Binder effectiveness of microcapsules applied onto cotton fabrics during laundry

Abstract

Microcapsules can be added to fabric in industrial processes however, they have not been widely spread among industrial companies. In this study we suggest the possibility of reloading microcapsules onto a fabric while cloths are washed. The effectiveness of different resins when microcapsules are applied in washing machine during domestic laundry process has been studied.Microcapsules containing lavender fragrance and melamine formaldehyde shell where adhered to the fabric by means of one acrylic acid as a resin, or some crosslinking agents such as butanetetracarboxylic acid (BTCA) or succinic acid (SUC). In order to evaluate their behaviour some laundering or ironing tests were conducted according to international standards (ISO). Every sample from the laboratory was studied with Scanning Electron Microscopy (SEM) and with a particle size counter. As a result we could observe which was the most suitable auxiliary used to bond microcapsules to fabric, and conclude about the conditions (temperature, concentration, etc.) in which we obtained the optimal results. It was demonstrated that domestic laundry is a suitable process to incorporate microcapsules to garments.

Potential use of microcapsules in manufacture of fibrous products: A review

“…Besides the industrial processes for adding the microcapsules to fibrous materials, the possibility of reloading microcapsules during laundry is known. For instance, this possibility was investigated by Aracil et al . In this study, the effectiveness of binders as acrylic resin, polycarboxylic acids, butanetetracarboxylic acid, and succinic acid was examined onto cotton fabrics.…”

Binder Effectiveness on Cotton Fabric Finishing With Microcapsules Using Padding

“…Untuk meningkatkan kekuatan mekanis, seperti ketahanan mikrokapsul terhadap pencucian maka dapat dilakukan melalui beberapa cara diantaranya adalah memilih teknik aplikasi, zat pembantu, dan bahan penyalut yang sesuai. 17 Mikrokapsul dapat ditambahkan pada kain melalui beberapa teknik, diantaranya adalah perendaman (exhaust), padding (pad-dry-cure), penyemprotan (spraying), dan laundry tanpa merubah handfeel dan warna kain. 3,16 Teknik perendaman lebih sesuai untuk proses yang didalamnya terdapat reaksi kimia seperti pemutihan dan pewarnaan.…”

“…Oleh karena itu diperlukan sebuah zat pembantu yang dapat menahan mikrokapsul pada permukaan kain, salah satunya binder. 17 Tetapi, pada saat pencucian terdapat gerakan mekanis yang mampu merusak sebagian gaya adesi yang terjadi antara binder, kain, dan mikrokapsul, akibatnya lapisan binder (poliakrilat maupun poliuretan) yang terbentuk menjadi lebih tipis sehingga kain menjadi lebih ringan.…”

“…Tetapi ketika menggunakan binder maka diperlukan udara panas agar binder dapat membentuk lapisan dipermukaan kain. Situasi ini sesuai dengan penelitian yang telah dilakukan oleh Aracil et. al.…”

Pore size matching up: A novel insight into cotton textile aromatic finishing

“…Because there is no or weak affinity between micro‐/nanocapsules and textiles, most of the aromatic finishing approaches described above require a binder, which can ensure the micro‐/nanocapsules adhering in textiles to resist washing and rubbing . At present, while several researchers are focused on the effect of finishing methods and also types of binders on the carrying capability and durability of aromatic textiles finished with micro‐/nanocapsules, particle sizes of micro‐/nanocapsules and types of textile weaving parameters are also the key factors which can affect the carrying capability and durability of aromatic textiles.…”
