A scrim is a woven material, either finely woven lightweight fabric widely used in theatre, or a heavy, coarse woven material used for reinforcement in both building and canvas making.[ citation needed ]
A scrim or gauze is often a very light textile made from cotton, flax or other materials. It is lightweight and translucent, which means it is often used for making curtains.[ citation needed ] The fabric can also be used for bookbinding and upholstery.[ citation needed ]
Scrims have seen extensive use in theatre.[ citation needed ] There are several types used for special effects. The variety typically used for these purposes is called sharkstooth scrim. However, in theatre, a scrim can refer to any such thin screen and is made of a wide variety of materials. Sharkstooth scrim is woven and earns its name because the weave resembles a set of triangles that resemble a shark's teeth with openings similar in size to a window screen.
The most common use of scrim is the 'reveal effect', in which an actor or scene is made to appear or disappear by using the scrim and appropriate lighting. Other common effects include sharp silhouettes, backlit from behind the scrim, or other shadow effects (shrinking and growing a shadow). [1]
The bobbinet/bobbinette is a type of scrim that has a hexagonal hole shape and comes in a variety of hole sizes. It is used for a number of lighting effects in the film and theatre industries.
Scrim is also used in clothing, usually covering the face or head. This allows the wearer to look out while preventing others from seeing in. This may also be combined with camouflage to completely hide a person, such as a sniper, [2] hunter [3] [ better source needed ], or wildlife photographer. The term "helmet scrim" refers to the practice of adorning a helmet with scrim and/or other fabrics to make its shape less obvious; [4] [5] the practice of adding scrim to a helmet is often done as much for reasons of perceived status as it is for reasons of actually improving camouflage. [6] [7] British and other forces have also made constant use of issued or privately purchased scrim fabric as a sort of improvised scarf that can be quickly converted into a face veil or similar. [8] [9] [10]
A scrim was an integral part of the Beijing Olympic Stadium in Beijing. It was the screen running around the top of the stadium during the opening ceremonies on which all kinds of scenes were projected. Li Ning ran around it just before the cauldron lighting for 2008 Summer Olympics.
A scrim (also called a screen) is used as an acoustically transparent covering for a loudspeaker to protect the diaphragm and dust cap, or as an air filter element to protect the voice coil and other components of the transducer.
A scrim can be used on the back of a perforated (acoustically transparent) movie screen to reduce the amount of light shining through it.
A scrim can be used as a base layer for automotive loop pile and cut pile carpeting.
Scrims both reflect and transmit light. This means that if a light from a front-of-house position is shone at a scrim, then both the scrim and everything behind it will be lit. This can lead to a variety of interesting effects:
In general, anything that is lit will be seen on both sides of a scrim: scrims do not absorb light. Scrim can also be used in theater in combination with a cyclorama or backdrop. The idea is similar to the other uses. When the drop is lit (or images or video are rear-projected onto the back of the drop), the images or colors projected are visible. However, when the drop is not lit, the images or colors will disappear. A scrim can also help dull the image, creating a greater sense of depth.
Another effect is caused by layering two scrims, or even by placing a mirror behind a scrim and lighting it: the familiar moire effect. This can often cause audience disorientation.[ citation needed ]
The technique of using scrim as a reinforcement occurs commonly in the manufacture of glass-fiber or carbon-fiber composites: scrim layers may cover the exterior surface of the carbon-fiber laminate for an improved protective surface. Jute scrim can reinforce plaster in sculpture when casting or working directly in plaster.[ citation needed ]
A similar usage of the term is found in sailcloth manufacture, where scrim is a strong loose weave of fibers laminated into the cloth to provide extra strength and stability to sails.[ citation needed ]
In carpentry, scrim is a very heavy, coarsely-woven fabric (similar to hessian or to coarse canvas) which is stretched over interior boards to provide support for wallpaper and to add extra rigidity. This method of construction, widely used in older houses, is often referred to as "scrim and sarking", the sarking being the board.
Scrim is also an item that utilizes plies of tissue reinforced with a layer of nylon (much like a fishing line or heavy-duty mono-filament) or cotton thread. 2-ply tissue 1-ply scrim[ sentence fragment ] The layer of scrim is not counted in the ply count. 2/1 would be a 2-ply scrim.
Scrim is a glass fiber (previously burlap) open-mesh tape used to cover joints in plasterboard/wall board before plastering. It prevents a crack from appearing in the plaster finish at a later date. The roll of tape may be plain or adhesive-coated to facilitate its installation.
Scrim was handed out during World War II to tape windows, so that they should not cause hazardous shrapnel in case of bomb blasts. [11]
Calico is a heavy plain-woven textile made from unbleached, and often not fully processed, cotton. It may also contain unseparated husk parts. The fabric is far coarser than muslin, but less coarse and thick than canvas or denim. However, it is still very cheap owing to its unfinished and undyed appearance.
Yarn is a long continuous length of interlocked fibres, used in sewing, crocheting, knitting, weaving, embroidery, ropemaking, and the production of textiles. Thread is a type of yarn intended for sewing by hand or machine. Modern manufactured sewing threads may be finished with wax or other lubricants to withstand the stresses involved in sewing. Embroidery threads are yarns specifically designed for needlework. Yarn can be made of a number of natural or synthetic materials, and comes in a variety of colors and thicknesses. Although yarn may be dyed different colours, most yarns are solid coloured with a uniform hue.
Linen is a textile made from the fibers of the flax plant.
A mesh is a barrier made of interlaced strands of metal, fiber or other flexible or ductile materials. A mesh is similar to a web or a net in that it has many interwoven strands.
A scrim is a device used in the film and television industries, as well as by photographers, to modify properties of light. There are variations on types of scrim, depending upon its use, whether with natural light, or with man-made light sources. However, their basic use is the same – to reduce intensity and/or harshness of light.
Crêpe, also spelled crepe or crape, is a silk, wool, or synthetic fiber fabric with a distinctively crisp and crimped appearance. The term "crape" typically refers to a form of the fabric associated specifically with mourning. Crêpe was also historically called "crespe" or "crisp".
Hessian, burlap in North America, or crocus in Jamaica and the wider Caribbean, is a woven fabric made of vegetable fibres, usually the skin of the jute plant or sisal leaves. It is generally used for duties of rough handling, such as making sacks employed to ship farm products and to act as covers for sandbags, and for wrapping tree-root balls. However, this dense woven fabric, historically coarse, more recently is being produced in a refined state, known simply as jute, as an eco-friendly material for bags, rugs, and other products.
Sailcloth is cloth used to make sails. It can be made of a variety of materials, including natural fibers such as flax, hemp, or cotton in various forms of sail canvas, and synthetic fibers such as nylon, polyester, aramids, and carbon fibers in various woven, spun, and molded textiles.
Gauze is a thin, translucent fabric with a loose open weave. In technical terms, "gauze" is a weave structure in which the weft yarns are arranged in pairs and are crossed before and after each warp yarn, keeping the weft firmly in place. This weave structure is used to add stability to the fabric, which is important when using fine yarns loosely spaced. However, this weave structure can be used with any weight of yarn, and can be seen in some rustic textiles made from coarse hand-spun plant fiber yarns. Gauze is widely used for medical dressings.
Organza is a thin, plain weave, sheer fabric traditionally made from silk. Many modern organzas are woven with synthetic filament fibers such as polyester or nylon. Silk organza is woven by a number of mills along the Yangtze River and in the province of Zhejiang in China. A coarser silk organza is woven in the Bangalore area of India. Deluxe silk organzas are woven in France and Italy. Organza is distinguished by its crisp hand, stiffness relative to weight, and slippery surface texture.
Theater drapes and stage curtains are large pieces of cloth that are designed to mask backstage areas of a theater from spectators. They are designed for a variety of specific purposes, moving in different ways and constructed from various fabrics. Many are made from black or other darkly colored, light-absorbing material. Theater drapes represent a portion of any production's soft goods, a category comprising any non-wardrobe, cloth-based element of the stage or scenery. Theater curtains are often pocketed at the bottom to hold weighty chain or to accept pipes to remove their fullness and stretch them tight.
Volumetric lighting, also known as "God rays", is a technique used in 3D computer graphics to add lighting effects to a rendered scene. It allows the viewer to see beams of light shining across the environment. Examples of volumetric lighting are seeing sunbeams shining through a window and seeing sunbeams radiating when the Sun is below the horizon, also known as crepuscular rays. The term seems to have been introduced from cinematography and is now widely applied to 3D modeling and rendering, especially in the development of 3D video games.
The manufacture of textiles is one of the oldest of human technologies. To make textiles, the first requirement is a source of fiber from which a yarn can be made, primarily by spinning. The yarn is processed by knitting or weaving, with color and patterns, which turns it into cloth. The machine used for weaving is the loom. For decoration, the process of coloring yarn or the finished material is dyeing. For more information of the various steps, see textile manufacturing.
Textile fibers, threads, yarns and fabrics are measured in a multiplicity of units.
Antique satin, also called satin-back shantung, is any five- or eight-harness (shaft) satin weave that uses slubbed or unevenly spun yarns in the weft (filling). It is reversible in that one side is satin and the other is shantung. It is used for simulating 17th and 18th century silks, and clothing such as blouses, lingerie and evening wear.
Novelty yarns include a wide variety of yarns made with unusual features, structure or fiber composition such as slubs, inclusions, metallic or synthetic fibers, laddering and varying thickness introduced during production. Some linens, wools to be woven into tweed, and the uneven filaments of some types of silk are allowed to retain their normal irregularities, producing the characteristic uneven surface of the finished fabric. Man-made fibres, which can be modified during production, are especially adaptable for special effects such as crimping and texturizing.
The Kamuflirovannyy Letniy Maskirovochnyy Kombinezon or KLMK is a military uniform with a camouflage pattern developed in 1968 by the Soviet Union to overcome the widespread use of night vision optics and devices by NATO countries. This one-piece camouflage coverall became one of the most widely used in the Soviet Union.
A fabric structure is a structure made of fabric, with or without a structural frame made from the weaving of the fabric itself. The technology provides end users a variety of aesthetic free-form building designs. Custom-made structures are engineered and fabricated to meet worldwide structural, flame retardant, weather-resistant, and natural force requirements. Fabric structures are considered a sub-category of tensile structure.
Three-dimensional composites use fiber preforms constructed from yarns or tows arranged into complex three-dimensional structures. These can be created from a 3D weaving process, a 3D knitting process, a 3D braiding process, or a 3D lay of short fibers. A resin is applied to the 3D preform to create the composite material. Three-dimensional composites are used in highly engineered and highly technical applications in order to achieve complex mechanical properties. Three-dimensional composites are engineered to react to stresses and strains in ways that are not possible with traditional composite materials composed of single direction tows, or 2D woven composites, sandwich composites or stacked laminate materials.
Leno weave is a weave in which two warp yarns are woven around the weft yarns to provide a strong yet sheer fabric. The standard warp yarn is paired with a skeleton or 'doup' yarn; these twisted warp yarns grip tightly to the weft which causes the durability of the fabric. Leno weave produces an open fabric with almost no yarn slippage or misplacement of threads.
