CS230818B1 - A method for producing a fiber strand by tearing from multifilament chemical fibers - Google Patents

Abstract

The invention relates to a method for producing a fiber strand by tearing from multifilament chemical fibers, where the resulting strand contains effect components of chemical fibers, natural fibers or their mixtures, intended for the production of effect yarn. The essence of the invention lies in the fact that the effect components are mixed with multifilament chemical fibers before their tearing on the converter, after which they are torn together at a minimum of 100% elongation in the tearing zone. The invention can be used for a wide range of production of effect strands and yarns with new effects using various and waste textile raw materials.

Description

The invention relates to a method for producing a fiber strand by tearing from multifilament chemical fibers, the resulting strand comprising effect components of chemical fibers, natural fibers or mixtures thereof, for producing effect yarn.

The hitherto known method of producing fiber strands with various components of spun and non-spun fibers, carried out by mixing them in the bed, further by shaking, carding, drawing, eventually combing or blending individual fiber components in a strand or comb, is laborious, technologically and energy intensive.

With this method of production, it is possible to achieve only the effects of mill or knob effects, without significant color, non-material and shape differentiation of the effect, with low labor productivity and high production costs.

SUMMARY OF THE INVENTION It is an object of the invention to provide a productive production of a staple sliver with direct admixture of shredded effect components, fibers or their structures, for example, sliver, woven, yarn, thread, tows.

The principle of the invention is that the effect components are mixed with multifilament chemical fibers before they are torn on the converter and then tear together at a minimum of 100% elongation in the tear zone.

The admixed effect fiber component is applied to the converter strand of chemical fibers, for example polyacrylonitride, polyester or modified fibers. The converter strand is mixed, coagulated, for example 50% polyacrylonitride fibers and 50% polyester fibers.

The fibrous formations of the effect components are presented for converter processing by tearing in the form of a reel on a spool or loose, for example in a carton, a watering can or a bag.

The passage of partially or fully split effect fiber structures through the tearing converter due to the applied zone delays is provided by the basic material components of the shredded chemical fibers - cables.

The proposed method of converter production of strands of chemical fibers with effect components intended for yarn production and spinning effect allows to shorten the technological process of production with operations performed in the production of carded, blended, drawn or eventually combed strands such as bedding, fluffing, carding and the like completely new yarn effects that cannot be done by known technologies.
