Textile needle inspection machine (metal detector) has a wide range of applications in industries such as textiles, clothing, shoes, hats, toys, etc. It is mainly used to detect foreign objects such as broken needles and metal debris in products, ensuring that the products meet safety standards (especially strict market requirements for exports to Japan, Europe, and America). The following are its specific application scenarios and precautions:
1. Clothing manufacturing industry
Application scenarios
Ready to wear inspection:
During the sewing process, the sewing needle may break and remain inside the clothing (such as jeans, shirts, underwear, etc.), and the needle inspection machine can ensure that the finished product has no metal residue.
Clothing exported to Japan and Europe must undergo needle inspection, otherwise it may be returned or fined.
Auxiliary material inspection:
Check whether zippers, buttons, metal decorations, etc. contain sharp metal burrs.
Precautions
High sensitivity models (such as detecting Φ 0.8mm metal) are suitable for lightweight fabrics (such as silk and chiffon).
Final needle inspection is required before packaging to avoid metal contamination (such as mixing of packing nails and staples).
2. Home textile industry
Application scenarios
Bedding/towel inspection:
Check whether there are any sewing needles or metal shavings left on the bed sheets, duvet covers, towels, etc. (especially those that are prone to breakage during the stitching process).
Filling material safety:
Detect metal impurities (such as springs and steel wool) in down comforters and pillows.
Precautions
Thick products (such as blankets) require the use of a flat needle inspection machine or multiple flip inspections.
3. Shoes, hats, and bags
Application scenarios
Shoe production:
Detect shoe soles (possibly mixed with metal nails) and upper decorations (such as rivets and metal buckles).
Luggage/Backpack:
Check for metal defects in zipper heads and frame strips.
Precautions
Products with metal accessories need to adjust sensitivity to avoid false alarms (such as marking exemption areas for allowed metal parts).
4. Toys and maternal and child products
Application scenarios
Plush toys:
The interrupted needle during the sewing process may be hidden in the filling cotton and requires 100% needle inspection (in accordance with EN71-1 and ASTM F963 standards).
Baby Care:
Such as baby bibs, cloth books, etc., to prevent metal foreign objects from scratching children.
Precautions
Toys exported to the European and American markets must provide a qualified needle inspection report.
5. Industrial textiles
Application scenarios
Filter material/non-woven fabric:
Detect metal particles mixed in during the production process (such as equipment wear debris).
Medical textiles:
Surgical gowns, masks, etc. must be ensured to be free of metal contamination (to avoid affecting sterilization or MRI environments).
Precautions
In industrial scenarios, it is necessary to choose anti-interference models (such as when there are motors or frequency converters nearby).
6. Special applications
Recycled fiber products:
Recycled fabrics may contain metal fragments (such as zipper and button residue), and strict needle inspection is required.
Food grade packaging:
Detect metal impurities in textile packaging bags (such as tea bags, coffee filter cloth).
