FIG. 1A , a well-knownfastener 10 includes ahook surface 11 with a plurality of hooks 111 and atextured surface 12 with a plurality ofloops 121. When thehook surface 11 and thetextured surface 12 are coupled together, the hooks 111 will hook theloops 121 to connect together. When the hooks 111 would like to separate from theloops 121, a force is applied to separate the hooks 111 and theloops 121 and thefastener 10 can be used repeatedly. - The
hook surface 11 and thetextured surface 12 of thefastener 10 shown inFIG. 1A are disposed on a belt body fixed in a specific object, such as acushion 14 or aleather surface 13 to be correspondingly applied on thecushion 14, by a sewing method to form anobject 1. However, thefastener 10 assembled by the sewing method will form a gap adjacent tosewing positions 112 and 122. After using a period of time to tear and adhere repeatedly, the gap neighboring thesewing positions 112 and 122 will become larger and the belt body with thehook surface 11 or thetextured surface 12 will be loosed from the object. Therefore, the structure of thefastener 10 will be damaged and the lifetime of the product with thefastener 10 will he shortened. - Therefore, please refer to

By the tenacity of the interlocking fibers on the textile material 21, thefastener 2 made by this method is not easy to form a breach and the applying tearing forces Pb and Pc are not easy to expand a potentially formed breach after thefastener 2 being repeatedly used. However, once an edge of the plastic thin film 22 forms a breach 23, because the molecules of the plastic thin film 22 are arranged in the same direction, the crack of the breach 23 will propagates along the arrange direction of the molecules of the plastic thin film 22 as thefastener 2 is seriously torn apart. Therefore, the plastic thin film 22 and the fiber 211 of the textile material are also easy to be torn to damage the structure of thefastener 2. Moreover, large usage of adhesive agents will cause a cost problem. - Thus, how to manufacture a fastener having a structure without being easily damaged and being capable of resisting tear propagation and at same time to reduce manufacturing cost for the fastener are problems for those skilled in the art to solve.
