Technical Field

The invention relates to the technical field of alkali deweighting machines, in particular to an alkali deweighting production line for continuously producing superfine fibers.

Background

The alkali deweighting process is mostly a process of treating terylene and chinlon fabrics in high-temperature and strong alkali liquor, utilizes the hydrolysis, corrosion and falling off of sea components in the fabrics by the alkali liquor to promote the relaxation of fiber fabric tissues, reduce the quality, reduce the fiber diameter and form pits on the surface, thereby ensuring that the fabrics have soft hand feeling, soft luster and enhanced drapability, not only improving the moisture absorption and sweat releasing performance and the dyeability of the fabrics, but also ensuring that the fabrics have the common style of silk and achieving the production process that the fabrics have real silk feeling.

The prior art discloses an open-width alkali deweighting machine, which comprises a machine box body, a cloth feeding device, a cloth discharging device, a treatment solution and a treatment solution heater, wherein the improvement is that the cloth feeding device and the cloth discharging device are composed of guide rollers for adjusting the running speed of flat gray cloth; the device comprises a machine box body, a pressing-down conveying crawler and a gray fabric conveying crawler, wherein the machine box body is internally provided with the pressing-down conveying crawler and the gray fabric conveying crawler which are matched up and down, the pressing-down conveying crawler and the gray fabric conveying crawler are formed by a crawler and a driving shaft for driving the crawler to rotate, the crawler at the lower part of the pressing-down conveying crawler is arranged below the liquid level of a treatment solution in a machine box, the treatment solution refers to the treatment solution which is heated to 98-00 ℃ by a treatment solution heater under normal pressure in a treatment process, the surfaces of the pressing-down conveying crawler and/or the crawler of the gray fabric conveying crawler are distributed and provided with prismatic protrusions. The original guide roller for treating the rope-shaped gray fabric is changed into the guide roller for treating the open-width unfolded state of the gray fabric, and the gray fabric is unfolded, fed and discharged in the treatment process, so that the heat treatment is uniform in the alkali decrement process, and the links of manual dehydration and open-width are saved. However, the treatment solution is added at one time, the grey cloth generates partial terylene hydrolysate in the alkali treatment unit and is dissolved in the treatment solution, so that the concentration of the treatment solution is changed, the consumption speed of the treatment solution in a high-temperature environment is high, the concentration change speed of the treatment solution is quicker, the bath ratio of the treatment solution in reaction of different time periods of the grey cloth is different, and the final product of the grey cloth has the result of different hand feelings due to inconsistent decrement at each part.

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, an evaporation washing unit and a cloth swinging device, wherein a tensioning device is arranged between the cloth feeding device and the alkali treatment unit, two roller padders are arranged between the alkali treatment unit and the heating unit, between the heating unit and the evaporation washing unit, between the evaporation washing unit and the cloth swinging device, and an oven is arranged between the cloth swinging device and the two roller padders close to the cloth swinging device. The method changes a dip dyeing mode into spraying, reduces alkali liquor stained on the grey cloth, further reduces the amount of the alkali liquor on the grey cloth by using a padder, then heats the grey cloth by using a heating unit to promote hydrolysis reaction, so that terylene hydrolysate cannot be mixed into the alkali liquor to be sprayed, the effect of ensuring the consistency of the bath ratio of the grey cloth is achieved, water and the terylene hydrolysate on the grey cloth are treated by using the padder, the grey cloth is finally cleaned by using a steaming and washing unit, residual liquid on the grey cloth is extruded by using the padder, then the grey cloth is dried by using an oven, and finally the grey cloth is collected by using a cloth swinging mechanism; according to the specification of grey cloth, the spraying amount of the alkali liquor can be controlled, and polyester hydrolysate is prevented from entering the alkali liquor, so that the bath ratio of the grey cloth is kept unchanged, the alkali liquor can be prevented from being heated and lost, and the effect of reducing the cost is achieved. However, due to the factors of less sprayed alkali liquor, shorter decrement time and the like, the phenomenon of insufficient or incomplete decrement and the like can be caused inevitably, and particularly, the aim of decrement cannot be achieved at all or can be achieved completely for thicker and denser gray fabric.

Meanwhile, on one hand, the existing alkali decrement equipment can not realize continuous decrement production of large-batch gray fabric, so that quality lot is poor; or quality defects such as crease, water spot and the like which cannot be eliminated are formed due to multi-layer folding of the grey cloth.
