The present disclosure relates to multi-layer composite articles including at least two nonwoven web layers. Each or the layers may be a spunbonded web, and each may include biodegradable materials. The multi-layered composites of the present disclosure are particularly well suited for air filtration, as they can combine a high dust holding capacity with sufficient strength, dimensional stability, and a relatively low pressure drop.

Nanofiber structures are provided as well as methods of use thereof and methods of making.

The present application relates to biodegradable and ecofriendly fabrics and methods for making the same. The fabrics are made from PLA fibers and/or yarns, and have one-way or two-way filtration characteristics and/or moisture management characteristics with controlled porosity and smooth or textured surface, the moisture management characteristics arise from a combined effect of material properties and fabric structure.

Disclosed is a method for preparing a fully-degradable non-woven fabric by spun-bonding, including: (S1) preparation of a poly(caprolactone-co-lactide acid) (P(CL-co-LA)); (S2) preparation of a copolymerized-modified poly(lactide acid) (PLA); and (S3) preparation of a full-degradable non-woven fabric using a spun-bond method. In this disclosure, the PLA is modified in gradient several times to prepare the full-degradable non-woven fabric in combination with an optimized spun-bonding method.

A label and related method of manufacture that includes a fabric made of yarn, in either cut individual singles or continuous ribbon format in any length. The yarn includes a fiber that has been recycled, that is recyclable, that is organic, that is biodegradable, and/or that can be derived from a material that is known to be environmentally friendly. The yarn, in one embodiment, may include a fiber defined as “high filament count” material, above the current industry standard of 24 filaments, being in the range of 72 to 96 to 144 filaments or higher per individual yarn, in any denier range of 30 denier to 150 denier thickness, in natural raw white, optical dyed white, or dyed colors. These yarns can be independent of each other.

The present invention relates to a fibrous 3-dimensional porous scaffold obtained by electro-spinning for tissue regeneration and a method for preparing the same.

An eco-friendly netting for growing and/or harvesting sod, plants, and/or any type of vegetation is disclosed herein. The eco-friendly netting includes a plurality of fibers arranged in a substantially non-woven configuration. Each of the plurality of fibers is formed from a substantially natural material, which may also be biodegradable. The eco-friendly netting may be preseeded. The eco-friendly netting may be treated or processed with anti-rot agents, degrading accelerators, degrading inhibitors, nutrients, fertilizers, pesticides, fungicides, algaecides, herbicides, water absorption/retention enhancers or any combination thereof. Methods of growing sod and harvesting sod, which utilize the eco-friendly netting, are also disclosed herein. In one or more embodiments, the eco-friendly netting may be treated or processed to increase or decrease its functional longevity.

Disclosed herein are bioerodible drug delivery devices including one or more active agents, and related methods. The devices are useful for administering a wide variety of agents over prolonged periods of time.

A machine and a method for producing biodegradable nonwoven textile comprising including seeds including a seed distributing machine unit, positioned in a cross-lapping portion of the nonwoven textile machine. The seed distributing machine unit includes at least one receptacle for seeds having a dispensing opening for regulated outlet of seeds onto a veil of biodegradable fibres. A needle punching portion is situated after the cross-lapping, seen in the direction of the biodegradable nonwoven textile production line of the machine, for needle-punching of the veil of biodegradable fibres.
