Implications of Surface Chemistry on Cotton Fiber Processing
Cotton Fiber Processing Implications of Surface Chemistry
2008/5/16
Increasing speeds of cotton yarn production in the textile mill have made it necessary to development complementary methods to traditional measurements of physical fiber properties, such as length and...
Increasing Picker Efficiency by Using a Boll Saver Attachment
Increasing Picker Efficiency Saver Attachment
2008/5/16
Cotton harvest losses due to delayed picking after defoliation and out-of-adjustment pickers can be as high as 20%. This study was conducted to determine the effects of a new harvest aid attachment, c...
Pilot Study to Examine the Relationship between AFIS Fiber Properties and White Speck Occurrence
White Speck Occurrence AFIS Fiber Properties
2008/5/16
Cotton containing dead and/or immature fibers is a major concern in the dyeing and finishing of textile products. In an un-dyed state, entangled fiber clusters are generically classified as neps. It i...
Mitigation of Whitefly Honeydew Levels on Cotton Lint via Thermal and Citric Acid Treatment
Cotton Mitigation of Whitefly Honeydew Levels
2008/5/15
Contamination of cotton lint by insect honeydew can interfere with carding, roving, and spinning processes at the mill, and thus presents a major concern for the textile industry. Several methods exis...
Cotton always has trash associated with its fibers, which is known to affect processing efficiency. Rotor spinning is more sensitive to trash levels in cotton compared with ring spinning, the other ma...
Microbial Census and Evidence for a Direct Temporal Effect of Bale Moisture with Color Grade during Six Months of Storage
Evidence Microbial Census
2008/5/15
As part of an ongoing investigation, a corroborative study was conducted to follow changes in fiber quality, moisture content, and microbial population in cotton bales with high moisture contents for ...
Microbial Activity of Stored Cotton Bales with Ambient and Moderate Moisture Levels
Stored Cotton Microbial Activity
2008/5/15
Studies on moisture augmentation of cotton bales have shown that excessive amounts of water lead to a reduction in fiber quality. To identify an acceptable range of cotton bale moistures that could be...
Size Lubrication Methods for Air-Jet-Spun and Ring-Spun Warp Yarns
Air-Jet-Spun Size Lubrication Methods
2008/5/14
No specific studies have been performed to determine benefits of lubricants in size bath mixtures for air-jet-spun cotton (Gossypium hirsutum L.) yarns. This study focused on the effect of size concen...
Survey of Seed-cotton and Lint Cleaning Equipment in U.S. Roller Gins
Lint Cleaning Equipment Seed-cotton
2008/5/14
Pima cotton is roller ginned to minimize damage to the fiber. The U.S. roller ginning industry has changed over the years. Since 1989, the majority of gins have shifted from Arizona to California. The...
The Effect of Harvesting Procedures on Fiber and Yarn Quality of Ultra-Narrow-Row Cotton
Fiber Harvesting Procedures
2008/5/14
The ultra-narrow-row (UNR) cotton system is defined as planting a cotton field with closely spaced rows (typically less than 38.1 centimeters). Because this narrow-row spacing provides the potential f...
Reducing Soil Compaction of Tennessee Valley Soils in Conservation Tillage Systems
Tennessee Valley Soils Conservation Tillage Systems
2008/5/13
Inadequate rooting systems due to excessive soil compaction have prevented farmers in the Tennessee Valley region of northern Alabama from adopting conservation tillage systems. Cotton (Gossypium hirs...
Processing Sticky Cotton: Implication of Trehalulose in Residue Build-up
Implication of Trehalulose Processing Sticky Cotton
2008/5/13
Cottons (Gossypium hirsutum L.) contaminated with stickiness can cause multiple problems in the textile mills. Contaminants originate from physiological sugars coming from the plant itself and/or ento...
Relationships Between Micronaire, Fineness, and Maturity. Part I. Fundamentals
Maturity Fineness Micronaire
2008/5/12
Micronaire has been used as a substitute for assessing cotton (Gossypium hirsutum L.) fineness and maturity when these measures are not available. Variability in R2 between the paired fiber properties...
Relative Velocity, Density, and Temperature Effects on Cotton Moisture Transfer Rates
Density Relative Velocity
2008/5/12
Moisture control during cotton (Gossypium hirsutum L.) harvesting, storage, and processing is essential for producing a quality product. The objective of this study was to quantify the effects of rela...
Stability Comparisons Between Conventional And Near-Isogenic Transgenic Cotton Cultivars
Conventional Stability Comparisons
2008/5/9
