Study on the Sewability of Special Fabrics
Jee Hye Chang
This study was carried out on the Sewbility of Urethane Foam usually used as coldproof lining. The Sewability was estimated with the Puckering Grade and Seam Efficiency according to the thicknes of urethane foam, fineness and material of sewing thread, and the sort of covering fabric. The result shows the following ; 1. The thick foam proportinally shows the low Puckering Grade. 2. Effect on the sewability is small in fineness of sewing thread but large in material. Especially silk thread shows the greatest sewability in foam sewing. When the material of covering fabric is same as that of sewing thread (for example ; p/c fabric and p/c thread) the sewability is excellent in special. 3. Taffeta in covering foam is not suitable to foam sewing, satin and twill show superior sewability without reagrd to the thickness of foam. 4. In case of sewing foam covered with tricot, optimum thickness of foam and fineness of sewing thread through pretest must determine. 5. The thicker foam is the better seam efficiency tends, and Seam Efficiency largely effects to the strength of the sewing thread itself. 6. The seam Efficiency can heighten with the strength of sewing thread in proportion to that of covering fabric.
