Problems solved by technology

Although through the above method, better aromatic fabrics can be obtained, if the amount of microcapsules added to the textile is small, the fragrance function cannot be guaranteed. During the process, due to friction, the microcapsules are easily destroyed, resulting in a decrease in aroma performance

[0028] The present invention provides a kind of preparation method of fragrant yarn, which comprises the following preparation steps:

[0029] S1: Take aromatic microcapsules with a weight percentage of 2-15:85-98 and mix them with a water-soluble resin solution, stir evenly to obtain an aromatic coating; disperse the aromatic microcapsules in a water-soluble resin solution to form an aromatic coating, wherein, The aromatic microcapsules are formed by coating the aromatic materials with melamine resin as the shell material by using microcapsule processing technology; the particle size of the aromatic microcapsules is 4 μm-6 μm; the aromatic materials are essences and plant essential oils. One: the water-soluble resin solution is a polyvinyl alcohol solution, and the mass ratio of polyvinyl alcohol to water in the polyvinyl alcohol solution is 1-3:6-12. Preferably, the weight percentage of aromatic microcapsules and water-soluble resin solution is 3:97; the mass ratio of polyvi...

Abstract

The invention discloses a preparation method of a aroma-sensing yarn. The preparation method comprises the following preparation steps that aromatic microcapsules are taken and mixed with a water-soluble resin solution, and uniformly stirring is conducted to obtain aromatic coating; a PET film or chemical fiber cloth is taken as a base material, and the base material is coated with the aromatic coating by adopting a coating process to obtain a aromatic film layer; the aromatic film layer is shredded to form aromatic filaments with the width of 0.1-1 mm; and 18d-900d yarns are taken, and the yarns and the aromatic filaments are wound together in a yarn covering or twisting mode to form the aroma-sensing yarns. According to the preparation method, the aromatic filaments with the microcapsules are combined with the yarns to form the aroma-sensing yarn, the yarns and the aromatic filaments are wound together in the yarn covering or twisting mode, the microcapsules in the aromatic filamentscan be protected, thus the situation that the microcapsules are damaged due to friction between objects in the processing process is greatly reduced, and the aromatic function of the aroma-sensing yarn is ensured.

Description

technical field [0001] The invention relates to the technical field of functional textiles, in particular to a method for preparing a fragrance-sensitive yarn and the fragrance-sensitive yarn. Background technique [0002] Yarn is made of two or more single yarns combined and twisted. It has a certain fineness and can be used for weaving, rope making, thread making, knitting and embroidery. Among them, it is used for textiles The yarn in the industry can also be called sewing thread. [0003] The aromatic fabric prepared by using the aromatic sewing thread can meet people's demands for fashionable, comfortable and hygienic clothing. In the early days, the method of adsorption was used to obtain aromatic fabrics, or the fragrance was added to the adhesive and applied to the surface of the fabric by coating. These methods of perfuming the fabric have a short fragrance retention time, especially after washing. will disappear. At present, in order to prepare aromatic fabrics ...
