Description
Technical field
The invention belongs to the flax spinning technical field, be specifically related to a kind of wet spinning hemp cloth and manufacture method thereof.
Background technology
At present China produces hemp cloth, employing be that dry-spun yarn is weaved and formed, the cloth cover filoplume is more, feel is relatively poor, body is heavier, people are in wearing process, the woven hemp cloth of dry-spun yarn has prodding and itching feeling to skin.
Summary of the invention
The present invention will solve that the lining feel of present dry-spinning hemp cloth is relatively poor, filoplume is more, skin is had problem such as prodding and itching feeling, and a kind of high-grade wet spinning hemp cloth and manufacture method thereof of utilizing wet-spun yarn to make is provided.
Wet spinning hemp yarn is because what adopt is roving degumming technology and wet spinning, and yarn strength is big, but poor flexibility, extend for a short time, and rigidity is big, so weaves the comparison difficulty according to common technology, have effective weaving process technology to produce.Wet spinning hemp yarn moisture adsorption and releasing speed is fast, to weave ambient temperature and humidity control require high, wet spinning hemp yarn wet powerful, in order to satisfy weaving of wet spinning hemp cloth, in weaving process, wet spinning hemp yarn is a moisture absorption process.
The present invention adopts following technical scheme to realize: the manufacture method of wet spinning hemp cloth, comprise wet spinning hemp yarn winder, dead twist, warping, sizing, weave, it is characterized in that:
