Changes of Sliver Irregularity in
A theoretical calculation is made to simulate the effect of drafting upon the sliver irregularity in two-zone drafting of three-over-three roller system. Two types of slivers, i.e., random sliver and optional sliver are considered. The effects of sliver count, staple fiber length, fineness of fiber, draft distribution between two drafting zones, maximal moving distance and distribution type of ...
متن کاملInternal Model Control of Textile Sliver Drafting Process
The paper is focused on modelling and control of an important textile engineering process: the textile sliver drafting process. This process plays a crucial role in textile production chain because low irregularity of drafted sliver is essential for production of high quality yarn. It is shown that this process can be modelled as a nonlinear time delay system with distributed delays. This model...
متن کاملTime Delay Systems Applications in Textile Industry – Modelling of Sliver Drafting Process
Abstract: The paper deals with an important textile engineering process: the textile sliver drafting process. It is shown that this process can be modelled as a non-linear time delay system with distributed delays. To convert it into a form more suitable for control purposes, this model is linearized and distributed delays are converted into equivalent lumped delay system. An easy to apply meth...
متن کاملsynthesis of platinum nanostructures in two phase system
چکیده پلاتین، فلزی نجیب، پایدار و گران قیمت با خاصیت کاتالیزوری زیاد است که کاربرد های صنعتی فراوانی دارد. کمپلکس های پلاتین(ii) به عنوان دارو های ضد سرطان شناخته شدند و در شیمی درمانی بیماران سرطانی کاربرد دارند. خاصیت کاتالیزوری و عملکرد گزینشی پلاتین مستقیماً به اندازه و- شکل ماده ی پلاتینی بستگی دارد. بعضی از نانو ذرات فلزی در سطح مشترک مایع- مایع سنتز شده اند، اما نانو ساختار های پلاتین ب...
Effects of Changes in Front Drafting Rollers Geometry on the Properties of Ring Spun Yarns
Regarding the importance of ring spinning method among spinning systems, great potentials exist for research about on the improvement of the quality and properties of ring spun yarn. This study aims to improve yarn quality by changing the shape and dimensions of spinning triangle through forming a groove in the middle zone of the front darfting 
roller with a curvature of 5 to 7 mm. For the ...
