Polyester is a widely used synthetic fabric. Because it is a plastic compound made of petroleum by-products, polyester melts and may melt when exposed to excess heat. This makes the production Woven fabrics such as felt. However, there are also woven and knitted polyester fabrics. Due to the different production methods, there are various textures and weights in this fabric family. Different sewing techniques. Before sewing with polyester fabric, wash with cold water and then dry in low to medium heat. This will eliminate any excess coating or pigment that may interfere with your project. The smallest size fresh needle made of polyester fiber is most effective. Worn- The outside Needles have gaps and bumps that embed small fibers in polyester fibers, resulting in tears and folds. Over- The size of the needle can cause an unattractive visible hole, weakening the seam. Knitting polyester fabric is particularly prone to this problem. Polyester Fiber matches your fabric on elasticity. If using a polyester thread on a sewing machine or curler, wind the wire shaft loosely and sew at a slow to moderate speed to prevent the line from feeding too fast. The intense friction caused by improper threading can cause the polyester line to stretch. When cooled, the stretched fibers shrink, leaving an irreversible seam bundle. Cut polyester using band-nap layout. Cut pattern pieces that maintain the same direction for each piece. The commercial pattern has an arrow in the direction that can be used to align the pattern. Making a picture sheet using a nap layout requires more fabric than not using Nap, so be sure to read the material quantity list carefully when purchasing fabric. Before cutting the pattern piece, the iron folds Flat lines with synthetic fabric iron set. If the crease cannot be removed, remove the affected part of the fabric. Cut satin polyester with sharp scissors. You may have to use the pattern weight when tracking the fabric. Stick your fabric to a few paper towels or white computer paper to create a stable non-slip backing. This backing prevents the fabric from sliding with its own, hand or sewing machine platform. Always finish the satin hem with narrow edges Fold or roll edges to prevent folding edges.
