This disclosure relates generally to the preparation of eco-friendly engineered fabric, and more particularly to terry fabric and variations thereof. In one embodiment, a terry fabric is comprised of a soluble fiber blend, blended with cotton fibers, where the soluble fibers are dissolved in a caustic or enzyme solution to create highly porous yarns.

The present disclosure discloses a method for preparing a pure chitosan fiber, and relates to the technical field of preparation of chitosan. The method includes the following steps: S1, preparing an acetic acid solution; S2, preparing a chitosan stock solution; S3, treating a chitosan spinning solution; and S4, preparing a chitosan fiber. In step S3, a pretreatment machine includes a body; an driving mechanism is arranged in the body; a stirring mechanism is arranged in the driving mechanism; a scraping mechanism is arranged below the driving mechanism; a preliminary treatment mechanism is arranged at an inner upper side of the body; the driving mechanism penetrates through the preliminary treatment mechanism and is arranged in the body; a separation mechanism is arranged on a bottom of the body.

A synthetic fiber blend fabric is disclosed. The synthetic fiber blend fabric is a woven fabric that is made from blended yarns each obtained by mix spinning of three or more kinds of fibers including wool fibers, polyester fibers, and acrylic fibers, or is a woven fabric mainly consisting of the blended yarns. Each of the blended yarns contains the three or more kinds of fibers blended therein so as to be approximately uniformly distributed at a prescribed blending ratio along a longitudinal direction of the blended yarn. The blended yarn has a total content of the wool fibers, the polyester fibers, and the acrylic fibers of 90 mass % or more and 100 mass % or less. The acrylic fibers have a fineness of 0.5 dtex or more and 1.4 dtex or less.

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.

Sucker ring tooth (SRT) proteins called Suckerins were identified from the sucker tissue of three distantly related Decapodiformes species. These proteins assemble into silk-like beta-sheet reinforced materials. The use of suckerin proteins to produce fibres, films and tissue scaffolds is also described.

The present disclosure discloses a method for preparing a pure chitosan fiber, and relates to the technical field of preparation of chitosan. The method includes the following steps: S1, preparing an acetic acid solution; S2, preparing a chitosan stock solution; S3, treating a chitosan spinning solution; and S4, preparing a chitosan fiber. In step S3, a pretreatment machine includes a body; an driving mechanism is arranged in the body; a stirring mechanism is arranged in the driving mechanism; a scraping mechanism is arranged below the driving mechanism; a preliminary treatment mechanism is arranged at an inner upper side of the body; the driving mechanism penetrates through the preliminary treatment mechanism and is arranged in the body; a separation mechanism is arranged on a bottom of the body.

A composite fiber is provided, which includes a polymer fiber, doped zinc oxide particles dispersed in the polymer fiber or combined with the polymer fiber, and a fluorescent dye combined with the polymer fiber. The light emission wavelength of the doped zinc oxide particles and the light absorption wavelength of the fluorescent dye overlap. The above composite fiber can be manufactured as a yarn and woven into a textile.

A screw feeder includes: a case that includes a material putting-in portion through which a fluff material is put in and a material putting-out portion through which the fluff material is put out below the material putting-in portion; and a screw that includes a rotational shaft and a blade portion, the rotational shaft being provided rotatably inside the case, the blade portion being spirally mounted on the rotational shaft; wherein the screw is rotated with repeated alternation of a slope-down direction in which the blade portion slopes downward spirally in a vertical direction and a slope-up direction in which the blade portion slopes upward spirally in the vertical direction.

An article of apparel including insulation material is discussed. The insulation material includes an insulating layer formed of waterfowl fibers and synthetic fibers. The waterfowl fibers are present in an amount of at least 20% by weight of the insulating layer. The insulating layer is generally free of waterfowl plumage.

Provided herein are mycelium materials and methods for production thereof. In some embodiments, a mycelium material includes: a mycelium material including one or more disrupted fibers, wherein the one or more disrupted fibers is oriented in a z-direction and/or a bonding agent may be combined with the mycelium material. Methods of producing a mycelium material are also provided.
