Abstract

A viscose fiber used for the tip filter of cigarette with high tar filtering effect is one of curved viscose cotton fiber, curved viscose wooden fiber and curved viscose bamboo fiber. Its preparing process includes such steps as preparing viscose containing titanium oxide powder, spinning, stretching, water washing, desulfurizing with sodium sulfite, water washing, bleaching, dechlorinating, oiling and baking. Its spinneret's orifice has a shaped cross-section or a circular cross-section with a core.

Description

Technical field: [0001] The invention relates to a fiber tow, in particular to a viscose fiber for cigarettes, a manufacturing method thereof and a spinneret used therein. Background technique: [0002] The main health hazard of cigarettes is the tar in tobacco smoke. In order to reduce the tar in the smoke, cigarettes are equipped with filter rods. The filter rods currently used in the tobacco industry are filter rods made of acetate fiber tow or polypropylene fiber tow. , the former has a good defocusing effect and a pure taste, but its price is relatively high and it needs to be imported from abroad. The above-mentioned acetate fiber tow and polypropylene fiber tow are not easy to degrade and pollute the environment. Invention content: [0003] The purpose of the present invention is to provide a kind of viscose fiber for cigarettes and its manufacturing method and spinneret used. The cigarette filter rod made of this fiber tow has good tar reduction effect, pure smell...
