Whitening (leather Processing)
The leather manufacturing process is divided into three sub-processes: preparatory stages, tanning and crusting. All true leathers will undergo these sub-processes. A further sub-process, surface coating may be added into the sequence. The list of operations that leathers undergo vary with the type of leather. Production management The leather making process is in general restricted to batch processing, but if the surface coating sub-process is added then some continuous processing can be included. The operation flow has to follow the preparatory → tanning → crusting → surface coating sub-process order without deviation, but some of the sub-processes can be omitted to make certain leathers (or partially tanned/ untanned products). Preparatory stages The preparatory stages are when the hide/skin is prepared for tanning. During the preparatory stages many of the unwanted raw skin components are removed. Many options for pretreatment of the skin exist. Not all of the options ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stuffing (leather Processing)
Stuffing, filling, or dressing is an edible mixture, often composed of herbs and a starch such as bread, used to fill a cavity in the preparation of another food item. Many foods may be stuffed, including poultry, seafood, and vegetables. As a cooking technique stuffing helps retain moisture, while the mixture itself serves to augment and absorb flavors during its preparation. Poultry stuffing often consists of breadcrumbs, onion, celery, spices, and herbs such as sage, combined with the giblets. Additions in the United Kingdom include dried fruits and nuts (such as apricots and flaked almonds), and chestnuts. History It is not known when stuffings were first used. The earliest documentary evidence is the Roman cookbook, Apicius ''De Re Coquinaria'', which contains recipes for stuffed chicken, dormouse, hare, and pig. Most of the stuffings described consist of vegetables, herbs and spices, nuts, and spelt (a cereal), and frequently contain chopped liver, brains, and other ...

Dyeing (leather Processing)
Dyeing is the application of dyes or pigments on textile materials such as fibers, yarns, and fabrics with the goal of achieving color with desired color fastness. Dyeing is normally done in a special solution containing dyes and particular chemical material. Dye molecules are fixed to the fiber by absorption, diffusion, or bonding with temperature and time being key controlling factors. The bond between dye molecule and fiber may be strong or weak, depending on the dye used. Dyeing and printing are different applications; in printing, color is applied to a localized area with desired patterns. In dyeing, it is applied to the entire textile. The primary source of dye, historically, has 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 washing and general use. Different classes of dyes are used for different types o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Shaving (leather Processing)
Shaving is the removal of hair, by using a razor or any other kind of bladed implement, to slice it down—to the level of the skin or otherwise. Shaving is most commonly practiced by men to remove their facial hair and by women to remove their leg and underarm hair. A man is called ''clean-shaven'' if he has had his beard entirely removed. Both men and women sometimes shave their chest hair, abdominal hair, leg hair, underarm hair, pubic hair, or any other body hair. Head shaving is much more common among men. It is often associated with religious practice, the armed forces, and some competitive sports such as swimming, running, and extreme sports. Historically, head shaving has also been used to humiliate, punish, for purification or to show submission to an authority. In more recent history, head shaving has been used in fund-raising efforts, particularly for cancer research organizations and charitable organizations which serve cancer patients. The shaving of head hair is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rehydrated
In physiology, dehydration is a lack of total body water, with an accompanying disruption of metabolic processes. It occurs when free water loss exceeds free water intake, usually due to exercise, disease, or high environmental temperature. Mild dehydration can also be caused by immersion diuresis, which may increase risk of decompression sickness in divers. Most people can tolerate a 3-4% decrease in total body water without difficulty or adverse health effects. A 5-8% decrease can cause fatigue and dizziness. Loss of over ten percent of total body water can cause physical and mental deterioration, accompanied by severe thirst. Death occurs at a loss of between fifteen and twenty-five percent of the body water.Ashcroft F, Life Without Water in Life at the Extremes. Berkeley and Los Angeles, 2000, 134-138. Mild dehydration is characterized by thirst and general discomfort and is usually resolved with oral rehydration. Dehydration can cause hypernatremia (high levels of sodium i ...
