Stitching-free heat-preserving clothes and production method thereof

Abstract

The invention provides a stitching-free heat-preserving clothes and a production method thereof. The production method comprises a thermal joint step and a clothes forming step, wherein the thermal joint step is carried out: a foam-typed first layer which is made of thermoplastic polyurethane raw material is joined with a film-shaped second layer which is made of the thermoplastic polyurethane raw material in a heating way so as to form a heat-preserving clothes material; and then the clothes forming step: the heat-preserving clothes material is made into a stitching-free heat-preserving clothes. The air chambers of the thermoplastic polyurethane foam are used for maintaining the heat of the body, so the heat of the body is prevented by the air chambers so as no to be easily scattered, thereby realizing the heat preservation; in addition, through the film which is made of the thermoplastic polyurethane raw material, and the film is delicate and thin, so the wind, snow and rainy water are difficult to pass through the film, thereby realizing the wind prevention and the water prevention.

Description

technical field [0001] The invention relates to a garment and a manufacturing method thereof, in particular to a threadless heat-retaining garment with a human body heat-retaining function and a manufacturing method thereof. Background technique [0002] Generally, there are patent cases related to warm clothing, such as Taiwan Announcement Nos. M251474, M272398, M280068, M293683, M302909, M338811 and other new patent cases. Their designs are all electric heating. Components, and through the power supply, to generate electric heat. [0003] refer to figure 1 , 2 , taking the Taiwan Announcement No. M302909 new patent case as an example, it utilizes long stainless steel metal fibers 11 and common fiber yarns 12 to weave each other, and then connects the power supply 13 to the two ends of the long stainless steel fiber 11, so that the clothes 1. Electricity generates heat to keep warm. [0004] However, the first thing to note is that such fiber woven clothing1 is usually ...

AI Technical Summary

Problems solved by technology

[0004] However, the first thing to note is that such fiber woven clothing1 is usually stitched together using tools such as needles and threads, such as figure 1 Most of the sutures 14 shown in the figure are between one piece of back covering 15 and two front coverings 16 of the clothing, but the strength of the suture 14 itself is not enough, and it is often easy to break or open due to external force. Therefore, outside air or rainwater will pour in from between the two pieces of clothing, affecting the warmth retention and moisture resistance of the clothing 1

[0005] In addition, once the electric energy is exhausted, the clothes 1 with this electric heating design can no longer continue to play the function of heating and keeping warm, especially in remote environments, such as high mountains and polar regions, where the electric energy cannot be easily replenished. necessarily limited

[0006] Furthermore, since the power supply 13 is installed in the clothing 1, it will obviously increase the overall weight, and the user will inevitably form a load on the user's body if he wears the clothing 1 for a long time, which will greatly affect the mobility.

[0007] In addition, the clothing 1 also lacks a windproof and waterproof design, so it cannot achieve a good blocking effect against wind, snow and rain in the external environment, and naturally the overall warmth retention effect will be greatly reduced
