Problems solved by technology

The existing cold pad-batch dyeing machines do not consider the characteristics of knitted fabrics that are sensitive to tension and easy to curl, and the distance between each roller is relatively large. Most of them are only suitable for woven fabrics. Cold pad-batch dyeing machines for knitted fabrics need to be developed

Abstract

The invention provides a cold pad-batch dyeing machine for knitted fabric.The cold pad-batch dyeing machine is characterized by comprising an open-width cloth inlet unit, a dust suction unit, a cooling unit, an edge unfolding unit, a dyeing unit, a cloth outlet unit and a moving and rolling unit.The open-width cloth inlet unit is arranged on the upper side of the dust suction unit and the cooling unit.The dust suction unit is arranged on the left side of the cooling unit.The cooling unit, the edge unfolding unit, the dyeing unit, the cloth outlet unit and the moving and rolling unit are sequentially arranged from left to right.An open-width processing mode is adopted, the structure is compact, the knitted fabric is effectively prevented from being wrinkled or crimped in the processing process, tension changes are small in the deformation process of the knitted fabric, and the effect of even dyeing can be achieved.According to the cold pad-batch dyeing machine, low-tension control can be effectively carried out over the knitted fabric in the whole drying link; all the technological processes are short, the utilization rate of dyes can be greatly improved, water saving and consumption reducing are achieved, production cost is reduced, and environmental pollution is small.

Description

technical field [0001] The invention relates to a cold pad-batch dyeing machine, in particular to a cold pad-batch dyeing machine for knitted fabrics, belonging to the technical field of textile printing and dyeing machinery. Background technique [0002] Exhaust dyeing is mainly used for dyeing knitted fabrics. This method consumes a lot of water and energy, seriously pollutes the environment, and occupies a large area of ​​the machine. It is difficult to meet the current requirements of green, environmental protection and high-efficiency production. Cold pad-batch dyeing is a semi-continuous pad-dyeing process between exhaust dyeing and continuous pad-dyeing, without drying and steaming, which greatly saves water and energy consumption and improves the utilization rate of dyestuffs. The cold pad-batch dyeing machine has simple equipment, short process flow, and little environmental pollution. Applying the cold pad-batch dyeing technology to knitted fabrics can make the dye...
