[0002] With the increasing popularity of automobiles, the application of stain-resistant fabrics and suede microfiber synthetic leather in automotive interiors is gradually expanding. Currently, the main standard for evaluating the stain resistance of textile fibers is GB / T30159.1-2013 "Test and Evaluation of Stain Resistance of Textiles - Part 1: Stain Resistance," which includes liquid staining and solid staining methods. Liquid staining tests are conducted on oily stains such as peanut oil, soy sauce, coffee, and fruit juice, while solid staining tests are performed on dust containing high-pigment carbon black using a specific test cylinder device to evaluate the color change level. However, there is no simple and suitable method to test the stain resistance of fabrics against particulate pollutants (such as soot and sand commonly encountered in daily use). Therefore, designing a simple and effective method for testing the stain resistance of textile fibers against particulate pollutants has broad application scenarios. Summary of the Invention

[0037] Example 1

[0038] Figure 1 This is a flowchart of a textile stain resistance test provided by an embodiment of the present disclosure. This embodiment of the present disclosure is applicable to situations where users are provided with textile stain resistance tests. The method can be executed by a textile stain resistance test device, which can be implemented in the form of software and / or hardware. Optionally, it can be implemented by an electronic device, such as a mobile terminal, a PC, or a server.

[0039] like Figure 1 As shown in the embodiments of this disclosure, a method for testing the stain resistance of textiles may specifically include the following steps:

[0040] S110, Acquire particulate pollutants, test textiles and friction materials.

[0041] In this embodiment, particulate pollutants can be solid or liquid particles suspended in the air, such as soot, sand, etc. The test textile can be a woven product used for testing, such as textiles or suede microfiber synthetic leather. The friction material can be undyed standard polyester fabric conforming to GB / T 7568.4, or one of wool fabric, nylon fabric, or nettle fabric.

[0042] Specifically, the study involves obtaining particulate pollutants and testing textiles and friction materials. Particulate pollutants can be obtained through preparation.

[0043] Optionally, particulate pollutants can be obtained by: burning a set combustible material to obtain ash after combustion; or filtering the ash to obtain particulate pollutants.

[0044] In this embodiment, the combustible material can be a segment of tobacco with a length of 10mm.

[0045] Specifically, the aforementioned combustible material is placed in a crucible, and a predetermined volume of ethanol is added as the combustion medium. The mixture in the crucible is then ignited in a fume hood and kept burning completely. The ash from the complete combustion is slowly poured from the crucible into a sieve with a predetermined aperture, and after thorough shaking, it is sieved. The ash filtered through the sieve is collected as particulate contaminants. The predetermined volume can be 5 ml, and the predetermined aperture can be 100 μm.

[0046] S120. Pre-treat the test textile to obtain the pre-treated test textile.

[0047] Specifically, the test textiles are first left to stand for a set time, and then cut to obtain a test textile of a set size.

[0048] Optionally, the pretreatment of the test textile can be carried out by: letting the test textile stand still for a first set time; and cutting the test textile after standing to obtain a test textile of a set size.

[0049] In this embodiment, the set duration is a preset duration, which can be 48 hours. The set size can be a square with a side length exceeding 100mm.

[0050] Specifically, the test textile can be placed in a standard ambient temperature of 23±2℃ and relative humidity of 45%-55% for 48 hours. After placement, the test textile is cut into a square sample with a set side length exceeding 100mm, ensuring that the sample surface is free of contamination, wrinkles, or other undesirable appearance. The sample should be cut from a point at least 20cm away from the test textile to obtain a test textile of the set size.

[0051] S130. The pretreated test textile is rubbed with a friction material to obtain a static-charged textile.

[0052] In this embodiment, the electrostatic textile can be a textile in which the contact surfaces of two materials separate after friction, and the excitation energy of electrons or ions occurs between their surfaces, resulting in the accumulation of charge.

[0053] Specifically, the pretreated test textile is rubbed with a friction material, and after a set number of rubs, an electrostatic textile is obtained.

[0054] Optionally, the pretreated test textile is rubbed with a friction material to obtain an electrostatic textile. This can be achieved by rubbing the friction material and the pretreated test textile continuously for a set number of times.

[0055] Specifically, the aforementioned friction material is kept in horizontal contact with the pretreated test textile, and the surface of the pretreated test textile is continuously scraped in the same direction a set number of times under a set pressure to obtain an electrostatic textile.

[0056] S140. Contacting static-charged textiles with particulate contaminants to obtain soiled textiles.

[0057] Specifically, the friction surface of the aforementioned electrostatic textile is placed in a petri dish made of insulating material containing particulate contaminants, and left to stand for a set time to obtain a soiled textile. The set time can be 5 seconds.

[0058] Optionally, the method of contacting the electrostatic textile with particulate contaminants to obtain contaminated textiles can be: placing the particulate contaminants in a petri dish made of insulating material; and leaving the electrostatic textile on the petri dish for a second set time to obtain contaminated textiles.

[0059] In this embodiment, the surface dish can have an inner diameter of 100±0.5mm and a height of 10±0.5mm, and be made of an insulating material, such as glass, polycarbonate resin, or polymethyl methacrylate. The second set duration is a preset duration, such as 5 seconds.

[0060] Specifically, the collected particulate matter is placed in a petri dish, with the height of the particulate contaminants reaching half the height of the petri dish. The friction surface of the electrostatically charged textile is then placed on the petri dish and left to stand for a set time to obtain the soiled textile. The set time can be 5 seconds.

[0061] S150. To evaluate the staining of textiles and obtain the stain resistance rating of the tested textiles.

[0062] In this embodiment, the antifouling rating can be a rating of the ability to prevent contamination by pollutants, which can be evaluated based on the area of ​​the contaminated area and the degree of discoloration.

[0063] Specifically, the area of ​​the stained area on the stained textile is obtained, the color of the stained area is compared with a set color chart to obtain the color change level, and based on the area of ​​the stained area and the color change level, the stained textile is evaluated according to the set mapping relationship between the area of ​​the stained area, the color change level and the stain resistance level to obtain the stain resistance level of the tested textile.

[0064] Optionally, the method for evaluating the staining of textiles and obtaining the stain resistance level of the tested textiles can be as follows: obtain the area of ​​the stained area on the stained textiles; compare the color of the stained area with a set color chart to obtain the color change level; and determine the stain resistance level of the tested textiles based on the area of ​​the stained area and the color change level.

[0065] Specifically, the area of ​​the stained area on the stained textile is obtained, the color of the stained area is compared with a set color chart to obtain the color change level, and the stain resistance level of the tested textile is determined based on the area of ​​the stained area and the color change level.

[0066] Optionally, the method for determining the stain resistance level of the test textile based on the area of ​​the stained area and the color change level can be: obtaining the mapping relationship between the area of ​​the stained area, the color change level and the stain resistance level; and determining the stain resistance level corresponding to the area of ​​the stained area and the color change level of the test textile based on the mapping relationship.

[0067] In this embodiment, the mapping relationship between the area of ​​the stained area, the color change level, and the stain resistance level is obtained, and the stain resistance level corresponding to the area of ​​the stained area and the color change level of the tested textile is determined based on the mapping relationship.

[0068] For example, the mapping relationship can be as follows: the anti-fouling level can be set to 5 levels, where level 1 is the worst anti-fouling effect and level 5 is the strongest. The area of ​​the stained area can be set to four cases: the entire test area, the stained area exceeding half the test area, the stained area less than half the test area, and the test area completely unstained. The discoloration level can be divided into 5 levels. For example, the area of ​​the stained area can be set as follows: the entire test area is anti-fouling level 1; when the stained area exceeds half the test area and the discoloration level is less than or equal to 2, it is anti-fouling level 2; when the stained area is less than half the test area and the discoloration level is less than or equal to 2, it is anti-fouling level 3; when the stained area is less than half the test area and the discoloration level is greater than or equal to 4, it is anti-fouling level 4; and when the test area is completely unstained, it is anti-fouling level 5. If the staining phenomenon is between two levels, 0.5 can be used to represent the level. For example, when the stained area is less than half the test area and the discoloration level is 3, the anti-fouling level can be considered 3.5.

[0069] This invention discloses a method for testing the stain resistance of textiles. The method includes: acquiring particulate pollutants, test textiles, and a friction material; pretreating the test textiles to obtain pretreated test textiles; rubbing the pretreated test textiles with the friction material to obtain electrostatically charged textiles; contacting the electrostatically charged textiles with particulate pollutants to obtain soiled textiles; and evaluating the soiling of the soiled textiles to obtain the stain resistance level of the test textiles. Using this method, the charged test textiles adsorb solid particulate stains, and the ability of the textiles to resist solid stains is determined by evaluating and comparing the adsorbed solid stains on the material surface.
