Influence of Weave and Weft Characteristics on Tensile Properties of Fabrics
woven fabrics breaking strength breaking elongation weave weft characteristics
2009/2/17
The breaking strength and elongation at break of a fabric firstly depend on the breaking
strength and elongation at break in the testing direction of the used yarn. In our research
not only the infl...
Study on Pneumatic Weft Insertion Behavior in Main Nozzle
weft insertions unsteady flow pull force main nozzle testing
2009/2/16
In this paper, with the aim of analysis, the main nozzle was divided into four part (tubes). This allowed to analyse detailed airflow parameters of each tube, and introduce a method of experiment to t...
A Technology of Soft Weft-Knitted Fabrics Manufactured from a Fibre Stream
jersey knitted fabrics soft knitted fabrics fluffy knitted fabrics fibre stream roving
2009/2/13
Extraordinary soft and fluffy knitted products may be obtained by a technology of weft-knitt-ed fabrics which we have developed and manufactured with the use of circular open-top-knitting machines. Th...
Effects of Warp-Weft Density Variation and Fabric Porosity of the Cotton Fabrics on their Colour in Reactive Dyeing
weft-warp density porosity reactive dyeing
2009/2/13
One of the main problems in dyehouses is caused by the differences between the structural parameters of the reference fabric of which the dyeing recipe is known and the fabric to be dyed. In such a ca...
Pneumatic Loom for Leno Weaves with Rotary Mechanism Forming the Shed and Beat-up of the Weft
weaving loom leno weave shed forming mechanism weft beat-up mechanism
2009/2/11
We present herein a genuinely new concept for a rotary mechanism for pneumatic looms, which forms the shed and beating-up the weft, together with an electromagnetic device to drive the guide needle ba...
Using Electromagnetic Force in Weft Insertion of a Loom
weft insertion mechanism projectile loom electromagnetic field and force
2009/2/9
Weft insertion in weaving is an important subject, which has been studied by many research workers, for decades. A number of mechanisms have been invented, designed, manufactured, developed and employ...
Velocity Control of Weft Insertion on Air Jet Looms by Fuzzy Logic
fuzzy logic jet yarn count linear density
2009/2/7
In this study, a weft insertion system in air jet weaving looms was controlled by using fuzzy logic. The effects of yarn properties on weft yarn velocity along the tube have been investigated.The effe...
The Pneumatic Transport of Weak Weft Structures
weft picking pneumatic picking weak weft structures weft degradation
2009/2/7
This article presents research work which concerns the loss of weft continuity while being picked with the use of a pneumatic loom. A stand designed and constructed with the aim of investigating the d...
Infl uence of Yarn Count and Warp and Weft Thread Density on Colour Values of Woven Surface
fabric simulation yarn count threads density
2009/2/7
Prior to the introduction of numerical evaluation of colours and equipment to measure their values optically, it was impossible to objectively estimate colour deviations resulting
from changed yarn c...
Weft Take-up Distribution Over the Width of Woven Fabrics Manufactured with the Use of Jet Looms

Assessment of Knitting Conditions at States of Discontinuous Robbing Back in the Knitting Zone on Weft-knitting Machines
knitting process knitting zone robbing back effect raising cam dynamic forces
2009/1/20
On the basis of a deterministic digital model of the knitting process, loop formation conditions were identified at the states of discontinuous robbing back in the knitting zone. A linear cam of desce...
