can also be applied in fine textiles by padding with a binder in machines with squeezing rollers normally they are not applied by exhaustion process since they do not have affinity for the fibres even if they are applied by exhaustion process the woven or knitted fabric needs to be padded with a binder and the microcapsules later thermally bound by the thermoplastic binder at high temperatures in an appropriate machine usually a stenter in the invention we are proposing the set of direct bonds between individual microcapsules and the fibres has several advantages relatively to the use of binding materials containing microcapsules since the use of binders has many disadvantages other than the lack of durability of the microcapsules to friction and washes causing namely a lack of flexibility of the textile materials a higher impermeabilization to transpiration causing therefore discomfort and in materials in contact with the skin they cause a harsh handle in this process that we are claiming microcapsules are chemically bound to the fibres without resorting to binders the durability of the microcapsules is higher than that of the process of application by binding microcapsules with binders in this invention that we are claiming instead of the usage of binders that fix onto fibres microcapsules containing functional reactive groups are used binding the microcapsules directly to the fibres the functional groups are introduced into the microcapsules of urea formaldehyde melamine formaldehyde polyamide or chitosan reacting with the amino nh 2 or hydroxyl oh groups present in these microcapsules as an alternative microcapsules for example with a second shell on top of the urea or melamine formaldehyde shell can be used made of polymers containing functional groups poly glycidyl methacrylate or any other polymer that may contain epoxy glycidyl groups polyacrylic acid containing carboxylic.
