Elastic coated fabric and method for manufacturing the same

Abstract

An elastic coated fabric and method for manufacturing the same are disclosed. The inventive method includes the steps of pouring into a opening-top mold an amount of liquid substance which would be elastic after coagulation, depositing a fabric substrate on the liquid substance, and coagulating the liquid substance to form an elastic coating on the fabric substrate's surface. The elastic coated fabric includes an elastic fabric substrate, and an elastic coating having a raised pattern consisting of at least one narrow strip attached to the elastic fabric substrate. The narrow strip is dimensioned and arranged so that it may be stretched in the same way as the elastic fabric substrate, thus enabling the elastic coating to be attached to the elastic fabric substrate closely and permanently.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1 to 3, there is shown a preferred embodiment of an inventive method for manufacturing an elastic coated fabric. The method includes the steps of:

a) preparing a opening-top mold 1 and pouring into the opening-top mold 1 an amount of liquid substance 2 which would be elastic after coagulation;

b) depositing a fabric substrate 3 on the liquid substance 2; and

c) coagulating the liquid substance 2 to form an elastic coating 4 on the fabric substrate 3.

In the step a), the liquid substance may be polyurethane (PU) in a single-fluid or double-fluid state.

Referring still to FIGS. 2 and 3, the opening-top mold 1 preferably has its inner bottom bearing a recessed pattern 11 consisting of narrow grooves, so that the liquid substance 2 may form the elastic coating 4 having a raised pattern on the fabric substrate 3.

More preferably, pigment may be applied to the recessed pattern 11 of the mold 1 before the liquid substance 2 is poured, so that the liquid substance 2 in the recessed pattern 11 is mixed with the pigment and forms an elastic coating 4 having a colored, raised pattern on the fabric substrate 3. Alternatively, the liquid substance 2 may be mixed with the pigment before being injected or poured into the mold 1.

In step b), the fabric substrate may be an elastic cloth. In certain application, it may also be a usual or common fabric.

Referring to FIG. 4, an elastic coated fabric 6 manufactured according to the above-mentioned method includes a elastic fabric substrate 61 partially covered with an elastic coating 62.

In this illustrated embodiment, the elastic fabric substrate 61 is shaped into an endless band, which is to be used as a protective band worn around the wrist, elbow or knee of human body, especially for sport. The elastic fabric substrate 61 may also be shaped into a long strip or any other suitable shape for other purposes.

The elastic coating 62 is made of elastic substance, such as elastic plastic, rubber, or preferably polyurethane (PU) resin, and has a raised pattern 63 consisting of a plurality of crossed narrow strips, as clearly shown in FIG. 4. These narrow strips may be connected with each other or, alternatively, may be separate from each other.

As the elastic fabric substrate 61 is being stretched due to the motion of the human body, the narrow strips in such shape and arrangement enable themselves to be stretched in the same way as the fabric substrate 61, thereby ensuring the elastic coating 62 to be attached to the elastic fabric substrate 61 closely and permanently.

From the foregoing, it is apparent that the present invention is advantageous in that:

1. the elastic coating of the present invention can be closely attached to the elastic fabric substrate without the risk of separating therefrom; and

2. the elastic coating may have a raised pattern consisting of narrow strips in different sizes and colors, thereby providing the fabric substrate with an attractive appearance.

Although embodiments together with structures and functions of the present invention have been described in detail, many modifications and variations may be made from the teachings disclosed hereinabove. Therefore, it should be understood by those skilled in the art that any modification and variation equivalent to the spirit of the present invention be regarded to fall into the scope defined by the appended claims.

Claims
