A device for salt-free dyeing of unboiled and bleached cotton textiles with reactive dyes

Abstract

The invention discloses an apparatus to perform salt-free dyeing on non-scoured non-bleached cotton textiles by a reactive dye. The apparatus comprises a base; the upper surface of the base is provided with a mounting cavity; a bottom plate is connected inside the mounting cavity through a buffer mechanism; two support rods are fixedly mounted symmetrically on the upper surface of the bottom plate; a top plate is fixedly connected to the ends, far away from the bottom plate, of the two support rods; a dyeing tank is fixedly mounted at the center of the upper surface of the bottom plate; a mounting chamber is arranged in the dyeing tank; a driving motor is fixedly mounted at the inner bottom of the mounting chamber; a rotary shaft is fixedly connected to the output end of the driving motor;the upper end of the rotary shaft runs through the inner bottom of the dyeing tank and is fixedly sleeved with stirring blades. The apparatus allows a cotton textile to be dyed evenly in the dyeing tank so that the cotton textile is dyed better; both the top and back of the cotton textile can be dried by blowing; the dye that is drained can leak into the dyeing tank via a screen for the purpose of recycling.

Description

technical field [0001] The invention relates to the technical field of cotton textile processing, in particular to a device for salt-free dyeing of unboiled and bleached cotton textiles with reactive dyes. Background technique [0002] The spinning process of processing cotton fiber into cotton yarn and cotton thread. This process is also suitable for spinning cotton-type chemical fiber yarns, medium-length fiber yarns, and blended yarns of cotton and other fibers. Cotton fabric has good wearing performance, low price, and relatively simple cotton spinning process, so it occupies the leading position in the textile industry. The entry of cotton textiles into the consumer sector also requires an essential dyeing process, so that future clothing can have bright and bright colors. [0003] But there are following defects in the existing cotton textile dyeing process: the long-term accumulation of dye in the dyeing pool may cause the dye to deposit on the inner bottom of the d...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the shortcomings in the prior art, such as: the long-term accumulation of dye in the dyeing tank may cause the dye to deposit on the inner bottom of the dyeing tank and affect the dyeing effect of cotton textiles, making the dyeing uneven; Most of the cotton textiles are dried by a blower, but the cotton textiles are not easy to turn over, which makes the back of the cotton textiles difficult to be blown dry, which will affect the coloring speed of the cotton textiles; when the cotton textiles are rinsed in the dyeing tank, the dyeing tank will shake. Affecting the placement stability of the dyeing device, a device for salt-free dyeing of unboiled and bleached cotton textiles with reactive dyes is proposed
