Title: Effects of picking periods and average mass of seed on fibre properties of MCU-5 cotton
Authors: Selvan, M Tamil; Raghunathan, K
Abstract: The
effects of picking periods and average mass of seed on fibre properties have
been studied using MCU-5 Indian cotton variety, collected from three different
locations at various picking periods. It is observed that there is a
significant impact due to the average mass of seed in a particular picking
period on fibre quality. In general, the mass of seed plays a vital role in
deciding the quality of fibres.

Title: Influence of critical ring frame parameters on the minimum twist of cohesion in yarns
Authors: Gokarneshan, N; Ghosh, Anindya; Anbumani, N; Subramaniam, V
Abstract: An
instrument has been designed to measure the minimum twist of cohesion (MTC) of
ring-spun yarn. The influence of spindle speed, traveller mass, and twist
multiplier on the MTC has been studied using three-factor Box and Behnken
factorial design. A very high coefficient of determination between the
experimental values and the calculated values is obtained from the response-surface
equation. The selected factors have significant contribution in determining the
fibre cohesion in yarn. The optimum value of MTC is observed at higher level of
spindle speed, traveller mass, and twist multiplier within the experimental zone
explored. Spindle speed has the greatest influence on MTC, followed by twist
multiplier and the traveller mass with the current experimental set-up.

Title: Dimensional stabilization of cotton plain knitted fabric by using ultrasonic waves
Authors: Mohamadi, V; Jeddi, Ali AA
Abstract: Cotton
knitted fabric with plain structure has been subjected to relaxation treatment
using mechanical energy of ultrasonic waves to reach the maximum shrinkage. It
is observed that this method of relaxation has more effectiveness on the
fabric's dimensional parameter than the conventional relaxation method.

Title: Flexural properties of rice straw reinforced polyester composites
Authors: Prasad, A V Ratna; Rao, K Murali Mohan; Kumar, M Anil; Rao, K Mohan
Abstract: Rice straw fibres have been extracted and
incorporated in polyester resin matrix to prepare rice straw rein forced polyester
composites and the flexural properties of resultant composites studied. The
composites with a mean flexural strength of 66.3 Mpa, which is greater than
that of plain polyester (55.08 MPa), can be formulated with an optimum fibre volume
of about 40%. The flexural modulus or composite is found to be 2630 MPa which
is about 1.5 times greater than that of plain polyester. The specific flexural
modulus is nearly 2 times greater than that of polyester resin. Straw-based composites
are suitable as core material for structural board products.
