Embodiment Construction

[0023] The following examples further describe the present invention, but the examples are only for illustrating the present invention rather than limiting the present invention.

[0024] like figure 1 The polymer elastic air permeable pillow 100 shown is made of fibers 110 extruded from several polymer materials which are melted into a flat and long fixed shape. The interior of the pillow 100 is a spatial network structure. The fiber 110 is a fiber with a stable crimped shape, which is extruded from polymer materials such as LDPE, HDPE, LLDPE, EVA, PP, and PE. The diameter of fiber 110 is 0.5-3mm, and the density of pillow core 100 is 40-120kg / m 3 . Fiber 110 may be a solid core fiber or a hollow core fiber.

[0025] see Figure 5 , the preparation process of the pillow core 100 is as follows:

[0026] 1. Add the polymer material into the high-power screw extruder 200, pass through the die head 300 installed on the screw extruder 200, and several extrusion holes 311 on t...

Abstract

The invention discloses a high molecular elastic ventilated pillow inner which is formed into a prolate fixed shape by a plurality of fibers extruded by high molecular materials through melting per se. The inside of the pillow inner is of a space reticulate structure. The high molecular materials are LDPE (Low-Density Polyethylene), HDPE (High-Density Polyethylene), LLDPE (Linear low density polyethylene), EVA (Ethylene-Vinyl Acetate copolymer), PP (Propane Polymer), PE (Poly Ethylene) and the like. The high molecular elastic ventilated pillow inner is of a three-dimensional elastic structure formed by high molecule polymerization, and the thousands of curly fibers provide excellent elasticity. Because the elasticity comes from the molecular materials per se, long-lasting elasticity is available (the elasticity is proven by 250,000 compression tests); and because the high molecular elastic ventilated pillow inner is formed by melting per se and is not adhered by using gluewater, the high molecular elastic ventilated pillow inner has favorable soundness of tension and fatigue resistance; because the inside of the pillow inner is of the space reticulate structure, the high molecular elastic ventilated pillow inner has favorable air permeability. The invention also discloses a preparation method of the pillow inner.

Description

technical field [0001] The invention relates to a pillow core and a preparation method thereof, in particular to a polymer elastic breathable pillow core and a preparation method thereof. Background technique [0002] Pillows of the prior art, its pillow core is filled with natural materials such as kapok, down, Chinese herbal medicine, because its shape cannot be finalized, causes the cervical spine to hang in the air when sleeping, and cannot be well protected, making cervical spondylosis a common disease. Later, some people in the industry began to use foamed plastics, such as latex, to make pillow cores. Because they are well shaped and have a protective effect on the cervical spine, they are very popular among people. However, this kind of latex pillow has a disadvantage of poor air permeability, and it is difficult to be hot when used in summer. Although the industry has air holes on this type of latex pillow core, due to the limited number of air holes, the ventilati...
