“…6, for the wool fiber presents as main bands: 1,079 cm -1 vibration of the functional group S=O; 1,172 cm -1 Strong C-O stretching of primary alcohols and phenols; 1,395 cm -1 axial deformation of the carbonyl group C=O from carboxylic acid; 1,630 cm -1 vibration of the carbonyl functional group C=O primary amide; 3,072 cm -1 stretching, NH 2 associated with primary aliphatic amines; 3,276 cm -1 vibration of the axial deformation of the O-H bonding [46]. The variety of functional groups in wool comes from the protein structure [16], allowing an interaction with many finishing products [17]. New peaks are originated in the treated wool fabric in a region between 700 -950 cm -1 .…”

“…Many textile fibers were already used as a support for cyclodextrin, such as cotton [6,10], polyester [11,12] and wool [13,14]. One of the most popular fibers, which is nowadays employed in textile products of high quality, is wool [15], a protein fiber consisting mainly of keratin [16]. Due to the protein structure, wool has many different chemical groups, such as OH, NH 2 , COOH, etc.…”

The use of biopolymers such as cyclodextrin in textiles for the development of biofunctional fabrics is an alternative for the development of eco-friendly textiles. Cyclodextrins can create covalent interactions with the chemical groups available in wool, allowing the sorption of active molecules that will be released, such as the citronella oil. Therefore, this work investigates the formation of cyclodextrin complex oil applied in wool and its release mechanism. The complexes obtained and the grafted fabric were characterized by TGA, DLS, FTIR-ATR and SEM. The release of citronella oil was also analyzed and mathematical adjustments were performed using the equation of Korsmeyer-Peppas to verify the release mechanism. The results have indicated the formation of the complex and its fixation by covalent bonding, according to the FTIR-ATR specter and the SEM, and these have shown an anomalous release profile. For this reason, the application of the complexes in wool fabrics has shown to be an option in the production of eco-friendly biofunctional materials for controlled release, allowing the oil properties to be used in textile matrices.

“…For the controlled surface hydrolysis of wool, authors of papers [3,4] proposed using bromelain, a proteolytic enzyme, active in acidic medium. It was proved that treatment with bromelain in the presence of sodium chloride at pH 6, provides a desirable antifelting degree with a decrease in weight and strength loss, compared to enzymatic treatment in alkaline medium.…”

The enzymes have been gaining more importance in different fields, among the most important the pharmaceutical field. However, due to the protein nature of the enzymes, a significant part of them presents high instability under certain conditions of use. A great way to stabilize them is to use immobilization techniques. Bromelain from pineapple has shown potential to be used in the treatment of burn-like skin injuries and superficial injuries. Biocatalytic textile fibers from cellulose of sugarcane bagasse were prepared using surface functionalization with epichlorohydrin (4% v/v) and glutaraldehyde (0.5% v/v), and 1-ethyl-(3-dimethylaminopropyl) carbodiimide and bromelain immobilization by covalent bonding in the fibers. The best immobilization results for the bromelain enzyme immobilization were using the aminopropyltriethoxysilane and glutaraldehyde activating agent at pH 7 to values of 68.97% and 88.14% for total protein content and enzyme activity, respectively. Considering the approach described in this paper, others advanced materials from pulp fibers and bioprocesses might be developed using bromelain and other enzymes for the target applications.
