The biggest issue facing our planet is climate change, caused mainly by CO2 emissions generated by combustion of fossil fuels by industry, automobiles and heating of buildings. To mitigate climate change, we should make extensive efforts to find economically sustainable solutions for the use of wood. At present the large scale uses of wood are: building materials, paper and textile. This proposal deals with a new way of making functional cellulose fibers, which can be made into filaments, smart textiles, high value cellulose biomaterials, such as superhydrophobic fibers and fibers of high tenacity, as well as high value dyed fibers. The long term vision is to have a sustainable cellulose bioproducts industry in Canada, thus increasing considerably the use of wood. Presently many pulp and paper mills in Canada are idle and could be readily converted to mills producing functional cellulose fibers, provided we can do so in a sustainable and economically viable way. We will provide the knowledge to produce functional cellulose fibers by covalently linking interesting molecules to carboxylated cellulose fibers during the production process, such as hydrophobic molecules, dyes, crosslinkers to increase strength and reduce swelling. Superhydrophobic and superoleophilic fibers (e.g. for cleaning up oil spills) will also be produced. Canada with its large supply of wood should become a world leader in producing bioproducts from wood. The expected outcomes are the production of smart cellulose fibers, hydrophobic and superhydrophobic filaments, smart textiles, and textiles that do not require further dyeing, all made from kraft fibers, produced by Canadian kraft mills. The novel fibers will be easy to modify, thus extending their range of potential applications. The strengthening of the Canadian forest industry will benefit Canada, create jobs and contribute greatly to the gradual conversion of a fossil fuel based economy to a true bio-economy.

我们星球面临的最大问题是气候变化，主要是由工业，汽车和建筑物加热的化石燃料燃烧产生的二氧化碳排放。为了减轻气候变化，我们应该做出广泛的努力，以寻找使用木材的经济可持续解决方案。目前，木材的大规模用途是：建筑材料，纸张和纺织品。该提案涉及一种制造功能性纤维素纤维的新方法，可以将其制成细丝，智能纺织品，高价值纤维素生物材料，例如超疏水纤维和高度固定性的纤维以及高价值染色纤维。长期的视野是在加拿大拥有可持续的纤维素生物产品行业，从而大大增加了木材的使用。目前，加拿大的许多纸浆和造纸厂都是闲置的，只要我们可以以可持续且经济上可行的方式做到这一点。我们将通过在生产过程中将有趣的分子与羧化的纤维素纤维联系起来，例如疏水分子，染料，交叉链接器，以增加强度并减少肿胀，从而提供知识来产生功能性纤维素纤维。还将产生超疏水和超嗜碱性纤维（例如用于清洁漏油）。 加拿大拥有大量木材的供应应成为从木材生产生物产品的世界领导者。预期的结果是生产智能纤维素纤维，疏水性和超疏水细丝，智能纺织品和不需要进一步染色的纺织品，它们都是由加拿大牛皮纸生产的牛皮纤维制成的。新颖的纤维将很容易修饰，从而扩展其潜在应用范围。加拿大森林产业的加强将使加拿大受益，创造就业机会，并为基于化石燃料的经济逐步转换为真正的生物经济。
