Detailed Description
As shown in fig. 1, a disposable pants-type wearing article substrate according to the present disclosure includes an inner layer 1, an elastic layer 2 and an outer layer 3 laminated and compounded in sequence, wherein the inner layer 1 is a pure cotton spunlaced fabric, the elastic layer 2 is an elastic film, and the outer layer 3 is a cotton soft non-woven fabric.
Specifically, the base material of the disposable pants-type wearing article of this embodiment is designed by considering the material of the inner layer 1, because the inner layer 1 is in direct contact with the skin of the human body when worn, pure cotton material with comfortable touch is required to be used, and simultaneously, the ultrasonic pressure head is required to puncture and squeeze the inner layer 1 when ultrasonic stitching is performed, so that the inner layer 1 is required to have a certain natural curvature and fluffy feel, and simultaneously, a good stretching ratio is required, so that in the production process, when the inner layer 1 is pulled to the stretching ratio of about 2.0 times by the machine tension, cotton fibers are gradually straightened to reduce the layer thickness of the inner layer 1, at this time, ultrasonic stitching can be conveniently performed on the elastic layer 2 and the outer layer 3 after the ultrasonic pressure head punctures and squeezes the inner layer 1, meanwhile, when a consumer actually wears the material, the whole stretching multiplying power of the inner layer 1 is usually kept at about 1.2-1.5, at the moment, the material of the inner layer 1 is required to keep good bending degree and fluffiness, and according to the requirements of the above points, through practical verification, pure cotton spunlaced cloth is selected as the material of the inner layer 1, the material can be in a stacked and bent state before being stretched, after being pulled by machine tension and fully stretched to 2.0 times of stretching multiplying power, the inner layer 1 can be reduced to the thickness capable of being penetrated and extruded by an ultrasonic pressure head, so that the ultrasonic pressure head can penetrate through the inner layer 1 to carry out ultrasonic stitching on the elastic layer 2 and the outer layer 3, and the material can keep good bending degree and fluffiness under the natural wearing state, so that the wearing experience of the consumer is fluffy and comfortable, and the constraint feeling is reduced. In addition, the pure cotton spunlaced fabric has good water absorbability and air permeability, can effectively absorb sweat in the wearing process, and keeps air permeability.
More specifically, the gram weight of the pure cotton spunlaced fabric is designed to be 5-20 g, so that the thickness of the pure cotton spunlaced fabric is moderate, the ultrasonic stitching of the outer layer 3 and the elastic layer 2 can be conveniently carried out through the inner layer 1, and the manufactured disposable trousers type wearing article can be kept light and thin.
The elastic layer 2 needs to have good uniform elasticity and good air permeability, and comprehensively considers the advantages of uniform elasticity and good air permeability of the TPU (Thermoplastic polyurethanes, thermoplastic polyurethane) elastic film as the elastic layer 2, so that the TPU elastic film can effectively avoid wearing marks, has good air permeability, and can further improve the wearing experience of consumers.
Furthermore, in this embodiment, a plurality of ventilation holes penetrating along the thickness direction of the elastic layer 2 are formed, the aperture of each ventilation hole is 1.8 mm-2.2 mm, for example, 2mm, the ventilation holes are arranged in a rectangular array, and the row spacing and the column spacing are 3.8 mm-4.2 mm, for example, 4mm, so that the ventilation holes are uniformly arranged, the ventilation property of the elastic layer 2 can be further improved, and the production and the processing are facilitated.
The cotton soft non-woven fabric is used as the outer layer 3, and has the advantages of light weight, softness, ventilation, certain hardness and low cost, and is suitable for being used as the material of the outer layer 3, more specifically, the gram weight of the cotton soft non-woven fabric is designed to be 10-30 g, so that the thickness of the outer layer 3 is moderate, the wearing article is kept light and thin, and the cotton soft non-woven fabric has good ventilation.
As shown in fig. 2 and 3, the present embodiment further provides a disposable pants-type wearing article 4, which includes a front waist panel 4a, a crotch portion 4b and a rear waist panel 4c connected in sequence, wherein the front waist panel 4a, the crotch portion 4b and the rear waist panel 4c are made of the above-mentioned disposable pants-type wearing article base material, and specifically, the above-mentioned base material can be used to obtain the sheet-shaped wearing article structure in the unfolded state shown in fig. 2 by cutting with an automatic cutting device, and then the waistline edge positions of the front waist panel 4a and the rear waist panel 4c are encircled and sewn to form the pants-type wearing structure shown in fig. 3.
More specifically, the front waist panel 4a and the back waist panel 4c each have an ultrasonic seam area 41 at the waist edge, the ultrasonic seam area 41 is an area where the front waist panel 4a and the back waist panel 4c are connected after being sewn by ultrasonic, the width of the ultrasonic seam area 41 is 3mm to 5mm, the width is the waist width direction in the wearing state, and the seam area range can provide sufficient seam strength, and can be moderate in width and reduce material waste.
The embodiment further provides an ultrasonic pressure head for ultrasonic sewing of waistline, as shown in fig. 4 in detail, the ultrasonic pressure head structure includes an upper pressure head 5a and a lower pressure head 5b which are matched, the upper pressure head 5a has a plurality of trapezoidal protruding blocks which are arranged at intervals, the lower pressure head 5b is provided with a trapezoidal groove which is matched with the position corresponding to the trapezoidal protruding blocks, the trapezoidal protruding blocks can be embedded into the trapezoidal groove, when ultrasonic sewing of waistline is performed, a sewing area is placed between the trapezoidal protruding blocks and the trapezoidal groove, the inner layer 1 is pulled to be in a stretching state by tension of a machine, and at the moment, the upper pressure head 5a structure of the trapezoidal protruding blocks can penetrate through the inner layer 1 and contact with the elastic layer 2 so as to perform effective ultrasonic sewing on the elastic layer 2 and the outer layer 3, thereby forming a pants-type wearing structure.
The base material disclosed by the invention adopts a three-layer composite structure of the inner layer 1 pure cotton spunlaced cloth, the elastic film and the outer layer 3 cotton soft non-woven fabric, so that one surface of the trousers wearing article made of the base material, which is contacted with human skin, is made of the pure cotton spunlaced cloth, the touch feeling is soft and comfortable, the wearing experience of consumers is good, and the trousers wearing article is more friendly to consumers with sensitive skin; and the inner layer 1 is made of pure cotton, so that the material cost is greatly reduced compared with the disposable underpants made of integral pure cotton;
The three-layer composite substrate structure can be cut by using automatic equipment, and the hardness of the elastic film and the cotton soft non-woven fabric is enough to meet the requirement of ultrasonic stitching, so that the waistline of the trousers wearing article can be stitched by adopting the ultrasonic equipment when the waistline is in surrounding stitching, manual stitching is not needed, the trousers wearing article can be produced by using the automatic equipment, the stitching cost can be greatly reduced, the production efficiency is improved, and the requirement of mass production can be met;
The elastic membrane is used as the elastic component, and compared with the elastic membrane with the strip-shaped structures such as spandex filaments and rubber strings, the elastic force applied by the elastic membrane is more uniform, so that wearing marks can be effectively avoided, and the wearing experience of consumers can be further improved.
