Problems solved by technology

In order to protect the normal physiological curvature of the neck and maintain normal physiological activities when people sleep, pillows must be used when sleeping. Pillows are generally composed of pillow core and pillowcase. Some pillows mainly consider the impact of the filling in the pillow on the human body. Influences from other aspects, and then to promote human health, such as medicinal pillows filled with traditional Chinese medicine, tea pillows filled with tea leaves, incense pillows filled with petals, and physiotherapy pillows filled with magnetic materials, etc., are often found on the market. The most widely circulated pillows are traditional pillows filled with cotton and other fibers. There are also some health pillows that use memory foam and other structures. However, these pillows are easy to deform after a period of use, which affects health and has poor air permeability. It is easy to breed bacteria, causing facial skin problems, and even the pillow core cannot be cleaned. Although some can be cleaned, they are prone to fiber clumping and pillow collapse.

Abstract

The invention discloses a core-to-core pillow. The pillow comprises a pillowcase and a pillow inner which is arranged in the pillowcase, wherein the pillow inner comprises a filling sandwich layer which has a three-dimensional network shape plastic wire, and padding layers which cover the upper surface and the lower surface of the filling sandwich layer. The invention further discloses a producing method of the core-to-core pillow. The producing method comprises multiple procedures. The obtained pillow is good in permeability, the sandwich layer is good in supporting performance, and the pillow is full in appearance; meanwhile, the core-to-core pillow has the advantages that after long term use, the pillow is not prone to collapse, and the pillow can bring a user a comfortable head sleep environment; besides, the pillow is washable, through hot-pressing bonding and molding of flexible cushion layer fiber and a three-dimensional net shape filament pore surface which is in contact with the flexible cushion layer fiber, it is guaranteed that the situations of fiber clotting, and pillow collapse caused by the displacement of the fiber in the washing process do not occur.

Description

technical field [0001] The invention relates to the technical field of household articles, in particular to a core-in-core pillow and a manufacturing method thereof. Background technique [0002] A pillow is a sleeping tool. It is generally believed that pillows are fillers that people adopt for sleeping comfort. From the understanding of modern medical research, the spine of the human body is a straight line when viewed from the front, but it has three physiological curved curves when viewed from the side. In order to protect the normal physiological curvature of the neck and maintain normal physiological activities when people sleep, pillows must be used when sleeping. Pillows are generally composed of pillow core and pillowcase. Some pillows mainly consider the impact of the filling in the pillow on the human body. Influences from other aspects, and then to promote human health, such as medicinal pillows filled with traditional Chinese medicine, tea pillows filled with ...
