A simple method to determine handle strength of bags

Sat, 01 Jun 1991 00:00:00 GMT

Title: A simple method to determine handle strength of bags Authors: Sathish, H S Abstract: A simple method to evaluate the handle strength of the bag is proposed. This fills the gap in the existing bag testing procedures in any international standards. The procedure determines the bag handle strength in terms of impact strength and velocity of lift.

Flexural stiffness and linear density of palmyra fibres

Sat, 01 Jun 1991 00:00:00 GMT

Title: Flexural stiffness and linear density of palmyra fibres Authors: Rajagopal, K B; Iyer, K R Krishna Abstract: Thirteen samples of palmyra fibres were tested for flexural stiffness using a simple experimental set-up. A parallel array of fibres was supported at the ends on a pair of knife-edges and loaded in the middle. The load applied and the depression produced at the midpoint were measured by dial gauges that formed parts of a fabric compressibility tester.The stiffness determined in this manner was found to have good correspondence with fibre linear density. This result has led to the conclusion that the trade practice of grading palmyra fibres according to linear density is adequate for a classification with respect to stiffness as well.

Title: Physico-chemical nature of barky jute treated with Penicillium corylophilum Dierckx Authors: Basak, M K; Bhaduri, S K; Sao, K P Abstract: The effect of softening treatment by the fungus, Penicillium corylophilum Dierckx on the chemical and physical nature of the barky jute has been discussed. A considerable amount of non-fibrous impurities in barky jute has been found to be diminished, resulting in improvement of fibre quality. Page(s): 175-177

Effect of mixing high-grade cotton at OE machine on quality of waste-spun yarn

Sat, 01 Jun 1991 00:00:00 GMT

Title: Effect of mixing high-grade cotton at OE machine on quality of waste-spun yarn Authors: Sundaram, R P Abstract: Cotton roving of longer length/high uniformity fibres was mixed in smaIl amount (9.25%) at OE machine with a waste sliver of short length/less uniformity fibres and it was found that this mixing technique helps to produce more even OE yarn without any noticeable increase in imperfection levels and strength.
