Embodiment 1

[0023] Table 1: Formula table of desizing solution (aqueous solution) for polyester 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 tripolyphosphate, hydrogen peroxide, 4-(2-nonanoyloxyethoxycarbonyloxy) sodium benzenesulfonate and N-carboxymethyl-N-methylglycinate iron (III) sodium salt are added to the water, Then add sodium hydroxide, adjust the pH value to 12, and stir evenly to obtain the desizing liquid for polyester fabric.

[0026] Immerse the polyester 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 for 40 minutes ,dry.

Abstract

The invention discloses a desizing liquid and a desizing method for dacron fabric. The desizing liquid has the pH value between 11 and 12 and comprises the following components: 1 to 3g / L of sodium tripolyphosphate, 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 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 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 polyester fabrics and a desizing method for polyester 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 yarn co...
