Description
Technical Field
The invention relates to the technical field of alkali deweighting machines, in particular to an alkali deweighting production line for continuous production of superfine fibers.
Background
The alkali deweighting process is mainly a process of treating terylene and chinlon fabrics in high temperature and strong alkali liquor, utilizes the alkali liquor to hydrolyze, corrode and fall off 'sea' components in the fabrics, promotes the relaxation of fiber fabric tissues, reduces the mass, reduces the fiber diameter, and forms pits on the surface, thereby leading the fabrics to have soft hand feeling, soft luster and enhanced drapability, improving the moisture absorption and perspiration properties and the dyeability of the fabrics, leading the fabrics to have the general style of silk, and achieving a production process leading the fabrics to have real silk feeling.

The original guide roller for treating the rope-shaped grey cloth is changed into the guide roller for treating the open-width unfolding state of the grey cloth, and the grey cloth is unfolded into and out of the cloth in the treatment process, so that the heat treatment is uniform in the alkali deweighting process, and the links of manual dehydration and open-width are omitted. However, the treatment solution is put into the alkali treatment unit at one time, and partial polyester hydrolysate is generated in the grey cloth and is dissolved in the treatment solution, so that the concentration of the treatment solution is changed, the treatment solution is consumed at a higher speed in a high-temperature environment, so that the concentration change speed of the treatment solution is quicker, the bath ratios of the treatment solution in the reaction of the grey cloth in different time periods are different to some extent, and the final product of the grey cloth has the result that the reduction is inconsistent in all parts, so that the hand feeling is different.
The prior art also discloses an open width alkali deweighting machine, which sequentially comprises a cloth feeding device, an alkali treatment unit, a heating unit, a steaming and washing unit and a cloth swinging device, wherein a tensioning device is arranged between the cloth feeding device and the alkali treatment unit, two rolling vehicles are respectively arranged between the alkali treatment unit and the heating unit, between the heating unit and the steaming and washing unit and between the steaming and washing unit and the cloth swinging device, and an oven is arranged between the cloth swinging device and the two rolling vehicles close to the cloth swinging device. The method comprises the steps of changing a dip dyeing mode into spraying, reducing alkali liquor stained on grey cloth, further reducing the alkali liquor quantity on the grey cloth by using a padder, heating the grey cloth by using a heating unit to promote hydrolysis reaction, enabling polyester hydrolysates not to be mixed into the alkali liquor to be sprayed, achieving the effect of ensuring consistency of the bath ratio of the grey cloth, treating moisture and polyester hydrolysates on the grey cloth by using the padder, finally cleaning the grey cloth by using a steaming and washing unit, extruding residual liquid on the grey cloth by using the padder, drying the grey cloth by using an oven, and finally collecting the grey cloth by using a cloth swinging mechanism; according to the specification of grey cloth, the spraying amount of alkali liquor can be controlled, polyester hydrolysate is prevented from entering the alkali liquor, so that the bath ratio of the grey cloth is kept unchanged, the alkali liquor is prevented from being heated and lost, and the effect of reducing the cost is achieved. However, due to the factors of less amount of alkali liquor sprayed, shorter decrement time and the like, phenomena of insufficient decrement or incomplete decrement and the like are necessarily caused, and particularly, the purpose of decrement cannot be achieved or can not be achieved completely for thicker and denser grey cloth.
Meanwhile, on one hand, the existing alkali deweighting equipment can not realize continuous deweighting production of large-batch grey cloth, so that quality batch difference is caused; or quality defects, such as folds, water spots and the like, which cannot be eliminated, are formed due to the multi-layer folding of the grey fabric.
