Edit
The fiber Spandex, too known equally Lycra as well as Elastane is a human made fiber carries the belongings of extended elasticity. It was commencement invented inward 1958 at Dupont chemic companionship which is a polyether as well as polyeurea copolymer. To larn far 85% polyurethane as well as 15% natural latex are used. The generic lift of this fiber is mainly spandex where dissimilar place prefers to purpose dissimilar merchandise lift such equally Elastane inward Europe as well as Lycra is inward UK as well as Latin America. Lycra is the merchandise lift of Dupont which is beingness used generally with all the names. This fiber has increased the diverseness of cloth making with nifty comfort for men, women as well as kids product. Blend with multiple fiber is straight off pop where spandex are generally used for elasticity. Dimensional stability depends on the percent of this fiber is used inward making of fabric.
Physical Properties of Spandex Fiber:
Cross sectional area: Though this fiber is produced as well as extruded through round down orifices it may look equally non round down cross sectional shapes with broad make of forms.. To brand multi-filament yarns private filaments are ordinarily fused together where 12 to fifty filaments tin laissez passer notice purpose to brand a yarn. The linear density of filaments ranges from 0.1 to iii tex (g/km).
Density: It depends on the requirement as well as orifices but it ranges from 1.15 to 1.32 g/cc.
Moisture regain: This is ranges from 0.8 to 1.2%.
Length: Since it is filament fiber as well as then it tin laissez passer notice live of whatever size equally required.
Colour: Closely white or transparent.
Luster : Looks a flake wearisome as well as less bright.
Strength: It is weaker than whatever other filament fiber.
Elasticity: It carries splendid elasticity.
Heat: The rut resistance varies considerably with the dissimilar degrades over 300 flat F.
Flammability: It burns slowly.
Electrical conductivity: It has Low electrical conductivity.
Breaking tenacity: 0.6 to 0.9grams/denier.
Chemical Properties of Spandex Fiber:
Acid: It shows quite practiced resistance mightiness to well-nigh of acids unless long exposure inward atmosphere.
Alkalies: Resistance mightiness against alkali is too good.
Organic solvents: It has resistance to dry out cleaning solvent.
Bleaches: It is affected past times bleaching agent as well as lost the elastic recovery.
Dyeing: Affinity to dyestuffs is good.
