Abstract

The present invention provides an apparatus and method for pre-treating a fabric in a vat. When a fabric is running in a fabric dyeing machine, a steam nozzle can be disposed behind a fabric guiding tube and in front of a fabric plaiter, to spray high-temperature steam to the fabric, such that a stress is released from the fabric, and the fabric can run more smoothly, thereby greatly reducing the possibility of fold repeat of the fabric. Meanwhile, the permeability of dyes is also improved, the dyeing is more even, a dyeing machine can have a better color yield, and the dyeing time is shortened; moreover, because the high-temperature steam has functions of drying and moisture absorption, an even dyeing effect can be achieved without heating the fabric by a user using a pre-treating machine, so that the purposes of energy saving, consumption reduction, low carbon emission and environmental protection can be achieved, thereby reducing costs.

Description

Apparatus and method for pretreating fabric in cylinder

Technical field

The invention relates to an apparatus 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.

Background technique

The general dyeing machine includes a nozzle and a storage tank, and the like, so that the fabric travels cyclically in the dyeing machine in a continuous loop shape. After the fabric passes through the dyeing nozzle, it enters the swinging device and enters the storage cloth. However, in the case of different fabric weaving and material problems, part of the crease position is tightly fixed and does not open the switching position during the circulation operation in the dyeing machine, so that the fixed folding state continues for a plurality of cycles in the cylinder, and the dyeing cannot be performed. Cleared color marks. 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, the airflow dyeing equipment is costly and operates at a lower level, 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. It can 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 application of the present invention is filed.
