Embodiment 1

[0020] fabric dyeing

[0021] ①Pre-treatment of fabric dyeing; gray cloth is bleached with hydrogen peroxide bleach before dyeing, and the pH value of the bleaching solution is adjusted to 10 with NaOH, and the prescription of the bleaching solution; 100% H 2 o 2 10 g / L, hydrogen peroxide stabilizer 3 g / L, micromolecular high-efficiency scouring agent 12 g / L, scouring whitening agent 2 g / L; the above weight is based on per liter of water. The process conditions are two dipping and one rolling, bleaching solution padding, padding pressure 0.1Mpa, rolling excess rate 85%, process parameters are vehicle speed 10m / min, steaming temperature 100°C, and steaming time 25min. The pH value of the bleach solution is adjusted to 10 with NaOH, which is weakly alkaline. The high-proportion hydrogen peroxide bleaching process and the addition of micromolecular high-efficiency scouring agents are used to eliminate the influence of part of the pectin and wax of cotton fibers and the yellow ...

Embodiment 2

[0027] White ground printing of fabrics

[0028] ① Fabric printing pre-treatment; gray fabrics are bleached with hydrogen peroxide bleach before printing, the bleaching solution is adjusted to a pH value of 9.5 with NaOH, and the bleaching solution is prescribed; 100% H 2 o 2 20 grams per liter, 4 grams per liter of hydrogen peroxide stabilizer, 6 grams per liter of high-efficiency micromolecular scouring agent, and 4 grams per liter of scouring whitening agent; the above weight is based on per liter of water. The process conditions are two dipping and one rolling, bleaching solution padding, padding pressure 0.1Mpa, rolling surplus rate 85%, process parameters are vehicle speed 10m / min, temperature 100°C, time 25min.

[0029] ②Floating cloth drying, steaming, washing and drying; the steaming is a hanging long ring steaming

[0030] ③Fabric printing; printing with neutral reactive dyes, the pH value of the color paste is 7, printing prescription; CN type reactive dyes react...

Embodiment 3

[0034]color ground printing of fabric

[0035] ①Pretreatment of fabric dyeing; bleaching with hydrogen peroxide bleach before dyeing, the pH value of the bleaching solution is 10.5, the prescription of the bleaching solution; 100% H 2 o 2 15 g / L, 7 g / L hydrogen peroxide stabilizer, 6 g / L micromolecular high-efficiency scouring agent, 2 g / L scouring whitening agent; based on each liter of water, add the bleach described in the prescription in 60-70 °C water Bleaching agent and bleaching aids make up the bleaching solution. The process conditions are two dipping and one rolling, bleaching solution padding, padding pressure 0.1Mpa, rolling surplus rate 85%, process parameters are vehicle speed 10m / min, temperature 100°C, time 25min.

[0036] ②Floating cloth drying, steaming, washing, and drying; the steaming is a hanging long-loop steaming process. The selection of the long-ring steaming process can prevent the contact between the cloth surfaces from staining the puffed yello...

Abstract

The invention relates to a dyeing and finishing method of cotton / milk egg albumen blending raschel fabric, and the method comprises first, processing fabric before dyeing, second, drying, steaming, washing and drying keffekilite, third, dyeing and printing the fabric, fourth, dyeing or steaming, washing, flexibly handing, stentering or drying print cloth. The invention chooses CN-type reactive dyes and micro-molecular high-performance scouring assistants, and a set of new technological method. The invention solves technical incompatibility of two fibers which are cotton and bovine albumin. The invention has the advantages of low production cost, little pollution, bright color and even dyeing, and excellent performance of bovine albumin fiber can keep invariant.

Description

technical field [0001] The invention relates to a method in the technical field of textile printing and dyeing, in particular to a method for dyeing and finishing cotton / milk protein blended raschel fabrics. Background technique [0002] At present, 100% cotton is the absolute mainstream of domestic bedding fabrics. Cotton and its products have good moisture absorption and breathability, and are not easy to be eaten by insects. It has become the first choice for people's clothing for thousands of years. Its biggest disadvantage is that it is easy to wrinkle and has to be washed many times. The after effects are aesthetically pleasing. Wool and cashmere fabrics are soft to the touch and have good warmth retention properties, but are prone to insects and are expensive. [0003] Milk protein fiber (Milk Casein Fiber) is a graft copolymerization of milk protein and acrylonitrile macromolecules to form a linear macromolecule containing milk protein amino acid macromolecules in t...
