ELECTROSTATIC FILAMENT DISPERSAL FOR CMC APPLICATIONS

A method of preparing a woven fabric material for use in a ceramic matrix composite includes passing a desized woven fabric tape having a first inter-filament spacing through a dispersal module configured to transform the desized woven fabric tape into a dispersed woven fabric tape having a second inter-filament spacing greater than the first inter-filament spacing. The dispersal module includes a first charging element with a charged surface and disposed to apply an electric charge to the desized woven fabric tape. The method further includes applying a polymer binder to the dispersed woven fabric tape to create a stabilized woven fabric tape having the second inter-filament spacing.

NON-WOVEN TEXTILE FROM UPCYCLED FRUIT AND VEGETABLE WASTE
20230053954 · 2023-02-23 ·

The present invention discloses a hydrophobic non-woven textile and the method of production thereof, the method for production comprising the steps of providing a fruit or vegetable pomace, comminuting the pomace, mixing the disrupted pomace with a density-modifying agent, dehydrating the disrupted pomace, distributing the water reduced pomace on a surface, drying the distributed water reduced pomace, and coating the non-woven textile with a hydrophobic polymer to provide the hydrophobic non-woven textile.

ADSORBENT MATERIAL
20220362738 · 2022-11-17 ·

A flexible material is disclosed comprising a flexible substrate, a sorbent comprising zirconium hydroxide and a binder, wherein the solids weight ratio of the binder to the zirconium hydroxide is in the range 1:1 to 1:120. Also disclosed is a process for production of a fabric, comprising: providing a flexible material, providing at least one sorbent dispersion comprising zirconium hydroxide and a binder, applying the sorbent dispersion to the flexible material to produce a treated flexible material, squeezing the treated flexible material under pressure, and passing the pressed treated flexible material through a stenter.

ANTI-PILLING MERINO WOOL FABRIC, GARMENTS COMPRISING THEREOF, AND METHOD OF FABRICATION THEREOF

The present invention provides an anti-pilling wool fabric with a coating having pilling resistance and resistance to fiber loss from fabric surface. The coating is formed by a coating formulation including at least two diisocyanates, at least two catalyst, a water dispersing agent, a buffer and water, which provides a polycarbodiimide crosslinker reactive to the relative less reactive groups on polypeptide of the wool fabric and promotes crosslinking between polypeptides of the wool fabric under relatively mild processing conditions so as to enhance mechanical strength of the wool fabric whilst no significant effect of the original finish merino wool fabric and/or garment and fiber loss from fabric surface are observed, compared to conventional treatment methods on wool fabric. A corresponding coating formulation and method of fabricating the anti-pilling wool fabric are also provided. The present invention is applicable to finished wool fabric which fibers are already with colorant(s), and/or dye(s), and/or reactive dye(s).

FRUIT EXTRACT LEATHER AND PREPARATION METHOD THEREOF
20230088764 · 2023-03-23 ·

This application provides a fruit extract leather. The fruit extract leather includes a prepolymer material A, a prepolymer material B, and a base fabric. The prepolymer material A includes a fruit powder, and the fruit powder is obtained by grinding a remaining residue material obtained after fruit peels and/or fruit kernels are extracted. This application further provides a method for preparing the fruit extract leather. According to the fruit extract leather and the preparation method thereof provided in this application, polyester and other components in leather are substituted, fruit peels and/or fruit kernels are recycled, and waste and environmental pollution are reduced.
