Influence of Harvesting and Gin Cleaning Practices on Southern High Plains Cotton Quality
Applied Engineering in Agriculture, 2012
Southern High Plains cotton has improved over the last ten years with regard to yield and fiber length and strength. In light of increased adoption of picker harvesting to preserve fiber quality and improve harvest productivity, ginning practices are needed which preserve fiber quality and maximize return to the producer. The objective of this work was to investigate the influence of harvest method, number of seed-cotton extractor cleaners (e.g. stick machines), and seed-cotton cleaning rate on foreign matter content, lint value, and fiber and yarn quality of cotton produced in the Southern High Plains. Compared to using only one stick machine, the use of two stick machines in the seed-cotton cleaning system removed more foreign material from both picker-and stripper-harvested cotton, but more foreign material was removed by the stick machines from stripper-harvested cotton because it had higher initial foreign matter content. Seed-cotton cleaning rate had no influence on stick machine cleaning performance for picked cotton but higher cleaning rates reduced stick machine cleaning performance for stripper-harvested cotton. Picker-harvested cotton exhibited improved HVI and AFIS fiber quality and higher bale values compared to stripper-harvested cotton. The use of two stick machines improved fiber color properties and reduced lint foreign matter content. Seed-cotton cleaning rate had a minimal effect on fiber quality and bale value was not influenced by the number of stick machines or seed-cotton cleaning rate. Total lint value, on a production area basis, was higher for stripper-harvested cotton after both lint cleaners compared to picker-harvested cotton due to yield differences. Yarn imperfections were reduced for ring spun yarn produced from picker-harvested cotton processed through one stick machine at the high cleaning rate. The findings of this work support a recommendation for using one stick machine in seed-cotton cleaning systems processing picker-harvested cotton and two stick machines in systems processing stripper-harvested cotton.

Beltwide Cotton Quality Before and After Lint Cleaning
Journal of Cotton Science
A two-year, commercial cotton gin sampling project was conducted during the 2005-06 and 2006-07 ginning seasons to assess the changes in upland cotton quality during the ginning process and throughout the ginning season across the entire cotton belt. This report summarizes the cotton quality information collected to establish a baseline for cotton quality before and after saw-type lint cleaning for future research efforts to address cotton short-fiber content and fiber entanglements (neps) that occur during processing. Fiber quality measurements of ginned lint sampled before and after saw-type lint cleaning followed expected trends in that lint cleaning improved color grades, reduced foreign matter content, reduced fiber length and length uniformity, and increased short-fiber content and neps. Fiber quality measurements before and after lint cleaning summarized by cotton growing region showed similar trends to those summarized across the cotton belt. Differences in fiber quality mea...
Effects of harvesting and ginning practices on Southern High Plains cotton: textile quality
Textile Research Journal, 2019
The impact of the harvesting method, as well as the ginning method (saw or high-speed roller ginning), on textile quality was studied over three years of cotton production in the Southern High Plains. The Southern High Plains region is the largest cotton production area of the USA. The Southern High Plains and the Texas Gulf Coast are the only areas of the USA where brush-roll stripper harvesting is common, alongside traditional spindle picker machine harvesting. Different harvesting methods lead to differences in micronaire, maturity, length distribution, color and non-lint content within the bale. Ginning differences were primarily found to be length and length distribution related. Lint was processed into rotor-spun, carded ring-spun and combed ring-spun medium count yarns to determine the impacts of harvesting and ginning methods on textile product quality. Rotor spinning produced comparable quality yarns regardless of harvest or ginning method, while carded ring-spun yarns show...
ECONOMICS & MARKETING Costs Associated with Alternative Cotton Stripper-Harvesting Systems in Texas
2000
Cotton has consistently ranked as a leading cash crop in Texas. In 1997, Texas led the USA in the production of upland cotton and ranked second in the nation in the production of American pima cotton. Currently, 85% of the harvested cotton in Texas is stripper harvested. The acreage of cotton produced in Texas leaves producers with questions concerning the most cost-effective method of cotton harvesting in individual situations. The objective of this study was to determine the least costly harvesting system for strippers with and without bur extractors, by size of cotton operation in Texas. Data regarding investment costs, maintenance costs, and performance rates for four-, six-, and eight-row cotton strippers with and without bur extractors were collected from cotton producers, harvesting equipment owners, equipment dealers, and custom cotton harvesters between June and September 1999. The fixed cost, variable cost, total cost, and average cost of owning and operating each type and...
Modification and Performance Characteristics of a New Prototype for Cleaning Seed Cotton
The present investigation was conducted in October, 2007 at the Rice Mechanization Center, Meet El-Deeba, Kafr El-Sheikh governorate. The modified prototype was fabricated at a small workshop in Kafr El-Sheikh city. The experimental results revealed that the seed cotton extractor (prototype) performance after modification was better than that before. Seed cotton waste was minimized by 14 % and 32.58 % for the prototype before and after modification, respectively. Also, cotton trash content was reduced by 8.87 and 35.75 % for the prototype before and after modification, respectively. Its productivity was increased by 92.19 % and 109.15 % before and after modification, respectively. Also, the prototype productivity was increased by 28.24 % when the feed rate was increased from 0.60 to 0.75 Mg/h. At all the investigated feed rates, the modified prototype had higher values of cleaning efficiency. The increment in cleaning efficiency was of 21.22 % by raising feed rate from 0.60 to 0.75Mg/h. The prototype energy requirements were minimized by 42.59 and 47.02 % before and after modification, respectively. Cotton moisture content was reduced by 31.80 % when the drying air temperature increased by 11.63 %. Total cost requirements for the modified prototype were slightly smaller by 0.66 %. Whereas, criterion function cost was smaller for the modified prototype by 16.77 % than before modification as seed cotton losses were effectively minimized after modification. The characteristics of cotton fiber quality were highly enhanced and strongly influenced by the investigated variables for the modified prototype than before modification.

2235 BELTWIDE COTTON QUALITY STUDY
2000
A two year, belt-wide commercial cotton gin sampling project was initiated in 2005 for the 2005-06 and 2006-07 ginning seasons to assess the changes in upland cotton quality throughout the ginning process and the ginning season with the ultimate goal of identifying areas where improvements can be made in preservation of fiber quality. This report discusses analysis of the first year data. Overall fiber properties after one stage of lint cleaning were typical of U.S. cotton. In order to compare quality of fiber in seed-cotton samples with ginned lint samples from a commercial gin, hand ginning to lab ginning relationships were developed and used to correct the fiber quality data for lab ginned seed-cotton samples to near pre-ginning values. Trash content analyses showed that cleaning machines typically reduced foreign matter content per lint basis from as high as 50% at the module to about 4% at the lint slide. Short fiber content (SFC) values after ginning were double those at the feeder and increased at a lesser rate with lint cleaning. Nep counts were nearly tripled by the gin stand, then increased steadily as the lint passed through the first and second stage of lint cleaning, but the increases associated with the lint cleaners was much less than that at the gin stand. Length measurements also decreased due to processing. More in-depth data analyses will continue after the 2 nd year data are complete. This future work will focus on within-ginning process changes, changes as the ginning season progressed, interactions among fiber properties (i.e. SFC and micronaire or neps and length), and effects of cleaning.
Cotton waste recycling: Quantitative and qualitative assessment
Resources Conservation and Recycling, 2008
The waste produced in a cotton textile mill is an important factor in determining the operating cost and therefore in influencing mill profits. In this paper, we examine the waste percentage and the good fibre fraction for two cleaning machines and a card. The cleaning behaviour in spinning preparation, of each waste, is predicted by determining the trash content and the preparatory processing. The quality of recovered fibres is discussed and compared to other virgin cotton. In order to appreciate these fibres, we study the effect of cotton wastes on the rotor yarn quality. The results indicate that generated wastes contain about 50% good fibre. This secondary raw material showed good cleanability and characteristics; therefore it can be blended in a proportion between 15 and 25% without hardly noticeable changes in rotor yarn quality.
