BCF Carpet Yarn Spinning Machines.

Rieter's Rietex 10 Flex manufactures three color carpet yarn in a single-stage process with the same quality as a two state process. The Rietex 10 Flex offers productivity improvements of 30-50 percent. The patented arrangement of the intermingling and texturing units allows parallel procesing of individual colors, which combine in the fi..

Yarn Dyeing Machines.

Then maschinen-u. Apparatebau GmbH's Multiflex range of sample yarn dyeing machines perform dyeing processes that are transferrable to production facilities at a ratio of 1:1. A range of performance data (heating, dye bath ratio, rinse times, and rinse wa

Sewing thread production

This article looks at the production of sewing thread, it looks at assembly winding, finish application, singeing and finish winding, where the process chain and its machines ensure the quality of the end product. Twisted spun yarns are essential where single yarns no longer satisfy the requirements. Perfectly twisted yarns are characteri..

Properties of OE rotor and MJS yarns spun at high spinning speeds

The properties of OE rotor and MJS yarns spun from acrylic-cotton (70:30) blended fibres have been compared. Both OE rotor and MJS yarns could be spun with a wide range of spinning speeds without being adversely affected in their tenacity and breaking extension Spinning speed and ribbon width have been found to affect the abrasion resista..

Yarn quality for shuttleless weaving and knitting

Fabric quality requirement comrpises of two factors, fabric properties and fabric faults. Shuttleless looms are more sensitive to imperfections and hairiness of both warp and weft yarn, so in order to sustain the higher tension, due to higher speeds, better yarn strength and elongation, together with higher resistance to friction and fewe..

Properties of OE Rotor and MJS Yarns Spun at High Spinning Speeds

Researchers studied the properties of 70/30 acrylic/cotton yarns spun on open end rotor and air jet spinning machines. Researchers spun two sets of 29.5 tex yarns at selected speeds and evaluated them for tenacity and breaking extension (using an Instron tensile tester), yarn irregularity (using the Uster evenness test), flat abrasion res..

Measurement of Resilience Properties of Carpet Yarn.

Resiliency is typically measured in terms of carpets. This research project aims to develop a method for testing the resiliency of pile yarns. The method will test the quality of pile yarns after spinning and assist in the selection of pile yarns to manufacture carpets. Its ultimate goal is to develop new carpet yarns with improved resili..

Spliced Yarn Qualities.

Researchers studied the breaking strength and flexural rigidity of spliced yarn. As the level of the ends preparation air volume increased, the breaking strength of the spliced yarn increased, the bending stiffness decreased, and the bending hysteresis increased. Increasing the level of the ends retraction resulted in and increase in the ..

Yarn Hairiness Update.

A literature review of research concerning yarn hairiness since 1991 addresses instrumentation for measuring yarn hairiness; the effects of spinning processes on yarn hairiness, including ring spinning, rotor spinning, air jet spinning, DREF spinning, worsted spinning, Sirospinning, PLYfil spinning, core and wrap spinning systems, and nov..

Influence of Twisted Yarn and Fabric Structure on Cotton Crepe. Part 1: Measurement of Untwisting Torque of Cotton Yarn Dipped into Boiling Water.

An experiment analyzing the creping mechanism of cotton crepe fabrics measured the untwisting torque of twist set cotton yarns dipped into boiling water; evaluated the effects of twist number, yarn count, and number of multiple yarns on untwisting torque;
