Durable antimicrobial functions

Cetylpyridinium chloride (CPC) was used to form ionic bonds with Acrilan (acrylonitrile copolymer) woven fabrics in order to confer antimicrobial functions to the fabrics. The finished fabrics showed good efficacy against Escherichia coli and the washing durability of the antimicrobial properties was excellent. The CPC uptake on the Acrilan fibres depended on the pH during the finishing process, concentration of the CPC and the finishing temperature. High pH and temperatures were... 

Using microcapsules technique, by ionic gelatin, enhanced the durability of the imparted antimicrobial functionality even after 15 washes -The antimicrobial activity against both E. coli, and S. aureus bacteria followed the decreasing order S. aureus > E. coU... 

The functionalized cotton fabrics showed a remarkable durable antimicrobial activity against G-fve and G-ve bacteria... 

Housekeeping Goods From wipes, mops, sponges to other cleaning supplies, engineered fabrics have utility and with an antimicrobial finish, serve a more durable and functional life. 

The resultant fabrics are unique in that they have many functional property improvements thermal adaptability due to the phase change nature of the bound polyol, durable press or resiliency, soil release, reduction of static charge, antimicrobial activity, enhanced hydrophilicity and improved flex life, and resistance to pilling. Because of the different molecular weights of polyols, resins, acid catalysts, and fabric constructions, there are numerous modified fabrics that can be produced with sets of improved attributes. Each fabric must be carefully evaluated for optimum curing conditions and formulations to produce the desired product. Several licenses have been granted for this process. Various types of apparel, healthcare items, and industrial fabrics are currently evaluated for commercial production [381,382]. 

Consequently, the need for innovative, cleaner, durable, comfortable, cost-efficient, and value-added functionalized cellulosic textile products, e.g., antimicrobial, UV protection, self-cleaning, easy care, soft-handle, insect repellent, water/oll repellent, antiodor and fragrance finished, etc., are still a challenge [12,47,91, 111, 127]. 

Peroxide pretreatment of cotton fabrics showed better antimicrobial activity that their corresponding intact ones -The imparted antimicrobial activity was governed by the t5T)e of bio-active material and followed the decreasing order Aloe vera > chitosan > curcumin -Combination of the above-mentioned bio-active agent resulted in an enhancement in both the activity and durability of the imparted functional properties to cotton fabrics. 

It has been demonstrated in recent years that the nanotechnology can be applied to textiles to enhance various properties, especially in functional coatings, such as fabric softness, durability and breathability, water repellency, fire retardency, antimicrobial properties, anticrease properties, UV protection, self-cleaning properties and like in fiber, yarn and fabrics [131, 134-136]. Undyable polypropylene fiber can be made dyeable by... 

Further work could be carried out in order to extend the durability of the antimicrobial property by using different cross-linking agents. The fabric can be functionally enhanced by applying other surface finishes, such as to improve the handle of the fabric. The durability aspect of the antimicrobial finish can be studied over larger number of washes than those conducted during this study. The fabric can also be functionally enhanced by applying other types of finishes. 

Multifunctional Materials. Multifunctional property improvement by binding of specific polymers to fibers and fibrous products has been extensively investigated and reviewed (81). With poly(ethylene glycol) as the bound polymer, functional and aesthetic property improvements include thermal comfort, liquid absorbency/repellancy, increased wear life, soil release, resistance to static charge, antimicrobial activity, and resiliency. Numerous applications such as sportswear/ski wear, protective clothing for health care workers, durable and nondurable hygienic items, work uniforms, and space suits are being commercialized and evaluated.
