Abstract

The invention discloses a cashmere protein cellulose fiber, which contains the following components in parts by weight: 5-15% of cashmere protein and 85-95% of cellulose, wherein the cashmere protein is grafted onto cellulose through a silane coupling agent. A preparation method of the cashmere protein cellulose fiber comprises the following steps: (1) preparing 10-20% by mass of cashmere protein alkaline aqueous solution with pH of 11-12, heating the cashmere protein alkaline aqueous solution to 55-65 DEG C, dropwise adding a silane coupling agent, heating the system temperature to 100-110 DEG C after the dropwise addition is over, maintaining the reaction for 2 to 3 hours to obtain cashmere protein pretreatment solution, and then cooling to room temperature for later use; (2) adding the cashmere protein pretreatment solution into viscose according to the proportion of cashmere protein, the mass of which is 10-20% of alphacellulose in viscose, fully mixing and then flowing into a ripening middle barrel which is always kept at the stirring state, maintaining reaction for 6-10 hours to obtain cashmere protein grafted viscose; and (3) directly spinning, washing and drying the obtained cashmere protein grafted viscose to obtain the cashmere protein cellulose fiber.

Description

technical field [0001] The invention relates to the field of functional fiber preparation, in particular to a cashmere protein cellulose fiber and a preparation method thereof. Background technique [0002] Wool is an important raw material for the textile industry. It has the advantages of good elasticity, strong moisture absorption, and good warmth retention. Wool textiles are famous for their luxurious, elegant, and comfortable natural style. Cashmere, in particular, has the reputation of "soft gold", but Due to the high price, it is not used much for the production of non-woven fabrics. The non-woven fabrics produced by good wool are limited to some high-grade industrial fabrics such as needle-punched blankets and high-grade needle-punched felts. It is short wool and coarse wool in wool processing. It is used to produce carpet pads, needle-punched carpet sandwich layers, thermal insulation materials and other products by acupuncture and stitching. This type of wool has d...
