Embodiment

[0022] The above indicators can meet the weaving and wearing requirements.

[0023] The quality of wrapped yarn is mainly evaluated by the uniformity of wrapping and yarn strength:

[0024] (1) The wrapping uniformity is mainly determined by the ratio of the outer fiber and the twist of the core yarn. The higher the content of the outer fiber, the better the wrapping uniformity; within a certain range, the higher the design twist, the better the wrapping uniformity ;

[0025] (2) Since the wrapped fiber is wrapped in the outer layer in a spiral shape on the surface of the yarn, the angle between the fiber and the yarn axis is large, the cohesion between the fibers is small, and the contribution to the yarn strength is small, and the strength of the wrapped yarn is mainly It is determined by the cohesion force between the core fibers. The core yarn fiber has high strength, large twist, large cohesion force and high yarn strength.

[0026] Adopt the advantage that the p...

Abstract

The present invention discloses a production method of short fibre wrapped composite yarn and its equipment. Said invention is implemented by using spinning frame and wrapping device, and its production method includes the following steps: raw material, scotching, carding, drawing, roving, spinning and doffing.

Description

[0001] Application field [0002] The invention relates to a spinning technology, in particular to a production method and a device for short fiber wrapped composite yarn. Background technique [0003] In recent years, the types of composite yarn production technologies invented and industrialized in the world mainly include: core-spun yarn, wrapping yarn, siro spinning, sirofil spinning, etc. The production principles of these types of products are different, the product styles are different, and the application fields are diverse. Among them, the core-spun yarn refers to a yarn or filament as the core, which is twisted together with another outer fiber to form a yarn. The characteristic is that the output length of the core yarn and the outer fiber is the same during twisting, and the core yarn is not exposed. , the production methods include air-jet spinning, friction spinning, modified ring spinning, etc. Wrapped yarn refers to a filament as the core, and another outsourc...
