YARN ATTRITION BY ABRASION--COMPARISON BETWEEN SPUN YARNS FROM POLYESTER/COTTON BLENDS OBTAINED BY MEANS OF DIFFERENT SPINNING PROCESSES

The use of two Zweigle yarn testers, the G565 Hairiness Meter and the G555 Staff Tester, allowed the clarification of some aspects of hairiness in ring spun, rotor spun, and friction spun polyester/cotton yarns, including yarn attrition and loss of matter through yarn self-rubbing. These phenomena were influenced by blend composition, the..

LENGTH METERING UNIT -- RETROFIT KIT FOR WINDING MACHINES

Electrotex's Metrotex length metering unit can be retrofitted on winders without an electrical trigger. The retrofit winder is then capable of producing precision, length-metered yarn spools. Each rotation of the drum generates an electrical pulse in the sensor, which is summed by the Metrotex. The thread monitor terminates summing when a..

TREATMENT TO IMPROVE WET ABRASION RESISTANCE.

Allied has patented a treatment that improves the wet abrasion resistance of yarns and cords. The process involves applying an aqueous over-finish that is based on a mixture of two compounds. Ideally, the yarns to be treated should be polyester, polyamide, or polyolefin yarns. The treatment is applied to yarns used for marine applications..

MCCOY-ELLISON--MACNATENSE YARN TENSIONING DEVICE

McCoy-Ellison's Magnatense yarn Tensioning device is used specifically for fiberglass, industrial, and heavy denier yarns. Tension is added to the yarn by an adjustable electromagnetic field, which is controlled by a central unit with up to six individual zones. The Magnatense comes in two tension ranges:5 to 35 grams and 10 to 130 grams...

WORLDWIDE MANUFACTURED FIBER PRODUCING CAPACITY.

Two tables and five graphs present trade data, by geographic area, on worldwide production of synthetic (non-cellulosic) fiber, polyester yarn/staple, acrylic staple, and artificial (cellulosic) fiber/yarn/staple for the period 1975 to 1992 (projected). The tables and graphs are derived from information published in June editions of Fiber..

SIZING METHODS FOR REDUCING YARN HAIRINESS

The ability of three sizing methods to reduce yarn hairiness was studied. Conventional sizing, sizing with separate end drying, and sizing with reduced end density using two sow-boxes were compared. The effect of sizing adhesives on yarn hairiness was also considered. A Zweigle Model G 565 hairiness meter was used to obtain quantitative m..

Characteristics of flat warp-spun yarns (Polish)

The wrap spinning of acrylic/polyester yarns is studied and the process is recorded on film. the structure and properties of the yarns are investigated.
