3D Textiles
3D textiles are three-dimensional structures made with different manufacturing methods such as weaving, knitting, braiding, or nonwoven, or made with alternative technologies. 3D textiles are produced with three planar geometry, opposed to 2D textiles that are made on two planes.The weave in 2D textiles is perpendicular. The yarn is fed along two axis: length (x-axis) and width (y-axis), while 3D textiles also have a perpendicular weave, but they have an extra yarn with an angular feeding (z-axis) which creates thickness. 3D weaves are orthogonal weave structures, multilayer structures, and angle interlocks. 3D textiles have more manufacturing opportunities, various properties, and a broader scope of applications. These textiles have a wide range of applications, but they are most commonly used where performance is the primary criterion, such as technical textiles. Composite materials, manufacturing is one of the significant areas of using 3D textiles. 3D structures have two kinds ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Socks
A sock is a piece of clothing worn on the feet and often covering the ankle or some part of the calf. Some types of shoes or boots are typically worn over socks. In ancient times, socks were made from leather or matted animal hair. In the late 16th century, machine-knit socks were first produced. Until the 1800s, both man-made and machine-knit socks were manufactured, but the latter technique become more common in the 19th century. One of the roles of socks is absorbing perspiration. As the foot is among the heaviest producers of sweat in the body, it can produce over of perspiration per day; socks help to absorb this sweat and draw it to areas where air can evaporate the perspiration. In cold environments, socks made from cotton or wool help warm up cold feet which in turn, helps decrease the risk of getting frostbite. Thin socks are most commonly worn in the summer months to keep feet cool. Light colored socks are typically worn with sports shoes and dark colored socks with ...

Bulletproof Vest
A bulletproof vest, also known as a ballistic vest or a bullet-resistant vest, is an item of body armor that helps absorb the impact and reduce or stop penetration to the torso from firearm-fired projectiles and fragmentation from explosions. The vest may come in a soft form, as worn by many police officers, prison guards, security guards, and some private citizens, used to protect against stabbing attacks or light projectiles, using metallic or para-aramid components. Soldiers, police tactical units, marines, and special operations forces wear hard armors, either in conjunction with soft armor or alone, to protect against rifle ammunition or fragmentation. History Early modern era In 1538, Francesco Maria della Rovere commissioned Filippo Negroli to create a bulletproof vest. In 1561, Maximilian II, Holy Roman Emperor is recorded as testing his armor against gun-fire. Similarly, in 1590 Sir Henry Lee expected his Greenwich armor to be "pistol proof". Its actual effectiveness ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Textile
Textile is an umbrella term that includes various fiber-based materials, including fibers, yarns, filaments, threads, different 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 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 jackets, spacesuits, and doctor's gowns. Textiles are divided into two groups: Domestic purposes onsumer textilesand technical textiles. In consumer textiles, aesthetics and comfort are the most important factors, but in technical textiles, functional properties are the priority. Geotextiles, industrial textiles, medical textiles, and many other areas are examples of technical textiles, whereas clothing and ...

Auxetics
Auxetics are structures or materials that have a negative Poisson's ratio. When stretched, they become thicker perpendicular to the applied force. This occurs due to their particular internal structure and the way this deforms when the sample is uniaxially loaded. Auxetics can be single molecules, crystals, or a particular structure of macroscopic matter. Such materials and structures are expected to have mechanical properties such as high energy absorption and fracture resistance. Auxetics may be useful in applications such as body armor, packing material, knee and elbow pads, robust shock absorbing material, and sponge mops. History The term ''auxetic'' derives from the Greek word () which means 'that which tends to increase' and has its root in the word (), meaning 'increase' (noun). This terminology was coined by Professor Ken Evans of the University of Exeter.. One of the first artificially produced auxetic materials, the RFS structure (diamond-fold structure), was inve ...

3D Printing
3D printing or additive manufacturing is the Manufacturing, construction of a three-dimensional object from a computer-aided design, CAD model or a digital 3D modeling, 3D model. It can be done in a variety of processes in which material is deposited, joined or solidified under Computer Numerical Control, computer control, with material being added together (such as plastics, liquids or powder grains being fused), typically layer by layer. In the 1980s, 3D printing techniques were considered suitable only for the production of functional or aesthetic prototypes, and a more appropriate term for it at the time was rapid prototyping. , the precision, repeatability, and material range of 3D printing have increased to the point that some 3D printing processes are considered viable as an industrial-production technology, whereby the term ''additive manufacturing'' can be used synonymously with ''3D printing''. One of the key advantages of 3D printing is the ability to produce very ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bikini Variants
The bikini has spawned many stylistic variations. A regular bikini is a two-piece swimsuit that together covers the wearer's crotch, buttocks, and breasts. Some bikini designs cover larger portions of the wearer's body while other designs provide minimal coverage. Topless variants are still sometimes considered bikinis, although they are technically not a two-piece swimsuit.Bikini , Swimsuit Styles Terminology While the name bikini was applied to the skimpy fashion that first revealed the wearer's navel, the fashion industry considers any two-piece swimsuit a bikini. Modern bikini fashions today are characterized by a simple, brief design: two triangles of fabric that form a bra and cover the woman's |
Tights
Tights are a kind of cloth garment, most often sheathing the body from the waist to the toe tips with a tight fit, hence the name. They come in absolute opaque, opaque, sheer and fishnet styles — or a combination, such as the original concept of the American term pantyhose with sheer legs and opaque panty. Terminology and related clothing When made of fine silk, this hosiery was considered to be a stocking. When nylon fibers were developed and introduced in the 1940s, these stockings were referred to as nylons. When the separate legs were woven together with a panty that covered the lower torso up to the waist in a single, integrated format, the term pantyhose was coined, since it was a one piece construction of a panty with a pair of separate hose, one for each leg. This joining together eliminated any need for garters for holding up each separate leg covering. In American English, the difference between pantyhose and tights is determined in the weight of the yarn used and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
I-beam
An I-beam, also known as H-beam (for universal column, UC), w-beam (for "wide flange"), universal beam (UB), rolled steel joist (RSJ), or double-T (especially in Polish language, Polish, Bulgarian language, Bulgarian, Spanish language, Spanish, Italian language, Italian and German language, German), is a beam (structure), beam with an or -shaped cross section (geometry), cross-section. The horizontal elements of the are flanges, and the vertical element is the "web". I-beams are usually made of structural steel and are used in construction and civil engineering. The web resists shear forces, while the flanges resist most of the bending moment experienced by the beam. The Euler–Bernoulli beam equation shows that the I-shaped section is a very efficient form for carrying both bending and shearing (physics), shear loads in the plane of the web. On the other hand, the cross-section has a reduced capacity in the transverse direction, and is also inefficient in carrying torsion ( ...
