Description
TARIFNAME BIR KOR IPLIK ÜRETIM SISTEMI Teknik Alan Bu bulus, tekstil sanayide öz ve sarim liflerinin çekim karakterli elektriksel alan etkisiyle birlestirilmesiyle olusan kor ipliklerinde bulunan tüylülük ve düzgünsüzlük degerlerinin iyilestirilerek iplik kalitesinin arttirilmasini, kompakt bir iplik yapisi elde edilmesini saglayan bir kor iplik üretim sistemi ile ilgilidir. Önceki Teknik Ring iplik makinesinde özlü (çekirdek) iplik üretimi; Egirrne islemi sirasinda özdeki filament ön sevk silindirleri tarafindan beslenmekte ve çekime ugrayan fitilin öz kismina yerlestirilmektedir. Sevk silindiri, metal telin düzgün bir sekilde egrilmesi ve hep öz kisminda kalmasini saglamaktadir. Bu sayede özdeki filament sürekli olarak manto lifleri tarafindan sarilmakta ve ipligin iç kisminda kalmaktadir. Çekime ugrayan fitilin egirme gerilimi çikis silindirlerin tutma noktalarindan ayrildiginda az miktarda azalma göstermektedir.

DESCRIPTION A KOR YARN PRODUCTION SYSTEM Technical Area This invention is an electrical field with attractive characteristics of core and winding fibers in the textile industry. The hairiness and the hairiness in the core yarns formed by combining the Increasing the yarn quality by improving the unevenness values, a compact It relates to a core yarn production system that provides yarn structure. Prior Art Core yarn production in ring spinning machine; During the spinning process The core filament is fed by the front delivery rollers and It is placed in the core of the wick. The delivery roller ensures that the metal wire is evenly It ensures that it bends and always stays in its own part. In this way, the filament in the core it is constantly surrounded by the mantle fibers and remains in the inner part of the yarn. The spinning tension of the drawn roving comes from the holding points of the output cylinders. shows a slight decrease when separated. Twisting and winding operations Thanks to this, the filament in the core is surrounded by staple fibers and attached to the core of the yarn. is settled.
Kor iplik üretiminde karsilasilan en önemli problem özdeki filament ya da stapel liflerin dis katmandaki sarim lifleri tarafindan tam olarak kapatilamamasidir. Çekirdekteki bu açik kalan noktalar iplikte deformasyonlara yol açmaktadir. Bu deformasyona barber-pole efekti denilmektedir. Bu nedenle olusan iplik kalitesinin olumsuz etkilenmesi kumasa da yansimaktadir. Özellikle boyama sonrasi kumasta renk farkliliklari, lekelenmelere sebep olmaktadir. 28797.07 Özdeki filamentin tam olarak kapatilamamasinin sebepleri; özdeki filamentin tam olarak merkezlenememesi, filament etrafina sarilan fitilin kesitteki lif sayisi yetersizligi, büküm miktari, ve merkezdeki rijit ve sabit filamentin, hareketli ve akiskan kesikli liflerle kaçinilmaz uyumsuzlugu nedeniyle düzenli olarak lif demetince sarilamamasi oldugu tespit edilmistir. The most important problem encountered in core yarn production is the core filament or staple. is the inability of the fibers to be completely covered by the winding fibers in the outer layer. These open points in the core cause deformations in the yarn. This The deformation is called the barber-pole effect. Therefore, the resulting yarn quality Its negative impact is also reflected in the fabric. Especially on fabric after dyeing Color differences cause staining. 28797.07 The reasons why the filament in the core cannot be closed completely; complete filament cannot be centered properly, the number of fibers in the cross-section of the roving wrapped around the filament insufficiency, amount of twist, and the rigid and fixed filament in the center, moving and fiber regularly due to its inevitable incompatibility with fluid staple fibres. It was determined that he could not be hugged by the bundle.
