Description

Crease-resistant finishing agent and linen fabric finishing process applying crease-resistant finishing agent
Technical Field
The application relates to the field of cloth finishing, in particular to an anti-crease finishing agent and a linen fabric finishing process applying the anti-crease finishing agent.
Background
The linen has the excellent performances of sweat clearing, separation, ventilation and cooling, but the anti-wrinkle performance of the linen is poor.
The linen is subjected to crease-resistant finishing by using a finishing agent containing formaldehyde at first, but the formaldehyde has great influence on the environment and the body of an operator.
At present, most researches are carried out on finishing the fabric by using polycarboxylic acid as a cross-linking agent and alkali metal salts containing phosphoric acid as a catalyst, and the researches show that the fabric finished by the method has good crease resistance with washability.
With respect to the related art in the above, the inventors consider that: when the phosphorus-containing compounds are discharged into streams and lakes along with the finishing wastewater, the phosphorus-containing compounds may become nutrients for accelerating the growth of algae, not only reduce the water quality, but also may exhaust dissolved oxygen required by fishes and aquatic organisms, thereby possibly causing damage to the ecological environment.

Meanwhile, the chitosan also has the effect of enhancing the antistatic property and the antibacterial property of the linen fabric.
The butane tetracarboxylic acid can enable the linen fabric to have a good crease-resistant finishing effect after the linen fabric is treated under the action of cyanamide, and the butane tetracarboxylic acid and the citric acid can enable the linen fabric to have a good crease-resistant finishing effect when the linen fabric is treated together.

The nonyl phenol polyoxyethylene ether and the dodecyl betaine have a good synergistic effect, and can promote the chitosan quaternary ammonium salt, the butane tetracarboxylic acid and the citric acid to be adhered to the linen fabric to a certain extent. And the nonylphenol polyoxyethylene ether, the dodecyl betaine and the chitosan quaternary ammonium salt have good synergistic effect, so that the antistatic property and the washing fastness of the linen fabric are enhanced to a certain extent.

step three: adding tetraacetylethylenediamine and sodium hydroxide into water, and stirring for 5-10min under the condition that the rotation speed is 100-200r/min to obtain the oxygen bleaching B agent.
By adopting the technical scheme, the hydrogen peroxide solution and the stabilizing agent in the oxygen bleaching agent are used as the oxygen bleaching A agent, the activating agent is used as the oxygen bleaching B agent, and when the oxygen bleaching agent is used, the oxygen bleaching A agent is firstly added into water, and then the oxygen bleaching B agent is added into the water, so that the hydrogen peroxide bleaching agent is safer during storage, and the loss of the hydrogen peroxide can be reduced; when the oxygen bleaching agent B is added into the water added with the oxygen bleaching agent A, the hydrogen peroxide can be quickly activated, so that the operation is relatively convenient and simple.
Preferably, in the step S3, the dye is dispersed in water to obtain a dye solution, wherein the mass fraction of the dye is 2-3% (omf), and the bath ratio is 1: (50-70); then 8-12g/L sodium hydrosulfite, 8-12g/L sodium hydroxide and 8-12g/L anhydrous sodium sulphate are added into the dye solution, and dyeing is carried out for 30-50min at the dyeing temperature of 55-65 ℃.

GB/T20944.3-2008, evaluation part 3 of antibacterial performance of textiles, namely an oscillation method, is adopted to test the antibacterial performance of the finished linen fabric. The test species had Escherichia coli, and the antibacterial rate was calculated by counting the number of surviving colonies. The bacteriostasis rate of the linen fabric to the strains is represented by R (%), and the calculation formula is shown as the following formula:
Ｒ=(1－C/F)×100%
c is the concentration of the bacterial liquid after finishing linen fabric oscillation contact with the bacterial liquid for 18h, CFU/mL; f is the bacterial liquid concentration, CFU/mL, of the unfinished linen fabric after being in contact with the bacterial liquid for 18 hours in a vibration mode. The test results are shown in table 9.

The CIE whiteness of the fabric was tested using a Data Color SP600 Color measuring and matching instrument. The fabric was folded into 4 layers (the grain direction on the fabric surface was as uniform as possible and the fabric was kept flat), measured at 3 different places of the fabric, and the average was taken as the whiteness value of the measured fabric, and the test results are shown in table 9.
Color fastness test
The color fastness to rubbing is determined according to GB/T3920-2008 "color fastness to rubbing test for textiles". The test results are shown in table 10.
Sixthly, washing fastness
Washing the finished linen fabric according to the 7A procedure in GB/T8629-2001, prebaking the washed sample in a vacuum oven at 50 ℃ for 2 hours, then placing the sample in a condition that the temperature is 20 ℃, the relative humidity is 35% and the ambient wind speed is 0.1m/s, balancing for more than 24 hours, and testing the changes of the wrinkle recovery angle and the antibacterial property.
