Description

Down jacket with back heat and humidity internal circulation system and manufacturing method thereof Technical Field The invention relates to the technical field of clothing design, in particular to a down jacket with a back heat-moisture internal circulation system and a manufacturing method thereof. Background In a low-temperature environment, the down jacket is used for fixing static air through a three-dimensional fluffy structure of down fibers to realize efficient warm keeping, and is widely used in scenes such as commuting and outdoor. However, the traditional design still needs to be optimized in terms of the scene suitability of the heat and humidity management, and especially the heat and humidity balance regulation and control of the back area does not form a full-scene solution. The back is the main heat and humidity generating area of human body, and can generate metabolism heat and sweat steam during the activity. The traditional down jackets are used for guaranteeing warmth retention, and high-surface-density dense fabrics and uniform dense filling are adopted, so that although heat loss is reduced, the internal and external air exchange rate of the clothing is low, sweat steam is difficult to discharge, and a local high-humidity environment is formed. The environment can reduce the fluffiness of the down feather and attenuate the warmth retention property, and also break the balance of skin microenvironment, cause discomfort and risk of catching a cold, and the problem is more prominent when the indoor and outdoor temperature difference is large. In the prior art, the fabric modification scheme improves ventilation, reduces windproof warmth retention, the filling structure is optimized to sacrifice back warmth retention, the moisture absorption material cannot be quickly dehumidified and influences portability, and the warmth retention and moisture removal requirements are not balanced. In order to meet the core requirements of consumers on 'strong heat preservation', the mainstream down jacket products in the current market generally adopt the design thought of 'high sealing and high filling', namely, the outer layer is made of high-surface-density dense fabric, and the inner part is made of down filling modes with uniform and dense whole clothes. The product can effectively separate heat loss in low-temperature static scenes (such as indoor sedentary and outdoor short-time stay in winter), but the heat and humidity problem of the back area is remarkable in dynamic scenes (such as daily commute walking and outdoor mild exercise), on one hand, sweat steam generated by human back metabolism cannot be discharged through a high-sealing fabric and a dense filling structure, a continuous high-humidity environment is formed between the inner layer of the garment and the skin, so that a wearer has obvious sticky feeling, when the indoor and outdoor temperature difference is more than or equal to 15 ℃ (such as from-5 ℃ outdoor entering into a 20 ℃ room), the high-humidity environment can accelerate skin temperature fluctuation, the risk of catching a cold is increased, on the other hand, moisture accumulated for a long time can be attached to the surface of down fibers, the fluffy structure of the down fiber is damaged, namely the common white duck fluff in market products is 500-600 FP%, the fluffy degree after the fluffy degree is reduced to below 400 FP, the static air retention amount is reduced by more than 30%, the general problem of obviously reducing the effect after the wearing for 1-2 hours is directly caused. The electric heating down jackets have the problems of local overheating and uneven warmth retention, and rely on external power supply, so that the electric heating down jackets are low in comfort level and inconvenient to wear for a long time or perform outdoor activities. Disclosure of Invention The invention aims to overcome the defects in the prior art, and provides a down jacket with a back heat and humidity internal circulation system and a manufacturing method thereof. In order to solve the technical problems, the invention adopts the following technical scheme: In a first aspect, the invention provides a thermal-wet internal circulation system of the back of a down jacket, which comprises a moisture absorption layer, a heat-preserving breathable layer and a heat storage layer; the moisture absorption layer comprises a moisture absorption structure area and a ventilation hole area; The heat-insulating ventilation layer comprises ventilation layer cloth, a plurality of heat-insulating units and a plurality of groups of control units, wherein the heat-insulating units are soft cylindrical channel structures filled with heat-insulating materials, and the heat-insulating units are vertically arranged on the ventilation layer cloth; the heat storage layer comprises heat storage lining cloth and three-proofing fabric.
