According to some reports, it uses less water and uses less energy than the production of cotton. The project called CARBIO, is developing hybrid composite materials to produce lighter, cheaper, and environmentally sound parts. A continuous fibre such as natural silk or synthetic is known as filament rather than staple fibre. Papermaking - Papermaking - Natural fibres other than wood: Since cellulose fibre is a major constituent of the stems of plants, a vast number of plants represent potential sources of paper; many of these have been pulped experimentally. It has a natural sheen and is long and strong. It has been specially developed for our customers who need a cleaner product as “E0” (less Shives). Compared to synthetic glass fibre reinforced composites, natural flax fibre reinforced composites suffer from relatively poor moisture resistance because of the presence of hydroxyl and other polar groups in various constituents of the fibres. There are two types of synthetic fibres — artificial fibres and true synthetics. Synthetic fibre is initially produced as single filaments, made when liquid polymer is forced through fine holes in a device called a spinneret. A UK funded project is aiming to develop automotive structures using flax fibres and a bio-epoxy resin intermingled with carbon fibres. DI 15 has been developed for the non-woven industry to produce webs and for composite (alone or mixed with other natural or synthetic fibers). (d) The common name of coconut fibre is coir. NATURAL FIBRE Any hair like raw material directly obtainable from an animal, vegetable or mineral source that can be convertible after spinning into yarns and then into fabric. Cotton is very breathable which it comfortable to wear especially in hot weather so that moisture can escape. (e) Fabrics are made first by spinning the fibre to make yarn and then weaving or knitting the yarn. Di Bella et al. Other natural fibres Synthetic fibres are man-made fibres developed in laboratories. limited by natural fibres such as flax, cotton, silk, wool and plant fibres for different applications. 38 views. Each boll contains up to 20,000 staple fibres. This necessitates study of the flax fiber strength distribution and Our organic linen collection is a good example of 100% biodegradable products. Some natural fibers are less eco-friendly than others because some plants require more water. In ancient Egypt, cotton as well as flax were cultivated near the river Nile and were used for making fabrics. This is a natural plant that generally has a more eco friendly growing and harvesting stage than say for example cotton, or compared to the making a synthetic fibre like polyester.
