How to Care for Cotton, Linen and Lyocell Knits

Caring for cotton, linen and lyocell knits comes down to three rules that repeat on every RUIJIN product page: cold water, gentle motion, dry flat in the shade. Hand-wash the delicate blends, machine-wash the everyday ones on a gentle cycle, never wring, and never hang a wet knit — hangers stretch shoulders, hot water shrinks fibres, and tropical sun fades colour in a single afternoon. Do those three things and a $30–50 knit top survives years of twice-weekly rotation instead of one humid season. Here is exactly how, with the real care lines from the current collection and what to do when wrinkles, pilling or stretching show up anyway.

How often should you wash knits in a tropical climate?

Less often than the humidity makes you feel like you should — and more often than a temperate-zone guide suggests. The honest rhythm for Singapore and Malaysia:

• Knit tops: every 2–3 wears. Knits do not trap odour the way synthetics do, and every wash cycle costs them a little elasticity. Air the piece flat overnight between wears — most "day-two" smell in the tropics comes from trapped humidity, not soil, and an hour in a fan's airflow resets it.
• Shirts and wovens: after every wear. The ramie and linen shirts sit against skin directly and crease with wear, so they go in the wash each time.
• Sweat days: immediately. One brutally humid commute changes the math — salt and moisture weaken fibres if they sit, so a day that soaked through the fabric is a wash-day, no matter how recently it was worn.

The reason the frequent-wash question matters at all: a small capsule wardrobe (three or four tops in rotation) means each piece gets washed twice a week. Care method, not frequency, decides whether that rotation costs your knits a season or a decade.

What do the care notes on RUIJIN pages actually say?

Read four or five product pages and a pattern appears — the care lines are not boilerplate, they are two real tiers matched to fabric construction:

• Delicate blends → hand wash. The Matte-Texture Short-Sleeve Knit Top (45% cotton, 29% rayon, 26% washi paper yarn) says: "hand wash cold, dry flat in the shade, cool iron." The same instruction appears on the wool-blend crewneck tee and the Lyocell-acetate Soft-Hand Knit Top.
• Everyday knits → machine wash cold, gentle. The Seamless-Knit Short-Sleeve Top (46.7% Lyocell) says: "machine wash cold on gentle cycle; lay flat to dry." The minimal crew-neck cardigan repeats it: "machine wash cold gentle, dry flat in the shade."

So the decision is already made for you, per piece, on its product page — hand wash where the fibre blend (silk, wool, paper yarn) demands it, machine gentle where it doesn't. The Button-Front Crew-Neck Knit Cardigan, which pairs a washi-and-nano-silk panel with a linen panel, carries the delicate tier: "hand wash cold, dry flat in the shade." When in doubt, the page is the label.

What is the right way to hand wash a knit top?

Five minutes, one basin, no scrubbing:

1. Fill a basin with cold water and a capful of mild detergent (wool or delicate wash is ideal; regular detergent works if fully dissolved).
2. Submerge the knit and press it gently for a minute — let the water move through the fabric instead of rubbing the fabric against itself.
3. Soak 5–10 minutes. Longer soaks are fine for cotton and linen; keep lyocell and silk-blend knits to the short end.
4. Rinse in cold water until it runs clear, then press the water out with your palms — never twist or wring. Wringing is what twists a shoulder seam out of shape.
5. Lay the knit on a dry towel, roll the towel up with the knit inside, and press to blot. The towel takes most of the water out in thirty seconds.

That is the entire technique. There is no benefit to hot water, longer soaking, or more agitation — those three only cost you fit and colour.

Should you dry knits flat or hang them?

Flat, in the shade — every care line in the collection repeats it, and here is why each half matters:

• Flat, not hanging. A wet knit can weigh two or three times its dry weight. On a hanger, that weight pulls straight down through the shoulders — the classic stretched-loop marks that no wash can reverse. Flat on a drying rack or towel, the weight is supported by the surface underneath.
• Shade, not sun. Direct tropical sun bleaches colour and degrades elastic fibres fast — a knit dried on a balcony rail in full Singapore sun fades measurably in weeks. Indoors, near a fan or in moving air, most knits are dry in a few hours anyway; the humidity slows drying less than you'd expect once the towel blot has removed the bulk of the water.

Woven pieces are the exception: the ramie and linen shirts can hang on a proper hanger to dry — they carry weight on their woven structure, not on knit loops, and hanging them actually helps the wrinkles fall out.

Can you machine wash lyocell and cotton knits?

Yes — when the product page says so. The pattern from the care lines: everyday cotton, cotton-polyester and Lyocell knits carry machine-wash instructions, and they mean it. Three settings do all the work:

• Cold water only. Hot water is what shrinks cotton knits and dulls Lyocell's drape.
• Gentle cycle. Same reasoning as hand washing — let water move through the fabric, don't pummel it.
• Mesh laundry bag. Zips, hooks and drum friction cause most pilling; a $3 mesh bag removes all three.

Then out of the machine and straight to flat drying — a knit left balled up wet in the drum dries creased and mis-shaped. Skip the tumble dryer entirely: it is the single fastest way to shrink a cotton knit and rough up a Lyocell surface.

How do you deal with wrinkles, pilling and stretching?

Three fixes, all reversible if caught early:

• Wrinkles: steam beats ironing for knits — hang the piece in the bathroom during a hot shower, or use a steamer on low. If you iron, the care lines say cool iron, and a pressing cloth between iron and knit is cheap insurance. Linen shirts, on the other hand, take a warmer iron slightly damp and look better for it.
• Pilling: those tiny fuzz balls come from friction — bags, seatbelts, washing machine drums. A sweater comb or fabric shaver used flat and gently removes them in two minutes; do it before washing, not after.
• Stretching: shoulder loops stretched by a hanger or a wet hang won't shrink back — but a whole knit that relaxed a size can be coaxed back: wet it again in cold water, blot in a towel, and reshape it flat by hand to its original measurements while damp, then dry flat in the shade.

How should you store knits between wears and seasons?

Fold, never hang. On a shelf, a knit keeps its shoulder line indefinitely; on a hanger, gravity reworks it month by month. Three folds max per stack — the weight of a tall pile presses creases into the bottom pieces.

Between seasons, knits go into a breathable cotton storage bag with the fold lines varied from their usual folds. Skip vacuum sealing for linen and lyocell — the compression sets hard creases that take months to relax; a folded knit in a drawer or breathable bag needs nothing more. The wool-blend pieces (like the contrast-trim crewneck) deserve a cedar block or lavender sachet nearby — the only fibre in the collection that moths actually want.

None of this is precious — it is three habits: cold and gentle when washing, flat and shaded when drying, folded and shelved when storing. Build the wardrobe around fabrics that reward those habits, and the RUIJIN collection page is organised by exactly them — every cotton, linen and Lyocell knit top lists its care line in full.
