    • The object of the invention is to provide a discharging agent for fibers dyed with an indigo dye and/or a sulfide dye, which enables stable discharge printing treatment to give the fibers soft texture, bright coloration and contours, which also enables printing. The object was achieved by the following: (1) A discharging agent for a fiber dyed with an indigo dye and/or a sulfide dye, consisting of chlorite and a viscosity-increasing nonionic surfactant, (2) a discharging agent according to the item (1), wherein the viscosity-increasing nonionic surfactant is a nonionic surfactant having HLB of 15 or higher, (3) a discharge printing process of a fabric or a sewing product dyed with an indigo dye and/or a sulfide dye, characterized in that a discharging agent having an adjusted pH of 7-12 and consisting of chlorite and a viscosity-increasing nonionic surfactant is printed on or applied to the fabric or the sewing product, followed by the application of a heat treatment, and (4) a discharge printing process according to the item (3), wherein the discharge printing treatment is performed simultaneously with, before, or after a coloring treatment.
    • 本发明的目的是提供一种用靛蓝染料和/或硫化染料染色的纤维的排出剂,其能够进行稳定的放电印刷处理,以使纤维具有柔软的质感,明亮的着色和轮廓,这也能够进行印刷。 该目的通过以下方式实现:(1)用亚氯酸盐和增粘非离子表面活性剂组成的用靛蓝染料和/或硫化物染料染色的纤维的排出剂,(2)根据该项目的排出剂 (1),其中增粘非离子表面活性剂为HLB为15以上的非离子表面活性剂,(3)用靛蓝染料和/或硫化染料染色的织物或缝合产品的放电印刷法,其特征在于 将调整pH为7-12的由亚氯酸盐和增粘非离子表面活性剂组成的排出剂印刷在织物或缝制产品上或施加到织物或缝合产品上,然后进行热处理,和(4) 根据(3)所述的放电印刷方法,其中所述放电印刷处理与着色处理同时进行,之前或之后进行。

    • A recycling process for liquid treatment of denim scrap comprising placing denim scrap on a support surface to form a thickness of flat, layered denim scrap. To the top surface is applied a compression plate to form the thickness of denim scrap into a compact cake. Then treatment liquid is passed through the interior of the compact cake in a direction parallel to the surfaces of the scrap, the liquid passing between opposed surfaces of the denim pieces. The denim scrap is preferably cut into relatively uniform sizes having their largest dimension less than about 4 inches. The treatment liquid can be a solvent for oxidized indigo dye, whereby indigo dye is removed from the denim scrap by said liquid; an aqueous solution containing a desizing agent, whereby size is removed from the denim scrap pieces; an aqueous solution containing a reducing agent for indigo dye, whereby dye in the denim pieces is reduced to a soluble, leuco form, dissolves in the solution, and both size and dye are removed from the denim scrap pieces; a solution containing desizing and reducing agent, whereby size and dye is removed from the denim scrap pieces; or an aqueous solution containing a reducing agent for indigo dye, whereby dye in the denim pieces is reduced to a soluble, reduced form, dissolves in the solution, and is removed from the denim scrap pieces; or a sequences of these liquids.
    • 用于牛仔废料的液体处理的回收方法包括将牛仔布废料放置在支撑表面上以形成平坦的分层牛仔布废料的厚度。 向顶面施加压缩板以将牛仔布废料的厚度形成紧凑的饼。 然后处理液体沿着平行于废料表面的方向通过压块的内部,该流体通过牛仔布片的相对表面之间。 牛仔布废料优选切割成具有小于约4英寸的最大尺寸的相对均匀的尺寸。 处理液可以是用于氧化靛蓝染料的溶剂,其中通过所述液体从牛仔布废料中除去靛蓝染料; 含有脱浆剂的水溶液,由此从牛仔布废料中除去尺寸; 含有靛蓝染料的还原剂的水溶液,由此将牛仔片中的染料还原成可溶的无色形式,溶解在溶液中,并从牛仔布废料中除去尺寸和染料; 包含脱浆和还原剂的溶液,其中从牛仔布废料中除去尺寸和染料; 或含有靛蓝染料的还原剂的水溶液,由此将牛仔片中的染料还原成可溶的还原形式,溶解在溶液中,并从牛仔布废料中除去; 或这些液体的序列。
