Abstract
The invention discloses a desizing liquid and a desizing method for a linen fabric. The desizing liquid has the pH value between 11 and 12 and comprises the following components: 1 to 3g/L of sodium silicate, 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 linen 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 guaranteed. In addition, the sizing slurry is removed effectively, so that the fabric handfeeling is improved.
Description
Technical field
The present invention relates to a kind of fabric with the desizing method of desizing liquid and fabric, relate in particular to a kind of sodolin with the desizing method of desizing liquid and sodolin.
Background technology
In weave dyeing and finishing technique, the fabric take yarn as warp all must be processed through starching before weaving, and with brute force, ABRASION RESISTANCE and the smooth degree of raising warp thread, thereby reduces warp end break, and guaranteeing weaves cotton cloth carries out smoothly.Warp sizing oar material used has natural slurry such as starch, wild starch, chemical sizwe such as polyvinyl alcohol (PVA), polyacrylic acid (PAA), cellulose preparation such as carboxymethyl cellulose (CMC) etc.Also add other composition such as preservative agent, softener, hygroscopic agent, anti-friction composition etc. in sizing liquor.The height of warp sizing rate and the quality of fiber, yarn count, density etc. are relevant, the fabric that yarn count is thin, density is large, and the warp sizing rate is high, the general fabrics rate of sizing 4%～8%.
The grey cloth spreading mass is unfavorable to dyeing and printing process, because the existence of slurry can be stain the dyeing and finishing working solution, expends and dyes material, even can hinder and dye contacting of material and fiber, affects the quality of dyeing and printing products.Therefore, fabric just must be processed through destarch at the beginning of dyeing and finishing processing, removes as much as possible the grey cloth spreading mass.It is different and different according to the kind of following process that destarch requires, and for example is used for the fabric of dyeing, stamp, and destarch is had relatively high expectations, and can slightly hang down the destarch requirement of BLEACHED FABRIC.
Warp thread institute spreading mass kind is relevant with the fiber species that fabric uses, and starch slurry is multiplex in cellulose base fiber fabric, and as COTTON FABRIC, linen etc., chemical sizwe is multiplex in closing fine fabric.Sometimes also use the mixed slurry starching.Destarch is to carry out destarch under desizing agent and certain effect condition.
