Natural dye
Natural dyes are dyes or colorants derived from plants, invertebrates, or minerals. The majority of natural dyes are vegetable dyes from plant sources—roots, berries, bark, leaves, and wood—and other biological sources such as fungi and lichens. Archaeologists have found evidence of textile dyeing dating back to the Neolithic period. In China, dyeing with plants, barks and insects has been traced back more than 5,000 years. The essential process of dyeing changed little over time. Typically, the dye material is put in a pot of water and then the textiles to be dyed are added to the pot, which is heated and stirred until the color is transferred.
Wet processing engineering
Wet Processing Engineering is one of the major streams in textile engineering refers to textile chemicals process engineering and applied science. The other three streams in textile engineering are yarn engineering, fabric engineering and apparel engineering. Wet process is usually done on the manufactured assembly of interlacing fibers, filaments, and/or yarns having substantial surface (planar) area in relation to its thickness, and adequate mechanical strength to give it a cohesive structure. In other words, wet process is done on manufactured fabric. The processes of this stream is involved or carried out in aqueous stage and thus it is called wet process which usually covers pretreatment, dyeing, printing and finishing.
Hair coloring
Hair coloring, or hair dyeing, is the practice of changing the hair color. The main reasons for this are cosmetic: to cover gray or white hair, to change to a color regarded as more fashionable or desirable, to restore the original hair color after it has been discolored by hairdressing processes or sun bleaching. Hair coloring can be done professionally by a hairdresser or independently at home. Today, hair coloring is very popular, with 75% of women and 18% of men living in Copenhagen having reported using hair dye according to a study by the University of Copenhagen. At home coloring in the United States reached $1.9 billion in 2011 and is expected to raise to $2.2 billion by 2016.
List of unidentified murder victims in the United States
Of the thousands of people murdered every year in the United States, some remain unidentified. Many victims are not identified for years or even decades after they were killed—as in the case of Tammy Jo Alexander, who was murdered in 1979 and remained unidentified until 2015. Including both murder victims and those who died of other causes, about 40,000 bodies remain unidentified in the United States. The body of a white female aged thirty-four to thirty-eight was found in Slaughter Creek, near the Sipsey River in Romulus, Tuscaloosa County, Alabama on April 18, 1982. The victim had been beaten, strangled and sexually assaulted.
Oriental rug
An oriental rug is a heavy textile, made for a wide variety of utilitarian and symbolic purpose, produced in “Oriental countries” for home use, local sale, and export. Oriental carpets can be pile woven or flat woven without pile, using various materials such as silk, wool, and cotton. Examples range in size from pillow to large, room-sized carpets, and include carrier bags, floor coverings, decorations for animals, Islamic prayer rugs ("sajjadah"), Jewish Torah ark covers ("parochet"), and Christian altar covers. Since the High Middle Ages, oriental rugs have been an integral part of their cultures of origin, as well as of the European and, later on, the North American culture.
Blond
Blond (male), blonde (female), or fair hair, is a hair color characterized by low levels of the dark pigment eumelanin. The resultant visible hue depends on various factors, but always has some sort of yellowish color. The color can be from the very pale blond (caused by a patchy, scarce distribution of pigment) to reddish "strawberry" blond or golden-brownish ("sandy") blond colors (the latter with more eumelanin). On the Fischer–Saller scale, blond color ranges from A (light blond) to O (dark blond). The word "blond" is first documented in English in 1481 and derives from Old French "blund, blont", meaning "a colour midway between golden and light chestnut".
Dyeing
Dyeing is the process of adding color to textile products like fibers, yarns, and fabrics. Dyeing is normally done in a special solution containing dyes and particular chemical material. After dyeing, dye molecules have uncut chemical bond with fiber molecules. The temperature and time controlling are two key factors in dyeing. There are mainly two classes of dye, natural and man-made. The primary source of dye, historically, has generally been nature, with the dyes being extracted from animals or plants. Since the mid-19th century, however, humans have produced artificial dyes to achieve a broader range of colors and to render the dyes more stable to resist washing and general use.
