Technical Field

The invention relates to the field of bra production research and development testing devices, in particular to a bra heat preservation tester.

Background

At present, more than 100 experimental body-warming dummy are made in the research of the body-warming dummy at home and abroad. The development process of the warm-body dummy mainly goes through three stages. The first stage is the concept of clo, namely the thermal resistance of the clothing, proposed by the American scholars Gagge and research teams thereof in 1941, and the American military need climate research institute developed the first generation of warm-body dummies, which are single-stage warm-body dummies, and are used for testing the thermal resistance of the static clothing. Early thermal manikins generally served the military and only later gradually expanded to other areas, but currently thermal manikins remain important tools for testing military requirements. The second section is a sectional type warming dummy which is born in the 60 th of the 20 th century, and compared with a single-section warming dummy, the sectional type warming dummy has the advantages that each section can be independently controlled and independently heated, some simple postures of a human body are simulated, the temperature state of the body surface of the human body is more truly simulated, and the static and dynamic thermal resistance of clothes can be measured. The third generation of warm-body dummies was a sweating warm-body dummies, made in the 70 s of the 20 th century by Goldman in combination with professor mechells, etc. Compared with the first two generations of body warming dummy, the third generation of body warming dummy can simulate the temperature of the human epidermis more truly, and the measurement of the thermal resistance of the clothes is more accurate.

Theoretical research and model making of warm-body dummies in China began late, and since the 70 s of the 20 th century, China began to attach importance to the development of warm-body dummies, and the general logistics military equipment research institute was the earliest unit for researching warm-body dummies at that time. In the 70 s of the 20 th century, the institute of military equipment in the general service part successfully developed a constant-temperature body-warming dummy, and in the 80 s developed a variable-temperature body-warming dummy, which was widely applied to the development of various special clothes; the sweating thermal manikin began to be studied in the 90 s and a sweating thermal manikin test system was successfully developed in 2000. The first global warming dummy 'Walter' made of special fabrics was invented by the fourth professor of Van jin Tu of the university of hong Kong Finishen in 2002, and is used for measuring the thermal resistance of clothes.

The heat insulating performance of the existing warm body dummy measurement clothes cannot accurately represent the heat insulating performance of the female bra. Although the thermal insulation performance of the garment can be measured by the thermal manikin, the thermal insulation performance of the local garment corresponding to each zone can be measured and calculated due to the fact that the thermal manikin is heated in a zone mode, but most of measurement objects of the thermal manikin are conventional garments with large coverage areas for human bodies, and for special garments only covering the local human bodies, the measurement objects are as follows: the measurement result of the bra is different from the actual wearing feeling. After a human body wears the bra, the bra only has a remarkable influence on the heat dissipation capacity of a small area covered by the bra but not on the whole body, and the traditional method for solving the heat retaining property of the clothes is to calculate the area weighting of the thermal resistance of each area of the human body, so that the method is significant for conventional clothes with large human covering materials, but is not suitable for bra products. For example: if a full cup brassiere has a thermal resistance of 1 clo of cup material, if the thermal resistance of the brassiere is calculated in an area-weighted manner, assuming that the brassiere coverage area occupies 3.2% of the human body surface area, the thermal resistance of the brassiere is 0.032 clo, and when the thermal resistance of the cup material is 2.2 clo, the thermal resistance of the brassiere is 0.0704 clo. If the thermal resistance of the two shirts or pants is 0.032 and 0.0704, respectively, and the difference between the two is 0.0384, the wearer cannot feel the wearer at all because the thermal resistance of the boundary layer air between the body and the garment surface can be as high as about 0.8. The heat sensation at the chest of the wearer of these two brassieres is very different. Therefore, the heat insulation performance of the bra cannot be reasonably represented by calculating the thermal resistance of the clothes by using the traditional human body whole body area weighting mode. Solving for the heat dissipation through only the bra coverage area is important to evaluate the heat and moisture comfort performance of the bra product.

Because brassiere products are also typically constructed from multiple layers, multiple materials, and cannot be accurately characterized by the properties of the fabric.

Brassiere-like products have different types of cups, such as: full cup, 1/2 cup, 3/4 cup, 5/8 cup, etc., the current body warming dummy cannot accurately measure the heat passing through various cups. While the thermal manikin product may be used to measure feminine garments through a removable breast cover, it merely simulates the body shape of a woman, and its heating zones are not adjustable to the type of brassiere cup, and likewise do not measure the amount of heat passing through the brassiere relatively accurately. The invention is provided aiming at the defects of the measuring equipment and is specially used for heat preservation performance testing equipment of bra products.
