Shrinkage (fabric)
Dimensional stability (in fabric) 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 shrinkages is the release of stresses and strains introduced in manufacturing processes. 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 dimensional stability of textile materials is an important quality parameter. Failing and unstable materials can cause deforming of the garments or products. Shrinkage is tested at various sta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, different #Fabric, fabric types, etc. 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: Domestic purposes [consumer textiles] and technical textiles. In consumer textiles, Aesthetics (textile), aesthetics and Textile performance#Comfort, comfort are the most important factors, but in technical tex ...

List Of Laundry Topics
This is a list of laundry topics. Laundry is the washing of clothing and linens (e.g. sheets and towels). Laundry processes are often done in a business, room or area in a home or apartment building, reserved for that purpose; this is referred to as a laundry room. The material that is being washed, or has been laundered, is also generally referred to as ''laundry''.

Dry Clean
Dry cleaning is any cleaning process for clothing and textiles using a solvent other than water. Dry cleaning still involves liquid, but clothes are instead soaked in a water-free liquid solvent. Tetrachloroethylene (perchloroethylene), known in the industry as "perc", is the most widely used solvent. Alternative solvents are 1-bromopropane and petroleum spirits. Most natural fibers can be washed in water but some synthetics (e.g., viscose, lyocell, modal, and cupro) react poorly with water and must be dry-cleaned. History Dry cleaning originated with American entrepreneur Thomas L. Jennings. Jennings referred to his method as “dry scouring”. French dye-works operator Jean Baptiste Jolly developed his own method using kerosene and gasoline to clean fabrics. He opened the first dry-cleaners in Paris in 1845. Flammability concerns led William Joseph Stoddard, a dry cleaner from Atlanta, to develop Stoddard solvent (white spirit) as a slightly less flammable alternative ...

Wet Cleaning
Wet cleaning refers to methods of professional cleaning that, in contrast to traditional dry cleaning, avoids the use of chemical solvents, the most common of which is tetrachloroethylene (commonly called perchloroethylene or "perc"). Environmental groups and the United States Environmental Protection Agency have indicated that such alternative "wet cleaning" methods are better for the environment than perc, and proponents of wet cleaning state that these methods can be used without shrinking or otherwise damaging garments that typically require dry cleaning. Computer-controlled wet cleaning machines, special dryers, safe detergents and non-toxic spot removers make wet cleaning an environmentally sound method. Wet cleaning machines have controls that allow them to safely and efficiently clean a wide variety of garments in water. Detergents and spot removers are made of ingredients that are safer for workers and the environment, yet are as safe and effective at removing soils, st ...

Laundry Symbol
A laundry symbol, also called a care symbol, is a pictogram indicating the manufacturer's suggestions as to methods of washing, drying, dry-cleaning and ironing clothing. Such symbols are written on labels, known as care labels or care tags, attached to clothing to indicate how a particular item should best be cleaned. While there are internationally recognized standards for the care labels and pictograms, their exact use and form differ by region. In some standards, pictograms coexist with or are complemented by written instructions. Standards GINETEX, the France-based European association for textile care labelling, was formed in 1963 in part to define international standards for the care and labelling of textiles. By the early 1970s, GINETEX was working with ISO to develop international standards for textile labelling, eventually leading to the ISO 3758 standard, ''Textiles – Care labelling code using symbols''. ISO 3758 was supplemented in 1993, revised in 2005 and a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wool
Wool is the textile fibre 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 properties similar to animal wool. As an animal fibre, wool consists of protein together with a small percentage of lipids. This makes it chemically quite distinct from cotton and other plant fibres, 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 lac ...

Calendering
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 mach ...

Sanforization
Sanforization is a treatment for fabrics to reduce shrinkage from washing. The process was patented by Sanford Lockwood Cluett (1874–1968) in 1930. It works by stretching, shrinking and fixing the woven cloth in both length and width before cutting and producing, to reduce the shrinkage which would otherwise occur after washing. The original patent mentioned "goods of cotton, linen, woolen, silk, rayon, and combinations thereof". Process The cloth is continually fed into the sanforizing machine and therein moistened with either water or steam. A rotating cylinder presses a rubber sleeve against another, heated, rotating cylinder. Thereby the sleeve briefly gets compressed and laterally expanded, afterwards relaxing to its normal thickness. The cloth to be treated is transported between rubber sleeve and heated cylinder and is forced to follow this brief compression and lateral expansion, and relaxation. It is thus shrunk. The greater the pressure applied to the rubber sleeve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heat Setting
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 ...

Mercerizing
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 w ...

Weaving
Weaving is a method of textile production in which two distinct sets of yarns or threads are interlaced at right angles to form a fabric or cloth. Other methods are knitting, crocheting, felting, and braiding or plaiting. The longitudinal threads are called the warp and the lateral threads are the weft, woof, or filling. (''Weft'' is an Old English word meaning "that which is woven"; compare ''leave'' and ''left''.) The method in which these threads are interwoven affects the characteristics of the cloth. Cloth is usually woven on a loom, a device that holds the warp threads in place while filling threads are woven through them. A fabric band that meets this definition of cloth (warp threads with a weft thread winding between) can also be made using other methods, including tablet weaving, back strap loom, or other techniques that can be done without looms. The way the warp and filling threads interlace with each other is called the weave. The majority of woven produc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
