Life cycle

Clothing maintenanceedit

Clothing suffers assault both from within and without. The human body sheds skin cells and body oils, and exudes sweat, urine, and feces. From the outside, sun damage, moisture, abrasion, and dirt assault garments. Fleas and lice can hide in seams. Worn clothing, if not cleaned and refurbished, itches, becomes outworn, and loses its aesthetics and functionality (as when buttons fall off, seams come undone, fabrics thin or tear, and zippers fail).

Often, people wear an item of clothing until it falls apart. Some materials present problems. Cleaning leather is difficult, and bark cloth (tapa) cannot be washed without dissolving it. Owners may patch tears and rips, and brush off surface dirt, but materials like these inevitably age.

However, most clothing consists of cloth, and most cloth can be laundered and mended (patching, darning, but compare felt).

Laundry, ironing, storageedit

Humans have developed many specialized methods for laundering, ranging from early methods of pounding clothes against rocks in running streams, to the latest in electronic washing machines and dry cleaning (dissolving dirt in solvents other than water). Hot water washing (boiling), chemical cleaning and ironing are all traditional methods of sterilizing fabrics for hygiene purposes.

Many kinds of clothing are designed to be ironed before they are worn to remove wrinkles. Most modern formal and semi-formal clothing is in this category (for example, dress shirts and suits). Ironed clothes are believed to look clean, fresh, and neat. Much contemporary casual clothing is made of knit materials that do not readily wrinkle, and do not require ironing. Some clothing is permanent press, having been treated with a coating (such as polytetrafluoroethylene) that suppresses wrinkles and creates a smooth appearance without ironing. Excess lint or debris may end up on the clothing in between launderings. In such cases, a lint remover may be useful.

Once clothes have been laundered and possibly ironed, they are usually hung on clothes hangers or folded, to keep them fresh until they are worn. Clothes are folded to allow them to be stored compactly, to prevent creasing, to preserve creases or to present them in a more pleasing manner, for instance when they are put on sale in stores.

Certain types of insects and larvae feed on clothing and textiles, such as the black carpet beetle and clothing moths. To deter such pests, clothes may be stored in cedar-lined closets or chests, or placed in drawers or containers with materials having pest repellent properties, such as lavender or mothballs. Airtight containers (such as sealed, heavy-duty plastic bags) may also deter insect pest damage to clothing materials.

Non-ironedit

A resin used for making non-wrinkle shirts releases formaldehyde, which could cause contact dermatitis for some people; no disclosure requirements exist, and in 2008 the U.S. Government Accountability Office tested formaldehyde in clothing and found that generally the highest levels were in non-wrinkle shirts and pants. In 1999, a study of the effect of washing on the formaldehyde levels found that after 6 months after washing, 7 of 27 shirts had levels in excess of 75 ppm, which is a safe limit for direct skin exposure.

Mendingedit

When the raw material – cloth – was worth more than labor, it made sense to expend labor in saving it. In past times, mending was an art. A meticulous tailor or seamstress could mend rips with thread raveled from hems and seam edges so skillfully that the tear was practically invisible. Today clothing is considered a consumable item. Mass-manufactured clothing is less expensive than the labor required to repair it. Many people buy a new piece of clothing rather than spend time mending. The thrifty still replace zippers and buttons and sew up ripped hems.

Recyclingedit

Used, unwearable clothing can be repurposed for quilts, rags, rugs, bandages, and many other household uses. Neutral colored or undyed cellulose fibers can be recycled into paper. In Western societies, used clothing is often thrown out or donated to charity (such as through a clothing bin). It is also sold to consignment shops, dress agencies, flea markets, and in online auctions. Used clothing is also often collected on an industrial scale to be sorted and shipped for re-use in poorer countries. Globally, used clothes are worth $4 billion with the US as the leading exporter at $575 million.

Synthetics, which come primarily from petrochemicals, are not renewable or biodegradable.

Excess inventory of clothing is sometimes destroyed to preserve brand value.
