Description
Technical field
The present invention relates to the dyeing and finishing technique field, relate in particular to a kind of desizing method of fabric.
Background technology
The technical process that refers to remove appended impurity on textile sizing material and the fabric fibre is processed in the destarch of traditional textile printing and dyeing.The warp thread of the fabrics such as cotton, viscose glue and various synthetic fiber passes through mostly first sizing before weaving.Slurry in the sizing process can affect the wettability of fabric in dyeing and finishing process, and the obstruction chemicals contacts fiber.Therefore fabric is carrying out must carrying out the destarch processing before dyeing and finishing is processed.Desizing method commonly used comprises: alkali destarch method, enzyme desizing method, oxidant destarch method and alkaline oxygen bath destarch method.
Alkali destarch method is applicable to take starch or starch as the fabric main, that the rate of sizing is lower and the fabric of chemical sizwe (such as the polyacrylic slurry) and other slurry mixing starching.The advantage of this technique is that cost is low, and caustic soda can utilize kiering or mercerized waste alkali, does not damage again cotton fiber.But alkali destarch method is bad for the destarch effect of PVA slurry, and easily causes the PVA slurry that the slime spots that " cohesion " phenomenon sticks on the fabric or can form very difficult removal on the fabric guide roll occurs, and very easily produces the printing and dyeing fault; In addition, for the too late enzyme desizing method of the fabric alkali destarch effect of using the starch starching.Yet the enzyme desizing method is only applicable to pure starch slurry or take the fabric of starch slurry as slurry sizing main, that PVA content is lower.If mix PVA content fabric higher or that starch take the PVA slurry as the Your Majesty in the slurry, then must adopt other desizing method.Oxidant destarch method is applicable to PVA and closes fine blending and PURE YARN FABRIC take PVA as main and other slurry mixing starching, can strip all slurries.The oxidant that is used for destarch generally has sodium bromite, H
2O
2, NaClO, persulfate etc., at present main hydrogen peroxide and persulfate two classes of adopting.The characteristics of this technique are that destarch is rapid, and are effective, if also have the partial bleaching effect with the hydrogen peroxide destarch.The hydrogen peroxide destarch is not only to various types of starch, and the PVA slurry is also had preferably destarch effect, but to be high expensive, technology controlling and process bad easily goes out oxidation hole problem for the shortcoming that exists.If when adopting the persulfate destarch cellulose fibre is had damage, fabric falls strong serious, and the destarch effect of PVA is short of to some extent.
Because the scope of application of above-mentioned desizing method is narrower and have a more shortcoming, therefore, at present in industrial production take alkaline oxygen bath destarch method as main, this be since the method major advantage to be cost low and help the removal of cotton seed hulls and part fiber commensal, alleviate concise burden, semi-finished product whiteness, good penetrability after processing; And can both be suitable for all kinds of slurries.But use the method to have destarch rate problem on the low side, only can reach 50% ~ 70%.

The singe fabric processed of the process that the present invention will obtain places to move back and boils rinsing combination machine and carry out destarch and process, and move back the running parameter that boils rinsing combination machine and arrange as follows: the speed of a motor vehicle is 60 ± 2m/min, and the time of banking up is 40min, and the crawler belt temperature is 99 ± 1 ℃.Hot water circuit with 93 ± 3 ℃ in the 1st ~ 2 lattice rinsing bowl is washed, in the 3rd lattice rinsing bowl, be that 80 ± 5 ℃ of hot water carry out circulating water wash with water temperature, in the 4th ~ 7 lattice rinsing bowl, with 93 ± 3 ℃ hot water wash, in the 8th lattice rinsing bowl, wash with 80 ± 5 ℃ hot water circuit.Destarch working solution temperature is 80 ± 5 ℃ in the hopper, the destarch working solution comprises the efficient destarch enzyme JN-160 of the component of following mass concentration: 3g/L and the bleeding agent CG of 3g/L, 1# ~ 2#, 4# ~ 7# roll applied pressure is 0.24 ± 0.02Mpa, the 3# nip pressure is 0.2 ± 0.02Mpa, high-capacity squeezer pressure is 3.5bar, water drain valve pressure 0.4 ± 0.1MPa, each rinsing bowl and drying cylinder tension rack pressure are 0.2 ± 0.1Mpa, cropping clot pressure is 0.5 ± 0.1Mpa; No. 2 groove adds the flow-control of water spinner flowmeter at 0.6 ± 0.1m
3/ h; No. 8 groove adds the flow-control of water spinner flowmeter at 0.9 ± 0.1m
3/ h, steam box scale window liquid level and pipe bent position keep level, finish the destarch of fabric is processed.
Compare by the result with embodiment 6, the result shows, the destarch rate of the fabric that method provided by the invention obtains has improved approximately 25%, and its mechanical property also is improved, this illustrates that method provided by the invention carries out destarch to fabric, destarch rate and the mechanical strength of fabric be can improve, the carrying out of follow-up dyeing and finishing technology and the dyeing and finishing level of raising fabric are conducive to.
As seen from the above embodiment, the invention provides a kind of desizing method of fabric, may further comprise the steps: a) pending fabric is carried out Cement Composite Treated by Plasma; B) fabric that described step a) is obtained carries out destarch to be processed.Before the present invention carries out destarch with pending fabric, it is carried out Cement Composite Treated by Plasma, high energy particle produces corrasion to the textile fabric surface in the plasma, make the continuous covering state of fiber spreading mass and wax oxidized and destroy, the strand of slurry is cut off, serosa surface forms hole and crack, is conducive to caustic soda and infiltrates; Plasma is introduced the hydrophilic radicals such as hydroxyl, carboxyl simultaneously, and the caustic soda Fast-swelling decomposes slurry, and the slurry solubility is improved, and contains the more wax of c h bond also oxidized, and the C=O linkage content is increased, and impurity is easy to be removed; Cement Composite Treated by Plasma can also be carried out chemical modification to fiber surface: can generate ion and free group at fiber surface, the crystal region of the large molecular surface of fiber and the ratio of amorphous region are changed, thereby change water imbibition and the permeability of fiber surface.Because of above-mentioned reason, when containing caustic soda in the destarch working solution that adopts, lower NaOH consumption just can make the water imbibition of COTTON FABRIC obtain larger raising, is conducive to fabric and realizes cleaning destarch.Experimental result shows, desizing method provided by the invention can reach more than 85% the destarch rate of fabric, has guaranteed the quality of fabric in follow-up printing and dyeing, and has improved the feel of fabric, has improved level in kind.
The above only is preferred embodiment of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
