Abstract

Purpose

The present research aims to manage the formulations of pigment-based inks containing aminopropyl/vinyl/silsesquioxane (APSV) as a pigment binding agent for inkjet printing of polyester as a commercial trial for the printing of polyester as a single-step process.

Design/methodology/approach

The proposed formulations incorporated APSV by using the mini-emulsion technique at a low relieving temperature under the thermal initiation or UV radiation of vinyl-terminated groups in APSV. In this study, the storage stability of inks with regard to physical properties was broadly examined. Moreover, the color performance, including colorimetric data, color fixation and fastness properties of printed fabrics was evaluated.

Findings

The results indicated that the inks containing APSV were formulated and were stable in terms of particle size, dispersion stability, surface tension and viscosity over a period of one month and for four freeze/thaw cycles. APSV successfully fixed the pigment-based inkjet inks on polyester fabric and could achieve a significantly higher color performance and degree of fixation than the formulated inks without APSV.

Research limitations/implications

It could also fulfill all the physical properties of ink prerequisites over storing and eliminating all challenges in improving the performance and utilization of inkjet printing.

Practical implications

APSV can also be used as a pigment binding agent to formulate inks for inkjet printing of polyester fabrics as the authors’ past examination for inkjet printing of polyester fabrics post-treated with APSV.

Social implications

This study eliminates the noteworthy challenges in formulating the pigment-based inks for textile applications by incorporation of a binder while keeping up the necessary viscosity profile for a specific print head.

Originality/value

This study addressed all the issues arising from the complex nature and very challenging requirements of inkjet inks.

Abstract

Purpose

The purpose of this study is to aim at: (1) investigating the vulnerabilities/obstacles that hinder refugees in hosting countries from obtaining quality and adequate education and (2) proposing a Framework for Action to transform these vulnerabilities into capacities.

Design/methodology/approach

Vulnerability and Capacity Assessment (VCA) was used for the purpose of this research. A survey strategy was adopted and data were collected using semi-structured interviews with refugee families. One hundred and twenty families were interviewed.

Findings

The study identified a number of vulnerabilities; including mainly unavailability of educational facilities; quality of the available education; social challenges and psychological needs. The findings revealed that there was a lack of comprehensive and strategic frameworks for mitigating refugee educational crises.

Practical implications

The lack of adequate and quality education for refugees in host countries is likely to increase illiteracy levels and subsequently trigger humanitarian and natural disasters on the long run. This research emphasizes the importance of developing comprehensive frameworks for quality and adequate refugee education.

Originality/value

To the author's knowledge, and after an extensive review of the existing literature, this is the first study to employ VCA to investigate the extent of the current refugee educational crisis in Jordan. VCA is more commonly used in the context of natural and environmental disasters threatening societies. Relevant authorities need to be aware of the significance of refugee education at individual, communal and national levels, as well as the significance of education to refugee well-being.
