Domestic laundry technology decided which fabrics won

Washing was heavy manual work and it shaped everything

Before mechanisation, laundering meant carrying and heating water, soaking, rubbing garments against a board or beating them, boiling whites, rinsing repeatedly, wringing by hand or through a mangle, and drying without any reliable means of doing so indoors. It occupied a substantial part of a week and it was physically hard.

That cost shaped the wardrobe directly. Outer garments in wool were not washed at all, but brushed, aired and spot-cleaned, and only the layers next to the skin went into the water. The linen shirt and shift existed partly as a washable barrier between the body and clothing that could not be laundered.

It also explains the long dominance of linen and cotton for those layers. Both tolerate boiling, both survive hard mechanical treatment, and both can be bleached, which mattered enormously when the visible sign of cleanliness was whiteness.

Mechanisation changed the volume, then the fabric

The powered washing machine removed the physical labour and, more importantly, made frequent washing practical. Once a garment could be laundered often without a day’s work, garments began to be worn closer to the body more freely, and the elaborate system of washable underlayers protecting unwashable outer ones started to unwind.

Frequency rose steadily as machines spread, and rising frequency put a different demand on cloth. A garment washed weekly needs to survive far more cycles than one washed twice a year, and colours need to be fast to repeated laundering rather than merely to light.

The drum machine that tumbles rather than agitates changed the mechanical profile again, and the domestic tumble dryer changed it more, since heat and tumbling together are considerably harder on cloth than line drying.

Easy care was a selling point before it was a property

From the middle of the twentieth century the decisive commercial argument for a fabric was frequently how it behaved in the wash. Resistance to creasing, dimensional stability, quick drying and not needing an iron were promoted heavily, and they were promoted because they addressed the largest remaining chunk of domestic labour.

Synthetic fibres were extremely well suited to that argument. Being thermoplastic they can be heat-set, so they hold their shape and their pleats; being hydrophobic they absorb little water, so they dry fast; and they do not shrink or felt in the way natural fibres do.

Resin finishes applied to cotton did the same job for a natural fibre, cross-linking the cellulose so it could not crease as readily. They worked, and they came with real trade-offs in strength and hand, which is a pattern that recurs whenever a property is added to a fibre rather than being native to it.

The trade-offs arrived later

Wardrobes made of easy-care fabric are genuinely less work, and the costs became apparent over time. Synthetics hold body oils in a way that cotton does not, which is why odour became a laundry problem it had not previously been. They shed microfibres in every wash. And they feel different against skin in warm weather, which is not a small matter.

Domestic drying at high heat has its own consequences, since heat degrades elastane, sets stains and creases, and shortens the life of nearly everything. A great deal of the wear people attribute to washing is actually drying.

There has been a partial swing back, most visibly in cold washing and in a renewed preference for natural fibres in some categories. Cold washing saves energy and is gentler on fibre and colour, and it is noticeably worse at removing oily soil, which is the trade being made whether or not anyone names it.

Reading a wardrobe as a record of its laundry

It is a useful exercise to look at a wardrobe and ask what laundering regime it assumes. A wardrobe of heavy cotton and wool assumes infrequent washing, air drying, and pressing. A wardrobe of blends and knits assumes a machine, warm water and a dryer, and it will not survive being treated as though it were the other one.

The historical pattern is consistent enough to be worth stating plainly: whenever laundering became easier, clothing became something people owned more of and washed more often, and cloth was reformulated to survive the new regime.

Which suggests that the current direction of travel matters. Washing cooler and less often, drying without heat, and repairing rather than replacing all push back towards fibres and constructions that tolerate that treatment, and away from ones designed for a machine to handle them roughly. Whether wardrobes follow is a different question, and an open one.
