| 摘要 |
A particulate built nonionic synthetic organic detergent composition, useful for washing synthetic organic polymeric fibrous materials, such as polyesters and polyester-cotton blends, and imparting soil release properties to them, includes nonionic synthetic organic detergent, alkaline builder or mixture of builders for such detergent, a soil releasing copolymer of polyethylene terephthalate and polyoxyethylene terephthalate, and polyvinyl pyrrolidone (PVP). The PVP and the soil releasing polymer may be applied to base beads of builder salt(s) as a spray, in nonionic detergent. Alternatively, the PVP may be present as a coating on particles of the soil releasing polymer, which are blended with base builder beads onto which liquid state nonionic detergent has previously been sprayed and in which such spray has been absorbed. |
