Cashmere Micron Count Guide: 14.5-19.5μm for B2B Buyers

Cashmere Fiber Fineness: A Practical Micron Guide for B2B Buyers (14.5-19.5μm)

When sourcing cashmere, the micron count is arguably the most critical specification—it determines softness, price, and end-use suitability. Yet many buyers struggle to interpret fineness data, especially when comparing suppliers across regions. This guide provides a comprehensive, practical breakdown of cashmere micron ranges, grading standards, and quality control considerations, empowering you to make informed sourcing decisions.

What Is Cashmere Micron Count?

Micron (μm) measures fiber diameter. The lower the micron, the finer and softer the cashmere. Cashmere fibers range from about 14.5 to 19.5 microns, with anything below 15.5 considered ultra-fine and highly premium. For context, human hair is roughly 70-100 microns, so cashmere is exceptionally fine.

Fineness directly impacts:

• Softness – finer fibers feel silkier against the skin.
• Durability – finer fibers can be more delicate, requiring careful spinning.
• Price – finer cashmere commands higher prices due to lower yields and higher processing costs.
• End-use – ultra-fine cashmere is ideal for luxury knitwear, while coarser grades suit heavier outerwear.

Cashmere Micron Grading: The Industry Standard

While there is no universal grading system, most mills and suppliers categorize cashmere into three tiers:

Grade	Micron Range	Typical Use	Relative Price Index
Ultra-fine	≤ 15.5 μm	Luxury scarves, lightweight knitwear, baby garments	High (100-120)
Fine	15.6-16.5 μm	Premium sweaters, cardigans, accessories	Medium-High (90-100)
Standard	16.6-18.5 μm	Everyday knitwear, blended yarns	Medium (75-90)
Coarse	18.6-19.5 μm	Outerwear, blankets, upholstery	Lower (60-75)

Note: Some suppliers may label 16-17 μm as “premium”—always verify the exact micron range in your specification sheet.

Why 14.5-19.5 μm Matters for B2B Buyers

As a B2B buyer, you need to match micron to your product line and price point. For example:

• If you sell luxury women’s knitwear retailing above $300, you’ll want 15-16 μm cashmere.
• For men’s sweaters in the mid-range, 16-17 μm is standard.
• For cost-effective blends, 18-19 μm works well, especially when combined with silk or wool.

Understanding the micron range helps you negotiate pricing, set quality expectations, and avoid overpaying for unnecessary fineness.

How Micron Count Is Measured

The most reliable method is laser-based optical fiber diameter analysis (OFDA) or scanning electron microscopy (SEM). These methods provide accurate average micron and standard deviation. Some suppliers may use projection microscopy, which is less precise. Always request the testing method and a certificate of analysis (COA) from your supplier.

Key metrics to request:

• Average micron (μm)
• Standard deviation (SD) – lower SD means more uniform fibers
• Coefficient of variation (CV%) – typically below 22% is good
• Fiber length (mm) – longer fibers (34-40 mm) are better for spinning

Regional Variations in Cashmere Fineness

Cashmere goats are raised in several regions, each with distinct fiber characteristics:

• Inner Mongolia, China – the world’s largest cashmere producer. The Ordos region, where our factory is based, is renowned for consistently fine fibers averaging 15-16 μm. The harsh climate and high altitude (1,000-1,500m) contribute to a fine undercoat.
• Mongolia – similar quality to Inner Mongolia, with some variation depending on herding practices.
• Afghanistan/Iran – often coarser, averaging 17-19 μm, but with good availability.
• Australia/New Zealand – limited production, but fine fibers due to selective breeding.

As a source factory in Ordos, Inner Mongolia, we have direct access to the finest raw cashmere in the world, with an average micron of 15.5 μm for our premium line.

Quality Control: What to Look For in a Supplier

Beyond micron count, quality control (QC) ensures consistency. A reliable supplier should:

1. Provide COAs for every batch, including micron, length, and contamination levels.
2. Conduct third-party testing – such as SGS or Intertek – upon request.
3. Adhere to international standards – ISO9001 for quality management, OEKO-TEX for chemical safety, and GOTS if you require organic certification.
4. Maintain traceability – from herder to finished product.

Common Quality Defects to Watch For

• Coarse hair contamination – guard hairs that aren’t fully removed.
• High vegetable matter – plant debris that affects spinning.
• Inconsistent micron – high SD indicates poor sorting.
• Short fibers – below 30 mm reduces yarn strength.

At DONGXIAO Cashmere, we implement rigorous QC at every stage: raw material sorting, dehairing, dyeing, and spinning. Our state-of-the-art testing lab ensures each batch meets your exact micron specification.

Sourcing Strategies: How to Use Micron Data in Negotiations

When comparing supplier quotes, don’t just look at price per kg. Evaluate the cost per garment based on micron and yield. Finer cashmere may cost more per kg but could require less material for the same warmth-to-weight ratio.

Negotiation tips:

• Request a sample card with swatches of different micron grades.
• Ask for a trial batch with your required micron and test it in your own lab.
• Inquire about blending options – adding 10-20% silk can enhance luster without increasing micron.
• Discuss MOQ flexibility – our factory offers MOQs starting from 200 kg for raw material, 500 kg for yarn, and 500 pieces per design for garments.

Case Study: Selecting Micron for a Luxury Knitwear Line

A European brand approached us to develop a premium knitwear line. They wanted a soft, lightweight feel but had a target retail price of $250. We recommended a 15.8 μm cashmere with a 34 mm fiber length. This allowed a 12-gauge knit that was both fine and durable. We provided a COA showing a CV of 18%, ensuring evenness. The line launched successfully, with customer satisfaction rates above 95%.

Frequently Asked Questions

Q: Is lower micron always better? A: Not necessarily. Ultra-fine fibers (14.5-15 μm) can pill more easily and are more expensive. Match micron to your product’s intended use and price point.

Q: How does micron affect pilling? A: Finer fibers are more prone to pilling because they break and tangle. However, proper spinning and finishing (e.g., anti-pilling treatment) can mitigate this.

Q: Can you provide custom micron blends? A: Yes, we can blend different micron lots to achieve a target average, but this may affect uniformity. We recommend using single-lot for premium products.
