Luster (textiles)
In textiles, lustre or luster is a physical property that makes them appear bright, glossy, and shiny. The amount of light reflected from the surface of a fiber is referred to as its luster.The level of luster is determined by how light reflects off the surface. For example, round surfaced fiber reflects more light and appears shinier than fiber with an irregular surface. Synthetic fibers with a more regular surface seem brighter than natural fibers with an irregular surface, with the exception of silk, which has a regular surface. Objective Luster is the degree of gloss or sheen possessed by the fiber or textile surface. Luster adds aesthetic values in fabrics, contributes to their attractiveness. Occasionally, this adds value to their quality assessment. In some cases, when lustre is undesirable, fibres are purposefully dulled by the addition of substances. Factors Factors affecting ''lustre (the way light reflects)'' lie with fiber properties, but various processes can a ...

Silk Yarn (3538527583)
Silk is a natural fiber, natural protein fiber, some forms of which can be weaving, woven into textiles. The protein fiber of silk is composed mainly of fibroin and is produced by certain insect larvae to form cocoon (silk), cocoons. The best-known silk is obtained from the cocoons of the larvae of the mulberry silkworm ''Bombyx mori'' reared in captivity (sericulture). The shimmering appearance of silk is due to the triangular Prism (optics), prism-like structure of the silk fibre, which allows silk cloth to refract incoming light at different angles, thus producing different colors. Silk is produced by several insects; but, generally, only the silk of moth caterpillars has been used for textile manufacturing. There has been some research into other types of silk, which differ at the molecular level. Silk is mainly produced by the larvae of insects undergoing holometabolism, complete metamorphosis, but some insects, such as webspinners and Gryllacrididae, raspy crickets, pr ...

Fiber
Fiber or fibre (from la, fibra, links=no) is a natural or artificial substance that is significantly longer than it is wide. Fibers are often used in the manufacture of other materials. The strongest engineering materials often incorporate fibers, for example carbon fiber and ultra-high-molecular-weight polyethylene. Synthetic fibers can often be produced very cheaply and in large amounts compared to natural fibers, but for clothing natural fibers can give some benefits, such as comfort, over their synthetic counterparts. Natural fibers Natural fibers develop or occur in the fiber shape, and include those produced by plants, animals, and geological processes. They can be classified according to their origin: *Vegetable fibers are generally based on arrangements of cellulose, often with lignin: examples include cotton, hemp, jute, flax, abaca, piña, ramie, sisal, bagasse, and banana. Plant fibers are employed in the manufacture of paper and textile (cloth), and die ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Shearing (textiles)
Shearing is a kind of mechanical finish in which the appearance of the fabric is enhanced by cutting the loops or raised surface to a uniform and even height. The machine may have a spiral blade similar to a grass cutting machine. A Shearing machine can cut the loop or the pile to a desired level. Shearing was most commonly used to make woolens and worsted materials. It was a part of dry finishing of woolen and worsted goods. Previously, shearing was also a component of gigging or napping; when partially produced goods were exposed to shear in order to improve the impact of gigging or napping, the process was referred to as "cropping." History Most of the Medieval clothing and textiles were processed and finished manually. The finishing of English Woolens includes shearing. Shearmen were skilled artisans who used to shear the fabric by hand. Shearman's job was to nap the cloth manually, using teasels and shears to trim the pile. A silky and smooth feeling was produced by the gra ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Draping
Drapery is a general word referring to cloths or textiles (Old French , from Late Latin ). It may refer to cloth used for decorative purposes – such as around windows – or to the trade of retailing cloth, originally mostly for clothing, formerly conducted by drapers. Drape Drape (draping or fabric drape) is the property of different textile materials how they fold, fall, or hang over a three-dimensional body. Draping depends upon the fiber characteristics and the flexibility, looseness, and softness of the material. Draped garments follow the form of the human body beneath them. Art In art history, drapery refers to any cloth or textile depicted, which is usually clothing. The schematic depiction of the folds and woven patterns of loose-hanging clothing on the human form, with ancient prototypes, was reimagined as an adjunct to the female form by Greek vase-painters and sculptors of the earliest fifth century and has remained a major source of stylistic formulas ...

Hand Feel
Hand feel (Hand, Fabric hand, Fabric feel) is the property of fabrics related to the touch that expresses sensory comfort. It refers to the way fabrics feel against the skin or in the hand and conveys information about the cloth's softness and smoothness. Hand feel is an estimated and subjective property of different fabrics, but nowadays, hand feel could be measured and assessed statistically. Tactile senses Our daily life experiences are profoundly influenced by the sense of touch. Touch is the first sense to develop, beginning in the first trimester of pregnancy. During the next few months in the womb, the baby's entire body develops touch receptors. Around 7 weeks into pregnancy, touch is the first sense to develop in the fetus. Therefore, hand feel is an important characteristic of clothing that provides sensory comfort. Hand feel (also called handle or drape) is one of the basic characteristics that are necessary for sensory comfort that is related to tactile comfort. It ...

Delustrant
A delustrant is a substance that reduces the lustre (sheen) of synthetic fibres. The most common delustrant is anatase titanium dioxide. Synthetic fibres such as nylon are normally extremely shiny and transparent when extruded. Adding powdered titanium dioxide causes the surface of the fibres to be rougher, reducing the sheen; at the same time, being opaque, it reduces the transparency of the fibre. To be effective as a delustrant, titanium dioxide must be powdered 0.1-1.0 µm, depending on the size of the fibre, and varying amounts (up to about 2%) can be used depending on the level of lustre required. Some of the words used to describe different lustre levels are: clear, bright, semi-dull, semi-matt, dull, matt, extra dull, and super dull.

Satin
A satin weave is a type of fabric weave that produces a characteristically glossy, smooth or lustrous material, typically with a glossy top surface and a dull back. It is one of three fundamental types of textile weaves alongside plain weave and twill weave. The satin weave is characterised by four or more fill or weft yarns floating over a warp yarn, and four warp yarns floating over a single weft yarn. Floats are missed interfacings, for example where the warp yarn lies on top of the weft in a warp-faced satin. These floats explain the high lustre and even sheen, as unlike in other weaves, light is not scattered as much when hitting the fibres, resulting in a stronger reflection. Satin is usually a warp-faced weaving technique in which warp yarns are "floated" over weft yarns, although there are also weft-faced satins. If a fabric is formed with a satin weave using filament fibres such as silk, polyester or nylon, the corresponding fabric is termed a 'satin', although some ...

Cotton
Cotton is a soft, fluffy staple fiber that grows in a boll, or protective case, around the seeds of the cotton plants of the genus ''Gossypium'' in the mallow family Malvaceae. The fiber is almost pure cellulose, and can contain minor percentages of waxes, fats, pectins, and water. Under natural conditions, the cotton bolls will increase the dispersal of the seeds. The plant is a shrub native to tropical and subtropical regions around the world, including the Americas, Africa, Egypt and India. The greatest diversity of wild cotton species is found in Mexico, followed by Australia and Africa. Cotton was independently domesticated in the Old and New Worlds. The fiber is most often spun into yarn or thread and used to make a soft, breathable, and durable textile. The use of cotton for fabric is known to date to prehistoric times; fragments of cotton fabric dated to the fifth millennium BC have been found in the Indus Valley civilization, as well as fabric remnants dated back ...

Mercerised Cotton
Mercerisation is a textile finishing treatment for cellulose fabric and yarn, mainly cotton and flax, which improves dye uptake and tear strength, reduces fabric shrinkage, and imparts a silk-like luster. Development The process was devised in 1844 by John Mercer, who treated cotton with solutions of20–30% sodium hydroxide followed by washing. Mercer observed that the treatment shrank the fabric and increased its tensile strength and affinity for dyes. In the original process of Mercer, no tension was applied. The product was termed ''fulled cotton'', a nod to the process of fulling in woven wool fabric. Mercer regarded the increased affinity for dyes as the most important technical aspect. Mercer also experimented with sulfuric acid and zinc chloride solutions and discovered the parchmentising effect of sulfuric acid. The silk-like lustre now commonly associated with mercerising is produced by tension and was discovered by Horace Lowe in 1889. Process Treatment wit ...

Silk Surfacing
Silk surfacing was a surface finishing of cotton to obtain an appearance similar to silk. Process In contrast to other imitative finishes such as mercerizing, In Silk surfacing, real silk was used in this treatment. Cotton was treated with acid and then silk waste (mixed) solution cotton to provide a lustrous appearance. Treatment The steps are as follows: # Soaking of cotton yarns in Tannic acid Tannic acid is a specific form of tannin, a type of polyphenol. Its weak acidity ( pKa around 6) is due to the numerous phenol groups in the structure. The chemical formula for commercial tannic acid is often given as C76H52O46, which corresp ... or other metallic acid. # Soaking in a solution of pure silk (of dissolved Silk waste/remnants in some acid.) # Dry # Passing through rollers. The cotton is encased with silk. Although the finish was less durable, was adapted for selected products only that were less likely to wash. See also * Finishing (textiles) * Plasma ...

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 not done as 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 machi ...

Heatsetting
Heat setting is a term used in the textile industry to describe a thermal process usually taking place in either a steam atmosphere or a dry heat environment. The effect of the process gives fibers, yarns or fabric dimensional stability and, very often, other desirable attributes like higher volume, wrinkle resistance or temperature resistance. Very often, heat setting is also used to improve attributes for subsequent processes. Heat setting can eliminate the tendency of undesirable torquing. At the winding, twisting, weaving, tufting and knitting processes, the increased tendency to torquing can cause difficulties in processing the yarn. When using heat setting for carpet yarns, desirable results include not only the diminishing of torquing but also the stabilization or fixing of the fiber thread. Both twist stabilization and stabilization of frieze effect are results of the heat setting process. Heat setting benefits staple yarns as well as bulked continuous filament (BCF) ya ...
