A method for improving the air permeability of paint-dyed fabric

Abstract

The invention relates to a method for improving air permeability of a pigment dyed fabric, in particular to a method for performing physical pretreatment on a fabric which is soaked by padding liquor and not pre-dried so as to improve air permeability of the fabric, and belongs to the field of textile processing. In the whole process of pigment dyeing of a fabric C, a negative pressure induced draft device is arranged between the padding liquor soaking and the pre-drying process of the fabric C, pigment in fabric slits is removed in a negative pressure suction mode, the treated fabric C is pre-dried, the pre-drying temperature is 80-100 DEG C, and the pre-drying time is 5-10 min. The pigment dye liquor which affects the air permeability of the fabric C can be sucked out of the pigment dyed fabric C treated through the method, and the air permeability of the fabric C is obviously improved.

Description

technical field

[0001] The invention relates to a method for improving the air permeability of paint dyed fabrics, in particular to a method for improving the air permeability of fabrics by physically pretreating fabrics 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. The pores in the fabric include straight-through pores and amorphous po...
