FIELD: process engineering.
SUBSTANCE: set of invention relates to production of water-soluble film from nonwoven web, to film thus made, single-portion article including the bag formed from this film and to process of web article processing with step exploiting said water-soluble film. Production of water-soluble film consists in provision of nonwoven web including multiple filaments with filament-forming material soluble in polar solvent and conversion of nonwoven web into film. Note here that water-soluble film comprises one or more active agents for care of fabrics. Processing of fabric consists in pretreatment of spots on fabric article prior to its washing. Then, flushing solution is made by bringing water-soluble film in contact with water and fabric article in contact with water. Thereafter, fabric article is brought in contact with water-soluble film in drier to dry said article in the presence with water-soluble film in drier.
EFFECT: production of water-soluble film at high forming rates.
