Numerical Study of the Three-dimensional Flow Field in Compact Spinning with Inspiratory Groove

In compact spinning with inspiratory groove, the computational fluid dynamic model, computed with parallel technologies and Fluent 6.3, was developed to simulate the flow field in the compact zone with 3D computational fluid dynamic technology. Flowing state, distributions of static pressure and velocity in the compact zone were character..

Sound Absorption Behavior of Knitted Spacer Fabrics

This paper presents an experimental investigation on the sound absorption behavior of knitted spacer fabrics. Both weft-knitted and warp-knitted fabrics were used in the study due to their different structure features. The weft-knitted spacer fabric used was composed of two varied plain knitted outer layers and one textured polyester mult..

Utilizing Scanning Electron Microscopy Stereoscopy to Explain the Wear Behavior of Latch Needles

Knitting needles are the main elements for the knitting process and they are continuously in contact with fibers, yarns and contaminants existing in the structure of the yarns. In this study, the wear occurring inside latch needle hooks was examined empirically to explain how it is affected by the type of yarn and the machine parameters. ..

Auto-generating Uniform Stochastic Web Images for Ink-jet Printing Textiles

Based on a kind of nonlinear scientific technology—weak chaos, we developed a parameterized program to generate various Uniform Stochastic Web (USW) images, and proposed the methods of transforming mapping function to obtain abundant colorful digital images for ink-jet printing. The ways to edit the images to be textile patterns were als..

Cluster-Spun Yarn — A New Concept in Composite Yarn Spinning

The aim of this work is to explore a new method for producing spun yarn on a modified ring spinning system which is called “clusterspun yarn”. Here, we describe the effects of the clustering of polyester multifilaments on the internal structure and properties of a composite yarn. Cotton fibers and polyester multifilaments were spun into..

Effects of Spinning Conditions on Shape Changes of Trilobal-shaped Fibers

The effects of spinning conditions on shape changes in the trilobal-shaped fiber spinning of poly(ethylene terephthalate) (PET) and polypropylene (PP) fibers were studied with a focus on spinning parameters such as mass flow rate, spinning temperature and take-up. Extrudate at the die-swell points along the spinline was obtained to invest..

방적의 면소재 ‒ 면의 새로운 부가 가치 가능성 아직 많아

  면화 가격은 높이 오르고 있는데 세계적으로 면사가 계속 부족하다. 신흥국(新興國)에서 수요가 계속 왕성하기 때문이다. 그런데 일본을 보면 방적 생산은 낮은 수준이 계속되고 있다. 이런 상황이 계속되고 있는 원인은 면제품 원료와 생산 코스트가 충분히 납득할 수 있게 부가 가치를 인정받지 못하고 있기 때문이라는 것을 모두가 알고 있다. 방적에게 중요한 ..
