ALLOCATE THE FABRIC ACCORDING TO THE TYPE OF FIBRE THEY HAVE
Plant fibres: Animal fibres: Synthetic fibres:
COTTON WOOL SILK RAYON NYLON LINEN ACRYLIC
WHICH TYPES OF FABRICS IS LIKELY TO PILL MORE THAN OTHERS?
COTTON: is a single elongated cell. Looks flat, spirally twisted ribbon-like tube under the micrscope.
WOOL: irregular, roughly cylindrical, multicellular structure with tapered ends. three basic layers are shown under the microscope (epidermis, cortex, medulla)
SILK: straight and smooth. Raw fibre, composed of two filaments, has elliptical shape under the microscope.
POLYESTER: generally smooth and straight and the cross-section is round
NYLON: generally fine, round, smooth and translucent. Sometimes it has a shiny appearance, if it looks dull, it will also be dotted under the microscope.
Mace Snag Testing
The test consists of a tubular specimen that is placed on a rotating cylindrical drum. Then a mace (Spiked ball) bounces randomly against the rotating specimen for 600 rotations. Snags are produced to a degree affected by a variety of factors. The degree of fabric snagging is then evaluated by comparison of the tested specimens with visual standards. The observed resistance to snagging is reported on a scale ranging from 5 (no or insignificant snagging) to 1 (very severe snagging)
