High performance, fibers, organic, inorganic, future directions, such as mechanical, dimensional stability, and the properties of polymers and non-dimensional fibers such as heat resistance. Growth leads to fiber products with abnormal properties. Likewise, high efficiency fibers are important engineering products and are widely used due to excellent mechanical properties with size stability. They have found wide use with fiber optic reinforcement and can be used in many applications such as code, rope, productivity fabric, electronic packaging, sports equipment and fiber optic. The highest intensity and elastic modules reported about these fibers are still well known that they are still much lower than theoretical values. The large open gap between theoretical values and actual results encourages scientists to work and improve mechanical properties.
Fabric filtration is a widely used method to control particulate emissions. In fabric filtration, particulate-laden gases pass through a series of parallel filter bags, leaving the fabric dusty. To use the cloth filter or bag filter for a long time, you should periodically clean the dust on the cloth surface and remove it from the bag filter. A new cloth leaves behind a residual mass of dust that becomes the filter material after several uses and cleaning cycles. This phenomenon is responsible for the high-efficiency fine particle filtration properties of bag filters. The automotive industry is primarily concerned with the design, manufacture and sale of automobiles and relies on ancillary sectors such as suppliers of rubber, glass, steel, plastics, aluminum, textiles and other accessories. It is estimated that over 75 million vehicles were produced worldwide during 2011, of which approximately 60 million were passenger cars. India is the 6th largest automobile producer in the world, producing approximately 3.9 million units per year, and is expected to continue growing at 16-18% per year. According to the Society of India Automobile Manufacturers, annual car sales will increase to 5 million units by 2015 and more than 9 million units by 2020.
CHEMICAL STRUCTURE OF HIGH PERFORMANCE FIBERS
- Aromatic Polyamides
Aromatic polyamides or aramid polymers include both maramide and paramid polymers. Maramide means that the meta-aramid is linked to the Meta position of the phenylene ring, and paramid means that the para-aramid is linked to the para position of the phenylene ring.
One of the best-known fibers in the aramid family, Kevlar is based on the polymer poly (phenyleneterephthalamide) (PPTT). The chemical structure of Kevlar fibers is shown figs. 6 shows the monomers and polymerization process used to make PPTA or Kevlar.
Chemical Structure of Kevlar® polymer
NOMEX Aramid is based on Phenillidiofhatamide, which commercialized DuPont in 1967 in 1967 as Aramid fiber. Kevlar between Kevlar between Kevlar and Nomex is that Kevlar is para aramid, if Kevlar is Para aramid ID, is Meta amide. A small difference in structure leads to a significant difference between physical and mechanical properties. For example, in a Kevlar, a PPPenyleneththtamide, the polymer chain is difficult and difficult to have a polymer chain due to phenylene ring and amide groups. Related to the provision points. However, in NOMEX fibers, phenylene ring and amide groups are randomly linked to induce the lower stretching module, as an irregular structure chain and as irregular structural chains.

TYPES OF HIGH PERFORMANCE FABRIC
- Polyolefin fibers
In recent years, there are important demand for various applications in various applications in various applications such as daily life and electric materials, medical, transportation, geotech style, and sports. Results, excellent inner chemical resistance, reasonable thermal stability capable of producing low cost. The polyolefin fibers may be formed as a polymer formed by a latch that is formed by a polymerization of polymerization composed of an olefin (alkenes) such as ethylene, propylene or other olefin block. Indeed, dominant products for polyolefin fibers are polyethylene with high-rise (HDPE) and polypropylene, which are very diverse plastics, which are very versatile and various materials, 70 and 14.5 billion dollars. In 2019, the World Market Super Polymer Polyethylene (UHMPE) or polyethylene fiber (HPPE) is a high strength, which is a high module based on a simple and high-cost polyethylene molecule. These fibers are chemically the same as normal PE. For example, as constructing a very long chain, such as constituting a very long chain, the orientation of high-level and high crystallization is the orientation of high-level crystallization, and the current high efficiency polyethylene fiber (HHPE) is Dyneema HIGH PERFORMANCE DYNEEMA and Japanese joints in the Netherlands Venture to be commercially available from venture toys / DSM. Another brand is – Spectra®, which produced US Honeywell (formerly agonist signals or federated fibers).
- Inorganic Fiber
Inorganic fibers can be described as fibers composed of more than 99% inorganic and organ metallic compounds. It’s basically made of ceramic or metal, not a polymer precursor. For this reason, conventional textile fiber production systems are generally not suitable for inorganic fiber production. Relatively complex processes such as chemical vapor deposition, modified radiation techniques and high-temperature processing are used. Inorganic fibers are commonly used as a staple or continuous form reinforcing element in composite materials due to their brittle nature. Glass and carbon fibers are the most commonly used inorganic fibers in composite materials. High thermal stability (above 1000°C for C fibers) and corrosion resistance are among other properties superior to organic materials. Four commercially available inorganic fibers: carbon (CF), glass, and boron, their production methods and properties are discussed.
- Carbon Fiber
Essentially organic, but CF is classified as weapons due to pure SP2-Squabble carbonated chemicals. The theoretical strength of one graphite decision is calculated at 150 GPa. However, , however, a practical solution has not yet reached this value, but Hexcel announced the strength of stretching 8 GPA in the fan precursor recently. I have been reported that inevitable defects on other scales of have been registered.
HIGH PERFORMANCE FIBERS FOR TEXTILES
As the basic building blocks of all textiles, fibers and their properties are critical to the performance of the final textile product. When you think of a fabric as a three-dimensional structure, you can think of the filament as a one-dimensional unit. With a large number of fibers, there are many fiber options to create fabrics in warp, weft and thickness directions. How good can the properties of textile products be? This largely depends on the fiber selection and the fiber assembly technique. In a floor-scale structured yarn, there is still freedom of choice, and know what kind of fiber is used. Donation, material scientists and engineers for this core role were carefully cooperated to enrich the fiber pool. In particular, for recent decades, textile databases constantly meet the needs of edema from new industries and support the rapid way of modern consumers. Due to the operation of manipulating the chemicals of the substance inside the fiber, the fibers are no longer a key scale size. Even solar cells with different types of materials and hierarchies have been developed as one fiber. This chapter looks at the development of textiles in several classic functional categories to make choices easier and smarter when designing and producing high-quality textiles. We will consider high-strength, temperature-controlled, moisture-proof, elastic, radiation-protected and fire-resistant fibers.
DEVELOPMENT OF FILTER CLOTH
The design of the filtering medium depends on heat and chemical conditions, filtering requirements, equipment consideration and cost. The type of polymer to be selected for filtering depends on the heat and chemical state of the material to be filtered. Natural fibers, such as those that can produce high efficiency media for filtering, but can produce very efficient media in durability, are limited to use compared to synthetic fibers. Polyamides, polyesters and polypropylene can be used as fabrics for filtering, but PTFE (Fluor ethylene Polytetra) for manufacturing bags for manufacturing bags is in vivo, because it is resistance to all chemicals, and biocompatibility and hydrophobicity in nature. Low melting points, low thermal conductivity, and low load capacity are used only for optical low speed applications. The filter fabric is used to maximize particles from liquids and is not always necessary for absolute sharpness. In some gravarials, the vacuum screening operation of the filter fabric is for capturing particles that simply exceeds a specific size, and in other filtering systems, the filtering system can be allowed to measure the solids of the filter, and the necessary sharpness may be achieved. Various fiber structures such as mono and total volume, multilayer (porous or fiber diameter) are different from the diameter of porous or fibers, and composed of layered layers) are used for manufacturing and specific purposes. Bio Folding remains a problem that is still not resolved. The bacteriostatic effect reduces the effect of bromide on the outer surface of the filter. Nano Complex Membrane showed promising antimicrobial activity for mane gal bacteria. By the method, the silver nanoparticles presented by silver nanoparticles presented by silver nanoparticles represented by silver nanoparticles (silver nanoparticles presented by silver nanoparticles presented and particles are preferably distributed on the upper and lower films). In addition to synthesizing nano particles and further dispersed in the polymer solution, the spherical nano particles are uniformly uniformly uniformly in the inner pores, but also reducing the decrease in 90% E. coli in the cells compared to uniform It was found to be. . The failure of the SITU considers a simple and reproducible methodology for the manufacture of the membrane of the membrane of the polysulfone of the antimicrobial agent containing silver nano particles.
TEXTILES IN AUTOMOTIVE INDUSTRY
Clothing, technical fiber fabrics form a part of the car in a car in a premium segment, especially in a premium segment. Textile is used in an indoor decorative seat, headline, door panel, parcel lathe, carpet floor, hidden / secure, component – airbag material, air / fuel filter, aesthetic term of visible coating from the perspective of air / fuel filters, hose and seat belt. In principle, approximately 1215kg of fiber material is assumed to be included in the tipper machine. The global consumption of the fiber used in the automotive industry is estimated to be more than 0.5 million tons, which is about 2.2% of the total weight of the car. Almost 80% of India’s cars use fabrics and use the rest of the premium segment to use knit fabrics. Therefore, textiles are an essential component of automobiles. Mobile Tech is the term used for technical textiles used in the automotive sector, which includes the use of textiles in all aspects of road, rail and space transportation. A significant technical input is required to meet both aesthetic and durability requirements while taking into account important factors such as end-user comfort and safety. In addition, due to their lighter weight than metal components, the use of fibers can result in significant fuel savings.
Filtration is considered a core stone cleaning of water and wastewater, and is used for a variety of purposes such as deposited dehydration and concentration of any solution. The material can also be removed from a molecular and ion chemical species to a membrane filtering technology extended from large visible particles. The filtering performance depends on the operating conditions such as fluid properties, filtering speed, and filtering media. Among them, the correct choice of filtering media / membrane materials in the filtering process is often the most important considerations to ensure effective separation.
Filter media can be classified as building materials such as wool, underwear, glass fiber, porous carbon, metal and region. Recently, new polymeric materials were used individually and / or mixed in filtration processes for water and wastewater treatment. The purpose of this chapter is to attract reviews of organizational filtering materials in filtration applications in existing filtering, as an advanced membrane process.
