Background

Today, people around the world advocate and promote their national culture and tradition, traditional apparel represents a national image and culture. The so-called "clothes eating and housing", and "dress" is the first place ranked in the folk custom of life, and the importance of dress can be seen. The Chinese jacket and the sea cheongsam are merged into a Chinese clothing making technology project, a third batch of national non-ancient famous records is selected in 2011, and the protection and development of the traditional clothing of the non-ancient type are more widely regarded. Traditional things are not dead, static antiques, but rather a living, legacy ethnic resource. Because the protection is 'live', the traditional culture protection at present cannot be carried out only from the protection idea, but is protected and inherited by activating the protection idea. The modern value is embodied by leading the traditional beauty to have the modern chamber tone while insisting on the national context.

With the development of intelligent apparel, intelligent textiles, and TUIs, information display devices are changing from rigid and planar objects (such as CRTs or liquid crystal displays) to flexible and tangible displays (such as EL flexible displays) to fabric-based displays. Fabric-based displays can sense and react to external conditions while also preserving the style and technical characteristics of textile materials, textiles, are more natural than rigid, flexible displays, blend in with apparel, and users are aware of its presence only when it is conveying the necessary information.

Disclosure of Invention

Detailed Description

The technical scheme of the invention is further explained by combining the drawings and the embodiment.

Most of the traditional Chinese cheongsam is made of silk fabric, and in order not to damage the fine, light and glossy texture of silk, the fabric is not modified in the embodiment, and a conductive wire is not woven into the fabric. In the design of the heating mechanism, the invention adopts a sandwich structure, namely, the uppermost layer is an expression layer, the middle layer is a heating layer, and the lowermost layer is a heat insulation layer.

As described in detail below.

(1) Presentation layer and tinting

The reversible thermochromic material is the basis of temperature-sensitive fabric color change and is applied to fabric color change design. The thermochromic material (existing material, not the innovation of the invention) has different activation temperatures and color settings in two states, and the colors can not meet the requirements of actual color-changing patterns generally, especially in the design of color-changing patterns needing to be changed gradually, the materials can meet the requirements of thousands of colors, which is not practical and efficient, so that the limited thermochromic material can have more color expressions by designing and using methods. While thermochromic dyes have been available in a wide variety of color choices, ranging from colored to colorless, it is generally desirable that the pattern appear rather than disappear after being activated. And because the existing thermochromic dyes changing from 'colored' to 'colored' are not much in color and cannot meet the requirements of pattern design, the leuco dye-based color-changing dyes are used in the invention, and are mixed with common dyes to prepare the required color according to different mixing ratios. In the initial state, the color of the dye is mixed color, when the temperature is increased, the color-changing dye changes from colored to colorless, while the color of the common dye is remained, thereby realizing the change from colored to colored.

In the embodiment, in the aspect of the combination process, in order to keep the stroke of the traditional Chinese painting, the pattern is drawn on the cheongsam in a hand-drawing manner. In order to hide the pattern before discoloration as much as possible, the example selects silk fabric of dark gray at the time of making the cheongsam, and makes the color after blending as close as possible to the color of the cheongsam fabric at the time of subsequent blending of the discoloration dye with the general textile pigment. According to the design scheme of the dynamic color-changing pattern, the required colors are as follows: graying to white, graying to dark red, graying to light red, graying to dark green, graying to light green, greening to brown, greening to yellow, and the like. The leuco dye-based color-changing dye and the common dye are mixed according to a proportion to prepare the color-changing dye, if the green color is changed into the yellow color in the embodiment, the leuco dye-based color-changing dye and the yellow common dye are mixed according to a ratio of 1:1.2, and the specific proportion can be finely adjusted according to the color requirement. The color formulation for a leuco dye-based color change dye is thus given by:

before low-temperature color change, the color A is the color of the color-changing dye 1+ the color of the color-changing dye 2 +. cndot. + the color of the color-changing dye n + the color of the common dye;

after high temperature color change, the color B is the common dye color plus white;

wherein, the color addition effect of the color A before low-temperature color change follows the three-primary color blending formula, and a little white in the color B after high-temperature color change is the residual white of the leuco dye-based color change dye after color change at the temperature.

The lines and patterns on the traditional Chinese cheongsam usually have their own connotations and symbols, and most of the patterns like flowers, birds and beasts like peony, magnolia, plum blossom, peacock, phoenix and the like are favored. In this embodiment, magnolia with a smaller flower pattern is selected.

(2) Heating mechanism design and cheongsam dynamic pattern design

Considering the heating range and the heating effect, the magnolia flower with smaller flower shape is preferred in the embodiment, the dynamic change mode of the magnolia flower is designed according to the concept of four-season change, different parts are activated at different moments to depict the scenes that the flower branches sprout from new leaves, contain buds, flourish to the golden storm, and an expanse of white snow. The specific method comprises the following steps: electrically heating the conductive cloth of the flower bud and the green leaf part in the design pattern at a time t1 to discolor the flower bud and the green leaf part; at the time t2, conducting electricity to heat the conductive cloth of the flower part to enable the flower part to change color; further heating the conductive cloth of the green leaf part at a time t3 to turn the green leaf yellow; at time t4, the white snow portion is electrically heated to change its color.

The PCB control circuit is well integrated on the clothes to meet the requirement of intelligent clothes wearability, the independently developed circuit board is small and attractive in appearance, four sewing holes and eight PIN ports are reserved, the circuit wiring layout is neat and safe, positive and negative connecting wires are separated, and the problem of short circuit is avoided. While integrating the circuit layout into the cheongsam lining to hide the circuit.

(3) Heating layer

In the heating layer, a conductive cloth is used for heating, and a conductive sewing thread is used for connection. By way of example, and not limitation, the conductive Fabric used is an EeonTex High-Conductivity Heater Fabric-NW170-PI-20 having a resistance of 20 ohms/square. In order to provide a more uniform heating effect on the conductive cloth, the heating cloth is cut into pieces of about 30mmx40mm, and the pieces are connected by a resistor of about 15 to 25 ohms, and are spliced according to the size of the pattern. The voltage required for each piece of conductive cloth to heat up in 15 seconds is 8V to 12V, and the higher the voltage, the faster the heating speed. Considering that the total voltage cannot be too large, the embodiment connects a plurality of pieces of conductive cloth in parallel rather than in series. The quantity of the conductive cloth is inconsistent every season, the pattern activated in summer is the largest, the total number of the conductive cloth is the largest, the current is about 2.8A, and the conductive cloth is within the bearing range of the PCB. The electrically conductive sewing thread is used only as a connection and not for heating, so that the smaller its resistance is, the better. The example used a novel textile conductive thread made of very fine twisted copper-silver alloy wires and covered with an insulating coating. The conducting wire is thin and high in strength, can be sewn by using a sewing machine, and is convenient to arrange and run on the cheongsam.

Further innovation, because of the resistance difference between the conductive cloth and the conductive wire, the contact point is always heated first and the temperature is highest when heating. In order to obtain a uniform heating effect, the embodiment uses the copper tape to enlarge the contact area of the conductive sewing thread and the conductive cloth, and uses the good thermal conductivity of the copper tape to better transfer heat. The uneven heating resulting from the first heating of the contact points is not necessarily a challenge but may be an opportunity, which may be exploited to design the dynamic effects of the heating process. For example, the contact point may be placed at the root of the leaf, in order to start the gradual green-turning of the leaf from the root to the top. When the power is on, the root part is always heated first and turns green, and the control of the dynamic effect is realized.
