Tumble-drying

Thus, if the fabric is flat and smooth, it will tumble dry in that configuration. On the other hand, if the fabric is cross-linked in a creased condition, as in a pleated skirt, the original pleated skirt configuration should return on laundering and tumble drying. 

Eabric can be cross-linked either in the dry or the wet state. If fabric is cross-linked in the dry state, smoothness returns on tumble drying. By contrast, if fabric is cross-linked in the wet state, smoothness is achieved byline-drying the fabric. This concept has been demonstrated using formaldehyde in pad—dry—cure or wet cure processes (eq. 2) (29).

A rotary drum had been used previously to dry metal components which had been heat-treated in nitrate—nitrite molten salt baths, washed, then tumble dried with ground maize husks to absorb adhering water. When the drum was taken out of service, it was not cleaned out. After some 10 months it was recommissioned, but while being heated up to operating temperature, an explosion occurred which ejected flame jets for several m. This was attributed to presence of considerable contamination of the maize husks by metal nitrate—nitrite residues, and ignition on heating of such material was confirmed experimentally. 

Improvements in detergent efficacy will continue to capture the undivided attention of detergent manufacturers. There are multiple approaches that encompass a wide variety of current and novel technologies. Examples of these types of approaches range from unique combinations of enzymes (pectate, lyase, and mannanase) to facilitate the removal of food soil residues, to ethoxylated quaternized amines to improve soil suspension and cleaning of outdoor soils/stains, to nanoparticle technologies to deliver crease resistance properties in tumble dry additives and aqueous ironing formulations [180],... 

Because of the static electricity imparted to synthetic fabrics by tumble drying, and the increasing proportion of synthetic fabrics in the U.S., the sales of dryer-sheet fabric softener rose much more in the U.S. than in the rest of the world. By 1983, these products accounted for 40% of all household fabric softener sales. Today, tumble dryer sheets and liquid softener sales are of the same order of magnitude [5,6,16], In contrast, rinse-added softeners had a much larger impact in Europe, where 100% cotton items have always been dominant and line drying is still standard practice hence, the softener effect is more noticeable to consumers. 

Electrical tumble dryers are much more popular in the U.S. than in Europe (see Section IV). Consequently the market penetration of dryer cycle fabric softeners is much more important in North America than anywhere else. They are usually based on the same types of actives as the rinse cycle fabric softeners [35], Two methods of delivery exist. Nonwoven sheets are impregnated with cationic softener that are incorporated in the wet load at the start of tumble drying or a fabric conditioner is sprayed from an aerosol onto the empty dryer drum before the drying process [16]. 

The breakdown of energy for piece of cotton T-shirt shows that transportation, material, production, and disposal phases are dwarfed by the use phase. The use phase includes 25 washes at 60 °C, followed by tumble drying and ironing, that consume 60% of the total energy. The disposal phase includes incineration in which heat is generated and used so the net energy consumption is negative in this phase.

Eco release (Devan Chemicals) is an easy-care finish that maintains its stain-release performance after washing without tumble drying or ironing. The product contains fluorine (not in the form of C8 or C6) and is characterized by dual-action technology repellency and release.
