Wrap yarn spinning device and preparation method of carbon fiber wrap yarn

Abstract

The invention relates to a wrap yarn spinning device and a preparation method of a carbon fiber wrap yarn. The wrap yarn spinning device comprises at least two sets of spinning units; each spinning unit comprises a core yarn feeding mechanism, an outer wrapping yarn feeding mechanism and an outer wrapping yarn straightening mechanism; and a wrap yarn formed by the previous set of spinning units serves as a core yarn of the next set of spinning units; the carbon fiber wrap yarn comprises the core yarn; the core yarn is sequentially wrapped with a first outer wrapping layer and a second outer wrapping layer; and the preparation method of the carbon fiber wrap yarn comprises the steps that the core yarn is supplied through the core yarn feeding mechanism of the first spinning unit and then sequentially penetrates through a first hole channel and a second hole channel, and the core yarn is supplied in the linear direction; the outer wrapping yarn in the first outer wrapping layer enters a yarn guiding device after being supplied through an outer wrapping yarn bobbin, the outer wrapping yarn straightening mechanism drives the outer wrapping yarn to rotate relative to the core yarn through the yarn guiding device and to spirally wind the outer wrapping yarn on the outer portion of the core yarn, and the core yarn wrapped with the first outer wrapping layer is formed; and according to the method, the second outer wrapping layer continues to be prepared outside the first outer wrapping layer, and the carbon fiber wrap yarn is formed.

Description

Technical field [0001] The present invention relates to the field of yarn production, and more particularly to a method for producing a yarn spinning apparatus and a carbon fiber bag. Background technique [0002] The yarn is also known as the wrapped yarn, which is a new type of yarn. It is a filament or short fiber as a yarn, an outsourced another filament or short fiber gauze, an outsourcing yarn according to a spiral The yarn is coated, and it is characterized by a uniform strip, the bullet is full, the yarn is smooth and the hair is small, strong, and less. The coated gauze is used to require high-elastic knitted fabric, partially used for machine fabrics, and is ideal yarns for high-grade thin hair, hemp fabrics, jacquard double weft knitted knitted knitted knitted knitted knitted knitted knitted knitted knitted knitted knitted knitted knitted knitted knitted knitted woven. According to the purpose, the covering yarn can select the appropriate core yarn and outsourcing yarn...

Problems solved by technology

[0004] In order to solve the above-mentioned technical problems, the purpose of the present invention is to provide a covered yarn spinning device and a method for preparing carbon fiber covered yarn. The covered yarn spinning device of the present invention has high spinning efficiency, simple process, and overcomes the single-layer The problem of the leaking core of the covering, and also overcome the problem of a single outer covering, the prepared carbon fiber covering yarn can have multiple functions at the same time to meet the different needs of users
