[0066] In the preparation method provided by the present invention, the grey cloth is preferably washed before being soaked in liquid ammonia to fully remove impurities on the grey cloth, such as oil, wax, cottonseed hulls, natural pigments, etc. After washing, the cloth is dried and cooled.

[0067] In the preparation method provided by the present invention, during the liquid ammonia soaking process, ammonia molecules can instantly penetrate into the interior of the fiber, so that the hydrogen bonds within and between the fiber molecular bundles are broken up; then when the ammonia molecules are removed, the fiber macromolecules are reconnected by hydrogen bonds and rearranged, so that the fiber surface changes, the internal stress of some fibers is reduced, the natural twist of the fibers is weakened, the cross-section is more elliptical, the surface contact area is increased, the mirror reflectivity of light and the toughness of the fibers are increased, and residual impurities on the fibers can be further removed, thereby improving the overall quality and appearance of the fabric. In addition, the hand feel and comfort of the fabric can be further improved after the liquid ammonia soaking.

[0068] In the preparation method provided by the present invention, during the liquid ammonia soaking process, the temperature of the liquid ammonia is preferably -33 to -35°C, specifically -33°C, -34°C or -35°C; the soaking pressure is preferably at normal pressure; the soaking time is preferably 5 to 20 seconds, specifically 5 seconds, 6 seconds, 7 seconds, 8 seconds, 9 seconds, 10 seconds, 11 seconds, 12 seconds, 13 seconds, 14 seconds, 15 seconds, 16 seconds, 17 seconds, 18 seconds, 19 seconds or 20 seconds. In the present invention, the diffusion rate of ammonia molecules during the soaking process can be controlled by adjusting the liquid ammonia soaking conditions, thereby achieving fine control of the ammonia soaking treatment effect of the fabric.

[0069] In the preparation method provided by the present invention, after the liquid ammonia soaking is completed, the deamination and deodorization of the fabric is achieved by the drying; wherein the drying method is preferably sealed drying; the drying temperature is preferably 100-150°C, specifically 100°C, 105°C, 110°C, 115°C, 120°C, 125°C, 130°C, 135°C, 140°C, 145°C or 150°C; the drying time is preferably 1-5 minutes, specifically 1 minute, 1.5 minutes, 2 minutes, 2.5 minutes, 3 minutes, 3.5 minutes, 4 minutes, 4.5 minutes or 5 minutes.

[0070] The present invention also provides a comfortable knitted fabric treated with liquid ammonia, which is prepared according to the preparation method described in the above technical solution. In the present invention, the weight of the comfortable knitted fabric is preferably 150 to 250 g / m 2 , specifically 150g / m 2, 155g / m 2 , 160g / m 2 , 165g / m 2 , 170g / m 2 , 175g / m 2 , 180g / m 2 , 185g / m 2 , 190g / m 2 , 195g / m 2 , 200g / m 2 , 205g / m 2 , 210g / m 2 , 215g / m 2 , 220g / m 2 , 225g / m 2 , 230g / m 2 , 235g / m 2 , 240g / m 2 , 245g / m 2 or 250g / m 2 .

[0071] The technical solution provided by this invention uses antibacterial Sorona and long-staple cotton as weaving materials, which conforms to the general trend of green environmental protection. The fabric produced using this technical solution not only has stable cooling and antibacterial properties, but also has higher gloss, better wear resistance, better wrinkle resistance, more stable dimensions, and better comfort. In addition, the surface of the fabric has a twill texture jacquard, which can meet the needs of more consumer groups. More specifically, the technical solution of this invention has the following key points and advantages:

[0072] (1) Selection and matching of raw materials: long-staple cotton is used as the weaving yarn for the base yarn and the veil, and Sorona yarn with jade powder and antibacterial agent added is used as the connecting yarn for the base yarn and the veil; the use of long-staple cotton can retain the touch of natural cotton fiber in the fabric; Sorona yarn is made of bio-based PDO (1,3-propylene glycol) and PTA (terephthalic acid) as the main raw materials, which is green and environmentally friendly. The unique "small spring" structure in its molecular structure can make the fabric have long-lasting and comfortable elasticity and recovery, and it is straight and not deformed; the addition of jade powder and antibacterial agent in Sorona yarn increases the cool and antibacterial properties of the fabric.

[0073] (2) Twill jacquard design: The two sides of the fabric can present different twill texture jacquards. The front side has a left-diagonal texture, while the back side has a right-diagonal texture. The textures on both sides are delicate and unique, giving customers a variety of choices for clothing.

[0074] (3) Liquid ammonia soaking treatment: During the liquid ammonia soaking process, ammonia molecules can instantly penetrate into the fiber, breaking up the hydrogen bonds within and between the fiber molecular bundles; then when the ammonia molecules are removed, the fiber macromolecules are reconnected by hydrogen bonds and rearranged, causing the fiber surface to change, reducing the internal stress of some fibers, weakening the natural twist of the fibers, and making the cross-section more elliptical, which increases the surface contact area, improves the dyeing performance, increases the mirror reflectivity of light and the toughness of the fiber, and can further remove residual impurities on the fiber, improving the overall quality and appearance of the fabric. In addition, the fabric's feel and comfort can be further improved after being soaked in liquid ammonia.

[0075] For the purpose of greater clarity, the present invention is described in detail with reference to the following examples.
