The invention relates to biomass-based degradable leather and a preparation process thereof, and belongs to the technical field of environment-friendly polymer composite materials. The leather is prepared from the following components: 30 to 60 parts of biodegradable polyester, 15 to 30 parts of surface modified natural fiber, 5 to 15 parts of castor oil-based silanization fatting agent, 3 to 10 parts of bio-based plasticizer, 5 to 20 parts of biomass filler, 1 to 5 parts of bio-based cross-linking agent, 0.5 to 3 parts of foaming agent, 0.5 to 2 parts of lubricating agent and 0 to 3 parts of functional additive. The preparation method is characterized in that a castor oil-based silanization fatting agent with a hydrolyzable siloxane group at the tail end is adopted to form covalent bond combination with fibers; constructing a three-dimensional network structure by using a citric acid-polyol bio-based cross-linking agent; and uniform micropores are formed through a pressure relief foaming process. The obtained product has excellent mechanical properties, soft and breathable hand feeling and complete biodegradability, and solves the problems of weak interface bonding and insufficient performance of the existing bio-based leather material.

This invention discloses a self-adjusting iridescent luminous roller blind fabric and its manufacturing method, comprising the following steps: S1 using polyethylene granules and phosphorescent powder as substrates, PE luminescent film material is melt-extruded; S2 using iridescent coating slurry to coat both sides of the PE luminescent film material to obtain iridescent luminescent film material; S3 using the iridescent luminescent film material as the core, and selecting bright polyester POY yarn for twisting and composite bonding to obtain iridescent luminescent composite yarn; S4 using low-elasticity polyester network yarn as warp yarn, and bright air-textured yarn, iridescent luminescent composite yarn, and polyester staple fiber yarn as weft yarn to weave iridescent luminescent fabric; S5 applying a roller blind fabric coating finish to the iridescent luminescent fabric to obtain the self-adjusting iridescent luminous roller blind fabric. The roller blind fabric obtained using this method not only has a long luminous time, better thermal stability, and a long luminous lifespan, but also exhibits adaptive adjustment according to changes in ambient light during luminescence, and possesses a special iridescent flashing effect.

This utility model relates to the field of clock pointer technology, specifically disclosing a novel round-bottomed clock pointer, including a pointer indicator for indicating the time on the clock; a disc for mounting on the clock so that the pointer indicator indicates the time; and a mounting mechanism for mounting the disc and the pointer indicator on the clock, the mounting mechanism being located on the disc. The novel round-bottomed clock pointer of this utility model features an ingeniously designed mounting mechanism located on the disc, comprising a circular hole and a magnetic sleeve. A magnetic strip is provided on the inner wall of the circular hole. During installation, simply insert the magnetic sleeve into the circular hole. Because the outer wall of the magnetic sleeve and the inner wall of the circular hole are slidably fitted, the insertion process is ensured to be smooth and stable, avoiding shaking and offset during installation. This achieves convenient installation, accurate time indication, and a unique appearance and functional display, providing users with a higher quality and more personalized clock usage experience.

This utility model discloses a double-layer fabric structure with a multi-jacquard hooking process, including a double-layer fabric body composed of an upper layer and a lower layer. The surface of the double-layer fabric body is provided with a jacquard area, which can be of any shape. The upper and lower layers are connected in the jacquard area by a hooking process. Specifically, the upper and lower layers are connected by hooking the warp yarns. In the jacquard area, the lower warp yarns pass through the upper fabric and interweave with the upper weft yarns to form hook points. The density of hook points is greater at the edges and key parts of the jacquard pattern than in non-jacquard areas. The distribution of these hook points forms a down-filling channel. The down-filling channel formed by the hook point distribution of this utility model allows for subsequent down-filling processing, giving the fabric new functions such as warmth and softness, expanding the application scenarios of double-layer fabrics. The jacquard pattern has a distinct three-dimensional effect, making it more visually appealing than traditional double-layer fabrics.

The invention discloses a seed production method and application of a terminal paternal line for producing tile grey chickens with crested characters, and belongs to the technical field of poultry genetic breeding and propagation. According to the method, the grey character of the tile grey chicken and the appearance character of the crested head of the Taihe black-bone chicken are successfully combined for the first time, high-quality gene resources of the tile grey chicken and the Taihe black-bone chicken are effectively integrated, the genetic advantages of local varieties are exerted, and a feasible path is provided for innovative utilization of local poultry varieties; by utilizing a molecular marker-assisted breeding mode, the genetic stability of target traits is directionally enhanced, the breeding period is shortened, and the breeding efficiency is remarkably improved; a new poultry strain with white feather is used as a terminal paternal line to be hybridized with other colored feather lines, so that commercial generation tile grey chickens with gray feather can be produced, and the difficulty of breeding the same commercial line by using commercial generation broiler chickens and the difficulty and cost of reverse imitation are greatly increased. The method has wide application prospects in the aspects of characteristic poultry breeding, ornamental poultry breeding and high-quality poultry breeding.
