Abstract

The invention relates to a batch ring spinning nanofiber / short fiber covering yarn device and method. The device comprises a ring throstle, the ring throstle comprises a front rubber covered roll (1),a front roller (8), a first insulating plate (2), a directed and fixed point deposition device (3), a spun yarn winding device (4), a yarn guide hook (7) and a single needle type electrostatic spinning device (6), wherein a front roller jaw is formed by the front rubber covered roll (1) and the front roller (8), the single needle type electrostatic spinning device (6) is arranged between the front roller jaw and the yarn guide hook (7), the directed and fixed point deposition device (3) is arranged below the single needle type electrostatic spinning device (6), the first insulating plate (2)is arranged below the front rubber covered roll (1), and the yarn guide hook (7) is connected with the spun yarn winding device (4). The deposition device is optimized, a nanofiber bundle is introduced into a yarn core, and the problem that conventional nanofiber and short fiber compound resultant yarn is easy to abrade and poor in durability in the follow-up processing and usage processes is effectively solved.

Description

technical field [0001] The invention belongs to the field of textile processing devices and methods, in particular to a device and method for batching ring-spinning nanofiber / spun core-spun yarns. Background technique [0002] The functionalization of textiles has always been one of the research hotspots in improving the grade and added value of textile products and expanding the application field of textile products. Compared with traditional textiles, functional textiles not only meet the needs of people to wear clothes and cover their bodies in the past, but also endow them with more functionality, which enriches the application range and application fields of traditional textiles. Promoting textile technology innovation has important guiding significance. [0003] Electrospinning, as an emerging technology capable of continuously preparing micro-nanofibers in batches, has become the most widely used method for preparing nanofibers. The diameter of nanofibers prepared b...
