Abstract

The invention discloses a feather protein fiber and a method for preparing the same. The feather protein fiber comprises the following components: 5-40 parts by weight of feather protein and 60-95 parts by weight of chemical fiber. The method for preparing the feather protein fiber comprises the following steps: A, feather protein spinning solution preparing: dissolving feather in an alkaline aqueous solution comprising sodium silicate and potassium silicate with the total mass concentration of 20-35%, and filtering to obtain the feather protein spinning solution, wherein the mass ratio of the sodium silicate to the potassium silicate is 1:(0.5-1); B, blending the feather protein spinning solution and the chemical fiber spinning solution, and spinning; and C, subjecting the feather protein fiber trickle to coagulation-bath treatment, pickling, washing and drying to obtain the feather protein fiber. The method for preparing the feather protein fiber can effectively ensure that the feather protein and the chemical fiber are fully and uniformly blended to achieve the purpose of spinning.

Description

technical field [0001] The invention relates to a protein fiber and a preparation method thereof, in particular to a wood feather protein fiber blended with chemical fiber and feather protein and a preparation method thereof. Background technique [0002] Feather and down are keratinized products derived from poultry epidermal cells. Among them, down is a green fiber material with excellent characteristics such as light weight, softness, strong moisture absorption, and good warmth retention. In addition to a small amount of soft down components in feathers , and the rest are rigid pinna component structures. The remaining pinnaes etc. after the existing feather has been extracted are often treated as waste, or are used to make feed; although the existing feed made of pinnae has solved the problem of its waste utilization to a certain extent, but Because the pinnae often contain a certain amount of bacteria carried by poultry animals, it is difficult to guarantee the quality...
