DETAILED DESCRIPTION

[0020] See also Figure 1-Figure 2 As shown, the technical solution adopted in this specific embodiment is: a serrated hook groove type mushroom head magic hook, including a hook surface base band 1, a plurality of mushroom head type hooks 2 are vertically fixedly arranged on the upper surface of the hook surface base band 1, the mushroom head type hook 2 includes a column 21 and a head 22, the bottom end of the column 21 is vertically arranged on the upper surface of the hook surface base band 1, the head 22 is arranged at the top of the column 21, the vertical section of the head 22 is mushroom head shaped and the protruding part thereof is away from the column 21, a serrated hook 23 is arranged on the side of the head 22 away from the column 21, the serrated hook 23 is inclined, the serrated hooks 23 of adjacent mushroom head type hooks 2 are inclined in opposite directions, and a side curved hook 24 is arranged on the circumferential edge of the head 22.

[0021] The vertical section of the column 21 is trapezoidal and its short side is located near the head 22. The contact area between the column 21 and the upper surface of the hook surface base belt 1 is large, which can ensure the stability of the connection between the column 21 and the hook surface base belt 1.

[0022] The cross-sectional area of ​​the head 22 is larger than that of the column 21 .

[0023] Among them, a plurality of mushroom head-shaped hooks 2 are evenly distributed on the upper surface of the hook surface base band 1 in a rectangular array.

[0024] The hook surface base band 1 and the mushroom head-shaped hook 2 are integrally formed.

[0025] The hook surface base tape 1 includes a first base surface 14, a second base surface 15, and a third base surface 16 arranged from top to bottom. The mushroom head hook 2, the first base surface 14, and the third base surface 16 are made of the same material, and the first base surface 14 and the third base surface 16 are made of the following components in parts by weight: 70-90 parts of polypropylene; 5-10 parts of polyethylene; 1-5 parts of whitening agent; 1-5 parts of softener; 5-10 parts of thermoplastic elastomer;

[0026] The second base surface 15 is made of the following components by weight: 70-90 parts of polypropylene, 1-5 parts of softener, 10-20 parts of masterbatch, and 5-10 parts of thermoplastic elastomer. After the softener is added to the material and used in combination with the thermoplastic elastomer, it can not only ensure a soft skin feel, but also adhere well to the Velcro surface.
