Description

Production method of fluffy and soft terry fabric with imitated cut velvet effect

Technical Field

The invention belongs to the field of textile products, and particularly relates to a production method of a fluffy and soft terry fabric with a velvet cutting-imitated effect.

Background

Towel products are daily textiles with a large range. The development of more and more new design towels enriches the market of people, wherein the cut velvet type towels are gradually paid attention to and loved by market consumers in recent years due to the special velvet effect and soft and comfortable performance of the cut velvet type towels, but more shedding hairiness easily occurs in the washing process of the towels made of the existing cut velvet type products, and the use of the consumers is seriously affected.

Therefore, how to overcome the above-mentioned defects of the existing cut pile towel and terry cloth is one of the problems to be solved in the art.

Disclosure of Invention

Aiming at the problems in the prior art, the invention provides a production method of fluffy and soft terry fabric with a cut velvet hand feeling effect, the terry fabric is single-sided or double-sided terry fabric, the terry fabric is woven by a towel loom or a warp knitting towel loom, a half blank of the terry fabric has the hand feeling similar to a cut velvet product after being treated by a special dyeing and finishing process, and the hairiness rate after 5 times of washing is less than 5 per mill.

The invention adopts the following technical scheme:

a production method of fluffy soft terry fabric imitating a cut pile hand feeling effect, wherein the terry fabric is a single-sided or double-sided terry fabric;

the specific production steps are as follows: wherein the percentages are weight percentages;

1. preparation of yarn:

(1) The terry yarn of the terry fabric is a blended yarn of water-soluble vinylon (PVA) and cotton fiber or other fibers, more preferably a blended yarn of water-soluble vinylon (PVA) and cotton fiber,

wherein the water-soluble vinylon comprises the following components: 3-15%, more preferably 5-10% of water-soluble vinylon, 95% -90% of cotton fiber or other fiber;

wherein the hot water melting point of the PVA fiber is 90-100 degrees, and the fineness of the water-soluble PVA fiber is as follows: 1.1-2.5dtex, the length of which is: 38mm; further preferred fineness is: 1.1-1.7dtex;

the other fibers are pure fibers of fibers such as lyocell, modal, regenerated cellulose fibers, acrylic fibers, terylene and the like or mixed fibers of the pure fibers and cotton fibers;

the blended yarn composed of the components is mainly used for better controlling the content of the water-soluble vinylon, under the content, the content of the water-soluble vinylon is prestretched firstly during dyeing and finishing treatment, so that the whole blended yarn is prestretched to generate a velvet cutting effect, the whole terry fabric can maintain the velvet cutting effect after drying and shaping, the effect is not affected after the water-soluble vinylon is dissolved in the subsequent treatment, and the loss of the fiber in the whole treatment process is smaller according to the consumption of the water-soluble vinylon, so that the production cost can be reduced, and meanwhile, the better use effect is obtained;

(2) The terry yarn is a single yarn or a ply yarn:

if the terry yarn is a single yarn, the count is 6s to 32s, more preferably: 10s-16s; the single yarn twist factor is not higher than 290, more preferably not higher than 270;

if the terry yarn is a ply yarn, the single yarn count making up the ply yarn is 18s to 40s, more preferably: 21s-32s; the single yarn twist coefficient is not higher than 290, more preferably not higher than 270, the ply twist is not higher than 30 twist/10 cm, and the ply twist direction is opposite to the single yarn twist direction;

by adopting the lower twist, the terry after untwisting is softer, has better hand feeling and can obtain better use effect;

2. preparing a blank towel:

interweaving the terry yarn obtained in the step 1 with conventional pure cotton ground warp yarns and weft yarns to obtain towel blank towel, wherein the half blank terry height of the towel fabric is not lower than 8cm/10 terry and not higher than 14cm/10 terry; further preferably, the height of the semi-blank loop is not less than 10.5cm/10 loops and not more than 12.5cm/10 loops;

3. dyeing and finishing:

and (3) obtaining the cut pile-imitating terry fabric by using the blank towel obtained in the step (2) and adopting the dyeing and finishing process as follows:

(1) Pre-wetting padding treatment is carried out on the pile semi-blank product, so that smooth and tidy pile is obtained after dyeing and finishing treatment;

(2) Filling the blank towel in the step (1) into an overflow machine, adding 1-2g/L of NoveXin alpha amylase into the blank towel at the bath ratio of 1:10 at 75-85 ℃, and carrying out desizing and terry preshrinking on the blank towel for 20-30min; drying after dehydration to obtain a preshrinking blank towel;

(3) The blank towel obtained in the steps is reloaded into an overflow machine, and the bath ratio is 1:10 under the alkaline high-temperature condition, and the steps are adopted: chelating agent DM-8108 (Shandong Demei fine chemical Co., ltd.): 1-2g/L hydrogen peroxide (mass ratio of 27.5% in Bojian chemical industry), 3-12g/L hydrogen peroxide stabilizer TF-122 (produced by Zhejiang Chen chemical Co., ltd.) 0.3-1g/L, and ionic membrane caustic soda (mass ratio of 32.5% in Lizhou chemical industry Co., ltd.): 5-10g/L, high concentration refining agent TF-125 (manufactured by Zhejiang Chemie Co., ltd.): boiling, bleaching and dimension removing are carried out at 0.5-2g/L, the pH value in the system is 12-14, and the temperature of the boiling and bleaching is 95-105 ℃; the running time is 30-90min, more preferably 60min;

after the hot washing, the pH value is regulated to 6.5-7.5, and then deoxidization treatment is carried out under the condition of 0.001-0.01g/L of deoxidizing enzyme;

then, dyeing is carried out under the weak alkaline condition with the pH value of 10-13;

finally, adjusting the pH value to be between 4.0 and 6.5 by using 80 percent glacial acetic acid,

polishing with 0.05-0.5% biological enzyme, softening, dewatering, stoving and sewing to obtain the final product.

In the above treatment process, the steps after the heat washing are all conventional production steps in the art, which are not repeated by the inventor, and the skilled person can adapt according to specific process requirements.

The towel obtained by the preparation process has the advantages that the water-soluble vinylon is prestretched during dyeing and finishing treatment, so that the whole blended yarn is prestretched to generate a velvet cutting effect, the whole terry fabric can maintain the velvet cutting effect after drying and shaping, and finally the towel obtained by the preparation process has the hand feeling of a velvet towel product, and the terry has rebound resilience, but the yield of the velvet product is relatively high, and the fiber loss is less; and the hairiness of the final product towel after washing is 20-30% lower than that of a common hairiness-cutting towel, the use comfort is obviously better than that of a common hairiness-cutting product, the hairiness rate is 10-20% lower than that of a conventional towel, and the hairiness rate after washing for 5 times is not higher than 5 per mill.
