A method of making a nonwoven fiber web comprises: providing a melt-blown nonwoven fiber web comprising bonded primary fibers having an average fiber diameter of 2 to 100 microns, wherein the primary fibers comprise a copolymer comprising divalent hydroxyethylene monomer units and divalent dihydroxybutylene monomer units; opening at least a portion of the melt-blown nonwoven fiber web to provide loose primary fibers; combining the loose primary fibers with secondary fibers; and forming a secondary nonwoven fiber web comprising the primary fibers and secondary fibers. A fiber web preparable according to the method and a multicomponent fiber including a first phase comprising a copolymer comprising divalent hydroxyethylene monomer units and divalent dihydroxybutylene monomer units and a second phase comprising a non-biodegradable polymer.

The present invention relates to a starch composition comprising a starch and a vinyl alcohol-based polymer, wherein the starch has an amylopectin ratio of 70% or more, the vinyl alcohol-based polymer has a degree of saponification of 96 mol % or less, and based on a total mass of the starch and the vinyl alcohol-based polymer, a ratio of the starch is 40 to 90% by mass and a ratio of the vinyl alcohol-based polymer is 10 to 60% by mass.

Electrospun Polyvinyl Alcohol (PVA)/Inulin composite nanofibers (CNFs) are provided using electrospinning technique and tested for their prebiotic and antibacterial activities. The PVA/Inulin electrospun CNFs were tested for prebiotic activity with Lactobacillus sp. and for antibacterial activity against both Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus). A number of electrospinning parameters such as solution concentration, PVA: Inulin mixing ratio, solution flow rate and applied voltage were carefully varied and the best PVA/Inulin electrospun CNFs (bead free) were selected for prebiotic and antibacterial tests. The concentration of the composite solution varied between 14-20%, the flow rate ranged between 0.005-0.5 mL/min and the applied voltage used ranged between 15-20 Kv. The structural properties and morphology of the PVA/Inulin electrospun CNFs were fully characterized by Fourier Transform Infrared Spectroscopy (FT-IR) and scanning electron microscopy (SEM).

A plurality of fibers or one-dimensional, two-dimensional, or three-dimensional fibrous structures are provided, having fibers from a first raw fiber material. The first raw fiber material contains unsubstituted or partially substituted polyvinyl alcohol and/or unsubstituted or partially substituted polyvinyl alcohol copolymer. The fibers can be crosslinked by tempering the fibers or fibrous structures, with the result that the fibers or the fibrous structure are configured to be gel, in particular hydrogel, fibers or fibrous structures and have excellent stability.
