Measures to reduce the shrinkage of fabric

1. in the process of refining and drifting as far as possible to reduce tension.
2., during the dyeing and finishing process, all wet cloth drying is to loose the tension as much as possible, reduce the elongation and avoid excessive narrowing of the door width. If the machine is open and even drying, add a small cloth box after opening, and then put it into the rack to avoid excessive tension between the open width and the rolling water.
3. in the process of mercerization, it is necessary to grasp the width of the widening to keep the width of the fabric and to control the zonal tension.
4. the guide cloth rod of the flat washing machine in each process. The stick and dryer should be strengthened to ensure smooth and smooth. To avoid tension relaxation of guide roll wrinkling in flume to operate freely, and the same machine roller cylinder line speed difference should not be too large to grasp the tension size cloth will not prevail in the long process of mopping the floor section in Taiwan should be adjustable open down or segmented transmission frame device to control the tension adjusting device.
5. mercerized products should be strictly controlled after processing in the process of tension after elongation after mercerizing because in the actual production operation in the procedure of making semi-finished product width index in the machine to the cloth in to measure the examination to the shrinkage rate, after the order to pre process inspection of semi-finished products should be guaranteed the width.
6. for some mechanical tension, it is necessary to control the tension manually. Strict process operation, strengthen process operation, strengthen mechanical cleaning to reduce the operation tension effectively reduce the shrinkage of the fabric.
7. to strengthen the processing conditions of mercerizing dyeing factory inspection, the conditions can be used straight roller and fabric with mercerized.
The rate of the larger varieties to shrink by 8.: khaki, poplin fabric gabardine to pre shrinking treatment and reduce shrinkage. These varieties are in tight processing. Only on the mechanical relaxation of tension, it is best to shrink rate as high as 4% or so, it should adopt the pre shrinking shrinkage to further reduce the products after pre shrinking treatment not only reduces the shrinkage rate. At the same time, you can also get a better sense of hand, the lines are clear and soft.
9. for weft shrinkage larger varieties, some of the fabric width not reasonable, even if the reasonable processing conditions, still has a larger zonal shrinkage processing conditions poor shrinkage is bigger, must take further measures, to ensure the fabric mercerizing varieties fall to meet the requirements. In addition, we need to improve the specification of the grey fabric, and widen the width of the fabric without increasing the cost or increasing the cost, so that the weft shrinkage rate can be reduced to the required range.
10. for polyester synthetic fiber blended fabric to grasp the technology and operation can better control the qualitative mercerizing process shrinkage.
