A hair-proof device suitable for twisting multi-F high-elastic yarn

Abstract

The present invention provides a device for preventing hair strands from being twisted for multi-F high-elastic yarns. The device comprises a metal wire barrel, the outer surface of which is provided with a spiral wire groove, the side surface of which is fixedly connected to a lower support plate, the upper surface of which is fixedly connected to a lateral support rod, the side surface of which is provided with a sliding groove, and the upper surface of which is fixedly connected to a cutting device. The left and right positions of the cutting device are moved by a first wedge-shaped limit block, thereby avoiding the problem of low precision caused by directly adjusting the position of the cutting device by bolts. After the cutting device processes the hair strands, the hair strands can be separated from the yarn by the partial airflow separated by the annular air outlet pipe. The remaining airflow is combined with the elastic device to ensure the tension of the yarn while avoiding the occurrence of hair strands.

Description

Technical Field

[0001] The invention relates to the technical field of anti-hair yarn devices, in particular to an anti-hair yarn device suitable for twisting multi-F high-elastic yarns. Background Art

[0002] Multi-F high-strength yarn twisting is a textile process used to produce yarn with high elasticity. The process typically involves twisting two or more yarns together and then twisting them to increase the yarn's elasticity and durability. In this process, the yarn is first passed through a series of tensioning devices and twisters to twist the two or more yarns together. These twisted yarns are then passed through a twisting machine for twisting, making them stronger and more elastic. The advantage of multi-F high-strength yarn twisting is that it can produce yarns with greater elasticity and durability than single yarns and can be used to make a variety of clothing, sports equipment, and other textiles. The disadvantage is that it requires more processing steps and equipment, and requires anti-linting treatment.

[0003] A twisted anti-tangle device, often called an anti-tangle loop, is used to prevent lint during the spinning process. During twist spinning, the yarn is stretched and rotated, creating friction between fibers, which can lead to fiber breakage and lint. The anti-tangle loop creates a ring-shaped area on the yarn to prevent friction and reduce lint. The anti-tangle loop typically consists of one or more thin hooks attached to the spinning machine via one or more brackets. As the yarn passes through the anti-tangle loop, the hooks create a ring-shaped structure on the yarn, reducing friction.

[0004] However, the use of only annular structure results in limited anti-hair effect. Therefore, according to the applicant's invention, an anti-hair device suitable for twisting multi-F high-elastic yarn was invented, which solves the problem of easy hair generation and the inability to effectively handle hair after it is generated.
