Problems solved by technology

Sodium chlorite is also a good bleaching agent for chemical fibers. The whiteness stability of bleached fabrics is better than that of chlorine bleached and oxygen bleached fabrics. However, sodium chlorite is more expensive and highly corrosive to metals. Titanium or titanium is required. Alloy and other materials, and toxic ClO is produced during sub-bleaching 2 Gas, the equipment needs to be well sealed, so it is limited in use

Embodiment 1

[0037] Preparation of Bleaching Solution for Acrylic Cotton Blended Fabric

[0038] Table 1: Formulation table of bleaching solution for acrylic cotton blended fabric Unit: kg

[0039]

[0040]

[0041] According to the corresponding data in Table 1, each raw material was weighed. At room temperature, potassium borate, hexapotassium hexamethylenediamine tetramethylene phosphonate, acrylic acid maleic acid copolymer, 1,5-anhydroglucitol, 4-(2-nonanoyloxyethoxycarbonyloxy Base) sodium benzenesulfonate and tetraacetylethylenediamine are dissolved in water, then add sodium hydroxide and hydrogen peroxide, and mix evenly to obtain the bleaching solution for the acrylic cotton blended fabric.

Embodiment 2

[0049] Bleaching method of acrylic cotton blended fabric

[0050] At room temperature, the acrylic-cotton blended fabric obtained in Example 1 is dipped into the acrylic-cotton blended fabric with a bleach solution, and the liquid is squeezed to a 100% excess rate with a manipulator, then steamed at 100° C. for 50 min, and finally washed with water at normal temperature for 30 minutes. ,dry.

Abstract

The invention discloses a bleaching liquid and a bleaching method for an acrylic cotton blended fabric. The bleaching liquid comprises the following components in parts by weight: 0.2 to 0.6 part of ammonium borate, 0.5 to 1.5 parts of ethylenediamine tetramethylene phosphonate six-potassium salt, 0.5 to 1.5 parts of acrylic acid maleic acid copolymer, 0.5 to 1.5 parts of 1, 5-anhydrous glucitol, 1 to 3 parts of 4-(2-nonanoyl acyloxy ethyoxyl carbonyl oxygroup) sodium benzene sulfonate, 0.2 to 0.6 part of tetra acetyl ethylene diamine, 1.5 to 7.5 parts of sodium hydroxide, 2 to 8 parts of hydrogen peroxide and 1000 parts of water. When the bleaching liquid is used for bleaching the acrylic cotton blended fabric, the bleaching process is simple, so that the bleaching liquid is suitable for mass production. The bleaching liquid is less in fabric strength damage and good in bleaching effect, and can be used for effectively preventing the fabric from being broken.

Description

technical field [0001] The invention relates to a bleaching solution for fabrics and a fabric bleaching method, in particular to a bleaching solution for acrylic-cotton blended fabrics and a bleaching method for acrylic-cotton blended fabrics. Background technique [0002] In the textile dyeing and finishing process, after the fabric is scoured, most of the natural and artificial impurities on the fabric have been removed, and the capillary effect has been significantly improved, which can meet the processing requirements of some varieties. However, for bleached fabrics and brightly colored light-colored and colored fabrics, the whiteness needs to be improved, so it is necessary to further remove the pigment on the fabric to make the fabric whiter. Furthermore, although the fabric has been scoured, especially the normal-pressure steam scoured, there are still some impurities such as cotton seed hulls that cannot be completely removed. These impurities can be completely remov...
