    Disperse dyes were originally developed for the dyeing of cellulose acetateand are water insoluble. The wool fiber at this stage is known as top. In package dyeing yarns that have been wound on perforated spools are dyed in a pressurized tank. Previously, in order to remove the size, textiles were treated with acid, alkali or oxidising agents, or soaked in water for several days so that naturally occurring microorganisms could break down the starch.

    Enzymes give the manufacturer a newer, easier set of tools to create new looks. This is achieved by treating a fiber with both diazoic and coupling components. Dyeing is normally done in a special solution containing dyes and particular chemical material. The gassed yarn is darker in shade afterwards, but should not be scorched.

    This process is typically used when different colored yarns are used in the construction of fabrics e. Drawing frame: Draws the strand out Slubbing Frame: adds twist, and winds onto bobbins Intermediate Frames: are used to repeat the slubbing process to produce a finer yarn. In the traditional stonewashing process, the blue denim was faded by the abrasive action of pumice stones on the garment surface. The cotton leaves the carding machine in the form of a sliver: a large rope of fibres.

The fabric passes over brushes to raise the fibers, then passes over a plate heated by gas flames. Cross dyed fabrics may be mistaken Textile Processing with Enzymes book fiber or yarn dyed materials as the fabric is not a solid color, a characteristic considered typical of piece dyed fabrics.

Commercial cotton is priced by quality, and that broadly relates to the average length of the staple and the variety of the plant.

The dye penetration is excellent in fiber dyeing, therefore the amount of dye used to dye at this stage Textile Processing with Enzymes book also higher. The husks and meal are processed into animal feed, and the stems into paper.

Samanta, Santanu Basak and S. Enzyme accelerates the reaction An enzyme accelerates the rate of particular reaction by lowering the activation energy of reaction The enzyme remains intact at the end of reaction by acting as catalyst 2. With the use of catalase, the reducing agent can be eliminated or the amount of rinse water can be dramatically reduced, resulting in less polluted wastewater or lower water consumption.

The fifth chapter offers important insights in process engineering and describes major problems of industrial applications of enzymes in textiles.

Enzymes work in milder conditions Every specific enzyme has a specific temperature and pH value in which they perform their best in speeding the chemical reaction but any temperature or pH beyond the specified one would only degrade the enzymes performance.

This method is not suitable for apparel with many components such as lining, zippers, and sewing thread, as each component may dye differently.

Enzymes used in textile processing - photo from Novozymes It represented great progress, therefore, when crude enzyme extracts in the form of malt extract, or later, in the form of pancreas extract, were first used to carry out desizing.

Textile manufacturing

The carding machine consists mainly of one big roller with smaller ones surrounding it. When dyed, the wool yarns Textile Processing with Enzymes book dyed blue, whereas the polyester yarns remain white. It covers all the relevant aspects of textile processing with enzymes, from the chemical constitution and properties of textile materials as potential substrates for enzymes, to the processing of these materials; from Textile Processing with Enzymes book biochemistry and enzymology to the industrial application of these biocatalysts.

Volume one is the first step in this roadmap series and discusses sustainable eco-friendly raw materials, technologies, and processing methods in the textile and clothing sector.

Another scouring chemical is detergent which is an emulsifying agent and removes dust and dirt particles from the fabric.

Today, highly alkaline chemicals caustic soda are used for scouring. Furthermore, using these hazardous chemicals result in high COD chemical oxygen demandBOD biological oxygen demand and TDS, in the waste water Recently a new enzymatic scouring process know as 'Bio-Scouring' is used in textile wet-processing with which all non-cellulosic components from native cotton are completely or partially removed.

The decision regarding the selection of colors has to be made early in the manufacturing process. It is also easily adapted for artificial fibres. Top dyeing is preferred for worsted wools as the dye does not have to be wasted on the short fibers that are removed during the combing process.

Textile processing with enzymes aims to provide the textile technologist with an understanding of enzymes and their use with textile materials and in process engineering. The enzymes most commonly involved in textile applications are hydrolases and oxidoreductases.

Enzyme and Its Applications in Textile Processing Enzyme: Enzymes are protein catalysts produced by living cells that catalyze specific chemical or biochemical reactions.

Due to this, and in order to reduce alkali content in the effluent, Bio-scouring is introduced in the scouring process in which biological agent is used, such as and enzyme. This is the main motivation of this roadmap series on sustainable textiles and clothing.Textiles BIOTOUCH ® and ECOSTONE ®.
