Jute/cotton blends

The whole range of operations used in the spinning of cotton/jute yarns is investigated and costed. Softening and cutting of the jute, opening, blending with the jute, lap formation and carding are all discussed. The route then leads to ring or rotor spinning.

Ring && Rotor Spun Yarns.

Researchers investigated the tendency of breaking energes of both rotor spun and ring spun yarns to initially increase with an increase in twist density. Rayon fiber processed through a Shirley miniature card and drawframe yielded test samples. Preparatio

Spinning Microdenier Polyester Staple Fibre.

JCT Limited developed microdenier yarns of 0.5 and 0.8 denier. Tinting should not be used for JCT polyester 0.8 denier yarn. Rather, the manufacturer recommends color coding card and drawing cans and roving/ring bobbins. Blending the polyester and combed cotton at the mixing stage offers better carding performance and minimized risk of ro..

Process Optimization in Spinning Special Fibers.

A experiment to optimize process parameters in spinning high performance fibers sampled Nomex 455 and Karvin fibers. Nomex 455 comprises 95 percent meta-aramid and 5 percent para-aramid, and Karvin comprises 65 percent flame resistant viscose, 30 percent Nomex meta-aramid, and 5 percent Kevlar para-aramid. The experiment used a convention..

A study of the Mechanics of Fiber Straightening During Deposition in the Disc-Spinning Process. Part I: Theoretical Consideration.

A theoretical analysis of the dynamics of deposition in the disc spinning process examines the effect of the deposition action on fiber straightening for improved fiber extrusion and alignment in disc spun yarns. Researchers examine the idea of a fiber co

Manual of textile technology. II

Yarn-manufacturing processes for spun yarns are outlined. The principle of conventional yarn manufacturing methods is to introduce a twist into the yarn by yarn revolution. The major processes involved in cotton spinning are characterized, with illustrations. Yarn structures and properties are also described.

Cotton Spinning.

ITMA 1995 did not feature any revolutionary technologies in the area of cotton spinning, but focused on the optimization of individual process parameters. Systems for the removal of foreign matter included Jossy's Vision Shield, Trutzschler's Securomat, Zellweger's Optiscan, and Uster's Peyer Clearer. Improvements in ring spinning include..

Major Trends in the Short Staple Spinning Sector at ITMA 1995.

Although no major technological developments were exhibited at ITMA 1995 in the short staple spinning sector, important trends included the simplification of operations, particularly in information systems. Notable information systems at the exhibition were Barco's Sycotex and Marzoli's Plan Management. Automation and improvements in desi..

Automation in Textiles.

Automation of the production processes offers the European spinning industry high standards of quality and low production costs. Automation can increase production and reduce labor costs. Automation (automatic doffing and link cone winding) combined with the use of improved packages offers increased productivity. The automation on Marzoli..

방적공장에서의 공정 자동화

방적공장에서 대부분의 부 공정들에 대한 자동화 요소는 잘 알려져 있으며, 특히 캔과 패키지의 교환 장치, 사절 수선을 위한 자동화 장치는 널리 보급되어 있다. 그 반면 물류의 처리 및 운송을 위한 요소, 시스템 및 관련 켄테이너는 현재에도 아직 폭넓게 사용되지 않고 있다. 본고에서는 Rieter사의 방적공장에서의 부공정들간의 운송과 처리 시스템에 대한 설명..
