DRY METHODS FOR PRODUCING A NONWOVEN FABRIC FROM TANNED LEATHER WASTE
20240191408 · 2024-06-13 ·

A dry method for manufacturing a non-woven fabric from tanned leather scraps involves providing tanned leather scraps in the form of compact material, subjecting the tanned leather scraps to opening to tear the compact material into fiber, and subjecting the torn material to carding. Textile fibers are added during carding to obtain a web of mixed fibers, the textile fibers including wool fibers. The dry method further involves subjecting the web of mixed fibers to needling to obtain a felt. The web of mixed fibers is free of impregnating agents and includes a leather fiber component composed of tanned leather fibers having a diameter of between 4 ?m and 70 ?m and a length of between 4 mm and 20 mm. The leather fiber component is comprised in a weight percentage greater than or equal to 50% of a total weight of the fibers in the web of mixed fibers.

Natural wool pile fabric and method for making wool pile fabric

A method of making a deep pile fabric that closely resembles natural sheepskin fleece. The method includes forming a length of pile fabric having fibers on one side and a scrim on an opposing side, where at least a portion of the fibers are natural wool fibers, and finishing the pile fabric as natural sheepskin by polishing the fiber side of the pile fabric, including guiding the length of pile fabric over at least two polishing rolls, where the two polishing rolls rotate in opposite directions.

Method of producing fabric for airbag
10259421 · 2019-04-16 · ·

The purpose of the present invention is to provide a method of producing a fabric for an air bag that, during high-pressure deployment at high speed, maintains low air permeability as an air bag and is capable of maintaining the low air permeability even after exposure to heat. This method of producing a fabric for an air bag comprises the steps of: 1) weaving with high tension warp threads at 0.20 cN/dtex to 0.65 cN/dtex in a water jet loom, 2) carrying out a washing treatment step at 80 C. or lower or not carrying out a washing step, 3) drying at a temperature of 110 C. or lower, and 4) carrying out calendering processing.

Woven preform, composite, and method of making thereof

A three dimensional woven preform, a fiber reinforced composite incorporating the preform, and methods of making thereof are disclosed. The woven preform includes one or more layers of a warp steered fabric. A portion of the warp steered fabric is compressed into a mold to form an upstanding leg. The preform includes the upstanding leg and a joggle in a body portion. The body portion and upstanding leg are integrally woven so there is continuous fiber across the preform. A portion of the warp steered fabric includes stretch broken carbon fibers in the warp direction, and another portion includes conventional carbon fibers. The warp steered fabric can be woven on a loom equipped with a differential take-up mechanism. The warp steered fabric can be a single or multilayer fabric. The preform or the composite can be a portion of an aircraft window frame.
