Description

Test method for mutual color fastness of spliced textiles

[Technical Field]

The present invention pertains to the field of textiles and, more particularly, to a method of testing the mutual color fastness of stitched textiles.

【Background technique】

The color fastness of the fabric is used to measure the firmness of the fabric color. A fabric with good color fastness can retain its original color after a long period of use without obvious fading.

Stitched textiles are all kinds of textiles that are spliced from fabrics of different colors. Stitching textiles are widely used, and splicing textiles are widely used in clothing, hats, shoes, and the like.

For splicing textiles, not only the color fastness of the various fabrics of the spliced textiles but also the mutual dyeing fastness of the various fabrics of the spliced textiles are considered. If the mutual dyeing fastness is not up to standard, the splicing of the textile will cause the color of the fabric to be dyed after a long time of use, which affects the aesthetics of the spliced textile and even affects the use of the spliced textile.

However, with the rapid changes in the business environment, it is impossible for merchants to design and manufacture stitching textiles in advance to test the mutual color fastness of the stitched textiles. Therefore, there is a need for a method that can test the mutual color fastness of spliced textiles relatively quickly.

[Summary of the Invention]

In order to overcome the above drawbacks, the present invention provides a test method for the mutual color fastness of a spliced textile. The test method comprises the following steps of performing the steps: step S11, obtaining the soaking liquid, containing 3.5 to 4.5 grams of ECE standard detergent per liter of the soaking liquid; and step S14, placing the sample of the spliced textile into the soaking liquid at the predetermined temperature. Soaking for 25~35 minutes; step S17, taking out the sample from the soaking liquid; step S21, drying the sample; and step S24, using the most severely dyed part of the sample as mutual coloring Degree of rating results.

In the specification and claims, 'ordered execution' means that each step has a sequence of executions, and the order of execution cannot be arbitrarily changed between steps. However, other steps may be added between the two steps, for example, between steps S17 and S21, there may be other steps.

In a preferred embodiment, in step S14, the predetermined temperature is 35 to 45 degrees Celsius.

In a preferred embodiment, in step S14, the predetermined temperature is 38 to 42 degrees Celsius.

In a preferred embodiment, in step S21, the sample is dried in air not exceeding 60 degrees Celsius.

In a preferred embodiment, in step S14, the predetermined temperature is room temperature.

In a preferred embodiment, after step S17 and before step S21, step S19 is further included: bonding the fabrics of different colors in the sample together, and pressing it at 11 to 14 kPa at 32 to 42 degrees Celsius. Leave it for 3~5 hours.

In a preferred embodiment, in step S19, the sample is subjected to a pressure of 11.5 to 13.5 kPa at 32 to 42 degrees Celsius for 3 to 5 hours.

In a preferred embodiment, in step S19, the sample is placed at a pressure of 11 to 14 kPa at 34 to 48 degrees Celsius for 3 to 5 hours.

In a preferred embodiment, in step S14, each liter of soaking liquid contains 3.8 to 4.2 grams of ECE standard detergent.

In a preferred embodiment, after step S17 and before S21, the method further comprises: rinsing the sample with water for 1-3 minutes.

After the test method of the present invention is carried out, the mutual dyeing of the spliced textiles can be judged. After many trials, the test results are very close to the results of stitching textiles after a long period of natural use. Therefore, the method of the invention can be used for testing the mutual color fastness of the spliced textiles quickly and effectively, facilitating the merchant to select and design the splicing textiles, saving the testing time of the merchant and reducing the risk of the merchant.

【detailed description】

Referring to Figure 1, the method for testing the mutual color fastness of a spliced textile provided by the present invention comprises the following steps:

In step S11, the soaking liquid is obtained, and each liter of the soaking liquid contains 3.5 to 4.5 grams of ECE standard detergent. Preferably, the immersion liquid contains 3.8 to 4.2 grams of ECE standard detergent per liter of the soaking solution. ECE standard detergents are commercially available. An ECE standard detergent containing no fluorescent whitening agent, the composition of which is as follows (mass fraction):

Sodium linear alkylbenzene sulfonate (average chain length C _{11.5 of} alkane carbon chain): 8.00 ± 0.02%

Polyvinyl ester (ethylene oxide number 14): 2.90 ± 0.02%

Sodium soap (chain length C ₁₂ -C ₁₆ : 13% to 26%; C ₁₈ to C ₂₂ : 74% to 87%): 3.50 ± 0.02%
