After World War II, he emigrated to Chile where his brother Marcos had emigrated before the war. There with his brothers and brothers-in-law he founded the "Pollak Hnos." textile company. In 1960, Pinhas Sapir, then Israel's Minister of Industry, invited Pollak to make aliyah and to establish a textile plant in Kiryat Gat. The Pollak's new company, Polgat, grew into the largest textile, clothing and knitwear company in Israel. It eventually became a public corporation whose shares were traded on the Tel AvivStock Exchange. In 1970, the Pollaks founded Bagir, a men's division for suits and jackets.
