Description

Technical Field

[0001] This utility model relates to a temperature-regulating wool blended yarn, belonging to the technical field of wool blended yarn. Background Technology

[0002] With societal progress and rising living standards, people have higher demands for ready-made clothing worn close to the skin. For the textile industry, in this increasingly competitive market, to avoid being eliminated, it is essential to utilize new raw materials and engage in innovative research and development to enhance the technological content and added value of products, thereby meeting the personalized, fashionable, and functional needs of consumers.

[0003] Phase change temperature-regulating fiber blended yarn refers to a high-tech fiber blended yarn obtained by blending phase change temperature-regulating fibers with other types of yarn, which can respond to changes in external temperature. Fabrics made from this blended yarn can undergo a reversible phase change reaction according to temperature changes, thereby improving the comfort of clothing. When the temperature rises, it absorbs and stores heat, and the phase change substance changes from a solid to a liquid state. When the temperature drops, it releases the stored heat, and the phase change substance changes from a liquid to a solid state. Through the heat absorption and release process, the temperature around the fiber is maintained at a constant level to a certain extent. This property is not possessed by natural fibers and ordinary chemical fibers, and it is expected to bring new changes to people's future lives.

[0004] Wool blended yarns are typically used in thermal fabrics, but the temperature difference between indoors and outdoors is significant. Therefore, the problem to be solved is how to make the fabrics made from wool blended yarns have a temperature-regulating effect, i.e., to prepare a wool blended yarn with a temperature-regulating effect.

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] Example 1

[0019] Combination Figure 1 This embodiment will be described in detail below. The present invention relates to a temperature-regulating wool blended yarn, comprising a core yarn 1, a temperature-regulating fiber covering layer 2 covering the outside of the core yarn 1, and a wrapping filament layer 3 wrapping the outside of the temperature-regulating fiber covering layer 2; the core yarn 1 is a blended wool wool coarse-spun yarn; the temperature-regulating fiber covering layer 2 is microcapsule phase change viscose fiber; the wrapping filament layer 3 comprises lyocell filaments 31. The blended wool wool coarse-spun yarn is a blended cotton wool coarse-spun yarn. The yarn of the coarse-spun yarn is relatively fluffy and has good warmth retention; its yarn count can be selected according to actual needs. Lyocell filaments have good luster and can improve the luster of the blended yarn.

[0020] According to the core-spun yarn production process, temperature-regulating fibers are wrapped around the outside of the core yarn 1 to form a temperature-regulating fiber layer 2. Phase change materials (PCMs) are a class of substances that absorb or release heat from the environment through their own reversible phase change within a certain temperature range.

[0021] Phase change material paraffin is selected as the core material, toluene-2,4-diisocyanate (TDI) and hexamethylenediamine are used as wall materials, and the hydrolysate of the synthetic copolymer styrene-maleic anhydride (SMH) is used as an emulsifier. In-situ polymerization technology is employed to encapsulate the phase change material within microcapsules, thus producing phase change microcapsules. High-quality cotton and wood pulp are selected as raw materials, and viscose fiber spinning is used. Through impregnation, pressing, aging, and xanthation, cellulose xanthate is obtained. Then, phase change temperature-regulating microcapsules are added, mixed, filtered, and matured to obtain a spinning adhesive with an effective content of 10% for the temperature-regulating microcapsules. This adhesive is sprayed into a coagulation bath at 48℃ to form the microcapsules. After stretching, refining, and drying, viscose-based microcapsule temperature-regulating fibers are obtained.

[0022] Example 2

[0023] Combination Figure 2 This embodiment will be described in detail below. The temperature-regulating wool blended yarn involved in this embodiment differs from that in Embodiment 1 in that: the wrapping layer 3 further includes mercerized wool worsted yarn 32, and the mercerized wool worsted yarn 32 is arranged in the opposite direction to the winding direction of the Lyocell filament 31.

[0024] Mercerized wool is a type of wool yarn produced through the mercerizing process in wool dyeing and finishing. This process involves chlorinating the wool and softening the proteins on its surface, resulting in a soft and lustrous yarn. Mercerized wool has an excellent hand feel and is more durable and gentler on the skin than traditional wool yarn.

[0025] Example 3

[0026] Combination Figure 3 This embodiment will be described in detail below. The temperature-regulating wool blended yarn involved in this embodiment differs from that in Embodiment 1 in that an antibacterial fiber covering layer 4 is provided between the core yarn 1 and the temperature-regulating fiber covering layer 2. The antibacterial fiber covering layer 4 uses silver-impregnated antibacterial cotton fiber.

[0027] Example 4

[0028] The temperature-regulating wool blended yarn involved in this embodiment differs from that in Embodiment 3 in that the antibacterial fiber coating layer 4 uses Tianlian fiber.

[0029] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
