Abstract
The application relates to the technical field of spinning, and particularly discloses a preparation process of an ultra-soft all-cotton woven fabric and the fabric thereof, wherein the preparation process of the ultra-soft all-cotton woven fabric comprises the following steps: performing shuttle weaving on the cotton fibers to obtain an ultra-soft all-cotton shuttle woven fabric; pre-impregnating the super-soft all-cotton woven fabric with a pretreatment agent for 40-60min, and then drying, wherein the liquid content after drying is controlled to be 20-30%, so as to obtain the pre-treated super-soft all-cotton woven fabric; dipping the pretreated super-soft all-cotton woven fabric in an antibacterial finishing liquid, and performing needling operation while dipping to obtain the dipped super-soft all-cotton woven fabric; carrying out rolling drying, baking and press polishing treatment on the impregnated ultra-soft all-cotton woven fabric to obtain the ultra-soft all-cotton woven fabric; the pretreatment agent consists of dodecyl dimethyl betaine, sodium hexametaphosphate and pretreatment water, and the weight ratio is 1; the super-soft all-cotton woven fabric prepared by the preparation process of the super-soft all-cotton woven fabric has the advantage of good antibacterial property.
Description
Technical Field
The application relates to the technical field of spinning, in particular to a preparation process of an ultra-soft all-cotton woven fabric and the fabric.
Background
The woven fabric is formed by interlacing warp and weft yarns in a picking mode of a weaving machine. The fabric is firm, stiff and smooth and difficult to deform due to the fact that the warp and weft of the weaving method are staggered, and the woven fabric is in the world leading position in terms of variety and production quantity in clothes.
The tatting fabric is classified from components including cotton fabrics, silk fabrics, wool fabrics, blended fabrics and interwoven fabrics of the cotton fabrics, the silk fabrics and the wool fabrics, wherein the all-cotton tatting fabric is more and more popular due to better softness, heat preservation and air permeability; the all-cotton woven fabric also has good moisture absorption performance, and under normal conditions, the fibers can absorb moisture into the surrounding atmosphere, and the moisture content of the fibers is 8-10%, so that the fibers contact the skin of a person, and the person feels soft but not stiff.
Through the related technologies, although the all-cotton woven fabric has high water absorption, when the all-cotton woven fabric is in a wet state, if bacteria, fungi and other substances are encountered, the cotton fibers are easily decomposed, and therefore, the cloth of the clothes is mildewed and degenerated.
