TH20041B - Fluffy textured yarns and methods for producing such threads. - Google Patents

Abstract

What was revealed will be the spun-like texturized long fiber yarn which has been Manufactured by joining together of at least two elongated yarn elements. Each element has one closure. And folding this thread onto itself during the movement. That goes in that way The thread will scrape itself. And later take this thread through the twisting process. The final strand, wherein a fraction of the single strand that makes up this total strand, is obtained. Cut into short fibers And at least one end of each of these short fibers will be firmly bolted to this strand. By the way of the first twist or the last twist Either in such a way that it will emerge from the surface of the total filament yarn, thus being fluffy and which Textured long fibers have 100 to 400 threads, each from 1 to 5 mm long and 30 or more fluff, each from 1.5 to 5 mm long. Respectively, per meter and has a strength of 4.7 to 6 g of thread / denier. Yes The texture of this invention has a fluff and fluffiness similar to that of spun yarn and is Benefits for producing knitted or nonwoven fabrics with a soft touch and feel for a high quality layer, this textured yarn also has a greater thread toughness than that of conventional spun yarn. Plain or shaggy yarn that is also natural and will also give a touch And the feel is similar to that of spun yarn, hence it is also useful as Sewing thread with excellent high-speed sewing performance.

Claims (4)

1. Long-fiber yarn with a spun-like texture that is produced by using The joining of at least two total elongated yarn elements together with one strand and these yarns are carried through the final twist. Where a portion of a single long fiber is Assembled into a long fiber yarn, this total will be cut to short fibers. And at the very least end One side of each short strand is secured to this textured long yarn by Way of first twisting or one of the last twisting, hence to provide To have fluff emerging from its surface as well And this long-textured yarn has 100 to 400 strands of shag, each from 1 to 5 mm in length and 30 or more shag, each of which is From 1.5 to 5 mm, respectively, per meter and will have a strength of thread from 4.7 to 6 g / Denier. 2. Textured long filament yarn with spun-like shag according to claim 1, where each component of the total filament yarn constitutes a specific component. 30 to 300 single strands, comprising at least two types of Long fibers are the fineness of one long strand involved, which are different from each other, in which the thinner long fibers are essentially cut into shorter fibers. 3. A method for producing spun-like textured spun-like yarns, which include: (a) the joining of at least two strands of filament yarn, each of which Lines have been Making a first strand with these threads in the first twisting step, (b) making these bundles form a loop. And this suspension surrounds the lead in such a way that The thread that travels along the path of the thread leading into this section crosses the thread. The thread travels back from this section at the speed of movement of the thread from 3 to 100 m / min. Thus, this twisting and pulling of the thread is induced. In order to prepare the fluff, and after that (b) the threaded yarn is passed through the final twisting step. Final twist 4. Method for the production of spun-based spun-like textures yarn. Clause 3 The direction of the twist which is caused by this cross is directed in the direction. Which is the same as the direction of this thread
