Publication number: 20140018757Abstract: A discrete absorbent insert for use in a containment system includes an absorbent core positioned between a first sheet and a second sheet. The first sheet and the second sheet extend beyond the core and are joined together to form a seal. The absorbent core has at least 40% superabsorbent. The absorbent insert has an intake layer of at least 100 gsm between the first sheet and the absorbent core. The first sheet and the second sheet are fluid permeable, spunbond webs of synthetic polymer filaments. The absorbent insert has an absorbent capacity of at least 600 g. The discrete absorbent insert may have an intake rate for a first insult through the first sheet having a first value and an intake rate for a first insult through the second sheet having a second value, wherein a difference between the first value and the second value is less than 20%.Type: ApplicationFiled: July 2, 2013Publication date: January 16, 2014Inventors: Paula Kathleen De Bruin, Alissa Frances Stein, Robert Lee Popp, Marcille Faye Ruman, Connie May McMorrow, Kyle Mark Barriger, Angela Ann Johnston, Katherine Carol Shaw

Publication number: 20140012218Abstract: An absorbable resin, for which a large amount of a plant-derived raw material can be used, and which has an excellent capability of absorbing an aqueous liquid, and has a good gel modulus and therefore can exhibit an excellent absorbing capability under pressurized conditions; and an absorbable composition. An absorbable resin produced by binding an oxidized polysaccharide (A1) having a carboxyl group which may be neutralized with a neutralizing agent and/or a crosslinked product thereof (A2) to a poly(meth)acrylic acid (B1) in which at least one carboxyl group may be neutralized with a neutralizing agent and/or a crosslinked product thereof (B2); or an absorbable composition produced by mixing the component (A1) and/or the component (A2) with the component (B1) and/or the component (B2). The component (A1) has a weight average molecular weight of 2,000-10,000,000. The component (A1) has an acid value of 65-850 mgKOH/g.Type: ApplicationFiled: March 21, 2012Publication date: January 9, 2014Applicant: SANYO CHEMICAL INDUSTRIES, LTD.Inventors: Yusuke Ueda, Yoichi Kanda
