SITRA microprocessor controlled high speed reeling machine

Considering the existing problems in the conventional reeling machines and in the reeling department into consideration, a sophisticated and cost effective high speed reeling machine has been designed and developed by SITRA. Sophisticated features like microprocessor controlled digital counter, simplified drive design, individual yarn sto..

Hollow cotton fibre yarn

Kurabo Industries and Kuray of Japan have developed a highly absorbent, quick drying, hollow cotton fibre yarn called Spin Air. The yarn draws moisture into a hollow space within itself so facilitating evaporation. It holds 1.2 times more liquid and absorbs and drys 1.3 times faster than existing types of cotton, making it suitable for to..

Wet Waxing Yarn and Fiber Treatment.

Wet waxing confers optimal properties on yarns or fibrs in preparation for further treatment. Researchers at Kugatextil GmbH tested 14 products for wet waxing from different manufacturers under production conditions. They tested the products for their effect on friction, fogging, abrasion resistance, staining, distribution of coating add-..

Extracting Geometrical Features from a Continuous-Filament Yarn by Image-Processing Techniques.

Research used image processing techniques to analyze the geometrical properties of the interstices between the filaments of a section of continuous filament polyester yarn. The technique used the concept of connection degree and fuzzy surface based on fuzzy theory to describe the uncertainty in the shape of each interstice. The technique ..

Reply to 'Comments on 'Interpretation of Single Fiber, Bundle and Yarn Tenacity Data."

A letter to the editor replies to comments on a paper published by Sasser et al. in the February 1991 issue of Textile Research Journal on the relationship between yarn strength and fiber strength. Sasser used data on yarn tenacity from a paper published by Ramey et al. in a 1977 issue of Textile Research Journal to derive the relationshi..

Twintex: Multi-Shaped Glass Reinforcements.

Vetrotex's Twintex rovings consist of continuous glass filaments and a thermoplastic material distributed homogeneously. Fiber contents vary from 20-65 percent. The roving converts easily into a finished composite via heating and pressing. The original Twintex roving was made with a polypropylene matrix. It now comes with a polyester matr..

Development of an Auto-Doffer for Covering Machines. Part 3: Yarn Draw-In Device Installed on Vehicle.

A mobile automatic doffing system improved the spandex drawing-in process. The system consisted of an automatic yarn draw-in apparatus capable of processing spandex in the upper and lower spindles simultaneously. The machine was mounted on a wheeled vehicle that ran in contact with the covering machine. Drawing-in operations used very fin..

The Effect of Testing Speed on the Hairiness of Ring-Spun and Sirospun Yarns.

A study examined the effect of testing speed on results obtained using yarn hairiness meters that report the number of hairs in different length groups. The S(3) values of ring spun and Sirospun yarns increased as testing speeds increased from 25 to 100 m
