Abstract
A kind of pre-processing device of dyeing line, for desizing, refining and bleaching, including pond body, stretch tight cloth roller and power set；The pond body is made up of insulating materials, NaCl solution is marked with pond body, two taut cloth rollers are provided with the pond body, stretched tight between two taut cloth rollers and need desizing, the cloth of refining and bleaching, the taut cloth roller is immersed in NaCl solution, the taut cloth cylinder surface is the conductive material of electrochemicaUy inert, two taut cloth rollers are connected with the positive pole of power supply with negative pole respectively, and the power set are connected with taut cloth drum drive, drive taut cloth roller to rotate.By electrolysis of the anodic-cathodic to NaCl solution, NaOH and oxide are generated, is fed intake and production procedure simplifying.Meanwhile the production line, in whole work process, the every biochemical indicator for producing sewage produces the index of sewage significantly lower than existing production line, greatly reduces the cost of sewage disposal.
Description
Technical field
The present invention relates to the production line of caused by spinning industrial production, more particularly to the desizing of fabrics printing and dyeing pre-treatment, it is concise and
Bleaching line, and printing and dyeing production pre-processing device.
Background technology
Dyeing is largest, basic preferable, time-honored main industries in China's textile industry, in China
There is the developing history of last 100 yearses.The dye material kind and quantity that dyeing uses are most.Due to printing and dyeing kind contain it is a large amount of
Natural impurity can influence the quality of following process process and product, it is necessary to be removed using chemical method.
In the prior art, the process of scouringing and bleaching of textile dye transfer pre-treatment includes desizing, concise and bleaching three process.
In weaving, for warp thread because opening and the effect of throwing a spear are by larger tension force and friction, often generation is disconnected through phenomenon, is
Disconnected warp is reduced, improves the strength, wearability and smooth degree of warp thread, ensure to weave cotton cloth is smoothed out, warp thread one before weaving
As will pass through starching handle.Warp sizing is convenient to be weaved, but brings many difficulties to dyeing and printing process, and it not only influences fabric
Permeability, the contact of chemical agent and dyestuff with fiber is hindered, it is consume dye chemical drug product more, it can also influence product quality.So
Cotton will carry out desizing before scouringing and bleaching.Desizing not only can remove the slurry on cotton, and can also remove the part day on cotton fiber
Right impurity.
Cotton, although most of slurry and fraction natural impurity have removed, remains after desizing
Most of natural impurity, such as waxy substance, pectin substance, nitrogen substance, cotton seed hulls and part finish and a small amount of slurry, these
The presence of impurity makes that bafta cloth cover is more yellow, poor permeability, it is impossible to meet the requirement of the following process such as dyeing, stamp, arrangement, because
This, will carry out kiering after desizing.Kiering is exactly chemically to remove the natural impurity on cotton, the mistake of concise purification cellulose
Journey.
Cotton is after kiering, although eliminating impurity to a certain extent, but still remains pigment, and dirty appearance is white,
The colour brightness of dyeing and PRINTED FABRIC is influenceed, therefore need to be bleached.The purpose of bleaching mainly removes natural pigment, assigns
Cotton is given with necessary whiteness, while can also further remove the other impurities remained on cotton, improves its wettability.
In the pre-treatment of textile dye transfer at present, desizing, concise and bleaching three process are respectively during three independence
Complete.The shortcomings that this technique is：Process is complicated, equipment flowing water line length, energy consumption are big, activity duration length, containing big in working solution
The caustic soda of amount, bleaching agent, stabilizer etc., waste discharge toxicity is big, and environmental pollution is serious, and intractability is high.
The production line merged on a small quantity to desizing, concise and bleaching three process existing at present, by desizing, concise and bleaching phase
With reference to, processing link is reduced, energy-saving and water-saving, people from province is laborsaving, improves processing efficiency, but because working solution equally burns containing substantial amounts of
Alkali, bleaching agent, stabilizer, there is also waste discharge toxicity is big, environmental pollution serious situation.
The content of the invention
For this reason, it may be necessary to a kind of simple easily implementation is provided, it is environment amenable that desizing, the pre- place of concise and bleaching are carried out to cloth
The dyeing line of reason and the pre-processing device for production of printing and dyeing.
To achieve the above object, a kind of dyeing line is inventor provided, the dyeing line handles work along cloth
Sequence includes equipment of singing, pre-processing device, mercerizing machine, dyeing and printing equipment, rear finishing equipment successively；
The pre-processing device is used for desizing, and refining and bleaching, the pre-processing device include pond body, stretch tight cloth roller and
Power set；
