Chapter 8: Identification of Vegetable Fibers

Article excerpt

General Discussion

This module is intended as a guide to familiarize the trainee with techniques utilized in the identification of the plant fibers which are commonly used in textile products and cordage (cotton, flax, ramie, jute, hemp, etc.). The scope of this module is not intended to include other botanical identifications. This module should be reviewed/reworked in conjunction with several other chapters of the training program manual in order to fully integrate all topics.

Objectives

Upon satisfactory completion of this training module, the trainee will have developed and demonstrated theoretical knowledge and/or practical skills to:

1. use bright field and polarized light microscopy to identify plant tissue and cellular structural features that allow for the classification of the fiber(s) as vegetable, and as bast (stem) fibers, leaf fibers, or seed (fruit) fibers;

2. determine the plant cell wall spiral thickening's direction of twist and apply this information to a botanical identification;

3. make a botanical identification of the fiber source as specifically as possible using reference sources and comparisons; and

4. have an understanding of the processing, dyeing techniques, and end use products of the various vegetable fibers.
