Problems solved by technology

The shrinkage rate of the cotton cloth after shrinkage is below 5%, but because the moisture content in the wet cloth is still about 50% after washing and dehydration, it takes 50-60 minutes to dry in the ring dryer. Longer, the cloth surface is prone to pilling

Embodiment Construction

[0012] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0013] see figure 1 , the embodiment of the present invention includes:

[0014] A method for improving shrinkage by spray ring drying, comprising:

[0015] Enter the semi-finished cloth after dyeing and setting into the spray humidifier for spray humidification. The machine speed of the spray humidifier is 15-20 m / min, preferably 20 m / min, and the moisture content of the semi-finished cloth is kept at about 20%; then the humidified The final semi-finished cloth enters the ring dryer for drying. The temperature of the ring dryer is 75-90°C, preferably 80°C, and the drying time is about 20 minutes.

[0016] The invention discloses a method for ...

Abstract

The invention discloses a method for improving shrinkage through spraying loop drying. The method comprises the following steps: sending a piece of dyed and shaped semi-finished cloth into a spraying humidifier to perform spraying and humidification, wherein the machine speed of the spraying humidifier is 15-20m / min; and sending the humidified semi-finished cloth in a loop drying cylinder to perform loop drying at 75-90 DEG C, wherein the water content of the humidified semi-finished cloth is about 20%. In the method for improving the shrinkage through spraying loop drying, after the semi-finished cloth is sprayed in the spraying humidifier, the semi-finished cloth is dried in the loop drying cylinder, thus the shrinkage of a fabric can be improved, the pre-shrinking time can be greatly saved and the pilling phenomenon of the cloth can be improved.

Description

technical field [0001] The invention relates to the field of fabric treatment, in particular to a method for improving shrinkage by spray ring drying. Background technique [0002] During the weaving and dyeing and finishing process of the fabric, the fiber has to be stretched many times, the processing time is long, the warp direction is under tension, and the buckling wave height in the warp direction is reduced, so elongation will appear. When the hydrophilic fiber fabric is soaked in water, the fiber will swell, and the diameter of the warp and weft yarns will increase, so that the buckling wave height of the warp yarn will increase, and the length of the fabric will shorten, forming shrinkage. The percentage of the shortened length to the original length is called the shrinkage rate. The traditional way to improve shrinkage is to wash the fabric in a vat first, then dehydrate and then ring dry. After the fabric is washed with water, it is slowly dried in a relaxed sta...
