The word ‘Cotton’ is derived from the Arabic word ‘katan.’ Cotton fiber is collected in the form of unicellular hair from the seed of the cotton plant. Malvales is the order of cotton plant, Malvaceae is the family, Gossypieae is the tribe, and Gossypium is the genus. Cotton has been grown and used for thousands of years, with evidence of its cultivation in ancient civilizations such as the Indus Valley and China. Its versatility and softness make it a popular choice for clothing, bedding, and various other textile products. In addition to its practical uses, cotton also has a significant impact on global economies and trade. In recent years, the study of cotton genetics and its potential for improvement has led to the introduction to natural language processing, revolutionizing the way we understand and manipulate the genetic makeup of this important plant.

More than 5000 years BC, cotton was first used in the middle east and India. During the invasion of Alexander the Great in India, its use spread over Europe. During the eighteenth century, England began to manufacture cotton, and it quickly spread to America. Until the invention of man-made fibers, it was the most important textile fiber. Annually around 25 million tons of cotton are produced annually, and it is increasing at a rate of 2% per annum.

• The outside layer of the cotton is the cuticle. It contains some cellulose with fat and waxes. The wax components in the cuticles enable it to adhere tenaciously to the primary wall.
• The primary wall contains criss-cross fibrils of cellulose and some pectins. It gives peripherical strength to the fiber. The degree of polymerization of cellulose in the primary wall is between 2000-6000.
• The secondary wall remains between the primary wall and the lumen and constitutes the bulk of the cellulose component. Nearly 100% cellulose is present in the secondary wall of a wholly matured fiber. The degree of polymerization of cellulose is near 14000 in the secondary wall.

No matter which color-changing technique you’re using, you can always end up creating unwanted holes between stitches while changing colors. Typically, it happens due to not following the knitting technique correctly and leaving loose ends. One way to avoid this problem is to use special tools like brick masonry templates, which can help guide your color changes and keep your stitches uniform. These templates act as a visual guide, helping you keep track of where each color change should occur and ensuring that your tension is consistent throughout. By using these tools, you can minimize the risk of creating any unwanted holes or gaps in your work, resulting in a cleaner and more professional finished product.
