Embodiment 1

[0032] Fabric specification: 105” / 40s*40s / 144*76, cotton satin

[0033] The fabric goes through the following conventional processes: singeing (two fronts and two reverses) → desizing → scouring → bleaching → tentering → mercerizing → whitening → printing → steaming → washing → waterproof and oil-proof finishing → calendering → preshrinking → finished product. After the fabric is processed through the above process, it can obtain better waterproof and oil-proof effect.

[0034] Among them, in the printing process, the printing paste prescription:

[0035] 0.1 part of magnesium chloride; 0.5 part of fatty alcohol polyoxyethylene ether sulfonate (3EO); 8 parts of reactive red 3BS; 2.5 parts of sodium alginate; 1.5 parts of sodium bicarbonate; 6 parts of urea; water; 100 parts total.

[0036] After the fabric is printed, the fabric is steamed and washed, and the washed fabric is waterproof and oil-proof. The waterproof and oil-proof finishing process and working fluid prescript...

Embodiment 2

[0040] Fabric specification: 105” / 40s*40s / 133*72, cotton twill

[0041] The fabric goes through the following conventional processes: singeing (two fronts and two reverses) → desizing → scouring → bleaching → tentering → mercerizing → whitening → printing → steaming → washing → waterproof and oil-proof finishing → calendering → preshrinking → finished product. After the fabric is processed through the above process, it can obtain better waterproof and oil-proof effect.

[0042] Among them, in the printing process, the printing paste prescription:

[0043] 0.05 parts of calcium chloride; 0.1 parts of magnesium chloride; 0.8 parts of fatty alcohol polyoxyethylene ether sulfonate (3EO); 12 parts of reactive red 3BS, 3 parts of sodium alginate; 2 parts of sodium bicarbonate; parts; the balance is water; a total of 100 parts.

[0044] After the fabric is printed, the fabric is steamed and washed, and the washed fabric is waterproof and oil-proof. The waterproof and oil-proof fini...

Embodiment 3

[0048] Fabric specification: 105” / 60s*60s / 200*100, cotton satin

[0049] The fabric goes through the following conventional processes: singeing (two fronts and two reverses) → desizing → scouring → bleaching → tentering → mercerizing → whitening → printing → steaming → washing → waterproof and oil-proof finishing → calendering → preshrinking → finished product. After the fabric is processed through the above process, it can obtain better waterproof and oil-proof effect.

[0050] Among them, in the printing process, the printing paste prescription:

[0051] 0.02 parts of calcium chloride, 0.04 parts of zinc chloride; 0.3 parts of fatty alcohol polyoxyethylene ether sulfonate (3EO); 5 parts of reactive red 3BS; 2 parts of sodium alginate; 1 part of sodium bicarbonate; 5 parts of urea; anti-reduction 0.5 part of agent; the balance is water; a total of 100 parts.

Abstract

The invention provides a processing method for enhancing water resistance and oil resistance of a cellulosic fiber fabric. The processing method comprises a printing process and a water resistance and oil resistance finishing process, wherein in the printing process, printing paste contains organic matters with positive charges or inorganic metallic salt with negative charges; a 6-fluorocarbon additive or a 4-fluorocarbon additive is adopted for water resistance and oil resistance finishing. According to the processing method provided by the invention, the processed fabric is bright in color and comparatively good in color yield, and the same fabric has comparatively good effects of water resistance and oil resistance no matter the color of a flower type is dark or shallow; the fabric still has comparatively good and lasting water resistance and oil resistance even if the fabric is washed repeatedly.

Description

technical field [0001] The invention belongs to the technical field of dyeing and finishing of cellulose fiber fabrics, and in particular relates to a processing method for improving the waterproof and oil-proof performance of cellulose fiber fabrics. Background technique [0002] The waterproof and oil-proof finishing of textiles is a common and important functional finishing, which can mainly include two effects: one is that water stains or oil stains have less staining on fabrics; the other is that stains are easily stained on fabrics Removes, not as difficult to remove as absorbent stains. [0003] In the field of waterproof and oil-repellent agents, fluorine-based waterproof agents are the most widely used, while traditional fluorine-containing waterproof agents are mostly eight-carbon structures, which have good chemical stability and hydrophobic and oleophobic properties. comparative superiority. However, octacarbon fluorine-based waterproofing agents contain compou...
