Embodiment 1

[0030] Embodiment 1 A kind of production method of sponge towel yarn

[0031] Include the following steps:

[0032] 1. Raw material selection

[0033] ① Cotton, machine-harvested Xinjiang cotton, color characteristic grade 31, length 28.00mm, micronaire value 4.66, fineness 5413 metric, single fiber breaking strength 29.52cN / tex, uniformity 81.81%, short fiber 11.3%, moisture regain 6.93%, containing 1.7% impurities;

[0034] ②Water-soluble vinylon, linear density 1.33dtex, length 38.00mm, dry breaking strength 5.14cN / tex, defect: 0.65mg / 100g, moisture regain 3.99%, dissolution temperature in water 85℃.

[0035] 2. Cotton raw material yarn making

[0036] (1) Pre-treatment of cotton raw materials

[0037] Cotton raw materials enter the drawing process through the opening and cleaning process, carding process, and combing process. According to the combed sliver fiber hook and drafting theory, it is based on the principle of improving evenness and strength.

[0038] (2) Dra...

Embodiment 2

[0076] Example 2 After the sponge towel is made into a towel from yarn, the fiber removal test is carried out

[0077] After de-dimensionalizing, the remaining cotton fiber single yarn changes back to the original "S" twist direction, and the remaining twist is the twist difference between the single yarn and the two-for-one twist;

[0078] Adjust the size of the friction surface between the dragon belt and each spindle disc, the distance between the cradle and the roller head, and reduce the difference in twist between the spindles. Two-for-one twisting designs three different twists for experiments. After the towel is made, the remaining twist and other indicators of the towel are tested as follows:

[0079]

[0080] The finished product quality feel and hygroscopicity of the second group, thickness increase after washing and other indexes are all better than the first group and the third group, so the two-for-one twist degree of the second group is 44.5 twists / 10cm is th...

Abstract

The invention provides a method for producing yarn used for sponge towels. The method for producing yarn used for sponge towels comprises steps of yarn production through cotton raw materials, yarn production through water soluble vinylon, and two-for-one twisting. With respect to the yarn used for sponge towels, the yarn quality indexes are that the evenness CV is 7.50%, the yarn contains zero thin place per km, zero thick place per km and one nep per km, the degree of twist is 44.5 twisting / 10 cm, the average strength is 1489 cN, the weight cv is 1.4 %, the yarn contains 12.03 hairs having the length of 3-9 mm per m, and the hairiness index H value is 2.28. The towel prepared by the yarn used for sponge towels is soft and comfortable, and the degree of twist is low and is 33.2-44.6 twisting / 10 cm; the towel is good in hygroscopicity, and the water absorption rate is 380%; drip diffusion time is 0.5 s, the wicking height is 260 mm, after the towel is washed every time, the degree of twist is reduced, the more the towel is washed, the fluffier the towel is, and the better the effect is.

Description

technical field [0001] The invention relates to a method for producing sponge towel yarn, which belongs to the technical field of textiles. Background technique [0002] Towel products are mainly towels, and also include bath towels, towel quilts, bathrobes, nightgowns, etc. These products are not only daily necessities, but also decorative items. Its requirements for yarn are: small twist, good color, soft hand feeling and high elasticity. Therefore, there are particularities in the selection of spinning raw materials and the process configuration of each process. At present, people are more and more pursuing the comfort of daily necessities. The towels made of ordinary towels and yarns have average softness and tend to harden after repeated washing, so the comfort is out of the question. [0003] The recent untwisted towel yarns are relatively fluffy and soft, but have the following defects: [0004] (1) The yarn has no twist, low strength and many hairiness; [0005] ...
