Sample Prepare Laboratory Sample - As a laboratory sample, randomly select a quantity of buttons, approximately 100 to 200, from a carton and from contained boxes, that adequately represents the material, from which test specimens may be selected. Test Specimens - Randomly select 15 buttons from the laboratory sample for testing. If test specimens are submitted for preproduction approval, testing ...
1. Sensor pressure value is not jumping or the value is too large Check if the motherboard sensor is loose. If it is loose, please insert it firmly. If the instrument is not turned on, please click the clear button on the working interface. 2. There was no significant increase in pressure during the experiment: Make sure the sensor is cleared before the experiment starts. Check if the motherboard ...
It is strictly forbidden to put debris in the color light box to avoid damage to the neutral gray of the inner wall, which will cause errors in color matching. Do not start the lamp too frequently, otherwise it will affect the life of the lamp. The distribution of various light sources in the machine must be installed according to the "lamp distribution map" to obtain a uniform and sufficient ligh...
In a standard laboratory, spray distilled water on the sample through a funnel, and compare the rating with a waterproof standard sample. Common test standards are American Standard: AATCC 22; European Standard: ISO 4920. There are three types of anti-splashing water: ordinary waterproof (WaterRepellent, abbreviated as: W/R), waterproof water (DurableWaterRepellent outdoor fabric industry is commo...
The production and manufacturing process of textiles are relatively complicated. The clothing that people wear actually undergoes countless processes before they change from cotton or yarn into fabric products. Among them, there are hundreds of types of textile and clothing testing. , For example, to test the performance of air-permeable fabrics. Under the specified pressure difference condition, ...

1. The sample is parked in the laboratory environment for more than 8 hours 2. Cut a sample at the flat part of the sample, if it is an insole, it should be cut to the transfer part 3. Remove the load and load shaft from the testing machine 4. Remove the top plate and test fixture 5. Device for the sample: Loosen the fixing ring on the test fixture, remove the sample tablet, place the sample in th...
Hydrostatic pressure test is a common method to assess the water resistance of fabrics. GB / T 4744—2013 "Determination of Water Impermeability of Textile Fabrics" Hydrostatic Pressure Test "specifies a hydrostatic test method for testing the water impermeability of fabrics. Mainly suitable for tight fabrics, such as canvas, linoleum, tent cloth and rainproof clothing cloth, etc. The test method i...
1. Choice of grey cloth The dyeing fabrics of the same variety specifications, due to the quality of the yarns and the different weaving methods, will also cause the difference in wet rubbing fastness of the dyed fabrics processed by the same process conditions. Therefore, it is preferable to select a grey fabric with excellent yarn quality, uniform yarn count, and smooth surface. 2. Pretreatment ...
1. Dye performance Some water-soluble dyes, such as reactive dyes, contain water-soluble groups that facilitate dye dissolution and dyeing during the dyeing process. Some poorly water-soluble dyes, such as vat dyes, are mechanically padded to the fibers in a suspension state during continuous padding, and are reduced in steam to become water-soluble dye leuco. The fibers are then oxidized, boiled,...
