Description

Technical Field

[0001] The invention belongs to the technical field of fabrics, and in particular relates to a breathable, cool and comfortable fabric and a preparation method thereof. Background Art

[0002] Polyester fiber, also known as polyester fiber, is a type of synthetic fiber with excellent properties such as high modulus, good elasticity, shape retention and high heat resistance stability. It is widely used in clothing and household products. However, due to the dense stacking of polyester fiber macromolecules and high crystallinity, water molecules are difficult to penetrate and the hydrophilicity is very poor. It is a typical hydrophobic fiber with a moisture regain of only 0.4%-0.5% under standard conditions. When polyester fabric is worn in a hot and humid environment, due to its poor hydrophilicity and hygroscopicity, wet clothing easily sticks to the skin and produces a sticky and stuffy discomfort, which reduces the wearing comfort of the clothing. Its application in summer clothing, sportswear and casual wear is subject to certain restrictions. How to retain the excellent properties of polyester fiber itself and improve the moisture absorption and perspiration performance of the fabric is critical to improving the wearing comfort of polyester fabric and the wider application of polyester fiber.

[0117] Performance Testing

[0118] Test Example 1

[0119] Conduct air permeability test according to standard GB / T5453-1997;

[0120] Conduct cooling performance test according to standard GB / T 35263-2017;

[0121] The antibacterial performance test was carried out in accordance with the standard GB / T39104.2-2020.

[0122] The fabrics obtained in Examples 1-3 and Comparative Examples 1-6 prepared on the basis of Example 2 were subjected to performance tests according to the above standards. The test results are shown in Table 1 below:

[0123] Table 1

[0124]

[0125]

[0126] As can be seen from Table 1, the fabrics prepared in Examples 1-3 of the present application have excellent air permeability, a cool texture, and an antibacterial effect.

[0127] In Comparative Example 1, polyester-based coffee carbon fiber was not added, resulting in reduced air permeability and cooling performance; in Comparative Example 2, polyester-based coconut carbon fiber was not added, resulting in reduced air permeability and cooling performance; in Comparative Example 3, kiwano fiber was not added, resulting in reduced air permeability and cooling performance; this is because the materials of polyester-based coconut carbon fiber, polyester-based coffee carbon fiber, and kiwano fiber have excellent air permeability and cool texture, and the three synergistically improve the air permeability and cooling comfort performance of the fabric. The cool gel capsules in Comparative Examples 4-6 have almost no effect on the air permeability, but the fabric surface in Comparative Example 4 is not covered with gel capsules, resulting in a significant reduction in cooling. No peppermint oil was added in Comparative Example 5, and no berry tea extract was added in Comparative Example 6. The volatilization of peppermint oil and berry tea extract will take away heat due to the cooling effect, thereby improving the cooling performance of the fabric.

[0128] In addition, in terms of antibacterial properties, polyester-based coffee carbon fiber was not added to Comparative Example 1, resulting in reduced antibacterial properties; in Comparative Example 2, polyester-based coconut carbon fiber was not added, resulting in reduced antibacterial properties; in Comparative Example 3, caltrop fiber was not added, resulting in reduced antibacterial properties; this is because polyester-based coconut carbon fiber, polyester-based coffee carbon fiber, and caltrop fiber have certain antibacterial effects, and the three synergistically improve the antibacterial properties;

[0129] In Comparative Example 4, the surface of the fabric was not covered with gel capsules, resulting in reduced antibacterial performance; in Comparative Example 5, peppermint oil was not added, resulting in reduced antibacterial performance; in Comparative Example 6, berry tea extract was not added, resulting in reduced antibacterial performance; this is because peppermint oil and berry tea extract contain a large amount of antibacterial volatile substances, which can improve the antibacterial performance of the fabric.

[0130] Test Example 2

[0131] The quick-drying performance of Examples 1-3 and Comparative Examples 4, 7 and 8 was tested, and the test results are shown in Table 2 below.

[0132] Table 2

[0133] Water evaporation rate (g / h) Example 1 0.385 Example 2 0.391 Example 3 0.384 Comparative Example 4 0.379 Comparative Example 7 0.242 Comparative Example 8 0.313

[0134] As can be seen from Table 2, the present application improves the hydrophilicity of the fabric by coating a hydrophilic cationic polyester polyether block copolymer on one side of the fabric, so that the fabric forms a one-sided water guide channel, improves the quick-drying effect, and avoids moisture accumulation that causes the fabric to stick to the skin and create a sticky, stuffy and uncomfortable feeling.

[0135] Test Example 3

[0136] Examples 1-3 and Comparative Example 4 were tested for washability, and the test results are shown in Table 3 below.

[0137] Table 3

[0138] Water evaporation rate (g / h) Example 1 0.367 Example 2 0.372 Example 3 0.369 Comparative Example 4 0.337

[0139] It can be seen from Table 3 that the fabrics prepared in Examples 1-3 of the present application have excellent wash resistance compared to the comparative example 4 without the addition of gel capsules. This is because the gel capsules of the present application act as connecting adhesives to enhance the adhesion of the hydrophilic cationic polyester polyether block copolymer on the surface of the fabric, thereby improving the wash resistance of the fabric and maintaining the durability of the quick-drying performance.
