Mx type metallic yarn manufacturers

Mx Type Metallic Yarn is a composite yarn made by twisting metallic film (usually PET) with supporting yarns like Nylon, Rayon, or Polyester. When sourcing, you must verify the film thickness (typically 12μm to 25μm) and the width (1/64", 1/100", or 1/127"). The twist density (TPM - Twists Per Meter) is critical as it determines the yarn's strength and the final fabric's hand-feel. Ensure the supporting yarn is of high-tenacity grade to prevent breakage during high-speed weaving or knitting.

For high-end textile production, the yarn must undergo high-temperature dyeing without losing its luster. Request test reports for colorfastness to washing (Grade 4-5) and perspiration resistance. If the yarn will be used for swimwear or denim, specify the need for acid and alkali resistance to prevent the metallic coating from peeling or oxidizing. Ensure the supplier uses eco-friendly dyestuffs that comply with OEKO-TEX® Standard 100.

Mx Type yarn is widely used in embroidery, sweaters, hosiery, and high-fashion fabrics. For circular knitting, the yarn must have excellent smoothness and low friction to avoid needle damage. For warp knitting or weaving, focus on tensile strength. If the end product is intimate apparel, prioritize soft-touch finishes to ensure the metallic component does not cause skin irritation.

Buyers should prioritize suppliers who can provide REACH and RoHS certifications, ensuring the absence of heavy metals like lead or cadmium in the metallic coating. For the North American market, compliance with CPSIA is necessary if the yarn is used in children's clothing. Additionally, verify the Global Recycled Standard (GRS) if your brand focuses on sustainable sourcing, as recycled PET metallic films are becoming a market standard.

Metallic yarns are sensitive to humidity and salt air, which can cause oxidation (blackening). Insist that the supplier uses vacuum packaging or moisture-proof PE bags with desiccant inside the cartons. For sea freight, ensure the goods are stored in a cool, dry area of the container away from heat sources. On Made-in-China.com, you can utilize STS (Secured Trading Service) to ensure payment is only released after quality verification.

The price of Mx Type yarn is heavily influenced by the current cost of PET film and supporting fibers (Nylon/Polyester). Negotiate based on volume tiers; typically, orders exceeding 500kg can secure a 5-10% discount. For custom colors, ask for a lab-dip first. To reduce costs, consider sourcing standard stock colors which usually have a lower MOQ (as low as 1-5kg) compared to custom-dyed lots which may require 50kg+.

Look for Audited Suppliers who have undergone on-site inspections by third-party agencies like SGS or Bureau Veritas. Check their Business Type (Manufacturer vs. Trading Company) and prioritize those with at least 5 years of export experience. Review their Transaction History and response rate; a professional supplier should provide a technical data sheet (TDS) and a proforma invoice that clearly outlines the weight, composition, and lead time.

Request a pre-shipment inspection (PSI) focusing on net weight verification (excluding the weight of the paper cone) and color matching under standard light sources (D65/TL84). Perform a breakage test to ensure the metallic film is properly wrapped around the core yarn. Ensure the batch numbers are consistent to avoid color shading (long-tail defects) in the final textile production.
