    FabricDyeing And FinishingTextiles

    1. minimize tension in the process of refining and bleaching.


    2. in dyeing and finishing In the process of drying, all wet cloth drying is to stretch the tension as much as possible, reduce elongation and avoid excessive narrowing of the door width. If the machine is open width and even after drying, add a small cloth box after opening, and then insert into the rack to avoid excessive tension between the open width and the rolling water.


    3. in the mercerizing process, we should grasp the expansion tension to maintain the width of the fabric and pay attention to controlling the weft tension.


    4. leveling machine guide bar in each process. The rod and barrel should be strengthened to ensure smooth and smooth finish. When the tension is relaxed, the guide rollers in the wrinkled flume should be operated freely. The line speed difference between the front and rear rolls of the same machine should not be too large. According to the tension, the cloth should not be masked. In the segmented process of the long stage, there should be elastic adjustment, opening and lowering device or sectional transmission adjustment device to control the tension.


    5. the mercerizing products should strictly control the tension in the process of the following process. Since the mercerizing shrinkage rate is increased again after the mercerizing, the width of the semi products can be worked out in each process, and the cloth should be checked in the various machines. After that, the process should be checked and accepted to ensure the width of the semi finished products.


    6. for some mechanical movement tension, manual control of tension is needed. Strict technological operation, strengthening technological operation, strengthening mechanical cleaning, reducing running tension and effectively reducing shrinkage of fabrics.


    7. to strengthen the inspection of mercerizing process conditions, conditional dyeing mills can use straight roller and cloth with mercerizing.


    8. the varieties with larger shrinkage rate should be pre shrinking and reducing shrinkage, such as khaki and wartada poplin fabric. In these varieties in tight processing. According to mechanical relaxation of tension, the best shrinkage rate is also about 4%. This shrinkage should be further reduced by pre shrinking method. After shrinkage treatment, the shrinkage rate of products is reduced. At the same time, you can get a better handle, clear texture and soft luster.


    9. for larger varieties of weft shrinkage, due to the unreasonable width of the fabric, even if the reasonable processing conditions, there is still a larger shrinkage rate of the latitudinal shrinkage. The further improvement measures must be taken. In addition, it is necessary to improve the specification of the grey cloth, and widen the width of the fabric without increasing the cost or increasing the cost, so as to ensure the reduction of the weft shrinkage to the required range.


    10. for the polyester cotton blended fabric, we must do a good job in the process and operation of the qualitative mercerizing process, so we can control the shrinkage rate better.
