Winch Dyeing Machine
A Winch machine or winch dyeing machine is a type of dyeing machine suitable for piece dyeing. A winch is a simple machine. It is equipped with a winch to guide the fabric from the vat. It has a straight front and a curved back. Long lengths are pulled over the winch and sewn together to form an endless rope. The winch dyeing machine allows fabric ropes pulled from the front and dropping back into the dye liquor. The winch or beck dyeing machine is one of the oldest forms. Principle and parameters Winch machine is a high liquor dyeing machine operating at 1:20 (MLR) and a maximum temperature of 98 degrees Celsius. In a winch dyeing, the fabric remains in movement while the dye liquor stays stationary similar to a jigger but with lesser stress on the materials. Hence, suitable for delicate textures and fabric types such as knitted fabrics. Chemicals and dyes dosed in the front portion that travels and get mixed in the entire vat. According to the size of the machine many number ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Machine
A machine is a physical system using Power (physics), power to apply Force, forces and control Motion, movement to perform an action. The term is commonly applied to artificial devices, such as those employing engines or motors, but also to natural biological macromolecules, such as molecular machines. Machines can be driven by Animal power, animals and Human power, people, by natural forces such as Wind power, wind and Water power, water, and by Chemical energy, chemical, Thermal energy, thermal, or electricity, electrical power, and include a system of mechanism (engineering), mechanisms that shape the actuator input to achieve a specific application of output forces and movement. They can also include computers and sensors that monitor performance and plan movement, often called mechanical systems. Renaissance natural philosophers identified six simple machines which were the elementary devices that put a load into motion, and calculated the ratio of output force to input fo ...

Dyeing
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Knitted Fabric
Knitted fabric is a textile that results from knitting, the process of inter-looping of yarns or inter-meshing of loops. Its properties are distinct from woven fabric in that it is more flexible and can be more readily constructed into smaller pieces, making it ideal for socks and hats. Weft-knit and warp-knit fabric There are two basic varieties of knit fabric: weft-knit and warp-knit fabric. Warp-knitted fabrics such as tricot and milanese are resistant to runs, and are commonly used in lingerie. Weft-knit fabrics are easier to make and more common. When cut, they will unravel (run) unless repaired. Warp-knit fabrics are resistant to runs and relatively easy to sew. Raschel lace—the most common type of machine made lace—is a warp knit fabric but using many more guide-bars (12+) than the usual machines which mostly have three or four bars. (14+) Structure of knitted fabrics Courses and wales In weaving, threads are always straight, running parallel either length ...

Chemical Substance
A chemical substance is a form of matter having constant chemical composition and characteristic properties. Some references add that chemical substance cannot be separated into its constituent elements by physical separation methods, i.e., without breaking chemical bonds. Chemical substances can be simple substances (substances consisting of a single chemical element), chemical compounds, or alloys. Chemical substances are often called 'pure' to set them apart from mixtures. A common example of a chemical substance is pure water; it has the same properties and the same ratio of hydrogen to oxygen whether it is isolated from a river or made in a laboratory. Other chemical substances commonly encountered in pure form are diamond (carbon), gold, table salt (sodium chloride) and refined sugar (sucrose). However, in practice, no substance is entirely pure, and chemical purity is specified according to the intended use of the chemical. Chemical substances exist as solids, liquids, ...

Batch Dyeing
Batch dyeing (exhaust dyeing) is a method of dyeing a textile material. The method involves the gradual transfer of dye from a dye bath to the textile material in the same piece of equipment. The various methods of batch dyeing result from the type of machine used in the dyeing process. Common machinery used in the batch dyeing process include the jigger dyeing machine, winch dyeing machine, jet dyeing machine and beam dyeing machine. Principles The principle of batch dyeing is the migration of dye molecules from the dye solution into the piece of fabric. This is done until the fabric reaches full exhaustion, all within the same 'batch'. The time taken as well as the depth of colour achieved in the batch dyeing process is dependent upon the different control factors of the process. These influencing factors are typically the temperature of the dye liquor, the specific liquor ratio and the method of agitation used. The specific liquor ratio is the ratio between the weight of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Color Of Clothing
Clothing color (color of clothing) is an essential aspect of the aesthetic properties of clothing. The color of clothing has a significant impact on one's appearance. Our clothes communicate about us and reveal our social and economic standing. Significance Color is a visual characteristic that is described by terms like red, orange, yellow, green, blue, purple etc. Typically, it is the color of an object that attracts the most attention. Color is one of the primary properties that is noticed when a consumer makes a decision to buy a dress. The colors are distinctive and distinguishable; we frequently refer to clothing by its color, for instance, a "blue shirt." Self decoration Decoration of self is prevalent in societies, and self-decoration is a fundamental characteristic of humans. Decorative values of clothing are regarded as "primary if not the most primary." Hence, as a decorative element, color plays a critical part in meeting the necessary criterion. Aesthetic co ...

Cold Pad Batch
Cold pad batch (CPB) is a method of dyeing textiles, typically cellulosic fibers such as cotton, in which the textile is impregnated with dye in a cold state, rather than being heated. High dye fixation and no thermal energy are the advantages of the Cold Pad Batch (CPB) process. CPB-dyed fabrics are less expensive, have a softer hand feel, and have a cleaner surface than exhaust dyed materials. The process may take up to 12 hours in the batching process, depending on the depth of the shade. The disadvantage is that batching is a time-consuming and lengthy process. The process was developed in 1960. During the dyeing process, the dye must become close and even with the material in order to produce a uniform color that is fast to moisture, heat, and light. Reactive dyes are currently the most common type of dye for cotton dyeing. Due to their superior fastness properties and simple application, reactive dyes are favored for cotton. The CPB technique uses less water and energy. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Textile Machinery
Textile Manufacturing or Textile Engineering is a major industry. It is largely based on the conversion of fibre into yarn, then yarn into fabric. These are then dyed or printed, fabricated into cloth which is then converted into useful goods such as clothing, household items, upholstery and various industrial products. Different types of fibres are used to produce yarn. Cotton remains the most widely used and common natural fiber making up 90% of all-natural fibers used in the textile industry. People often use cotton clothing and accessories because of comfort, not limited to different weathers. There are many variable processes available at the spinning and fabric-forming stages coupled with the complexities of the finishing and colouration processes to the production of a wide range of products. History Textile manufacturing in the modern era is an evolved form of the art and craft industries. Until the 18th and 19th centuries, the textile industry was a household work. ...
