Example 2: scarf testing method
For the scarves designed and obtained according to the method of example 1, the corresponding indexes of the same piece of scarves were measured before washing and after washing and drying, respectively, and the color fastness and the yellowing of the scarves were calculated and obtained. After pretreatment and washing, the corresponding dimension of the same scarf shrinkage test standard line layer 4 is measured in a standard tray, and the shrinkage of the scarf is calculated and obtained, wherein the specific operation method is shown as follows.
Color fastness testing method
The measuring instrument for color fastness is a spectrophotometer, and the spectrophotometer used is a spectrophotometer of a Datacolor600 model produced by Datacolor company.
Color fastness test method referring to fig. 5, in the figure 5, a circle in a color fastness test layer 3 is a test point, the reflectance of the test point of the silk scarf color fastness test layer 3 after washing and drying is measured by the spectrophotometer, a light source D65/10 degrees and a wavelength of 400nm-700nm are adopted, and the color difference value of the silk scarf is calculated according to the reflectance.
1. The calculation formula is as follows:
the color difference value of the scarf color fastness test layer 3 is calculated according to the following formula:
F＝|fS-fW|×100％
in the formula:
f, the color difference value of the real silk fabric, which is expressed by percentage (%);
fS-the washed reflectance of the blue scarves color fastness test layer 3, expressed in percent (%);
fWblue scarves color fastness test layer 3 pre-wash reflectance, expressed in percent (%).
2. Color fastness evaluation of scarves
The color fastness of the scarves color fastness test layer 3 was confirmed by the color difference before washing, after washing and drying. The color difference is divided into five integral color fastness grades, namely 5, 4, 3, 2 and 1 according to the appearance. And adding a half-grade in every two grades, namely 4-5, 3-4, 2-3 and 1-2, and expanding and compiling into a nine-grade card. Before the silk scarf is not tested by a real silk washing program, the reflectivity before each washing is the natural color, and after the silk scarf is washed, the color difference of the color fastness test layer 3 of the silk scarf gradually changes. The greater the color difference, the lower the color fastness rating, which is determined in table 1 for the scarves color fastness test layer 3.
TABLE 1 scarves color fastness rating
| Color fastness grade | Value of Y color difference |
| 5 | 0 |
| (4-5) | 2.2 |
| 4 | 4.3 |
| (3-4) | 6.0 |
| 3 | 8.5 |
| (2-3) | 12.0 |
| 2 | 16.9 |
| (1-2) | 24.0 |
| 1 | 34.1 |
As above method for measuring the color fastness of the color fastness test layer 3 after the washing of the silk scarf, when the washing is performed K times, the color fastness after the washing K time relative to the unwashed silk scarf can be calculated according to the reflectance before the first washing and after the washing K time and the drying according to the same principle and formula; the color fastness caused by the Kth washing can also be calculated according to the reflectivity after the Kth-1 washing and drying and the reflectivity after the Kth washing and drying.
The method can also be used for testing the pretreatment method of the silk scarf in the water shrinkage test method, namely, the reflectivity of the silk scarf is measured before washing, the reflectivity of the color fastness test layer 3 of the silk scarf is measured after pretreatment and washing, and the color difference value is calculated according to the two reflectivities.
Second, yellowing degree testing method
The index of measuring the degree of yellowing uses a reflectance meter, the reflectance meter is a spectrophotometer of a Datacolor600 model produced by Datacolor company, the reflectance meter is used for measuring the reflectance of the test point of the measuring layer 2 of the degree of yellowing of the scarves before washing and after washing and drying, a light source D65/10 degrees, the wavelength is 400nm-700nm, and the calculation formula of the specific degree of yellowing is as follows:
T＝F1/F0×100％；
wherein, F0The reflectance value of the scarves before washing of the layer 2 is measured as the degree of yellowing;
F1the reflectance value of the scarves after washing and drying of the yellowing test layer 2 is shown;
t is the degree of yellowing of the scarf yellowing test layer 2.
In order to examine the change of the yellowness of the scarfskin washed by the yellowness test layer 2 for K times, the yellowness of the scarfskin washed by the yellowness test layer 2 for K times can be calculated by dividing the reflectance value of the scarfskin washed by the yellowness test layer 2 before the first washing by the reflectance value of the scarfskin washed by the scarfskin yellowness test layer 2 for K times.
In order to make the calculation of the yellowing factor more accurate, the reflectance values of the yellowing factor test layer 2 before and after washing can be respectively measured on the N pieces of scarves subjected to parallel washing treatment, and the average yellowing factor can be calculated, wherein the specific calculation formula of the average yellowing factor is as follows:
TT＝FT1/FT0×100％；
wherein, FT0Test layer 2 for yellowness of N pieces of scarves before washingThe sum of the reflectance values;
FT1the sum of the reflectivity values of the washed N scarf yellowing test layers 2;
TTthe average yellowness of layer 2 was tested for yellowness of N scarves.
In order to calculate the yellowing factor more accurately and examine the change condition of the yellowing factor of the N scarves washed by the yellowing factor test layer 2 for K times, the average yellowing factor of the N scarves washed for the K time yellowing factor test layer 2 can be calculated by dividing the sum of the reflectance values of the N scarves washed for the K time yellowing factor test layer 2 by the sum of the reflectance values of the N scarves washed for the K time yellowing factor test layer 2 before the first washing.
The method can also be used for testing the pretreatment method of the silk scarf in the shrinkage test method described below, namely, the reflectivity of the silk scarf yellowing test layer 2 is measured before washing, the reflectivity of the silk scarf yellowing test layer 2 is measured after pretreatment and washing, and the yellowing degree is calculated according to the two reflectivities.
Third, shrinkage testing method
Pretreatment of scarves
