False twist crimping machine for crimping synthetic yarns

The threading-up over the curved heater plate in a false-twisting texturing machine is assisted by an intermediate yarn path on the lid over the heater plate. IPC D02G D02J.

The hairiness of cotton yarns

Fifty years ago, yarn hairiness was regarded as almost a curious yarn property that sometimes was capable of interfering with textile processes and of producing trouble during weaving and knitting. In the decade of the 1950s, this curious property was converted into a measurable yarn parameter. For the authors work comprehensive investiga..

Universal Covering Machine for New Knit Yarns.

Hamel AG and Santoni collaborated on the Hamel Elasto Twister LE covering machine that processes filament, staple fiber, and blend yarns. The balloonless covering system uses lwo yarn tension to yield high volume covered yarns with excellent uniformity. The Elasto Twister features a 1 kilogram spindle, a delivery speed of 80 meters per mi..

Hamel: Single Covering Machine for Filament Sector.

Hamel AG's Elasto Twister LE balloonless single covering machine for filament yarns requires 45 percent less energy consumption than other balloonless spindle machines. The machine manufactures uniform elastic ply yarns, microfiber yarns, high bulk yarns, and other materials without covering defects or soiling. It achieves spindle speeds ..

Yarn Faults and Package Defects -- Part I.

Yarn defects reduce fabric quality and grade, delay deliveries, and increase costs and waste. Spinner's double defects involve double thickness in the yarn and result from two roving yarns simultaneously entering the drafting system during ring spinning, fiber strands from the front roll commingling with adjacent ends at the ring bobbin, ..

Effect of Extension Rate and Cyclic Loading on Some Physical Properties of Viscose.

Researchers determined the effects of extension rate and cyclic loading on the physical properties of rayon yarns. A Saurer 60 B loom manufactured plain lining fabrics from rayon warp and filling yarns. A Statimat tensile testing machine under an extension rate of up to 9,999 millimeters per minute determined tenacity, elongation, work to..

Engineered Yarn Manufacturing in the New Millennium.

Engineered yarns are manufactured to achieve a specific Uster percentage, defect level, or other properties with minimal variation for specific end uses. To manufacture engineered yarn quality rather than increase average yarn quality. The Juran Trilogy method for minimizing quality variation involves quality planning, quality, and improv..

The Effect of Chenile Yarn Properties on the Performance of Chenille Upholstery Fabrics.

The manufacture of chenille yarns involves feeding an effect yarn to a core yarn and twisting. The machine controls yarn count, twist, and texture. High quality chenille requires electronic clearing to eliminate missing pile. Chenille yarns manufactured from acrylic, viscose, and cotton fibres are the most common in upholstery fabrics. Fi..

KoSa Introduced Three New Yarns: Antimicrobial, Stretch-aire, and Accepta.

KoSa manufactures Imbue, Stretch-aire, and Accepta yarns at its Shelby, North Carolina, facility. Imbue has antimicrobial properties to protect the yarn. An innovative process embeds a ceramic silver based additive into the polyester yarn. It is suitable for high performance and fashion apparel, home furnishings, medical supplies, hospita..

Fibrillated Lyocell Filament Yarns in Textile Substrates.

A study used fibrillated lyocell filament yarns with different levels of microhairiness to manufacture finished circular knit fabrics and compared their properties with those of fabrics knit using conventional nonfibrillated cellulosic filament yarns. Fabrics made from fibrillated lyocell filament yarns had a softer hand and more volumino..
