Preparation process of 3D overlapping curve memory cotton

Abstract

The invention discloses a preparation process of 3D overlapping curve memory cotton. The 3D overlapping curve memory cotton is sequentially provided with a supporting layer, a comfortable layer and a3D breathable layer from bottom to top; the preparation process comprises the following steps that 1) a foaming mold is made according to the specific shape and size of a target product; 2) memory cotton slices are cut into 3D overlapping curve memory cotton slices through a machine to obtain the 3D breathable layer; 3) the comfortable layer is compounded on the 3D breathable layer through a bonding agent to form a first structure layer; 4) a mixed material of the supporting layer is prepared, and the first structural layer is put into the preheated foaming mold; and 5) the mixed material is injected into the foaming mold, and the 3D overlapping curve memory cotton can be obtained after the mixed material is cooled and formed. According to the process, the supporting layer takes a fast-resilience supporting cotton as a bottom-layer cotton core, deformation is not prone to occur, the supporting layer conforms to a human body curve, can relieve nerve compression, and is beneficial to blood circulation; the comfortable layer adopts a common slow-resilience memory cotton, and the comfortable and breathable performance is achieved; and a 3D overlapping curve memory cotton pillow core has the advantages that the supporting performance and the comfort are achieved, and the skin-friendly and breathable effects are both achieved.

Description

technical field [0001] The invention relates to the field of home textile products, in particular to a preparation process of 3D mesh memory cotton. Background technique [0002] Existing memory foam products are all molded by one-time foaming with molds, resulting in very single characteristics such as density, hand feeling, softness and hardness of foamed memory foam products, which cannot meet the needs of human body curves. [0003] According to ergonomics, the support required by each part of the human body is completely different. Using disposable foamed memory foam products for a long time will compress the human nerves and blood vessels, causing body pain. [0004] The cotton core technology of memory foam products on the market is generally divided into two categories: one is cutting and forming, which is made of super-large memory foam blocks, and the cotton cores are cut out by cutting machines according to CAD size drawings, and then cut and formed. The shape of...

[0002] Existing memory foam products use molds for one-time foam molding, resulting in very single characteristics such as density, hand feeling, softness and hardness of foamed memory foam products, which cannot meet the needs of human body curves

[0003] According to ergonomics, the support required by each part of the human body is completely different. Long-term use of disposable foam-molded memory foam products will compress the human nerves and blood vessels, causing body pain

[0004] The cotton core technology of memory foam products on the market is generally divided into two categories: one is cutting and forming, which is made of super-large memory foam blocks, and the cotton cores are cut out by cutting machines according to CAD size drawings, and then cut and formed. The shape of the cotton core is simple, the surface is rough, and the air permeability is good; the other type is foam molding. The surface of the cotton core is smooth, the shape is rich, the air permeability is poor, the hand feeling is single, and the effect of comfort and support is not good. Supporting cotton), because in the process of using memory foam products, the corresponding support of each part of the human body is different, and the support of the foamed memory foam core with a single touch is the same, so it is easy to deform during use, and it will be used for a long time Cotton wicks will compress the nerves and blood vessels of the human body, causing body aches and even cervical spine diseases; there is a problem of heat accumulation and airtightness. Although some cotton wicks use perforated methods to solve the problem of air permeability, the perforated cotton wicks The method can not alleviate the problem of heat accumulation and airtightness
