I’m planning to investigate Textile Coatings for Home textiles. I read about various methods for Coatings. I want to impart functionality by coatings, such as Anti UV and Anti Static together, or antibacterial and self cleaning etc. I would like some advice about recommended techniques. I’m really looking to find out what you’d consider to be the most efficient method as cost and time are limiting factors.

The combinations you mentioned can be obtained by sol-gel coatings, using chemical nano-technology. Combining different functionalities is the big advantages of such sol-gel treatments, either with or without special particles inside.
The disadvantage is the often quite low abrasion resistance, washing resistance etc. We have made a project combining sol-gel treatment with excimer laser pre- and after-treatment, leading to increased washing resistance. But you will see yourself how resistant your coating is on your specific textile material, and whether the durability has to be increased.
One more comment about the sol-gel coating - after (for instance) antimicrobial treatment with silver nanoparticles in combination with organic-inorganic binder knits made of pure cellulose fibres, cellulose and synthetic PA and PES fibres blends, and pure PES fibres demonstrated different antimicrobial activity against bacteria (see: Mickevičienė, Agnė; Mikučionienė, Daiva; Ragelienė, Lina. Influence of raw composition of plain plated knits on their antimicrobial characteristics // Fibres and textiles in Eastern Europe. Lodz : Institute of Chemical Fibres. ISSN 1230-3666. 2014, vol. 22, no. 5 (107), p. 59-64.).
I would say to apply nano TiO2 along with citric acid and sodium hypophosphite and silicone softener.
