Eco-Friendly Handle Leather Capable of Removing Moistures

Abstract

An eco-friendly handle leather contains: a thermoplastic polyurethane (TPU) film and a homogeneous hot-melt adhesion film connected on the TPU film to form a pseudo-adhering sheet, a carrier adhered on the pseudo-adhering sheet and made of hygroscopic weave cloth. The TPU film, the homogeneous hot-melt adhesion film, the carrier and the pseudo-adhering sheet are pressed in a heating and pressurizing manner to polymerize the handle leather. The handle leather is slit into multiple strips, and the multiple strips are cut into the handle leather. Before the pseudo-adhering sheet and the carrier are polymerized, the pseudo-adhering sheet and the carrier are punched to form multiple large-diameter suction holes. The pseudo-adhering sheet is physically polymerized with the carrier via the homogeneous hot-melt adhesion film after being heated and pressurized, and the carrier exposes outside or extends out of the multiple large-diameter suction holes and the multiple small-diameter suction holes.

Claims

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0021] With reference to FIGS. 1-3 and 8, an eco-friendly handle leather capable of removing moistures according to a preferred embodiment of the present invention comprises: a thermoplastic polyurethane (TPU) film 21 and a homogeneous hot-melt adhesion film 22 connected on a bottom of the TPU film 21 to form a pseudo-adhering sheet 2 (as shown in FIGS. 4 and 5), a carrier 3 adhered on a bottom of the pseudo-adhering sheet 2 and made of hygroscopic weave cloth, wherein the TPU film 21, the homogeneous hot-melt adhesion film 22, the carrier 3 and the pseudo-adhering sheet 2 are pressed in a heating and pressurizing manner to polymerize the leather material 4 with a predetermined thickness (as illustrated in FIGS. 1 and 7). The leather material 4 is slit into multiple strips 41 (as shown in FIG. 2) in a predetermined width (, as illustrated in FIG. 1) by using multiple slitting cutters R presented by a dotted line of FIG. 1, and the multiple strips 41 are cut into the eco-friendly handle leather 42 (as shown in FIG. 3).

[0022] Referring to FIG. 6, before the pseudo-adhering sheet 2 and the carrier 3 are polymerized, the pseudo-adhering sheet 2 and the carrier 3 are punched to form multiple large-diameter suction holes 2A, and multiple small-diameter suction holes 2B are formed around the multiple large-diameter suction holes 2A.

[0023] Thereby, the pseudo-adhering sheet 2 is physically polymerized with the carrier 3 via the homogeneous hot-melt adhesion film 22 securely and tightly after being heated and pressurized, and the carrier 3 (i.e., the hygroscopic weave cloth) exposes outside or extends out of the multiple large-diameter suction holes 2A and the multiple small-diameter suction holes 2B, thus producing the eco-friendly handle leather 42 (as shown in FIGS. 1-3).

[0024] As illustrated in FIG. 8, a polymerization portion 3A of the carrier 3 and the pseudo-adhering sheet 2 are located beside the multiple large-diameter suction holes 2A and the multiple small-diameter suction holes 2B, the homogeneous hot-melt adhesion film 22 of the pseudo-adhering sheet 2 is heated and is pressurized so that a part of the homogeneous hot-melt adhesion film 22 enters into gaps of the carrier 3 (i.e., the hygroscopic weave cloth), thus connecting the homogeneous hot-melt adhesion film 22 with the carrier 3. Furthermore, the TPU film 21 is configured to physically polymerize the pseudo-adhering sheet 2 with the carrier 3 without using adhesive and dimethylformamide (DMF), thus obtaining a using safety of the eco-friendly handle leather.

[0025] With reference to FIG. 8, the carrier 3 (i.e., the hygroscopic weave cloth) exposes outside or extends out of the multiple large-diameter suction holes 2A and the multiple small-diameter suction holes 2B (since the carrier 3 and the pseudo-adhering sheet 2 are not pressed and polymerized, a top of the carrier 3 and the pseudo-adhering sheet 2 is waved) and is a water storage zone, and the polymerization portion 3A of the carrier 3 is an auxiliary water storage zone, wherein in the FIG. 8, different cross-sectional lines are used to distinguish zones.

[0026] Referring further to FIG. 8, the handle leather 42 is winded around the handle 5, and waters W expose outside or directly contact with the carrier 3 in a close distance (i.e., the hygroscopic weave cloth) so as to be further absorbed downward, thus drying the handle leather 42. The TPU film 21 is slip resistant, and the flexible carrier 3 is configured to rebound the handle leather 42 after the handle leather 42 is gripped and pressed, thus obtaining a firm grasp, a slip resistance, a high water absorption, and a high flexibility.

[0027] Referring further to FIG. 9, a shape and a size of the handle leather 42 is cut based on using requirements to be applicable for a flat cushion 6, such as a yoga mat or a table mat.

[0028] While the preferred embodiments of the invention have been set forth for purpose of disclosure, modifications of the disclosed embodiments of the invention and other embodiments thereof may occur to those skilled in the art. Accordingly, the appended claims are intended to cover all embodiments which do not depart from the spirit and scope of the invention.
