Embodiment 1

[0057] A. The chemical fiber raw material adopts domestic S904 high melt flow rate polypropylene pellets, and the raw material is placed in the raw material supply device. The discharge rate is 5g / min; the maximum temperature of the inner cavity of the centrifugal disc is 100°C. The polypropylene melt is melted through the inner cavity of the centrifugal disc and transported to the spinneret hole, and the rotational speed of the centrifugal disc is 1000 r / min. When the melt is ejected through the spinneret hole, it is drawn by the centrifugal force of high-speed rotation to form polyester ultra-fine filaments, and is deposited on the web forming curtain with the cooling air flow to form a centrifugal fiber web. The centrifugal fiber web mainly forms fiber bundles by self-bonding.

[0058] B. The polypropylene fiber bundle is transported to the feeding plate through the conveyor belt effect, and the feeding roller grabs and transports the polypropylene fiber bundle to the openi...

Embodiment 2

[0061] A. The raw material of chemical fiber is German Bayer / 192X 92 degree polyurethane plastic granules. The raw material is placed into the raw material supply device. The discharge rate is 5g / min; the maximum temperature of the inner cavity of the centrifugal disc is 100°C. The polyurethane melt is melted through the inner cavity of the centrifugal disc, and is transported to the spinneret hole of the outer cavity, and the rotational speed of the centrifugal disc is 1000 r / min. When the melt is ejected through the spinneret hole, it is drawn by the centrifugal force of high-speed rotation to form polyester ultra-fine filaments, and is deposited on the web forming curtain with the cooling air flow to form a centrifugal fiber web. The centrifugal fiber web mainly forms fiber bundles by self-bonding.

[0062]B. The polyurethane fiber bundle is transported to the feeding plate through the conveyor belt effect, and the feed roller grabs and transports the polyurethane fiber bu...

Abstract

The invention provides a centrifugal-friction spinning device. The device includes a centrifugal device, a conveying device and a friction spinning device. The centrifugal device is used for making the melt into tow fibers, the conveying device is used for taking the tow fibers and transporting them to a feeding hole of the friction spinning device, and the friction spinning device is used for coagulating and twisting the tow fibers into yarn. The invention aims to provide the device for conveying centrifugally received fiber bundles into the friction spinning device to comb and twist the fiber bundles into yarn, wherein the production process of chemical fiber yarn is greatly shortened, and the industrial demand of high-efficiency short-process one-step forming to produce synthetic yarn is satisfied. Moreover, the invention further provides a spinning method of the centrifugal-friction spinning device and the yarn produced by the centrifugal-friction spinning device.

Description

technical field [0001] The invention belongs to the technical field of spinning machinery, and in particular relates to a centrifugal-friction spinning device and a yarn-making method carried out therewith. Background technique [0002] In recent years, domestic polyester production and melt direct spinning technology have made great progress in localization, providing a solid technical and equipment guarantee for the rapid growth of my country's chemical fiber production. Domestic 70t / d, 120-150t / d polyester staple fiber complete sets of equipment have been exported to several countries in North Africa and South Asia. It can be said that the level of my country's chemical fiber engineering technology has also been greatly improved. However, the strength of chemical fibers is insufficient, and it needs to be twisted into yarns to be widely used in industries. At present, the production and preparation process of chemical fiber yarn in the market is cumbersome. First, the po...
