Description

Apparatus and method for pretreating fabric in cylinder

The invention relates to a device and a method for dyeing a fabric in a cylinder with a steam in a printing and dyeing factory, in particular to a device applied to a dyeing machine, and belongs to the technical field of the textile industry.

The general dyeing machine includes a nozzle and a storage tank, and the like, so that the fabric travels in a loop-like manner in the dyeing machine. After the fabric passes through the dyeing nozzle, it enters the swinging device and enters the storage cloth. However, in terms of different fabric weaving and material problems, part of the crease position is tightly fixed at the time of loop running in the dyeing machine without opening the switching position, so that the fixed folding state continues to perform multiple loops in the cylinder, resulting in dyeing. Fold marks that cannot be removed afterwards. In the past, some dyeing users used airflow dyeing machines, and the air nozzles fluffed the fabric to reduce the chance of creases, thereby increasing the permeability of the dye solution to reduce the above problems. However, airflow dyeing equipment is costly and consumes more electricity, which makes some dyeing plants deterred.

However, the above system has some hidden dangers. After adding the air nozzle, although the uneven dyeing has been reduced, it still appears. If a certain type of fabric is heavier, it is difficult to blow the fabric, and the fabric is often not fully fluffed, so that the folding position is repeated. Failure to solve the problem of uneven dyeing due to creases. In order to solve this problem, only the dyeing time can be prolonged, and the pushing force of the fan and the pump power can be increased to strengthen the flow and pressure of the dyeing liquid, completely blowing the fabric and speeding up the running speed. However, this will not only lead to an increase in energy consumption, but also an opportunity to damage the surface of the fabric fibers, resulting in poor dyeing of the fabric, which will not cost the user. Another solution is to use a pre-treatment machine before dyeing to heat the fabric to soften the fabric to speed up the fabric and reduce uneven dyeing. However, the lack of automation involves moving the fabric to the pre-treatment machine by hand. The time required will cause high labor costs, which will waste a lot of manpower and time, increase energy consumption, and reduce production efficiency and economic benefits. In order to further improve the above technology, the present invention is filed.
