DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0018] Referring to FIGS. 1-3, a hair accessory in accordance with a first embodiment of the present invention is a hair band (13). The hair band (13) comprises an anti-slip structure consisting of a plurality of elastic silicon rubber pins (3) (or elastic plastic pins) that are evenly distributed over at least one of opposing inner and outer surfaces thereof. When the hair band (13) is fastened to the hair (A), the elastic silicon rubber pins (3) (or elastic plastic pins) are engaged into the hair (A), securing the hair band (13) positively to the hair (A). The hair band (13) is made from a strip of elastic material (1) comprising an elastic base layer (11) and a braided cover layer (12) surrounding the elastic base layer (11).

[0019] The formation of the anti-slip structure on the hair band (13) comprises the steps of:

[0020] preparing a mold (2) that comprises a plurality of cavities (23) defined therein according to the arrangement of the elastic silicon rubber pins (3) of the hair band (13) to be made, a plurality of filling holes (21) located in a top side thereof and a plurality of molten material flow passages (22) in communication between the filling holes (21) and the cavities (23);

[0021] putting the strip of elastic material (1) in a bottom side inside the mold (2);

[0022] feeding molten silicon rubber or elastic plastic material through the filling holes (21) of the mold (2) and the molten material flow passages (22) into the elastic silicon rubber pin cavities (23);

[0023] opening the mold (2) and removing the strip of elastic material (1) with integrated elastic silicon rubber pins (3) (or elastic plastic pins) from the mold (2) after cooled down;

[0024] cutting the strip of elastic material (1) with integrated elastic silicon rubber pins (3) into pieces according to the desired length; and

[0025] bonding two opposite ends (111) of each cut piece to form an individual hair band (13).

[0026] Referring to FIGS. 4-7, a hair accessory in accordance with a second embodiment of the present invention is a shrapnel hairpin (4). The shrapnel hairpin (4) comprises a center pin (42) having a wave-like pin body (421), two clamping arms (41) respectively curved from one end of the center pin (42) in direction toward an opposite end of the center pin (42), and an anti-slip structure consisting of a plurality of elastic silicon rubber pins (3) (or elastic plastic pins) that are evenly distributed over one surface of each clamping arm (41). When the shrapnel hairpin (4) is fastened to the hair (A), the elastic silicon rubber pins (3) (or elastic plastic pins) are engaged into the hair (A), securing the shrapnel hairpin (4) positively to the hair (A). Further, two mating fastening components (411) are respectively located at the free ends of the two clamping arms (41) and detachably fastenable to each other to secure the free ends of the two clamping arms (41) together.

When the hair clip (6) is fastened to the hair (A), the elastic silicon rubber pins (3) (or elastic plastic pins) are engaged into the hair (A), securing the hair clip (6) positively to the hair (A).

[0033] The formation of the anti-slip structure on the hair clip (6) comprises the steps of:
