The cotton knit fabric, renowned for its excellent water absorption, durability, and washability, ensures comfort throughout the changing seasons—keeping warm in winter without sacrificing breathability and providing exceptional coolness in summer. It is one of the preferred materials in the children's clothing market, highly favored by consumers. However, cotton knit fabric has relatively weak elasticity and a high shrinkage rate, and it tends to wrinkle easily, which is one of its physical characteristics that should be taken into consideration during use and care. In terms of color presentation, cotton knit fabric offers bright and rich colors with a complete color spectrum, providing ample design space for children's clothing, casual wear, underwear, and sportswear. While its excellent dyeing properties bring visual pleasure, specific processes are needed to enhance colorfastness. The fabric's outstanding moisture absorption and breathability are the core of its wearing comfort. Additionally, it has a soft hand feel and a natural sheen, presenting a simple yet elegant texture. During processing, we leverage its resistance to alkalis and acids, using strong alkali treatment to enhance fabric luster and achieve a mercerized effect, further elevating product quality. Cotton knit fabric also exhibits good lightfastness, but prolonged exposure to direct sunlight requires attention to the risks of fading and strength degradation. To address its tendency to wrinkle and lack of elasticity, we are continuously exploring innovative technologies to improve its physical properties while maintaining the fabric's natural advantages. Regarding the care of cotton fabrics, we remind users to protect against mildew and moths, as proper storage and care are essential for extending the fabric's lifespan, despite cotton's inherent insect resistance.
