Functional yarn preparation method

Abstract

The invention belongs to the technical field of fiber and yarn preparation, and relates to a functional yarn preparation method. The functional yarn preparation method comprises the following steps that a, an electrostatic spinning solution is prepared; b, electrostatic spinning of nanofibers is carried out; c, the electrostatic spinning nanofibers are twisted; and d, the electrostatic spinning nanofibers are drafted and wound into yarns. The invention further provides a preparation method of the mint nanofiber and yarn, a preparation method of wormwood nanofiber and yarn and a preparation method of color-changing nanofibers and yarns. According to the functional yarn preparation method, superfine nanofibers can be prepared, the prepared nanofiber yarn is soft and high in weavability, and the preparation technology is simple in process and easy to operate.

Description

technical field [0001] The invention belongs to the technical field of fiber and yarn preparation, and relates to a preparation method of functional yarn. Background technique [0002] At present, in order to meet diverse needs, various functional yarns have been released on the market, such as mint yarns, mugwort yarns and color-changing yarns, etc., but the preparation of these yarns is insufficient. In view of this, there is an urgent need to develop a novel method for preparing functional fibers and yarns thereof. For example: [0003] 1. Mint yarn [0004] The green and natural peppermint oil has the functions of refreshing and relieving depression, cooling and fragrant, skin care and moisturizing, dispelling wind and heat dissipation, preventing typhoid fever, antibacterial, anti-inflammatory and anti-mosquito, aiding digestion, benefiting throat, resolving phlegm and relieving asthma, and removing peculiar smell. At present, the development of peppermint textiles m...

AI Technical Summary

Problems solved by technology

The main problems that exist: (1) the content of peppermint oil in the fiber is low, and the peppermint oil is difficult to release through the microcapsule wall and the thicker fiber diameter, causing the effect of peppermint to be difficult to fully and significantly exert; The mint fabric developed by this method has a hard feel and poor washability

The main problem exists: the toughness of the whole wormwood viscose fiber is not enough, and the functional components of wormwood are easily lost or damaged during the preparation process, resulting in an unsatisfactory effect

The color-changing fiber products prepared by post-finishing method and electroplating method generally have the defects of poor color fastness, hard hand feeling and poor durability.

Melt spinning method, mixing reversible discoloration materials with spinning masterbatches such as polyester masterbatch, polypropylene masterbatch, and polyethylene masterbatch to prepare color-changing masterbatches and melt spinning. At present, PP, PE, PET temperature-sensitive Changing silk, good color fastness and strong durability, the main problems are that the thickness of the silk is more than 150D, the content of discoloration substances is low, the color is light, and the hand feels hard, etc.
