A report is given on new methods of surface modification of near-skin textiles. These modifications include the use of cyclodextrins, linear carbohydrate biopolymers and inorganic/organic hybrid networks; all of them can be permanently fixed on the textile for multiple uses. Textiles finished in this way may be used as transdermal therapeutic systems after loading with pharmaceuticals or as transdermal collector systems for stabilizing and analysing sweat components or as a means to regulate the skin climate.

“…Modification of surfaces with cyclodextrins (CDs) in order to obtain new functionalities has been the subject of many studies the past years. [1][2][3][4][5] CDs are cyclic oligosaccharides most often consisting of 6, 7, or 8 a-1,4 linked glucose units, designated a-, b-, and c-CD, respectively. 6 Because of the unique structure of the CDs with a hydrophilic exterior and a hydrophobic-like interior, the CDs have an inherent ability to form inclusion complexes with various hydrophobic molecules.…”

In this study six amphiphilic cyclodextrin derivatives were prepared by esterification and used to coat five industrial products made from polypropylene, polyethylene, polyvinyl chloride, or polyurethane using a new, patented coating technology. This simple approach, which consists merely of dipping the material to be coated into a suspension of a given cyclodextrin derivative in an ethanol/water solution, was used to functionalize support materials with a coat that is stable in aqueous solutions and which renders the coated materials hydrophilic. The functionalization proved to be controllable in terms of amount of cyclodextrin on the surface and can be implemented in existing production lines without investment in advanced production equipment. It is hypothesized that the cyclodextrins order themselves in structured layers forming channel-like structures preserving the very large potential for uptake and release of active compounds that is known to cyclodextrins.

“…[1][2][3][4][5] Modificações químicas das CDs naturais, como a introdução de um grupo reativo, aumentam a sua aplicabilidade para diversas finalidades como, por exemplo, a ancoragem permanente em substratos poliméricos. [6][7][8][9] Entre as moléculas hospedeiras as CDs ocupam um espaço importante devido à produção econômica em larga escala, que permite sua utilização em nível industrial, à baixa toxicidade e à possibilidade de serem empregadas para consumo humano como auxiliares na formulação de drogas, alimentos, e de cosméticos. 1,10,11 A indústria têxtil representa uma parte importante da economia brasileira e mundial e como todas as indústrias tradicionais está numa constante busca por processos mais eficientes, econômicos e ecologicamente mais corretos.…”

Recebido em 15/4/09; aceito em 30/11/09; publicado na web em 8/4/10 APPLICATION OF CYCLODEXTRINS IN TEXTILE PROCESSES. Cyclodextrins (CDs) are water soluble cyclic sugars with a hydrophobic nanometric cavity that permits the formation of host/guest inclusion complexes with a large variety of molecules, alternating their physical-chemical properties. In the present review CD research related to the processing of textiles is revised and discussed. CDs may function as encapsulating, dispersing and levelling agents in the dyeing and washing of textiles. Furthermore they may be anchored to polymers and textile fibers in order to impart special properties such as odor reduction, UV protection or for the controlled release of perfumes, aromas, mosquito repellents or substances with therapeutical effects.CDs são oligossacarídeos cíclicos compostos de unidades de D-(+)-glicopiranose unidas por ligações a-1,4. A estrutura da CD é um anel cilíndrico cônico truncado. As hidroxilas secundárias estão situadas na parte onde o diâmetro do anel é maior, e as hidroxilas primárias, onde o diâmetro do anel é menor. 2,16,17 Dependendo do número de unidades glicosídicas na molécula os anéis assumem diâmetros internos de diferentes tamanhos (Tabela 1). As CDs naturais mais importantes e comercialmente fornecidos por diversos fabricantes são a-, b-, g-CDs, cujas cavidades são formadas, respectivamente, por 6, 7 e 8 unidades de D-(+)-glicopiranose (Figura 1). 2,12,[17][18][19]
