range has better performance.

[0157] Compared with Example 1, if the mass percentage of the hygroscopic and breathable polyester fiber is too low and the mass percentage of nylon is too high (Example 8), the water absorption rate of the prepared hygroscopic and quick-drying wool composite fabric is relatively high, resulting in a low drying rate; if the mass percentage of the hygroscopic and breathable polyester fiber is too high and the mass percentage of nylon is too low (Example 9), the wicking height of the prepared hygroscopic and quick-drying wool composite fabric is relatively low.

[0158] Compared with Example 1, if the hygroscopic and breathable polyester fiber is not added (Comparative Example 1), the drying rate of the obtained hygroscopic and quick-drying wool composite fabric before and after washing is less than 0.2 g / h, and the hygroscopic and quick-drying property is poor.

[0159] Compared with Example 1, if the degreasing step is not included (Comparative Example 2), the oil stains during the weaving process will adhere to the fiber surface to form a water-repellent film, resulting in a long drip diffusion time of more than 6s, a low wicking height, and poor moisture absorption and quick-drying properties.

[0160] Compared with Example 1, if the second moisture absorption and quick-drying auxiliary agent is not included in the padding liquid (Comparative Example 3), the water diffusion time of the obtained moisture absorption and quick-drying wool composite fabric before and after washing is greater than 6s, and the moisture absorption and quick-drying property is poor.

[0161] The applicant declares that the present invention uses the above-mentioned embodiments to illustrate a moisture-absorbing and quick-drying wool composite fabric and its preparation method and application, but the present invention is not limited to the above-mentioned embodiments, that is, it does not mean that the present invention must rely on the above-mentioned embodiments to be implemented.
