Non-ironing crease-proofing agent and use method thereof

Abstract

The invention discloses a non-iron crease-resistant finishing agent and a use method thereof, aiming at the problem that the prior non-iron crease-resistant finishing agent has high requirements for raw materials used for synthesis or has no ideal non-iron effect. The non-iron crease-resistant finishing agent is composed of three portions that are packed separately, the first portion is composed of two-aldehydev compound, catalytizer, buffer, condensing agent and deionized water, the second portion is a compound containing boron, the third portion is carboxylic acid. The non-iron crease-resistant finishing agent has the advantages of outstanding non-iron crease-resistant performance, less yellowing and high strength reservation.

Description

technical field

[0001] The invention relates to the field of printing and dyeing auxiliaries, in particular to a non-ironing anti-wrinkle finishing agent and its application method. Background technique

[0002] In recent years, with the strengthening of people's awareness of environmental protection, formaldehyde-free non-ironing finishing agents have become an important research topic in the field of non-ironing finishing agents. At present, polycarboxylic acid is the formaldehyde-free finishing agent that has the most potential to replace N-methylol amide compounds, and wherein, butane tetracarboxylic acid (BTCA) has the best finishing effect, but due to its high price (approx. 10 times that of 2D resin), which hinders its industrialized large-scale production; citric acid (CA) is cheap, safe and non-toxic, but the finishing effect is not as good as BTCA, and there are problems such as yellowing and poor wash fastness, so it cannot be widely used.

[0003] Glyoxal series...

Examples

Embodiment 1

[0025] 100 parts of glyoxal (40%), 70 parts of aluminum sulfate, 10 parts of aluminum citrate, 400 parts of ethylene glycol, and 300 parts of deionized water are used to control the temperature of the material at 30°C with a constant temperature water bath, and stir for 0.5h. A light yellow translucent solution was obtained, and an appropriate amount of deionized water was added to adjust the mass concentration of the product system to 30%. Sodium perborate is 0.1% (to the working fluid wt%), and formic acid is 1.0% (to the working fluid wt%), and the two are directly added to the rolling groove working fluid when the fabric is processed.

Embodiment 2

[0027] 110 parts of glyoxal (40%), 100 parts of aluminum chloride, 20 parts of aluminum citrate, 420 parts of ethylene glycol, and 310 parts of deionized water are used to control the temperature of the material at 35 °C with a constant temperature water bath, and stir for 1 h. A light yellow translucent solution was obtained, and an appropriate amount of deionized water was added to adjust the mass concentration of the product system to 30%. Sodium perborate is 0.2% (to the working liquid wt%), and formic acid is 1.2% (to the working liquid wt%), and the two are directly added into the rolling groove working liquid respectively when the fabric is processed.

Embodiment 3

[0029] Mix 120 parts of glyoxal (40%), 90 parts of aluminum phosphate, 10 parts of aluminum tartrate, 460 parts of diethylene glycol, and 320 parts of deionized water. Use a constant temperature water bath to control the temperature of the material at 40 ° C. Stir for 1 hour to obtain light yellow Translucent solution, add appropriate amount of deionized water to adjust the mass concentration of the product system to 30%. Borax is 0.4% (to the working solution wt%), and formic acid is 1.7% (to the working solution wt%), and the two are directly added to the rolling groove working solution when fabrics are processed.
