Preparing method of improved melamine resin essence microcapsule finishing agent

Abstract

The invention discloses a preparing method of an improved melamine resin essence microcapsule finishing agent. The method includes the step of encapsulating essence through an in-situ polymerization method and an interface polymerization method with styrene-maleic anhydride copolymer as the emulsifying agent, essence as the capsule core and melamine resin and polyacrylate as the wall materials toprepare melamine resin essence microcapsules. The self-adhesive double-wall essence microcapsules prepared through the safe and environment-friendly preparing method have the solid content of 35-38% which is 10-15% higher than the solid content of other essence microcapsules on the market. Dual-layer wall constructing is conducted through the in-situ polymerization method and the interface polymerization method, the essence wrapping rate can reach 91-95%, and the product emulsion has high stability. The self-adhesive double-wall essence microcapsules have the unique advantages of microcapsulesand have self-adhesion performance, and the cotton fabric finishing process is simplified. The finished cotton fabric has a good fragrance depositing effect, the standing fragrance depositing time can reach 8 months, and the cotton fabric can still keep the pleasant fragrance after being washed with water 12 times.

Description

technical field [0001] The invention belongs to the technical field of textile finishing, and in particular relates to a modified melamine resin essence microcapsule finishing agent prepared by in-situ polymerization, with low methyl etherified melamine resin as the wall material and essence as the core material. Preparation. 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...

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.
