There are provided a towel cloth having a favorable uprightness of a pile, having a soft and bulky texture, and having a water absorbency in combination, and a manufacturing method thereof. The towel cloth is configured such that a warp pile yarn is engaged in a warp ground yarn and a weft ground yarn. The warp pile yarn is a siro spun yarn 19, and is a nontwisted or low twisted spun yarn applied with secondary twisting in the opposite direction to the primary twisting direction of a plurality of rovings 12a and 12b, namely, the untwisting direction. The twisting habit of primary twisting and migration of primary twisting cause entanglement between fibers. In addition, each fiber is a nontwisted yarn or a low twisted yarn, and hence each constituent fiber is present in a free state. This results in a pile yarn with a favorable uprightness and a soft and bulky texture.

The present invention relates to a light safety shoe (1), comprising:an upper (2); a sole (3) made by means of injection molding directly onto said upper (2); a safety toecap (4) placed at the toe of the shoe (1);a anti-puncture sheet (9) housed in said sole (3);a functional insert (7) placed within said sole (3), below said anti-puncture sheet (9). According to the invention, the light safety shoe (1) has, with reference to a European size 42, a weight lower or equal to 400 grams.

An artificial turf fiber comprising a polymer material and a traction control agent disposed within the polymer, wherein the traction control agent (404) is a grafted polymer (404) comprising a slip agent (302) grafted on a backbone (304) of the grafted polymer (404).

A nonreciprocal device is described. It includes a housing, a waveguide layer and at least one layer of magnetic nanofiber composite. The magnetic nanofiber composite layer is made up of a polymer base layer, a dielectric matrix comprising magnetic nanofibers. The nanofibers have a high aspect ratio and wherein said dielectric matrix is embedded in the polymer base layer.

A high-power bidirectional-driven bionic muscle fiber as well as a preparation method and use thereof are provided. The bionic muscle fiber includes a matrix fiber and an object material layer coating the matrix fiber, where the matrix material is capable of emitting heat after electrification, and the object material layer includes a liquid crystal elastomer (LCE); the bionic muscle fiber is excessively twisted to form a helical barrel-like structure. The bionic muscle fiber provided by the present application improves the mechanical property of the LCE, shows large work capability and drive quantity, and has an realize rapid response and work at high frequency. The contraction of the fiber can be controlled by changing voltage. Furthermore, the bionic muscle fiber exhibits a bidirectional driving feature that can recover without stress. In addition, the cyclic work of the fiber is greater than zero.

A magnetic response fiber material and a preparation method and an application thereof are provided, which relates to the field of oil-water separation materials. The preparation method includes: mixing a fiber-forming polymer, a primary solvent, a secondary solvent and magnetic nanoparticles to form a uniform spinning solution, where the fiber-forming polymer includes at least one of polyethylene, polypropylene and polymethylpentene; spinning the spinning solution by a spinning process to obtain the magnetic response fiber material. The prepared magnetic response fiber material has the advantages of high oil absorption speed, high oil absorption capacity and high separation efficiency. Magnetic nanoparticles have a high load, which can not only be driven by magnetic force to absorb oil floating on water surface, but also be driven to an underwater oil pollution position to absorb oil, and can be applied to water purification in oil-polluted areas that cannot be reached by manual processing.
