Embodiment

[0013] The pretreatment process of polyester acrylic hemp-cotton interwoven fabric in this embodiment includes the process steps of turning cloth → stitching → singeing → deboiling and unification → bleaching → drying → mercerizing → drying, and the singeing adopts one-time burning process. Mao, four craters, two fronts and two reverses, speed 120m / min; the concentration of caustic soda in the working fluid of the deboil-in-one is 16g / L; ℃, time 50min, after leaving the crawler box, wash three compartments with hot water at 90 °C, wash two compartments with cold water, and release the cloth; the bleaching uses hydrogen peroxide (100%) 8g / L, stabilizer EDTMP 2g / L, pH value 10.5 Cold rolling at the bottom, steaming at 95°C for 60 minutes; the alkali concentration of the mercerizing liquid for mercerizing is 150g / L.

Abstract

The invention discloses an acrylic polyester ramie cotton mixed fabric pretreatment process which comprises the following steps: turning cloth, sewing the end, singeing, desizing-scouring, bleaching, drying, mercerizing and drying, wherein the singeing step refers to one-step singeing, the four burners refer to two positive burners and two reverse burners, and the speed is 20m per minute; according to the desizing-scouring step, the caustic soda concentration in a working solution is 16g / L; according to the bleaching step, 6-8g / L of hydrogen peroxide (100 percent) is adopted, 2g / L of a stabilizer EDTMP is adopted, cold rolling is performed under the pH value of 10-10.5, and steaming is performed at the temperature between 90 DEG C and 95 DEG C for 60 minutes; and the concentration of alkali in a mercerizing solution in the mercerizing step is 140-160g / L. The singeing effect achieves a level 4; the desizing and scouring are combined into a process, the action time of acrylic fibers and strong base is reduced, and impurities on ramie cotton are effectively removed; and moreover, the acrylic polyester is not yellowed, and high strength is maintained.

Description

[0001] technical field [0002] The invention belongs to the technical field of textiles, and in particular relates to a pretreatment process of polyester acrylic linen-cotton interwoven fabric. [0003] Background technique [0004] Since polyester and acrylic are synthetic fibers, the alkali resistance and heat resistance of the two fibers are different; linen and cotton fibers are natural fibers, and their impurity content is also different. The fabric is complex. The conventional process is cloth turning→stitching→singeing→desizing→scouring→bleaching→drying→mercerizing→drying. There are defects such as excessive shrinkage of the door width, yellowing of polyester and acrylic fibers, and reduced strength. [0005] Contents of the invention [0006] The object of the present invention is to provide a pretreatment process for polyester acrylic hemp-cotton interwoven fabric, which can solve the problems existing in the prior art such as excessive width shrinkage, yellow...
