Wearable bra for measuring thermal resistance of bra

Abstract

The invention discloses a wearable bra for measuring the thermal resistance of the bra, and the method comprises the following steps: wearing a wearable electric heating bra on a mannequin, then wearing a bra to be measured, and adjusting and setting the heated part of the wearable electric heating bra according to the style of a bra, so that the heat passing through the bra can be accurately measured, and a heat preservation index of the bra product is further calculated, such as a Crow value. The wearable bra for measuring the thermal resistance of the bra can be worn on a mannequin, then the bra to be tested is put on, and the thermal insulation performance is tested, so that the wearable electric heating bra is closer to the wearing state of a product than fabric testing, and the thermal insulation performance of the bra can be measured by utilizing the wearable electric heating bra, measuring the heat conduction quantity passing through the bra cups and calculating the thermal resistance. The test result is closer to the heat insulation state when a human body wears the bra, the data is more accurate, so that the seasonal environment suitable for the bra is determined, and the wearable electric heating bra is lighter and more convenient to move than a body warming dummy.

Description

technical field [0001] The invention relates to the field of bras, in particular to a wearable bra used for measuring the thermal resistance of the bra. Background technique [0002] At present, thermal dummies are usually used to measure the thermal insulation of clothing. But the thermal manikin is very heavy and inconvenient to move. [0003] Theoretical research and model making of thermal dummies in my country started relatively late, and my country began to pay attention to the development of thermal dummies only in the 1970s. The Military Equipment Research Institute of the General Logistics Department was the first batch of units that researched thermal dummies at that time. . In the 1970s, the Military Equipment Research Institute of the General Logistics Department successfully developed a constant temperature manikin, and in the 1980s, a variable temperature mannequin was developed, which was widely used in the development of various special clothing; since the 1...

AI Technical Summary

Problems solved by technology

[0005] Because bra products are usually composed of multiple layers and materials, and cannot be accurately characterized by the performance of fabrics

[0006] Bra products have different types of cups, such as: full cup, 1 / 2 cup, 3 / 4 cup, 5 / 8 cup, etc. The current thermal manikin cannot accurately measure the heat passing through various cups

Although there are thermal manikin products that can be used to measure women's clothing through a removable breast covering, they only simulate the female body shape and can't measure the heat passing through the bra more accurately.
