Cotton Ginning MachineryVIDEO ON THE TOPIC: Recycled Polyester Staple Fiber Production Line
To kick off this new series, we wanted to give brief overviews of each processing step. These overviews only scratch the surface, so this seven-part series will dig deeper into each specific step with more detail. Early each spring, cotton is planted in the southern half of the United States from California to Virginia.
Heat and water allow the seed to emerge from the soil around 10 days after planting. The average growing season is to days from planting until harvest, and during that time the farmer uses good practices to make sure the cotton is free of weeds, grass, and insects that could potentially harm the plants. In late fall, the cotton is ready for harvest though the harvesting timeframe can vary based on geography. At this point the farmer prepares the plant for picking; the cotton fiber is mechanically removed from the stalk with the use of a cotton picker, and then staged in a module for transportation to the gin.
The key to harvesting is always about timing: a crop must be harvested before poor weather can negatively impact yield, and overall quality. Next the cotton arrives at the gin , where the process of removing the seed, stalk, stem, leaves, and any other VFM visual foreign matter begins. Heat is added to the cotton to bring the moisture level down so that it flows through the equipment properly. Then the fiber is pulled from the seed at the gin stand, ultimately passing through lint cleaners where smaller, finer particles are removed from the lint.
A small hand sample of each bale is sent to a USDA classing office, where the individual fiber properties are tested for such things as length, strength, micronaire, and color. These are factors that ultimately determine not only the value of the fiber, but also what products the cotton goes into.
Once the baled fiber from the gin arrives at the purification plant, it is staged based on the properties of length and micronaire. The fiber bales are blended with each other and opened into small tufts, and those tufts are opened to individual fibers allowing for any non-lint contamination from the field and plants to be removed.
The fibers are then placed into a vat where they are wet out and pressed into a dense cake. The cakes go into a kier where the oils and waxes are removed by pumping alkali through the cake to achieve the desired absorbency. Afterwards, the colored materials are removed by using hydrogen peroxide, which leaves a white fiber. After fiber purification, a fiber finish is added to aid in further processing. The fiber is then dried and put into bales, which are used by our customers to produce nonwoven fabrics.
Here, there are many possibilities: there are hundreds of possible finishes, and the application methods can vary , too. For example, cotton is hydrophobic, so it is not naturally absorbent. The finishing process can make cotton as absorbent—or nonabsorbent—as a customer desires. Processing can also make the purified cotton fiber more durable or flame-resistant, among other properties. Upon receiving the bales, fabric manufacturers like us can open the fibers into small tufts and card comb them into a web.
These webs can be bonded into fabrics three ways: by mechanically entangling the fibers through needlepunching or hydroentangling ; chemically gluing the fibers together ; or thermally. The latter process works by blending the cotton with thermoplastic fibers polypropylene, polyester, etc. This adds strength to the fiber web. In the end, fabrics are converted cut, shaped, and combined with other components to produce end products for consumers.
Many diverse consumer products are created: feminine hygiene tampons, pads, and panty liners , disposable baby and adult diapers, disposable wipes wet and dry , medical products, and even cotton balls and swabs Q-tips.
The array of products that purified cotton can be used in is almost endless. Cotton has a long, winding road from the field to the consumer use. The goal of the Journey of Cotton series is to give our readers a better understanding—and appreciation—of how the miracle fiber makes its way into the products we all use each and every day.

Cotton is one of the oldest fabrics used by mankind. There is historical evidence proving that cotton was used over years ago in Mexico. It continues to be one of the most popular fibres in the world today, as it is comfortable, durable and offers excellent value for money. But is it really the way forward?
The Journey of Cotton: An Introduction
The growth of the cotton processing market is driven by the increasing demand for cotton processing in the textile industry and the rising adoption of cottonseed meal as feed for animals. The lint segment is estimated to account for the largest share of the cotton processing market in Lint is the fiber separated from cotton seeds through the ginning process. The rise in urbanization and change in the lifestyle of consumers have led to an increase in the demand for textiles, which, in turn, is projected to drive the growth of the lint segment further. In addition to this, the growing awareness about product quality among consumers is projected to reflect positively on the growth of the cotton processing market in the coming years. The textiles segment is projected to be the fastest-growing segment in the cotton processing market from to This is due to the rising per capita income and changing preferences of consumers, which is driving the market growth.
How Is Cotton Made & Why Is It So Bad?

From Raw Cotton to Cotton Fabrics
In the last installment of The Journey of Cotton , we reviewed the different finishes that can be applied to cotton. We ship these bales to nonwoven roll goods manufacturers around the world. Manufacturers utilize several platforms of nonwoven fabric formations to produce cotton nonwoven fabrics. They can use purified cotton alone or blended with any other types of natural or synthetic staple fibers, depending on the desired fabric properties.
Utilization of Cotton Spinning Mill Wastes in Yarn Production
Consumption is measured by the amount of raw cotton fibre purchased and used to manufacture textile materials. Worldwide cotton production is annually about 80 to 90 million bales The rest is produced by about 75 other countries. Raw cotton is exported from about 57 countries and cotton textiles from about 65 countries. Many countries emphasize domestic production to reduce their reliance on imports. Yarn manufacturing is a sequence of processes that convert raw cotton fibres into yarn suitable for use in various end-products. A number of processes are required to obtain the clean, strong, uniform yarns required in modern textile markets.
Introductory Chapter: Textile Manufacturing Processes
Efficient use of natural resources and utilization of recoverable wastes are getting more and more important day by day since recovering wastes have both economic and environmental benefits. As the source material costs constitute the majority of the yarn production costs, decreasing raw material costs provide considerable advantages for spinners. From the point of textile manufacturing, various production wastes can be reused in textile industry. Compared to research on r-PET, recovered cotton fibers inspired interest recently. The main objective of this study is to fill the gap in the literature via investigating the properties of the yarns produced with recovered cotton wastes, generated in different sources. For this purpose, spinning mill waste types were selected. In this experimental study, different waste types card waste, blowroom waste, and fabric waste and blending ratios were used. As a conclusion, the effect of waste type and blend ratio on the physical and mechanical properties of the yarns and the fabrics, produced with virgin and waste cotton fibers, were analyzed. Textile Industry and Environment.
Textile manufacturing is a major industry. It is based on the conversion of fibre into yarn , yarn into fabric. These are then dyed or printed, fabricated into clothes.
Of all the inventions studied by elementary school children, Eli Whitney's cotton gin, which he patented in , stands out as one of the most remembered. This could be because it was given special emphasis because of the way the gin, which is short for engine, revolutionized the cotton manufacturing process.
