Description
Technical Field
The invention belongs to the technical field of dyeing and finishing, and particularly relates to an all-biological-based cotton fabric and a dyeing and finishing method thereof.
Background
Cotton fibers are one of the important textile materials. The global annual cotton fiber yield is up to 3000 ten thousand tons, accounting for about 81 percent of the global natural fiber yield. Dyeing cotton fabrics is an important process step before cotton textile products enter the market. However, there are still problems in the conventional cotton dyeing and finishing process, such as using dye or finishing agent with potential biotoxicity, environmental pollution and poor market competitiveness. In addition, the proposal of the carbon reaching peak and the carbon neutralization target also provides new requirements for the traditional dyeing and finishing industry with high energy consumption.
In view of increasing importance of consumers on textile health and environmental protection, the textile industry is continuously pursuing green and environment-friendly production technology, and biomass dyeing and finishing reagents extracted from agricultural byproducts are gradually paid attention to. Compared with the traditional synthetic dye, many biological extracts have advantages and application prospects due to soft color light, biodegradability, environmental compatibility and multiple protection functions. Numerous studies have shown that biomass extracts can impart good color and functionality to protein fibers such as silk, wool, and the like. The adsorption mechanism is mainly that groups such as anionic hydroxyl, carboxyl and the like of the natural polyphenol extract are adsorbed on amino groups with positive charges of protein fibers through ionic bond action when the pH value is lower than the isoelectric point of the protein fibers. The research of directly applying the biomass extract to the surface of cotton fabric is less, and the main reason is that the cotton fabric lacks a positively charged dyeing seat, and meanwhile, alcoholic hydroxyl groups on a cellulose structure of a basic constituent unit of cotton fiber are partially ionized, and electrostatic repulsion exists between the alcoholic hydroxyl groups and hydroxyl groups negatively charged by the natural polyphenol extract, so that the direct adsorption is difficult. In addition, how to improve the color fastness of the biomass extract on cotton fabric is also one of key technologies for preventing the industrialized application of the biomass extract on cotton fabric. For this reason, the prior art usually carries out pretreatment on cotton by means of metal ions, carries out surface modification on cotton fibers by utilizing a cationic modifier, and the like. However, some metal mordants such as chromium (Cr), copper (Cu) and some cross-linking agents such as aldehyde cross-linking agents and epoxy cross-linking agents still have certain potential safety hazards, and do not conform to the ideas of ecological textiles and green textile industry. In addition, the metal mordant can be combined with biomass molecules through strong coordination bonds, so that the color light of the metal mordant is withered and dark, and the attractiveness of the textile product is affected.
It is reported that the energy consumption of textile industry in China accounts for 4% of the energy consumption of industry in China, wherein the traditional dyeing and finishing technology by an impregnation method is one of links of high energy consumption in textile processing. The combination of novel energy efficient dyeing and finishing technologies with biomass extracts to achieve textile ecological dyeing and finishing technologies from raw materials to technology is a future development trend of the textile industry.
Disclosure of Invention
Therefore, the invention aims to solve the technical problems of poor affinity and fastness of the polyphenol extract to cotton fibers and high energy consumption of the traditional cotton fabric dyeing and finishing technology in the prior art.
In order to solve the technical problems, the invention provides the all-biological-based cotton fabric and the dyeing and finishing method thereof, and the invention adopts the cationic modifier to cationize the cotton fabric on the premise of not introducing substances for increasing environmental load additionally, so that the adsorption capacity of the cotton fabric on anionic natural polyphenol extracts is improved, the three-dimensional crosslinking among the cationic modifier, the natural polyphenol extracts and the cotton fabric is realized through the baking and crosslinking of the crosslinking agent, so that the washing fastness is improved, and the whole process adopts the ultrasonic auxiliary technology, so that the dyeing and finishing efficiency is improved, and the energy consumption is reduced.
The first object of the present invention is to provide a dyeing and finishing method of an all-bio-based cotton fabric, comprising the steps of,

In one embodiment of the invention, in step (2), the heating is at a temperature of 55-65 ℃; the ultrasonic treatment is 20-40kHz treatment for 25-35min.
In one embodiment of the present invention, in step (2), the pre-baking is a pre-baking at 70-80 ℃ for 12-18min; the baking is at 115-135deg.C for 2-4min.
In one embodiment of the present invention, in the step (2), the ultrasonic treatment is performed by combining a green material with a clean production technology by using an ultrasonic auxiliary technology, and compared with the adsorption rate in the presence or absence of ultrasonic, the time and energy (energy represents cost and carbon dioxide emission) saved can be estimated, so that the energy conservation and emission reduction meet the recent high requirements on industrial production.
A second object of the present invention is to provide an all-bio-based cotton fabric prepared by the method.

Test example 1
(1) Based on example 1, the degree of improvement of the adsorption performance of the natural tea polyphenol extract on the cotton fabric before and after the HACC cationization was evaluated by the adsorption amount on the fabric, and the results are shown in fig. 1.
As can be seen from FIG. 1, the adsorption rate of the lacquer on the surface of the unmodified cotton fabric is lower than 15%, and the adsorption amount is lower than 10mg/L. After HACC cationization modification, the adsorption capacity of the extract of the Chinese lacquer on cotton fabrics is improved by about 4 times, and the adsorption capacity of the extract of the Chinese lacquer is further improved along with the increase of the dosage of the extract of the Chinese lacquer.
The degree of improvement of adsorption efficiency by ultrasonic technology is calculated by nonlinear fitting of pseudo-quadratic kinetic equation (1) to adsorption amounts at different times 1/2 ) (formula 2) for evaluation, the calculation formula is as follows:
wherein t represents adsorption time(s), C t Represents the adsorption amount (mg/g) and k on the fiber per unit mass at time t 2 Representing the pseudo-secondary adsorption kinetic coefficient, C e Represents the saturated adsorption amount (mg/g).
The result shows that the adsorption efficiency can be improved by 20-40% by introducing the ultrasonic technology, the dyeing and finishing processing time is shortened, and the energy consumption is saved.
(2) Based on example 1, the color fastness of the unmodified cotton fabric, the cationically modified cotton fabric, and the anionically co-deposited crosslinked modified cotton fabric in the examples was tested.
Table 1 shows the relevant performance parameters of the final measured cotton fabric:
TABLE 1
(3) Based on example 1, the antibacterial performance and ultraviolet protection performance of cotton fabrics were tested, and the cotton fabrics were divided into 7 groups: 1 is an unmodified cotton fabric; 2 is cation modified cotton fabric; 3 is cotton fabric directly treated by 6g/L of the lacquer palace extract; 4-6 are respectively cation modified cotton fabrics treated by 2g/L, 6g/L, 10g/L of the extract of the Rhizoctonia cerealis and 5wt% of citric acid; 7 is a cotton fabric cationically modified and treated with 10g/L of the Rhus verniciflua extract and 5% by weight of citric acid and subjected to 5 repeated water washes, the results are shown in FIG. 2. As can be seen from FIG. 2, the E.coli inhibition rate of the unmodified cotton fabric was less than 5% (1), and the inhibition rate of the cotton fabric treated with HACC and the Rhizoctonia solani extract respectively was still less than 40% (2-3). The antibacterial property of the cotton fabric treated by 2g/L of the extract of the Rhizoctonia cerealis is higher than 60%, and the antibacterial property is further improved along with the increase of the dosage (4-6). The E.coli inhibition rate after 5 washes was still higher than 80% (7). Also, after the treatment of the extract of the Rhynchosia volubilis, the ultraviolet protection coefficient of the cotton fabric is obviously improved, the UPF of the cotton fabric treated by 10g/L of the extract of the Rhynchosia volubilis is more than 40, and the T (UVA) is higher than the UPF of the cotton fabric treated by the extract of the Rhynchosia volubilis AV Less than 5%, meets the ultraviolet protection requirement, and has an ultraviolet protection coefficient higher than 30 after 5 times of washing.
Test example 2
The cotton fabrics prepared in examples 1 to 5 and comparative examples 1 to 3 were tested for the extract adsorption rate, color fastness, antibacterial rate and ultraviolet protection coefficient.
Table 2 shows the relevant performance parameters of the final measured cotton fabric:
TABLE 2
As can be seen from the results of example 1 and comparative example 1 in table 2, the adsorption rate of tea polyphenol on cotton fabric which is not cationized by chitosan derivative is only 11%, because the hydroxyl group on tea polyphenol is partially ionized into anionic group, and electrostatic repulsive force exists between the anionic hydroxyl group on cellulose structure on cotton fiber, so that the electrostatic repulsive force between the tea polyphenol and the cotton fabric can be remarkably reduced after HACC is added to inhibit adsorption, and adsorption is promoted (as shown in fig. 3). From the results of example 2 and comparative example 2 in table 2, it can be seen that when no bio-based cross-linking agent is added, the dry and wet rubbing color fastness is medium or lower, and after the cross-linking agent is added for baking and cross-linking, the dry and wet rubbing color fastness is about grade 4, which indicates that citric acid is cross-linked with chlorogenic acid and hydroxyl groups on cotton fibers, and the fastness is remarkably improved. Example 4 and example 5 use different chitosan derivatives and natural polyphenols, and the obtained adsorption amount, color fastness and functional results are similar, which shows that the technical scheme has good repeatability and general reference significance. Comparative example 3 and example 3 are adsorption efficiencies, and the results are also shown in test example 1.
The invention combines the ion deposition crosslinking technology of the natural polyphenol extract with the ultrasonic auxiliary technology, solves the problems of low affinity, poor fastness and low efficiency and high energy consumption of the traditional dyeing and finishing technology of the polyphenol extract on cotton fabrics, provides a new thought for improving the antibacterial and ultraviolet protective performance of the cotton fabrics, and has extremely wide application prospect.
It is apparent that the above examples are given by way of illustration only and are not limiting of the embodiments. Other variations and modifications of the present invention will be apparent to those of ordinary skill in the art in light of the foregoing description. It is not necessary here nor is it exhaustive of all embodiments. And obvious variations or modifications thereof are contemplated as falling within the scope of the present invention.
