Abstract

[Problem] To provide a pure cotton fabric made of water-absorbing and quick-drying cotton yarn. [Solution] The pure cotton fabric is made by feeding water-absorbing and quick-drying cotton yarn 1 in the weft direction, bending each one to form a series of loops, and intertwining the newly generated loops with previously formed old loops. The water-absorbing and quick-drying cotton yarn includes modified cotton fibers and unmodified cotton fibers, where the mass of the modified cotton fibers accounts for 30% to 80% of the total mass of the water-absorbing and quick-drying cotton yarn. The pure cotton fabric of the water-absorbing and quick-drying cotton yarn of this invention is manufactured from water-absorbing and quick-drying cotton yarn that is interwoven with each other. The water-absorbing and quick-drying cotton yarn includes modified cotton fibers and unmodified cotton fibers. In a single cotton yarn, not only is the inherent hydrophilicity of the cotton fibers maintained, but a mixture of some modified cotton fibers is also present. This ensures that the yarn has a certain level of hydrophilicity and water-conducting performance, and the overall water retention and water absorption rate of the yarn can be reduced, thereby improving the quick-drying performance of the pure cotton yarn, and thus the quick-drying cotton fabric can be given superior quick-drying performance.

Claims (5)

The water-absorbing, quick-drying cotton yarn is fed in the weft direction, bent one by one to form a series of loops, and the newly generated loops are intertwined with the previously formed old loops, and the water-absorbing, quick-drying cotton yarn includes modified cotton fibers and unmodified cotton fibers, where the mass of the modified cotton fibers accounts for 30% to 80% of the total mass of the water-absorbing, quick-drying cotton yarn. A pure cotton fabric made from water-absorbing, quick-drying cotton yarn.
When the water-absorbing, quick-drying cotton yarn is a single yarn, the water-absorbing, quick-drying cotton yarn also includes blended yarns, and the modified cotton fibers and unmodified cotton fibers are uniformly arranged in the blended yarn, thereby ensuring that a large number of water-absorbing points exist in the water-absorbing, quick-drying cotton yarn, as well as the presence of modified fibers, and thereby reducing the overall water retention rate of the water-absorbing, quick-drying cotton yarn. A pure cotton fabric made of water-absorbing, quick-drying cotton yarn as described in feature 1.
The modified cotton fibers and the unmodified cotton fibers are uniformly arranged on the surface of the blended yarn or inside the blended yarn. The pure cotton fabric of the water-absorbing and quick-drying cotton yarn as described in feature 2.

Description

This invention relates to the field of fabric technology, and more specifically, to a pure cotton fabric made from water-absorbing and quick-drying cotton yarn. Pure cotton fabric is widely used in clothing and household textiles due to its excellent feel, breathability, and moisture absorption. However, conventional pure cotton fabrics absorb and accumulate a large amount of moisture within the fibers after sweating or contact with water, resulting in a high water retention rate and slow drying speed. This can cause a feeling of coldness and discomfort when worn, and is particularly unsuitable for situations requiring rapid moisture wicking, such as sportswear, underwear, and towels. Existing technologies typically employ the following methods to improve the quick-drying properties of fabrics: The first method involves blending hydrophobic synthetic fibers such as polyester and nylon with cotton, utilizing the low water absorption of the synthetic fibers to accelerate moisture evaporation. The second method involves applying a hydrophilic quick-drying post-processing treatment to the cotton fibers or fabric, such as coating or padding with a functional additive to give the surface a moisture-inducing and quick-drying effect. However, the first method reduces the fabric's natural feel and moisture absorption, and the addition of synthetic fibers may affect the fabric's biodegradability and environmental compatibility. The second method suffers from insufficient durability; after multiple washes, the processing effect diminishes, eventually disappearing, and the quick-drying function cannot be maintained for an extended period. Therefore, how to impart sustainable and effective water absorption and quick-drying properties to pure cotton fabric without relying on synthetic fibers and without compromising the natural properties of cotton fibers is an urgent technological challenge that needs to be addressed in this field. This is a schematic diagram of the pure cotton fabric made of water-absorbing and quick-drying cotton yarn according to the present invention.This is a schematic diagram of the water-absorbing, quick-drying cotton yarn of Example 1 of the pure cotton fabric of the water-absorbing, quick-drying cotton yarn according to the present invention.This is a schematic diagram of the water-absorbing, quick-drying cotton yarn of Example 2 of the pure cotton fabric of the water-absorbing, quick-drying cotton yarn according to the present invention.This is a scanning electron microscope image of unmodified cotton fibers of a pure cotton fabric made from water-absorbing, quick-drying cotton yarn according to the present invention, magnified 400 times.This is a scanning electron microscope image of the modified cotton fibers of the pure cotton fabric made from water-absorbing and quick-drying cotton yarn according to the present invention, magnified 400 times.This is the reaction equation for the modification of a pure cotton fabric using water-absorbing, quick-drying cotton yarn according to the present invention, using a polyvalent carboxylic acid. The following section will provide a more detailed description of the pure cotton fabric made from water-absorbing and quick-drying cotton yarn according to this invention, with reference to the drawings. Referring to Figures 1 to 6, the pure cotton fabric is made of water-absorbing, quick-drying cotton yarn, and the pure cotton fabric is made by feeding the water-absorbing, quick-drying cotton yarn 1 in the weft direction, bending each one to form a series of loops, and intertwining the newly generated loops with the previously formed old loops, and the water-absorbing, quick-drying cotton yarn 1 includes modified cotton fibers 3 and unmodified cotton fibers 2, where the mass of the modified cotton fibers accounts for 30% to 80% of the total mass of the water-absorbing, quick-drying cotton yarn 1, and the diameters of the modified cotton fibers 3 and the unmodified cotton fibers 2 are the same. (Example 1) When the water-absorbing, quick-drying cotton yarn 1 is a single yarn, the water-absorbing, quick-drying cotton yarn 1 also includes blended yarns. The uniform distribution of the modified cotton fibers 3 and unmodified cotton fibers 2 within the blended yarn ensures that the water-absorbing, quick-drying cotton yarn 1 has a large number of water-absorbing points and also contains modified fibers, thereby reducing the overall water retention rate of the water-absorbing, quick-drying cotton yarn 1. The modified cotton fibers 3 and the unmodified cotton fibers 2 are uniformly arranged on the surface of the blended yarn or within the blended yarn. This method, by uniformly mixing and spinning the modified fibers into single yarn, allows for a uniform distribution of the modified fibers, thereby controlling the overall performance of the yarn. This structure provides high flexibility in product development, allowing for optimization of the performance ratio acco
