Description

Technical Field

[0001] This utility model relates to a pair of underwear with high comfort. Background Technology

[0002] Underwear of existing technology, such as Figure 1-2 The underwear includes a pair of briefs 1, which has a longitudinal direction and a transverse direction perpendicular to the longitudinal direction. Longitudinally, with the crotch area as the center, an abdominal area and a back area are formed at the front and back, respectively. The briefs include an outer covering layer 2 and an inner lining pad 3, with the inner lining pad adhesively attached to the inside of the outer covering layer. Heat-pressed seams 5 are provided at the two side edges of the abdominal area and the two side edges of the back area.

[0003] In the automated continuous production process of the aforementioned underwear, it is necessary to cut the continuous fabric on a continuous conveyor belt to obtain a shape like... Figure 2 The fabric, which is close to an I-shape or dumbbell shape, is then formed by the hot pressing line 5.

[0004] In the aforementioned prior art, for automated continuous production, the abdominal and back areas are flat, meaning the fabric in the abdominal area cannot directly form the desired bulge for men. During use, the fabric's elasticity is used to conform to the front of the crotch, resulting in a strong feeling of tightness and pressure, leading to poor comfort. For individuals with larger hips, the back area of ​​the underwear also suffers from the same problem. How to further improve the comfort of underwear and reduce its tightness is a technical problem that needs to be solved in this field. Utility Model Content

[0005] The present invention aims to provide a pair of underwear with high comfort.

[0006] To achieve the above objectives, the technical solution of this utility model is specifically implemented as follows:

[0007] This utility model provides a pair of highly comfortable underwear. The underwear is made of a one-piece cut fabric with symmetrical sides along its horizontal center line and through-holes distributed on both sides of the horizontal center line. The front and back edges of the fabric have first and second herringbone notches, respectively. The underwear includes front and back joining portions located in the abdominal and back areas, respectively. The front joining portion is formed by joining a pair of edges of the first herringbone notch on the front edge of the fabric through sewing, ultrasonic welding, or heat fusion. The back joining portion is formed by joining a pair of edges of the second herringbone notch on the back edge of the fabric through sewing, ultrasonic welding, or heat fusion. During production, the fabric is folded inward along the horizontal center line to overlap the edges of the first and second herringbone notches, forming the front and back overlapping portions, respectively. Then, the two layers of fabric in the front and back overlapping portions are joined together by sewing, ultrasonic welding, or heat fusion to form the underwear.

[0008] If the underwear is men's underwear, the curvature of the first herringbone notch is greater than that of the second herringbone notch, in order to accommodate the requirement that the front of the crotch of men's underwear needs to protrude, thus avoiding the situation of constricting the user's crotch and the front of the crotch, thereby improving the comfort of using the product.

[0009] If the underwear is women's underwear, the curvature of the first herringbone notch is smaller than the curvature of the second herringbone notch, in order to adapt to the actual requirements of the front crotch area of ​​women's underwear, so that the fabric fits the skin and thus improves the comfort of the product.

[0010] The underwear is made of synthetic fiber fabric and has a crotch area. A cotton lining pad is provided on the inner side of the crotch area. A reinforcing strip of synthetic fiber fabric is covered on the four sides or a pair of symmetrical edges of the lining pad. The reinforcing strip, the edge of the lining pad, and the crotch area of ​​the underwear are joined together by heat fusion or ultrasonic welding.

[0011] During the heat fusion or ultrasonic welding process, the reinforcing strip and the chemical fiber at the opposite position of the crotch melt, and the chemical fiber solution penetrates bidirectionally into the fabric layer on the edge of the inner lining and fuses together. After cooling and solidification, the reinforcing strip, the edge of the inner lining, and the underwear are bonded together.

[0012] The inner lining includes at least one layer of cotton fabric, and the underwear and reinforcing strips are made of elastic fabric.

[0013] The reinforcing strip is formed by a single cut and is in a closed loop, or the reinforcing strip comprises a pair of strips symmetrically arranged on both sides of the inner lining.

[0014] The beneficial effects of this utility model are as follows: (1) Compared with the prior art of cutting the fabric into dumbbell shape, then folding the fabric in half and joining the two ends, the abdominal area and back area of ​​the underwear of this utility model are formed by overlapping the edges of the first and second herringbone notches of the fabric. The arc edges of the herringbone notches on the front and back sides are the abdominal area and back area of ​​the underwear after forming. After the abdominal area and back area are stretched, they naturally form a spherical surface. When in use, the fabric does not need to be elastically deformed to fit the crotch, without tightness or pressure, avoiding marks, and providing high comfort. It meets the requirements of the front crotch of men's underwear and the back crotch of women's underwear. For users with larger buttocks, underwear with a larger arc edge of the second herringbone notch can be used according to the corresponding model, thereby enriching the product models and meeting more segmented needs. The fabric of the underwear is cut and formed in one go, without the need for a second cut, which is conducive to high-speed production on a fast production line and improves production efficiency. (2) In the underwear of this utility model, the edge of the inner lining is joined to the crotch of the underwear by a reinforcing strip. During use or washing, the inner lining is not easy to detach and is durable. In this utility model, only the edge of the inner lining is joined to the crotch of the underwear by a reinforcing strip, so that the non-peripheral part of the inner lining is separated from the synthetic fiber fabric of the crotch and is glue-free, which is conducive to breathability, thus conducive to the dryness of the inner lining, thus conducive to hygiene, and improves the comfort of the user's underwear. (3) In this utility model, if only a pair of symmetrical edges of the inner lining are covered with reinforcing strips, the other pair of symmetrical edges of the inner lining are not joined to the reinforcing strips and the crotch of the underwear, which is further conducive to breathability and also makes it convenient for the user to insert a sheet or medicine with super absorbent polymer material between the inner lining and the crotch fabric of the underwear, thus enriching the product function.

[0023] like Figure 3 The underwear is made of fabric 10 cut in one piece. The two sides of the horizontal center line L of the fabric 10 are symmetrical, and through holes 11 are distributed on both sides of the horizontal center line L. The front and back edges of the fabric are respectively formed by a first herringbone notch 12 and a second herringbone notch 13. The underwear includes front and back joints located in the abdominal area and back area of ​​the underwear, respectively. The front joint 14 is formed by sewing, ultrasonic welding or heat fusion of a pair of edges of the front edge of the fabric with the first herringbone notch. The back joint 15 is formed by sewing, ultrasonic welding or heat fusion of a pair of edges of the back edge of the fabric with the second herringbone notch.

[0024] During production, the fabric 10 is folded inward along the transverse center line L to overlap the pair of arc-shaped edges of the first herringbone notch 12 and the pair of arc-shaped edges of the second herringbone notch 13, forming a front overlap and a back overlap, respectively. Then, the two layers of fabric in the front and back overlaps are joined together by sewing, ultrasonic welding, or heat fusion to form a front joining portion 14 and a back joining portion 15, thus forming underwear. Figure 4 As shown.

[0025] If the underwear is men's underwear, the curvature of the arc edge of the first herringbone notch 12 is greater than the curvature of the arc edge of the second herringbone notch 13, so as to meet the requirement that the front of the crotch of men's underwear needs to protrude, avoid the situation of tightening the user's crotch, and thus improve the comfort of the product.

[0026] If the underwear is women's underwear, the curvature of the arc edge of the first herringbone notch 12 is smaller than the curvature of the arc edge of the second herringbone notch 13, so as to adapt to the actual requirements of the front crotch of women's underwear, so that the fabric fits the skin and thus improves the comfort of the product.
