Waste feather regenerated pure keratin fiber and preparation method thereof

Abstract

The invention discloses a waste feather regenerated pure keratin fiber and a preparation method thereof. The preparation method of the waste feather regenerated pure keratin fiber comprises the stepsthat performing high-temperature flash explosion treatment on waste feathers and then performing treatment with urea to obtain feather keratin; dissolving the feather keratin, and adding an antibacterial agent while dissolving; adding sodium hexadecyl sulfonate, performing aging, and heating to obtain a spinning solution; and preparing the regenerated keratin fibers by using the spinning solution.The waste feather keratin with excellent molecular weight and yield is obtained by adopting a high-temperature flash explosion and low-concentration urea synergistic treatment method, the antibacterial regenerated keratin fibers with high additional values are developed on the basis, a new solvent system of sodium carbonate, sodium bicarbonate and hexadecyl sodium sulfonate is developed, and thespinnability of a keratin solution is improved.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a pure keratin fiber regenerated from discarded feathers and a preparation method thereof. Background technique [0002] As a natural protein, keratin has very good biocompatibility and cell affinity, has certain mechanical properties, and can be processed. It will have a good development prospect as a textile material. The development and utilization of keratin materials is gradually unfolding, and has gradually moved from primary utilization to the application of degradable and renewable materials. In terms of fibers, pure keratin fibers or composite keratin fibers can be developed; in terms of textiles, home textile fabrics and medical materials can be developed. Discarded feather keratin, as a natural polymer material, is not only rich in sources and low in price, but also has good special properties and has a good development prospect. [0003] As a biomacromo...

However, research in this field has not yet been maturely reported

[0005] In short, the research and application of exploring efficient keratin extraction methods has become a current hotspot. However, due to the complexity of the structure of discarded feathers, the current extraction methods are still unable to obtain keratin with molecular weight and yield that meet the requirements. Based on the keratin The antibacterial pure protein fiber has not been reported yet
