For intense handling of acids and other chemicals, special\r\nprotective lab coats with rubber or vinyl apron or chemical-resistant overalls are used. The purpose of this\r\npaper is to investigate the possibility to protect lab coats from acid damages by finishing them with\r\ncommercially available hydrophobization chemicals.\r\nDesign/methodology/approach – Two commercial hydrophobic sprays were applied on cotton, polyamide\r\nand polyester lab coat materials. Contact and roll-off angles were compared with the untreated textile fabrics\r\nbefore typical laboratory acids were applied on the fabrics. Finally, antibacterial properties of the finished\r\ntextiles were examined.\r\nFindings – Spray 1 resulted in significantly increased hydrophobicity, while spray 2 did not have any\r\ninfluence on the results. With spray 1, the originally hydrophobic fabrics became more hydrophobic, and even\r\nthe originally strongly hydrophilic fabrics showed large contact angles of 130–140°. Roll-off angles were\r\nsignificantly reduced from 40 to 50° ( for the hydrophobic fabrics) or even 90° (in case of hydrophilic fabrics)\r\nto approximately 15–25°. Correspondingly, spray 1 showed an increase of the acid resistance of the finished\r\ntextile fabrics of up to 30 min for the originally hydrophobic fabrics and up to 20 min for the originally\r\nhydrophilic ones, with only one polyester fabric showing no acid resistance at all, while spray 2 led to\r\nincreased antibacterial properties.\r\nPractical implications – While spray 1 can support laboratory safety by increasing the time until acids\r\npenetrate through a lab coat, spray 2 can support sterile work in a biological laboratory.\r\nOriginality/value – To the best of the authors’ knowledge, increasing the acid resistance as well as the\r\nantibacterial properties of lab coats with easily accessible sprays has not been eported before in\r\nthe scientific literature\r\n","lang":"eng"}],"status":"public","author":[{"last_name":"Hilenberg","full_name":"Hilenberg, E.","first_name":"E."},{"first_name":"E.","last_name":"Taskin","full_name":"Taskin, E."},{"id":"223776","orcid_put_code_url":"https://api.orcid.org/v2.0/0000-0003-0695-3905/work/172528865","first_name":"Andrea","full_name":"Ehrmann, Andrea","orcid":"0000-0003-0695-3905","last_name":"Ehrmann"}],"citation":{"apa":"Hilenberg, E., Taskin, E., &#38; Ehrmann, A.
