The 350A1450 Circular Knitting Needle is a high-performance knitting tool designed for circular knitting machines, produced by YANTAI XINYANG through 12 precision manufacturing processes (including forging, quenching, grinding, and polishing).

|---|---|
Made from heat-treated high-carbon steel (SKS51 grade), it delivers exceptional sharpness and wear resistance, ideal for weaving medium-weight fabrics (e.g., cotton T-shirts, polyester underwear, modal loungewear). Its standardized dimensions ensure compatibility with 30”–40” circular knitting machines (e.g., Mayer & Cie OVJA series, Terrot CSM series), a common size in global textile factories.
Specification | Details |
Model | 350A1450 |
Length | 145mm (matched to model number, ±0.1mm tolerance) |
Needle Diameter | 2.5mm (shaft diameter; needle tip diameter 0.8mm) |
Tip Type | Polished sharp point (surface roughness Ra≤0.8μm) |
Material | High-carbon steel (SKS51 grade, HRC 58–60 after quenching) |
Applicable Yarns | Cotton, polyester, spandex blends (yarn fineness 20s–40s) |
Service Life | 3–4 months under 8-hour daily operation (for cotton yarns) |
High Hardness: HRC 58–60 hardness resists wear from abrasive yarns (e.g., cotton-polyester blends), reducing needle replacement frequency by 50% compared to ordinary steel needles (HRC 50–52).
Smooth Tip: Polished surface (Ra≤0.8μm) prevents yarn snagging—especially critical for fine spandex yarns (40D–70D), minimizing fabric defects like loose threads and broken loops.
Uniform Dimensions: The ±0.1mm length tolerance and consistent shaft diameter ensure consistent stitch size (±0.05mm), critical for mass-produced fabrics requiring standardized quality (e.g., T-shirt fabrics with 180g/m² weight uniformity).
Scenario Solution: For textile mills producing 10,000+ pieces of T-shirt fabric monthly, the 350A1450 needle solves the problem of uneven stitches caused by low-quality needles. A Jiangsu-based textile mill specializing in cotton T-shirt fabric reported that after switching to this needle, fabric consistency improved by 90%, and waste rates dropped from 8% to 1.8—saving approximately 2 tons of raw cotton and 20,000 yuan in material costs monthly.
Q1: Can this needle be used for elastic yarns (e.g., spandex)?
A1: Yes, its smooth tip (Ra≤0.8μm) and high strength (tensile strength 1,800 MPa) avoid yarn breakage, making it suitable for elastic blends (up to 30% spandex content). We recommend pairing it with our anti-friction needle oil for extended service life.
Q2: How often should the 350A1450 needle be replaced?
A2: Under normal use (8-hour shifts, 5 days/week) with cotton or polyester yarns, replace after 3–4 months. For abrasive yarns (e.g., cotton-linen blends), replace every 2–2.5 months to maintain stitch quality.
Q3: How to clean the needle to remove yarn residues?
A3: Use a soft-bristle brush (provided in our maintenance kit) to wipe the needle surface, then soak in a neutral cleaning solution (pH 6–8) for 10 minutes—avoid using acidic/alkaline cleaners that damage the needle’s surface finish.
Sample Order: Minimum 10-piece sample orders for testing on your circular knitting machine, with free shipping for orders over 50 pieces. We also provide a test report (including hardness, surface roughness, and dimensional data) for samples.
Customization: Adjust length (120mm–160mm) or tip shape (blunt tip for thick woolen fabrics, sharp tip for fine modal fabrics) based on specialized fabric needs—minimum order quantity 500 pieces for customization.
Maintenance Guide: Free digital guide (PDF format, English/Chinese) on needle cleaning, storage, and replacement, including a troubleshooting section for common issues (e.g., needle bending, tip wear).
