2009/4/15
This study deals with the effect of cross-sectional shape of yarn duct of interlacer on the performance of interlaced yarn and aims at finding the interlacers with better performance. The performance...
Interlacing Process of Multiple Filament Yarn
Interlacing process Interlaced yarn Interlacer Yarn motion Airflow
2009/4/15
In interlacing process, a multiple filament yarn, which runs in an air jet device called an interlacer, is hit by high-speed air jet and then, tangling parts and opening parts are made alternatively...
Yarn Path on a Mold for Double Sheet Bend Knotter
Double sheet bend Mold Yarn path Dowker notation
2009/4/13
Knot strength is very important in processing ropes than other textile products. Thus double sheet bends are usually used in rope mills, because their knots are small and strong in order to tie two ...
Designing Yarn Path on a Mold for Knot Formation
Knot Mold Path Knot theory Dowker notation
2009/4/13
Making knot is important work in the textile industry. Now, devices which make knots such as knotters and splicers are spread. However these devices cannot make all knots used in the textile industry...
Geometry Effect of Air Suction Gun on the Yarn Suction Characteristics
Suction gun Geometry effect Yarn suction force Yarn suction efficiency
2009/4/9
We experimentally discussed the effects of airflow geometries in an air suction gun on the suction characteristics of running yarn. Geometry parameters focused on were 1) compressed-air inflow angle ...

In this work, 0.133 - 0.166 tex and 38 mm of fiber length of polyester and viscose rovings of 591 tex (αtex 8) were blended variously (polyester/viscose 35/65%; polyester/viscose 50/50%; polyester/vis...
Periodic and Chaotic Motion in Sirofil Yarn Spinning
two-strand spinning Sirospun Sirofil chaotic motion.
2009/2/17
A dynamic model is established for two-strand yarn processing. The oscillating frequencies
of Sirofil spinning in vertical and horizontal directions are approximately obtained. The
stability and cha...
