Description

Ice silk cool sense antibacterial anti-mite pillow and preparation process thereof Technical Field The invention belongs to the technical field of articles for daily use, and particularly relates to an ice silk cool sense antibacterial anti-mite pillow and a preparation process thereof. Background Pillows are increasingly valued by consumers as daily household necessities for comfort, health and functionality. The ice silk material is widely applied to functional pillow products due to the characteristics of smoothness, ventilation and cool feeling, and various products such as ice silk cool feeling pillow, antibacterial pillow, anti-mite pillow and the like are already appeared on the market. However, the existing products have the following limitations that firstly, the functional synergy is poor, the cooling effect is mostly dependent on physical heat-conducting fibers or cooling auxiliary agents, the antibacterial and anti-mite functions are realized by means of after-finishing auxiliary agents, the two are easy to influence each other in processing and use, for example, the cooling treatment can influence fixation of an antibacterial agent to cause rapid decay of the functions after multiple times of washing, secondly, the long-acting performance is insufficient, the existing antibacterial and anti-mite technologies mostly adopt physical adsorption or simple coating modes, the durability is poor, the functions are obviously reduced after multiple times of washing or long-term use, in addition, the safety and the comfort are difficult to be compatible, partial antibacterial and anti-mite agents have chemical residues, the stimulation to human skin is possibly generated, meanwhile, the use amount of the auxiliary agents is increased for enhancing the functional effect or thicker coatings are adopted, the handfeel of the fabrics is hard, the air permeability is reduced, and the natural comfort of ice silk materials is influenced. Therefore, there is an urgent need to develop a multifunctional pillow which has lasting cool feel, high-efficiency antibacterial and anti-mite properties, is safe, environment-friendly, comfortable and durable, and meets the requirements of high-quality healthy sleep. Disclosure of Invention Aiming at the defects of the prior art, the invention provides an ice silk cool sense antibacterial anti-mite pillow and a preparation process thereof.
