Abstract
The invention relates to a preparation method of microencapsulated nylon fragrant masterbatch, and belongs to the field of functional textile production. The method comprises the following steps: dissolving essences into an organic solution containing a polyurethane prepolymer, mixing with a water solution containing a polyethylene glycol emulsifier; adding proper superfine sodium phosphate, then carrying out full emulsification and reaction in a homogenizer, filtering and washing after the reaction is ended, and drying and crushing a filter cake to obtain the fine powder containing the essences; and fully mixing the obtained fine powder with low-melting point polyamide powder and a dispersing agent by a high-speed mixer, and then feeding the mixture into a double screw extruder to extrude, water-cool and chop, so as to obtain the microencapsulated nylon fragrant masterbatch. The microencapsulated nylon fragrant masterbatch prepared by the method is stable in performance, and good in compatibility with a spinning material by a spinning test; the physical indexes of produced polyamide fragrant fiber achieve the design effect; and the requirements of the majority of users are met.
Description
technical field [0001] The invention relates to a microencapsulated nylon aromatic masterbatch and a manufacturing method thereof, belonging to the field of functional textile production. Background technique [0002] Due to the development of science and technology and the improvement of people's living standards, people's pursuit of a better life is no longer limited to food and clothing. The requirements for functional textiles are getting higher and higher. Textiles that can continuously emit bursts of fragrance are also favored by people. of favor. [0003] The aromatic masterbatches in the prior art are prepared from polypropylene with a low melting point. Due to the poor compatibility between nylon and polypropylene when spinning aromatic nylon fibers, the mechanical properties of the fibers are affected to a certain extent. [0004] For the preparation of aromatic chemical fibers, the Chinese patent CN102618960A adopts the process of post-processing the fibers afte...
