Abstract
The invention discloses a collagen/cellulose composite fiber and a preparation method thereof. The composite fiber is mainly formed by 5-45wt% of collagen and 45-85wt% of cellulose. The preparation method comprises the following steps: (1) adding collagen solution to cellulose viscose solution and mixing the solution uniformly; (2) after defoaming the mixed solution, carrying out spinning formation in coagulating bath to obtain an as-spun fiber; and (3) carrying out aftertreatment on the as-spun fiber to obtain the collagen/cellulose composite fiber. The composite fiber and the preparation method have the following beneficial effects: the excellent properties of the collagen are well retained by carrying out blended spinning on the collagen solution and the cellulose viscose solution; the prepared composite fiber has excellent low immunogenicity and biocompatibility and good health effects such as skin care, cosmetology and the like besides good cellulose fiber wearability; and the composite fiber is suitable to prepare high-grade undervest, costume and such high-grade skin care and cosmetology products as face tissues, face masks and the like.
Description
Technical field
The present invention relates to the composite fibre cellulose fiber, be specifically related to a kind of cellulose composite fiber by cellulose and collagen blending spinning preparation, and a kind of preparation method of collagen/cellulose composite fiber.
Background technology
Collagen is a kind of biological polymer substance, plays the part of the role of conjunctive tissue in zooblast, is one of critical raw material of tool of biotech industry, also is that the very huge the best of demand is given birth to doctor's material.Collagen mainly is present in skin, bone, tooth, tendon, ligament and the blood vessel of animal, is the important composition material and the functional mass of connective tissue.Collagen is a kind of extracellular protein, and it is the triple helices structure that is twisted into by 3 α peptide chains, and 3 polypeptide chains make its molecular structure highly stable, and have reduced immunogenicity and excellent biological compatibility again with the mutual interlock of hydrogen bond.The active forces such as hydrophobic bond that the bar-shaped helical structure of collagen uniqueness and collagen peptide interchain exist ionic bond, hydrogen bond, Van der Waals force and non-polar group to produce make it compare with vegetable protein and have higher toughness and intensity.Collagen is as biomaterial for medical purpose, and most important character is its reduced immunogenicity.Next is a biocompatibility, is meant good interaction between collagen and host cell and the tissue.Collagen can be by specific proteasome degradation, i.e. biological degradability.Collagen shows that to the function of human body skin is had protective effect and can keep suitable elasticity, makes the hard tool elasticity of bone, makes the eyes can printing opacity, and it is transparent that cornea keeps, and impels muscle cell to connect and tool elasticity and gloss.
In recent years, the application of collagen in textile material obtained R and D, but all be the modification that collagen is used for synthetic fiber, it is the copolymer that forms by collagen and high polymer copolymerization or graft modification, the structure of collagen molecules changes after the copolymerization, its performance also is affected, and the collagen composite fibre of preparation has lost the original premium properties of collagen.And collagen and cellulose all are linear macromolecules, there is certain similitude on the structure, be easy to combination, the compatibility of two kinds of solution is good, the good wearability that has based on viscose itself, both combinations will be embodiments of viscose functionalization and imitation biochemistry, and having preferably, research and development are worth.
Summary of the invention
First technical problem to be solved by this invention is: the deficiency at prior art exists provides a kind of collagen/cellulose composite fiber with reduced immunogenicity, biocompatibility, skin-protection and health-care effect.
Second technical problem to be solved by this invention is: the deficiency at prior art exists provides a kind of preparation method with collagen/cellulose composite fiber of reduced immunogenicity, biocompatibility, skin-protection and health-care effect.
For solving above-mentioned first technical problem, technical scheme of the present invention is:
A kind of collagen/cellulose composite fiber, described composite fibre mainly are made up of the cellulose of the collagen of 5～45wt% and 45～85wt%.
For solving above-mentioned second technical problem, technical scheme of the present invention is:
A kind of preparation method of collagen/cellulose composite fiber may further comprise the steps:
(1) collagen solution is joined in the cellulose viscose solution, the addition of described collagen (calculating by solid state collagen albumen) is 10～50wt% of first fibre in the viscose solution, mix with viscose solution, being prepared into falling ball viscosity is the plain mixed solution of collagen fabric of 40～60s;
(2) with after the described mixed solution deaeration processing, spinning moulding in the coagulating bath that contains sulfuric acid, zinc sulfate, sodium sulphate obtains as-spun fibre;
(3) as-spun fibre is comprised washing, desulfurization, oil, dry post-processing step, obtain collagen/cellulose composite fiber.
The cellulose viscose solution is that to adopt cellulose pulp be raw material, adopts conventional steps preparations such as comprising dipping, squeezing, pulverizing, experienced, yellow, dissolving and maturation.
Preferably, the content of collagen is 10～50wt% in the described collagen solution.
Each components contents is in the described coagulating bath: sulfuric acid 100～150g/l, zinc sulfate 6～13 g/l, sodium sulphate 330～450 g/l, the temperature of described coagulating bath is 30～55 ℃.
Preferably, the desulfurizing agent that adopts during described desulfurization is a sodium sulfite.
The concentration of described desulfurizing agent sodium sulfite is 5～10g/l, and described desulfurization temperature is 75～85 ℃.
Owing to adopted technique scheme, the invention has the beneficial effects as follows:
1, the present invention utilize similar on collagen and the cellulosic molecule structure, be easy to combine, the good characteristics of compatibility of two kinds of solution, add collagen solution in cellulose viscose solution spinning after the blend by suitable addition, collagen/the cellulose composite fiber that makes, the premium properties that has well kept collagen, except that having the good wearability such as sucting wet air permeability of cellulose fibre, also have good health care effects such as good reduced immunogenicity, biocompatibility, cosmetology.The fabric that adopts this composite fibre to be prepared into, feel is full, and gloss is better, is particularly suitable for high-grade cosmetology articles for use such as high-grade underskirt, dress and personal adornment and face-cloth, facial mask.
2, the present invention adopts sodium sulfite as desulfurizing agent when the desulfurization of preparation collagen/cellulose composite fiber, has effectively avoided adopting the loss of alkali as the desulfurizing agent collagen, has improved the retention of collagen in composite fibre.
