Embodiment 1

[0028] Carry out the following steps:

[0029] (1) Preparation of collagen pretreatment solution: pump 50L of water into the glass-lined reactor, start stirring, and add 10Kg of collagen, then add dilute sodium hydroxide solution to adjust the pH of the system to 9-10 to fully dissolve the collagen Protein and filtered to obtain an alkaline aqueous solution, then heat the collagen aqueous solution to 55-65°C, maintain the system temperature at 55-65°C, add 3.5L epichlorohydrin dropwise to the system within 20-30min under stirring conditions, and dropwise add Then raise the system temperature to 100-110°C, maintain the system temperature at 100-110°C and react for 2 hours to obtain the collagen pretreatment solution, then lower it to room temperature for later use;

[0030] (2) Viscose grafting treatment: Before the viscose enters the aging intermediate barrel, add the collagen pretreatment solution prepared in step (1) with the injection system according to the ratio of collag...

Abstract

The invention discloses a collagen cellulose fiber which is composed of the following components in percentage by weight: 5-15% of collagens and 85-95% of cellulose, wherein the collagens are grafted onto the cellulose through epoxy chloropropane. The preparation process comprises the following steps: (1) preparing collagen alkaline aqueous solution with a mass fraction of 10-20% and a pH value of 9-10, heating the collagen alkaline aqueous solution to the temperature of 55-65 DEG C, dropwise adding epoxy chloropropane, raising the temperature of the system to 100-110 DEG C after dropwise adding, maintaining the reaction for 2-3 hours so as to obtain collagen pretreatment liquid, and reducing to room temperature for later use; (2) adding the collagen pretreatment liquid into viscose according to a ratio of 10-20% of the collagen to alpha cellulose in the viscose, fully mixing, entering a maturing intermediate barrel which is always kept in a stirring state, and maintaining the reaction for 6-10 hours so as to obtain collagen grafted viscose; and (3) directly spinning, washing and drying the obtained collagen grafted viscose, thereby obtaining the collagen cellulose fiber.

Description

technical field [0001] The invention relates to the field of functional fiber preparation, in particular to a collagen cellulose fiber and a preparation method thereof. Background technique [0002] Mask is the most important tool for skin care. Nowadays, with the awareness of maintenance and skin care becoming popular, the mask market is becoming more and more popular. Traditional non-woven masks occupy the vast majority of the market. Most of the masks are as follows: Its added nutrients are used to achieve moisturizing, whitening and anti-aging effects, but there is little research on the mask substrate as a mask carrier. [0003] Collagen is extracted from animal skin and contains a large number of polar groups. It is a moisturizing factor and can prevent tyrosine in the skin from converting into melanin. Therefore, collagen has natural moisturizing, whitening, anti-wrinkle, and freckle-removing effects. Widely used in beauty products. [0004] With the development of ...
