SILK

MICROSCOPIC VIEWCROSS SECTIONAL STRUCTURE AND LONGITUDENAL STRUCTURE

BY BURN TEST

Burns slowlyIt shrinks from the flame.It is self-extinguishing i.e. it burns itself out.Its smells like burn hairIts gives out a little or no smoke.It residue the irregular soft bead.After burns it convert black ashes.

BY SOLUBILITY TEST

IN-SOLUBLEMeta cresolAcetone 100%Xylene boiling

COTTON FIBER

MICROSCOPIC STRUCTURELongitudenal Structure And Cross-sectional structure:

BY BURN TEST

Burns quickly and leaves a yellow flame.Its smells like burning paper.The ash is fine and soft.The ash lefties easily crumbled.

MICROSCOPIC STRUCTURE:LONGITUDENAL AND CROSS SECTIONAL STRUCTURE

BY BURNING TEST

Burns with an orange sputter color.It does not melt.It has a strong odor of burning hair.After burning it convert into black ashes.

MICROSCOPIC VIEWLongitudinal And Cross-sectional Structure:

BY BURNING TEST

Slow to ignite.Smells like burning paper.The ashes very brittle.

POLYSTERMICROSCOPIC STRUCTURE

LONGITUDENAL AND CROSS-SECTIONAL STRUCTURE

BY BURNING TESTIt will shrink from the flame.The melting, burning ash can bond quickly to any surface it drips on including skin. The smoke from polyester is black with a sweet smell. The extinguished ash is hard.

ACRYLICMICRO-SCOPIC STRUCTURE

LONGITUDENAL AND CROSS SECTIONAL STRUCTURE

BY BURN TESTAcrylics burn readily due to the fiber content and the lofty.A match dropped on an acrylic blanket can ignite the fabric which will burn rapidly unless extinguished. The ash is hard.The smell is acrid.

NYLONMICRO-SCOPIC STRUCTURE

LONGITUDENAL AND CROSS-SECTIONAL STRUCTURE

BY BURNING TESTIts melts and then burns rapidly if the flame remains on the melted fiber.Plastic burning like odor.After burning it convert round,black bead ashes.

RAYONMICROSCOPIC STRUCTURE

LONGITUDENAL AND CROSS SECTIONAL STRUCTURE

BY BURN TESTIt is a regenerated cellulose fiber which is almost pure cellulose.Rayon burns rapidly and leave only a slight ash.The burning smell is close to burning leaves.
