Alginate derived from seaweed is a natural polysaccharide able to form stable gel through carbohydrate functional groups largely used in the food and pharmaceutical industry. This article deals with the use of sodium alginate as an adhesive binder for wood fibres/textile waste fibres biocomposites. Several aldehyde-based crosslinking agents (glyoxal, glutaraldehyde) were compared for various wood/textile waste ratios (100/0, 50/50, 60/40, 70/30 and 0/100 in weight). The fully biomass derived composites whose properties are herewith described satisfy most of the appropriate requirements for building materials. They are insulating with a thermal conductivity in the range 0.078-0.089 W/m/K for an average density in the range 308-333 kg/m3 according to the biocomposite considered. They are semi-rigid with a maximal mechanical strength of 0.84 MPa under bending and 0.44 MPa under compression for 60/40 w/w wood/textile waste biocomposites with a glutaraldehyde crosslinking agent.
藻酸盐来源于海藻，是一种天然多糖，通过碳水化合物官能团形成稳定的凝胶，大量用于食品和制药行业。本文介绍了海藻酸钠作为木质纤维/纺织废料纤维生物复合材料的粘合剂。本文比较了几种醛基交联剂（乙二醛、戊二醛）在不同木材/纺织废料比例（100/0、50/50、60/40、70/30 和 0/100，按重量计）下的应用。本文描述了完全由生物质衍生的复合材料，其性能满足大多数建筑材料的要求。它们具有隔热性能，导热系数在 0.078-0.089 W/m/K 之间，平均密度在 308-333 kg/m3 之间，具体取决于所考虑的生物复合材料。根据所用的戊二醛交联剂，对于 60/40 w/w 木质纤维/纺织废料生物复合材料，其弯曲强度最大可达 0.84 MPa，压缩强度最大可达 0.44 MPa，具有半刚性。
