An apparatus for making a nonwoven fabric from thermoplastic plastic filaments has an air permeable deposit conveyor having a horizontal face displaceable in a horizontal travel direction and a spinneret above the conveyor for spinning the filaments and depositing the spun filaments on the deposit conveyor in a deposit area of the conveyor as a nonwoven web for conveyance in the travel direction. An extractor beneath the conveyor draws air or process air through the deposit conveyor in the deposit area in a main extraction area below the deposit conveyor and is delimited by, relative to the travel direction, upstream and downstream suction partitions. One of the partitions has an upper edge set at a predetermined vertical spacing below the conveyor equal to between 10 mm and 250 mm.

The present invention provides a composite ultra-high molecular weight polyethylene fiber and a preparation method thereof, wherein the method comprises mixing glass fiber, graphene slurry, UHMWPE powder and white oil, and then swelling to a molten state, then cooling into a gel-spun, and finally making the fiber from the gel-spun. The method of the present disclosure not only can solve the problem that the glass fiber has poor dispersibility in the case of high viscoelasticity of the ultra-high molecular weight polyethylene, but also can improve the cut resistance of the ultra-high molecular weight polyethylene fiber on the basis of ensuring the flexibility of the yarn.

An apparatus feeds a plurality of threads to rotating godets of a melt spinning machine including a manual injector (e.g., a main manual injector) and a cutting device. In order to be able to selectively feed the threads individually or as a bunch, a transfer device and a second manual injector (e.g., an auxiliary manual injector) are associated with the manual injector.

A spinneret is used to reduce filament breakage during spinning of multifilament yarn being stretched at a high stretch ratio. The spinneret has a first group of spinning holes with capillaries and a second group of spinning holes with capillaries. The capillaries of the second group of spinning holes have a lower length to diameter (L/D) ratio than the capillaries of the first group of spinning holes. All of the capillaries have the same diameter, which is 100 m or less.
