The soaking and rolling tank is provided with an interlayer which can be filled with cold water to cool the alkali liquor in the tank. A communicating pipe is arranged between the two leaching tanks so as to facilitate the flow of alkali liquor.
The pressure of the first soaking and rolling groove is smaller, and the first soaking and rolling groove can be pressurized by a lever, so that the fabric is provided with more alkali liquor, and the action of the alkali liquor and the cellulose is facilitated.

In order to prolong the alkali carrying time of the fabric, meet the requirement of full penetration and reaction of alkali to the fabric and simultaneously prevent the fabric from shrinking after swelling, more than ten iron hollow cloth stretching rollers which are alternately arranged up and down are arranged above the frame between the two padding tanks, and the diameter is 460-500 mm. Generally, the operation is passive, and the operation is active.
To prevent the fabric from shrinking, the wrap angle surface of the fabric along the cloth stretching roller should be larger, and the linear speed of the back groove should be larger than that of the front groove. Thus, the warp direction of the fabric has certain tension to prevent shrinkage; and the weft direction utilizes the friction resistance to prevent shrinkage.

And the weak alkali solution sucked by the pipette is sequentially discharged into each weak alkali tank below the machine, and then the weak alkali solution in the weak alkali tank and the weak alkali solution from the dealkalizing steam box are respectively conveyed to the leaching device by each pump according to the principle of gradual countercurrent leaching.
And finally, in order to further wash off the caustic soda on the fabric, after the fabric is subjected to tenter rinsing, the fabric enters an alkali removal box with high alkali washing efficiency, and the alkali removal box is only set to be 1 lattice. The alkali removing box is a stainless steel closed box, and a box cover can be hung so as to facilitate cloth penetration or fault treatment; the upper and lower parts in the box are respectively provided with an iron cloth guide roller row, the upper row is active, and the lower row is passive; water sealing ports are arranged at the inlet and the outlet to prevent steam in the box from escaping; the bottom of the box is filled with water to wash off alkali, the bottom of the box is inclined, so that the alkali liquor can flow backwards from the back of the box against the direction of the fabric, and a direct steam pipe is arranged between the fabric layers to spray steam to the fabric, so that part of the steam is condensed into water on the fabric and permeates into the fabric, thereby playing the roles of diluting the alkali liquor and raising the temperature.
