preparation example Construction

[0027] Please refer to Figure 1 to Figure 3 Shown, a kind of preparation method of side waist can open and close paper diaper of the present invention, comprises the following steps:

[0028] Step 1: Stretch the TPU film along its width direction; compound the first non-woven fabric and the second non-woven fabric on both sides of the stretched TPU film, and obtain waist elastic fabric after cutting;

[0029] Step 2. After the magic hook is cut, it is bonded with the waist elastic cloth obtained in step 1 to obtain a semi-finished product of the side waist;

[0030] Step 3. Cutting the semi-finished side waist product obtained in step 2 into individual side waists; performing secondary compounding of the side waist and the upper part of the diaper to obtain a secondary compounded semi-finished product;

[0031] Step 4. After the core body is cut, the secondary composite semi-finished product obtained in step 3 and the bottom layer of the diaper are integrally composited and ...

Embodiment 1

[0050] A method for preparing a paper diaper with an openable side waist, specifically comprising the following steps;

[0051] Step 1: Stretch the TPU film with a thickness of 0.025mm and a width of 200mm along its width direction; compound the first non-woven fabric and the second non-woven fabric on both sides of the stretched TPU film, and cut it to obtain a waist elastic fabric ;

[0052] Step 2. After the magic hook is cut, it is bonded with the waist elastic cloth obtained in step 1 to obtain a semi-finished product of the side waist;

[0053] Step 3, the semi-finished product of the side waist obtained in step 2 is arc-cut and sectioned to form a continuous side waist, and then the continuous side waist is divided into individual sides;

[0054] Step 4. Ultrasonically press the upper non-woven fabric 11 and the lower non-woven fabric 12 into 3D lines to obtain the surface layer non-woven fabric 9, and the leak-proof enclosure 10 obtained by compounding the protective ...

Embodiment 2

[0060] The preparation device for preparing waist elastic cloth according to Embodiment 1 of the present invention comprises a frame and a first mechanism, a second mechanism, a third mechanism and a fourth mechanism arranged on the frame:

[0061] The discharge ends of the first mechanism, the second mechanism and the third mechanism are respectively connected to the feed end of the fourth mechanism;

[0062] The first mechanism includes a first uncoiling air shaft 15, a first tension swing rod 16, a first deviation corrector 17, and a first pair of pressure rollers 18 arranged in an assembly line;

[0063] The second mechanism includes a second uncoiling air shaft 20 arranged in an assembly line, a second tension swing rod 21, a second pair of pressure rollers 22, and a second deviation corrector 23;

[0064] The third mechanism includes a third uncoiling air shaft 24, a third tension swing bar 25, a third counter-pressure roller 26, a third deviation corrector 27, and a fou...

Abstract

The invention belongs to the technical field of paper diapers, and particularly relates to a paper diaper with side waists capable of being opened and closed and a preparation method of the paper diaper. The first non-woven fabric and the second non-woven fabric are compounded on the two sides of the stretched TPU film, and the waistline elastic cloth is obtained after slitting; slitting magic hooks, and bonding the magic hooks with the obtained waistline elastic cloth to obtain a side waist semi-finished product; the obtained side waist semi-finished product is cut into single side waists; performing secondary compounding on the side waists and the upper layer part of the paper diaper to obtain a secondary compounded semi-finished product; and integrally compounding and cutting the core body, the obtained secondary compounded semi-finished product and the bottom layer part of the paper diaper after the core body is slit to form a final finished product. According to the paper diaper, the waistline can be adjusted, and the problem that a traditional pants-type paper diaper is inconvenient to wear is solved; according to the production process, the splayed wheel expansion mechanism is matched with the ultrasonic compound machine for use, so that the production efficiency is higher, and the production process is suitable for industrial large-scale production.

Description

technical field [0001] The invention belongs to the technical field of diapers, in particular to a diaper with an openable side waist and a preparation method thereof. Background technique [0002] Traditional absorbent sanitary products are generally dominated by waist-type diapers and pants-type diapers. The closure system of the waist sticker type diaper is realized by the matching of the front and rear elastic waist and the left and right magic hooks. Waist sticker type diapers do not need to take off the pants and shoes when wearing them, just pass through the crotch of the human body, and stick the left and right magic hooks to the front waist sticker to realize wearing. It is convenient to wear, but the close-fitting effect is insufficient. Pants-type diapers are a closed system composed of a closed 360° elastic waist composed of spandex yarn and non-woven fabrics. Thanks to the underpants-style design, its close-fitting effect is significantly better than that of w...
