Caring for Cashmere: Why Wash Level Matters for Longevity

Cashmere has long been synonymous with luxury: prized for its softness, warmth, and elegant drape. Yet behind its delicate allure lies a textile that demands mindful care. One of the most overlooked—but essential—factors in ensuring the longevity of cashmere garments is understanding their wash level. In today's knitwear landscape, where terms like “washable cashmere” and “machine washable” are increasingly common, clarity is key. What do these labels really mean, and how should one care for cashmere to preserve its beauty over time?

Wash level refers to the degree to which a garment can withstand washing—particularly in a machine—without compromising its fibre structure, shape, or softness. It is often a result of post-processing techniques or fibre blending that enhance durability while retaining comfort.

In cashmere, wash level may be classified across a range:

• Hand-wash only – Traditional high-purity cashmere that requires the gentlest care.

• Delicate machine-washable – Typically processed or blended fibres designed to survive mild machine cycles.

• Easy-care / fully machine-washable – Engineered for convenience, often at the expense of tactile luxury.

Understanding this spectrum empowers both buyers and designers to make informed choices around garment use and longevity.

Cashmere fibres are extremely fine—often less than 19 microns—and sensitive to temperature, friction, and alkaline detergents. Without appropriate care, they can easily felt, shrink, or lose their supple handfeel.

To enhance washability, manufacturers may:

• Apply enzyme treatments that reduce felting risk.

• Blend with fibres like Merino wool, silk, or synthetics for added structure.

• Use finishing techniques (e.g., tumble washing, steaming) to stabilise the fabric before sale.

However, these interventions can subtly affect the fibre's natural properties. For example, fully washable blends may sacrifice some of the signature softness or breathability of untreated cashmere.

Practical Guidance for Longevity

No matter the stated wash level, best practices remain crucial:

• Always follow the care label. If it suggests hand washing, don’t be tempted by the wool cycle.

• Use gentle detergents. Opt for pH-neutral or cashmere-specific formulas.

• Wash infrequently. Cashmere benefits from minimal washing; airing between wears maintains freshness.

• Dry flat. Avoid hanging or wringing, which can distort shape.

• Store thoughtfully. Fold and store with cedar or lavender to ward off moths.

Bonus Tip for Retail & Brands

Clarity around wash levels is increasingly important in product storytelling. Customers appreciate transparency—especially when investing in high-end fibres. Consider adding:

• A short explanation of the garment’s wash level during sales.

• QR codes linking to garment-specific care videos.

• Wash-level icons to help consumers make quick, informed choices.

A word to the wise: “washable” does not always mean “less luxurious”—but the perception can persist. For high-end knitwear, striking the right balance between wearability and refinement is an art. Some designers intentionally preserve hand-wash-only status as a mark of exclusivity; others embrace innovation in fibre blends to democratise cashmere for daily wear.

Ultimately, understanding the wash level isn't just a technical detail—it's a passport to longer-lasting elegance.
