Quality assessment in spinning mills. II. Process control and assessment of outogoing material

The article discusses the importance of quality monitoring during production in yarn spinning mills as well as the assessment of the finished product. The subjects covered include on-line and off-line process monitoring and the application of control charts to assess machine performance with respect to cleaning efficiency, cleanability, n..

Mew summer fabric from Kanebo Spinning

Japanese company, Kanebo Spinning Corp, has developed a translucent voile cotton/polyester fabric for summer apparel applications. It exhibits a light, soft handle and special finishing gives it superior pleatability and wrinkle resistance. The plan is to use the new fabric in women's dresses and brouses and men's shirts. The cotton used ..

Polyester high-speed spinning

Remarkable success has been achieved in recent years in the field of high-speed spinning. It is now possible to produce yarn at spindle speeds far in excess of 22 000 rpm. Most attention to date has been focused on the processing of cotton. However, the manufacture of 5.5 million tonnes p.a. of pure man-made yarns also represents a substa..

Spinners aggressively taking on environmental issues

The increasing interest of Japanese spinning companies in environmentally friendly technology and products is noted. Shikibo is to promote the development of cotton varieties which use less agricultura chemicals and to promote recycling and resource saving activities more. Daiwabo is also looking to expand in the area of 'chemical free' o..

Details are reported of a project entitled 'Flexibility-orientated control information systems for the small/medium sized sector of the textile industry' carried out by the Martin Luther University, Halle-Wittenberg, Germany in cooperation with CuBuss GmbH. The project investigated and modelled the determination of raw material requiremen..

Method and apparatus for producing tufts from different yarns in longitudinal lines

A tufting machine for tufting yarns into a backing material comprises front loop pile loopers arranged across the width of the machine, rear cut-pile loopers which are spaced apart from the front loop-pile loopers, a first set of front needles arranged between the front and rear loopers, and a second set of rear needles arranged between t..

Cut-resistant yarn

Hoechst Celanese Corp. has created a yarn that is resistant to both cutting and choppig. Made from at least two different kinds of fibre: the first has a modulus of more than 300 gpd and a tensile strength of more than 10 gpd; the second is a semicrystalline fibre filled with particles, gloves made using this yarn have a softer handle and..

The trial production of hand spinning robot based on consideration of hand spinning and its evaluation (Japanese)

Hand spinning has features that it is suitable for production of a lot of kinds of yarn on small quantity and the shape of the yarn can be changed easily. But this spinning method is hardly used at present because the spinner has to have a professional sk

Chossing the right top for spinning

This apper introduces a prediction tool - Sirolan-Yarnspec - which can be used in selecting tops which will meet the spinner's needs. Yarnspec allows the user to gauge expected spinning performance and yarn properties for any given pure wool worsted yarn.
