Description

A device for pretreating fabrics in cylinders

technical field

The utility model relates to a device for dyeing and pretreating fabric in a vat with steam in a printing and dyeing factory, in particular to the device used on a cloth dyeing machine, which belongs to the technical field of the textile industry.

Background technique

A general dyeing machine includes structures such as a nozzle and a cloth storage tank, so that the fabric circulates in the dyeing machine in a continuous rope-like manner. After the fabric passes through the dyeing nozzle, it enters the distribution device and then enters the fabric storage bin. However, due to the weaving and material of different fabrics, when the dyeing machine is running circularly, some creases are tightly stuck and fixed without opening the conversion position, so that the fixed folded state continues for multiple cycles in the cylinder, resulting in failure after dyeing. Clear crease marks. In the past, although some dyeing users in printing and dyeing factories would use air-flow dyeing machines, the air nozzles were added to blow the fabric fluffy, reducing the chance of creases, thereby increasing the permeability of the dyeing liquid, so as to reduce the occurrence of the above-mentioned problems. However, the cost of air-flow dyeing equipment is relatively high, and the operation is relatively power-hungry, which deters some dyeing liquor factories.

However, there are some hidden dangers in the above-mentioned system. After adding the air nozzle, although the uneven dyeing has been reduced, it still occurs from time to time. If a certain type of fabric is heavy, it is difficult to blow the fabric, resulting in the fabric often not being fully fluffy and blown open, causing repeated folding positions. It can solve the problem of uneven dyeing due to creases. In order to solve this problem, we can only prolong the dyeing time, increase the force of the blower fan and the force of the water pump, so as to strengthen the flow and pressure of the dyeing liquor, blow the fabric completely and speed up the running speed. However, this will not only lead to an increase in energy consumption, but also may damage the surface of the fabric fibers, resulting in poor dyeing of the fabric, which is not worth the loss for the user. Another solution is to use a pre-treatment machine before dyeing to heat the fabric to soften it, so as to speed up the running of the fabric and reduce uneven dyeing. However, this lack of automation involves manually moving the fabric to the pre-processing machine. The time required will result in a high cost of professional labor, thereby wasting a lot of manpower and time, increasing energy consumption, and reducing production efficiency and economic benefits. In order to further improve the above technology, the utility model is proposed.
