PAPER HAVING GOOD ABSORBENCY AND ALKALI RESISTANCE |
摘要 |
Fibrous paper webs of high water absorbency and improved alkaline wet tensile strength are obtained by treating the fibers prior to web formation or subsequent to web formation with aqueous solutions of a water-soluble thermosetting reaction product of a polyamide and an epichlorohydrin, a water-soluble nonviscose film-forming material such as hydroxy ethyl cellulose and a water-soluble polyethylene imine. The resultant absorbent sheet material maintains its absorbency upon aging, exhibits high wet caustic strength and can be used in the manufacture of tea bags or food casings. |
