Embodiment 1

[0023] Table 1: Formula table of desizing solution (aqueous solution) for brocade silk fabric

[0024]

[0025] According to the corresponding data in Table 1, each raw material was weighed. The binuclear manganese complex [Mn 2 IV (μ-O) 3 (Me 3 TACN) 2 ][PF 6 ] 2 ·H 2 O, sodium gluconate, hydrogen peroxide, 4-(2-nonanoyloxyethoxycarbonyloxy) sodium benzenesulfonate and N-carboxymethyl-N-methyl glycinate iron (III) sodium salt are added in water, and then Add sodium hydroxide, adjust the pH value to 12, and stir evenly to obtain the desizing liquid for the brocade silk fabric.

[0026] Immerse the brocade silk fabric in the desizing solution prepared above at room temperature, with a bath ratio of 1:20, raise the temperature to 70°C, and keep the temperature at 70°C for 60 minutes; steam at 100°C for 50 minutes, and then wash with water 40min, dry.

Abstract

The invention discloses desizing liquid for brocade silk fabric and a desizing method of the brocade silk fabric. The pH value of the desizing liquid for the brocade silk fabric is 11-12; and the desizing liquid consists of the following components: 1-3g / L of sodium gluconate, 4-8g / L of hydrogen peroxide, 2-4mumol / L of a dinuclear manganese complex, 1-3g / L of 4-(2-nonanoyloxyethoxycarbonyloxy) sodium benzene sulfonate, 0.5-1.5g / L of N-carboxymethyl-N-iron methylglycine (III) sodium salt and a proper amount of sodium hydroxide. By adopting the desizing liquid disclosed by the invention to perform desizing treatment on the brocade silk fabric, the desizing rate is high, the obtained desized fabric has a high capillary effect and a high mechanical performance and is favorable for performing successive dyeing and finishing technologies, and the successive dyeing and finishing quality is guaranteed; and moreover, the hand feeling of the fabric is improved since size is effectively removed.

Description

technical field [0001] The invention relates to a desizing liquid for fabrics and a desizing method for fabrics, in particular to a desizing liquid for brocade silk fabrics and a desizing method for brocade silk fabrics. Background technique [0002] In the textile dyeing and finishing process, the fabric with yarn as warp must be sizing before weaving to improve the strength, wear resistance and smoothness of warp yarn, thereby reducing warp yarn breakage and ensuring smooth weaving. The sizing materials used for warp yarn sizing include natural sizing materials such as starch and wild starch, chemical sizing materials such as polyvinyl alcohol (PVA), polyacrylic acid (PAA), and cellulose preparations such as carboxymethyl cellulose (CMC). Other ingredients such as preservatives, softeners, hygroscopic agents, wear-reducing agents, etc. are also added to the sizing solution. The warp sizing rate is related to fiber quality, yarn count, density, etc. For fabrics with fine y...
