It relates to a pad for urinary incontinence panties having a function of preventing leakage of water in a fold portion that efficiently prevents water leakage according to the present invention.

In accordance with the recent rapid aging trend, the demand for urinary incontinence panties is rapidly increasing. These urinary incontinence panties do not use a high absorbent such as silica gel, which is difficult to dry after being absorbed, so that they can be reused, and absorbent and waterproof with reusable fabric is the main part of the urinary incontinence panties of small capacity. Conventional urinary incontinence panties It is usually composed of a structure in which urine is absorbed by overlapping an upper double weave fabric (water absorption layer) for diffusion of urinary urine, a middle double weave fabric (absorbent layer) for urine absorption, and a lower double weave fabric (waterproof layer) for waterproofing.

However, the conventional method of overlapping an absorbent fabric and a waterproof fabric is useful in preventing urine from flowing down from the top to the bottom because there is no strong absorbent such as silica gel inside, but it is difficult to prevent urine from spreading in the left and right directions. . In addition, when the manufactured urinary incontinence pad is attached to the panties through sewing, a problem occurs in that urine flows down through a hole formed in the seam band portion during the sewing process. An adhesive can be used instead of sewing, but it is difficult to solve the problem of separation of the pants and the pad during the washing process.

In order to solve this problem, Korean Patent Publication No. 10-2021-0091678 entitled "Reusable incontinence pants with improved waterproofness and manufacturing method thereof" has been proposed.

Through this, it is possible to prevent the lateral diffusion of urine in the incontinence pad, and the efficiency of the pad can be increased through the balance and harmony of the lower diffusion and the lateral diffusion. By being combined, a new bonding structure that can prevent leakage of urine by reducing the stitching required for bonding has been proposed.

However, since the prior art has a structure in which the lower cover and the waterproof layer are sewn to the upper cover through double bending in order to prevent the lateral diffusion of urine in the incontinence pad, the step difference in the outer portion is large, resulting in inconvenience due to contact with the skin when worn. and the manufacturing process is complicated. In addition, the anti-diffusion dam having the guide groove must be separately formed, and the anti-diffusion dam part that is quilted also forms another protruding step in the pad part in contact with the skin, so that when worn, Inconvenience is further caused, and the overall manufacturing process is more complicated, resulting in increased manufacturing cost and lowered manufacturing efficiency.
