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

[0044] Preparation of Bleaching Solution for Polyester Fabric

[0045] Table 1: Formulation of bleaching solution for polyester fabric Unit: kg

[0046]

[0047]

[0048] According to the corresponding data in Table 1, each raw material was weighed. Potassium borate, diethylenetriaminepentamethylenephosphonic acid heptasodium salt, acrylic acid-maleic acid copolymer, 1,5-anhydroglucitol, 4-(2-nonanoyloxyethoxy Dissolve sodium benzenesulfonate and tetraacetylethylenediamine in water, add sodium hydroxide and hydrogen peroxide, and mix evenly to obtain the bleaching solution for polyester fabrics.

Embodiment 2

[0056] Bleaching method of polyester fabric

[0057] At room temperature, the polyester fabric prepared in Example 1 was dipped with bleaching solution to pad the polyester fabric, and the liquid was squeezed to 100% with a liquid manipulator, then steamed at 100°C for 50 minutes, finally washed with water at room temperature for 30 minutes, and dried.

Abstract

The invention discloses bleaching liquid for dacron fabric and a bleaching method of the dacron fabric. The bleaching liquid for the dacron fabric is composed of the following components by mass: 0.2-0.6 part of potassium borate, 0.5-1.5 parts of diethylene triamine penta (Methylene Phosphonic Acid) pentasodium salt, 0.5-1.5 parts of crylic acid maleic acid copolymer, 0.5-1.5 parts of 1,5-Anhydro-D-glucitol, 1-3 parts of 4-(2-nonanoyl acyloxy ethoxylated carbonyl tempol) benzene sulfonic acid sodium salt, 0.2-0.6 part of tetra acetyl ethylene diamine, 1.5-7.5 parts of sodium hydroxide, 2-8 parts of hydrogen peroxide and 1000 parts of water. When the bleaching liquid is used for bleaching the dacron fabric, the bleaching process is simple, the bleaching liquid is suitable for mass production, damage to the fabric is small, a bleaching effect is good, and breakage of the fabric can be effectively restrained.

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 polyester fabrics and a bleaching method for polyester 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 removed by the effect of bleach...
