Abstract
The invention relates to the technical field of textiles, in particular to a finishing method for improving the non-ironing property and hand feeling of pure cotton plain yarn-dyed fabric. Comprises the steps of singeing, desizing, primary loose type drying, mercerizing finishing, secondary loose type drying, liquid ammonia finishing, tertiary loose type drying, non-ironing finishing, baking, tentering and preshrinking; mercerizing finishing and liquid ammonia finishing are respectively processed by a loose mercerizing machine and a loose liquid ammonia machine, wet cropping is adopted for processing, and non-ironing finishing is carried out by using a non-ironing auxiliary agent. The pure cotton plain yarn-dyed fabric is subjected to mercerizing finishing and liquid ammonia finishing by using the loose mercerizing machine and the loose liquid ammonia machine, and then is treated by using the non-ironing auxiliary agent, so that the non-ironing performance and hand feeling of the fabric are improved, the fabric is soft and elastic in hand feeling, and the non-ironing performance of the fabric is 4.3-4.5 grades after 10 times of washing.
Description
Technical Field
The invention relates to the technical field of textiles, in particular to a finishing method for improving the non-ironing property and hand feeling of pure cotton plain yarn-dyed fabric.
Background
The pure cotton fabric takes cotton as a raw material, has a thick production area, and is one of the most common raw materials contacted by people in daily life; the fabric has good moisture absorption and heat resistance, no peculiar smell and no irritation, is comfortable and textured to wear, and is always the material sought by consumers. The plain weave fabric is light and thin, has good air permeability and no stuffy feeling, and is always the preferred material of the formal dress fabric; however, the plain weave fabric has a tight fabric weave structure and a plurality of interweaving points, so that the fabric has hard hand feeling, small elasticity and poor crease resistance; the plain weave fabric has the most difficult ironing-free effect in three weaves of plain weave, twill weave and satin weave. In pure cotton plain non-ironing fabrics on the market at the present stage, the non-ironing property of deep color fabrics is the highest, the grade of the deep color fabrics can reach 3.5 grade, and the non-ironing property of common light color fabrics can only reach the level of 3.2-3.5 grade.
The prior pretreatment process flow of the dyed fabric is generally singeing-desizing-mercerizing or singeing-desizing-mercerizing-liquid ammonia, which are all compact equipment, the fabric is dried by a drying cylinder, the tension of the equipment reaches 250-300N, and the fabric is rapidly cooled after being dried by the drying cylinder at high temperature because of the large tension of the equipment, so that the fabric becomes stiff and inelastic, and the liquid carrying amount and the hand feeling during the post-processing of the fabric are influenced. And the existing non-ironing technology generally has the characteristics that the smoothness of the fabric is improved along with the increase of the resin consumption, but the hand feeling of the fabric is astringent and hard.
Chinese patent CN105714559A discloses a non-ironing finishing method for pure cotton piece-dyed fabric.
