Performance test
The dyed fabrics of examples 1-8, comparative examples 1-3 were sampled and tested for the following fabric properties:
(1) crease recovery Performance test
Selecting GB/T3819 and 1997 determination recovery angle method for crease recovery of textile fabrics as a standard, testing each sample for 3 times, taking an average value after measurement, and filling the measurement result in table 1;
(2) test of bacteriostatic Property
Selecting a part 1 of GB/T20944.1 evaluation of antibacterial performance of textiles: agar plate diffusion method as standard, each sample is tested for 3 times, and after measurement, the average value is taken, and the measurement result is filled in table 1;
TABLE 1
As can be seen from table 1, the dry quick stretch wrinkle recovery angle and the dry slow stretch wrinkle recovery angle in examples 1 to 3 are both 160 ° or more, and the radial and latitudinal strengths are both 230N or more, so that the fabric prepared by the method has good wrinkle resistance; in the embodiments 1 to 3, the bacteriostatic rate of escherichia coli is more than 99.0%, and the bacteriostatic rate of staphylococcus aureus is more than 99.0%, so that the cloth prepared by the method has good antibacterial performance.
As can be seen from table 1, example 3 differs from example 4 in that: the mass ratio of chitosan, sodium periodate and tartaric acid in example 3 is 95:1:2.6, the mass ratio of chitosan, sodium periodate and tartaric acid in example 4 is 110:1:2.6, the dry-fast-elastic crease recovery angle and the dry-slow-elastic crease recovery angle in example 4 are both reduced, and the radial strength and the latitudinal strength are also reduced, which is probably because the chitosan is difficult to be completely oxidized by the sodium periodate after the ratio of the chitosan is increased, the amount of aldehyde groups in the product is small, the etherification addition effect with hydroxyl groups on the fabric is weak, the anti-wrinkle effect of the whole fabric is difficult to be improved, and the test result of crease recovery performance is reduced.
As can be seen from table 1, example 3 differs from example 5 in that: the mass ratio of chitosan, sodium periodate and tartaric acid in example 3 is 95:1:2.6, the mass ratio of chitosan, sodium periodate and tartaric acid in example 5 is 95:1:3, the dry-quick-stretch wrinkle recovery angle and the dry-slow-stretch wrinkle recovery angle in example 5 are both increased, and the radial and latitudinal strengths are decreased, which is probably because the carboxylic acid and the hydroxyl groups on the cellulose may be esterified and crosslinked at high temperature after the ratio of tartaric acid is increased, a network structure is formed in the amorphous region of the fiber, the carboxylic acid and the chitosan which are solidified and attached to the surface of the fiber through esterification and crosslinking also undergo amidation reaction, so the wrinkle recovery angle is increased, but a thicker finishing layer is formed on the surface of the fiber, so that the elasticity of the fabric is decreased, and the radial and latitudinal strengths of the sample in example 5 are decreased.
Example 3 compared with example 5, the bacteriostatic performance is reduced, because the content of amino groups in the system is reduced after the content of chitosan is reduced, and the effect of inhibiting the synthesis of cell walls of microorganisms is weakened, so the bacteriostatic performance of the fabric in example 5 is reduced.
As can be seen from table 1, example 3 differs from example 6 in that: the mass ratio of chitosan, sodium periodate and tartaric acid in example 3 is 95:1:2.6, the mass ratio of chitosan, sodium periodate and tartaric acid in example 5 is 95:1.5:2.6, the dry-fast-elastic crease recovery angle and the dry-slow-elastic crease recovery angle in example 6 are both reduced, and the radial strength and the latitudinal strength are reduced, which is probably because the aldehyde group in the product is subjected to certain degree of intramolecular condensation after the ratio of sodium periodate is increased, so that the content of the aldehyde group is reduced, the effect of etherification addition of the aldehyde group and the hydroxyl group on the fabric is reduced, and the overall anti-wrinkle effect of the sample is reduced.
In example 3, the bacteriostatic rate of escherichia coli is 99.8%, the bacteriostatic rate of staphylococcus aureus is 99.7%, in example 6, the bacteriostatic rate of escherichia coli is 97.7%, and the bacteriostatic rate of staphylococcus aureus is 98.0%, in example 6, compared with example 3, the bacteriostatic performance is reduced, because the chitosan glycosidic bond is broken to be oxidized and degraded after the ratio of sodium periodate is increased, and the antibacterial effect of the system is reduced after the chitosan is dissolved, so that the whole antibacterial effect of the sample is reduced.
As is clear from table 1, the concentration of magnesium chloride in example 3 was 20g/L, the concentration of magnesium chloride in example 7 was 35g/L, and the dry-ballistic wrinkle recovery angle in example 7 were both decreased, and the strengths in the warp and weft directions were decreased, because the addition of excess magnesium chloride changed the acidity and alkalinity of the entire system, and decreased the reaction between chitosan and cellulose, and therefore, it was difficult to etherify the chitosan with hydroxyl groups on the fabric, and the wrinkle recovery angle was decreased, and the strengths in the warp and weft directions were also decreased.
As can be seen from Table 1, the amount of sodium hypophosphite added in example 3 was 1.3g, the amount of sodium hypophosphite added in example 8 was 3g, and the strength in the warp and weft directions was reduced in example 8 as compared with example 3, because the strength in the warp and weft directions was reduced because the fabric was hardened after the concentration of sodium hypophosphite was increased.
As can be seen from table 1, example 3 is different from comparative example 1 only in that, in comparative example 1, chitosan is replaced by sucrose, and in comparative example 1, the bacteriostatic performance is reduced compared with example 3 because sucrose has no amino group, and is difficult to bind with anions of cell walls of microorganisms such as bacteria, etc., and biosynthesis of cell walls of bacteria is difficult to inhibit, so that the bacteriostatic performance is significantly reduced.
As can be seen from table 1, example 3 differs from comparative example 2 only in that comparative example 2 replaces magnesium chloride with barium chloride, and comparative example 2 has a reduced dry-ballistic wrinkle recovery angle and reduced radial and latitudinal strength compared to example 3, which is probably because barium chloride has a reduced accelerating effect on the etherification addition reaction of aldehyde groups with hydroxyl groups on the stoppers, a reduced crosslinking effect, and a reduced adhesion effect of the anti-wrinkle agent, and thus the anti-wrinkle effect of the fabric is reduced compared to example 3.
As can be seen from table 1, the difference between example 3 and comparative example 3 is that tartaric acid is replaced by citric acid in comparative example 3, and the dry-fast-elasticity crease recovery angle and the dry-slow-elasticity crease recovery angle of comparative example 3 are both reduced, and the strength in the radial direction and the weft direction is reduced compared with example 3, which is probably because two secondary hydroxyl groups in the tartaric acid molecule can be esterified by carboxyl groups in stearic acid to form a kind of hexacarboxylic acid, which can improve the crosslinking effect between tartaric acid and the fabric, and the stability of citric acid is weaker, which is difficult to improve the stable crosslinking effect between citric acid and the fabric, so the anti-wrinkle performance of the fabric is reduced.
The present embodiment is merely illustrative and not restrictive, and various changes and modifications may be made by persons skilled in the art without departing from the scope of the present invention as defined in the appended claims. The technical scope of the present application is not limited to the contents of the specification, and must be determined according to the scope of the claims.
