Corn is used; not just foreating but the fibres acquired from it is also used to manufacture prettygarments. This is a natural renewable fibre and does not come from petrochemicals. Dextrose, a material extracted from corn amylum is fermented to makelactic acid. Water from this substance is then removed and is converted into afibre form. A recent innovation in the process of fermenting glucose which isobtained from corn has reduced the manufacturing costs for making lactic acidsconsiderably. Poly Lactic Acid (PLA) is derived from dextrose and the finalproduct made from this is called natural plastic. Corn fibres are initiallyknit into tubes. Then they are flattened and made into a slightly stretchyribbon. The process of extracting corn fibres from polymers is called meltspinning. PLA has a wide range of applications like manufacturing clothing,diapers, interior exterior furnishings, weaving carpets and mattresses,upholstery, and geotextile applications. PLA uses approximately 30 percent lessfossil fuel required to manufacture conventional fibres. Thus it proves to beeco friendly as well.
Corn fibre has similarcharacteristics of Polyester Staple Fibre endowed with the luster of silk. Cornfibre fabrics offer the comfort of cotton, silk etc. These fibres are easilydyeable and can be dyed with dispersion dyes under normal pressure. Afterdyeing, many small holes can be found on the side surface. This enables thefabric to absorb moisture, quick dry, and to breathe freely. They also have theeasy to care quality of synthetics. They are unaffected by UV light. Corn fibrefabrics posses excellent resiliency, crease retention and wicking as comparedwith other natural fibres. These fabrics are being adored for their drape,silky feel, long-lasting and moisture properties. They are decomposable and canbe recycled into fertilizers easily. Its CO2 and CO emission while burning isvery low. It has a high melting point, and high crystallization degree. It is akind of yogurt polymer. Corn knitted fabrics will not stimulate the skin, andhence is non-allergic in nature. It offers good heat resistance and elasticity.
Corn fibres can be spun into pureyarn and also with an effective blend of cotton, wool, viscose and otherchemical fibres. The fibres can be processed into staple fibre, multifilamentand monofilament. It provides low index of refraction, which provides excellentcolor characteristics to the fabric. It is antimicrobial and biodegradable aswell.
Clothing with high tech naturewhich is environmentally friendly is the focus of the textile industriescurrently. Despite of the fact that corn fibres are rigid and frail in nature,these fabrics offer a unique combination of options to consumers and haveattracted much attention. They give the comfort of natural fabrics such ascotton, silk and wool, and also prove to be a performance wear. This will serveas an environmentally friendly alternative to cotton. At present, it is famousin Europe and US and is expected to be a globally demanded textile product inthe years to come.
