Additional Physical Format: Online version: Application of vat dyes. Lowell, Mass.: The Association, (OCoLC) Document Type: Book: All Authors. The Identification of Vat Dyes on Cellulosic Materials focuses on the determination of the dyeing class of all the dyes usually found on cellulosic materials, which is a another method of distinguishing between reactive and other classes of dyes on these materials. This book discusses the characteristics of vat and soluble vat dyes. CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): N the s vat dyes, bearing about 60 1 C.I. Names (I), were available in the U.S. under about different trade names. This collection of dyes has not changed much in recent years. About 60% of them have C.I. Numbers-i.e., ihe chemical structure of the principle color component is known; 85 % are derivatives of.   Vat dyes are widely used for colouring cellulosic fibre, especially cotton fibre along with viscose rayon, leather and other fibres. Indigo dye is the most used vat dye as it becomes the base for dyeing denim fabrics.

  vat dyes are water insoluble pigment. So vatting is done for making it solubilized form. Its application inverts reduction to water soluble leuco compound, then dyeing is done& after that re-oxidation of leuco dye in the fibre to soluble pigments. There are basic 4 steps for vat dyeing.   (An eBook reader can be a software application for use on a computer such as Microsoft's free Reader application, or a book-sized computer that is used solely as a reading device such as Nuvomedia's Rocket eBook.) Users can purchase an eBook on diskette or CD, but the most popular method of getting an eBook is to purchase a downloadable file of. Disperse dyes are substantially water-insoluble nonionic dyes for application to synthetic hydrophobic fibers from aqueous dispersions. Disperse dyes are applied as very finely divided materials which are adsorbed onto the fibers with which they then form a solid solution. Dispersed dyes are primarily used for polyester and acetate fibers. Vat dyes can't be directly applied and required vatting because it is insoluble in water. But vat dyes fastness properties is good among the all dyes. The word "vat" means vessels. The dye takes their generic name from vatting.

Vat dyes are a class of dyes that are classified as such because of the method by which they are applied. Vat dyeing is a process that refers to dyeing that takes place in a bucket or vat. The original vat dye is indigo, once obtained only from plants but now often produced synthetically.   2.
