The book starts with an introduction  comprise a literature review on the enzymes  (history, source, structure .etc.) as well as their  application in textile industry. The experimental  work comprise two chapters: in the first Laccase  enzyme formulation has been used in discharge  printing of cotton fabrics dyed with different  reactive dyes and the effect of enzyme  concentration, pH of the printing paste, enzymatic  treatment time and temperature as  well as the viscosity of the printing paste on the  colour discharge were studied to obtain the optimum  conditions. In the second the suitability of  locally available brewer''s yeast as a  biodischarging agent in textile printing was  thoroughly investigated. The different factors  affecting white discharge printing of cotton  fabrics coloured with different reactive dyes were  investigated . Successfully results were obtained  on using Laccase enzyme or brewer''s yeast as a  biodischarging agent instead of unecofriendly  reducing agents.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783838352961\"\u003e\u003ch3\u003eBiodischarge Printing\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783838352961","offer_id":39469161185373,"sku":"9783838352961","price":49.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/6fadc38d-d27a-4389-8437-e7b89212e273.jpg?v=1773382163","url":"https:\/\/shop.autorenwelt.de\/products\/utilization-of-enzymes-in-textile-discharge-printing-von-heba-el-hennawi-und-i-abd-el-thalouth","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
