Hello everyone, I am the president of the assessor who is in the cover.

Regardless of age, every girl cannot resist items full of girls. Today, I recommend this Hengyuan Xiangxiang cotton underwear, which is comfortable and breathable, and has a high face value.

Today, I recommend a cost -effective underwear, which will be evaluated from multiple directions such as appearance, quality, and experience.

Expert Reviews

There are 13 theme styles in the same paragraph, all of which are biased towards cute style. The elements include love, dots, stars, anime dolls, etc., to meet the needs of girls’ hearts. This is mainly based on love patterns, with pink color schemes and full of princess style.

According to the feedback of the trial personnel long test, the underwear is thin, and the cotton fabric is soft and breathable. The overall size is appropriate, but the waistband is fitted with the body but not meat.

Amateur trial

Experimental performance

1. Raise the ball and the ball test

Experimental explanation

1. During the phenomenon, the phenomenon of simulation of clothes is mainly simulated. During the daily wear, the phenomenon of hair balls appeared on the surface of the clothing due to continuous friction.

2. Experimental process: Take a round sample of 100cm2 from the tested clothing, load the sample on the yg502 round trajectory, refer to the national standard GB/T4802.1 to select the corresponding method and parameters, and exercise in the circular trajectory with the circular trajectory Methods to perform friction experiments. After obtaining the experimental sample, compare it in the standard rating box with the original and standard photos, respectively, and evaluate the grade 1-5 of the hair/kick level, the worst level 1 (the most serious kick), and the best level 5 is best. (There is no change on the surface).

Note: In view of the industry standards of some categories in the national standard, there is no mandatory requirement for the raising level of fabrics. The data obtained by this experiment is for reference only.

Conclusion: After many back and forth frictions of the trajectory instrument, there is no change on the surface of the underwear sample.

2. Color Interaction Test

Dry to dry, wet friction color accuracy test

1. Rubbing coloring the color fastness is one of the color fastness test. This experiment uses Y571D friction color fastness tester to simulate the daily use of clothing, which may occur.

2. Experimental process: Fix a sample of about 15cm*20cm on the friction tester platform. After setting the corresponding parameters, the standard friction cloth with a dry and 95%-100%humidity is performed. Dry/wet experimental sample.

3. Experimental samples use gray sample cards that comply with GB/T251, ISO 105/A03 standards, and compare level 1-5 under the standard light source to the color light box. Level 1 is the worst (the most severe color), and level 5 is the best (there is no color at all).

Conclusion: The dryness of the underwear and wet friction color is excellent, and the comparison rating reaches level 5. It is not easy to fade for daily wetting.

3. Hand washing color fastness test

Soak the clothes for about 15 minutes, simulate daily scrubbing, and observe whether the clothes have faded.

Add tap water to the washbasin, put the clothes and rub the clothes a few times, soak for about 15 minutes, take out the clothes and observe the color of the water.

Conclusion: After fully soaking for about 15 minutes, the panties did not have a floating color fading, and the first washing performance was good.

4. Breath test

1. The breathability determines the comfort of the clothing to a certain extent. In a relatively fixed environment, this experiment is at the same time simulated gas reached through the height of the clothes.

2. Choose three clothes of different thickness and detect them by third -party authoritative agencies. The breathability is: 183mm/s (good), 857mm/s (excellent), and 2136mm/s (excellent). Take these three different levels of samples, conduct the above small experiments test, and make three different photos of different breathable gas heights, which is convenient for experiments to compare instructions.

Note: The interpretation of the breathability of clothing samples, such as 2136mm/s, is 100 square centimeters of air pressure, the average rate of the gas through the 20 -square centimeter fabric sample is 2136 mm per second.

Conclusion: After testing, the height of the gas through the underwear can reach 3cm, which is slightly higher than the general level of 1.5cm.

Safety test report

This style is four outfits. The color is lively and cute. They are all elements such as love, pink, etc., especially for girls who are suitable for girls’ hearts.

The waist stitching high -bomb two -color strap, fitting without leaning.

The stitching position is stretching, large stretching, flat stitching, and not easy to spread on the seam edge.

The assessment of the underwear is over here. What kind of evaluation do you want to see? Welcome to comment ~
