Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of textiles, and particularly relates to a hard and smooth double-sided knitted fabric and application of a preparation method thereof. BACKGROUND

[0002] With the continuous improvement of the quality of life, people's demand for the comfort and functionality of wearing textiles and garments is increasing, especially the comfort and skin-friendly texture of sports clothing fabrics are more concerned by people. The skin-friendly texture mainly refers to the fabric contacting the human skin has softness, silkiness and elasticity; and the comfort mainly refers to the fabric can take away the sweat and body odor on the body, avoid the discomfort caused by the clothes sticking to the body after sweating, so the fabric is required to quickly transport water vapor and sweat to the surface of the fabric, and then evaporate and diffuse to the outside environment, so as to ensure the hygiene and comfort of the fabric.

[0003] At present, although cotton fabrics have the characteristics of softness, they mainly achieve soft hand feeling by adding a large amount of chemical auxiliaries in the dyeing and finishing process, but in the daily use process, a large amount of chemical auxiliaries is lost after washing, and the fabric hand feeling becomes stiff; and the use of a large amount of chemical auxiliaries further damages the increasingly fragile ecological environment, which is contrary to the current advocated green and low-carbon production and lifestyle. In addition, in the process of pursuing high quality, especially smoothness, the demand for long-staple cotton increases, which increases the cost of the fabric.

[0004] CN113832723A discloses a cotton fiber fabric and a manufacturing method thereof. The manufacturing method of the cotton fiber fabric comprises the following steps: (1) preparing a treatment liquid and a softening liquid: adding a modifier, a penetrant and a catalyst into water to prepare the treatment liquid, wherein the modifier comprises water-based polyurethane and chitosan, and adding a softening agent into water to prepare the softening liquid; (2) impregnating the cotton fiber: impregnating the cotton fiber in the treatment liquid, and then impregnating in the softening liquid after pre-drying; (3) baking: baking the cotton fiber obtained in step (2); (4) washing; (5) drying; (6) weaving the cotton fiber obtained in step (5) into a cotton fiber fabric; the cotton fiber fabric obtained by the present application has no formaldehyde residue, soft texture, comfortable use, and the wrinkle resistance is improved while the mechanical properties are maintained. However, the fabric provided by the above-mentioned application cannot be well compatible with the silkiness finishing after the hardening finishing, that is, it cannot have both the effects of hardening and silkiness.
