The present disclosure provides a polyamide 5X staple fiber, a preparation method and use thereof. The polyamide 5X staple fiber has a denier of 8.0-30.0D, a breaking strength of 2.0-6.0 cN/dtex, and an elongation at break of 30-100%. The polyamide 5X staple fiber has good mechanical properties and softness, and a blended wool yarn for manufacturing carpets with good mechanical properties, dyeability, and wear resistance can be obtained by using the polyamide 5X staple fiber.

Wool fabrics are disclosed that have improved stretch properties. The wool fabrics can be used in numerous and diverse applications, such as to make uniforms. The fabric can be designed to have greater than 15%, such as greater than about 20% stretch in one or more directions, such as in the fill direction. In one aspect, longer wool fibers are used in the fabric in order to increase durability.

The invention relates to non-woven protein fibers and to methods for forming and producing the same. In certain embodiments, the invention provides a method of processing a protein comprising dissolving a protein in a solution, optionally removing any insoluble materials from the solution, and spraying the solution under an applied pressure. In other embodiments, the protein can be derived from a range of sources, including but not limited to arthropod silks, animal keratin (e.g. hair and wool), tissue elastin, collagen, resilin, and plant protein. In certain embodiments, the methods of the invention are an alternative to electrospinning methods known in the art.

A manufactured shearling material comprises a leather layer and a knitted wool layer laminated together. The leather layer may be made by grinding up waste/scrap leather and adhering it to a backing, and giving texture (or texturizing) a surface to give the surface a particular feel (e.g., a suede feel). The scrap leather may be from various animals, including cows, sheep, etc. The knitted wool layer may comprise recycled wool clippings organized together to simulate the fur surface of natural shearling, and the wool clippings may be combined with one or more additional materials (e.g., fur, cotton, polyester, Tencel, silk, etc.) at various blends (e.g., 80/20 blend of wool and Tencel) to control the feel, aesthetics, and/or functionality, etc. of the knitted wool layer. Furs, hair, or other materials other may be utilized instead of the recycled wool clippings. An additional layer may be provided on top of the leather, with such additional layer being a synthetic recycled fabric.

The present invention relates to a process for producing dyed mixed fibres (D-MF), dyed mixed fibre yarns (D-MY) and/or dyed mixed fibre textile fabrics (D-MT) in which mixed fibres (MF), mixed fibre yarns (MY) and/or mixed fibre textile fabrics (MT) comprising at least one polyester fibre (PF) and at least one further fibre (FF) are simultaneously contacted with at least two different dyes (D1) and (D2) at a temperature T.sub.D<130° C. The at least one polyester fibre (PF) comprises 80 to 99.5% by weight of at least one terephthalate polyester (A), 0.5 to 20% by weight of at least one aliphatic-aromatic polyester (B) and 0 to 5% by weight of at least one additive (C), wherein the % by weight are based in each case on the total weight of components (A), (B) and optionally (C). Moreover, the present invention relates to the dyed mixed fibres (D-MF), the dyed mixed fibre yarns (D-MY) and/or the dyed mixed fibre textile fabrics (D-MT) obtained by this process.

The fabric can be designed to have greater than 15%, such as greater than about 20% stretch in one or more directions, such as in the fill direction. In one aspect, longer wool fibers are used in the fabric in order to increase durability.

A filamentary core for an elastic composite yarn, particularly for an elastic textile composite yarn, comprising at least two elastic performance filaments, wherein each of the at least two elastic performance filaments is capable of being stretched at least about 2 times its package length and has at least 90% up to 100% elastic recovery after having being released from a stretching 2 times its package length.

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).

A heat-generating fabric contains an modacrylic fiber A and an animal hair fiber. The modacrylic fiber A contains an infrared absorber inside of the fiber, in an amount of 1 to 30% by weight with respect to the total weight of the modacrylic fiber, and the fabric has a heat-shielding rate of less than 40% as measured according to JIS L 1951:2019. The heat-generating fabric contains a first yarn and a second yarn whose fiber composition is different from that of the first yarn. The first yarn may contain the modacrylic fiber A, and the second yarn may contain the animal hair fiber. Accordingly, it is possible to provide a fabric with good heat-generating performance and durability, and a textile product containing the fabric.

A method for processing a waste fabric containing polyester and wool fibers includes the following steps. The method is to treat the waste fabric with an acid catalyst aqueous solution at 160° C. to 170° C. The wool fibers are degraded and completely separated from the polyester fibers in a treatment process. Afterwards, the polyester fibers are recycled.
