Performance Item Common Market Blend This 45S Siro-Compact Yarn Why It Matters
Surface Appearance May turn fuzzy after wear and washing Anti-pilling acrylic helps control the fabric face A cleaner surface improves shelf appeal and supports repeat-order confidence.
Pilling Resistance Often varies by batch and finishing Targets ISO 12945-2 Grade 3-4 performance Better pilling control matters for school socks, casual socks, and high-friction wear.
Hairiness Higher fly and lint can affect fine-gauge feeding Siro-compact spinning helps reduce hairiness Lower hairiness supports cleaner knitting and fewer avoidable machine stops.
Running Stability Can become sensitive during long production runs Nylon and polyester add strength and consistency Stable running helps reduce waste, downtime, and trial adjustments.
Hand Feel May feel dry or overly synthetic Merino wool adds a softer touch The finished sock feels more comfortable without losing practical durability.

Why Buyers Use This Yarn

FAQ: Professional Questions About This Yarn

Q1: Is 45S/1 suitable for 14G-18G sock machines?

Yes. The 45S/1 count is designed for fine-gauge sock knitting, and the siro-compact structure helps the yarn feed more smoothly on 14G-18G machines.

Q2: Can this yarn be plated with spandex or ACY?

Yes. Its compact structure and lower hairiness support more stable plating with spandex or ACY in fine-gauge hosiery production. We recommend testing with your target needle count and tension setting before bulk order confirmation.

Q3: Why use this blend instead of a standard acrylic/polyester sock yarn?

This blend gives you a better balance of surface control, softness, and strength. Anti-pilling acrylic helps keep the sock face cleaner, merino wool improves touch, and nylon/polyester support durability and running stability.

Q4: What pilling and wash-fastness levels do you target?

The yarn targets ISO 12945-2 Grade 3-4 for pilling performance, while dark shades target around Grade 4.0+ under ISO 105-C06 for wash fastness. Final results still depend on knitting structure, color depth, finishing, and testing conditions.

Q5: What information should we send for shade matching or samples?

Please send your Pantone number or physical swatch, target gauge, sock type, expected quantity, and testing requirements. With this information, we can arrange lab dips or sample cones more efficiently.

Q6: Can you adjust the count, composition, or sustainability option?

Yes. We can review custom count, color, and composition requests for suitable programs. A recycled polyester version or responsible wool option can also be discussed at the sampling stage, especially when your customer has sustainability requirements.
