Description
Technical Field
The application belongs to the technical field of textile fabric dyeing, and particularly relates to alginate fibers and a dyeing method thereof.
Background
The alginate fiber is a novel green biodegradable fiber prepared by taking sodium alginate extracted from natural seaweed as a raw material and adopting a wet spinning process. The excellent moisture absorption performance, film forming and fiber forming performance, good biodegradability and biocompatibility are emphasized.
The alginate fiber is widely applied in the field of medical dressing at present, and has great potential in the aspects of high-grade clothes, underwear fabrics and decorative textiles.
The smooth handfeel of the alginate fibers brings wearing comfort and spinning difficulty. On the one hand, it is currently difficult to realize pure spinning yarns of alginate fibers in the related art. On the other hand, because the price of the alginate fiber is slightly higher at present, alginate fiber blended fabrics are more appeared on the market.
The alginate fiber and cotton blended yarn and the wool blended yarn are two large varieties, and the blended yarn has excellent wearability such as bacteriostasis, flame retardance and the like, so that the alginate fiber and cotton blended yarn has good industrial application prospect in the fields of clothing and industrial textiles.
However, alginate fibers are poorly acid and alkali resistant and when exposed to solutions of ammonium salts, Na +, K + and H + ions, the fibers swell and even dissolve. This renders dyeing of alginate fibres extremely difficult in current dyeing systems. The problem of difficult dyeing of alginate fiber is a bottleneck limiting the large-scale application of alginate fiber in the textile field.
The prior art reports partial research on the dyeing of the alginate fiber, but still has some defects.
For example, Chinese patent CN103981744A, a salt-free dyeing method of calcium alginate fiber. The method comprises the steps of pretreating calcium alginate fibers to be dyed by using an aluminum sulfate aqueous solution, then carrying out salt-free dyeing by using a direct dye, and finally fixing color by using a calcium chloride aqueous solution. This patent has made great progress in increasing the depth of dyeing, but calcium chloride fixation can calcify the fiber, losing the flexibility of the fiber.
Chinese patent CN106049101A, a method for fast dip-dyeing seaweed non-woven fabric at normal temperature and enhancing ultraviolet resistance. The method is characterized in that hexadecyl trimethyl ammonium chloride is combined with copper phthalocyanine pigment to rapidly dye seaweed non-woven fabrics, wherein the hexadecyl trimethyl ammonium chloride is used as a dyeing accelerant and a surfactant, and the addition of the hexadecyl trimethyl ammonium chloride can have certain influence on the strength of seaweed fibers.
There are also some current processes for salt-free dyeing of cotton that cannot be used for dyeing alginate fibers due to various limitations. For example, CN108914630A, the concentration of caustic soda in the pretreatment solution is 2-6g/L, and the process can make the alginate fiber basically dissolved. For example, CN106498770A, the used cation modifier is an adsorption type cation modifier in the modification process of cotton, and caustic soda is not used. However, the obvious linear quaternary ammonium salt macromolecules have poor adsorption and crosslinking effects with the alginate fibers, and the alginate fibers are also swelled and dissolved, so that the use performance of the alginate fibers is influenced.
In view of the above, there is a need for a dyeing method that can solve the problem of difficult dyeing of alginate fiber, and does not damage the morphological structure of alginate fiber and reduce the strength of alginate fiber.

Detailed Description
The following description of the embodiments is merely exemplary in nature and is in no way intended to limit the present disclosure. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The embodiment of the application provides a dyeing method of alginate fibers, which comprises the following steps:
s10, preprocessing the alginate fibers by adopting a five-membered ring quaternary ammonium salt polymer;
s20, dyeing the alginate fibers obtained in the step S10 by using a dye;
s30, adopting a five-membered ring quaternary ammonium salt polymer to carry out color fixing treatment on the alginate fiber obtained in the S20.
In the above embodiments, the alginate fiber of the embodiments of the present application can be used to prepare alginate fiber blended fabric, and the alginate fiber blended fabric is a blended fabric of alginate fiber and other one or more fibers. For example, the alginate fiber blended fabric may be at least one of: alginate fiber/cotton blended fabric, alginate fiber/viscose blended fabric, alginate fiber/wool blended fabric, alginate fiber/cashmere blended fabric and alginate fiber/silk blended fabric.
In the above embodiments, the alginate fibers of the embodiments of the present application are easy to dye and have bright colors. The dyeing agent can be selected from one or more of direct dye, acid dye, reactive dye, natural dye and indigo dye for dyeing.
In the above embodiment, the purpose of pretreating the alginate fiber with the five-membered ring quaternary ammonium salt polymer is to improve the dye uptake of the alginate fiber during dyeing, reduce the loss rate of the alginate fiber, and improve the soaping fastness of the alginate fiber. The dyeing rate of the alginate fiber blended fabric obtained by the preparation method provided by the embodiment of the application is greater than or equal to 85%, and the soaping fastness is greater than or equal to level 4.
The principle of the embodiment of the present application that can achieve the above object is as follows. Sodium alginate is a block linear polysaccharide formed by connecting two kinds of uronic acid with different structures through C-1, 4 bonds, namely beta-D-mannuronic acid (M unit for short) and alpha-L-guluronic acid (G unit for short). The two structural units in the sodium alginate molecule are distributed in a molecular chain in the form of polymannuronic acid (M) n and polyguluronic acid (G) n, and the two structural units are connected by alternative MG or polyalternative (MG) n, and the chemical structure is as follows:
when the sodium alginate dope encounters a coagulation bath containing calcium chloride, it rapidly transforms into a water-insoluble calcium alginate gel. This process is mainly based on the fact that the GG segment and Ca2+ produce an egg-shell structure, thereby producing alginate fibers. Many monovalent salts destabilize alginate fibers, i.e., disrupt their "egg-shell" cross-linked structure.
One of the keys of the present application is: the seaweed fiber is pretreated by adopting a five-membered ring quaternary ammonium salt polymer. The five-membered ring quaternary ammonium salt polymer has a structure similar to that of the M unit of alginate fiber, has better planarity, and can be easily adsorbed and crosslinked with the M unit to replace Ca2+The probability of (2) is low. As the five-membered ring quaternary ammonium salt polymer has higher cation density, the five-membered ring quaternary ammonium salt polymer can provide cation promotion to be combined with anionic dye, and simultaneously can adsorb different alginate fiber macromolecular chains to finally assist an egg-shell system, thereby forming a stable dyeable alginate systemAnd simultaneously, the stability and the mechanical property of the alginate fiber can be ensured as much as possible. After dyeing is finished, for some varieties with particularly high requirements on color fastness, the five-membered ring quaternary ammonium salt polymer structure can also be used as a cationic color fixing agent to crosslink dyes and alginate fibers, so that the color fastness is further improved.
In conclusion, the alginate fiber of the embodiment of the application has good dyeability, and can be dyed by commercial direct dye without salt. The dyeable alginate fiber produced by the embodiment of the application has bright dyeing color and good fastness. The fiber can keep the original shape in the dyeing process, no obvious dissolution phenomenon occurs, and the mechanical property is not obviously reduced.
