Textiles, drying

Used industrially as a fungicide, insecticide, herbicide, wood preservation, textile drying agent, corrosion inhibitor as a veterinary medication and in the manufacture of specialty soaps. 

The other hydrocarbon acids arc not a industrially significant. In many potential markets the lower price of acetic acid keeps them blocked out. Formic acid is used in textile drying and leather treatment. Propionic acid is used in the production of propionates, plasticizers, and herbicides Butyric acid finds a variety of specialty uses in producing plasticizers and esters. 

It has been reeognized that microwaves could perform a useful fimction in textile drying in the leveling out of moisture profiles across a wet sample. This is not surprising because water is more reaetive than any other material to dielectric heating so that water removal is aeeelerated. An exponential model presented here. [7] can be used to describe the drying eurves. 

Stenters (Tenters) and Textile Dryers These are the basic type of dryer used for sheets or webs in the textile industry. The sheet is held by its edges by clips (clip stenter) or pins (pin stenter), which not only suspend the sheet but also keep it taut and regulate its width—a vit consideration in textile drying. Drying is by convection hot air is introduced from one or both sides, passes over the surface of the sheet, and permeates through it. Infrared panels may also be used to supply additional heat. A schematic diagram of the unit is shown in Fig. 12-88. A typical unit is 1.4 m wide and handles 2 to 4 t/h of material.

Barker and Christie described a microprocessor-based control system for the control of textile drying processes [33]. In addition to the control of the dryer outlet moisture content, the computer-based system was used to optimize the energy use of the dryer.

To make washing active to clean oils, fat and grease from textiles, soap (detergent) has to be added to water. To make dry cleaning active to clean salts, sugar and the like from textiles, dry cleaning detergent has to be added to the solvent. 

Some nanocomposites recently became commercially available and were applied to the automotive and food packaging industries. These studies will further broaden the applications of these materials in medical instrument engineering, electronic engineering, civil engineering, energy, textiles, dry/wet adhesives and fasteners, engineering structures, household products, optical materials, etc. 

Yasinskaya et al. (2011) studied flexural strength and thermal conductivity of poly ester/acrylic and polyester/wool insulating tiles as a function of polyester proportion in the mixture and volume density. The analysis of regression equations enabled the optimum combination of factors to be found which provides the required thermal insulation and mechanical properties of the tiles. Karthik and Murugan (2013) optimized the spinning parameters of DREF-3 system. Akyol et al. (2013) considered an industrial textile drying process.
