Why Fine Merino Matters

Fine merino has become one of the most respected fibres in contemporary knitwear, not because of marketing romance, but because of measurable, technical qualities that genuinely affect comfort, performance and longevity. At CH Cashmere, we work with merino yarns from Xinao, one of the industry’s most reputable spinners, whose finest counts reach 120 nm / 130s, a level associated with premium softness and refined drape.

Understanding why this matters helps customers make informed, confident choices.

What “Fine Merino” Actually Means

Merino wool is graded by fibre diameter, measured in microns. The finer the fibre, the softer it feels against the skin because thin fibres bend more easily and do not prick nerve endings. This relationship is well‑established across textile science: lower micron = softer feel.

The industry also uses the Super S scale (e.g., 100s, 120s, 130s) to indicate fineness. A higher number corresponds to a finer average fibre diameter. For example, Super 120s typically sits around 17.5 µm, and Super 130s around 17.25 µm, offering a noticeable upgrade in softness and drape compared with lower grades.

Xinao’s 120 nm / 130s merino sits in this refined category, soft enough for next‑to‑skin comfort, yet still robust enough for regular wear.

Why Fineness Matters in Real Life

1. Comfort Without Irritation

Fine merino fibres flex easily, avoiding the prickling sensation associated with coarser wool. Superfine grades (16.5–18.5 µm) are widely recognised as suitable for direct skin contact, offering smoothness even for sensitive wearers.

Xinao’s 120 nm / 130s yarn falls within this comfort‑focused range, making it ideal for luxury knitwear that feels gentle and breathable.

2. A More Refined Drape

Finer fibres create yarns that fall more fluidly, producing garments with a clean, elegant silhouette. This is a hallmark of 130s merino: a polished drape without stiffness.

For designers, this means knitwear that looks elevated without relying on heavy finishing or synthetic blends.

3. Natural Temperature Regulation

Merino wool is inherently clever: its crimp traps air for insulation, and its hygroscopic core absorbs moisture vapour, helping regulate body temperature across seasons.

Finer merino enhances this responsiveness, creating fabrics that breathe well, wick moisture efficiently, and remain comfortable from cool mornings to warm interiors.

4. Durability — With Honest Trade‑offs

Finer fibres are luxurious, but they are also more delicate. Ultra‑fine grades (e.g., 150s and above) can be prone to abrasion and pilling.

This is why 130s merino is often considered the “sweet spot”:

• softer than 100s or 110s

• more durable than ultra‑fine 150s or 180s

• refined without being fragile

Xinao’s 120 nm / 130s yarn sits precisely in this balanced zone.

Is Finer Always Better?

Not necessarily. Fibre fineness is only one part of the quality equation. As textile research consistently notes, spinning quality, knitting technique, finishing, and garment construction all influence performance as much as the fibre itself.

A poorly spun 130s yarn can underperform a well‑made 100s yarn. Fineness enhances quality, it does not guarantee it.

This is why CH Cashmere works with mills like Xinao, whose consistency, certification and spinning standards ensure that the fineness translates into real world performance.

Why CH Cashmere Chooses Xinao’s Fine Merino

Xinao’s merino yarns offer:

• Reliable fibre grading backed by industry standards

• Stable spinning quality suitable for both machine knitting and hand‑linked finishing

• Balanced fineness (120 nm / 130s) that delivers luxury without compromising durability

• Versatility across sweaters, cardigans, and lightweight layering pieces

For customers, this means knitwear that feels indulgent, performs well, and lasts when cared for properly.

Fine merino matters because it directly shapes how knitwear feels, behaves and endures. Xinao’s 120 nm / 130s merino sits at an ideal intersection of softness, drape and practicality, refined enough for luxury, robust enough for everyday wear.

For CH Cashmere, it’s the fibre that allows us to create knitwear that is genuinely comfortable, technically sound, and beautifully made.
