Colored fabrics

Benzoyl peroxide is a potent contact sensitizer in experimental studies, and this adverse effect may occur in up to 1% of acne patients. Care should be taken to avoid contact with the eyes and mucous membranes. Benzoyl peroxide is an oxidant and may rarely cause bleaching of the hair or colored fabrics.

Heavy-Duty Liquid Detergents. The ease of incorporation and affinity of FWAs are crucial in such formulations. Heavy-duty liquid detergents can also be employed as prespotters that are applied in concentrated form to heavily soiled areas before the normal washing process. Bright spots can be formed, especially on colored fabrics, due to washing out of the color they are intensified by the fluorescence of the locally high FWA concentration. For this reason, FWAs have been developed which cause less pronounced spotting that cannot be seen. The main products in use are 10 and 21 [143],... 

For the cream-colored fabric, coating with Parylene-C resulted in both increased initial modulus and an increased breaking-load. However, no increase in the strain-to-break was observed. This was found to be the case for both 1 and 5 )Im coating thicknesses. 

Dampen the stains with a 5% solution of potassium permanganate. Allow to set for a few minutes and then apply a 10% solution of sodium bisulfite. Care should be taken with colored fabrics, as the area may become bleached. Test on an out-of-the-way area, such as a shirttail. 

It is difficult if not impossible to determine when mankind first systematically applied color to a textile substrate. The first colored fabrics were probably nonwoven felts painted in imitation of animal skins. The first dyeings were probably actually little more than stains from the juice of berries. Ancient Greek writers described painted fabrics worn by the tribes of Asia Minor. But just where did the ancient craft have its origins Was there one original birthplace or were there a number of simultaneous beginnings around the world ... 

Perspiration tests similarly indicated the presence of two dyestuffs. In the alkali solution, the yellow color seemed to be removed almost completely, leaving a pink-colored fabric. In the acidic solution, the yellow dye migrated to the wool, silk, and nylon sections of the multifiber test strips, staining these fibers a bright yellow shade. The pink color seemed to bleed minimally a small amount of color was transferred in the alkali solution tests, but generally this pink color remained comparatively very fast. 

Color is a problem for scientific study. One aspect is the vocabulary one used to describe color. Mint green, bottle green, and Kelly green are nice names but not of great utility in that people s physical perception of color is not always the same. In some industries, such as colored fabric manufacture, current use is to send a set of standard colors which are matched by the producer. This is similar to the use of the Munsell color charts in geology. None of these processes makes use of physical optical spectral studies. The reason is that they are difficult to obtain and interpret. For a geologist, color is very important but we rarely have the possibility to standardize the method of our color perception. One reason is that color is both a reflective and transmission phenomenon. The thickness of the sample is critical to any transmission characteristics. Hence, a field color determination is different from one... 

They must not alter the shade of colored fabrics. 

Plants have been used not only to create paints, but also to create dyes to color fabrics and other items. Native Americans, Europeans, and early American pioneers all used plants to dye skins, fabric, wool, and thread for sewing. Although mixing and matching plants could create every color of the rainbow, some colors were easier to create than others. Browns, reds, and yellows were more common because many plants, when boiled, will turn these shades. But purples and blues.

Other additives to polymers make them colorful and beautiful. Just think about the stunningly colorful fabrics that are made from polymers, or the colorful kitchen utensils, house paints, and so on. A world without polymers Hard to imagine ... 

Dyeing, union n. A method of dyeing a fabric containing two or more fibers or yarns to the same shade so as to achieve the appearance of a solid colored fabric. 

Color care benefits are one example of added benefit. Fading of dark colors, particularly black or blue, has been achieved by use of a chlorine scavenger such as amine and its salts. Chlorine use by many municipal water systems to disinfect water causes a slow fading that is highly noticeable on dark color fabrics. Reduction in transfer of dyes from one fabric to another was claimed to be reduced by use of polyvinylpyrrolidone and poly (4 vinylpyridine A-oxide) in fabric conditioners...
