An example of a tie-dyed T-shirt A video about how to tie-dye. Tie-dye is a term used to describe a number of resist dyeing techniques and the resulting dyed products of these processes. The process of tie-dye typically consists of folding, twisting, pleating, or crumpling fabric or a garment, before binding with string or rubber bands ...
Resist techniques include screen printing, tie-dye, ikat, and batik. [39] royal purple Tyrian purple or royal purple is a purple-red dye which is extracted from several genera of sea snails, primarily Murex brandaris the spiny dye-murex (currently known as Bolinus brandaris). Murex dye was greatly prized in antiquity because it did not fade ...
The low water solubility is the basis of the good wash-fastness of these dyed fabrics. These dyes have good all-around colour fastness except to chlorine bleaches. Because the dye is water-insoluble, it will not bleed when washed in water and will not stain other clothes. The dye, however, may have poor fastness to rubbing.
Colour fastness is a term—used in the dyeing of textile materials—that characterizes a material's colour's resistance to fading or running.Colour fastness is the property of dyes and it is directly proportional to the binding force between photochromic dye and the fibre.
Process analysis initially involved sampling the variety of process streams or webs and transporting samples to quality control or central analytical service laboratories. Time delays for analytical results due to sample transport and analytical preparation steps negated the value of many chemical analyses for purposes other than product release.
In vivo staining (also called vital staining or intravital staining) is the process of dyeing living tissues. By causing certain cells or structures to take on contrasting colours, their form or position within a cell or tissue can be readily seen and studied. The usual purpose is to reveal cytological details that might otherwise not be ...
Dye penetrant inspection (DP), also called liquid penetrate inspection (LPI) or penetrant testing (PT), is a widely applied and low-cost inspection method used to check surface-breaking defects in all non-porous materials (metals, plastics, or ceramics).
Textile testing is the process of evaluating the quality and properties of a textile material through a series of tests at various stages of manufacturing. [1] Textile testing, like textiles, is a vast subject.
