Embodiment 1

[0024] Table 1: Formulation of desizing solution (aqueous solution) for cotton-polyester blended fabrics

[0025]

[0026] 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 citrate, hydrogen peroxide, 4-(2-nonanoyloxyethoxycarbonyloxy) sodium benzenesulfonate and N-carboxymethyl-N-methylglycinate iron (III) sodium salt are added to water, and then Add sodium hydroxide, adjust the pH value to 12, and stir evenly to obtain the desizing liquid for the cotton-polyester blended fabric.

[0027] At room temperature, soak the cotton-polyester blended fabric in the desizing solution prepared above, with a bath ratio of 1:20, raise the temperature to 70°C, and soak for 60min while keeping the temperature at 70°C; steam at 100°C for 50min, and then Wash with water for 40min and dry.

Abstract

The invention discloses a desizing liquid and a desizing method for a dacron cotton blended fabric. The desizing liquid has the pH value between 11 and 12 and comprises the following components: 1 to 3g / L of sodium citrate, 4 to 8g / L of hydrogen peroxide, 2 to 4mumol / L of binuclear manganese complexes, 1 to 3g / L of 4-(2-nonanoyl acyloxy ethyoxyl carbonyl oxygroup) sodium benzene sulfonate, 0.5 to 1.5g / L of N-carboxymethyl-N-methyl ferric glycine (III) sodium salt and proper amount of sodium hydroxide. When the desizing liquid is utilized for performing desizing treatment on the dacron cotton blended fabric, the desizing rate is high as well as the obtained fabric is high in capillary effect and mechanical property, so that the implementation of the subsequent dyeing and printing process is facilitated and the subsequent dyeing and the printing quality is guaranteed. In addition, the sizing slurry is removed effectively, so that the fabric handfeeling is improved.

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 cotton-polyester blended fabrics and a desizing method for cotton-polyester blended 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....
