antistatic agent 1.5 parts

0.03 part of citric acid

And 85 parts of water.

Each part of the antistatic agent comprises 1.5 parts of alkyl bis (alpha-hydroxyethylamine phosphate), 4 parts of polystyrene benzene sulfonic acid and 5 parts of alkyl dicarboxymethylammonium ethyl lactone.

The fabrics prepared in the above examples 1 to 5 and comparative example 6 were subjected to the moisture absorption, quick drying and other related performance tests, and the test items and test results are as follows:

test items	Water absorption/%)	Drip spread time/S	Evaporation Rate/(g/h)
				Example 1	156	3.6	0.24
Example 2	162	3.2	0.27
				Example 3	169	2.4	0.33
Example 4	166	2.8	0.31
				Example 5	160	3.0	0.26
Comparative example 6	121	5.2	0.19

Wherein, the water absorption test, the drip diffusion time test and the evaporation rate test are all performance test tests according to the test method of the national standard GB/T21655.1-2008.

And the water absorption test is to take the fabric with the size of 10cm x 10cm, place the fabric in deionized water for absorbing water, naturally sink the test sample after absorbing water, take out the test sample after soaking in water for 5min, naturally hang the test sample flatly and vertically, naturally drip water, and take out the test sample with tweezers for weighing when the test sample does not drip any more. The measured water absorption of the sample is equal to the ratio of the difference between the wetted mass and the original mass to the original mass.

The dropping diffusion time test is that the fabric with the size of 10cm x 10cm is placed on a platform, a proper amount of deionized water is sucked by a burette, then 0.2ml (about 1 drop) of deionized water is dropped on a fabric sample, and the distance between the mouth of the burette and the surface of the sample is not more than 1 cm. And (4) observing the diffusion condition of the water drops, recording the time required by the water drops to contact the surface of the sample until the water drops are completely diffused, if the water drops are slowly diffused and still are not completely diffused after a certain time, stopping the test, and recording that the diffusion time is longer than the set time.

And the evaporation rate test is to take the fabric with the size of 10cm x 10cm, test the dripping diffusion time of a sample, immediately weigh the mass after the test is finished, naturally and straightly hang the mass in the standard atmosphere, weigh the mass once every (5 +/-0.5) min until the change rate of the weighed mass is not more than 1% for two times, end the test, and calculate the evaporation rate of the waterQuantity: delta m_i＝m-m_i；E_i＝△m_i×100/m₀；

Wherein, Δ m_i-water evaporation amount, g;

m₀-the original mass of the sample, g;

m is the mass of the sample after being wetted by water dropping, g;

m_i-mass of the sample at a certain moment after wetting with water, g;

E_iwater evaporation rate,%.

The comparison of the data shows that the setting agent of the invention adopts the moisture absorption and sweat discharge agent, the water absorption rate is up to 156-169%, and the water diffusion time period after dripping is high in evaporation rate, so that the moisture absorption performance and the quick drying performance of the cloth finished product can be obviously improved; in contrast, the setting agent in comparative example 6 does not adopt a moisture absorption and perspiration agent, the water absorption rate of the prepared fabric is significantly reduced (only 121%), the dripping diffusion time is longer, and the evaporation rate is lower, which indicates that the fabric of comparative example 6 has lower moisture absorption and quick drying performance and weaker moisture absorption and perspiration effects than those of the fabric of the invention.

The fabrics obtained in the above examples 1 to 5 and comparative examples 1 to 5 were subjected to the performance tests related to smoothness, color fastness and the like, the test items and the test results are as follows:

the flatness grade is tested according to the national standard GB T13769-2009 test method for the flatness of the appearance of the washed textile evaluation fabric, wherein the SA-5 grade is equivalent to a standard sample plate SA-5, which shows that the appearance is the most smooth and the original flatness maintenance is the best; the SA-1 grade is equivalent to a standard sample SA-1 and shows that the appearance is the least smooth and the original appearance has the worst flatness retentivity; level 4.5 is intermediate between the standard template SA-4 and SA-5 levels.

The washing fastness grade is measured according to AATCC61 standard A2 item, household or commercial machine washing is carried out at the temperature of 38 +/-3 ℃, and the color change and staining change before and after washing are measured by a color counter. And the perspiration color fastness grade is tested according to AATCC 15-2009 standard and a perspiration resistance tester, and the color change and the staining condition change of the perspiration color grade are tested by using a color counter. The color fastness to sunlight grade was tested according to AATCC16-2004 standard and a xenon arc tester, and the color change was tested using a color counter (wherein the fastness to sunlight grade was eight, 1 is the worst, and 8 is the best).

The color change and the staining condition change grades are respectively as follows:

the test data show that the fabric prepared by the invention is soft and comfortable, is skin-friendly and breathable, has high moisture absorption, high volatilization speed of absorbed moisture, high color fastness, difficult deformation or decoloration in washing and high stability.

In the fabric treatment process, the prepared fabric has the flatness test of 4.5 grade or above, and compared with the comparative example 1 without performing the grey cloth pre-setting treatment, the fabric has relatively high flatness grade, even reaches SA-5 grade, while the comparative example 1 only reaches SA-3 grade; the method can perform the embryo fixing on the low-temperature spandex fiber in the gray cloth by performing the pre-setting treatment on the woven gray cloth, prevent the spandex fiber from having the phenomena of uneven shrinkage and excessive shrinkage in the subsequent dyeing process, avoid the undesirable phenomena of shrinkage, wrinkle, pull mark, chicken mark and the like of the fabric, perform the embryo fixing on the wool fiber, the acrylic fiber, the viscose fiber and the polypropylene fiber, prevent the problems of shrinkage or wrinkle and the like of the fiber in the subsequent dyeing, setting and washing in use, enable the fabric to be straight and smooth, achieve the effect of non-ironing, and have high flatness.

In the fabric treatment process, the prepared fabric has the washing fastness grade of 4.5 grade or above, and compared with the comparative example 1 without performing grey cloth pre-setting treatment, the fabric has the washing fastness grade which is relatively higher and even reaches 5 grade, which indicates that the grey cloth is subjected to the pre-setting treatment before dyeing, is beneficial to the stable dye uptake and attachment in the subsequent dyeing process, and improves the color fastness of the fabric. Compared with comparative example 2 (the washing fastness grade is only 3 grades) which only adopts the first dye solution to dye for one time and compared with comparative example 3 (the washing fastness grade is only 3 grades) which only adopts the second dye solution to dye for one time, the washing fastness grade of the fabric is relatively higher, which shows that the invention can effectively improve the dye uptake and the dye attachment stability of two dyes on the fabric by respectively adopting the first dye solution and the second dye solution to dye for two times, wherein, the dye uptake of the first dye solution on acrylic fibers is higher than that on viscose fibers, the first dye solution can be stably attached on the acrylic fibers, and the second dye solution on viscose fibers is higher than that on the viscose fibers, the second dye solution can be stably attached on the viscose fibers and respectively dyed for two times, so that the acrylic fibers and the viscose fibers on the 1 layer of the veil can be uniformly dyed, the dye has stable attachment and high color fastness.

If different fibers are dyed by a single dye, if only the cationic fibers are used for dyeing, the adhesive force of the dye to the viscose fibers is low, so that the dye-uptake of the viscose fibers is low, the dye of a product is easy to fall off from the viscose fibers in the subsequent process or use process, and the color fastness of the finished product is obviously reduced; similarly, if the reactive dye is adopted to dye the 1 layer of the veil, the adhesion of the dye to the acrylic fiber and the internal diffusion performance of the fiber are low, the dye is easy to fall off from the acrylic fiber in the subsequent process or the using process, and the color fastness of the finished product is obviously reduced.

The first dye liquor adopted by the invention has higher dye-uptake rate to acrylic fibers in the fabric, and the prepared fabric is not easy to fade or change color after being washed by water for many timesWhile the first dye liquor in the comparative example 4 does not adopt anhydrous sodium sulphate, the obtained fabric has obviously reduced washing fastness level, perspiration color fastness level and light fastness level and lower color fastness, which indicates that the first dye liquor of the invention adopts anhydrous sodium sulphate in which sulfate ions SO with negative charges₄ ^2-With NH in acrylic fibres³⁺The cationic dye is adsorbed on the surface of the fiber after combination, and the repulsive force borne by the cationic dye when the cationic dye is close to the surface of the fiber is greatly weakened, so that the energy resistance generated due to coulomb force is reduced, the combination of the dye and the fiber is promoted, and the dye-uptake rate is improved. Similarly, the same effect of accelerating the dyeing and improving the color fastness is also achieved for the anhydrous sodium sulphate in the second dye solution, and the ionized cation Na of the anhydrous sodium sulphate⁺The active dye with negative points is adsorbed on the surface of the viscose fiber with negative points, the fiber is wrapped by cations, and the repulsive force borne by the active dye with negative points is greatly weakened when the active dye with negative points is close to the surface of the fiber, so that the energy resistance generated by coulomb force is reduced, and the dye-uptake rate is improved.

The second dye solution adopted by the invention has higher dye-uptake to viscose fibers, the prepared fabric is not easy to fade or change color after being washed by water for many times, and the second dye solution in the comparative example 5 does not adopt Homekatol C, so that the washing color fastness level, the perspiration color fastness level and the light fastness level of the prepared fabric are obviously reduced, and the color fastness is lower.

The above-described embodiments are preferred implementations of the present invention, and the present invention may be implemented in other ways without departing from the spirit and scope of the present invention.
