A method for preparing a modified cellulose aerogel for glycoprotein separation is provided. In this method, cellulose aerogel is employed as a substrate. The cellulose aerogel is known to have a three-dimensional network structure with extremely high porosity and specific surface area and extremely low density. So, by using the cellulose aerogel as a substrate, it is possible to provide the glycoproteins to be separated with more binding sites. PEI dendrimer has abundant functional groups and can easily be modified. By modifying the cellulose aerogel substrate with the PEI dendrimer, it is possible to improve the density of the phenylboronic acid bound to the substrate, thereby leading to higher affinity toward the glycoproteins to be separated.

A carbon fiber reinforced composite material includes carbon fiber and a thermosetting resin composition. The thermosetting resin composition is a cured product of a liquid composition that contains unsaturated polyester, a curing agent, a polymerization initiator, and a nanocarbon/nanocellulose complex containing nanocarbon modified by functional a group and nanocellulose. The nanocarbon/nanocellulose complex is dispersed in the thermosetting resin composition. The thermosetting resin composition contains 0.05 to 15% by weight of the nanocarbon/nanocellulose complex. A maximum point stress of the carbon fiber reinforced composite material in a tensile test according to JIS K 7164 is 410 N/mm.sup.2 or more. A maximum point stress of the carbon fiber reinforced composite material in a three-point bending test according to JIS K 7171 is 310 N/mm.sup.2 or more.

A method for recycling textiles comprising cellulose with the following steps of: optionally disintegrating the textile, Swelling the cellulose, under reducing conditions, wherein at least one reducing agent is present at least during a part of the swelling, and then performing at least one of the following two bleaching steps in any order: i) bleaching the material with oxygen at alkaline conditions with a pH in the range 9-13.5, and ii) bleaching the material with ozone at acid conditions below pH 6. An advantage is that the yield is improved at the same time as excellent decolourization is achieved. If the recycled material is used in viscose manufacture, the risk of clogging nozzles and so on is reduced.
