Overseas cotton textile market observation Vietnam's textile industry still has a lot of room for development and a huge demand for foreign investment, Vietnam Investment News reported on Aug. 25. According to statistics from the Foreign Investment Agency of Vietnam's Ministry of Planning and Investment, as of May 18, 2022, there were 2,787 valid FDI projects in Vietnam's textile industry with a total registered capital of US$31.3 billion. Nguyen Anh Tuan, deputy director of the Foreign Investment Department of the Ministry of Planning and Investment, said Vietnam's textile industry lacks connectivity in the value chain. Vietnam has a large trade surplus in yarn and garments, but also a large trade deficit in fabrics. The yarn produced is mainly for export, while domestic fabric only meets nearly 50% of the demand, making Vietnam import more than $10 billion of various fabrics every year. The fabric shortage is a potential market to attract foreign investment in Vietnam...

Oxygen Index Tester - Test procedure for surface combustion method

Oxygen Index Tester - Test procedure for surface combustion method Instrument structure: A complete test of the burning properties of insulating liquids -  Oxygen Index Tester  consists of a quartz glass combustion cylinder, test disc, test disc support, flow measurement and control device, ignition source, paramagnetic or chemical oxygen sensor, timer, smoke exhaust system. Test methods: (1) wick method in the specimen immersed in an inert material (such as glass wire, asbestos wire, etc.) made of wick , the Ignition only let the wick ignite . (2) surface combustion method, also known as the wickless method, ignition, the igniter against the entire surface of the liquid specimen, so that the entire surface are burning.

What are the standards that Taber Rotary Abraser 5135 & 5155 meets? The following is a partial list of standards to which the  Taber Abrasion Tester  conforms: AA-56032D "Trade Description Ink, Marking, Epoxy Base ANSI / ISEA 105 "American National Standard Hand Protection Selection Criteria ANSI / SAE Z26.1 "Safety Glass for Glazing Motor Vehicles and Motor Vehicle Equipment ANSI INCITS 322 "Card durability test method AS / NZS 1580.403.2 "Paint and Related Materials - Test Methods AS / NZS 4266.20 "Recycled Synthetic Panels - Test Methods AS 2001.2.28 "Test Methods for Textiles ASTM B607 "Standard Specification for Autocatalytic Nickel Boron Coatings for Engineering Purposes ASTM B733《Standard Specification for Autocatalytic Electroless Nickel-Phosphorus Coatings on Metals ASTM B893《Standard Specification for Hard Coating Anodizing of Magnesium for Engineering Purposes ASTM C1353《Standard Test Method for Determination of Abrasion Resistance...

Taber Abrasion Tester test operation method

Taber Abrasion Tester test operation method How does the Taber type abrasion tester perform the friction test?   From the outside, it is not very obvious, but the equipment is actually used to test the abrasion resistance of leather and plastic, fabric, floor tiles, and plywood by rotating and rubbing different types of friction wheels on the specimen (wheel numbers include H18, H22, CS10, CS17, CS32, CS33).   It can be seen that the Taber type abrasion tester relies mainly on rotary grinding, so that it is used to test the abrasion resistance of leather and plastic materials by using different types of friction wheels to rotate on the sample through the test disc. This requires us to choose the set of weights applicable to the standard. The abrasion index has a formula which is: weight of abrasion loss / number of test rotations * 1000 The results of the test are used to identify the properties of the test material and to check the weight loss on the outer surface of the samp...

Did you know? Crash test dummies that are more expensive than cars

Did you know? Crash test dummies that are more expensive than cars At the end of each crash test, professional engineers will give the crash vehicle a score. The reference basis for scoring, in addition to the assessment of the damage to the vehicle, but also to the car "personnel" injury assessment, at this point, that is the role of the crash test dummies. Crash test crash test dummies are based on a large number of cadaver test research (this is also the crash test crash test dummies research and development cycle is long, one of the reasons for the high price), crash test dummies are mostly made of metal and plastic, the chest cavity is made of steel, the shoulder blade is made of aluminum, the pelvis is made of plastic. The cost is up to about $ 40,000, if coupled with the sensor supporting equipment, the cost is up to $ 60,000 to $ 70,000. Why crash test dummies are widely used in automotive crash testing? In the early car crash test, the staff will personally participa...

The mysterious structure of ICI pilling snagging tester

The mysterious structure of ICI pilling snagging tester ICI pilling snagging tester's 2 main structures:   1. the movement of the grinding head:   ICI pilling snagging tester  in the speed of the abrasive head trajectory, directly affects the effect of friction between the specimen and the abrasive. This instrument adopts JX 07 capacitor motor, the speed is reduced by a worm gear installed in the gearbox, the speed ratio is 1: Han, so that the grinding head obtains a speed of 60 revolutions per minute. The size of the trajectory. The trajectory of this apparatus selected 40 mm diameter circle (countless composite circle) when toggling the forward and reverse switch, can be obtained clockwise or counterclockwise trajectory. Test that: this circular motion trajectory, with symmetry, so the specimen does not have the provisions of the latitude and longitude, the direction of the specimen clamp sample, there are no special requirements and to ensure the uniformity of friction...

Textile testing instruments purchase and use of the 3 points

Textile testing instruments purchase and use of the 3 points In order to ensure that the  textile test instrument  measurement results are accurate and consistent, so that its value is stable within a certain tolerance range, the purchase and use of instruments, must pay full attention to it should be good measurement performance, the necessary measurement verification. For example. 1. an instrument often has several ranges to choose from, the general range of the indicated value of the instrument has a large error at both ends, so according to the different test objects, should choose a reasonable, moderate range of the instrument. 2. The precision of the instrument (referred to as accuracy) is a comprehensive reflection of the random error and systematic error of the instrument, in order to obtain the correct measurement results at the same time, you must choose the appropriate accuracy level of the instrument 3. Instrument reproducibility indicates that under different meas...
