Ironing a shirt

Ironing is the use of an iron, usually heated, to remove wrinkles and unwanted creases from fabric. [1] The heating is commonly done to a temperature of 180–220 °Celsius (356-428 Fahrenheit), depending on the fabric. [2] Ironing works by loosening the bonds between the long-chain polymer molecules in the fibres of the material. While the molecules are hot, the fibres are straightened by the weight of the iron, and they hold their new shape as they cool. Some fabrics, such as cotton, require the addition of water to loosen the intermolecular bonds. Many modern fabrics (developed in or after the mid-twentieth century) are advertised as needing little or no ironing. Permanent press clothing was developed to reduce the ironing necessary by combining wrinkle-resistant polyester with cotton. [3]

The first known use of heated metal to "iron" clothes is known to have occurred in China. [4] The electric iron was invented in 1882, by Henry Seely White. Seely patented his "electric flatiron" on June 6, 1882 (U.S. Patent no. 259,054). [5]

Equipment

Iron

The iron is the small appliance used to remove wrinkles from fabric. It is also known as a clothes iron, steam iron, flat iron, smoothing iron or iron box.

On 15 February 1858 W. Vandenburg and J. Harvey patented an ironing table that facilitated pressing sleeves and pant legs. [6] A truly portable folding ironing board was first patented in Canada in 1875 by John B. Porter. The invention also included a removable press board used for sleeves. [7] In 1892 Sarah Boone obtained a patent in the United States for improvements to the ironing board, allowing for better quality ironing for shirt sleeves. [8]

Tailor's ham

A tailor's ham or dressmakers ham is a tightly stuffed pillow in the shape of a ham used as a mold when pressing curves such as sleeves or collars. [9]

Commercial equipment

Commercial dry cleaning and full-service laundry providers usually use a large appliance called a steam press to do most of the work of ironing clothes. Alternatively, a rotary iron may be used.

Historically, larger tailors' shops included a tailor's stove, used to quickly and efficiently heat multiple irons. In many developing countries a cluster of solid irons, heated alternatively from a single heating source, are used for pressing clothes at small commercial outlets.

Automation

Different machines promise to automate ironing, such as Effie and Panasonic Sustainable Maintainer. Both machines individually treat clothes and then fold them onto a shelf.

Another source suggests slightly higher temperatures, for example, 180-220 °C for cotton [2]

Chemistry

When the fabric is heated, the molecules are more easily reoriented. In the case of cotton fibres, which are derivatives of cellulose, the hydroxyl groups that crosslink the cellulose polymer chains are reformed at high temperatures, and become somewhat "locked in place" upon cooling the item. In permanent press pressed clothes, chemical agents such as dimethylol ethylene urea are added as crosslinking agents.

Laundry refers to the washing of clothing and other textiles, and, more broadly, their drying and ironing as well. Laundry has been part of history since humans began to wear clothes, so the methods by which different cultures have dealt with this universal human need are of interest to several branches of scholarship. Laundry work has traditionally been highly gendered, with the responsibility in most cultures falling to women. The Industrial Revolution gradually led to mechanized solutions to laundry work, notably the washing machine and later the tumble dryer. Laundry, like cooking and child care, is still done both at home and by commercial establishments outside the home.

Cellulose triacetate, triacetate, CTA or TAC is a chemical compound produced from cellulose and a source of acetate esters, typically acetic anhydride. Triacetate is commonly used for the creation of fibres and film base. It is chemically similar to cellulose acetate. Its distinguishing characteristic is that in triacetate, at least "92 percent of the hydroxyl groups are acetylated." During the manufacture of triacetate, the cellulose is completely acetylated; whereas in normal cellulose acetate or cellulose diacetate, it is only partially acetylated. Triacetate is significantly more heat resistant than cellulose acetate.

A fabric softener or fabric conditioner is a conditioner that is applied to laundry during the rinse cycle in a washing machine to reduce harshness in clothes that are dried in air after machine washing. In contrast to laundry detergents, fabric softeners may be regarded as a kind of after-treatment laundry aid.

Sanforization is a treatment for fabrics to reduce shrinkage from washing. The process was patented by Sanford Lockwood Cluett (1874–1968) in 1930. It works by stretching, shrinking and fixing the woven cloth in both length and width before cutting and producing, to reduce the shrinkage which would otherwise occur after washing. The original patent mentioned "goods of cotton, linen, woolen, silk, rayon, and combinations thereof".

<span class="mw-page-title-main">Finishing (textiles)</span> Manufacturing process

In textile manufacturing, finishing refers to the processes that convert the woven or knitted cloth into a usable material and more specifically to any process performed after dyeing the yarn or fabric to improve the look, performance, or "hand" (feel) of the finish textile or clothing. The precise meaning depends on context.

Dimensional stability is the change of dimensions in textile products when they are washed or relaxed. The change is always expressed relative to the dimensions before the exposure of washing or relaxing. Shrinkage is also called residual shrinkage and measured in percentage. The major cause of shrinkages is the release of stresses and strains introduced in manufacturing processes. Textile manufacturing is based on the conversion of fiber into yarn, yarn into fabric, includes spinning, weaving, or knitting, etc. The fabric passes through many inevitable changes and mechanical forces during this journey. When the products are immersed in water, the water acts as a relaxing medium, and all stresses and strains are relaxed and the fabric tries to come back to its original state. The dimensional stability of textile materials is an important quality parameter. Failing and unstable materials can cause deforming of the garments or products. Shrinkage is tested at various stages, but most importantly before cutting the fabric into further sewn products and after cutting and sewing prior to supplying the products to buyers and consumers. It is a required parameter of quality control to ensure the sizes of the products to avoid any complaints regarding deformation or change in dimensions after domestic laundry. The tests are conducted with provided specifications of buyers imitating the same conditions like washing cycle time, temperature and water ratio and fabric load and sometimes top loading and front loading washing machines are chosen to authenticate the test and assurance of the results. This procedure provides standard and alternate home laundering conditions using an automatic washing machine. While the procedure includes several options, it is not possible to include every existing combination of laundering parameters. The test is applicable to all fabrics and end products suitable for home laundering.

<span class="mw-page-title-main">Dimethylol ethylene urea</span> Chemical compound

Dimethylol ethyleneurea is an organic compound derived from formaldehyde and urea. It is a colourless solid that is used for treating cellulose-based heavy fabrics to inhibit wrinkle formation. Dimethylol ethylene urea (DMEU) bonds with the hydroxyl groups present in long cellulose chains and prevents the formation hydrogen bonding between the chains, the primary cause of wrinkling. This treatment produces permanently wrinkle-resistant fabrics and is different from the effects achieved from using fabric softeners. An additional names for DMEU includes 1,3-bis(hydroxymethyl)-tetrahydro-2-imidazolone.

Wet Processing Engineering is one of the major streams in Textile Engineering or Textile manufacturing which refers to the engineering of textile chemical processes and associated applied science. The other three streams in textile engineering are yarn engineering, fabric engineering, and apparel engineering. The processes of this stream are involved or carried out in an aqueous stage. Hence, it is called a wet process which usually covers pre-treatment, dyeing, printing, and finishing.

<span class="mw-page-title-main">Clothes steamer</span> Device used to remove wrinkles from garments and fabrics

A clothes steamer, also called a garment steamer or simply a steamer, is a device used for quickly removing wrinkles from garments and fabrics with the use of high temperature steam. They can for example be used to straighten wrinkles on shirts by releasing tension in the fabric so that it straightens itself. Steamers can also remove smells.

Wrinkle-resistant or permanent press or durable press is a finishing method for textiles that avoids creases and wrinkles and provides a better appearance for the articles. Most cellulosic fabrics and blends of cellulosic rich fabrics tend to crease or wrinkle. A durable press finish makes them dimensionally stable and crease free. The finishing includes chemical finishing as well as mechanical finishing. Wrinkle-resistant finishes were developed in the early 20th century, as a way to deal with fabrics derived from cotton, rayon, and linen, which were found to wrinkle easily and retain the wrinkles. These treatments have a lasting effect on the fabric. Synthetics like polyester, nylon, acrylic and olefin, have a natural resistance to wrinkles and a greater stability since they do not absorb water as efficiently.

<span class="mw-page-title-main">Fabric treatment</span>

Fabric treatments are processes that make fabric softer, or water resistant, or enhance dye penetration after they are woven. Fabric treatments get applied when the textile itself cannot add other properties. Treatments include, scrim, foam lamination, fabric protector or stain repellent, anti microbial and flame retardant.
