Description

BACKGROUND OF THE PRESENT INVENTIONField of Invention

[0001] The present invention relates to the field of brassiere accessories, and more particularly to a brassiere fastening buckle, its manufacturing method, and a brassiere.Description of Related Arts

[0002] Brassieres are one of the essential garments in modern life. The most common wearing style of existing brassiere is back-fastening, specifically, the back buckle of the back-fastening brassiere comprises a hook portion and a loop portion, wherein the hook portion and the loop portion are respectively sewn onto the two straps of the brassiere. The wearer can secure the brassiere by engaging the hook portion with the loop portion. The hook portion is provided with a row of hooks, and the loop portion is provided with several rows of loops. The hook portion is provided with a row of hooks, and the loop portion is provided with several rows of loops. The wearer can adjust the tightness of the brassiere by engaging the hooks of the hook portion with different rows of loops on the loop portion.

[0003] As the living standards continue to improve, while pursuing the practicality of brassieres, more attention is also being paid to the comfort of wearing brassieres. Consumers generally emphasize the fabric and breathability of the cups when considering the comfort of a brassiere. However, as a close-fitting garment, the comfort of a brassiere is not limited to the part that come into contact with the chest of the wearer, many other details also affect the overall wearing experience of the wearer. Since the back fastening buckle of a brassiere needs to bear the connection force when the brassiere is worn and carry the hooks or loops, the back fastening buckle of a brassiere requires a certain degree of hardness, which can easily cause discomfort to the wearer. Traditionally, the loops of the loop portion are sewn onto the front of the loop portion, which results in corresponding stitches on the back of the loop portion. When worn, the back of the loop portion faces the wearer. Due to the pressure from the stitches, the wearer can easily develop indentations on the back of the wearer, and the friction between the skin and the stitches can cause discomfort during wear, thereby reducing the overall comfort of the brassiere.

[0004] Hence, to hide stitches and improve the skin-friendly effect of the back fastening buckle, two mainstream solutions available in the market are the reverse hemming technique and the hot pressing adhesive technique. Taking the loop portion as an example, the loop portion includes a base fabric and two outer layer fabrics. The outer layer fabrics are made of soft, skin-friendly materials, while the base fabric provides a certain degree of hardness and support, with the loops sewn onto the front of the base fabric. When employing the reverse hemming technique, the two outer layer fabrics are stacked on the front side of the base fabric. and three edges of the base and outer layer fabrics are sewn shut, forming a pocket between the two outer layer fabrics. The pocket is then turned inside out through the unsewn edge, enclosing the base fabric between the two outer layer fabrics. This arrangement hides the corresponding stitches with the outer layer fabrics and alleviates discomfort caused by the base fabric by having the outer layer fabrics in direct contact with the wearer. However, because the outer layer fabrics and the base fabric do not adhere closely to each other, the outer layer fabrics and the base fabric tend to curl after washing, reducing durability. When employing the hot pressing adhesive technique, the two outer layer fabrics are placed on other sides of the base fabric. A hot melt adhesive layer is provided between the outer layer fabrics and the base fabric. The hot melt adhesive layer bonds the outer layer fabrics to the base fabric through a pressing and heat melting process, followed by ultrasonic hot cutting to fix the edges of the fabrics. Although the hot pressing adhesive technique ensures adhesion between the outer layer fabrics and the base fabric, and hides the stitches, the fabric can become scorched and hardened due to the high temperatures during heat cutting, causing discomfort to the wearer due to the stiff edges.SUMMARY OF THE PRESENT INVENTION

The stitches on the base fabric (11) are hidden, ensuring a neat appearance of the brassiere fastening buckles (10) and (10A), while also preventing discomfort for the wearer from contact with the stitches.

[0053] Specially, the surface layer fabric (13) and the perforated fabric (12) are made from a blended material incorporating spandex to improve the lightness and thinness of the brassiere fastening buckles (10) and (10A), and to increase the softness of the brassiere fastening buckles (10) and (10A) when in contact with the skin, providing a cooling sensation in contact with the wearer, thereby improving the comfort of the wearer. Wherein, the base layer fabric (11) has a certain degree of strength, for instance, the base fabric (11) includes a non-woven fabric layer to maintain the structure of the brassiere fastening buckles (10) and (10A).

[0054] Furthermore, referring to FIG. 19, wherein the brassiere (100) comprises a cup portion (30) and two shoulder straps (40) extending from both sides of the cup portion (30), wherein the shoulder straps (40) have two connecting ends (41) suitable for mutual connection. The brassiere fastening buckle (10) is arranged on one of the connection ends (41), and the brassiere fastening buckle (10A) is arranged on the other connection end (41). By engaging the brassiere fastening buckle (10) with the brassiere fastening buckle (10A), the two shoulder straps (40) are connected, thereby enabling the wearing of the brassiere (100).

[0055] Furthermore, wherein the brassiere fastening buckle (10) is connected to the shoulder strap (40) by stitching. Specifically, one of the connection ends (41) is inserted into the opening (101) of the brassiere fastening buckle (10), and the brassiere fastening buckle (10) is stitched and secured to the connection end (41) with sewing threads, wherein the other connection end (41) is inserted into the opening (101) of the brassiere fastening buckle (10A), and the brassiere fastening buckle (10A) is stitched and secured to the connection end (41) with sewing threads.
