The present invention provides compositions comprising aligned fibers of electrospun PNIPAAm and poly (?-caprolactone) (PCL) (denoted PNIPAAm/PCL fibers). The PNIPAAm/PCL compositions enable enhanced growth and detachment of intact anisotropic cell sheets. The compositions do not require chemical modification or resource-intensive techniques, thus saving time and expense, and have the potential to generate tissue-specific, aligned cell sheets for transplant studies.

Soft surface articles may be treated during manufacture with treatment articles loaded with treatment chemicals while drying the soft surface articles. This eliminates a step of adding the treatment chemicals to a water bath containing the treatment chemicals. Eliminating this step reduces the amount of water used in the manufacture of the soft surface articles and also removes the requirement of having to process a vat of waste water.
