Spunbond nonwoven laminate and method of making same

A spunbond nonwoven laminate has a stack of at least two and at most four spunbond nonwoven layers each formed by or consisting of crimped continuous filaments. A degree of crimping of the filaments in each of the spunbond nonwoven layers is different from a degree of crimping in each of the other spunbond nonwoven layers and each of the crimped filaments of the spunbond nonwoven layers has a crimp with at least two loops per centimeter of length. The crimped filaments of the spunbond nonwoven layers are multicomponent filaments each having at least one first plastic component and at least one second plastic component with each of the plastic components being present in the respective filament in a proportion of at least 10 wt %.

Microfiber-containing nonwoven fabrics

Nonwoven fabrics including (i) continuous fibers and (ii) a blend of staple fibers comprising polyester staple fibers, bicomponent staple fibers, microfiber staple fibers, and wettable staple fibers, in which the continuous fibers are mechanically entangled with the blend of staple fibers. The continuous fibers and the blend of staple fibers may be mechanically entangled via a hydroentangling process.

METHOD FOR PRODUCING A CARRIER LAYER WITH A HYDROPHILIC POLYMERIC NANOCOATING

The invention relates to a method for producing a carrier layer with a hydrophilic polymeric nanocoating wherein a polymeric carrier layer is produced with filaments of polymer material(s). Further the hydrophilic polymer nanocoating is applied by means of a low pressure plasma polymerization process using organic precursor monomers onto the polymeric carrier layer and/or composite membrane. Additionally, the invention relates to a carrier layer with a polymeric hydrophilic nanocoating.

METHOD OF MAKING A SPUNBOND NONWOVEN LAMINATE

A spunbond nonwoven laminate has a plurality of stacked spunbond nonwoven layers, namely at least two and at most four spunbond nonwoven layers that have crimped continuous filaments or consist of crimped continuous filaments. The degree of crimping of the filaments is different in each of these spunbond nonwoven layers, and each of the crimped filaments of the spunbond nonwoven layers has a crimp with at least two, preferably at least three, and more preferably with at least four loops per centimeter of length. The crimped filaments of the spunbond nonwoven layers are multicomponent filaments, particularly bicomponent filaments, with a first plastic component and a second plastic component present in the respective filament in a proportion of at least 10 wt %.

RECYCLABLE, ASYMMETRICAL-FACED COMPOSITE NONWOVEN TEXTILE HAVING VARIED DENIER
20220136157 · 2022-05-05 ·

Aspects herein are directed to a recyclable, asymmetrical-faced composite nonwoven textile suitable for use in apparel and other articles and methods of making the same. In example aspects, the asymmetrical-faced composite nonwoven textile includes a first face formed, at least in part from a first entangled web of fibers and an opposite second face formed, at least in part from a second entangled web of fibers. When incorporated into an article of apparel, the first face forms an outer-facing surface of the article of apparel, and the second face forms an inner-facing surface of the article of apparel. The first face includes features making it suitable to form the outer-facing surface such as resistance to abrasion, and the second face includes features making it suitable to form an inner-facing surface such as a soft hand.

Electrospun PNIPAAm/PCL Fiber Mats for Aligned Cell Sheets
20210363675 · 2021-11-25 ·

The present invention provides compositions comprising aligned fibers of electrospun PNIPAAm and poly (ϵ-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.
