“…The advantages of this technology are well known: energy savings (lowtemperature process), low environmental impact (no solvent emissions), simple, cheap, small equipment, and high treatment speed. Despite these advantages, there have been few applications of radiation curing in the textile industry, such as nonwoven fabric bonding, fabric coating, pigment printing, silk grafting, and surface modification of cotton and synthetic fibers [73,74]. In fact, in textile finishing processes, the conventional thermal curing technique is still used, regardless of energy consumption and cost.…”

The modification of the surface energy of textile fibers to improve functional properties such as the wettability was reviewed. This modification can be achieved by physical or chemical methods or by the combination of both. Applications of plasma treatment to improve the wettability of natural and synthetic fibers were considered and some methods of wettability measurement were mentioned. Subsequently the methods aimed to confer water and oil repellency were discussed and the treatment by UV curing of fluorochemicals was explained in detail. Finally the sol-gel techniques useful to modify the surface properties of textiles were introduced and the results of water and oil repellency achievable by sol-gel were presented.

“…It is well known that the epoxy ring of these crosslinkers is reactive toward various nucleophilic groups of amines or hydroxyl without by-product elimination. [42][43][44] Finally, the wettability, antimicrobial activity, whiteness and stiffness of the modified polypropylene woven fabric are analyzed, respectively.…”

In order to realize the immobilization of collagen, chitosan and sericin on the surface of polypropylene fabric, the fabric is treated by ammonia and nitrogen low temperature plasma to produce reactive groups, and then the epoxy compounds (ethylene glycol diglycidyl ether, trimethylolpropane triglycidyl ether) are used as crosslinkers for a bridging process. Single factor experiment is carried out to investigate the influence of crosslinking parameters (temperature, time and the dosage of crosslinker) on immobilization yield. Chemical composition changes on the surface of the treated samples is analyzed by infrared spectroscopy, which indicated that the ammonia plasma treatment can produce more active groups. The results showed that immobilization rate of samples crosslinked by ethylene glycol diglycidyl ether is superior to that of trimethylolpropane triglycidyl ether. It also can be found that the fabric had a better wettability and antimicrobial properties. The whiteness and comfort property of chitosan-polypropylene fabric decreased slightly.

“…(3) limited treatment costs, without precluding any market segment; and (4) environmentally friendly requirements, for sustainable textile processes. Many research works were developed with the aim to utilize the effects of UV radiations on various natural as well as synthetic fibers [1][2][3][4][5][6]. Most of these studies were devoted to the surface modification of wool, but even cotton fiber was considered.…”

Ultraviolet (UV) radiations can act in different ways on the functionalization of textiles, through pre-or posttreatments, in order to modify their behavior in dyeing and finishing processes. In cotton fiber, unlike the wool, the UV absorption is not due to any of the structural groups of the normal cellulosic chains and can only be attributed to "impurities" or "faults" bearing carbonyl and/or carboxyl groups. In fact, UV irradiation coupled with mild oxidation can improve some properties of the cotton fibers such as pilling resistance, water swelling, and dyeability. Therefore, the process of differential dyeing with direct and reactive dyes assisted by UV irradiation was studied and interesting differential chromatic effects were obtained by a UV posttreatment capable to fade dyeing. On the other hand, the surface modification of cotton fabrics by UV curing and UV grafting with suitable chemicals was pursued to obtain finishing treatments able to confer oil and/or water repellency. Finally, antimicrobial finishing by chitosan UV grafting was proposed as valid environmental friendly method to confer a satisfactory washing-resistant antimicrobial activity to cotton fabrics even with low polymer add-on.
