Abstract

The invention discloses an insole paper board for a shoe. The insole paper board comprises: by weight part, 50-80% of wood pulp or waste paper pulp, 5-15% of chemical fiber, 5-15% of cotton pulp, 2-8% of waterproof agents, 2-8% of wet strength agents and 10-30% of rubber latex. Waste cotton fiber and waste paper are selected as fiber raw materials, and therefore the problem of recycling of materials is solved fundamentally. The waste cotton is used for increasing the length of the fiber, the devillicate brooming degree of the fiber is increased, and therefore the bending strength and the tensile strength of the insole paper board for the shoe are ensured.

Description

technical field [0001] The invention belongs to the technical field of shoe materials, and in particular relates to an inner sole cardboard for shoes. Background technique [0002] Insole cardboard for shoes, also known as midsole cardboard, refers to the general term for a series of elastic fiber material products containing natural fibers, synthetic fibers and resins, which are processed by special processing technology and used in the shoemaking industry, decoration industry and other products. The inner bottom cardboard has the characteristics of flexibility, elasticity, firmness, air permeability, wear resistance and durability. Insole cardboard for shoes is to replace leather, reduce the cost of the shoemaking industry, and improve product quality. As the basic material of shoes, it meets the comfort and hygiene of the feet, and also meets the requirements of modern hot-melt bonding and other shoemaking technologies. Require. [0003] Cardboard for shoes is one of th...
