“…Many harmful chemical methods are used to change the surface property to improve fibres hydrophilicity. Currently, plasma discharge appears as an environmental friendly alternative treatment to improve the dyeability of wool . Kan et al treated wool with oxygen plasma and dyed with acids, reactive and metal complex dyes.…”

Plasma technology applied to textiles is a dry, environmentally‐ and worker‐friendly method to achieve surface alteration without modifying the bulk properties of different materials. In particular, atmospheric non‐thermal plasmas are suited because most textile materials are heat sensitive polymers and applicable in a continuous processes. In the last years plasma technology has become a very active, high growth research field, assuming a great importance among all available material surface modifications in textile industry. The main objective of this review is to provide a critical update on the current state of art relating plasma technologies applied to textile industry.

“…The use of carbohydrate polymers after alkali damage partially restored the fabric strength, particularly when cationic chitosan was used. The treatment of damaged wool fabrics with chitosan resulted in a partial recovery of the strength loss (17.3 MPa), in harmony with previous studies showing improvements in mechanical strength with chitosan treatments . This may be attributed to the strong ionic and/or covalent crosslinking of chitosan with the polar groups of wool keratin, creating a durable chitosan surface layer, which can partially remedy the negative effects of alkali exposure on fabric mechanical strength and surface morphology.…”

“…Many of them possess unusual physicochemical and biological characteristics. Polymers such as chitosan are used to improve a variety of fabric properties . One application of chitosan treatment with significant potential, but that has not yet been well‐developed, is restoration of the desirable characteristics in wool fabrics damaged seriously during textile processing.…”

Wool is a natural composite material consisting of keratin and keratin-associated proteins as the key molecular components. During wool product processing, a variety of chemical and enzymatic reagents are used, the side-effects of which can include the removal of the outside layers of the fiber (cuticle) and damage within the internal protein matrix of the fiber. This can reduce the mechanical strength and durability of wool fabrics. We report the use of neutral, cationic, and anionic carbohydrate polymers, namely 2-hydroxyethyl cellulose, chitosan and alginate, as repair agents to improve the mechanical properties and morphology of wool fabrics damaged under harsh alkaline conditions. Tensile strength, peel adhesion, scanning electron micrographs, and fabric wettability evaluation reveal the cationic polymer, chitosan, to be most effective at remedying the effects of the alkaline treatment. The improved mechanical properties observed after chitosan treatment may offer viable remediation routes for adding value to processing-damaged wool textiles.
