Example Embodiment

[0037] Example 1

[0038] A production method of 60S / 1 mercerized sliver includes the following processing steps:

[0039] 1. Pretreatment of cotton sliver: weigh 250g of cotton sliver, immerse it in water and apply pressure to fully soak the cotton sliver, and then put the cotton sliver into a dehydrator for dehydration, so that the liquid rate of the cotton sliver is controlled at 50%;

[0040] 2. Shake cotton sliver: shake the wet cotton sliver on a yarn shaker into 250g, the frame length is 120cm;

[0041] 3. Wrapping cloth: Wrap the twisted cotton sliver in a polyester woven fabric, where the width of the wrapper is 120cm and the unfolded length is 57cm, such as figure 1 As shown in the figure (1 is the wrapping cloth, 2 is the twisted cotton sliver), a wrapping method of one bottom layer and two layers on the upper layer is adopted;

[0042] 4. Mercerizing: the skein mercerizing machine adopts concentrated alkali spraying and instant squeezing for mercerizing. The alkali concentr...

Abstract

Disclosed are a cotton sliver mercerizing process and a mercerizing device utilizing the same, which belong to the technical field of textile technology. The cotton sliver mercerizing process includes: a, cotton sliver pretreatment step including dewing cotton slivers and dewatering the same or squeezing water out of the same to form wet cotton slivers with certain liquid content; b, a cotton sliver reeling step including reeling the wet cotton slivers on a reeling machine and fixing the cotton slivers by lay bands; c, a covering step including wrapping the reeled cotton slivers with the wrapping cloth integrally; and d, a mercerizing step realized by concentrated spraying and instant squeezing. The sliver cottons are mercerized effectively by dewing to reinforce and by means of concentrated spraying and instant squeezing, and alkali content of the cotton slivers is controlled all the time, so that the cotton slivers cannot be dissolved due to excessive swelling, and the difficult problem of failure in mercerizing the cotton slivers without twist is solved. In addition, the mercerized cotton slivers are bright, smooth and fluffy, and dye color yield is increased by 20%-30%.

Description

technical field [0001] The invention relates to a method for mercerizing cellulose fibers and a mercerizing device thereof in the technical field of textiles, in particular to a method for mercerizing cotton slivers and a mercerizing device thereof. Background technique [0002] Mercerizing means that the yarn or sliver is endowed with a certain stretching tension under the action of concentrated alkali to make it irreversibly swell, so that the cross-section of the fiber changes from oblate to circular, and the degree of orientation is improved, so that the fabric after mercerizing or The process of improving yarn tenacity, surface luster, color yield and fabric dimensional stability. Since the sliver itself has no strength after it is off the machine, it is formed only by the uneven arrangement of the fibers, so it is impossible to use shaking and skein mercerizing, so that the sliver cannot be effectively mercerized. According to patent information, cotton slivers are us...
