Problems solved by technology

However, the air permeability and moisture dissipation of these pillow core materials are relatively poor, and the sweat and water vapor produced by the human body during sleep cannot be discharged in time, which makes the human body feel stuffy and hot, and the quality of sleep is affected. Long-term use will cause the pillow to breed mites and Other fungi that cause damage to the human face, neck, and scalp
At the same time, the traditional memory foam is easy to tear and yellow, which makes the service life of the memory foam material drop significantly.

Abstract

The invention provides a loofah sponge inflatable sponge. The loofah sponge inflatable sponge is prepared from 1-15 parts of loofah sponge fiber, 10-25 parts of first polyether polyol, 40-60 parts of second polyether polyol, 20-30 parts of third polyether polyol, 45-60 parts of modified MDI and the like. The loofah sponge fiber is one or more of natural loofah sponge fiber, NaOH-H2O2 modified loofah sponge fiber, NaOH-CH3COOH modified loofah sponge fiber and NaOH-CO(NH2)2 modified loofah sponge fiber. The invention further provides a preparation method and application of the loofah sponge flatulence sponge. Meanwhile, the invention further provides a loofah sponge inflatable sponge pillow. Natural or modified loofah sponge fibers are mixed with polyether polyol and the like, and the loofah sponge inflatable sponge is prepared through a polyurethane slow-rebound foaming technology; and the material is used as a pillow inner material and has the advantages of being antibacterial, capable of helping sleep, resistant to tear, capable of dissipating moisture, breathable, resistant to yellowing and the like.

Description

technical field [0001] The invention relates to the field of bedding, in particular to a loofah flatulence sponge, its preparation and application, and a pillow. Background technique [0002] Sleep is the guarantee for the recovery of human energy and physical strength, while mattresses and pillows are the supporting platform for human sleep, which are directly related to the quality of human sleep. [0003] At present, most common pillows on the market use memory foam, latex, vacuum cotton, buckwheat husk, tea, lavender, cassia seeds, etc. as pillow core (filling) materials. Among them, memory foam and latex pillows occupy a larger market share. However, the air permeability and moisture dissipation of these pillow core materials are relatively poor, and the sweat and water vapor produced by the human body during sleep cannot be discharged in time, which makes the human body feel stuffy and hot, and the quality of sleep is affected. Long-term use will cause the pillow to br...
