the srrc no-twist yarn system

this citation summarizes a one-page announcement of technology available for utilization. a method for producing a no-twist cotton yarn directly from card web has been developed. in a production system a card web will be divided into approximately 20 strips with each strip being processed into a yarn by its own separate no-twist component..

die physikalisch-technologischen eigenschaften von geweben in abhaengigkeit von der struktur der eingesetzten oe-rotorgarne. t. 1 vergleich von geweben aus verschiedenartig hergestellten baumwollgarnen (the physico-technical properties of textiles dependi

knowledge of the interaction between the yarn spinning process and the resulting textile is a precondition for using new spun yarns. the aim of the investigations was therefore to determine the characteristics and physical-technical properties of 3 yarns produced by different techniques. these are oe spun yarns, non-twisted spun yarn and ..

Tension of unwinding thread

A reserch study has been carried out into the changes in tension that occur as a yarn is unwound from a cheese which can effect efficiencies in rewinding, wapring and weft insertion. Yarn was unwound from different cheeses at a speed of 400 m/min. and the tension variations recorded using a very sensitive tensometer. The effect on the ten..

Long-staple fibre spinning line (German)

Details are given of a long-stable spinning line which comprises a faller set drafting unit, a wool combing machine, a speed frame and a ring spinning machine, together with automated units. In the worsted sector great demands are placed on machine flexibility, especially in the case of small lots. The technical and economic advantages of..

A study on thermal insulation property of wool/polyester blending wadding (Chinese)

The compressing property and the thermal insulation property of different composite rate wool/polyester blending wadding were tested. The analysed results show the blending wadding's thermal insulation property is a little larger than that of the pure wool wadding. From this aspect, wool.polyester blending wadding can be produced to take ..

Process for producing splittable elastane yarns

In a dry spinning process for producing an elastane multifilament yarn, in which an elastane solution is dry-spun to form the yarn, the improvement comprises reducing or preventing interfilamentary adhesion by: using at least one multihole spinning jet whose individual capillaries are located on one plate, whereby the distance between the..

Mitsubishi Rayon Develops chitosan containing acrylic staple fiber

Japanese company, Mitsubishi Rayon, has developed an acrylic staple fibre which incorporates ultrafine particles of chitosan. The chitosan is kneaded into the acrylic fibre so does not become dislodgedduring finishing processes. This gives the fibre a good antibacterial property which is retained after fifty washings. Hand and dyeability ..

Studies on handle of microdenier polyester filament dress materials

Polyester filament fabrics made from microdenier and normal denier yarn are compared for their low stress mechanical properties and hand values. Effects of twisting and sizing on microdenier filament fabric are studied. Sizing proves to be the most important process for microdenier multifilament yarn to realise its speciality effect in th..

Teflon fibre. The technical textile industry has found a fibre suitable for its needs (Italian) (Le fibre Teflon. Il tessile tecnico ha trovato una fibra idonea ai suoi bisogni)

Teflon fibres are produced by DuPont. They are based on polytetrafluoroethyle and have a wide range of uses. The article presents a brief history of the developoment of Teflon fibres and describes their applications. They are used in filters for high temperature gas, maintenance-free bearings, filters for liquids, protective clothing, sew..

Electromagnetic interference shielding

A circular warp-knit gasket for shielding against electromagnetic interference is described in this article. The gasket consists of a knitted core of synthetic monofilament covered by a circular warp-knitted sheath, the sheath is sufficiently conductive to provide protection from a wide range of frequencies. In addition the shielding has ..
