The Effect of Differences of Weft Yarn Type and Fabric Structure on The Physical and Mechanical Properties of Children and New Born Clothes

This research aims to enhance the physical and mechanical properties of children and new born clothes , by identifying the best fabric structures with the best type of  weft yarns, which can be used for underwear and outerwear of children and new born clothing , that realize comfort properties , by producing 100% cotton fabrics with three simple fabric structures (plain 1/1, twill 2/2 and satin 4) and three types of weft yarns (single, twined and flat)  . This research follows the analytical experimental approach to achieve the hypotheses and objectives of research.
The results showed that:
1) The best sample is the 100% cotton fabric, which is satin 4 with flat weft yarn type  with a quality factor 90.61%
2) The lowest sample is the 100% cotton fabric, which is plain 1/1 with single weft yarn type , with a quality factor 84.82%
3)The best fabric that can be used as underwear for new born children is the 100% cotton fabric , which is satin 4 with flat weft yarn type, which realizes the best wearing properties like (highest white - higher air permeability - less absorption time - less roughness)
4) The best fabric that can be used as outerwear for new born children is the 100% cotton fabrics , plain 1/1 structure with a twined weft yarn type, which realizes the best wearing properties like (highest tensile strength and highest elongation).
5) Regarding the wrinkle resistance property, the best fabric was satin 4 with a twined weft yarn type. In terms of weight per square meter, the best fabric was twill 2/2 structure with single weft yarn type.
After that, the research has introduced some advises and suggestions :
1 –Make more attention to children's clothing , especially in the time of newborns as a try to enhance the physical and mechanical properties through the stages of spinning and weaving to achieve the required comfort properties for this stage.
2 – Encouraging of companies and garment factories to make more attention for general research, especially children and new born clothes , as a try to link the results of scientific research with civil society and to be applicable.
