Cashmere sweaters and wool knits tend to live at the top of every wardrobe wish list. They feel impossibly soft, drape beautifully, and somehow make even the simplest outfit look considered. The catch is that these natural fibres demand a little more respect than your everyday cotton tee, and a single careless wash can transform a beloved cardi into something resembling a felted tea cosy.
In Australia, knitwear season hits differently depending on where you live. Brisk Melbourne mornings, foggy Canberra evenings, and even Sydney's sudden winter snaps all create situations where a good wool jumper earns its keep. Australians also sit at a curious crossroads with wool. The country built its wool industry on merino, and the fibre still forms the backbone of local labels and international fashion houses alike.
This walkthrough covers everything worth knowing about keeping knitwear looking pristine, from decoding care labels to banishing moths and reviving a flattened pillow. Whether you are a cashmere devotee or a merino loyalist, the rules below will help your pieces last for years rather than seasons.
Cashmere and wool both come from animals, but the similarities stop at the surface level. Cashmere comes from the soft undercoat of cashmere goats, mostly raised in Mongolia and China. Wool generally refers to fibre shorn from sheep, with merino the gold standard for next-to-skin softness thanks to its fine micron count. A lower micron number means a finer fibre, which usually translates to a less itchy hand-feel against bare skin.
Australian merino carries a particularly strong reputation because local climate and pasture produce fibres with excellent crimp and elasticity. Many local brands source wool directly from Tasmanian or New South Wales stations, and the Australian Wool Innovation mark on a label signals traceability under country-of-origin standards. Checking this mark helps separate genuinely Australian-made knitwear from imported blends marketed as merino-inspired.
Blends complicate things further. A sweater labelled 70 percent wool and 30 percent cashmere behaves differently from a 100 percent cashmere piece, generally holding its shape better. Recycled wool and machine-washable wool treatments have also changed the game, with some modern garments designed to survive a standard cold cycle without felting.
| Property | Cashmere | Merino wool | Standard wool |
|---|---|---|---|
| Source | Cashmere goat undercoat | Merino sheep | Various sheep breeds |
| Typical micron count | 14 to 19 | 18 to 24 | 25 and above |
| Softness | Very soft, luxurious | Soft, gentle on sensitive skin | Can feel coarse or itchy |
| Warmth per gram | Higher | High | Moderate |
| Pilling tendency | Moderate | Low to moderate | Moderate to high |
| Care difficulty | Higher | Moderate | Moderate |
Most knitwear damage happens in the wash, particularly when hot water, agitation, and heat all collide in a moment of distraction. Cold water is always the safest starting point, ideally below 30 degrees Celsius, and a pH-neutral wool detergent works far better than standard laundry liquid. Specialist washes are widely stocked at Australian chemists and chains, so there is no need to hunt down an obscure import.
Hand washing remains the gold standard. Fill a basin with cool water, swirl in a capful of detergent, and submerge the garment for around ten minutes. Press out water gently without wringing, then rinse in fresh cool water until the suds disappear. For machine washing, skip the top loader entirely. Front loaders with a dedicated wool or handwash cycle use far less agitation and protect the fibres.
Hard water, common around Perth and parts of regional South Australia, can leave mineral deposits that make wool feel stiff over time. Adding a small splash of white vinegar to the rinse counteracts this and keeps fibres springy. Whatever method you choose, never twist or wring. Rolling the knit inside a clean dry towel and pressing out moisture is the gentlest approach.
While you are mid-routine, beauty staples like long-wearing matte lipsticks often share a similar philosophy of careful application and slow removal, and the cross-over between makeup prep and garment prep is stronger than it looks.
Drying deserves more attention than it usually gets. Knits should always be dried flat, ideally on a clean towel placed on a rack away from direct sunlight and any heating vents. Hanging wet wool stretches the shoulders and creates those tell-tale pointy peaks that no amount of blocking later fixes. Patience is non-negotiable. Air drying can take 24 to 48 hours depending on thickness.
Reshaping while damp is the secret to professional-looking results. Smooth the garment back to its original dimensions, coaxing the hem and cuffs into alignment, and let gravity do the rest. If a sweater has stretched out of shape, gentle blocking with rust-proof pins on a flat surface can restore the silhouette.
Pilling, those tiny bobbles forming under the arms and along the sides, is a natural consequence of fibre migration. A cashmere comb or fabric shaver removes pills quickly without damaging the knit. Run the comb in one direction across the affected area, and resist pulling pills off by hand, as that pulls fibres loose and accelerates wear.
Moths love keratin, the protein in animal fibres, and an unprotected closet is an open invitation. Cedar blocks, lavender sachets, and commercial moth deterrents all help, though they work best as a barrier rather than a cure for an active infestation. Storing knits in breathable cotton bags or archival boxes beats plastic bins, which trap moisture and invite mildew.
Before packing pieces away for summer, make sure every garment is freshly laundered. Moths are drawn to body oils, food residue, and perspiration far more than clean fibre. Folding rather than hanging prevents shoulder distortion, and acid-free tissue between layers helps creased knits recover their shape.
For those downsizing a wardrobe, donating to charities like Vinnies or the Salvation Army keeps pieces circulating locally while supporting community programs. Many op shops in Melbourne and Sydney have become surprisingly discerning, particularly for natural fibre knitwear.
Even beautiful knitwear occasionally needs mending. Small holes respond well to needle-felting or invisible mending, and many tailors in capital cities now offer specialist cashmere repair services. Pulled threads should be eased back into place with a needle rather than snipped, as trimming creates runs along the rib.
Refreshing flat-smelling knits between washes is straightforward. A quick spritz with fabric refreshener and a few hours on a flat surface in a breezy spot does wonders. Steaming outperforms ironing for wrinkles, since direct heat crushes fibre scales and dulls the surface over time.
