A Direct Reading Spindle Speed Meter

1976-09-01T00:00:00Z

Title: A Direct Reading Spindle Speed Meter Authors: Kalyanaraman, A. R.; Sridhar, U. Abstract: A simple, inexpensive and direct-reading spindle speed meter has been designed and fabricated. The accuracy and reproducibility of measurements made with the meter are comparable to those obtained with the stroboscope. The potential industrial applications of the meter, besides its use in spindle speed measurement, are indicated. Page(s): 113-114

Estimation of Nitrogen Content of Resin Finished Fabrics by Infrared Spectroscopy

1976-09-01T00:00:00Z

Title: Estimation of Nitrogen Content of Resin Finished Fabrics by Infrared Spectroscopy Authors: Venkatesh, G. M.; McCall, E. R.; Tripp, V. W. Abstract: Migration of resin during drying has been found to affect the balance of crease recovery and useful wear life of resin finished fabrics. To understand the phenomenon of resin migration better, fabrics have been crosslinked with DMDHEU by different processes and their physical properties have been studied. In this study, an attempt has been made to characterize the resin finished fabrics from their infrared spectra. The relationships obtained suggest that the nitrogen content of resin finished fabrics can be estimated easily and accurately from their infrared absorption spectra. Page(s): 108-112

A Theoretical Study of Yarn Irregularity through the Spectrum

1976-09-01T00:00:00Z

Title: A Theoretical Study of Yarn Irregularity through the Spectrum Authors: Narasimham, T.; Ganesh, K.; Kothari, N. R. Abstract: Yarn irregularity may be thought of as the sum of three components: the periodic, the totally random and the quasiperiodic variations. A spectral decomposition of these components gives more information about yarn irregularity than the variances alone. Methods for such decomposition have been suggested. Examination of the spectra of some yarns has indicated considerations to be taken into account when proposing a model for the arrangement of fibres in yarns. Page(s): 104-107

Response of Cotton Fibres to Anticrease Chemical Finish-A Varietal Study by X-Ray Diffraction Method

1976-09-01T00:00:00Z

Title: Response of Cotton Fibres to Anticrease Chemical Finish-A Varietal Study by X-Ray Diffraction Method Authors: Pai, B. Tara; Panda, B. C. Abstract: A technique based on the principles of X-ray diffraction has been developed for assessing the response of cotton fibres to easy-care finish. The method is useful for varietal screening of cotton fibres. Out of 26 cotton samples tested by this method, the tensile strength of three samples (B-1007, SB-289 and SB-1085-6E) was found to increase as a result of treatment with an anticrease finishing chemical.
