Example Embodiment

[0021] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention will be further explained below in conjunction with specific embodiments.

[0022] The dyeing process of nylon fabric provided by the present invention includes the following steps:

[0023] (1) First, cold pile the fabric, put the fabric into a flat tank, and put 50g / L alkali in the flat tank, the alkali is one or two of sodium hydroxide and potassium hydroxide, and put 2g / L of penetrant, cold reactor time is 12h;

[0024] (2) Then carry out desizing treatment, pass steam into the flat cylinder to make the temperature in the flat cylinder reach 45℃; when the temperature in the flat cylinder reaches 45℃, keep it warm, then add the desizing refining agent for the first desizing For pulp refining treatment, the bath ratio of the first desizing refining is 1:20, and the time is controlled at 4 hours; in the first desizing refining tr...

Abstract

The invention discloses a nylon fabric dyeing process which comprises the following steps: (1) performing cold pad-batch treatment on a fabric; (2) performing desizing treatment; (3) performing cold impregnation; (4) feeding the fabric subjected to cold impregnation into a dyeing machine, and dyeing; (5) fixing the dyed fabric, wherein the initial temperature is 30-40 DEG C, the fixing temperature is 80 DEG C, the fixing time is 20-25 minutes, a fixing agent is A-12 and NS-1, and the concentration of the fixing agent is 2-4g/L; and (6) finally setting, wherein the setting temperature is 145-155 DEG C, and the setting time is 0.5-1 minute. According to the invention, a fabric can be directly put in a dye vat and dyed, the fabric can not be creased or scratched in the dyeing process so as to avoid crease marks, the traditional wrapping method does not need to be used, and the production efficiency is greatly improved; and the fabric has better dyeing effect, and the dye has better permeability in the fabric. Thus, the finished product has less color difference, thereby omitting the reworking and shading step, saving manpower and material resources and improving the quality of the finished product.

Description

technical field [0001] The invention relates to a printing and dyeing process, in particular to a nylon fabric dyeing process. Background technique [0002] Nylon fabric was developed by Carothers, an outstanding scientist in the United States, and a scientific research team under his leadership. It is the first synthetic fiber to appear in the world. The emergence of nylon has brought a new look to textiles. Its synthesis is a major breakthrough in the synthetic fiber industry and an important milestone in polymer chemistry. [0003] Nylon is the trade name of polyamide fiber, also known as nylon (Nylon). The English name Polyamide (referred to as PA), its basic composition is an aliphatic polyamide linked by amide bonds—[NHCO]—. [0004] When dyeing nylon fabric, due to the poor permeability of this fabric, the usual dyeing auxiliaries process will cause the dyeing effect of the fabric to be unsatisfactory, and the dye cannot enter the interior of the fabric. Not only th...
