Embodiment 1

[0026] Preparation of viscose solution: Cotton pulp with a degree of polymerization of 500 and a mass content of methyl fiber of 93.5% (cotton pulp, also known as refined cotton pulp, is a kind of raw material that is made of cotton linters, refined by alkaline cooking and rinsing) A kind of high-purity cellulose), followed by impregnation, pressing, crushing, aging, yellowing, continuous dissolution, filtration, deaeration and other processes to prepare spinning viscose solution. The mass content of the obtained methyl fiber is 8.9%, the mass content of NaOH is 5.5%, the viscosity (falling ball method: the time required for a 2mm steel ball to fall 20cm from the viscose solution) is 45s, and the maturity (10%NH 4 Cl) 9.4ml, which is the viscose solution to be used.

[0027] Preparation of pre-crosslinked krill protein solution: prepare a 3% sodium hydroxide solution with distilled water in the reactor, add krill protein with a weight of 5% sodium hydroxide solution to the rea...

Abstract

The invention relates to the field of chemical fiber materials and discloses a preparation method for euphausiid protein regenerated cellulose fibers. The preparation method comprises the following steps: preparing a mucilage glue solution for later use; preparing a pre-cross-linked euphausiid protein solution: sequentially adding a sodium hydroxide solution, euphausiid protein and lignin sulfamic acid; agitating at 50-70 DEG C for 4-6 hours; cooling to 35-45 DEG C, keeping the heat and filtering to obtain a filtering solution, namely the euphausiid protein solution; adding a cross-linking agent into the euphausiid protein solution and keeping the heat at 35-45 DEG C to react for 0.4-0.6 hour to prepare the pre-cross-linked euphausiid protein solution; and mixing the mucilage glue solution, the pre-cross-linked euphausiid protein solution and the cross-linking agent and spinning. The fibers prepared by the preparation method have good strength; the strength of the fibers is enhanced; meanwhile, the hand feeling and the luster of the fibers are improved and the fibers can be used as raw materials of a textile industry.

Description

technical field [0001] The invention relates to the field of chemical fiber materials, in particular to a preparation method of krill protein regenerated cellulose fibers. Background technique [0002] As the largest single biological resource in the Southern Ocean, Antarctic krill is an important group of marine zooplankton, supporting the population of huge high-level predators such as penguins, seals, and cetaceans. In addition to being a key organism in a biological system, it has also attracted increasing attention because of its huge biomass and potential fishery resources. [0003] The amino acid scores AAS (except threonine and valine) of essential amino acids in Antarctic krill were all close to or greater than 1; the chemical scores CS (except threonine, valine and tryptophan) were all greater than 0.5, which indicated that It shows that the essential amino acid composition of Antarctic krill muscle is relatively balanced and rich in content. However, the lysine ...
