Textiles are made up from natural or man-made fibres or a combination of both. “Fibres are thin‚ hair-like structures” (Blair‚ n.d: online) that are categorized into two types: long filament fibres and short staple fibres. Natural fibres are usually staple‚ whilst man-made fibres are filament‚ with the exception of silk that comes from a natural source. These raw fibres are spun to produce a long‚ continuous thread referred to as yarn‚ which is then used in a series of methods that include‚ stitching

increasingly common in soccer and American football‚ as well as other sports. There are many benefits to synthetic turf‚ like the fact that turf is consistent‚ even playing surface in rain or shine‚ whereas natural grass would get ripped up when wet. Although artificial turf fields have many benefits‚ there are also some consequences

Overview: Nylon is a thermoplastic silky material‚ first used commercially in a nylon-bristled toothbrush (1938)‚ followed more famously by women’s stockings ("nylons"; 1940). It is made of repeating units linked by amide bonds and is frequently referred to as polyamide (PA). Nylon was the first commercially successful synthetic polymer. There are two common methods of making nylon for fiber applications. In one approach‚ molecules with an acid (COOH) group on each end are reacted with molecules

Marine organisms contribute significantly to the oxygen cycle‚ and are involved in the regulation of the Earth’s climate. Shorelines are in part shaped and protected by marine life‚ and some marine organisms even help create new land. Many species are economically important to humans‚ including Nylon Shells (Phapia

fields are now cheaper‚ safer and easier to maintain. Synthetic turf has quickly become the standard field for organizations that are planning on installing a new field. Synthetic turf has two main components that allow for it to be as realistic as possible: synthetic turf blades and infill materials. Rubber has always been the infill material of choice for the past decades‚ but new research proves that it may not actually be the best infill material available. High levels of harmful pollutants and

Synthetic fibers are made from synthesized polymers or small molecules. The compounds that are used to make these fibers come from raw materials such as petroleum based chemicals or petrochemicals. These materials are polymerized into a long‚ linear chemical that bond two adjacent carbon atoms. Differing chemical compounds will be used to produce different types of fibers. Although there are several different synthetic fibers‚ they generally have the same common properties. Generally‚ they are known

Today they’re many thousand different materials. Most of them are different types of clothing‚ or cloth. Good portions of these are combinations of synthetic fibers woven or threaded together to make a final product. These synthetic fibers are a large group of polymers. Synthetic polymers offer more possibilities‚ since they can be designed with molecular structures that impart properties for desired end uses. All fibers are ploy-something or polymers. That means they are long strings of repeating

Synthetic fibers and synthetic fabrics consist of bulk fibers‚ yarns‚ woven cloth or other textile products manufactured from polymer-based materials such as polyamide (nylon)‚ polyester‚ aramid‚ or other spun thermoplastics. Basic product types include: fibers and monofilaments‚ roving and yarn‚ carded and needlepunched non-wovens‚ braided products‚ rope and cordage‚ webbing‚ blankets or batts‚ sleeves or wraps‚ and thread. Bulk chopped fibers or thin‚ continuous fiber filaments are used typically
