Method for preparing melamine resin finishing agent

Abstract

The invention discloses a method for preparing a melamine resin finishing agent. The method comprises respectively carrying out encapsulation on essence as a capsule core through melamine resin and polyacrylate as shell materials and a styrene-maleic anhydride copolymer as an emulsifier through an in-situ polymerization method and an interfacial polymerization method. The method can prepare self-adhesive double-walled essence microcapsules with solid content of 35% to 38%, which is 10% to 15% higher than those of other solid microcapsules on the market, through safe and eco-friendly processes.Through the in-situ polymerization method and the interfacial polymerization method, double-layer wall building is realized and the essence encapsulation rate is 91-95%. The product emulsion has goodstability. The self-adhesive double-walled essence microcapsules have self-adhesive properties while maintaining the unique advantages of microcapsules and simplify the finishing process of cotton fabrics. The finished cotton fabric has a good fragrance retention effect, can be stood for 8 months for fragrance retention and can still maintain the pleasant fragrance after being washed 12 times.

Description

technical field [0001] The invention belongs to the technical field of textile finishing, and specifically relates to a process for preparing a melamine resin finishing agent prepared by an in-situ polymerization method using low-methyl etherified melamine resin as a wall material and essence as a core material. Background technique [0002] With the development of the economy and the improvement of living standards, people's requirements for textiles have undergone great changes. From the past practical type to the decoration, enjoyment, and health care type, textile perfuming conforms to this trend. Because scented textiles have the functions of antibacterial and insect repellent, covering peculiar smell, and making body and mind comfortable, they are generally liked by people. In ancient my country, there was the habit of sewing sachets on clothes; Europe has sprayed perfume on clothes since the Middle Ages as an elegant style, and later, there was a method of incense; fo...

Problems solved by technology

Traditional microcapsule technology usually uses physical methods to prepare various open-cell flavor microcapsules, and then uses adhesives and crosslinking agents to mechanically adhere the microcapsules to fabric fibers, and the fragrance retention time is not long; at the same time Due to the existence of the adhesive, the hand feeling is not good, which affects the comfort when wearing

[0004] However, the fragrance microcapsules sold on the market today often have disadvantages such as low packaging rate of fragrance, low mechanical strength of the capsule wall, short fragrance retention time, low affinity with fabric fibers, and difficult bonding.
