Abstract

The present invention relates to fabric producing technology, and is especially process of producing knitted denim. The present invention has softening treatment on the yarn via adding assistant during the indigo reducing dyeing course, and several times of softening treatment and hot settling in the dewisting course and the post-finishing course, so that cheap ring yarn may be used in producing knitted denim for lowering production cost. The produced knitted denim has stable elasticity, high wash ability, high wrinkle resistance, high permeability and soft handing and is ideal fabric for making high grade costume, especially sports wear, etc.

Description

The production method of knitted denim

Technical field

The present invention relates to textiles manufacturing technology field, especially a kind of production method of knitted denim.

Background technology

Traditional denim adopts the splitting spinning of textile ring to form through volume, and it has, and style is rough, lining stiffening, gas permeability is poor, contain characteristic such as Bai Xin, is used to make fitted pants and overcoat, can not be used to make underwear.Traditional tWeft Knitted Fabrics adopts the open-end spinning weft-knitting to form, and has characteristics such as softness, ventilative, comfortable, no white core and elastic force are big, is usually used in making underwear.Along with the development of society, the raising of living standards of the people, to dress ornament follow the fashion, unique, clear-cut individuality, therefore garment material is also required diversity.In recent years, people have developed and integrated the knitted denim that cowboy style is arranged in traditional tWeft Knitted Fabrics, the style that its existing denim is rough, and lining softness, good permeability, comfortable and easy to wear, endure with all one's will appropriateness and, still have the characteristics of the white core of denim, be high-grade underwear fabric through the broadwise elasticity stable.The common open-end spinning twist that is used to make traditional tWeft Knitted Fabrics is little, pliability good, but that it is done is poor, filoplume is many, can not be used to make knitted denim, for reaching the requirements of weaving process of knitted denim, usually adopt raw cotton to do the open-end spinning of raw material, to improve the intensity of yarn, this open-end spinning price is higher.And the ring that is used to make traditional denim splits that the spinning bar makes a good job of, filoplume is few, cheap, but the spinning twist is big because ring splits, pliability is poor, and is also inapplicable in the manufacturing technique of existing knitted jean.

Summary of the invention

The technical problem to be solved in the present invention is: a kind of method of the knitted denim that spinning produces that adopts cheap ring to split is provided, solves the open-end spinning that existing knitted denim must adopt the higher raw cotton of price to make raw material and produce knitted denim, the high problem of production cost.

The technical solution adopted for the present invention to solve the technical problems is: a kind of production method of knitted denim has following processing step:

A. warping: to the cotton textiles ring spinning warping machines warping of splitting;

B. dyeing: carry out pencil indigo reduction stain with the spinning of splitting of the cotton textiles ring of dyeing machine after, add Tissuemat E class, quaternary ammonium salts or polyvinyl acetate class dyeing assistant during dyeing yarn is carried out soft treatment to warping;

C. lease making: with the yarn lease making of leasing machine after to dyeing;

D. a system tube untwisting: with the untwisting of system tube untwisting machinery system tube, make that aberration is little end to end, COLOR FASTNESS strong, do not have broken end, even tension, be applicable to the woven indigo cheese of knitted jean;

E. weave cotton cloth: cut open the width of cloth after indigo cheese is fed the knitting weft knitting of knitting weft machine;

F. carry out the back arrangement with padding machine: 1. advance cloth, the cloth that weaves is advanced cloth rewinder roll and divides roll dies to advance cloth and flattening through padding machine, padding machine pressure is 3Kg; 2. soft, the cloth of flattening immerses the padding machine tank that contains softening agent, and softening agent is that 4～6% fatty acid acyl amine nonionic softener adds 94～96% water, and the temperature of softening agent is 55 ℃～65 ℃; 3. tiltedly whole, tiltedly whole through the cloth of soft treatment through whole cross roll; 4. flatten, the cloth after the whole tiltedly processing is flattened through minute roll dies; 5. typing is carried out HEAT SETTING to the cloth after flattening, and 6. oven dry is dried processing to the cloth of HEAT SETTING, and oven temperature is 150 ℃～200 ℃; 7. cooling;

G. repeat f step 1～4 time;

H. detect packing.

The invention has the beneficial effects as follows, the present invention adds dyeing assistant yarn is carried out soft treatment in pencil indigo reduction stain process, in conjunction with adopting repeatedly soft treatment and HEAT SETTING in system tube back untwisting technology and the postfinishing process, thereby can utilize the spinning of splitting of cheap ring to produce knitted denim, greatly reduce production cost, and the knitted denim of being produced is through the broadwise elasticity stable, water-fastly wash crease-resistant folding, good permeability, soft, it is the desirable lining of making the elaboration clothes, wear cool and comfortable, be specially adapted to the high strength activity, sports, manual labor, dress when going on business or travelling.

The specific embodiment

Embodiment one:

A kind of production method of knitted denim has following processing step:

A. warping: to the cotton textiles ring spinning warping machines warping of splitting;

B. dyeing: carry out pencil indigo reduction stain with the spinning of splitting of the cotton textiles ring of dyeing machine after, add the Perapret PE-2 that dyeing assistant polyvinyl acetate emulsion BASF Aktiengesellschaft produces during dyeing yarn is carried out soft treatment to warping;

C. lease making: with the yarn lease making of leasing machine after to dyeing;

D. a system tube untwisting: with the untwisting of system tube untwisting machinery system tube, make that aberration is little end to end, COLOR FASTNESS strong, do not have broken end, even tension, be applicable to the woven indigo cheese of knitted jean;

E. weave cotton cloth: cut open the width of cloth after indigo cheese is fed the knitting weft knitting of knitting weft machine;

F. carry out the back arrangement with padding machine: 1. advance cloth, the cloth that weaves is advanced cloth rewinder roll and divides roll dies to advance cloth and flattening through padding machine, padding machine pressure is 3Kg; 2. soft, the cloth that flattens immerses the padding machine tank that contains softening agent, softening agent is that 6% fatty acid acyl amine nonionic softener (Belsoft 200 that Shanghai Henkel grease chemical article Co., Ltd produces) adds 94% water, and the temperature of softening agent is 55 ℃～65 ℃; 3. tiltedly whole, tiltedly whole through the cloth of soft treatment through whole cross roll; 4. flatten, the cloth after the whole tiltedly processing is flattened through minute roll dies; 5. typing is carried out HEAT SETTING to the cloth after flattening, and 6. oven dry is dried processing to the cloth of HEAT SETTING, and oven temperature is 150 ℃～200 ℃; 7. cooling;

G. repeat f step 1 time;

H. detect packing.
