Effect of the yarn on the effect of the yarn tension rod [bar] in warp knitting (German)

The technical and physical processes involved in the stitch-forming processes on warp-knittin machines are examined. Special attention is devoted to the effect of yarn properties on the yarn tension rod/bar. Yarn tension, take-up tension and yarn tension rod movement are measured for various yarns. Details are given of trials carried out ..

New techniques ensure yarn quality

The Fiber Distribution Center (FDC) and Fiber Research Center (FRC) of Parkdale Mills Inc. are both located in Belmont, USA. The FDC receives and tests all of the company's cotton which gives the benefit of supplying cotton with the same characteristics to multiple plants. The operation of the centre and examples of its innovation are des..

Effect of sewing condition on seam stiffness and softness (Japanese)

The effects of the mechanical properties of sewing thread and stitch length on seam stiffness and softness were investigated. Bleached sheetings were chosen as a sample assuming the seam and surface characteristics were obtained by the KES system, using s

Innovations keep novelty yarns moving ahead

The US novelty yarn market is 1996 ended on a bright note and good busines is anticipated in 1997. The market leader remains chenille yarns with boucles and loops, seeds, eyelashes and stretch yarns also in demand. The market views and product ranges for several US producers are presented including Yarn Mavens, Glen Raven Mills, Silk City..

Change in the properties of cotton and linen yarns during thermal ageing (Russian)

The effect of thermal ageing/heat treatment on the mechanical properties of cotton and linen yarns, is studied. Investigations in the temperature range 100-150℃ show that thermal ageing suddenly accelerates above 120℃, which is reflected in a sharp deterioration in the mechanical properties (tenacity, breaking elongation and work to rup..

Special yarn for use in surgical swabs

Courtaulds Speciality Fibres have developed an X-ray detectable yarn which is intended for use in surgical swabs. Micropake is a multifilament polypropylene yarn loaded with barium sulphate during melt spinning and wrapped with a fine polyester. The loading meets the X-ray opacity test requirements of the British Pharmacopeia. Micropake i..

On-Line Quality Control Engineering for Synthetic Yarn Spinning Mills and Texturing Companies

Online control systems for the spinning and texturing of synthetic yarns have aplications for friction texturing, air jet texturing, spin drawing texturing, and spin cable texturing. Systems recognize intolerable changes quickly, mark misproduction, and o

Special Yarn for Use in Surgical Swabs

Courtaulds Specialty Fibres developed an X-ray detectable yarn for manufacturing surgical swabs. The new Micropake multifilament polypropylene yarn is wrapped with a fine polyester fiber of 3,800 decitex. During melt extrusion, treatment of polypropylene with barium sulfate results in a yarn that meets X-ray opacity requirements. Micropak..
