In the scouring machine 1, the scouring machine has an impeller drum structure, and the scouring machine impeller 103 operates intermittently, that is, the impeller drum rotates at a certain angle (the angle between two adjacent blades) at regular intervals, and the interval The time can be adjusted according to the specifications of the processed fabric.

Referring to shown in Fig. 4, a kind of bleaching process of the utility model according to the above-mentioned continuous rolling bleaching process bleaching machine comprises the following steps:

S1, into the cloth;

S2. The fabric 10 enters the slack anti-folding refining machine 1 for refining, which is used to remove natural impurities, contaminants and weaving slurry on the fabric 10;

S3, the fabric 10 is washed with water for the first time to remove the refining agent on the fabric 10;

S4, the fabric 10 enters the padding machine 3 for scouring and bleaching processing;

S5, the fabric 10 enters the first steam box 4 for the first steaming;

S6, the fabric 10 enters the second steam box 5 for steaming for the second time;

S7, the fabric 10 is washed with water for the second time to remove the scouring and bleaching liquid attached to the surface of the fabric 10;

S8, the fabric 10 enters the acid neutralizer 7, dipped in the acid neutralizing solution for neutralizing and removing the alkaline substances remaining on the fabric 10;

S9, the fabric 10 enters the stacking tank 8 to be stacked for prolonging the acid neutralization time;

S10, washing the fabric 10 for the third time, for cleaning the acid neutralizing solution attached to the surface of the fabric 13;

S11, drop cloth.

Preferably, penetrant and complexing agent are added to the relaxation and anti-folding scourer 1 in step S2, the temperature in the relaxation and anti-folding scourer 1 is 50-80° C., and the treatment time of the fabric 10 is 8-12 minutes. Add caustic soda, hydrogen peroxide, scouring agent and stabilizer to the padding machine 3 in step S4. In step S5, the temperature in the first steamer 4 is 70-85°C, and the treatment time of the fabric 10 is 25-35 minutes; the temperature in the second steamer 5 in step S6 is 90-100°C, and the treatment time of the fabric 10 is 25 minutes. ~35 minutes. In step S7, water washing is performed three times, and the temperatures of the three water washings are 70-80°C, 40-50°C, and 15-30°C in sequence. While the concentration of the scouring and bleaching solution on the surface of the fabric is reduced, the temperature of the washing is also reduced, and the surface of the fabric is cleaned more cleanly.

The fabric 10 moves slowly in the aqueous solution containing wetting agent, complexing agent, etc. under the intermittent operation of the drum of the scourer blade 103 . This process serves two purposes:

First, remove the mineral matter and some other impurities in the fabric 10 to prevent fiber damage caused by the catalytic action of the mineral matter on the decomposition of hydrogen peroxide;

Second, through the water swelling of the fiber, the fabric 10 is evenly shrunk and dense, which can not only obtain the best flat cloth surface effect, but also improve the ability of the fabric to resist extrusion and stretching in subsequent processing, without Creases due to extrusion.

After the cotton-type fabric is demineralized by the slack anti-folding scouring machine 1, it is washed by the unit washing machine and can be directly entered into the padding machine 3 for padding, scouring, bleaching, and bleaching. Chemical fiber fabrics) can be dropped here after washing.

The padding machine 3 for padding, scouring and bleaching liquid is also of the impeller drum type structure. In addition to "multi-dipping and multi-rolling", it can also be used for tubular open-width padding of tubular fabrics, and can be used for The so-called "versatile" padding of ropes, whether tubular or open-width fabrics.

The scouring and bleaching process in the padding machine 3 adopts the "alkali-oxygen one-bath one-step scouring and bleaching process", that is, the one-step scouring and bleaching process of caustic soda scouring and hydrogen peroxide bleaching in the same bath, and the key scouring and bleaching reaction process adopts the "stage thermal insulation steaming process". That is, the steaming process is divided into two temperature areas or multiple temperature areas for steaming, first low-temperature steaming and then high-temperature steaming. In this embodiment, two steaming boxes that can individually control the temperature are set, the steaming temperature of the first steaming box 4 is 70-85° C., and the steaming temperature of the second steaming box 5 is 90-100° C. ℃, which can effectively control the direction and speed of the hydrogen peroxide decomposition reaction, which can not only ensure the fabric to obtain excellent whiteness and "hair effect", but also minimize the damage to the fiber.

The steam box can be in the form of J-shaped box, crawler type, flap type, etc.; two independent steam boxes can be used in combination, or two steam boxes that can control the temperature independently can be set in the same steam box. Area.

The washing machine after scouring and bleaching is a continuous all-loose washing machine, which is composed of a plurality of second unit washing machines 6, and the water supply adopts the "countercurrent water supply" method; the unit washing machine has an impeller drum structure, and the fabric 10 In the fully loose state, it moves countercurrently under the carrying of the blade drum; the motion of the blade drum is intermittent rotation, and each time the rotation starts and stops, it can stir the movement of the fabric and the flow of water, and can intensify the gap between the fabric and the water. The impact movement between them to improve the washing efficiency.

In the middle of the continuous washing machine, an acid neutralizer 7 for acid neutralization and a stacking pool 8 for prolonging the acid neutralization time are specially set up, so as to completely remove the alkaline substances remaining in the fabric, especially the cotton fiber adsorption. of caustic soda.

The above is only a specific embodiment of the utility model, but the scope of protection of the utility model is not limited thereto, and any change or replacement that is not thought of through creative work should be covered within the scope of protection of the utility model .
