What are the cutting edge technologies used in the field of textile testing?

Name a textile inspection device and briefly explain the principle of the test.

One of the textile testing equipment is the yarn strength tester. It is mainly used to measure the breaking strength of yarns and fabrics. The working principle of the instrument is:

The yarn or fabric is fixed at both ends of the tester, and then the breaking strength of the yarn is measured through the tester's sensor. When the yarn breaks, the front balance sensor can detect the breaking force and calculate the breaking strength.

Textile physical inspection: refers to the use of various instruments, meters, equipment, measuring tools and other testing means to measure or compare the physical properties or physical quantity of various textile products, and systematically sort out and analyze, in order to determine the physical properties and quality of textiles is an inspection method.

Textile chemical inspection: refers to the use of chemical testing technology and equipment to determine the chemical characteristics, chemical composition and content of textiles through the analysis and testing of textile samples.

Under certain conditions, the producer, the buyer or a third party shall inspect the quality, specifications, weight, quantity, packaging, safety and health of the goods in accordance with the contract, standards or relevant laws, regulations and practices at home and abroad with the help of certain means and methods, and make a judgment on whether the goods are qualified or whether they have passed the acceptance. or in order to safeguard the legitimate rights and interests of buyers and sellers, avoid or resolve disputes over various risks and losses and division of responsibilities, and facilitate the handover and settlement of commodities and issue various relevant certificates for business activities.

Quality: Refers to the sum of characteristics that reflect an entity's ability to meet explicit and implicit needs. In terms of the most important performance and function of textiles in use, it should be aimed at fully meeting the requirements of users and consumers.

Quality certification: refers to the activities that are confirmed by a third-party certification body according to product standards and corresponding technical requirements, and through the issuance of certification certificates and certification marks, to prove that a product meets the corresponding standards and technical requirements. It is an effective method of managing product quality in the world.

The certification process is rigorous, fair and scientific, and users no longer have to go through unnecessary repetitive inspections.

Quality supervision: refers to the activities of supervising the quality of products and services and the conditions for enterprises to ensure quality in accordance with ** laws or regulations.

Quality control: It mainly refers to the control of the specific properties of the product in order to ensure that it meets the set specifications and technical conditions.

Performance: It reflects the needs of customers and society and the functions specified in the product, which can be divided into two aspects: performance and appearance. It refers to the specifications and technical requirements of textiles, aesthetics, applicability, reliability, safety, environment and service life.

1. Intelligent perception technology:

Context-aware computing technologies, which have begun to evolve in recent years, could fundamentally change the way we interact with devices. The technology uses contextual and contextual information to meet the user's needs and deliver contextual awareness-based content, features, and experiences.

When textile testing instruments integrate these intelligent sensing technologies, the rules will also change. One of the challenges engineers often face is holding the probe in both hands without having time to change the configuration of the instrument. Voice control not only allows you to interact with the instrument hands-free, but it also makes it easier for you to interact with the instrument's features.

In addition, Intelligence** can be used to highlight relevant or valuable data. The oscilloscope can be automatically scaled and configured based on the valuable portion of the signal, and relevant measurements can be added based on the shape of the signal. As technology evolves, mobile-based instruments will be able to integrate and leverage the benefits of contextual intelligence.

2. Cloud Connectivity Technology:A new generation of instruments that integrate network and cloud connectivity can provide engineers with the same benefits. Multiple engineers can access data and user interfaces at the same time, anywhere.

When engineers in different locations collaborate on debugging, they can interact with the instrument in real time to better understand the communication problem, rather than just sharing static screenshots. Cloud technology can dramatically improve the efficiency and productivity of engineering teams.

3. Mobile Technology:

Based on the hardware resources provided by mobile devices, the advantages of new components and new technologies are fully utilized in the design of next-generation instruments. The use of the new generation of instruments will be completely different from that of today's instruments. The application running on the mobile device will be responsible for the data processing and user interface.

By eliminating the need for physical knobs, buttons, and displays, the instrument is left with only a measurement and timing system for hardware, resulting in a smaller size and lower cost. Users also don't need to be limited by tiny built-in displays, small onboard storage, and slow running speeds. Instead, they can use larger, crisper displays, gigabytes of data storage, and multi-core processors.

The built-in camera, microphone, and accelerometer also enable new features such as capturing images of test setups or recording audio annotations to combine with the data. Users can even develop custom apps to meet specific needs.

While traditional textile inspection instruments can also integrate better performing components, they are slower than mobile devices. With economies of scale and fast innovation cycles, consumer electronics instruments and systems that leverage these consumer electronics instrumentation systems to keep advanced technologies low while keeping costs low.

In addition to using human senses to evaluate the quality of silk fabrics during the Spring and Autumn Period and the Warring States Period, China also used the feathers of five-colored pheasants as the color standard for evaluating fabric dyeing. From the Zhou Dynasty, the length and width of fabrics were measured with a ruler, and a standard was formulated. With the development of textile technology, it is required to have special instruments to inspect the products to ensure the stability of product quality.

Since the 20th century, textile enterprises have used manual mechanical instruments to detect semi-finished products and finished products, on the one hand, to inspect the quality, and on the other hand, to control the normalization and standardization of textile production. After the advent of chemical fibers, more testing items and instruments are required to reflect the quality and characteristics of products. With the rapid development of modern electronic technology and computer technology, some modern textile instruments use direct digital display, and some are equipped with microprocessing calculation systems, which directly print out the average and discrete indicators of the test results, which improves the test efficiency and reduces human error.

There are many types of textile testing instruments, including mechanical property testing instruments, appearance quality testing instruments, fabric style testing instruments, physical property testing instruments and process property testing instruments.

With the rapid development of social economy, the production and sales of commodities are no longer limited to one region, but commercial exchanges between countries and continents. The quality indicators of a commodity have also brought about a change.

At present, China's textile industry is facing unprecedented opportunities and challenges, after global economic integration, market competition will be more intense. The focus of competition is the grade, quality, style and cost performance of the product. The means used to improve competitiveness are technological progress and technological innovation.

In the 21st century, with the rapid development of science and technology, textile enterprises must correctly understand themselves, keep pace with the times to improve the grade and quality of textile fabrics, and promote China's transformation from a textile country to a textile power. In order to control the production quality of textile products, manufacturers of textile fabrics must be more strict in the production process.
