Problems solved by technology

Therefore, based on the above two reasons, the softness of the fabric after dyeing with paint decreases
[0003] Chinese patent application publication number CN102041698A, the application publication date is May 4, 2011, the name of the invention is "a preparation method of luminous printed fabric", the application discloses a method to solve the fabric softness, using a tenter The mechanical external force will destroy the paint film that blocks the pores, which is beneficial to the mutual displacement of the yarns and the enhancement of the air permeability of the fabric. It will cause the film in some pores to fall off easily, which will affect the wearing performance of the fabric

Abstract

The invention relates to a method for improving softness performance of pigment dyed fabric, particularly relates to a method for performing physical pre-processing after the fabric is soaked with padding liquor and before the fabric is pre-dried so as to improve the softness performance of the fabric, and belongs to the field of textile processing. In the whole pigment dyeing process of fabric D, a negative-pressure air suction device is arranged between the padding liquor soaking procedure and the pre-drying procedure of the fabric D, pigment in gap holes of the fabric is removed in a negative pressure suction mode, the processed fabric D is pre-dried, pre-drying temperature is 80-100 DEG C, and pre-drying time is 5-10 min. The pigment dyed fabric D processed through the technological method can suck out pigment dye liquor affecting the softness performance of the fabric D, adhesion between yarn is reduced, and the softness degree of the fabric D is improved obviously.

Description

technical field [0001] The invention relates to a method for improving the softness of paint-dyed fabrics, in particular to a method for improving the softness of fabrics by physical pretreatment after padding with paint dye solution before pre-drying, and belongs to the field of textile processing. Background technique [0002] In paint dyeing, paint includes pigments and binders. Pigments include organic pigments and inorganic pigments. Both pigments are micron-sized particles and have no affinity for all coloring objects. Binders are viscous substances. Properties To connect two separate materials together, pigments must rely on adhesives to attach to the fiber surface. After the adhesive is dried, the macromolecules are cross-linked into a network structure, and the pigment is distributed in the adhesive in a molecular state, forming a tough film-like material on the fabric. After the fabric paint is dyed, the paint will remain in the pores of the fabric, especially bet...
