Method for preparing melamine resin essence microcapsule finishing agent

Abstract

The invention discloses a method for preparing a melamine resin essence microcapsule finishing agent. The method comprises the following steps: a styrene-maleic anhydride copolymer is used as an emulsifier, essence is used as a capsule core, melamine resin and polyacrylate are used as wall materials, the essence is encapsulated with an in-situ polymerization method and an interfacial polymerization method respectively, and melamine resin essence microcapsules are prepared. Self-adhesive double-wall essence microcapsules are prepared with a safe and environment-friendly preparation method, andthe solid content of the microcapsules is 35%-38%, which is 10%-15% higher than the solid content of other essence microcapsules on the market. Double-layer wall building is performed with the in-situpolymerization method and the interfacial polymerization method, the essence encapsulation ratio can reach 91%-95%, and the product emulsion has good stability. The self-adhesive double-wall essencemicrocapsules have the self-adhesive property while maintaining the unique advantages of the microcapsules, and the finishing process of cotton fabric is simplified. The finished cotton fabric has good fragrance retention effect, fragrance can be retained for 8 months after standing, and the pleasant fragrance can still be maintained after water washing is performed 12 times.

Description

technical field [0001] The invention belongs to the technical field of textile finishing, and specifically relates to a method for preparing a melamine resin essence microcapsule 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...

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.
