Beam dyeing and rolling process

Abstract

The invention discloses a beam dyeing and rolling process, and belongs to the technical field of beam dyeing processes. The main principle of beam dyeing is as follows: cloth is wound on a mesh cylinder to form a cloth roll, the rolled cloth roll sprays out dye liquor from the mesh cylinder in the center of the cloth roll, and the cloth roll is dyed from the inner layer to the outer layer. Balance between friction increasing and overlarge density avoiding is the key point of exploration of cloth dyeing and rolling all the time. According to the process, 6-10 kg of counter weight is additionally arranged on a tension shaft of a beam rolling machine, and 1-2 kg of counter weight is sequentially reduced at the rolling position of 15-25 m and the follow-up rolling position every 12-17 m till the additional counter weight is 0. The internal and external densities of beam dyeing and rolling are controlled in a mode of gradually decreasing quantitative tension, so that the internal and external densities are balanced, the speed of dye liquor penetrating through cloth is uniform, no relative slippage exists between cloth covers, the dyeing quality is more uniform, and the yield is higher.

Description

technical field [0001] A warp beam dyeing and rolling process belongs to the technical field of warp beam dyeing process. Background technique [0002] The warp beam dyeing machine is a new equipment developed in recent years. It is an essential dyeing machine for printing and dyeing factories. Due to its mechanical composition characteristics, it is mainly suitable for dyeing filament light and thin fabrics. In the post-processing with the length of the shaft head as the order unit, it can show its superiority in dyeing, with flexible dyeing batches, good crepe effect, and small color difference between left, middle and right. order mode. [0003] The main principle of warp beam dyeing is: the cloth is wound on the net tube to form a cloth roll, and the finished cloth roll sprays dye solution from the net tube in the center of the cloth roll to dye the cloth roll from the inner layer to the outer layer. [0004] However, the actual dyeing process of warp beam dyeing is pr...

Problems solved by technology

[0004] However, the actual dyeing process of warp beam dyeing is prone to defects such as mesh tube damage and white edges, and wood grains like pine tree rings will appear on the cloth surface, which seriously affects product quality and production progress.
