摘要:
The method of this invention comprises the improvement of using an open frame skein carrier with arms to loosely hang the yarn skeins. This allows a shorter total heat-setting time; eliminates kinks, and improves bulk and bulk uniformity of the yarn.

A quench system for spinning multifilament synthetic fiber using a fog in the quench stack is disclosed. The system and method comprisea. spinning synthetic multifilament fiber from the molten synthetic polymer through a spinnerette into a quench stack,b. quenching the freshly spun fiber in the quench stack with a combination of flowing air and airless atomized water in the form of a fog, andc. taking up the fiber onto a wound package,d. while controlling the air flow, controlling the formation of the fog, and removing any excess water droplets formed in the quench stack.
摘要:
This invention relates to method and apparatus to intermittently apply a treating fluid to a wad of yarn in a texturing device comprising intermittently injecting the fluid under pressure into at least one port at the texturing device and impregnating the yarn with the fluid for a period long enough for the fluid to coat, react, or bond with the yarn. Continuous injection can be used for chemically reactive agents, which do not affect yarn coloration.
摘要:
Preparation of a fluorocarbon compound used to make a soil-resistant yarn is improved by removing most of the impurities from the fluoro-carbon compound mass with heat and vacuum after the final washing step and then adding an emulsifier to the fluorocarbon compound mass so that the mass can be handled as a liquid concentrate rather than a tacky solid.
