ABSTRACT --— - The report describes a computer program developed for the design and simulation of a multistage hyperfiltration system for renovation of textile waste- water The program is capable of practical design, parametric simulation, and cost proiection of the multistage hyperfiltration system with tapered innerstages.
Textile industries are water intensive and vast amounts of water are used throughout textile manufacturing processes. Almost all dyes and chemicals are applied to the textiles in water baths. The preparation steps, such as desizing, scouring, bleaching, and. High-temperature hyperfiltration and ultrafiltration are being evaluated for recycle of both water and chemicals with operating manufacturing processes: (1) an atmospheric dye beck, (2) a pressure beck, (3) an open-width preparation range, (4) a dye range, and (5) a rope preparation by: 4.
preparing sodium hypochlorite by chlorinating a solution of caustic soda. Varying concentrations of this solution have found a multitude of applications so that the general public is now well acquainted with the material. This handbook will discuss sodium hypochlorite solutions.
Sodium hypochlorite solutions have attained widespread use in. Textiles and Textile Technology Fibre Blend Fibre blending is a common method to produce new textile materials by combining properties of individual fibre components together.
There are many fibre blends available in the market. Some examples are cotton – polyester, nylon – File Size: 3MB. Abstract of the Disclosure A process and apparatus is disclosed for treating textile desizing effluent so as to provide effective pollution abatement, and to render feasible the recovery of sizing material from the effluent for reuse as well as the conditioning of the effluent so that it Author: Curtis C.

Various Enzymes Used in Textile Processing: Amylases: Which convert amylose or amylopectin polymers, commonly referred to as starch in to water soluble shorter chain sugars (Starch desizing) Pectinases: Which hydrolyse pectins consisting of linear polymers of galacturonic acid (bio-scouring replacing caustic) Lipases: Which hydrolyse fats and oils into alcohol and organic acids.
Application of ozone in several domains of textile finishing has been reported. These include reduction clearing of polyester dyed with disperse dyes , discharge printing of reactive-dyed.

A Concise Guide On Textile Dyes, Pigments And Dye Intermediates With Textile Printing Technology by Dr. Panda, ISBN:Rs. / US$. Textile wastewater contains dyes mixed with various contaminants at a variety of ranges. Therefore, environmental legislation commonly obligates textile factories to treat these effluents before.
Potassium permanganate is a powerful oxidizing agent which has been used in garment washing indigo-dyed denim to produce a worn, faded appearance. It has also found some use in discharge printing of indigo. It is no longer favored by industry because of environmental concerns. It is quite hazardous, and can be caustic to skin.

In the textile industry, trichloroethylene has been used as a carrier solvent for spotting fluids and as a solvent in dyeing and finishing (Fishbein, ; Linak et al., ; Mertens, ). The main use of trichloroethylene in the textile industry is to clean cotton, wool and other fabrics.
