Durable absorbent pant
A durable absorbent pant is disclosed. The pant includes a crotch portion with a crotch gusset including an absorbent assembly. The crotch gusset may be configured to exhibit a maximum Longitudinal Elongation of 25 percent to 100 percent and a Longitudinal Tensile Modulus of 10 gf/mm to 100 gf/mm. The described stretch characteristics provide a pant with improved body conformity for improved containment of fluids (such as urine) discharged by the wearer.
1. A durable absorbent pant, comprising:
a front waist portion with a front waist edge and left and right front leg opening edges;
a rear waist portion with a rear waist edge and left and right rear leg opening edges;
a crotch portion comprising a crotch gusset, the crotch portion having a forward portion meeting the front waist portion and a rearward portion meeting the rear waist portion; and
left and right hip side portions joining the front waist portion to the rear waist portion and thereby forming a waist opening with a waist opening edge comprising the front waist edge and the rear waist edge, and left and right leg openings;
wherein, when the pant is in an opened configuration in which the front waist portion and rear waist portion are separated at the hip side portions, the pant has a longitudinal axis and a lateral axis, with an intersection thereof, the intersection occurring in the crotch portion;
wherein each of the front waist portion, rear waist portion and crotch gusset comprises a knitted material;
wherein the crotch gusset comprises an absorbent assembly comprising a wearer-facing layer comprising a knitted fabric material, an absorbent layer comprising knitted terrycloth material, and a liquid impermeable barrier layer disposed to the outward-facing side of the absorbent layer, and wherein the crotch gusset exhibits a maximum Longitudinal Elongation of 25 percent to 100 percent and a Longitudinal Tensile Modulus of 10 gf/mm to 100 gf/mm and a Volume Absorption Capacity of at least 0.50 ml/cm 3 , up to 1.2 ml/cm 3 ;
wherein the crotch portion has a central Caliper at the intersection of the lateral and longitudinal axes; and
wherein the crotch gusset is joined to the front waist portion at a first seam and the rear waist portion at a second seam, wherein the first and second seams comprising one or more of stitching, adhesive bonding or thermal bonding.
2. The pant of claim 1 , wherein the pant is a brief pant and has a minimum crotch width CW of at least 8 cm.
3. The pant of claim 1 , wherein the absorbent assembly comprises a plurality of layer components, and at least one of the layer components comprises an elastic material.
4. The pant of claim 3 , wherein the elastic material comprises one or more of elastic fiber, elastic thread, elastic yarn or elastic film.
5. The pant of claim 3 , wherein the elastic material comprises a material selected from the group consisting of PET, TPEE, elastane and polyurethane, and combinations thereof.
6. The pant of claim 1 , wherein the knitted fabric material is knitted of one or more yarns that comprise synthetic material selected from the group consisting of polyester, polyamide, polypropylene, polyethylene and combinations thereof.
7. The pant of claim 1 , wherein the absorbent knitted fabric material is knitted of one or more yarns that comprise material selected from the group consisting of cotton, rayon, viscose, polyester, polyamide and combinations thereof.
8. The pant of claim 1 , wherein the absorbent knitted fabric material comprises a microfiber yarn.
9. The pant of claim 1 , wherein the Caliper is no greater than 5 mm.
10. The pant of claim 1 , wherein the crotch portion comprises four layers comprising a wearer-facing layer, an absorbent layer directly beneath the wearer-facing layer, a liquid impermeable barrier layer beneath the absorbent layer and an outward-facing layer beneath the barrier layer.
11. The pant of claim 10 , wherein any of the wearer-facing layer, absorbent layer and outward-facing layer comprises elastic filaments.
12. The pant of claim 10 , wherein the barrier layer is a polymeric film.
13. The pant of claim 12 , wherein the polymeric film has been applied in liquid, semi-molten or molten form to an outward-facing side of a superadjacent knitted fabric and has thereby partially penetrated texture of the outward-facing side thereof.
14. The pant of claim 12 , wherein the polymeric film is an elastomeric film.
15. The pant of claim 12 , wherein the polymeric film comprises a material selected from the group consisting of PET, TPEE, elastane and polyurethane, and combinations thereof.
16. The pant of claim 1 , wherein the wearer-facing layer is thermal compression bonded to the absorbent layer in a pattern of thermal compression bonds.
17. The pant of claim 1 , wherein the crotch gusset comprises inside leg opening edges, and wherein the wearer-facing layer, the absorbent layer, and the liquid impermeable barrier layer are joined at the inside leg opening edges.
