“…partially or fully methylated DMDHEU (Patricia 2012). Reactivity is further reduced by reaction with methanol or diethylene glycol (producing ultra-low formaldehyde release) leading to ether modified DMDHEU products with low formaldehyde release (Holme 1993). These products possess improved stability and poor DP performance than that of its precursor but are acceptable due to comparatively less formaldehyde release because of end-caps present in it.…”

Cotton apparels possess inherent tendency to form wrinkles under external stress. Conventionally selective cross-linking agents in presence of specific catalyst are applied on cotton to supress formation of creases or wrinkles via pad-dry-cure technique at high curing temperature under acidic conditions imparting stability and elasticity to the fabric. Extensive research carried out in this field identifies invariable deterioration in mechanical properties of finished cotton. In this study, two different cross-linking agents, i.e. modified DMDHEU and citric acid working on etherification and esterification crosslinking reaction with cellulose respectively were applied on cotton through selection of factors using Box Behnken experimental design in conjunction with response surface analysis and regression methods to study their DP ratings as well as other mechanical properties. Significant factors were further drastically narrowed down to reach to most specific concentrations of cross-linker, catalyst as well as other chemicals along with finishing parameters. It was found that modified DMDHEU performed better in terms of DP rating as well as overall physical properties as compared to those obtained with citric acid.

“…It is important to note that the fabrics in the current study were laundered once prior to any experimental being conducted, whereas, in use chefs' clothing would be repeatedly laundered. The durability of the finishing treatment applied to a fabric is vital to maintain the necessary performance properties of water/stain repellency or soil release (Gibson 2006;Holme 1993). The durability of the finishing treatments to repeated laundering was not assessed in this study.…”

“…Repellent finishes applied to a fabric, opposed to a waterproof membrane or coating, are particularly important when an important characteristic of the fabric is that it remains permeable to air, and hence allows water vapor to easily permeate (Gibson 2006;Holme 1993). Therefore, finishes which impart repellency to water and other liquids could also offer protection against scald injuries as hot water and other hot liquids may bead and run off the fabric rather than being absorbed into the fabric.…”

“…Soil-release finishes, intended to make laundering more effective may be applied to fabrics with polyester fibers or wrinkle-resistant treated cotton fabrics. Since most soils are hydrophobic, the soil-release finishes tend to make the fiber surface more hydrophilic and thereby allow the diffusion of water and detergent into the soil-fiber interface and decreases the adhesion of the soil to the fibers (Holme 1993;Kissa 1981). Fluorochemicals are the most interesting class of chemical for textile finishing as they provide combined water and oil repellency to fabrics (Holme 1993).…”

Can common finishing treatments used in chef jacket fabrics improve protection against scald injury?

Chefs and other food preparation workers are at a high risk of scald injuries from hot liquids. Chefs’ clothing has the potential to act as a protective barrier between the skin and the thermal hazard. Although, impermeable barriers coupled with an insulating layer of fabric tend to offer the greatest protection against hot liquid penetration, the potential for heat strain and discomfort to workers may make them impractical in the kitchen environment. This study examined the effects of common finishing treatments used in chef jacket fabrics and the impact of layers on the protection offered against hot water burn injuries. The Teflon® treated fabrics offering combined stain and water repellency, provided the greatest protection with the lowest absorbed energy and longest times to second degree burn injury compared with the other finishes (i.e., regular, water repellent and soil release). Findings also showed that in most cases, increasing the number of layers improved protection provided by the fabric systems, with the Teflon® finished fabrics providing the highest protection against scald injuries as fabric layers increased.

Textile finishing includes various efforts to improve the properties of textile fabrics, whether for apparel, home, or other end uses. In particular, these processes are directed toward modifying either the fiber characteristics themselves or the gross textile end properties. Such modifications may be chemical or mechanical in nature. One modification that is not covered in this article relates to the dyeing of textiles and the dyestuffs employed for fibers; however, areas that involve chemical finishing designed to modify the normal dye receptivity and the growing use of enzyme treatments are included.Fibers have been used by humans for thousands of years, but only in the twentieth century has there been such an explosion in fiber types available to the textile manufacturer. The advent of synthetic fibers possessing improved resiliency and dimensional stability has placed natural fibers, particularly cotton (qv), at an ostensible disadvantage. Before synthetics, various means to control the shrinkage, dimensional stability, and smooth-dry performance of cotton had been investigated, but the appearance of synthetics such as polyester has placed a greater sense of urgency on cotton interests to focus on the perceived deficiencies of natural fibers.Textile finishing encompasses a broad range of approaches and may be directed toward needed properties such as shrinkage control or smooth-dry performance or toward developing properties for specific end uses such as flame retardance, soil release, smolder resistance, weather resistance, or control of static charges.From a historical point of view, mechanical finishing processes have been directed toward improving shrink resistance via compressive shrinkage (Sanforized process) or calender finishing to give surface effects, which include shreinering, chintz finishing, and embossing. These latter effects are semidurable, and can be made more permanent by cross-linking with resins. However, such cross-linked fabrics seem to suffer greater loss in tearing strength when cross-linked in the calendered state. The need for calendered fabrics has decreased with the advent of cross-linked cotton, but compressive shrinkage to control garment shrinkage remains a significant component in textile mill practice, particularly for products that receive little or no resin treatments.For fabrics of thermoplastic fibers, permanent effects are obtainable if heat and pressure are applied to soften the material. Processes dealing with carpets, nonwovens, and chemical modifications or additions that occur before the fiber is formed are not discussed herein (see Nonwoven fabrics).
