Fibers Flashcards
A fiber is defined as:
An elongate structure whose length exceed its breadth.
Fibers are grouped as:
Natural or Artificial.
Natural fibers are subdivided into:
Animal, Mineral or Vegetable.
Textile fibers fall within the range of:
10-50 um in diameter
Individual fibers can vary in length from:
Less than 1cm to thousand of meters
Textile fibers are manufactured from:
A yarn
A yarn is defined as:
A strand of textile fiber in a form suitable for wearing, knitting, braiding, felting, webbing or fabricating into a fabric (US Federal Trade Commission)
Fabrics are defined by method of assembly:
Woven, knitted and non-woven (three major types)
Recognition phase of evidence is:
The subsequent recording and recovery of items relevant for meaningful examination and interpretation.
Fiber transfers maybe:
Primary or Secondary
Secondary fibers are transferred from:
An item
Common method for recovery of fibers:
Tape lifting
The aim of laboratory examination and analysis of fibers is:
To characterize fibers using the most discriminating techniques available
Typical features assessed on fibers:
Diameter, variation along fiber length, fiber shape, surface features, internal details, color and florescence
Fiber type is important to donor and recipient. The potential for a fabric to transfer fibers is called:
Shed-ability
