Rope-shaped cloth cooking pot: high-temperature cooking

All kinds of cotton fabrics, especially fabrics with tight texture and high scouring requirements, such as poplin, satin, etc., and fabrics with particularly thin texture, such as gauze, voile, etc.
1. It has a good effect on removing impurities from cotton fibers and removing cotton seed husks, but the uniformity is slightly poor.

2. Gray fabrics with different textures can be boiled together in a pot.

3. It is intermittent processing with low efficiency, high labor intensity and slow turnover.

4. Dyeing of heavy fabrics is prone to defects such as scratches, wrinkles, and localized opacity.

5. The fabric stretches little.

Rope-shaped continuous: steam cooking

Suitable for all kinds of pure cotton fabrics below 250g/square meter
1. Continuous production has low labor intensity and fast product turnover.

2. The impurity removal effect is good and the quality is uniform.

3. It is prone to weft skew, scratches, holes, white spots and pressure marks, and is not suitable for dyeing thick and heavy fabrics.

4. The steaming box should use saturated steam to avoid yellow spots and holes.

Loose rope: continuous steam cooking

Continuous with the general rope shape

Steam cooking

1. Continuous production, extremely fast speed, high efficiency in various cooking methods, low labor intensity, and fast product turnover.

2. The impurity removal effect is good, the quality of semi-finished products is uniform, and the weft skew is smaller than that of ordinary rope steaming.

3. Because the loose elongation is smaller, the weft inclination is also smaller.

4. Not suitable for pre-treatment of heavy fabrics.

5. If the steam in the steamer is not used properly, it will easily cause holes. Saturated steam should be used.

Open width high temperature and high pressure dye vat scouring

Suitable for processing cotton and cotton blended fabrics, especially heavy fabrics, such as polyester-cotton khaki, etc.

1. The impurity removal effect is good and the quality of semi-finished products is uniform.

2. It is intermittent processing with low efficiency, high labor intensity and slow turnover.

3. Does not produce scratches or pressure marks, and is suitable for heavy fabrics.

4. The fabric has long elongation and no weft bias.

Open-width rolling: steam cooking

Suitable for all types of cotton fabrics, especially heavy fabrics, such as yarn cards, thread cards, etc.

1. The equipment is simple, requires less investment than continuous cooking, and can be started quickly.

2. The variety has strong adaptability and no abrasions or pressure wrinkles.

3. It is semi-intermittent processing and has high labor intensity.

4. The cooking effect inside the roll is better than that outside the roll (because it is rolled up first and then rolled back), and the cooking effect before and after is slightly different.

Open width continuous: steam cooking

Widely applicable to all kinds of fabrics, especially polyester-cotton blended thin fabrics

1. Continuous production, low labor intensity, fast turnover and easy operation.

2. There are many types of equipment, including L boxes, R boxes, flip boxes, and stacking boxes.

3. In addition to stacking boxes, other equipment processing thick fabrics is prone to horizontal wrinkles and uneven raw and cooked rungs.

4. The steaming and turning equipment for stacked rolls is complex, prone to wrinkles, the length of the cloth roll will gradually decrease, and the operation control requirements are high.

5. The impurity removal effect is good and the quality is relatively uniform.

6. There must be more than 10cm of working fluid at the steaming bottom of the crawler box to keep the fabric in a wet steaming state, otherwise it is easy to produce horizontal rungs and uneven dyeing.

Open width high temperature and high pressure: continuous steam cooking

Suitable for pure cotton, especially heavy fabrics
1. It can be produced continuously and has low labor intensity.

2. The impurity removal effect is good and the quality of semi-finished products is uniform.

3. The import and export sealing requirements are high, and polytetrafluoroethylene is generally used. It has a long service life and the seal is prone to air leakage, so it needs to be replaced regularly.

4. The steaming time is short, a lot of materials are used, the cost is high, the equipment maintenance is difficult, and polyester and cotton fabrics are not suitable for processing.

Underwater track
Suitable for all types of fabrics, especially heavy fabrics
1. High continuous production efficiency.

2. It penetrates evenly and the cooking cloth is of good quality.

3. Loosely immersed and floating in the refining liquid, no creases or scratches.

4. A lot of materials are used, and the residual liquid in the box must be equipped with a recovery device.
