AcrylicAcrylic fibers (polyacrylonitrile) are
copolymers of vinyl acetate and methyl acrylate. The acrylonitrile (-CH2-CH[CN]-)x is usually combined with
small amounts of other chemicals to improve the ability of the resulting fiber to absorb dyes.
Minimum of 85% acrylonitrile in their chemical structure .
Special Properties of Acrylic
Color to Kayastain(Q): RedBurning Properties:
Burns & melts, black smoke. Smell like meat. Hard and brittle black ash.
Moisture Regain: 2%Solubility: 65%KSCN, DMF.Microscopic View:
Glass rod like structure. Slight irregular striations along its length. Variation in diameter.
General Properties of Acrylic
Outstanding wickability & quick drying to move moisture from body surface.
Flexible aesthetics for wool-like, cotton-like, or blended appearance.
Resistant to moths, oil, and chemicals.Dyeable to bright shades with excellent fastness.Superior resistance to sunlight degradation.Easily washed, retains shape.
ACRYLICAdvantages Disadvantages
