Why was cotton so important in the 1800s?
Cotton was one of the world’s first luxury commodities, after sugar and tobacco, and was also the commodity whose production most dramatically turned millions of black human beings in the United States themselves into commodities. Cotton became the first mass consumer commodity.

How is scouring done?
Scouring is the first process carried out with or without chemicals, at room temperature or at suitable higher temperatures with the addition of suitable wetting agents, alkali and so on. Scouring removes all the waxes, pectins and makes the textile material hydrophilic or water absorbent. See also scouring wool.
Why is cotton mercerized?
Mercerisation is a textile finishing treatment for cellulose fabric and yarn, mainly cotton and flax, which improves dye uptake and tear strength, reduces fabric shrinkage, and imparts a silk-like luster.
What is the importance of cotton?
Cotton is one of the most important fiber and cash crop of India and plays a dominant role in the industrial and agricultural economy of the country. It provides the basic raw material (cotton fibre) to cotton textile industry.

Slaves in the Upper South became incredibly more valuable as commodities because of this demand for them in the Deep South.
How clothes are dyed?
Dye molecules are fixed to the fiber by absorption, diffusion, or bonding with temperature and time being key controlling factors. Acrylic fibers are dyed with basic dyes, while nylon and protein fibers such as wool and silk are dyed with acid dyes, and polyester yarn is dyed with disperse dyes.
What is the strength of cotton?
Tensile Strength: Cotton is moderately strong fiber. It has a tenacity of 3-5 gm/den. The strength is greatly affected by moisture; the wet strength of cotton is 20%, which is higher than dry strength.
How did the cotton industry affect slavery?
While it was true that the cotton gin reduced the labor of removing seeds, it did not reduce the need for slaves to grow and pick the cotton. In fact, the opposite occurred. Cotton growing became so profitable for the planters that it greatly increased their demand for both land and slave labor.
Is Cotton renewable?
Cotton is sustainable, renewable, and biodegradable, making it an excellent choice as an environmentally-friendly fiber throughout its entire product life cycle. Most chemical fibers are petroleum based, which means they come from nonrenewable resources.
Did cotton cause the Civil War?
Suddenly cotton became a lucrative crop and a major export for the South. However, because of this increased demand, many more slaves were needed to grow cotton and harvest the fields. Slave ownership became a fiery national issue and eventually led to the Civil War.
How does cotton impact the environment?
Soil, water, plants, animals and air are all part of what makes a dynamic and healthy cotton farming system. Unlike synthetics, cotton is biodegradable. It breaks down quickly in terrestrial and aquatic environments, and does not contribute to the microplastic pollution problem.
How do humans use cotton?
Cotton has been grown for food, fiber, and even fuel for over 6,000 years. You can find cotton in your clothes, sheets, and towels, but cotton is also used to make things like rope, U.S. currency, paper, cooking oil, animal feed, packaging, and biofuels. The benefits and versatility of cotton are numerous.
What is the purpose of sizing?
Sizing or size is a substance that is applied to, or incorporated into, other materials—especially papers and textiles—to act as a protective filler or glaze. Sizing is used in papermaking and textile manufacturing to change the absorption and wear characteristics of those materials.
Which dye is used for cotton?
Reactive dyes
What is desizing process?
Desizing is the process of removing the size material from warp yarns after a textile fabric is woven.
What is peach finish in fabric?
Peaching is a finishing process we use on the polycotton for our drill tops. After weaving, fabric is stretched while drying. This is when it takes on its stability. While drying the fabric is ‘peached’ by being brushed with abrasive rollers.
What is the purpose of cotton in nature?
All of the cotton plant is used, there is no waste. The fiber is the primary reason for growing cotton. But the seeds are used for animal feed and human use (cottonseed oil). The plant stalks are tilled back in the soil after harvesting.
What is Mercerization process?
Mercerization is a process in which textiles (typical- ly cotton) are treated with a caustic (NaOH) solution to improve properties such as fiber strength, shrink- age resistance, luster, and dye affinity. The caustic actually rearranges the cellulose molecules in the fiber to produce these changes.
What is cotton turned into?
The fabric usually used in the clothes we wear is produced through two processes: the “spinning process,” where raw cotton is turned into thread, and the “weaving process,” where the thread is woven into fabric.
Is Mercerization permanent?
Mercerization, in textiles, a chemical treatment applied to cotton fibres or fabrics to permanently impart a greater affinity for dyes and various chemical finishes. Higher-quality cotton goods are usually mercerized; cloths so treated take brighter, longer-lasting colours from less dye.
