Method for preparing roller brush fabric from thermoplastic fiber
InactiveCN109868542AHas the effect of hot melt adhesionNot fusion strongBristlePile-fabric loomsFiberEnvironmental resistance
The invention provides a method for preparing a roller brush fabric from thermoplastic fiber. A certain proportion of thermoplastic fiber serves as main fiber materials of upper-layer base cloth and lower-layer base layer, conventional fiber is used for connection of the upper-layer base cloth and the lower-layer base cloth, blank cloth is prepared through a machine knitting method, the upper-layer base cloth and the lower-layer base cloth have hot melting adhesion effects through pile cutting, heating and solidification, and the solidification and non-nap-off effects are achieved without gluing. The fabric can be used for a roller brush and a scrubbing brush, the environmental protection purpose is achieved by omitting the coating process, compared with the similar products, the fabric has fuller suede, a thick and solid hand feeling and non-silk-off and non-nap-off effects, and the solidification effect and the bottom stiffness are good.

InactiveCN107263203AEasy to useExtend your lifeMaintainance and safety accessoriesCold airMachine parts
The invention provides a cold air micro-quantity lubrication system. The cold air micro-quantity lubrication system is characterized by comprising a gas generator, at least one liquid generator, a gas converter and a micro-quantity lubrication ejector, wherein the gas generator communicates with the gas converter and conveys gas to the gas converter; the liquid generator communicates with the gas converter and conveys liquid to the gas converter; the gas converter converts gas into cold air; the micro-quantity lubrication ejector is mounted at the cold air output end of the gas converter, and the cold air and the liquid are ejected through the micro-quantity lubrication ejector after being mixed separately. The cold air micro-quantity lubrication system can release cold air to cool a machined part through a turbine refrigerating system when a workpiece is machined through the system, and the effect of cold working is realized.
