The report offers a list of key developments in the textile dyestuff market

The dyestuff scale trolley is completely closed and a slight vacuum is created during the weighing phase.

In developing country like India, dyestuff industries are growing rapidly and produce numerous types of dyes and pigments.

German chemists had been at the forefront of many important scientific discoveries, and industrialists had been quick to commercially exploit those developments to manufacture pharmaceuticals, synthetics and dyestuffs.

Towards the end of the 19th century Wardle, who owned a silk dyeing and printing company, became internationally acclaimed as an expert on India's wild silks and dyestuffs. He was also a Fellow of the Royal Society of Chemists, and a geologist, musician, composer, educator and sportsman (figure 1).

When the Ti[O.sub.2] electrodes cooled down to around 100[degrees]C, the electrodes were dipped in dye solutions, which included 0.5 mM N719 and different concentrations of dyestuff 4L in tert-butanol/acetonitrile (AN) (1: 1 in volume).

Over the years, China has emerged as the leading global manufacturer, trader, as well as consumer of dyestuffs. Gradually maturing production technology and presence of strong downstream customer base within the country have been propelling demand for pigments in the country over the recent years.

Because of the consumer restrictions and the legislations of countries that prohibit the addition of synthetic dyestuffs to animal rations and to human foods, the choice for the use of natural dyestuffs increases continuously.

60 if-then rules were created following the example: If thickness is low and roughness is middle and gloss is low and thread density is low and dyestuff concentration is very low then change of basic dyestuff concentration is middle.

According to Li, their excavation team found from the soil strata dating back 15,000 years, or the late Paleolithic Era, more than 20 pieces of hematite, one of iron oxides commonly used as a dyestuff.

Others need an acid or base to introduce them and provide a special kind of social lubricant--making the textile ready for the dyestuff. Sometimes a mordant is required.

The first such association was observed in 1895 (Rehn 1895), and subsequent research among dyestuff workers identified the aromatic amines benzidine and 2-naphthylamine as bladder carcinogens (Case et al.

The first aniline dyes were limited by the need to use a substance known as a mordant to fix the dye permanently to the textile fiber, a requirement that added an extra step to the dyeing process.[5,6] In 1883, an obscure young chemist named Paul Bottiger found a more direct method.[7] At the time of his discovery, Bottiger was working in the dyestuff chemical laboratory of the Friedrich Bayer Company in Elberfeld, Germany.

The Hong Kong dyestuff distributor and garment manufacturer listed on the Stock Exchange of Hong Kong will be renamed Softbank Investment International (Strategic) Ltd., it said.

Dyestuff manufacturers are to be directed to give a declaration on the label of their products stating whether the product contains any of the banned amines.
