- these chains make it possible, after crosslinking, to form an elastomeric silicone-based material which, in addition to its hydrophobic properties, is naturally soft, supple, compatible with the skin and hypoallergenic.
- PDMS chains may have, along said chain, functional groups that are reactive under ionizing radiation.
- said chains may be crosslinked with each other and / or with another reactive material such as, for example, di or trifunctional agents or a textile substrate also having reactive functionalities under ionizing radiation.
- the formulation comprises an oil or a mixture of oils comprising PDMS chains.
- the formulation may comprise a mixture of at least one oil comprising functionalized PDMS chains and / or one or more oils comprising non-functionalized PDMS chains.
- the functionalization method provides for forming with said formulation a discontinuous layer on a surface of the textile substrate.
- a network of discrete patterns, including dots on the surface of the textile substrate, in particular by screen printing, etching, spraying, inkjet, lithography, transfer.
- the discontinuous layer may be formed by depositing a continuous layer of the formulation on the surface of the textile substrate, and then treating said layer to make it discontinuous.
- the continuous layer can be deposited by transfer and then stretched mechanically to make it discontinuous by cracking of said continuous layer.
- it can add to the formulation of the layer additives capable of promoting the creation of porosity and / or discontinuity in said layer.
- the formulation may be arranged to promote the impregnation of the surface of the textile substrate by the discontinuous layer formed, in particular by comprising a wetting agent.
- the formulation may comprise other additives such as rheology or thixotropic agents but also resins, gums, adhesion promoters or reactive compounds comprising SiH groups.
- the formulation can be prepared using at least one oil in pure form, in emulsion or in dispersion.
- a typical example of formulation may include the following mixture:
- a formulation is a mixture of this type which is emulsified in an aqueous portion of between 35 and 85%. Both parts can be bound by surfactants and emulsifiers (between 0.5 and 5%).
- the rheology can be adjusted with a thixotropic agent that can be of the polyurethane type (between 0.2 and 2%), and the wettability on the substrate by the addition of a wetting agent (between 0.3 and 3%).
- the functionalization method provides for applying ionizing radiation to the discontinuous layer so as to ensure the grafting of the hydrophobic material on the surface of the substrate by reaction of the reactive groups.
- the ionizing radiation is electron bombardment generated by an electron accelerator which, when using PDMS chains, is adjusted in power and duration to allow cross-linking and grafting of said chains.
- the method may also provide a heat treatment step of the discontinuous layer formed and / or grafted, for example by means of lamps infrared, so as to ensure the drying of the textile substrate.
- the heat treatment may also make it possible to heat-fix the formulation on the textile substrate.
- the textile substrate can be washed and then dried or undergo other treatments necessary for its subsequent use.
