[0022] The stretchable foamed cotton of the utility model, when producing, first foamed layer 1, woven reinforcement layer 3 and second foamed layer 2 are placed in turn from top to bottom, then adhesive 4 is smeared on antiskid surface 120, after applying pressure, first foamed layer 1 and second foamed layer 2 are attached on the upper and lower surfaces of woven reinforcement layer 3 respectively, after adhesive 4 solidifies, first foamed layer 1, woven reinforcement layer 3 and second foamed layer 2 can be fixed and bonded together.

[0023] The setting of two antiskid surfaces 120 increases the contact area between liquid adhesive 4 and first foamed cotton 1 and second foamed cotton 2, so that adhesive 4 can have a larger bonding area after solidification, and the bonding capacity between first foamed cotton 1 and second foamed cotton 2 is enhanced, so that they are not easy to separate from each other. Antiskid surface 120 is a rough surface.

[0024] Woven reinforcement layer 3 is composed of longitudinal and transverse lines, and hole 31 is formed between the longitudinal and transverse lines. The longitudinal and transverse line weaving structure of woven reinforcement layer 3 restricts the excessive deformation of foamed cotton, ensures that foamed cotton has good tensile strength in all directions of the plane, and avoids foamed cotton from being easily damaged due to stretching.

[0028] The anti-skid layer 6 is made of rubber material. Further, a plurality of protrusions 61 are arranged on the upper surface of the anti-skid layer 6 to improve the anti-skid effect of the anti-skid layer 6.
