Description

Paper diaper and manufacturing process thereof

Technical Field

The invention relates to a paper diaper and a manufacturing process thereof.

Background

Diapers are also common in everyday life, such as adult diapers; the adult diaper is a disposable paper incontinence article, one of adult care products, and is mainly suitable for disposable diapers for incontinent adults. Most products are in the form of a sheet, which is put on the pants and then connected to form a pair of pants by means of an adhesive sheet. Meanwhile, the adhesive sheet has the function of adjusting the size of the waist of the trousers at the same time so as to be suitable for different fat-thin body shapes.

Generally, the structure of the paper diaper is divided into three layers from inside to outside, wherein the inner layer is tightly attached to the skin and made of non-woven fabrics; the middle layer is made of water-absorbing fluff pulp added with a high-molecular water absorbent; the outer layer is a water-proof plastic film.

The prior paper diaper generally has the following characteristics:

1. is easy to put on and take off like real underpants, and is comfortable and comfortable.

2. The funnel-type super-strong instant absorption system is special, the urine wet absorption time can reach 5-6 hours, and the surface layer is still dry and comfortable.

3. The elastic breathable waist belt with 360 degrees is close-fitting and comfortable, and the movement is not bound.

4. The absorption layer contains odor-inhibiting factors, so that embarrassed peculiar smell is inhibited, and the pillow is fresh all the time.

5. Soft elastic leakproof isolation edge, comfort and leakage prevention.

However, the existing paper diaper has a great defect in the manufacturing process, the waist sheet is formed by cutting the outer layer material and the inner layer material of the diaper, and the waist sheet, the outer layer material and the inner layer material are of an integrated structure; meanwhile, the adult paper diaper is generally large in size, a large amount of waste materials are generated by the mode of cutting the waist piece, the waste materials formed after cutting cannot be reused, a large amount of waste of the material of the paper diaper is caused, and meanwhile, the production cost is added, so that the existing paper diaper and the production process need to be improved, a new paper diaper and a method for forming the waist piece of the paper diaper are provided, and the requirement of saving the material is met.

Disclosure of Invention

The invention aims to solve the technical problem of providing a paper diaper and a manufacturing process thereof, wherein the paper diaper is changed in the composition structure through process change, so that the aim of saving materials is fulfilled, and meanwhile, the waist piece is automatically folded, so that the paper diaper is convenient to store and has practicability and wide application.

In order to solve the problems, the invention adopts the following technical scheme:

the utility model provides a paper diaper, includes the paper diaper main part, and the paper diaper main part comprises outer non-woven fabrics, inlayer non-woven fabrics, absorber and waist piece, the waist piece sets up between outer non-woven fabrics and inlayer non-woven fabrics, the waist piece includes two preceding waist pieces and two back waist pieces, and preceding waist piece, back waist piece all are independent individuality, preceding waist piece, back waist do not have the lug connection between the piece.

The method comprises the following steps:

1) placing the absorber on the upper end of the outer layer non-woven fabric in a normal production mode;

2) meanwhile, cutting the waist non-woven fabric through cutting equipment to form a first blocky structure body;

3) uniformly sticking a block-shaped structural body segment to two sides of the upper end of the outer non-woven fabric layer;

4) covering and sticking the inner-layer non-woven fabric on the upper end of the connection part of the first blocky structure body and the outer-layer non-woven fabric;

5) folding the first blocky structure body through a folding mechanism to form a second blocky structure body;

6) the folded block-shaped structural body II is folded again through a folding mechanism and is dotted and fixed to form a block-shaped structural body III;

7) and cutting the paper diaper material with the folded waist piece in a segmented manner to form independent paper diaper individuals.

Preferably, in the step 2), the cutting of the waist panel is a continuous cutting.

Preferably, in step 4), the inner layer nonwoven fabric partially covers both sides of the upper surface of the absorbent body when assembled.

Preferably, in step 5), after the folding of the block structure is completed, a flattening operation is subsequently performed.

Preferably, in the step 7), the cutting of the third block-shaped structure is completed at the same time, so as to form the front waist panel and the back waist panel of two adjacent individual diapers.

The invention has the beneficial effects that: through the change in technology, form the structural change to panty-shape diapers, change the overall structure of original waist piece into sectional type structure for waist piece material reaches the utilization of maximize, has reduced the extravagant problem of a large amount of materials that causes when waist piece shaping cuts in the past, thereby reaches save material's purpose, carries out automatic folding to the waist piece simultaneously, has made things convenient for depositing of panty-shape diapers, has the practicality and the universality of use.
