Description

Technical Field

[0001] The present application relates to the technical field of fabrics, and in particular to a skin-friendly and antibacterial sleeping bag fabric and a preparation process thereof. Background Art

[0002] Infants and young children like to toss and kick while sleeping, and are likely to kick off the quilt. Infants and young children have low immunity and are prone to catching colds, so they usually choose sleeping bags to prevent them from kicking off the quilt and catching cold. Sleeping bags are generally made of pure cotton, but pure cotton fabrics are rough to the touch and easily deformed, and wrinkles increase the roughness. Infants and young children have delicate skin, and infants and young children are lively and active, so their skin often rubs against the fabric, causing many infants and young children to dislike pure cotton sleeping bags. In order to solve the problem that pure cotton fabrics are rough and easy to deform, the existing technology mainly uses finishing agents containing silicone oil, such as dimethyl silicone oil, amino silicone oil, etc. The principle is to use the good adsorption effect between silicone oil and cotton fibers, attach silicone oil to cotton fibers to fill the rough pores on the surface, and form a silicone oil film on the surface of cotton fibers. It has good lubricity and can improve the feel of cotton fabrics and improve wrinkle resistance to a certain extent. Generally, the amount of finishing agent is appropriately increased, which can improve the improvement degree to a certain extent. However, as the amount increases, the film layer becomes thicker, the improvement effect is not obvious, and it is easy to wash off; in addition, infants and young children have a fast metabolism, and the temperature and humidity in the sleeping bag are high, which is easy to cause bacteria to grow. Generally, a small amount of antibacterial material is added to the finishing agent to inhibit bacterial growth, but the external antibacterial agent is easy to wash off and cannot maintain a stable antibacterial effect. Moreover, as infants and young children grow and develop, their metabolism will gradually accelerate, and sleeping bags need to be frequently washed and dried. Therefore, it is urgent to develop a skin-friendly sleeping bag fabric with antibacterial effect. Summary of the invention
