Description

Technical Field

[0001] The utility model relates to the technical field of disposable absorbent pants, in particular to a flat elastic fabric. Background Art

[0002] Elastic cloth is used in the waistbands of current disposable absorbent pants such as pull-up pants for infants and young children, diapers, menstrual pants and pull-up pants for adults. The elastic force of the elastic cloth allows the pants to wrap and fit the skin. The existing elastic cloth has a three-layer structure, including an inner layer, an elastic layer and an outer layer. The elastic layer is composed of a plurality of elastic bands arranged therein, and the elastic layer is glued between the inner layer and the outer layer. Traditional elastic cloths all use elastic bands with circular cross-sections, and the average spacing between the elastic bands is greater than 4mm. Therefore, large-diameter elastic bands with an average decimeter greater than 400 are used to prevent the absorbent pants from falling off due to the amount of liquid absorbed or activity during wearing. The elastic binding force of the circular elastic bands is linearly strangling the skin surface, which can easily strangle the skin surface to redness and itching.

[0003] This case arises to solve the above problems. Utility Model Content

[0004] Therefore, in view of the above problems, the utility model proposes a flat elastic fabric for solving the problem of the waistband of disposable absorbent pants squeezing the skin.

[0005] In order to solve the above technical problems, the solution adopted by the utility model is: a flat elastic cloth with elastic bands, comprising an inner layer, an elastic layer, and an outer layer arranged in sequence from the inside to the outside, the elastic layer comprising a plurality of flat elastic bands with rectangular cross-sections, the elastic bands being arranged between the inner layer and the outer layer, the outer side surface of the elastic bands being spaced at a fixed distance from the inner surface of the outer layer to form a plurality of external fixed segments distributed at a fixed distance, the inner side surface of the elastic bands being spaced at a fixed distance from the outer surface of the inner layer to form a plurality of internal fixed segments distributed at a fixed distance, the outer layer being located between adjacent external fixed segments being wrinkled to form an external breathable portion spaced at the same distance as the elastic bands, and the inner layer being located between adjacent internal fixed segments being wrinkled to form an internal breathable portion spaced at the same distance as the elastic bands.

[0006] A further improvement is that the outer fixing section and the inner fixing section overlap or stagger.

[0007] A further improvement is that the width of the elastic band is 0.5-3 mm, the thickness is 0.1-0.5 mm, and the spacing between the elastic bands is 3-12 mm.

[0008] A further improvement is that the width of the elastic band is 0.5 mm, the thickness is 0.1 mm, and the spacing between the elastic bands is 3 mm.

[0009] Further improvement: the width of the rubber band is 2 mm, the thickness is 0.3 mm, and the spacing between the rubber bands is 6 mm.

[0010] Further improvement: the width of the rubber band is 3 mm, the thickness is 0.5 mm, and the spacing between the rubber bands is 12 mm.

[0011] By adopting the foregoing technical solution, the beneficial effects of the present utility model are as follows:

[0012] In this case, the elastic cloth improves the traditional circular rubber band with a circular cross-section into a flat rubber band with a rectangular cross-section. The flat rubber band fits the skin with its surface, increasing the stress area of compression, reducing the constriction feeling during the wearing of the disposable absorbent pants, and avoiding the redness and itching caused by long-term wearing of the disposable absorbent pants.

[0013] The flat rubber is connected to the inner layer and the outer layer by means of spaced gluing and fixing. The inner layer and the outer layer are wrinkled under the drive of the contraction of the flat rubber band. At the same time, the inner layer and the outer layer not connected to the rubber band are spaced apart from the rubber band, and are puffed up and protruded under the drive of the contraction of the rubber band to form an inner ventilation part and an outer ventilation part, improving the air permeability of the elastic cloth to improve the air permeability of the waistband of the disposable absorbent pants.

[0014] A further beneficial effect is that the outer fixing section coincides with or is staggered from the inner fixing section. When they coincide, the inner and outer sides of the rubber band are simultaneously coated with glue, which is beneficial to simplifying the equipment and improving the manufacturing efficiency. When they are staggered, the outer fixing section is located inside the inner ventilation part, and the inner fixing section is located inside the outer ventilation part, and the overall air permeability of the elastic cloth is better.

[0015] A further beneficial effect is that by using flat rubber bands with different widths and thicknesses, different elastic force magnitudes can be given to the elastic cloth, so as to be further applicable to disposable absorbent pants for infants and disposable absorbent pants for adults.
