Abstract
Official abstract text for this publication.
A composite body includes starch composite particles containing starch, a plasticizer, and a crosslinking agent, and fibers, the starch composite particles being dispersed between the fibers.
First claim
Opening claim text (preview).
What is claimed is: 1 . A composite body comprising: starch composite particles containing starch, a plasticizer, and a crosslinking agent; and fibers, wherein the starch composite particles are dispersed between the fibers. 2 . A composite body comprising: starch composite particles containing starch and a plasticizer; a crosslinking agent; and fibers, wherein the starch composite particles are dispersed between the fibers. 3 . The composite body according to claim 1 , wherein the total content [% by mass] of the starch, the plasticizer, and the crosslinking agent in the composite body is 1.5% by mass or more and 80% by mass or less. 4 . The composite body according to claim 1 , wherein the plasticizer is one or more selected from sugar alcohols. 5 . The composite body according to claim 4 , wherein the sugar alcohols are one or more selected from sorbitol, erythritol, and D-mannitol. 6 . The composite body according to claim 1 , wherein when the total content of the plasticizer and the starch is 100% by mass, the content [% by mass] of the plasticizer is 10% by mass or more and 80% by mass or less. 7 . the composite body according to claim 1 , wherein the crosslinking agent is one or more selected from carboxylic acids. 8 . The composite body according to claim 7 , wherein the dicarboxylic acids are one or more selected from succinic acid, adipic acid, and sebacic acid. 9 . The composite body according to claim 1 , wherein the content [% by mass] of the crosslinking agent in the starch composite particles is 1% by mass or more and 50% by mass or less. 10 . The composite body according to claim 2 , when the total content of the starch composite particles and the crosslinking agent is 100% by mass, the content [% by mass] of the crosslinking agent is 1% by mass or more and 50% by mass or less. 11 . The composite body according to claim 1 , wherein the average particle diameter [μm] of the starch composite particles is 1 μm or more and 50 μm or less. 12 . The composite body according to claim 1 , wherein the fibers contain cellulose. 13 . The composite body according to claim 1 , wherein the composite body is a buffer.
