ITMA Review: Spinning.

At ITMA, Zinser, Rieter, Suessen, and other leading ring spinning machine manufacturers exhibited a new compact spinning technology, in which a pneumatic condensing zone follows the drafting zone and suction creates a thin sliver that eliminates the conventional triangular spinning zone. The resultant yarns feature more effectively bound ..

Jute Industrial Processing

To improve jute processing in India, researchers conducted an industry-wide survey, pilot plant experiments, and mill trials to identify specific quality parameter values for fiber selection, carding, drawing, and spinning. Tables describe a sampling plan for evaluating the properties of raw jute fibers; norms for morah weight; batch comp..

Imperfections in Yarn: Causes and Remedies.

Cotton yarn imperfections, such as thick places, thin places, and neps, are caused by poor quality raw materials, processing parameters, the condition of processing machinery, and mill practices and procedures. Raw material properties that influence yarn imperfections include micronaire, short fiber content, immature fiber content, and tr..

ITMA 1999 Paris 13th International Exhibition of Textile Machinery.

Howa machinery Limited exhibited its UAM ring spinning machine at ITMA 1999. Th UAM features a direct drive system; a special damper spindle for quiet machine operation; flexible speed changes; traveler break-in control; reliable automatic doffing with an incorporated yarn catching device; and an auxiliary triple draft apron.

Characterisation of Neps in Spinning Processes.

A study evaluated nep profiles from the raw material stage to the yarn stage and examined the effect of spinning parameters on nep size reduction for fine count and combed cotton. Critical nep size varied at the raw material stage for cotton of the same count between different mills. Nep size increased between the raw material stage and t..

Unevenness of yarns and preparatory materials. Part 1: Concept and causes

Discusses the parameters used to express yarn unevenness and how to control them. The effect of fibre properties and process parameters on the evenness of sliver, roving and yarn are outlined. The causes of yarn irregularity fall into four main groups: properties of raw materials; shortcomings in yarn making and preparation; defective mac..

Fibre to yarn relationships - a practical perspective

Several studies, which are surveyed in this article, have mapped the relationship of yarn quality to raw material quality. This paper reports on the results from a statistical survey of yarn quality that is achieved practically by spinning mills from given fibre properties. The results of this study are seen as useful for mills as a bench..
