Welcome to fibre world and its application

Super Shrinkable FibreFabrics composed of yarns having differential shrinkable components High shrinkable fibres are produced copolymerization and mild heat treatment of drawn fibres shrinkable levels of 20-25%. Acrylic fibres having super high shrinkable of 35-40% Manufacture-Cytec, USA Applications-pile fabrics, sweaters, hosiery and blankets

Applications

Body-Responsive Hollow FibreScientifically proven to significantly

increase oxygenated blood flow, which cans increase circulation and build strength.

Responds to available light and the energy produced naturally by the body, converting light and they body’s own energy in to the necessary wavelengths that make this usually unavailable energy accessible to the body-improving the body’s circulation and oxygen levels.

Used by all the sportsmen and diabetes patients as well

Uniqueness and applications of the fibre

Nanofibers

Method of production- electro-spinning

A high voltage is used to create and electrically charged stream of polymer solution or melt.

Nano care

Nano-touch Nano composite

Melamine Fiber-forming substance is a synthetic polymer composed of at least 50% by weight of a cross-linked melamine polymer.

Dielectric properties and cross section shape and distribution make it ideal for high temperature filtration application

PropertiesWhite and dyeable Flame resistance and low thermal conductivity High heat dimensional stability Processable on standard textile equipment

Melamine made products

Presently available Superfibre

ZylonCommercial names- PBO (poly- p –phenylene benz – bis-oxazole) .The fibre is a gold coloured and its appearance is similar to kevelar.Toyobo started its production at its Tsuruga plant in October 1998 with 200 tons/year at the beginning and increased to 360 tons / year by 2002. Average tenacity -45gpd .

ApplicationsBullet proof vest,sail of boat & protext.Pumpkin shaped balloon for atmospheric observation (NASA).

Comparison of various fibres

Applications of zylon fibres

Spectra fiber 1000

Has high- strength, light weight polyethylene fibre

Extended chain polyethylene fiber has one of the highest strength to weight ratios of any manmade fiber

Spectra fiber 1000 has tenacity 15 – 20 percent higher than that of Spectra fiber 900

Spectra fiber is, pound-for-pound, 10 times stronger than steel, more durable than polyester and has a specific strength that is 40 percent greater than aramid fiber.

CharacteristicsLight enough to float (.097 Specific Gravity)Excellent vibration dampingLow coefficient of frictionLow dielectric constant makes it virtually transparent to radar

ApplicationsPolice and military ballistic vests and helmetsComposite armor for vehicles and aircraftMarine lines and commercial fishing nets

Hyaluronan- A New Medical FibreIt’s a linear polysaccharide , with a fibre

structure which consists Of repeating disaccharide units of D-glucuronic and

N acetyl –D-glucosamine residues.It can be produced from- bovine vitreous, umbilical cord and rooster comb Trade name-Healon GV

ApplicationsBreast cancerAs a switch to control cell cancer behaviorAs an anti cancer materialIn corneal wound healingRepair of lung injury

Applications

Aids?Ans:Magic fiber

Magic fiber for AIDS diagnosis and treatment

• Ashai Chemical Industry Co. have developed a porous hollow fiber membrane BEMBERG MICROPOROUS MEMBRANE [BMM] to filter out and isolate AIDS virus [acquired immune deficiency syndrome virus] and hepatitis type B in blood.

• BMM is made from cellulose fiber [BEMBERG] regenerated from cuprammonium solutions of cotton linters.

• Spherical B-type hepatitis virus and AIDS virus have a diameter of 42 nm and 90-100 nm. Thus the membrane needs to have pores of 30-40 nm or 40-75 in diameter, respectively, to isolate these viruses.

• BMM has a multi-layer structure of 100-150 layers • Manufacturing technique - wet spinning

ApplicationsCapable of removing virus from plasma and so suppresses its multiplication Complete isolation of virus during plasma

medicines manufacture, the administrationof fractionated plasma-producing medicines for hemophiliacs, and the prevention of virus infection during ordinal plasma transfusion.

BMM is also useful for the isolation of hepatitis non-A non-B virus and in the study of unknown viruses or other physiologically active substances

Power fibers that store solar energy

Heat regenerating fibers are produced from ceramic composites by applying heat insulation processing technology, which utilizes the far infrared radiation effect of ceramic .Zirconium, magnesium oxide or iron oxide can be blended into synthetic fibers, because these materials radiate Ca.60 mW far infrared of wavelengths 8-14 um at a body temperature of 36 0C. These heat reradiating fibers are used for sports wear, bead-sheets, bed-cover materials, etc. It absorbs visible rays and reflects the light of long wavelength, which makes up 95% of sunlight, and converts it into stored heat energy.

The cloths made of solar-α fibers absorbs solar visible radiation efficiently and converted it into heat in the form of infra-red radiation which released in the clothing

Other specifications A futuristic fiber material solar-α has been developed,

which absorbs and preserves the optical energy of the sun.

Solar-α has been employed for a downhill skiing suit
