Abstract

The invention specifically relates to an easy-to-color knitted fabric and a production method thereof. The knitted fabric comprises the following raw materials by mass percentage: 45-60% of natural cotton fibers, 30-40% of modified polyester fibers, and 10-10% of blended yarns. 25%, the obtained knitted fabric is soft to the touch, excellent in elasticity, moisture wicking, cool to the touch and strong in abrasion resistance. The knitted fabric adopts a one-time bath dyeing process, which makes the knitted fabric easy to dye, and the dyed knitted fabric has strong color fastness and high stability. The production method of the knitted fabric of the invention has the advantages of simple process, low production cost, low energy consumption and high production efficiency.

Description

technical field [0001] The invention relates to the technical field of knitted fabrics, in particular to an easy-to-color knitted fabric and a production method thereof. Background technique [0002] Cotton polyester knitted fabric not only has the comfort and softness of cotton fabric, but also retains the good wrinkle resistance and wear resistance of polyester. However, due to the difference in the content of cotton components and polyester components, the texture, comfort and durability of the fabrics are significantly different. The dyeing properties of polyester and cotton components are very different in the production process, the dyeing process is complex, time-consuming, and the dyeing effect is uneven. In the current cotton and polyester fabric dyeing process, the dispersing / direct, dispersing / reactive, and dispersing / reducing two-bath dip dyeing methods are commonly used, but the two-bath method has a long process, cumbersome process, water and energy consumptio...
