Pure cotton fabric is a textile made from the raw material of cotton and made of warp and weft yarns interwoven vertically and horizontally through a loom.
Cotton fiber has better hygroscopicity. Under normal conditions, the fiber can absorb moisture from the surrounding air, reaching a moisture content of 8-10%. Consequently, when in contact with human skin, it imparts a soft, but not stiff, sensation. If the humidity of cotton cloth increases and the surrounding temperature is higher, all the moisture contained in the fiber will evaporate and dissipate, keeping the fabric in a water-balance state and making people feel comfortable.
Cotton fiber exhibits a low thermal conductivity coefficient due to its poor conduction of heat and electricity. Additionally, cotton fiber is porous and possesses high elasticity, allowing a significant accumulation of air between the fibers. As air is a poor conductor of heat and electricity, pure cotton fiber textiles exhibit excellent moisture retention. Bedding made from pure cotton provides warmth to individuals.
Pure cotton textiles exhibit excellent heat resistance. Temperatures below 110°C only lead to the evaporation of water on the fabric without causing damage to the fibers. Consequently, pure cotton textiles can be used at room temperature. Processes such as washing, printing, and dyeing do not adversely affect the textiles, thereby enhancing their features of being washable and durable.
Cotton fiber exhibits greater resistance to alkalinity, remaining undamaged in alkaline solutions. This property is beneficial for cleaning, disinfecting, and removing impurities after use. Furthermore, pure cotton textiles can undergo dyeing, printing, and various technique processes, enabling the production of diverse varieties of cotton fabrics.
Cotton fiber is a natural fiber composed mainly of cellulose, along with small amounts of waxy substances, nitrogen-containing compounds, and pectin. Pure cotton textiles have undergone extensive testing and practical use, demonstrating no irritation or side effects upon contact with the skin. Moreover, long-term use is not only harmless but also beneficial to the human body.
Cotton can be divided into long fiber and short fiber. Short fiber is not strong enough. Although it is possible to make bedding with a high thread count, sheets made from this material will become old very quickly after being washed. Additionally, consumers often hear the term combed cotton, but what does combed mean? Generally, untreated cotton fiber contains many impurities, and the fiber is of different lengths. Therefore, a combing machine can be used to remove the impurities and comb the cotton fiber to spin a more uniform and fine-combed cotton yarn. During the combing process, about a quarter of the short fibers will be removed, which adds to the production cost; hence, the price of combed yarn bedding is relatively expensive.
