tailieunhanh - UPF of cotton fabrics printed with arecanut slurry

The present study was undertaken to investigate the efficiency of natural printed fabric on UV protection. Arecanut slurry was powdered; sodium alginate and kokilaksha seed gums were used for the printing process. Optimization of printing recipe was done using 3 different ratios of dye sources with combination of sodium alginate and kokilaksha seed gums. Screen printed samples were assessed for visual acceptance and colourfastness properties. Samples printed without mordant and with FeSO4 mordant using gum concentration exhibited higher acceptance (WMS) with respect to depth of colour, evenness, sharpness and overall appearance. Based on outcome of the study basic portion and printed portion of cotton fabric were assessed by UPF, UVA, UVB ratings. Samples printed with pure arecanut slurry exhibited highest blockage (UVA: , UVB: ) compared to other samples. Samples printed with 75:25 arecanut:myrobolan combination exhibited good protection than the 50:50 arecanut:myrobolan printed sample. | 2019 8 2 2258-2264 EXCELLENT PUBLISHERS International Journal of Current Microbiology and Applied Sciences ISSN 2319-7706 Volume 8 Number 02 2019 Journal homepage http Original Research Article https UPF of Cotton Fabrics Printed with Arecanut Slurry Deepa S.

Introduction The sun-blocking properties of a textile are enhanced when a dye pigment delustrant or ultraviolet absorber finish is present that absorbs ultraviolet radiation and blocks its transmission through a fabric to the skin. For this reason dyed fabrics provide better sun protection than bleached fabrics. Since naturally-coloured cottons contain .
