Knitted fabric heat treatment device

Abstract

The invention discloses a knitted fabric heat treatment device which comprises a stacking box provided with a fabric feeding port and a fabric discharging port. A knitted fabric is fed into a cavity of the stacking box through the fabric feeding port, colored in the cavity and then discharged out through the fabric discharging port. The fabric feeding port is provided with a fabric feeding driving roller, a fabric feeding driven roller and a front-portion power device, a fabric swinging device is arranged at the lower end, and two sides of the fabric swinging device are provided with spraying pipes which are provided with multiple spraying holes. When the knitted fabric is dragged by the fabric feeding driving roller and swung by the fabric swinging device, the knitted fabric is sprayed through the spraying holes of the spraying pipes. The fabric discharging port is provided with a fabric discharging driving roller, a fabric discharging driven roller and a rear-portion power device, and an inflating pipe is arranged at the lower end and provided with multiple blowing holes towards the knitted fabric moving direction. When the colored knitted fabric moves, the inflating pipe blows air to enable the knitted fabric to be inflated and expanded, and the knitted fabric indentation can be prevented. A steam pipe is arranged outside the stacking box and extends below the liquid level of washing coloring liquid in the stacking box.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing, in particular to a heat treatment device for knitted fabrics. Background technique [0002] In the field of textile printing and dyeing technology, knitted fabrics often need to be colored after cold stacking. The purpose is to make knitted fabrics dyed and printed fabrics to complete the moisture absorption and temperature rise of fibers and colorants, and to promote the transfer of dyes in colorants to fibers. , the coloring treatment should complete the chemical reaction of the dye, the dyeing, diffusion and fixation of the dye to the fabric. At present, the steaming method or direct hot water washing method is usually used in the industry, but the disadvantages of the steaming method are that the amount of steam is large, the equipment cost is large, and the investment is large. It is difficult to control the steaming temperature and humidity during the steaming process. ...
