Embodiment Construction

[0016] In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with examples, which are only used to explain the present invention and do not constitute a limitation to the protection scope of the present invention.

[0017] The present embodiment provides a kind of processing method before cheese dyeing, comprises the following steps:

[0018] Step 1: Loosen the original yarn, chamfer the corners, and load it into the dyeing machine;

[0019] Step 2: Add NaOH, chelating agent, hydrogen peroxide, high-efficiency oxygen bleaching non-silicon stabilizer, cleaning agent and penetrating agent in the dyeing machine at room temperature. The penetrating agent is fatty alcohol polyoxyethylene ether;

[0020] Step 3: Perform bath rinsing at a temperature of 98°C for 60 minutes, then keep warm at 65°C for 20 minutes;

[0021] Step 4: Add alkaline agent to neutralize after rinsing, then discharge the rinsing wat...

Abstract

A purpose of the present invention is to provide a treatment method used before cheese dyeing. According to the treatment method, a medium boiling-medium bleaching process is used, and 2-4 g / L NaOH, 6-8 g / L hydrogen peroxide, 4-8 g / L high efficiency oxygen bleaching non-silicon stabilizer, a detergent and fatty alcohol polyoxyethylene ether as a penetrant are added; and with the pretreatment process, the bright and full subsequent dyeing and the good color fastness can be ensured, the good whiteness and the good impurity removing effect can be achieved, and the method is suitable for production.

Description

technical field [0001] The invention relates to the field of cheese dyeing, in particular to a treatment method for cheese before dyeing. Background technique [0002] Package yarn needs to be treated before and after dyeing. The purpose of pretreatment is to effectively remove various impurities contained in it, improve whiteness and wettability, and enhance dyeability without damaging the components. Light boiling and heavy bleaching are used in the existing pre- and post-treatment processes, but the current light boiling and heavy bleaching process cannot guarantee the subsequent dyeing effect very well. Therefore, it is very important to solve the above problems. Contents of the invention [0003] In order to solve the above problems, the present invention provides a treatment method before cheese dyeing, which adopts the process of middle boiling and middle bleaching, adding 2-4g / L of NaOH, 6-8g / L of hydrogen peroxide, 4-8g / L of high-efficiency Oxygen bleaching non-...
