Description
Technical field
The invention belongs to technical field of textile printing, and in particular to a kind of denim fabric green production process.
Background technology
Denim fabric has had the history of more than 100 years from invention beginning till now, develops by single breed structure
Superior, functionalization till now, diversification, have there is very big scale.As the improvement of people's living standards, to life
The requirement of quality is also higher and higher, especially in itself dress, living environment etc..In addition, as people's energy conservation and environmental protection is anticipated
The continuous reinforcement known, Green Textiles are corresponding to ecological spinning to be suggested, and this requires the links of textile industry will have
There is environment friendly.
Denim fabric production technology mainly includes warping, dyeing, starching（Also referred to as sizing）, weaving and final finishing.
Wherein, starching is that one kind prevents or reduce yarn generation broken end in weaving, improves the production link of working efficiency.
The main purpose of traditional starching is to increase yarn strength.However denim yarn is mostly thick Zhi Gaomi yarns, ultimate strength itself
Very high, the effect of starching is different from traditional sense, primarily to the wear-resisting property and submissive filoplume of increase yarn, are allowed to more preferable
Ground adapts to the abrasion to yarn in shuttleless loom high speed weaving process.
Therefore, the starching of denim yarn at present is substantially using composite mortar namely using Starch Size, polyethylene
Two kinds in alcohols slurry and acrylic size or three kinds, and slurry groove temperature is substantially all at 90 DEG C or more（In
State patent document CN103966849A, CN105908504A, CN106758317A）.
The shortcomings that this tradition denim yarn sizing technique, is：（1）The preparation of slurry and drying course are required to consume
A large amount of steam, steam consumption are larger；（2）Subsequent desizing arranging process needs the auxiliary agents such as a large amount of desizing enzymes, big so as to generate
The slurries waste water of amount, COD discharge capacitys are larger.This theme obviously with current textile industry energy-saving and emission-reduction is disagreed.
Invention content
It is an object of the invention to solve the above problems, one kind more supernumerary segment while with preferable starch finishing effect is provided
The denim fabric green production process of energy environmental protection.
Realizing the technical solution of the object of the invention is：A kind of denim fabric green production process, including warping, dyeing, on
Slurry, weaving and arrangement, it is characterised in that：For the slurry that the starching uses for single slurry, slurry groove temperature is room temperature（5~30
DEG C, similarly hereinafter）.
The single slurry is cationic polyacrylamide class slurry.
The cationic polyacrylamide class slurry is that cationic polyacrylamide is added to the water, heating stirring dissolving
It obtains.
The performance indicator of the cationic polyacrylamide is as follows：
Appearance：White particle；
Molecular weight：800~12,000,000；
Dissolution time：≤30min.
The warping is using pure cotton as raw material, with cotton spun yarn warping.
The dyeing is that the yarn after warping is dyed on ball warp dyeing machine using bipseudoindoxyl dye；Concrete technology is such as
Under：Wetting kiering together → washing two → eight indigo dyeings, eight ventilative oxidation → cold water wash together → warm water wash together →
Cold water washes the drying of two → cylinder.
The loom used of weaving is Toyota's air-jet loom or gamma loom.
The arrangement concrete technology is as follows：Singeing finish → desizing arrangement → mercerized finish → skews arrangement → sizing and arranges
→ shrunk finish → test package.
The desizing is arranged is washed using common warm water, without auxiliary agent.
The good effect that the present invention has：
（1）The present invention have been surprisingly found that can be at normal temperatures to jean yarn using single cationic polyacrylamide class slurry
Line carries out starching, and with preferable starch finishing effect.
（2）In terms of starch finishing effect, sizing technique of the invention can reduce the end breakage rate 5%~10% of yarn, Grade A
For rate up to 99%, other such as stop frequencies, hairiness index, elongation at break, woven efficiency and the prior art are substantially suitable.
（3）The present invention at normal temperatures carries out denim yarn starching and can be reduced needed for mashing off to avoid high temperature steam environments
Steam, the energy is not only greatly saved, but also the aging of sizing roller, squeezing roller can be reduced, improves its service life；It can also
Enough operative employee is avoided to scald, improve production security.Especially in subsequent desizing arrangement, helped without desizing enzyme etc.
Agent greatly reduces the pollution of slurries waste water.
（4）In terms of energy conservation and environmental protection, sizing technique of the invention can reduce water consumption 40% or so, reduce steam consumption 30%
Left and right, reduces COD discharge capacitys 40% or so, significantly mitigates denim fabric processing and is seriously polluted caused by environment, have it is water-saving,
Outstanding advantage in terms of energy saving, emission reduction, synergy can be accelerated to promote starching clean manufacturing paces, promote industry value chain.
Specific embodiment
（Embodiment 1）
The denim fabric green production process of the present embodiment has steps of：
1. using pure cotton as raw material, with sending dye slurry process after cotton spun yarn warping.
2. the yarn after warping is dyed on ball warp dyeing machine using bipseudoindoxyl dye.
