Effect of Staple Strength on Spinning Performance and Yarn Quality of Superfine Wools

A processing trial was conducted at CSIRO comparing three batches of 17 µm, superfine fleece wool, collected from sale lot samples and matched for fiber properties but not staple strength. The three batches were compiled from auction display samples to have average staple strengths of 24, 32 and 43 N/ktex and were converted to top, yarn, ..

Exploratory Work on the Spinning Condition of the Structure of Staple-core Twin-spun Yarns

In order to design and develop novel-spun yarns with good functionality, we investigated how to construct a core-sheath structure adapted from a multilayered structure of triplet- spun yarn and/or made from a twin-spun yarn with core-staple fibers using an experimental ring-spinning frame. The results were follows: (1) staple-core twin-sp..

Fibrous Materials as Soft Matter

This paper proposes a new type of soft matter, namely fibrous materials. The common characteristics of soft matter that are shared by fibrous materials, such as the multiphase composition, porous and highly deformable structures, and the non-negligible contributions of entropy to the material behavior are illustrated. More importantly, so..

Torsion of Fibers of an N-sided Regular Polygonal Cross-Section

For fibers whose cross-section is an n-sided regular polygon, torsion constant, maximum stress, and torsion shape factor have been obtained in closed form. The solution is expressed in terms of the coefficients of the mapping function which maps the interior of a unit circle into the interior of an n-sided regular polygon. Conformal mappi..

Odor Retention on Apparel Fabrics: Development of Test Methods for Sensory Detection

A method for collecting axillary odor on nine knit fabrics was developed and odor intensity determined using a panel of assessors. Two methods, one involving paired-comparisons in the quad analysis method and the other a line scale, were investigated to determine if differences in intensity of odor retained on the fabrics varying by fiber..

Investigating the Applicability of Metal Ion Implantation Technique (MEVVA) to Textile Surfaces

Polyethylene terephalate (PET) samples were modified by Cu, C, Ti, and Cr implantation using a metal vapor vacuum arc (MEVVA) implanter. The ions were implanted at an accelerating voltage of 30 kV with a dose ranging from 1 × 1014 to 1 × 1017 ions/cm2. In the first part of this study, Cu ions were implanted to improve the electrical prope..

Development of a Tool to Evaluate the Comfort of a Baseball Cap from Objective Pressure Measurement: (I) Holding Power and Pressure Distribution

A tool to evaluate the subjective wearing comfort of baseball caps from the objective measurement of pressure was developed. Comfortable fit-ability index (CFI) and holding power were defined to represent the subjective wearing comfort of caps. As a preliminary step to define the CFI, average pressure, pressure distribution and standard d..

Development of Nursing Care Sheets of Cellulosic Nonwoven Fabrics for Aging Society

For care of the elderly in a rapidly aging society, a new type of nonwoven fabric care sheet made from cellulosic fibers laminated with a plastic film has been developed. Fiber orientation, friction, tensile strength, local deformation distribution during a tensile test and water absorbency were examined, with a view to practical applicat..

2011년 1/4분기 세계 실과 원단 생산량 감소

2011년 1/4분기 동안 세계 실과 원단의 생산량은 2010년 1/4분기 이후 증가 추세였음에도 불구하고 지난 분기 대비 감소하였다. 전년 대비 세계 실과 원단의 생산량은 계속적으로 증가하고 있다. 지난 분기 대비 실 생산량은 2011년 1/4분기 동안 전세계적으로 11.3% 감소하였다. 통계 자료에 따르 면 아시아와 유럽, 남아메리카에서 각각 12.2%, 2.6%, 0.1%씩 떨어..

인도, 2014년까지 섬유수출 2배 목표

인도 상공회의소 연방 장관인 Mr. Anand Sharma는 2014년까지 4,500억불의 수출을 달성하기 위한 계획의 하나로 섬유수출을 2배 늘리는 것을 제안하였다.
