A novel nanocomposite sizing agent combining NH₂-MIL-53(Al) metal-organic frameworks (MOFs) with a water-soluble polysiloxane (POS) has been prepared to improve both the thermomechanical and amphiphobic properties of BFs. The composition mimics the main compositions of BFs to construct a topology, where the inorganic part of Al-MOFs is mainly responsible for enhancing roughness and heat-resistance and the organic part of POS is needed to mediate chemical heterogeneity and film forming property. The sized BFs exhibit significantly enhanced mechanical properties compared to the naked BFs, with the breaking force and elongation increasing from 8.04 cN to 21.1 cN and from 1.58 % to 2.64 % at room temperature, about 162.4 % and 67.1 %, respectively.

Alkoxide precursors were reacted in a water-based solution using HCl as the catalyst, and the resulting sols were deposited by rod coating to form optically transparent layers. The incorporation of polyvinyl alcohol (PVA) was critical, producing a homogeneous, crack-free coating that improved the oxygen barrier by a factor of 12.

Tests on the physical and chemical properties, rheological properties and printability of the inks have demonstrated excellent overall printability. Low-field nuclear magnetic resonance (LF-NMR) shows that the addition of DETA enhances the physical cross-linking of the ink, which can effectively limit the mobility of water molecules in the ink system, thus reducing the spreading of the ink on the fabric surface. The ink spreading process shows that DETA enhances the viscoelasticity of the ink and prolongs the infiltration time of the ink droplets on polyester fabrics, thus alleviating the problem of ink bleeding on fabrics and forming a deeper value of print colour depth. Printed fabrics using Y-0.1-1.2 and B-0.06-1.2 inks have excellent colour acquisition, print clarity and colour fastness.
