[0002] With the improvement of people's living standards and the change of aesthetic concepts, suits, as a choice of clothing for formal occasions, have gradually changed from a single business function to a diversified function. Especially in cold weather, people need suits to be formal and have good warmth retention. However, traditional suits often fail to take both into account.

[0003] CN116587683A discloses a heat storage and heat preservation fabric, which is a double-layer composite structure, the inner layer is a skin-friendly layer, and the outer layer is a blend of hollow polyester fiber and heating fiber in a mass ratio of 2-3:3; the heating fiber is evenly dispersed with far-infrared ceramic powder, which has the function of absorbing light and generating heat, and the heat preservation effect of the hollow polyester fiber makes the fabric have heat storage and heat preservation functions. However, the ceramic fiber powder dispersed in the outer layer of the fabric is easy to fall off, resulting in unstable heat preservation performance.

[0004] CN107245886A discloses a high-efficiency heat storage graphene down filling material, which is made by mixing graphene fibers and down in a certain ratio; stirring them by a mixer, combing them by a combing machine, shaping them by a Duoduo down shaping machine, and finally packing them by a packaging machine, which effectively improves the thermal insulation performance of the filling material. However, due to the large volume of down filling, it is easy to expand, which affects the appearance of suits.

[0005] As an important high-performance fiber material, far-infrared ceramic fiber has the characteristics of high temperature resistance, corrosion resistance, and excellent mechanical properties. In particular, its thermal stability far exceeds that of high-performance polymer fibers, and its thermal insulation and oxygen aging performance are even better. It has become an important raw material for industrial textiles. However, it is often added in the form of powder, which results in low adhesion and easy to fall off after washing. At present, how to use far-infrared ceramic fibers for thermal insulation suits, improve their adhesion, and enhance the thermal insulation effect has become a technical problem that needs to be solved. Summary of the invention

[0027] Beneficial effects:

[0028] The invention discloses a suit with a detachable ceramic fiber thermal lining, wherein the outer fabric has good thermal insulation performance, the thermal insulation layer is light and flexible, and can be used for thermal insulation and heat storage, the inner fabric has good flexibility and skin-friendly performance, and the comfort level is improved, and the thermal insulation filling material is light and warm, and has good cold resistance, and meets the business performance requirements of suits that can still be worn in cold weather.

[0029] The fabric layer of the suit is made of wool fiber and polyester fiber blended fabric, which not only maintains the stiffness of the suit, but also has certain warmth retention and breathability. The suit of the present invention has a detachable lining design, which is convenient for users to replace according to different scenes and climates, improves the practicality and flexibility of the suit, and the suit is more in line with the aesthetic needs of modern people while maintaining the formality of traditional suits.

[0030] The thermal insulation filler used in the present invention adopts T cotton fiber and polyurethane fiber as fillers, and adds silica aerogel. Due to the unique nanoporous structure of silica aerogel, the modified far-infrared ceramics are chemically combined with the silica surface groups, thereby increasing the dispersibility of the modified far-infrared ceramics in the sol, increasing the adhesion, and increasing the stability of the system. Nanographene has thermal insulation performance and can be adsorbed on the surface of polyurethane fibers to increase mechanical properties and thermal insulation and heat storage functions for the system, achieving the effects of being light, thin, soft, storing heat, and insulating and keeping warm, improving the thermal insulation performance of the suit, and achieving the effect of being beautiful to wear.

[0031] The inner fabric of the lining used in the present invention is a composite blend of chitosan fiber and silk fiber with good moisture absorption and antibacterial properties to increase skin-friendly comfort. It is combined with volcanic rock fiber to convert moisture into thermal energy, which is rapidly heated in the filler through the thermal conductivity of graphene. At the same time, the outer fabric of the lining is a low thermal conductivity material, which can lock in heat in cold weather and play a role in heat preservation.

[0032] In the inner lining and outer fabric used in the present invention, the aluminum silicate blended yarn is immersed in a heat preservation and heat storage functional liquid. While formaldehyde and resorcinol are cross-linked, formaldehyde is also cross-linked with the aluminum silicate blended yarn. The adhesive formed by the cross-linking of formaldehyde and resorcinol is grafted onto the aluminum silicate blended yarn. While the adhesive is coating the aluminum silicate blended yarn, the adhesive can be firmly fixed on the aluminum silicate blended yarn through chemical cross-linking, thereby effectively preventing the dispersion of fibers in the yarn, improving the strength of the yarn, increasing the mechanical strength of the fabric, and reducing the pore size of the fabric, thereby achieving the effects of windproof, heat preservation and cold protection.
