Embodiment 1

[0056] Select the lifting agent of Example 1 in the first group of dry rubbing fastness improving agent embodiments, and the treatment process adopts a padding process, and the described dry rubbing fastness improving agent is added with water to be mixed with a concentration of 30g / L padding treatment solution , into the padding tank.

[0057] Textiles are subjected to the padding process of two dipping and two rolling, the liquid rate is 90%, pre-dried, baked at 130°C for 2 minutes, and the padding treatment is completed to obtain the superfiber scarlet fabric treated with the dry rubbing fastness improving agent.

[0058] Of course, the curing temperature and curing time can be appropriately adjusted according to the variety and quality of the textiles, as long as the padding effect of the agent treatment solution is solidified and improved through the curing process.

[0059] The superfiber scarlet fabric treated with the dry rubbing fastness enhancer was tested on the dry...

Embodiment 2

[0061] The improving agent of Example 1 in the first group of dry rubbing fastness improving agent embodiments is selected, the treatment process adopts the dipping method, and the dosage of the dry rubbing fastness improving agent is prepared according to 3% of the weight of the fabric to be treated.

[0062] Add water to configure the impregnating treatment solution, using a bath ratio of 1:20, add the fabric to the impregnating treatment solution at room temperature, raise the temperature to 50°C, and treat for 30 minutes. Take it out and dry it, then bake it at 130°C for 2 minutes.

[0063] Of course, the curing temperature and curing time can be properly adjusted according to the variety and quality of textiles, as long as the impregnation effect of the agent treatment solution is solidified and improved through the curing process.

[0064] The silk fabrics treated with dry rubbing fastness enhancer were tested on a rubbing fastness tester. The dry rubbing fastness of un...

Embodiment 3

[0066] The improving agent of Example 1 in the first group of dry rubbing fastness improving agent embodiments is selected, the treatment process adopts the dipping method, and the dosage of the dry rubbing fastness improving agent is prepared according to 5% of the weight of the fabric to be treated.

[0067] Add water to prepare the dipping treatment solution, the bath ratio is 1:10, add the fabric to the dipping treatment solution at room temperature, raise the temperature to 60°C, and treat for 30 minutes. Take it out and dry it at 130°C for 2 minutes.

[0068] The woolen fabrics treated with dry rubbing fastness enhancer were tested on a rubbing fastness tester. The dry rubbing fastness of untreated rough wool fabric (black) is grade 2, and the dry rubbing fastness of wool wool fabric (black) after the impregnation treatment is grade 4.

Abstract

The invention discloses a textile dyeing substance dry friction fastness improving agent, a preparation method thereof, and an improving technology. The improving agent is composed of sulphobetaine type ampholytic surfactant, crosslinkable epoxy group condensate, polyethylene emulsion, and diglycol. The preparation method comprises the following steps: preparing a sulphobetaine type ampholytic surfactant in advance, adding the surfactant into a reactor, and heating under stirring to dissolve the surfactant; carrying out water bath at a temperature of 80 to 90 DEG C, stirring, cooling, and saving for later use; adding diglycol, polyethylene emulsion, and crosslinkable epoxy group condensate in sequence, evenly mixing, and finally filtering to obtain the improving agent. The invention also provides a unique padding technology and impregnating technology using the provided improving agent. The provided improving agent, preparation method, and processing technology are developed though long-term research, development, and practices, can effectively improve the dry friction fastness of textile dyeing substances, and fulfill the technical blank for improving the dry friction fastness in the textile post-treatment.

Description

technical field [0001] The invention relates to a textile auxiliary agent and its preparation method and application process, in particular to a preparation process of an agent for improving the dry rubbing fastness of dyed textiles and a process for improving the dry rubbing fastness. Background technique [0002] Whether the color fastness of textile dyeing can meet the standard is related to many factors. In addition to the type of dye used and the dyeing process, it also has a lot to do with the structure and surface shape of the fabric. Among the many color fastness indicators, the rubbing fastness of textiles is one of the most difficult problems to solve at present. In the traditional finishing process of dyed products, color fixing agent Y, color fixing agent M, etc. are used for color fixing treatment in order to improve the color fastness. The color fastness of the dyed matter, including the rubbing fastness, but because the color fixing agent Y, the color fixing a...
