Botanical trash present in cotton before and after saw-type lint cleaning
American Industrial Hygiene Association Journal
|June 1, 1976
Summary
Gin cleaning effectively removed stem trash but was ineffective for leaf-like trash. Trash particle size influenced the content of bract, leaf, and cotton seed fragments in lint.
Area of Science:
- Agricultural Engineering
- Textile Science
- Cotton Processing
Background:
- Cotton lint contains various botanical impurities after ginning.
- Understanding the composition of these impurities is crucial for effective cleaning.
Purpose of the Study:
- To quantify the types and amounts of trash in cotton lint before and after cleaning.
- To assess the effectiveness of saw-type lint cleaning on different trash components.
Main Methods:
- Analysis of lint samples using the Shirley Analyzer.
- Sifting trash particles within a specific size range (595-3360 µm).
- Determination of the percentage by weight of leaf-like, stem, boll, seed, and weed materials.
Main Results:
- Bract and leaf content increased as trash particle size decreased.
- Cotton seed coat fragment content decreased with smaller trash particle sizes.
- Weed materials constituted approximately 25% of the botanical waste.
Conclusions:
- Saw-type lint cleaning selectively removed stem trash but did not reduce leaf-like trash.
- Lint cleaning effectiveness is dependent on the type and particle size of the trash.
