Tensile Properties and Fracture of Viscose Yarn Under High Speed Impact
نویسندگان
چکیده
In order to ensure an acceptable quality even at the highest spinning or weaving speeds, tensile instruments and testing conditions have to be improved. Therefore, a new high-speed dynamometer and a new method to subject yarns at strain rates similar to those found in current textile operations have been developed. This high-speed dynamometer has then been used to investigate the influence of high strain rates on tensile properties and fracture morphology of a technical viscose multifilament yarn.

A Study on Spinning Limits and Yarn Properties with Progressive Change in Yarn Count in Friction Spinning
The spinning limit for three different fibres (cotton, viscose rayon and polyester) on a Dref-3 friction spinning machine has been investigated. The change in yarn properties with progressive change in count has also been reported. The count range has been seen to be dependent on fibre type. As one progresses from very coarse to fine counts, the yarn tensile property remain fairly unaltered for...
متن کاملImpact of Elastane Addition on UV Protective Properties of Viscose and Polyacrylonitrile Knits.
Textiles can provide effective protection against UV radiation because they reflect, absorb and scatter solar wavelengths. Properly designed, they significantly increase the area of covered skin. The optimal combination of thickness, fabric density, mass per unit area, knitted structure, yarn type and yarn linear density, facilitate the production of textiles with high UV protection properties....
متن کاملDynamic and Quasi-Static Tensile Properties of Structural S400 Steel
The study of mechanical behavior of the structural steel S400 under quasi- static and dynamic loading has been the subject of this investigation. In oder to obtain different stress - triaxiality conditions the specimens were notched with 1, 1.5, 2 and 3.5 mm notch radius. The results of fractography show as the velocity of tension increases, ductility reduces and a ductile-brittle transition oc...

Friction stir spot welding (FSSW) is a type of solid state welding that is used in the connection of small pieces and light metals such as aluminum alloy especially. The technical problem during melting of aluminum alloys is one of the most important reasons for developing application of friction stir welding for aluminum alloys. In this research, the effects of important processing parameters ...
متن کاملMechanical Characterization of Glass-Basalt-Carbon/Polyester Hybrid Composites
Influence of the stacking sequences of hybrid composites on the tensile strength, flexural strength, inter-laminar shear strength (ILSS) and impact energy was investigated. The hybrid glass-basalt-carbon/polyester composite laminates were processed by hand lay-up procedure at room temperature. The fracture surface of the composite laminates after the tension and flexural test was examined by sc...
