4 kinds of common random tumbling pilling test method 4 common random tumbling pilling test methods： 1.Tumbling pilling test： Test instrument:  Random Tumble Pilling Tester . In this test method, fabric specimens are turned over in a cylindrical test chamber lined with cork and stirring bars, and the specimens rub against each other and against the chamber walls. The motion of the fabric specimens is random and the processing time varies. The advantage of this method is that its random motion is very similar to the force situation of the fabric in the actual wearing process, but the fabric specimen will be stuck by the stirring bar during the test, so that the fabric treatment strength is not uniform in time, so the repeatability of the experimental results is poor. The test method is mainly used in DIN53867 and ASTM3512 standard. 2.Round track pilling meter test method： Test instrument:  Fabric gsm round cutter The test method, the first use of nylon brushes, under a certain pressure

Abrasion resistance test and influencing factors of woven fabrics   Martindale abrasion resistance instrument  for woven fabrics, knitted fabrics, woolen textiles, artificial leather, synthetic leather, etc. in the pressure of abrasion resistance and pilling degree test, applied to a variety of industries such as textiles, footwear, clothing.   Test principle.   1. Round fabric specimens under a certain pressure, and standard abrasives according to Lissajous (Lissajous) curve of the trajectory of mutual friction, resulting in specimens broken, the number of broken specimens wear resistance to express the wear resistance of the fabric.   2. Round specimen and the same material fabric under a given pressure, to Lissajous graphical motion trajectory for friction, to reach the specified number of revolutions, the evaluation of the specimen pilling grade. For different fiber raw materials fabric, wool woven fabric wear resistance is good, viscose woven fabric wear resistance is poor, polyes

What should you to pay attention to before using textile testing instruments? Before each textile testing instruments run must do testing, press the reset switch, let the instrumentation restart, otherwise the data processing method way will be displayed incorrectly; instrumentation calibration and installation Zero key, all contain the effect of automatic zeroing of the force measuring sensor, warmly reminded to start the instrumentation to keep on the combination of fixture in addition to its own net weight, no all other additional support, otherwise tare strictly prohibited, will lead to inaccurate detection. will lead to the inaccuracy of the test. textile testing instruments input set basic parameters, should be carried out before the start of the test, otherwise, will lead to incorrect data processing methods, in the fully automatic management process of textile instruments, built-in test values to distinguish the operating procedures, the data processing of obvious errors. Will

How to set the time and temperature of vacuum drying oven? : Drying oven use environment requirements:  1. Temperature: 5～40℃ b) Relative humidity: ≤85%rh c) Power supply voltage: ac220v±10% 50hz d) No strong vibration and corrosive gas influence around   After the commissioning of vacuum degree, you can do the following operations:   2. Open the power supply of vacuum box, the power indicator should be on (6090 and 6210 type should open the switch of temperature control instrument respectively), the temperature control instrument will be self-tested, the pv screen will show the measured temperature inside the working chamber, the sv screen will show the temperature set at the factory. Temperature control instrument at and heat and other lights should be on, indicating that the instrument into the working state of heating.    3. modify the set temperature 1. press the function key (set) of the temperature controller; pv screen display sp characters, the key head button can be used to m

Shock: Tensile testing machines can do more than you thought The tensile testing machine is not just a simple tensile test. It is the same model as the universal machine. It can do other tests universally by changing different fixtures. But how to measure the test data of the tensile testing machine? Explain in detail for you. The measurement is done through a load cell, an amplifier and a data processing system. The commonly used load cell is a strain gauge sensor. The so-called strain gauge sensor is composed of strain gauges, elastic elements and certain accessories (compensation elements, protective covers, wiring sockets, loading parts), which can convert certain mechanical properties into electrical output devices. There are various types of strain gauge tension and pressure sensors at home and abroad, mainly including cylindrical force sensors, spoked force sensors, S double-connected hole sensors, and cross beam sensors.

[Textile Testing] Textile antistatic test methods 01. Friction charged voltage measurement method   Principle: Under certain tension conditions, make the sample and standard cloth rub against each other, to the highest voltage generated at this time and the average voltage evaluation. Note: When the sample front and back electrostatic properties are different, both sides should be measured.   02. Friction charged charge measurement method   After the sample is rubbed with static electricity, it is put into a Faraday cylinder and the total amount of charge is tested. 03.Impedance measurement method   Select two points at a certain distance on the surface of the specimen, contact them with electrodes, and test the inter-pole resistance. It is commonly used in the evaluation of antistatic performance of dust-free clothes, computer room antistatic clothes and carpets.

Textile color fastness testing notes Raw material testing   It refers to the yarn used to weave the fabric, and the fiber made of yarn, etc. These are the more original materials, and their characteristics will affect the quality of their semi-finished products. Therefore, some of their characteristics need to be tested. The testing of raw materials is generally done only for the most important characteristics, such as the length of cotton fibers, the deformation of shaped fibers, the strength of chemical fibers, etc. Fabric testing   It refers to the testing of fabrics according to their characteristics or the basic requirements made by them or the characteristics of garments, such as: color fastness testing, physical testing, chemical testing, ecological testing, burning performance testing and functional testing, etc. The subjects of fabric testing are mostly fabric suppliers, buyers and production technology R&D departments.

PPE Wearable Cooling & Dehumidifying makes you fearless of humidity PPE Wearable Cooling & Dehumidifying Equipment  is very compact, it uses the principle of airflow circulation to take away the moisture from the surface of the body. The PPE Wearable Cooling & Dehumidifying looks like a small, flat backpack, and the humid airflow from both sides of the body is filtered through the internal dryness of the dehumidifier and then re The airflow of moisture from the sides of the body is filtered through the internal drying of the dehumidifier and then returned to the user, bringing a full day of refreshment. The dehumidifier is very portable, after a thin jacket outside basically can not be seen inside the "hidden" (do not mind the two airflow tube shape of friends can also be worn directly), and the inside of a constant stream of fresh air will drive away the moisture around you. Like cycling, running, sports friends can also carry  PPE Wearable Cooling & Dehumidi
