  • Publication number: 20220040005
    Abstract: Medical gauze includes a warp knitted fabric having a warp and weft direction and composed of loops continued in the warp direction. The warp knitted fabric is made of 100% long fiber containing 70% by weight or more of regenerated cellulose-based long fiber. The warp knitted fabric is preferably configured in a marquisette construction. The regenerated cellulose-based long fiber is preferably cuprammonium rayon. Preferably having a width of equal to or greater than 5 mm and equal to or less than 600 mm, and a weight of equal to or greater than 28 g and equal to or less than 290 g per square meter. As the warp knitted fabric is composed of the loops continued in the warp direction and made of 100% long fiber containing 70% by weight or more of the regenerated cellulose-based long fiber, the occurrence of lint can be reduced to improve lint-free performance.

  • Patent number: 7410479
    Abstract: An absorbent article body part includes a liquid permeable surface side sheet, a liquid impermeable back face side sheet, and an absorbent body, positioned between the sheets, and having flap parts, extending outward to the respective sides of the absorbent body, and is formed by layering an outer layer sheet onto the back face side of the main absorbent article body part. At the outer layer sheet, first and second leg part elastic bodies are positioned with sides at one end being set along leg parts from parts of a dorsal waist part at one side and the other side, intermediate parts crossing a crotch part obliquely, and the sides at the other end being set along the leg parts at parts of a ventral waist part at the other side and the one side. Third leg part elastic bodies are positioned along the longitudinal direction at the flap parts.

  • Patent number: 7291138
    Abstract: A rear elastic area formed by a rear waist region with rear waist elastic members stretchable laterally across the rear waist region. A front elastic area formed by a front waist region with front waist elastic members stretchable laterally across the front waist region. The rear waist region and the front waist region are capable of stretching or contracting in unison. A greater number of rear waist elastic members than front waist elastic members are provided. The rear elastic area is broader than the front elastic area with respect to the longitudinal direction of the diaper body. The body-hugging capability of the diaper body at the rear waist side of the wearer is increased so that the diaper body is prevented from slipping down. This configuration reduces constructive feeling by ensuring that the diaper body is not excessively tight at the front waist side of the wearer.
