[summary of the invention]
For overcoming above-mentioned defect, the invention provides a kind of method of testing of splicing the mutual dyefastness of textile.This method of testing comprises the following steps performed in order: step S11, acquisition soak solution, and often liter of soak solution contains the agent of 3.5 ~ 4.5 grams of ECE standard wash; Step S14, by splicing textile sample be placed in the soak solution under predetermined temperature, soak 25 ~ 35 minutes; Step S17, from described soak solution, take out described sample; Step S21, dry described sample; Step S24, mutually dye is the most serious in described sample position are as the rating result of mutual dyefastness.
In the specification and claims, " performing in order " refers to that each step has sequencing when performing, and can not arbitrarily convert execution sequence between each step.But, between two steps, other steps can be added, such as, between step S17 and S21, other steps can be had.
In a preferred version, in step S14, described predetermined temperature is 35 ~ 45 degrees Celsius.
In a preferred version, in step S14, described predetermined temperature is 38 ~ 42 degrees Celsius.
In a preferred version, in step S21, sample described in the air drying being no more than 60 degrees Celsius.
In a preferred version, in step S14, described predetermined temperature is room temperature.
In a preferred version, after step S17, before step S21, also comprise step S19: by the fabric laminating of the different colours in described sample together, under 32 ~ 42 degrees Celsius, make its pressurized 11 ~ 14 kPas place 3 ~ 5 hours.
In a preferred version, in step S19, sample makes its pressurized 11.5 ~ 13.5 kPas place 3 ~ 5 hours under 32 ~ 42 degrees Celsius.
In a preferred version, in step S19, sample makes its pressurized 11 ~ 14 kPas place 3 ~ 5 hours under 34 ~ 48 degrees Celsius.
In a preferred version, in step S14, often liter of soak solution contains the agent of 3.8 ~ 4.2 grams of ECE standard wash.
In a preferred version, after step S17, before S21, also comprise: rinse described sample 1 ~ 3 minute with water.
After implementing method of testing of the present invention, the mutual dye situation of splicing textile can be judged.Through test of many times, this test result uses the result after the long period very close with splicing textile naturally.Therefore, method of the present invention can rapidly, effectively for test splicing textile mutual dyefastness, facilitate businessman select, design splicing textile, save the test duration of businessman, reduce the risk of businessman.

Step S14, by splicing textile sample be placed in the soak solution under predetermined temperature, soak 25 ~ 35 minutes.
Step S17, from described soak solution, take out described sample.
Step S21, dry described sample.
Step S24, mutually dye is the most serious in described sample position are as the rating result of mutual dyefastness.
After implementing method of testing of the present invention, the mutual dye situation of splicing textile can be judged.Through test of many times, this test result uses the result after the long period very close with splicing textile naturally.Therefore, method of the present invention can rapidly, effectively for test splicing textile mutual dyefastness, facilitate businessman select, design splicing textile, save the test duration of businessman, reduce the risk of businessman.
With reference to figure 2, the method for testing that one embodiment of the invention provides comprises the following steps:
Step S11, acquisition soak solution, often liter of soak solution contains the agent of 3.5 ~ 4.5 grams of ECE standard wash.Soak solution can be now with the current.Such as, take the ECE standard wash agent of 4 grams, be mixed with the soak solution of 1 liter with water, often liter of soak solution containing the agent of 4.0 grams of ECE standard wash can be obtained.Soak solution is preheated to 35 ~ 45 degrees Celsius for subsequent use.
Step S14, is placed in the soak solution of 35 ~ 45 degrees Celsius by the sample of splicing textile, soaks 25 ~ 35 minutes.Preferably, soak time is about 30 minutes.During concrete operations, sample and soak solution can be put into and wash cup, described sample can be stirred in immersion process, or wash cup, to strengthen clean result described in rotating.In yet another alternative embodiment, the temperature of soak solution is 40 ± 2 degrees Celsius.
Step S17, takes out described sample from described soak solution.
In step S20, rinse described sample 1 ~ 3 minute with water.In the present embodiment, rinse twice sample, each about 1 minute, add up to flushing about two minutes.
In step S21, dry sample.During concrete operations, step S20 use water first can squeeze out the water of sample, then draw unnecessary moisture with filter paper after rinsing sample.Then sample is suspended in the air being no more than 60 degrees Celsius and dries.
Step S24, mutually dye is the most serious in described sample position are as the rating result of mutual dyefastness.
With reference to figure 3, the method for testing of the mutual dyefastness of the splicing textile that another embodiment of the present invention provides comprises the steps:
Step S11, acquisition soak solution, often liter of soak solution contains the agent of 3.5 ~ 4.5 grams of ECE standard wash.Soak solution can be now with the current.Such as, take the ECE standard wash agent of 4 grams, be mixed with the soak solution of 1 liter with water, often liter of soak solution containing the agent of 4.0 grams of ECE standard wash can be obtained.Soak solution is cooled to room temperature for subsequent use.In the specification and claims, room temperature refers to 17 ~ 26 degrees Celsius, preferably 20 ~ 22 degrees Celsius.
Step S14, is placed in the soak solution under room temperature by the sample of splicing textile, soaks 25 ~ 35 minutes.Preferably, soak time is about 30 minutes.During concrete operations, can by soak solution and sample according to bath raio (50 ± 5): the preferred 50:1 of 1() be put into and wash cup, sample is soaked completely.
Step S17, takes out described sample from described soak solution, removes the surplus liquid on sample with glass bar folder.
Step S19, fits together the fabric face of different colours in sample, and horizontal, in the middle of two blocks of glass or acrylic resin board, makes it Vertical Compression 11 ~ 14 kPas (kPa) and continues 3 ~ 5 hours under 32 ~ 42 degrees Celsius.Preferably, sample makes its pressurized 11.5 ~ 13.5 kPas place 3 ~ 5 hours under 32 ~ 42 degrees Celsius, or under 34 ~ 48 degrees Celsius, make its pressurized 11 ~ 14 kPas place 3 ~ 5 hours.In the present embodiment, sample continues Vertical Compression (12.5 ± 0.9) kPa, and places 4 hours at the temperature of (37 ± 2) degree Celsius.
In step S20, rinse described sample 1 ~ 3 minute with water.In the present embodiment, rinse twice sample, each about 1 minute, add up to flushing about two minutes.
In step S21, dry sample.During concrete operations, step S20 use water first can squeeze out the water of sample, then draw unnecessary moisture with filter paper after rinsing sample.Then sample is suspended in the air being no more than 60 degrees Celsius and dries.
Step S24, mutually dye is the most serious in described sample position are as the rating result of mutual dyefastness.
In the present invention, during configuration soak solution, preferably use the tertiary effluent meeting GB/T 6682.When rinsing sample, also preferably use the tertiary effluent meeting GB/T 6682.
For the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
