Description

Technical Field

[0001] The utility model relates to the field of sanitary products, in particular to a fine-denier spandex waist trouser-type diaper. Background Art

[0002] Spandex yarn, also known as polyurethane elastic fiber, is divided into coarse and fine spandex yarns according to its thickness. Generally, spandex yarns less than 20D are called fine denier spandex yarns. The waist of existing pants-type diapers is usually composed of an outer non-woven fabric, an inner non-woven fabric and an elastic band sandwiched between the two. The elastic band is fixed between the two by gluing. The waist of this structure often feels tight to the user because the elastic band used is generally thicker, and the breathability is poor, especially for infants and young children, who generally use it for several hours, and it is easy to feel stuffy when used in summer.

[0003] Chinese patent application No. 202210077678.4 discloses a shorts-type diaper with a bulky waist and a processing method. After the outer packaging structure is folded in half, the ends on the same side of the front and rear ends are bonded to form a shorts shape; the outer packaging structure includes an outer non-woven fabric, an elastic spandex yarn, and an inner non-woven fabric arranged in sequence, and the three are fixed by hot melt adhesive. A buffer layer is provided between the elastic spandex yarn and the inner non-woven fabric or between the elastic spandex yarn and the outer non-woven fabric, and the buffer layer is located at the front and rear ends of the inner non-woven fabric or the elastic spandex yarn. This patent adds some buffering materials to the outer packaging structure, which can reduce the marks on the baby's waist when the shorts-type diaper is worn for a long time, but the outer non-woven fabric, elastic spandex yarn, and inner non-woven fabric are all fixed by hot melt adhesive, which will make the overall air permeability of the waist area poor. Utility Model Content

[0004] Therefore, in view of the above problems, the utility model provides a fine-denier spandex waist pants-type diaper to solve the defects of the prior art pants-type diapers, such as poor air permeability in the waist area and a strong feeling of tightness when used.

[0005] To achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: a fine-denier spandex yarn waist pants-type diaper, comprising a waist component and an absorbent connected to the waist component, the absorbent having a longitudinal direction along the length direction and a transverse direction perpendicular thereto, the waist component comprising a front waist portion and a rear waist portion, the transverse sides of the front waist portion are respectively fixedly connected to the transverse sides of the rear waist portion to form a closed structure with a waist opening, the waist component is composed of an outer layer of non-woven fabric, an inner layer of non-woven fabric and an elastic body arranged therebetween, the elastic body is a fine-denier spandex yarn, the front waist portion has a front waist first area, a front waist second area and a front waist third area arranged in sequence along the longitudinal direction, The elastomer in the first area of ​​the front waist is fixed between the outer non-woven fabric and the inner non-woven fabric by hot-melt adhesive, the elastomer in the second area of ​​the front waist is fixed between the outer non-woven fabric and the inner non-woven fabric by ultrasonic wave, one end of the absorbent is fixed in the third area of ​​the front waist, the back waist part has a first area of ​​the back waist and a second area of ​​the back waist arranged in sequence along the longitudinal direction, the elastomer in the first area of ​​the back waist is fixed between the outer non-woven fabric and the inner non-woven fabric by hot-melt adhesive, the elastomer in the second area of ​​the back waist is ultrasonically welded between the outer non-woven fabric and the inner non-woven fabric, the other end of the absorbent is fixed in the second area of ​​the back waist, and an elastic PU film layer is also provided in the first area of ​​the back waist.

[0006] Furthermore, the number of the fine denier spandex yarns is 20-500, and the spacing between the fine denier spandex yarns is 4.2-6 mm.

[0007] Furthermore: the elastic PU film layer is arranged on the inner side of the inner non-woven fabric.

[0008] Furthermore: the outer surface of the fine denier spandex yarn is wrapped with cool fiber yarn.

[0009] Furthermore: the cooling fiber yarn is wound around the outer surface of the fine denier spandex yarn in a spiral winding manner.

[0010] Further: the cool feeling fiber yarn is coolmax fiber yarn.

[0011] Furthermore: the fineness of the coolmax fiber is 8-30D.

[0012] Furthermore: the elastic body in the first area of ​​the front waist is fixed between the outer non-woven fabric and the inner non-woven fabric by point-shaped hot melt adhesive bonding.

[0013] Furthermore: the longitudinal dimension ratio of the first front waist area, the second front waist area and the third front waist area is 1:2:2.

[0014] By adopting the above technical scheme, the beneficial effects of the utility model are as follows: the waist circumference component of the pants-type diaper of the utility model is composed of an outer non-woven fabric, an inner non-woven fabric and an elastic body arranged between the two, and the elastic body is selected from fine denier spandex yarn, so that the user will not feel squeezed. By dividing the front waist and the back waist into zones, the first zone of the front waist is close to the uppermost end of the user's waist, and the elastic body in this zone is fixed by hot melt adhesive, so that the elastic body can be stably fixed in the waist area, and the elastic body in the second zone of the front waist is fixed by ultrasonic welding, and no glue is used in this area, which improves the overall air permeability of the waist area, and at the same time, the softness of this area is also improved. The elastic body in the second zone of the back waist is also ultrasonically welded between the outer non-woven fabric and the inner non-woven fabric, which improves the air permeability and softness of this area and improves the comfort of use. In addition, an elastic PU film layer is also arranged in the first zone of the back waist, and the elastic PU film layer is both soft and elastic, so that the skin that fits this area is more comfortable. Furthermore, by winding the cooling fiber yarn on the outer surface of the fine denier spandex yarn, the waist part has better air permeability. BRIEF DESCRIPTION OF THE DRAWINGS
