Matters needing attention in the selection of textile instruments

After the reform and opening up, the development of domestic textile testing instruments (equipment) has basically met the requirements of the textile industry for the performance testing of textile raw materials, semi-finished products and finished products. A number of high-tech testing instruments (equipment) have been put on the market, and some models have been Or basically close to the international advanced level, providing a larger space for the selection of the domestic textile industry. In order to meet the needs of product quality inspection work, especially in the process of technological transformation of enterprises, many textile enterprises have strengthened the update of product quality inspection methods and the replacement of testing instruments (equipment), so as to maximize the quality inspection data of enterprises. To meet the timely, accurate and complete requirements, lay the groundwork for the development of enterprises and the growth of economic benefits. However, some enterprises often only consider its technical performance and cost-effectiveness in the selection of test instruments (equipment), and rarely or not at all consider the maintenance costs of test instruments (equipment) in the entire service life cycle and the selection and procurement process. A series of technical problems that need to be solved. Therefore, it is necessary to discuss—Below are several issues that enterprises should pay attention to in the process of purchasing test instruments (equipment). l The quality control contract of the order contract is an official document with legal effect reached by the buyer and the seller to achieve a certain economic purpose. It is also a legal means of quality control. In the event of a quality accident of testing instruments (equipment) or economic disputes, the contract is an important basis for adjudication and compensation. The contract should specify the origin, manufacturer's name, model specification, quantity, and technology of the purchased testing instruments (equipment). Parameters, quality assurance, packaging and transportation requirements, delivery time and their respective liability for breach of contract, etc. 2 The unpacking inspection of testing instruments (equipment) follows the development of enterprise productivity and the advancement of science and technology. Test instruments (equipment) products are becoming more and more diverse, and their performance structures are increasingly complex. It is sometimes difficult for users of test instruments (equipment) to judge their authenticity by their own abilities, especially for packaged products. In some cases, the product identification of the test instrument (equipment) and the relevant quality certificates have become one of the important channels for users to obtain the quality information of the product. Test instrument (equipment) name, model specification, measurement range, accuracy grade, production date, product number, product instruction manual, schematic diagram, assembly drawing, schematic diagram of parts, the standard number for manufacturing this type of test instrument (equipment), Production license mark and number, product quality inspection certificate, manufacturer's quality certification mark, manufacturer's name and detailed address, etc. This series of information is extremely useful in the use and maintenance of test instruments (equipment) in the future and when users establish technical files for them. 3. Performance and function of testing instruments (equipment) With the continuous application of new technologies, new processes and new materials in the textile industry, newer and higher requirements are put forward for textile testing content and testing methods. The performance and function of the test instrument (equipment) determine its cost-effectiveness, and more importantly, whether it can fully and accurately reflect the technical indicators of the measured object. This is especially important when comparing similar test instruments (equipment) from different manufacturers. The testing of yarn strength and elongation is an important technical index for evaluating yarn quality. my country issued and implemented in 1993“GB/T398—93”standard. Therefore, the textile industry urgently needs to use the electronic single-yarn strength tester in the detection of yarn strength and elongation, but the domestic automatic single-yarn strength tester at that time was due to the technical route. As a result, the reliability of the inspection quality of the whole machine and the reliability of the inspection results cannot meet the practical requirements. For this reason, quite a lot of textile instrument manufacturers have developed various types of semi-automatic single-yarn strength testers for users to choose from. So it is very important how to choose the applicable model among the many semi-automatic single yarn strength testers that touch the number. As a user, the first thing to know is what technical indicators need to be obtained to guide production through the single yarn tenacity test, and which type of semi-automatic single yarn tenacity tester can provide comprehensive yarn tenacity performance indicators. The semi-automatic single yarn strength tester developed by (Hong Kong) Co., Ltd. adopts the two-way control of single-chip microcomputer + PC machine. When the single-chip microcomputer is used to control the yarn stretching, the detection, data acquisition, calculation of technical indicators, result statistics and printout are completed by relying on the microcomputer. . The function configuration is the single yarn strength test method, and the LCD operation panel is used as the man-machine interface. Displays a large amount of information, can be recorded and browsed, and provides 12 test technical indicators. The data output method is in table format, printing single test value and batch statistical value, or displaying it on the LCD screen. Invalid data can be deleted arbitrarily. It has the function of saving data when power off, and the data report can be copied arbitrarily before power off.

It has become necessary for GESTER International Co.,Limited to continually cultivate, develop and update their skills to work successfully alongside high-tech.
