Why do garment factories use needle detectors?

Why use a needle detector, because in the 1970s, there were incidents of child injury caused by broken needles in children's clothing. In order to protect the interests of consumers and the safety of consumers' lives, Japan promulgated the Japanese clothing standard testing method. The testing method stipulates that any imported and exported clothing must be tested by testing equipment, and no broken needles or small iron filings should remain in the clothing. Otherwise, a financial penalty of $10,000 to $30,000 is imposed. In view of this, Japan first produced a needle detector with the island as its brand. In the 1980s, the United States and Taiwan followed suit and promulgated the clothing import and export inspection law. In the 1990s, due to the introduction of a large number of foreign trade products, South Korea and China also purchased needle detectors one after another in accordance with international practice, and began to develop the production of needle detectors. At the same time, it also began to explore from theoretical and practical perspectives on the nature, scope of application, various technical indicators, operating procedures, maintenance, maintenance and upgrades, troubleshooting of needle detectors, and maintenance of needle detectors. Specifically, it can be seen from the following contents: 1. The definition and nature of the needle detector are discussed and stipulated; 2. The scope of application and industry of the needle detector is specified; (1) The industry that is likely to cause harm to human life safety; (2) Products that are likely to cause harm to human life safety; (3) Clothing, shoes and hats, handbags, woven products, handicrafts, medicines, food and other products exported to foreign countries. 3. Various technical indicators of the needle detector: (1) the height and width of the needle detector; (2) the testing standards corresponding to the height and width of the needle detector; (3) the technical requirements for conveying and carrying the needle detector ; (4) Various technical indicators of electronic components; (5) Specifications and technical indicators of computer chips and computer programs; (6) Verification of the magnetic field induction range and strength; (7) The signal detection process of the needle detector Data processing; (8) The resistance of the needle detector to external interference is constant; (9) The principle circle of the needle detector body is constant; (10) The preset and elimination of the needle detector fault; (11) The needle detector Handling of conventional performance and special performance; (12) Characteristics and differences of common type needle detectors, computer type needle detectors, and anti-interference needle detectors; (13) Confirmation of needle detector specifications and models; (14) Needle detectors (15) Confirmation of cost-effectiveness of needle detectors; 4.
