which are capable of being shaped, extruded, cast through applying heat (3). Polymers on the other hand are the larger molecules which are made of chains or rings which linked with many monomer units with high melting and boiling point (4). Thermoplastics are the materials that can be re-melted and reused, by applying high temperature and low temperature it can be softened and hardened respectively with no cross link (5). Thermo set are the materials, which can form permanent three dimensional

structure, less pilling and decreased contamination through removal of fluff and lint. The process is usually to pass one or both sides of a fabric over a gas flame to burn off the protruding fibres. Other methods include infra-red or heat for thermoplastic fibers. Singeing of yarns is called "gassing". It is usually the first step after weaving or knitting, though the fabric may be brushed first to raise the surface fibres. Cellulose fibres such as cotton are easily singed because the protruding

It was found that the injection moulding temp. used for specimen preparation had a marked

of polar functional groups at the surface [29–34] or by blending in ethylene–propylene rubber (EPR) which in turn forms a thermoplastic polyolefin (TPO) [35–38]. Other industries such as the building, engineering and biomedical industries have also actively investigated polymer adhesion. The building industry is one of the biggest users of polymers (for example, thermoplastic roofing membranes and other polymer-based structures) and polymer-based sealants. The major application of sealants is in circumstances

pressure. A better alternative is thermoplastic, which can be repeatedly softened and remolded by heat and pressure. However, when heat and pressure are applied to thermoplastic, it can still result in hazardous fires that emit toxins into the air, can clog the incinerator’s grate, and/or can emit very harmful fumes and as well as enable chemical exposure from the resin use of plastic production. At the very least, Sony should begin using the recyclable thermoplastic alternative. Even better would
