Abstract:

Objective In order for fabrics to automatically adjust the moisture loss according to the change of human body humidity, the microstructure of pine cone leaves, which open and close following humidity change, was studied and simulated. Polyurethane coating was used on polyester-ammonia knitted fabric to form the active layer and the driven layer with big difference in moisture absorption and elongation, so that the pine cone-like functional fabric responding to moisture was developed. Its pine cone-like leaves can automatically open and close according to the change of the wearer's body humidity, and the humidity can be quickly adjusted to improve the comfort of the wearer.

Method According to the response mechanism of pine-ball-like fabric to humidity, a self-made testing device for fabric moisture conductivity was designed, including water vapor generation, fabric moisture exchange and moisture conductivity detection. The relationship between the leaf aspect ratio (the ratio of longitudinal dimension to transverse dimension of leaf opening), leaf direction (the angle between leaf opening direction and cloth warp direction of driven layer), coating attach rate (the ratio of coating weight to cloth weight of driven layer) and moisture conductivity of leaf opening time, opening angle, opening speed and effective opening rate of pine-like fabric was studied.

Results It was found that as the leaf aspect ratio decreased (Fig.7-9), the opening time of the leaves gradually increased, and other moisture conductivity indicators of the leaves, namely, full opening angle, opening speed and effective opening rate, increased at first and then decreased. The change of leaf aspect ratio had the greatest influence on the effective opening rate of pine cone-like leaves, fluctuating in the range of 73%-92%. When the leaf aspect ratio was 65%, all the properties were the best. With the increase of the blade direction (Fig.10-12), the moisture conductivity indicators of the pine-ball-like fabric, including opening time, opening angle, opening speed and effective opening rate, exhibited a sudden decrease. When the blade direction was 90° the pine-ball-like fabric had no obvious opening phenomenon when wet, and when the blade direction is 0° the pine-ball-like fabric was shown to achieve the best performance. With the increase of coating attach rate of pine-cone-like fabric (Fig.13-15), all properties were increased at first and then decreased except for the opening time of the leaves. The increase of coating amount had the greatest influence on the effective opening ratio of pine-cone-like fabric, which fluctuated in the range of 77%-93%. When the coating attach rate was 66.7%, the moisture conductivity of pine-cone-like fabric reached the best. When the aspect ratio of pine cone-like leaves was 65%, the direction of the leaves was the warp direction of the driven layer and the attach rate of the coating was 66.7%, the moisture conductivity of pine cone-like fabric was the best, with its opening time of 47s, opening angle of 85.59°, average opening speed of 1.82(°)/s and effective opening rate of 93%.

Conclusion According to the research on the factors affecting the moisture conductivity of pine-cone-like fabric, the change of pine-cone-like leaf direction has the greatest influence on the opening performance of the leaves. With the increase of the angle between the leaf direction and the warp direction of cloth, all the properties of pine-cone-like leaves drop rapidly until they close completely. The change of aspect ratio and coated attach rate of pine cone-like leaves had a great influence on the effective opening rate of leaves, followed by a certain influence on opening speed, but a little influence on opening time and opening angle.
