Nozzle (1) for manufacturing knotted yarn (11), having a yarn duct (2) in which knots are producible with the aid of air entanglement. The nozzle includes at least one air bore (3) having a longitudinal axis (A), which merges with the yarn duct (2) in a merging opening (4). Air is introducible into the yarn duct (2) through the air bore. The longitudinal axis (A) of the air bore (3) is disposed at an angle of less than 90, preferably 65-85, particularly preferably 78 in relation to a conveying direction (B) of the knotted yarn (11). A baffle face (5) is configured on the opposite side of the merging opening (4) of the air bore (3) in the yarn duct (2), so as to be substantially perpendicular in relation to the longitudinal axis (A) of the air bore (3).

A lyocell material for a cigarette filter and a method of manufacturing the same are disclose. The lyocell material which is biodegradable and eco-friendly can be manufactured by crimping lyocell multifilaments to obtain a crimped tow.

Multi-component fibers or filaments that are ribbon shaped are provided having polymer components positioned in a side-by-side fashion. For example, the multi-component fibers may be bicomponent fibers having ribbon shape. The polymer components of the fibers are selected to have differential shrinkage behavior. Nonwovens are also provided that are manufactured from such ribbon shaped multi-component fibers or filaments.

A hollow polyester long fiber has a cross-sectional hollowness ranging from 20.0% to 45.0%, the long fiber in natural state being of a three-dimensionally crimped shape, and the radius of curvature of the crimped shape being 10.0 mm to 50.0 mm. The fluffy processed tows obtained by processing the hollow polyester long fiber have high fluffiness.

Staple fibers and filament yarns formed from cellulose esters, such as cellulose acetate, are described herein, along with methods of making the fibers and their use in nonwoven fabrics and articles. The filament yarns and fibers described herein may be coated with at least one finish and, in some cases, may be coated with two or more finishes selected to enhance the properties of the fibers. Staple fibers as described herein may be used to produce nonwoven webs that are strong, soft, absorbent, and biodegradable, and may be used in wet or dry nonwoven articles for a variety personal care, medical, industrial, and commercial applications.

This invention relates to a lyocell material for a cigarette filter and a method of manufacturing the same, wherein the lyocell material which is biodegradable and eco-friendly can be manufactured by crimping lyocell multifilaments to thus obtain a crimped tow.
