Abstract

The invention discloses a preparation method of pearl wool particles for a pillow inner material, and the method comprises the following steps: (1) uniformly mixing a sodium silicate solution and a sodium bicarbonate solution to obtain a silica gel sol system, and adding polyvinyl alcohol, tricalcium phosphate, the sodium silicate solution and the sodium bicarbonate solution to obtain a silica gelgel system; (2) adding a cobalt naphthenate and lanthanum nitrate solution into the silica gel gel system, and reacting to obtain an antibacterial agent; and (3) adding low-density high-pressure polyethylene, talcum powder and polylactic resin into an extruder, pumping butane, an antibacterial agent, carvacrol and monoglyceride into the extruder, reacting to form a foaming body, extruding, drawing and cutting the foaming body to obtain pearl wool, and treating the pearl wool by adopting a home textile pearl wool machine to obtain the pearl wool particles for the pillow inner material. The prepared pillow inner material is excellent in softness, resistant to dirt and particularly remarkable in antibacterial effect, and does not mildew after being used for a long time.

Description

technical field [0001] The invention relates to the technical field of pillow core materials, in particular to a method for preparing pearl cotton particles for pillow core materials. Background technique [0002] The pillow core is the filling material of the pillow. With the development of science and technology and the continuous emergence of new materials, the materials of pillow cores on the market are becoming more and more abundant: from traditional buckwheat husk, traditional Chinese medicine, tea, to latex, memory foam, pearl cotton, porous vacuum cotton, etc. . [0003] Pearl cotton is widely used in pillow core materials because of its excellent softness and cushioning properties, low thermal conductivity, excellent heat insulation, and light weight. But existing common pearl cotton, its antibacterial performance is relatively poor, after using for a long time, the phenomenon of mildew can be produced inside it, has had a strong impact on the quality of pillowca...
