Embodiment 1

[0017] 1) Due to the presence of a large amount of oil, cotton shells and impurities on the cotton knitted fabric gray cloth, conventional pre-treatment scouring and bleaching processes must be used to fully remove impurities, maintain good wettability and permeability of the fabric, and have a good capillary effect. In order to enhance and improve the adsorption effect of the paint on the fabric and the smoothness of the cloth surface, the pre-treated knitted fabric is desinged and mercerized.

[0018] 2) In the mixed dye solution bath with paint and water-soluble butyl acrylate and acrylamide copolymer modified by epoxy resin as adhesive, adjust the adhesive concentration to 20g / L, and apply paint to the fabric For dyeing treatment, the dyeing temperature is controlled at 70°C, the pH is 7.0, the dyeing time is 2h, and the liquor ratio is 1:25; it is dried at 100°C, and then baked at 150°C for 3 minutes.

[0019] 3) After printing, heat setting is carried out by a setting ma...

Abstract

An all cotton fabric dyeing process with high fixation performance mainly includes the following steps of pretreating, singeing and mercerizing, pigment dyeing, pigment printing, shaping and preshrinking, washing and drying, wherein an adhesive used for pigment used in pigment dyeing and pigment printing is water soluble butyl acrylate and acrylamide copolymer modified by epoxy resin, and the concentration of the copolymer is 20-30 g / L. The dyeing temperature of the pigment is controlled to be 60-70 DEG C, the pH value is 7.0-8.0, the time is 1-2 h, and the bath ratio is 1:25; all cotton fabric is dried after dyeing and then baked for 3-5 min at the temperature of 150 DEG C. The water soluble butyl acrylate and acrylamide copolymer modified by epoxy resin is used as the pigment adhesive, color fastness of the fabric is improved, water consumption is reduced by means of the washing process with cold water and hot water alternating, and sewage discharge amount is reduced.

Description

technical field [0001] The invention relates to a fabric and its processing technology, in particular to a fabric paint dyeing process, which belongs to the technical field of textile printing and dyeing. Background technique [0002] In terms of fabric dyeing, the traditional process is to choose such as acid dyes, reactive dyes, vat dyes and disperse dyes for dyeing according to the nature, color and quality requirements of the fibers. Due to the complicated production process when using traditional dyes, it is difficult to control the dyeing quality, and the dyes, sodium hydrosulfite, sodium vanadium and sodium nitrite used are all toxic substances, which are not good for producers and the environment. The paint dyeing process is completely different from the traditional dyeing process. It is a dyeing method that uses adhesives to fix pigments (which have no affinity and reactivity to the fabric) on the surface of the fabric. [0003] Pigment dyeing has universal applica...
