Pigment for Textile, Stationery and Others

Pigment extraction from fungus for textile dyeing

The present study is an attempt to isolate and optimize the fermentation conditions of three fungus, namely Trichoderma virens, Alternaria alternata and Curvularia lunata to get pigments for the purpose of textile dyeing. Highest optical density has been achieved in potato dextrose broth at 28oC in 25 days under static conditions. Wool and silk are dyed unmordanted with very good wash and rub f...

Stationery for medical records: 1912-21.

Sir, In his letter (March Journal, p.127) Dr Kopelowitz states that as far as he can ascertain, the state made no arrangements whatsoever for providing stationery for recording medical notes before 1921. In fact a form was agreed in 1912 'following the model of an ordinary day book "such as doctors keep in connection with their private patients" '.I These forms were found to be unsatisfactory a...

Mechanical Color Reading of Wood-Staining Fungal Pigment Textile Dyes: An Alternative Method for Determining Colorfastness

Colorfastness to washing and crocking (color loss due to rubbing) are essential qualities for any dye/fabric combination that will be used for garments or upholstery. In this study, colorfastness to washing and crocking of fabrics dyed with wood-staining fungal pigments was compared to colorfastness of commercial dyes using an alternative mechanical testing method. Overall, wood-staining fungal...
