CHILDREN CLOTHES

By Jane Kallesøe & Helle Knudsen


When it comes to children wear there are some very important rules that need to be met. It is important to be aware of cords and other small parts, as children can choke, if they swallow small parts, or if the cord or drawstrings in caps get stuck in the equipment at the playground – swings or slides.
Older children can get long belts, drawstrings or loose hanging cords tangled in bicycle wheels etc.


 6 recommendations on drawstrings in children’s clothes.
1. Clothes for children up to 7 years (height 134cm) must not have cords or drawstrings in the hood or neck area.

2. Clothes for children between 7 years and 14 years shouldn’t have cords in the hood or neck area longer than 75mm or cords with free hanging ends. Cords in the head- and neck area shouldn’t be elastic – except shoulder straps and neck straps (“halter neck”).

3. Clothing for children shouldn’t have cords or strings with free hanging ends that is longer than 140 mm in chest- and waist area.

4. Neck straps (“halter neck”) in children’s clothes shall not have free hanging ends in the hood and neck area.

5. Children’s clothing with belts or cords, which are intended to be tied at the front, must not have loose ends that are longer than 360mm, measured when they aren’t bound and from the point at which they are to be bonded.

6. Other cords or drawstrings in children’s clothes shouldn’t hang down below the sleeve or hem of the garment. Drawstrings, functional cords and decorative cords at the lower edge of the pants must be completely on the inside of the pants.




Our chosen fabric for children wear


THE CONSTRUCTION
We have chosen this fabric for our children wear project, which can be used for t-shirts, pants & body stock.
The material of the fabric is 98% cotton and 2% elasthane % and its square meter weight is 219,2 g/m2.

The fabric is constructed as a single jersey that is produced with a circular knitted machine (see picture below), and has been printed with a direct print.


Single jersey consists of plain meshes on one side (right side of the product), and purl stitches on the other side (wrong side).
When the product is finish being knitted at the circular knitted machine, it will come out as a tube and the width of the fabric can vary from a few millimeters to 500 cm.
The chosen fabric has been cut in the side, and then added to the roll.



PROS & CONS

Cotton
Pros
Cons
·      High wear resistance
·      Good resistance to light
·      High strength when wet
·      Good absorbency
·      Washable at high temperature
·      Easy to color and postproces-sing
·      Poor insulation properties
·      Tendency to curl
·      Not elastic
·      Shrinks (in raw mode)
·      Takes long time to dry


Elasthane

Pros
Cons
·      High elasticity
·      Washable in high temp.
·      Can be produced in fine fibers
·      Strong in wet and dry condition
·      Dry fast

·      Poor insolation properties
·      Don’t tolerate chlorine bleaching
·      Almost doesn’t curl




TESTING

Washing
We did the washing test at 40°C for 45 min (DS/EN ISO 105-C06-2010, test no. C1M), in order to test the material for color staining and shrinkage.

The result of the washing test showed;
·      No shrinking
·      No staining to the fiber pad

Burst strength
We wanted to find out how big a force that is needed for the fabric to burst.
3 test were carried out, and the average of these gave us the final result – 236,1 kPa. In average it took 27,3 sec.

Peeling
The big difference in this test was the color fastness.
As seen on the below picture the color has faded after 18.000 turns in the peeling machine/box.
Also peeling has occurred and we have estimated this to be 3-4 on the scale.
