Cotton waste reclamation: a money-spinning process

The reuse of waste discarded in the processing of cotton is considered. The total waste separated from cleaners and cards is estimated to have a fibre content of 65-70％. Machines from Trutzschler GmbH and Co. of Monchengladbach, Germany, for the processing of cleaning and carding wastes and gin motes are described. Cost aspects of reclam..

Influence of reworkable waste on yarn quality

A preliminary study dealing with the effects of reworkable waste on yarn tenacity is presented. Yarn was produced on the Uster Quickspin system. Samples without reworkable waste and with a blend of different types and amounts of waste were made for comparison. Including reworkable waste in a bale mix lay down may have a detrimental effect..

Improving the bulk of worsted yarns. I. A basic bulking method

A basic method for increasing the bulk of worsted yarns is described, in which air jet false-twisters are employed. A technique for measuring yarn diameter is introduced and the results of the bulking treatment are assessed.

Experiences in polyester texturing with short heater

A statistical test design was run in order to determine sensitive process parameters for the false-twist texturing of continuous filament polyester on short heater machines. Using 167 dtex, 36 filament and 76 dtex, 36 filament Diolen yarn, the effect on yarn elongation, tenacity, hot air shrinkage and crimp was studied with respect to the..

A comparison of the properties of cotton-covered cotton/polyester yarns and fabrics representing ring, friction, and tandem spinning technologies

Four cotton covered cotton/polyester yarns were produced using both filaments and staple polyester fibers in the core. Three different spinning systems (ring, friction, and tandem spinning processes) were used to produce the cotton covered yarns. for co

Centenary for Glass Fibre Innovator.

In 1931, Schuller GmbH developed the Schuller Vertical Draw Process for the manufacture of glass tubes and rods, which led to the manufacture of glass fibers in 1936. Its Schuller Drawn Rod Drum Process for glass fibers manufacture was patented in 1938 a

Influence of Reworkable Waste on Yarn Quality

Reworkable textile waste consists of three classifications: dirty (card flats, blowroom waste, and ginning waste), clean (sliver, noil, and pneumafil), and hard (twisted roving, yarn, and fabrics). Before utilization, some reworkable wastes require clean

Bobbin drying by air and radio frequency

Systems for dyring yarn after dyeing, developed by the Italian firm of Obem Dyeing Machinery, are described. Particular attention is devoted to the ERF/0/10 dryer which combines radio frequency with warm air circulation. The ERF/0/10 produces energy savings, ensures a uniform temperature throughout the bobbin, dries at low temperature, re..

Fibre cutting apparatus

The apparatus claimed comprises a rotor carrying parallel blades on which the fibre is wound. As well as being rotated, the rotor is reciprocated axially to discharge the cut fibre in cooperation with further rotors which rotate with first rotor, but do not reciprocate. Cut fibres from behind the blendes are ejected into a discharge space..
