London Shrunk
The London shrunk, or London shrinkage, process was an 18th-century textile finishing process designed to preshrink wool fabrics and minimize their tendency to shrink before being used for making garments. When compared to the traditional steam shrinking method of controlling shrinkage, London shrinkage provided more permanent results in terms of reducing the likelihood of fabric shrinkage. London shrunk was found to be effective for fine worsteds, it was not typically used for woolens. The term London shrunk originated from London's garment industry. The practice of London shrinking was alternatively known as sponging. Shrinkage resistance and preshrink Preshrinking is a process in which fabric is intentionally shrunk before it is cut and sewn into a garment or other textile product. Manufacturers use the term " pre-shrunk" to describe fabric or garments that have undergone processing, which is expected to limit shrinkage to less than 3% in either direction during standard ...

Finishing (textiles)
In textile manufacturing, finishing refers to the processes that convert the woven or knitted cloth into a usable material and more specifically to any process performed after dyeing the yarn or fabric to improve the look, performance, or "hand" (feel) of the finish textile or clothing. The precise meaning depends on context. Fabric after leaving the loom or knitting machine is not readily useable. Called greige cloth at this stage, it contains natural and added impurities. Sometimes it is also processed at fiber or yarn stages of textile manufacturing. Grey fiber or yarn or fabric goes through a series of processes such as wet processing and finishing. Finishing is a broad range of physical and chemical treatments that complete one stage of textile manufacturing and may prepare for the next step, making the product more receptive to the next stage of manufacturing. Finishing adds value to the product and makes it more attractive, useful, and functional for the end-u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wool
Wool is the textile fiber obtained from sheep and other mammals, especially goats, rabbits, and camelids. The term may also refer to inorganic materials, such as mineral wool and glass wool, that have some properties similar to animal wool. As an animal fiber, wool consists of protein together with a small percentage of lipids. This makes it chemically quite distinct from cotton and other plant fibers, which are mainly cellulose. Characteristics Wool is produced by follicles which are small cells located in the skin. These follicles are located in the upper layer of the skin called the epidermis and push down into the second skin layer called the dermis as the wool fibers grow. Follicles can be classed as either primary or secondary follicles. Primary follicles produce three types of fiber: kemp, medullated fibers, and true wool fibers. Secondary follicles only produce true wool fibers. Medullated fibers share nearly identical characteristics to hair and are long but ...

Textile
Textile is an Hyponymy and hypernymy, umbrella term that includes various Fiber, fiber-based materials, including fibers, yarns, Staple (textiles)#Filament fiber, filaments, Thread (yarn), threads, and different types of #Fabric, fabric. At first, the word "textiles" only referred to woven fabrics. However, weaving is not the only manufacturing method, and many other methods were later developed to form textile structures based on their intended use. Knitting and Nonwoven, non-woven are other popular types of fabric manufacturing. In the contemporary world, textiles satisfy the material needs for versatile applications, from simple daily clothing to Bulletproof vest, bulletproof jackets, spacesuits, and Medical gown, doctor's gowns. Textiles are divided into two groups: consumer textiles for domestic purposes and technical textiles. In consumer textiles, Aesthetics (textile), aesthetics and Textile performance#Comfort, comfort are the most important factors, while in techn ...

Dimensional Stability (fabric)
Dimensional stability (in fabric) pertains to a fabric's ability to maintain its initial size and shape even after undergoing wear and care, which is a desirable property. Textile manufacturing is based on the conversion of fiber into yarn, yarn into fabric, includes spinning, weaving, or knitting, etc. The fabric passes through many inevitable changes and mechanical forces during this journey. When the products are immersed in water, the water acts as a relaxing medium, and all stresses and strains are relaxed and the fabric tries to come back to its original state. The more dimensionally stable a fabric is, the less it is subject to shrinkage. Shrinkage is the change of dimensions in textile products when they are washed or relaxed. The change is always expressed relative to the dimensions before the exposure of washing or relaxing. Shrinkage is also called residual shrinkage and measured in percentage. The major cause of shrinkage is the release of stresses and strains introd ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Worsted
Worsted ( or ) is a high-quality type of wool yarn, the fabric made from this yarn, and a yarn weight category. The name derives from Worstead (from Old English ''Wurðestede'', "enclosure place"), a village in the English county of Norfolk. That village, together with North Walsham and Aylsham, formed a manufacturing centre for yarn and cloth in the 12th century, when pasture enclosure and liming rendered the East Anglian soil too rich for the older agrarian sheep breeds. In the same period, many weavers from the County of Flanders moved to Norfolk. "Worsted" yarns/fabrics are distinct from woollens (though both are made from sheep's wool): the former is considered stronger, finer, smoother, and harder than the latter. Worsted was made from the long-staple pasture wool from sheep breeds such as Teeswaters, Old Leicester Longwool and Romney Marsh. Pasture wool was not carded; instead it was washed, gilled and combed (using heated long-tooth metal combs), oiled and finall ...

Woolen
Woolen (American English) or woollen (Commonwealth English) is a type of yarn made from carded wool. Woolen yarn is soft, light, stretchy, and full of air. It is thus a good insulator, and makes a good knitting yarn. Woolen yarn is in contrast to worsted yarn, in which the fibers are combed to lie parallel rather than carded, producing a hard, strong yarn. Commercial manufacture The woolen and worsted process both require that the wool (and other similar animal fibres, cashmere, camel, etc.) be cleaned before mechanical processing. Woolen and worsted nomenclatures apply only to the textile processing of animal fibres, but it has become common to include fibre blends under these terms. The resultant fabrics will be classified as being either woolen or worsted, but this designation is assigned during fiber processing and yarn formation, not in the cloth or finished garment. A woven woolen fabric is one which is subjected to fabric finishing techniques designed to add a dir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ironing
Ironing is the use of an iron (appliance), iron, usually heated, to remove wrinkles and unwanted creases from fabric. The heating is commonly done to a temperature of , depending on the fabric. Ironing works by loosening the bonds between the long-chain polymer molecules in the fibres of the material. While the molecules are hot, the fibres are straightened by the weight of the iron, and they hold their new shape as they cool. Some fabrics, such as cotton, require the addition of water to loosen the intermolecular bonds. Many synthetic polymer, modern fabrics (developed in or after the mid-twentieth century) are advertised as needing little or no ironing. Permanent press clothing was developed to reduce the ironing necessary by combining Wrinkle-resistant fabric, wrinkle-resistant polyester with cotton. The first known use of heated metal to "iron" clothes is known to have occurred in China. The electric iron was invented in 1882, by Henry W. Seely. Seely patented his "electric fl ...

Calendering (textiles)
Calendering of textiles is a finishing process used to smooth, coat, or thin a material. With textiles, fabric is passed between calender rollers at high temperatures and pressures. Calendering is used on fabrics such as moire to produce its watered effect and also on cambric and some types of sateens. In preparation for calendering, the fabric is folded lengthwise with the front side, or face, inside, and stitched together along the edges. The fabric can be folded together at full width, however this is done less often as it is more difficult. The fabric is then run through rollers at high temperatures and pressure that polish the surface and make the fabric smoother and more lustrous. Fabrics that go through the calendering process feel thin, glossy and papery. The wash durability of a calendered finish on thermoplastic fibers like polyester is higher than on cellulose fibers such as cotton, though each depends on the amount and type of finishing additives used and the machine ...

Compaction (textiles)
Compaction (compacting) is a finishing process used to minimize shrinking in textiles. Textile products that are loosely woven or knitted shrink more, whereas tightly knitted and woven products are more stable. The structure of knitted fabrics is competitively loose and flexible. Compaction, like sanforization for woven fabric, is intended to reduce shrinkage in tube and open width Knitted textiles. Compactor A compactor is a textile finishing machine that is specifically designed for compaction. Compaction has a mechanism that shrinks the fabric forcibly in order to render it shrinkproof, preventing any residual shrinking in the applied fabric. The machine has two cylinders, the delivery cylinder moves faster than the take-off cylinder. Shrinkage in textiles is an undesirable property caused by fiber properties, fabric structure and elongations caused during prior treatments. Components A compactor machine is equipped with an entry, small tenter frame, steaming unit and a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stenter
A stenter (sometimes called a tenter) is a machine used in textile finishing. It serves multiple purposes, including heat setting, drying, and applying various chemical treatments. This may be achieved through the use of certain attachments such as padding or coating. The machine works by holding the fabric's edges while it is fed from rollers, allowing it to advance gradually while maintaining its dimensions. Eventually, the stretched sheet is pulled off at a specific speed by a second set of rollers. At the delivery end, the edges are released by the stenter pins or clamps that were holding it. The earlier non-mechanized equivalent was the tenter frame. Etymology and history Stenter is derived from "tenter", which has its origins in the Latin word , meaning "to stretch", passing through an intermediate French stage. The primary purpose of this machine is to stretch and dry fabric. In the past, frames used for this purpose were called "tenter", and the metal hooks emplo ...

Textile Manufacturing By Pre-industrial Methods
Textile manufacturing is one of the oldest human activities. The oldest known textiles date back to about 5000 B.C. In order to make textiles, the first requirement is a source of fibre from which a yarn can be made, primarily by spinning. The yarn is processed by knitting or weaving to create cloth. The machine used for weaving is the loom. Cloth is finished by what are described as wet process to become fabric. The fabric may be dyed, printed or decorated by embroidering with coloured yarns. The three main types of fibres are natural vegetable fibres, animal protein fibres and artificial fibres. Natural vegetable fibres include cotton, linen, jute and hemp. Animal protein fibres include wool and silk. Man-made fibres (made by industrial processes) including nylon, polyester will be used in some hobbies and handicrafts and in the developed world. Almost all commercial textiles are produced by industrial methods. Textiles are still produced by pre-industrial process ...
