Embodiment 1

[0017] Dimension Removal Processing of Super High Count Wool Fabric

[0018] Select superfine wool with a quality count of 130, and spin it into 2.85×2 Tex double-ply yarn according to the ratio of wool:water-soluble PVA of 60:40. After the yarn is woven and repaired, it is processed for de-dimensionalizing. Due to the high content of water-soluble vinylon fiber, the fibers and yarns are very thin, the number of intervals for de-dimensionalizing is selected as 6 times, and the open-width de-dimensionalizing 6 cooking and 5 storing processes are adopted. The process flow is:

[0019] After raw and repaired, the gray fabric undergoes one cooking, one storage, two cooking, two storage, third cooking, third storage, fourth cooking, fourth storage, fifth cooking, fifth storage, sixth cooking, and then drying to obtain the fiber-removed fabric. (Yibo means one open-width continuous cooking, one save means one reel storage, and so on.)

Embodiment 2

[0024] Removal and Processing of High Count Elastic Cotton Fabric

[0025] Select fine-staple cotton with a fineness of 0.15 Tex, process it into roving according to the ratio of cotton: water-soluble PVA of 80:20, and spin it into 7.35 Tex ( 230.4 Ne) high count cotton type elastic corespun yarn. The yarn is weaved, repaired, and processed for de-dimensionalization. The number of intervals between dimension removal is selected as 5 times, and the technology of flat-width high-temperature dimension reduction, 5 boiling and 4 storage is adopted. The process flow is:

[0026] The raw and repaired gray cloth is subjected to the first cooking, first storage, second cooking, second storage, third cooking, third storage, fourth cooking, fourth storage, and fifth cooking, and then drying to obtain the fiber-removed fabric.

[0027] Open-width continuous cooking process: 8 pieces of gray cloth blended with cotton and vinylon are sewn together, and the leading cloth is continuously ...

Embodiment 3

[0031] Silk wool fabric dedimensional processing

[0032] Select 70 counts of wool and 0.17Tex (1.5D) mulberry spun silk fine dry cotton, according to the ratio of wool: silk: water-soluble PVA 75:15:10, spinning and processing into 13.9× 2 Tex (72 Nm / 2) double ply silk wool yarn. After the yarn is woven and repaired, it is processed for de-dimensionalizing. Due to the high content of water-soluble vinylon fiber, the fibers and yarns are very thin, the number of times of de-dimensionalizing gaps is selected as 4 times, and the open-width high-temperature de-dimensionalizing, 4 boiling and 3 storing processes are adopted. The process flow is:

[0033] The raw and repaired gray cloth is subjected to the first cooking, the first storage, the second cooking, the second storage, the third cooking, the third storage, and the fourth cooking, and then drying to obtain the fiber-removed fabric.

[0034] Open-width continuous cooking process: 6 pieces of gray cloth blended with silk ...

Abstract

The invention discloses an open width vinylon dissolution method which is characterized by including the steps as follows: conducting open-width continuous crabbing on blended greige cloth of fur, cotton and fibers after raw finish by an open-width continuous crabbing machine, then winding the open width of the textile on a scroll, storing the scroll for certain time, alternately repeating the steps of open-width continuous crabbing and scroll storing, and after the last open-width continuous crabbing, directly drying the greige cloth instead of scroll storing so as to obtain the textile after vinylon dissolution. With the method, soluble fiber is swelled, puffed, shrunk and dissolved completely; thoroughly vinylon dissolution is ensured; the surface of the textile after vinylon dissolution is flat, and smooth and glutinous but no mushy in handfeel; and all the indexes of warp-weft directional tensile breaking strength, warp-weft directional tearing strength and the like of the textile can meet the requirements of corresponding national standards.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing engineering applications, and in particular relates to a method for reducing dimensionality in open width. Background technique [0002] In recent years, high-count and thin textile and garment products have become more and more popular among consumers. On the existing ring spinning equipment, use high-count raw materials to spin ultra-high-count yarns (wool yarn 120 and above, and cotton yarns to 120 and above) yarns, use mid-range raw materials to spin high-count wool cotton yarns, and use water-soluble vinylon Spinning is one of the effective ways. In the process of processing high-count and light fabrics with water-soluble vinylon companion spinning, the fiber removal of fabrics, that is, vinylon dissolution treatment, is a very important process. At present, the weaving process is mainly carried out on the tweed machine and the piece dyeing machine. Due to the high tensi...
