Bicomponent yarns offer protection

Schappe Techniques are currently producing yarns made from a core of long staple fibres that are covered by a wrap of short staple fibres. During twisting a considerable bond is formed between two components making the yarns highly resistant to abrasion. Schappe Techniques adds that it has also developed hosiery yarns for knitting into pr..

The yarn is served (Italian) (Il filato a servito)

Wrap spinning machines produced by the Italian firm Menegatto are presented. Constructed in 30 models with innumerable optional accessories they cover every requirement for new and special yarns. They can produce elastomeric yarns for socks and stockings, elastomeric yarns for weaving, double rigid yarns in cotton, wool, nylon etc, and fa..

Stretch core yarns - construction and materials (French) (Les files continus a fil d'ame - construction et matieres)

There are many ways of producing stretch core yarns, such as air-jet or ring spinning methods. This article discusses the methods of construction for the foremost materials which are used to produce both hard core and soft core yarns, concentrating on the effects of different types of short polyester fibres when they are used to cover a p..

Analysis of yarn twist parameters (Russian)

A mathematical expression is derived for the twist factor of a yarn, the accuracy of which is greater than standard. It enables a different strategy to be adopted when designing testing instruments. The method also makes it possible to compare the twist intensities for yarns having different linear densities.

Indian cottons and influence of mech processing on nep generation

The number of neps in unginned cotton is quite small. During ginning and preliminary cleaning, neps increase significantly and as a result, cottons delivered to the mill contain neps in the range of 100 to 1000 per gram. Kluka et al have observed that yarn neps are primarily influenced by the number of neps in the raw material, regardless..

Suessen Compact Spinbox SC 1-M

The Suessen SC 1-M compact spinbox features a large trash trough fitted with the SweepCat oscillating device to avoid heavy fly contamination of the spinning machine. The SweepCat functions like a snow plough to remove the dirt extracted at the individual spinning positions and improve yarn quality, reduce end breaks, and provide greater ..

Spinner's Attraction at ITMA '99.

At ITMA 1999, Murata showed its Vortex spinning machines with four line drafting systems and vortex systems to impart twist. In Murata's modified Twin spinning machine, two slivers supplied to the draft unit pass through the spinning nozzles separately to facilitate two-for-one twisting. The DREF 2000 system by Fehrer manufactures both S-..
