Technical field

The present invention relates to hair tencel fabric production technical fields, and in particular to the burn-out printing work of a kind of mao of Tencel fabric Skill.

Background technique

Burn-out printing refers to using terylene as zinc, carries out cladding or blended formation fabric to it with fibers such as cotton, fiber crops, according to Fiber to the difference of sour part stability, in above-mentioned fabrics its acid nonfast fiber of wintercherry corrosion charing (i.e. cotton, acetic acid, viscose glue, The fibers such as fiber crops) retain its acidproof fiber terylene, the technique of translucent decorative pattern is formed on cloth cover.

Common etching slurry is divided into alkaline slurry and two kinds of alkaline slurry, wherein acting on fiber and destroying fibre structure Basic composition is corresponding sodium hydroxide and sodium hydroxide.A kind of efficient alkaline terylene etching is disclosed in CN109487592A Agent, including it is 20-30 parts of sodium hydroxide, thickener 2-20 parts alkaline-resisting, 2-10 parts of alkali-resistant penetrant, defoaming agent 0.5-5 parts alkaline-resisting, and Water surplus complements to 100 parts.When wherein alkaline slurry acts on wool fabric, sodium hydroxide is easy to cause the remaining sheep in etching part Xanthochromia occurs for wool fibre, especially after baking, so that there are color difference for etching part and non-etching part.

Therefore, it is necessary to be optimized to the burn-out printing technique of hair Tencel fabric in the prior art.

Summary of the invention

It is an object of the invention to overcome defect existing in the prior art, the burn-out printing of a kind of mao of Tencel fabric is provided Technique, etching part and the xanthochromia color difference of non-etching part are small.

To achieve the above object, the technical solution of the present invention is as follows: the burn-out printing technique of a kind of mao of Tencel fabric, feature It is, comprising the following steps:

S1: configuring alkaline etching slurry, the main component of the alkalinity etching slurry include thickener, sodium hydroxide, bleeding agent, Hydrogen peroxide, stabilizer of hydrogen peroxide, water；

S2: being applied to a mao Tencel fabric surface according to predetermined pattern for alkaline etching slurry obtained by S1, dry, be placed in 100 DEG C with It is baked under conditions of upper, rubbing is carried out to cooling fabric and is beaten, finally washing removes charred portion, and drying obtains etching print Flower hair Tencel fabric.

Preferred technical solution is, the thickener be selected from agent for polyacrylic acid thickening, converted starch, sodium alginate, The combination of one or more of natural plant gum, synthetic gum tragacanth, emulsion thickening.

Preferred technical solution is that the parts by weight of main component are respectively as follows: 3~8 parts of thickener, hydrogen in etching slurry 4~5 parts of sodium oxide molybdena, 0.5~5 part of bleeding agent, 1.5~3 parts of hydrogen peroxide, 0.2~1 part of stabilizer of hydrogen peroxide, water 75~90 Part.

Preferred technical solution is that the thickener is by converted starch and guar gum with weight ratio (2~5): 1 combination and At.

Preferred technical solution is that baking temperature is 110~120 DEG C in S2, and baking the time is 20~35min.

Preferred technical solution is that the alkalinity etching slurry further includes wool protective agent THW.

Preferred technical solution is that the parts by weight of wool protective agent THW are 0.1~0.5 part.

Preferred technical solution is that drying temperature is 60~70 DEG C in S2.

The advantages and beneficial effects of the present invention are:

The alkaline etching slurry containing hydrogen peroxide is used in the burn-out printing technique of this mao of Tencel fabric, tencel exists during etching Alkaline degradation occurs under the long duration of action of alkali, fibre structure is caused to be destroyed, hydrogen peroxide acts on wool fiber, reduces etching The xanthochromia degree of some residual fiber reduces etching part and the color difference for etching part.

Specific embodiment

With reference to embodiment, the specific embodiment of the present invention is further described.Following embodiment is only used for more Add and clearly demonstrate technical solution of the present invention, and not intended to limit the protection scope of the present invention.
