Problems solved by technology

Among them, when the alkaline slurry acts on the wool fabric, sodium hydroxide is likely to cause yellowing of the wool fiber remaining in the burnt-out part, especially after baking, resulting in a color difference between the burnt-out part and the non-burnt-out part

Embodiment 1

[0020] The burnt-out printing process of embodiment 1 wool tencel fabric comprises the following steps:

[0021] S1: Configure alkaline burnt-out slurry, the main components of the alkaline burnt-out slurry include thickener, sodium hydroxide, penetrant, hydrogen peroxide, hydrogen peroxide stabilizer, and water;

[0022] S2: Apply the alkaline burnt-out slurry obtained in S1 to the surface of the tencel fabric according to the predetermined pattern, dry it, bake it at a temperature above 100°C, rub and beat the cooled fabric, finally wash it with water to remove the carbonized part, and dry it , get burnt-out printing wool tencel fabric.

[0023] The thickener is one or a combination of two or more selected from polyacrylic thickeners, modified starches, sodium alginate, vegetable gums, synthetic dragon gums, and emulsified pastes.

[0024] The parts by weight of the main components in the alkaline burnt-out slurry are: 3 parts of thickener, 5 parts of sodium hydroxide, 0.5 ...

Embodiment 2

[0029] Example 2 is based on Example 1, the difference is that the parts by weight of the main components in the alkaline burnt-out slurry are: 8 parts of thickener, 4 parts of sodium hydroxide, 5 parts of penetrant, and 1.5 parts of hydrogen peroxide , 1 part of hydrogen peroxide stabilizer, 75 parts of water.

[0030] The thickener is composed of modified starch and guar gum in a weight ratio of 5:1.

[0031] The baking temperature in S2 is 120°C, and the baking time is 20 minutes.

[0032] The drying temperature in S2 is 70°C.

Embodiment 3

[0034] The difference between Example 3 and Example 1 is that the parts by weight of the main components in the alkaline burnt-out slurry are: 5 parts of thickener, 4.5 parts of sodium hydroxide, 2 parts of penetrant, and 2 parts of hydrogen peroxide , 0.7 parts of hydrogen peroxide stabilizer, 85 parts of water.

[0035] The thickener is composed of modified starch and guar gum in a weight ratio of 3:1.

[0036] The baking temperature in S2 is 115°C, and the baking time is 25min; the drying temperature in S2 is 65°C.

Abstract

The invention discloses a burnt-out printing technology of wool tencel fabrics. The burnt-out printing technology includes the two steps of preparation of an alkaline burnt-out sizing agent and burnt-out processing. In the burnt-out printing technology of the wool tencel fabrics, the alkaline burnt-out sizing agent containing hydrogen peroxide is adopted, in the burnt-out process, under the actionof alkali for a long time, tencel undergoes alkali degradation, so that the fiber structure is destroyed; hydrogen peroxide acts on wool fibers to lower the yellowing degree of the remaining fibers of the burnt-out part, and thus the color difference between the burnt-out part and the non-burnt-out part is reduced.

Description

technical field [0001] The invention relates to the technical field of wool tencel fabric production, in particular to a burn-out printing process for wool tencel fabrics. Background technique [0002] Burn-out printing refers to using polyester as zinc, covering it with cotton, hemp and other fibers or blending it to form a fabric. According to the difference in the stability of the fiber to the acid, the acid pulp on the above fabric corrodes and carbonizes the non-acid-resistant fiber ( That is, cotton, acetic acid, viscose, hemp and other fibers) retain their acid-resistant fiber polyester and form a translucent pattern on the cloth surface. [0003] The commonly used burnt-out pulp is divided into two types: alkaline pulp and alkaline pulp. The basic components that act on fibers and destroy the fiber structure are corresponding sodium hydroxide and sodium hydroxide. Disclosed in CN109487592A is a high-efficiency alkaline polyester burn-out agent, including 20-30 parts...
