preparation example Construction

[0033] Correspondingly, the present invention provides a method for preparing a sheath-core fiber with luminous far-infrared function, including the following steps:

[0034] Provide luminous masterbatch containing rare earth luminous materials and far-infrared masterbatch containing far-infrared ceramic materials respectively;

[0035] Melt spinning the luminous masterbatch and far-infrared masterbatch to obtain a core-sheath fiber with luminous far-infrared function. The skin layer of the core-sheath fiber is a polymer layer containing rare earth luminous materials, and the core layer is Polymer layer containing far-infrared ceramic material.

[0036] The preparation method provided by the present invention uses textile polymer raw materials as substrates to prepare functional fibers with luminous and far-infrared functions, namely luminous far-infrared functional fibers, which can improve the safety and warmth of the wearer and is suitable for outdoor activities at night Wear and...

Abstract

The invention provides a sheath core fiber with a night light far infrared function and a preparation method thereof. The sheath core fiber is a complex fiber comprising a sheath layer and a core layer, wherein the sheath layer is a polymer layer containing a rare earth noctilucent material; the core layer is a polymer layer containing a far infrared ceramic material. The invention provides the fiber, which is the sheath core complex fiber comprising the sheath layer and the core layer, the polymer layer containing the rare earth noctilucent material is adopted as the sheath layer, and the polymer layer containing the far infrared ceramic material is adopted as the core layer. The sheath core fiber provided by the invention is the multifunctional complex fiber, which can be luminous continuously at night, has a far infrared warmth retention function, and is durable and stable in functionality, high in washability, wide-range in application, and beneficial to being applied.

Description

Technical field [0001] The invention relates to the technical field of functional textiles, in particular to a sheath-core fiber with luminous far-infrared function and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, functional textiles have become a hot spot for industry research and development, and some functional textile products such as moisture wicking, night light, far-infrared warmth, and UV resistance have also appeared on the market. At present, the production of functional textiles mainly includes two methods of adding functional auxiliaries before spinning to make functional fibers and then weaving them into fabrics; or ordinary fibers woven into fabrics and then finishing them with functional auxiliaries. The product obtained from the former has a long-lasting effect and good washing resistance, but the treatment process is relatively complicated; the latter has a simple treatment process, but there are m...
