Problems solved by technology

[0003] The invention provides a production method of mercerized cellulose fibers and a mercerizing device thereof, which effectively mercerizes the sliver by adopting the method of increasing the strength of the sliver to wet, concentrated spraying and instant extrusion, and always controls the amount of alkali on the sliver , will not cause excessive swelling and melting of the cotton sliver, which solves the problem that the cotton sliver cannot be mercerized in the state of no twist, the mercerized cotton sliver has bright luster, fluffy hand feeling, and the dyeing yield increases by 20% to 30%.

Embodiment 1

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

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

[0040] 2. Rocking cotton sliver: twist the wet cotton sliver on the spinning machine into 250g, and the frame length is 120cm;

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

[0042] 4. Mercerizing: On the above-mentioned skein mercerizing machine, mercerizing is carried out by concentrated spraying of alkali and instant extrusion, wherein the concentration of...

Embodiment 2

[0053] A production method of 70S / 1 mercerized cotton sliver, comprising the following processing steps:

[0054] 1. Cotton sliver pretreatment: weigh 500g cotton sliver, immerse in water and apply pressure to make the sliver fully soaked, then put the sliver into a dehydrator for dehydration, so that the liquid-carrying rate of the sliver is controlled at 55%;

[0055] 2. Rocking cotton sliver: twist the wet cotton sliver on the spinning machine into 500g, and the frame length is 130cm;

[0056] 3. Wrapping cloth: Wrap twisted cotton sliver in polyester woven fabric, the width of the wrapping cloth is 130cm, and the unfolded length is 63cm. The bottom layer is wrapped in one layer and the upper layer is wrapped in two layers;

[0057] 4. Mercerizing: On the improved skein mercerizing machine, mercerizing is carried out by means of concentrated alkali spraying and instant extrusion, in which the alkali concentration is 28 degrees Baume, the time of alkali spraying and alkali e...

Embodiment 3

[0059] A production method of 80S / 1 mercerized cotton sliver, comprising the following processing steps:

[0060] 1. Cotton sliver pretreatment: weigh the sliver 1000g, immerse it in water and apply pressure to make the sliver fully soaked, then put the sliver into a dehydrator for dehydration, so that the liquid-carrying rate of the sliver is controlled at 60%;

[0061] 2. Rocking cotton sliver: twist the wet cotton sliver on the spinning machine to 1000g, and the frame length is 140cm;

[0062] 3. Wrapping cloth: Wrap twisted cotton sliver in polyester woven fabric, the width of the wrapping cloth is 140cm, and the unfolded length is 72cm. The bottom layer is wrapped in one layer and the upper layer is wrapped in two layers;

[0063] 4. Mercerizing: On the improved skein yarn mercerizing machine, concentrated alkali spraying and instant extrusion are used for mercerizing, in which the alkali concentration is 30 degrees Baume, the alkali spraying time is 160s, the stretching ...

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...
