Description

Technical Field

[0001] The invention belongs to the field of wood pulp insoles, in particular to a wood pulp insole with an anti-skid bottom surface and a manufacturing method thereof. Background Art

[0002] Existing disposable wood pulp insoles consist of upper and lower surface layers and a middle core layer. The middle core layer is made of a mixture of pulverized wood pulp fibers and two-component composite ES short fibers. The upper and lower surface layers are formed by pressing non-woven fabrics as surface layers to form a hard insole surface layer. These disposable wood pulp insoles offer advantages such as good flatness, high thermal insulation, ease of manufacture, and low cost. However, because the uniform convex and concave pattern is only applied to the upper surface, which contacts the foot, it can easily come loose during wear, poorly bonded to the lining of the sole, and prone to deformation. Disposable wood pulp insoles are particularly prone to being thin, wrinkling easily, and easily coming loose from the heel when walking, as well as deforming the insole. Summary of the Invention

[0003] In view of the problems existing in existing disposable wood pulp insoles, such as thin insoles, easy wrinkling, easy slipping out of the heels when walking, or deformation of the insoles, the purpose of the present invention is to provide a wood pulp insole with a non-slip bottom surface and a manufacturing method thereof.

[0004] The object of the present invention is achieved through the following technical solutions:

[0005] The wood pulp insole with anti-slip bottom surface of the present invention includes an upper surface layer, an intermediate core layer and a lower surface layer, the intermediate core layer is made of a mixture of crushed wood pulp fibers and crushed two-component composite ES short fibers, the upper surface of the upper surface layer that contacts the foot is provided with an upper surface convex-concave pattern; the lower surface of the lower surface layer is provided with a lower surface convex-concave pattern or lower surface anti-slip glue dots, and the lower surface convex-concave pattern or the lower surface anti-slip glue dots are in contact with the inner layer of the sole.

[0006] The wood pulp insole with anti-slip bottom surface of the present invention includes an upper surface layer, an intermediate core layer and a lower surface layer. The intermediate core layer is made of a mixture of crushed wood pulp fibers and crushed two-component composite ES short fibers. The upper surface of the upper surface layer that contacts the foot is provided with an upper surface convex and concave pattern; the lower surface of the lower surface layer is provided with an anti-slip rubber layer, and the anti-slip rubber layer is in contact with the inner layer of the sole.

[0007] Wherein: the anti-slip rubber layer is fixed to the lower surface layer by hot melting.

[0008] The mass percentage of the wood pulp fibers is 50% to 70%, and the mass percentage of the bicomponent composite ES short fibers is 30% to 50%.

[0009] The method for making a wood pulp insole with anti-slip bottom surface of the present invention is as follows: wood pulp fibers are crushed by a wood pulp crusher, two-component composite ES short fibers are crushed by a fiber quantitative machine, and the crushed wood pulp fibers and two-component composite ES short fibers are mixed to form the intermediate core layer; the upper surface layer and the lower surface layer are respectively pressed with non-woven fabrics as surface layers to form a hard insole surface layer, and then the intermediate core layer is sandwiched between the upper surface layer and the lower surface layer and fixed, an upper surface convex-concave pattern is pressed on the upper surface of the upper surface layer, a lower surface convex-concave pattern / lower surface anti-slip glue dots are pressed on the lower surface of the lower surface layer, or an anti-slip glue layer is added to the lower surface of the lower surface layer by hot melting.

[0010] The advantages and positive effects of the present invention are:

[0011] The present invention utilizes the lower surface convex and concave pattern / lower surface anti-skid adhesive dots or the lower surface anti-skid adhesive layer of the lower surface layer to increase the friction between the insole and the shoe, thereby preventing the thin wood pulp insole from moving and deforming in the shoe, fully meeting the requirements for flatness and comfort in the use of the insole, and achieving the degree of bonding between the thin wood pulp insole and the shoe; because of its increased friction and good bonding, it has good wearing comfort.
