Abstract
Description
Technical Field
[0001] The invention relates to the technical field of furniture products, in particular to a memory foam pillow that is resistant to water washing and machine washing. Background Art
[0002] The slow rebound memory pillow, also called the memory foam memory pillow, can reduce the pressure on the head and neck, that is, it absorbs the pressure of the human body. When the human body touches the material, the material will sense the temperature of the human body and gradually become softer, while absorbing the pressure of the human body, thereby adjusting the human body to the most comfortable posture.
[0003] What is shown on the mattress and pillow is that when a person lies on them, the spine is in a natural S-shaped physiological curvature when lying on the back, and the spine does not bend sideways when lying on the side. At the same time, the mattress and pillow have no pressure points on the human body.
[0004] However, traditional memory foam pillows have a serious flaw, which is that they are usually not washable. Due to the special structure and material characteristics of memory foam, washing may cause damage to its internal structure, such as collapse, loss of elasticity, and may also breed bacteria and produce odor, which not only affects the life of the pillow, but also poses a potential threat to the health of the user.
[0005] After long-term use, users can only choose to replace pillows because they cannot be thoroughly cleaned, resulting in waste of resources and increased economic costs. Summary of the invention
[0006] The technical problem to be solved by the present invention is to overcome the above technical defects and provide a water-washable and machine-washable memory foam pillow that can be washed or machine-washed to facilitate cleaning of the pillow.
[0007] To solve the above technical problems, the technical solution provided by the present invention is: a memory foam pillow that is washable and machine washable, comprising a pillow core, a waterproof film is provided on the outside of the pillow core, a pillowcase is provided on the outside of the waterproof film, and a connecting structure layer is provided between the waterproof film and the pillow core.
[0008] Preferably, the connecting structure layer is made of elastic polyester fibers woven in a mesh shape.
[0009] Preferably, the waterproof membrane is made of nanofiber membrane material.
[0010] Preferably, the components in the pillow core include an amine catalyst, a tin catalyst, a water foaming agent, an auxiliary foaming agent, a cross-linking agent, a uniform foaming agent and modified MDI.
[0011] Preferably, the pillowcase is made of any one of cotton, polyester, linen, and bamboo fiber materials, or a combination of two of them.
[0012] Preferably, based on 100 parts by total weight of polyether polyol, 0.1-0.8 parts of amine catalyst, 0.08 parts of tin catalyst, 1.5-3 parts of water foaming agent, 1-10 parts of auxiliary foaming agent, 0.1-1 parts of cross-linking agent, 1-3 parts of uniform foaming agent and 44 parts of modified MDI, the tin catalyst is organic tin, the mold temperature after mixing is 55°C, the demolding time is 6 minutes, and the density is 60.
[0013] The advantages of the present invention compared with the prior art are: in the present invention, by improving the structure of the pillow core of the existing memory foam pillow, by adding a hydrophobic polymer without affecting the slow rebound characteristics of the memory foam, the interaction between water molecules and the main structural components inside the memory foam is effectively prevented; at the same time, the cross-linking agent enhances the structural stability of the memory foam after it comes into contact with water, so that it can maintain its shape and elasticity during washing; in the present invention, an additional waterproof layer made of a nanofiber membrane is added to reduce the penetration of dirt during use, and at the same time cooperate with the connecting structure layer to prevent the pillow core and pillowcase from moving during washing.
