UNDERWEAR

By Jane Kallesøe & Helle Knudsen

Being a woman you can get different types of underwear with different kind of characteristics that can be based on the comfort, the look etc.

We have choosen to focus on the finer underwear instead of for example simple cotton underwear, as finer underwear have other characteristics.

In this case the focus is on satin underwear that look wise give a more luxurious and expensive look.

An example of what type of underwear the chosen fabric can be used for. 

THE CONSTRUCTION

The material used for the underwear is made of 100% polyester, and has been dyed in a marine blue color.

The fabric is constructed with a 1/1 plain weave, and have a square meter weight at 102,6 g/m².

The tear proposition of the fabric is;

Warp: 20,44N

Weft: 18,80N

Normally underwear is produce as a knitted material, which makes the fabric stretchy. Because this fabric is woven, it isn't stretchy and that can give some other challenges when constructing the underwear. But satin is still one of the well-known fabric for underwear. 

THE WASHING TEST

Satin is one of the more delicate fabrics, and with this in mind we did the washing test at 40°C.

We decided to do 2 types of washing tests – 1 with peborat (an oxidative bleaching agent) and 1 without. We did the 2 types of washing test, because we all know that we don’t all wash our clothes the same, while some might be aware of what products they use, some just buy the cheapest on the market.

The differences in the result made us question; “Do we prefer to wash our clothing with or without this type of bleaching?”

Given the test result, we will prefer to wash our clothes with peborat, because of the transfer of the dyed isn’t as big as without. For example if focusing on a dark and white striped blouse, shirt etc., you don’t want the dark color to transfer to the white areas.
