A preferred technical feature: it also includes a pull-up pants identification piece, the identification piece is located between the non-woven fabric and the elastic block.

A preferred technical feature: the composite absorbent sheet is provided with a first side retaining wall and a second side retaining wall from the outside to the inside; the first retaining wall is higher than the second retaining wall.

A method of making leak-proof pull-up pants: Step 1: The inner side of the outermost non-woven fabric is affixed with a labeling piece, and the labeling piece is an inverted elastic type, that is, the front of the labeling piece is pasted on the inner side of the non-woven fabric. Side; 2. The elastic block is processed, the elastic block is two pieces; the middle area of one elastic block is cut off by a chopper to prevent the elastic block from shrinking together and cannot be unfolded normally; 3. The elasticity after processing in step 2 The front and back ends of the non-woven fabrics are attached to each other, and the elastic sheet cut with a chopping knife is located at the front end, and the marking sheet is located in the cut area of the elastic part; 4. The setting of the composite absorbent sheet: the composite absorbent sheet is placed on the elastic waistline 5. Press and fix, fold the two ends of the elastic waist inward and fix it to wrap the composite absorbent sheet inside, and then connect the two ends of the elastic waist to form a waist part; finally cut to shape.

A preferred technical feature: Steps 1 and 2 are performed simultaneously, and are pressed together by equipment.

Beneficial technical effects:

In the present invention, the elastic waistline is arranged into the outer non-woven fabric and the elastic blocks at both ends of the non-woven fabric, so that when the human body wears, there is only a thin layer of non-woven fabric at the bottom of the composite absorbent sheet. The pull-up pants save cost; compared with the three-piece type, with the function of non-woven fabrics, they can fit on the user's legs, and their leak-proof effect is good; their comfort is also better. The two-piece type is known to include the bottom layer, that is, the waistline and the diaper; the waistline includes non-woven fabrics, and the elastic blocks are overlapped and arranged. Is it true that the elastic blocks are only located at both ends as in the patented technology, so as to reduce costs. , is also comfortable to wear.

The middle area of the elastic block in the elastic waistline is provided with a cutting part, and the rear area is provided with a marking block. The technical solution is to make the marking block more beautiful. The existing pull-up pants are designed to prevent the elastic block from shrinking. The logo blocks are condensed together, and the non-woven fabric and the inner layer, that is, the elastic band in the elastic block, are directly cut off at one time, and the logo block will also have a broken part; it is slightly broken, which is not beautiful.

Detailed ways

The present invention will be further described below through specific embodiments.

A leak-proof pull-up pants, comprising a composite absorbent sheet 1, an elastic waist portion 2 for fixing the composite absorbent sheet 1 on the human body, the elastic waist portion includes an outermost non-woven fabric 21 and a non-woven fabric 21 adhered to the non-woven fabric. The upper elastic block 22, the elastic block 22 is located at both ends of the non-woven fabric 21, and the two ends of the elastic waist portion are provided with an inward folding structure, and the composite absorbent sheet 1 is supported on the non-woven fabric 21 and Both ends are located within the folded structure of the elastic block 22 .

A preferred embodiment: the elastic block 22 includes a rubber band and a non-woven fabric, an elastic band is arranged on the upper surface of the non-woven fabric, and the elastic band is bonded by spraying glue.

A preferred embodiment: the elastic waist part 2 includes a front end 23 and a rear waist part 24 ; the middle region of the elastic block of the front waist part is provided with a cutting part 231 .

The preferred embodiment also includes a pull-up pants identification piece 25, the identification piece 25 is located between the non-woven fabric 21 and the elastic block 22, and the identification piece 25 is attached to the non-woven fabric 21 and fixed to the elastic block.

A preferred embodiment: the two sides of the composite absorbent sheet 1 are respectively provided with a first side retaining wall and a second side retaining wall from the outside to the inside; the first retaining wall is higher than the second retaining wall .

The present invention also relates to a method for making leak-proof pull-up pants: Step 1: An inner side of one end of the outermost non-woven fabric 21 is affixed with a marking piece 25, and the marking piece 25 is an inverted elastic type, that is, a marking The front of the sheet is attached to the inner side of the non-woven fabric 21; 2. The elastic block 22 is processed, and the elastic block 22 is two pieces; the middle area of one elastic block 22 is cut off by a chopping knife to form a chopping area, so as to prevent the When the logo block is pasted, the elastic block drives the logo sheet to shrink together, and it cannot be unfolded normally, which affects its appearance; 3.
