Provided is an eccentric core-sheath composite false-twisted yarn, in which, in a cross section of a composite fiber composed of two polymers that are a component A and a component B, the component A is completely covered with the component B, a ratio S/D of a minimum thickness S of a thickness of the component B covering the component A to a fiber diameter D is 0.01 to 0.1, a peripheral length of a fiber at a portion where a thickness is 1.05 times or less the minimum thickness S is or more of a peripheral length of the entire fiber, a difference in modification degree between the single yarns is 0.2 or more, and a crimping rate is 30% or more.

Disclosed is a method for making a polymer or copolymer aerogel product by forming an aerogel polymer or copolymer solution in the presence of a polymer or copolymer catalyst and solvent therefor. The aerogel polymer or copolymer solution is drained onto a spinning disk or cup. The solvent is removed under aerogel forming conditions to produce the aerogel fiber web or yarn product.

The invention relates to a high-strength composite suture. More specifically, the high-strength composite suture comprises an integrated monofilament into the textile to provide for improved structural support when forming new shapes from one or more portions of the composite textile. The composite textile comprises a multifilament suture including UHWMPE material, and a monofilament strand that includes synthetic polymers such as Nylon and Polypropylene.

The invention relates to a method and apparatus for manufacturing carpets with an antique appearance using an automated weaving machine. The system integrates advanced control of warp tension, specialized pile yarn, and a unique reed and lancet assembly to replicate the randomized wear patterns, variable pile heights, and textural intricacies characteristic of aged carpets. A blend of synthetic and natural fibers undergoes a proprietary crimping, spinning, and two-stage dyeing process, producing multicolored yarn with pseudo-random shrinkage properties. Warp threads are precisely positioned using weighted beams and tiered lancets, enabling the creation of areas with zero and non-zero pile heights, separated by gradual transition zones. The resulting carpets exhibit high aesthetic authenticity and structural durability. A chi-squared statistical process ensures the randomness of worn patterns, optimizing the antique effect. The invention provides a scalable and efficient solution for producing affordable carpets that closely mimic the look and feel of genuine antiques.

The present application discloses a damping mesh, including at least two first wires and at least two second wires. The first wires and the second wires are interlacedly weaved with each other. Each first wire includes a first circular wire with a circular cross-section and first protrusion portions formed by opposite sides of the first circular wire along the second direction extending outward. Each second wire includes a second circular wire with a circular cross-section and second protrusion portions formed by opposite sides of the second circular wire along the first direction extending outward. The two first protrusion portions located on a side of two adjacent first wires that are close to each other and the two second protrusion portions located on a side of two adjacent second wires that are close to each other together form a ventilation hole.

Self-adaptive fabrics for space applications are provided. In one aspect, a fabric for use in space includes a structural fabric and a plurality of synthetic fibers woven into a self-adaptive fabric.
