Reducing Pigmented Fibres in White Wool
The presence of dark fibres in white wool results in reduced profits or in cost recovery claims by wool processors and in reduced confidence in wool as an apparel fibre, which ultimately means lower prices for greasy wool. The allowances set by fabric manufacturers for contaminants are extremely small, typically no more than 3 contaminant faults per garment or per running metre of fabric, while...
متن کاملAutomatic Dark Fibres Detection in Wool Tops
Is proposed a method for the automatic detection of dark fibres in wool tops based on image processing. A software which implements this method was developed, composed by five modules: KL projection, light correction, Gabor filtering, segmentation and morphology. The digital image are taken by a camera placed in a balanced illumination system. The method was calibrated and tested on 170 images ...
متن کاملDynamic Modulus of Chokla Wool Fibres by Sonic Pulse Method
The dynamic moduli of white and canary coloured Chokla wool fibres and their alkaline thioglycollate-reduced fibres were determined with a sonic pulse of 5kHz. The dynamic modulus of fibres decreased significantly on reduction. the decrease being more in canary coloured fibres. This modulus explains more satisfactorily the role of disulphide bonds for low strains than the stress-strain characte...
متن کاملCarotenoids as food colourants.
INTRODUCTION Carotenoids are one of the most important groups of natural pigments. It has been estimated that nature produces about 100 million tons of these pigments per year. They give brilliant yellow and red colours to many fruits, vegetables, roots, flowers and autumn leaves; they produce the colour of the egg yolk, of many algae, yeasts and mushrooms, Crustaceae as well as of the feathers...
متن کاملChanges in Fibre Curvature during the Processing of Wool and Alpaca Fibres and Their Blends
This paper studied the wool and alpaca fibre curvature and its variation during the fibre processing. It revealed the effect of wool fibre crimp on the cohesion properties of alpaca and wool blended slivers. Different wool and alpaca tops were blended via a number of gillings, and the role of wool fibre curvature in alpaca/wool blend processing has also been investigated. During the wool fibre ...
