Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and examples.

Example (b):

this superfine fiber reinforcing leather, as shown in fig. 1 and 2, including non-woven fabrics layer 1 and fix the cortex 3 in its thickness direction both sides, the equal integrated into one piece in top bottom surface of non-woven fabrics layer 1 has a plurality of reinforcement fine hair 2, and consolidates fine hair 2 fixed connection in cortex 3, and the thickness of cortex 3 is greater than the length of consolidating fine hair 2.

Consolidate setting of fine hair 2, when making lay cortex 3 on non-woven fabrics layer 1, can be with making cortex 3 at the in-process that takes shape, make and consolidate fine hair 2 and insert wherein, increase non-woven fabrics layer 1 and the ascending structural strength of cortex 3 in thickness direction, make both difficult emergence break away from, under the condition so, in case this leather meets with when tearing the latter and drag, cortex 3 can all take non-woven fabrics layer 1 to carry out the atress together, and non-woven fabrics layer 1's tear strength is greater than cortex 3, the structural strength of non-woven fabrics layer 1 is higher simultaneously, can play better effect of resisting to the external force.

Nonwoven layer 1 is formed through nonwoven yarn acupuncture, and consolidate fine hair 2 and form through nonwoven layer 1 sanding, as shown in fig. 3, the nonwoven yarn includes sandwich layer 5, lie in tensile layer 8 and the surrounding layer 12 that lies in the outside in its outside, sandwich layer 5, tensile layer 8 and surrounding layer 12 all are the false twist form setting, surrounding layer 12 includes a plurality of parallel lines in the outsourcing yarn 10 of tensile layer 8 outer lane, outsourcing yarn 10 forms through the false twist of a plurality of superfine nylon yarn 11, it forms to consolidate fine hair 2 through a plurality of superfine nylon yarn 11 formation, sandwich layer 5 forms through 6 twists of polyester fiber and nylon fiber 7, tensile layer 8 forms in 5 outsides of sandwich layer through two 9 mutual spiral interweaves of two nylon fiber.

Sandwich layer 5 in the non-woven yarn has used dacron fiber 6 and nylon fiber 7 for non-woven fabrics layer 1 also can come to drag the effort of dragging that whole leather received through sandwich layer 5 stronger tensile strength has after the acupuncture and resist, it is difficult damaged easily to make this leather, and simultaneously, when two nylon fiber 9 that are located the sandwich layer 5 outside come to protect sandwich layer 5, can also be in the time of atress on the non-woven yarn length direction, can increase nylon fiber two 9 and come further share the effort, improve the tensile strength of non-woven yarn.

The outer covering layer 12 located outside the tensile layer 8 can be when sharing the acting force on the length direction of the non-woven yarns, can also make the outer covering yarns 10 break when fluffing through the sanding machine, then make the superfine nylon yarn 11 of a root scatter, then form and consolidate fine hair 2, because consolidate fine hair 2 essence for the superfine nylon yarn 11 of disconnection, so make its tensile strength intersect better in ordinary superfine chemical fiber, make and consolidate fine hair 2 and play better linkage effect to cortex 3.

One side fixedly connected with rete 4 that non-woven fabrics layer 1 was kept away from to cortex 3, and rete 4 adopts the PTFE plastic film, and the setting up of rete 4 makes cortex 3 can be effectively protected, and it can avoid cortex 3 frequent contact water and air and take place the oxidation ageing problem, further prolongs its life.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that modifications and embellishments within the scope of the present disclosure may be made by those skilled in the art without departing from the principles of the present disclosure.
