A woman’s mannequin for testing rain protection clothing

Editorial

A new technical anthropometric dummy (with real anatomies) in women's configuration has recently been purchased by Centrocot's Comfort laboratory, with the aim of adapting to and better investigating the specific peculiarities of women's clothing.

The mannequin has articulated elbows and shoulders to facilitate the stages of dressing, also you can remove completely, through a magnetic device, both the arms and the part of the leg below the knee and everything is made of water resistant materials.

The mannequin is 171 cm tall and corresponds approximately to a size 38 (bust: 86 cm; waist 63: cm; hips: 92 cm).

The purpose is to facilitate the design and development of an entire field of clothing, but also its accessories and critical details (e.g. zippers, velcro, seams and inserts) specifically for women’s clothing.

The context of its use is the Test Standard UNI EN 14360 – “Impact with high energy droplets” – whose purpose is to determine the resistance of clothing (jackets, pants, suits but also any single part) to artificial rain and with respect to an exposure for a specific period of time.

The dummy is prepared with a set of undergarments made of a special absorbent fabric and then dressed in the clothing to be tested. The standard dwell time in the rain is one hour (but it is possible up to 8 hours and more) and the amount of water is 450 liters/hour.

Then it is possible to evaluate the wet areas found on the undergarments as well as measure their weight to determine both the amount of water retained by the tested garment and the amount of water that penetrated inside.

The amount of water for this rain tower test is quite high (only in tropical regions, in fact, the rainfall values can be greater than 600 liters/m²/hour), for this reason it is not enough that a garment is made of excellent “waterproof” material but good design practices are required and above all seams are applied and protected in a workmanlike manner to ensure that the dummy remains dry after an hour (or more) of downpour. The advantage of such high intensity rain is that leaks occur more quickly and therefore the duration of the test can be shortened (i.e., prolonged exposure situations that actually occur can be simulated).

The structure of Centrocot’s Rain Tower has recently been implemented by introducing the possibility of performing the test using sprays that produce a flow of water of about 600 l/hour. In fact, 4 pairs of nozzles were installed on the sides of the dummy placed on two horizontal planes, the first at knee height (to have coverage from the feet to the waist of the dummy) and the second at chest height (to have coverage from the waist to the head). The total flow of water that, in this configuration, invests the clothing is intended to simulate particularly severe and extreme environmental conditions.

The woman’s version of the mannequin will now join the mannequin already supplied and with which the laboratory has so far carried out tests in compliance with regulatory requirements as well as various research, development and innovation activities with major companies in the textile-clothing-fashion sector and research institutes.
