Description
Technical field
The invention belongs to textile dyeing and finishing manufacture fields, and in particular to a kind of desizing method of fabric.
Background technology
The desizing processing of traditional textile printing and dyeing refers to the technique for removing appended impurity on textile sizing material and fabric fibre
Process, wherein on fabric slurry (mainly have Starch Size, polyvinyl alcohol, polyacrylic size etc., after warp yarn sizing,
Slurry can form layer of surface in yam surface relatively smooth, compact structure and hydrophobic serous coat) it can be influenced in dyeing and finishing process
The wetability of fabric hinders the dyestuffs such as chemicals to contact fabric, therefore fabric must all carry out desizing processing before dyeing and finishing.
The method of desizing processing mainly has enzyme desizing, alkali desizing and oxidant desizing etc. at present, and desizing processes include mainly
Swelling, dissolving and the washout of slurry, fine and close serous coat existing for fabric surface considerably increase the difficulty that slurry is stripped from fabric.
For most of slurries, alkali desizing method is widely used method, in order to improve desizing, kiering efficiency, sodium hydroxide, refining
Agent, bleeding agent etc. are widely used, and then by slurry swelling, washout in desizing liquid, while removing most of impurity, and a large amount of
The slurry that the chemicals such as the sodium hydroxide used and polyvinyl alcohol etc. are difficult to degrade is present in desized wastewater, causes pole
Big environmental pollution.In dyeing waste water, the COD quantity that pre-treatment waste water generates accounts for the 60-70% of total COD discharge capacitys,
Middle desizing about accounts for 80%, that is to say, that in total COD discharge capacitys of printing and dyeing mill, desizing accounts for 50-55%.Therefore, improvement is knitted
Object desizing link and then reduction COD discharges, reduce energy consumption, have to energy-saving, the reduction pollution of entire dyeing
Significance.
Currently, plasma treatment technique is applied in desizing method, i.e., fabric is first carried out at plasma
Reason is placed in progress desizing processing in desizing liquid again, can help to reduce the dosage of chemicals in desizing liquid by the method, reduces
The discharge capacity of pollutant can also aid in and promote desizing rate, however, that there is processing procedures in its application process is discontinuous, i.e.,
Corona treatment and desizing liquid processing desizing substep are completed, and intermittent processing is so that production efficiency is low, and cost is higher, extremely
It is unfavorable for industrialized production.
Invention content
The technical problem to be solved by the present invention is to overcome deficiency in the prior art, a kind of moving back for improved fabric is provided

Specific implementation mode
Currently, the method for using corona treatment fabric is had existed in the desizing method of fabric in the prior art,
But consecutive production is cannot achieve, if however, directly will by deflector roll by apparatus for processing plasma and desizing processing procedure
The two connects and then realizes that the fabric after corona treatment is directly entered progress desizing processing in desizing liquid, and with this company of realization
Continuous property processing, as a result, desizing rate is unsatisfactory, it is difficult to meet current demand.It is found by numerous studies：Why
The reason of above-mentioned phenomenon occur is, corona treatment is required to handle for a long time as far as possible and be moved back with being promoted with desizing liquid processing
Effect is starched, but the hydrophilic radical formed after corona treatment is unstable, and under its effect meeting gradually with the passing of time
Drop, i.e., since continuous production requires corona treatment as the speed that fabric in desizing processing procedure moves so that moving back
Slurry effect is difficult to meet the requirements；Based on this discovery, if the regain of fabric 1 and fabric 1 move before plasma processing
Speed is effectively controlled, and the environmental condition that fabric 1 moves between control corona treatment and desizing processing (is kept
It is dry, it is preferably dried at 30-75 DEG C, can greatly delay the free radical isoreactivity particle generated in plasma treatment
Decaying) so that plasma is modified the surface of fabric the stability for more thoroughly enhancing hydrophilic radical in turn, further
Extend the time that high wettability is kept in desizing processing of fabric 1, then can it is expected to solve the problems, such as that desizing rate is undesirable.
The technical issues of based on above-mentioned discovery, the present invention provide a kind of desizing method of fabric, and the desizing method includes
Following steps：Corona treatment is carried out during so that pending fabric 1 is transmitted on the transfer mechanism successively, at drying
Reason and desizing processing；Wherein, the regain that the fabric 1 is controlled before carrying out the corona treatment is 3-8%, described
The speed that fabric 1 moves in the transport mechanism is 50-70m/min, in the drying and processing control by it is described it is equal from
The regain of the processed fabric of daughter 1 is 2-7%.
It according to the present invention, transport mechanism, such as can be the transport mechanism that multigroup transfer roller 9-1 is constituted so that fabric 1
It is moved in transfer roller 9-1, the transmission that fabric 1 then can be realized by the cooperation of unreeling structure and winding mechanism is moved, this
Invention is not specifically limited herein, can be transmission equipment commonly used in the prior art.
According to the present invention, as shown in Figure 1, before fabric 1 can first pass through the progress corona treatment of regain pretreatment unit 2
Regain control, then by bi-medium to block Asia glow discharge atmospheric pressure plasma device 3 carry out corona treatment,
The regain of fabric by the control of drying unit 4 after corona treatment again, soaks then in turn through the first desizing liquid
Groove 5-1 ..., the 7th desizing liquid pad slot 5-7, the 8th desizing liquid pad slot 5-8 carry out kiering processing, pad processing (can be with
Realized by roll), finally distinguish successively in steaming device 6, hot water cleaning device 7 (preferably including multiple), cold water cleaning device 8
Carry out individual composition (steaming time is preferably 25-40min), hot water wash processing (temperature is 60-90 DEG C), cold washing process (temperature
Degree is 15-30 DEG C), you can it completes the desizing to fabric 1 and handles.
According to the present invention, the corona treatment is to be filled by bi-medium to block Asia glow discharge atmospheric pressure plasma
Set 3 progress, wherein working gas is one or more of air, argon gas, helium, nitrogen and oxygen, the flow velocity of working gas
