摘要： A method of laundering a soiled stitchbonded nonwoven towel, to provide hygienically-clean, odor-free towels having a non-durable soil release polymer agents on the fabrics and stitching. The method has a step of washing soiled stitchbonded nonwoven towels in a first aqueous wash solution formed from a first wash composition comprising a surfactant, a builder, an alkalinity source, and a soil release polymer, at a first alkaline pH, and at a first wash temperature sufficient to remove soil on the towels without redeposition of the soil back onto the towels or into the laundry machine once the residual wash solution is drained. The method also has a step of treating the washed towels in a treatment solution formed from a post-wash composition comprising a soil release polymer agent, at a temperature and pH sufficient to aid in exhausting soil release polymer from the treatment solution and onto the towels or fabrics.

摘要： A stitchbonded washable towel made from a stitchbonded fabric having a cellulosic nonwoven sheet of cellulosic fibers, and an integrated nonwoven sheet of an outer sublayer of wood pulp fibers, and an inner layer of textile fibers substantially entangled with the wood pulp fibers, and confronting the cellulosic nonwoven sheet of cellulosic fibers. The stitchbonded fabric as uses a pattern of stitching yarns that fixes the cellulosic nonwoven sheet to the integrated nonwoven sheet. A post-treatment of the stitchbonded fabric in a heated aqueous solution containing soil release polymer gathers the fabric into the towel, and provides stain and soil re-deposition resistance.
