Problems solved by technology

[0022] The traditional process requires two processes of enzyme wool and deactivation before the dyeing of nylon cotton fabrics, which has disadvantages in production: 1. There are many production processes and low production efficiency; 2. The energy consumption of water, electricity and steam is large; 3. , Enzyme wool and inactivation processes need to use a lot of clean water for cleaning, the consumption of clean water is high, and the discharge of sewage is large

Abstract

The invention relates to a one-bath dyeing process, in particular to a one-bath process for hair removal and reactive dye dyeing of brocade / cotton fabrics. Follow the steps below: select sample cloth → gray cloth desizing → gray cloth pre-setting → gray cloth mercerizing → dyeing formula design → sample vat dyeing → drying and setting → oiling and setting → pre-shrinking finishing → finished product inspection. A one-bath process of hair removal and reactive dye dyeing of nylon / cotton fabrics, which has obvious energy-saving and emission-reduction effects, and the hand-feel elasticity, color fullness, and various quality internal indicators of the processed fabrics can meet the requirements of different customers.

Description

technical field [0001] The invention relates to a one-bath dyeing process, in particular to a one-bath process for hair removal and reactive dye dyeing of brocade / cotton fabrics. Background technique [0002] Nylon / cotton fabric has cotton fibers in the weft direction, so there are cotton fiber fluffs on the surface of the gray fabric. The finished product requires the surface of the gray cloth to be smooth and clean, so the fluff of the cotton fiber must be removed. Nylon cotton fabric is not suitable for high temperature singeing of singeing machine, high temperature will damage nylon fiber. The general traditional process to remove the fluff of cotton fiber in Nylon cotton fabric is to carry out enzyme wool treatment with biological enzyme auxiliary agent before dyeing. [0003] Traditional process: Enzyme wool → inactivation → reactive dye dyeing (dyeing cotton fiber) [0004] 1. The production process and corresponding production parameters of biological enzyme auxil...
