Abstract

"PROCESSO PARA FORMAR UM REVESTIMENTO DE POLIFLUOROCARBONO EM UM FIO DE CORTE DE L‰MINA DE BARBEAR, E, FIO DE CORTE DE L‰MINA DE BARBEAR APERFEIçOADO". A presente invenção diz respeito a fios de corte de lâminas de barbear, que apresentam um aperfeiçoamento na primeira barba. Os fios de corte das lâminas de barbear convencionais apresentam, surpreendentemente elevadas intensidades de corte iniciais. As lâminas de barbear produzidas de acordo com o presente processo apresentam significativamente menor intensidade de corte inicial, que se correlaciona com um primeiro barbear mais confortável. As lâminas aperfeiçoadas de acordo com a presente invenção envolvem o tratamento dos fios de corte de lâminas de barbear convencionais, tendo um revestimento de polifluorocarbono aderente, com um solvente, para remover parcialmente alguma parte do revestimento. Solventes preferidos incluem os perfluoroalcanos, os perfluorocicloalcanos, os perfluoropoliéteres tendo uma temperatura crítica ou ponto de ebulição acima da temperatura de dissolução para o polifluorocarbono no solvente. A presente invenção também diz respeito ao processo de produção destes fios de corte de lâminas de barbear.
