Most micro-fibers are made from polyester although some are made from nylon and rayon and most recently, acrylic. Micro-fibers may be blended with other fibers including cotton, linen, wool, rayon or Lycra spandex. Micro-fibers increase the washability and easy care of the other fibers in fabrics. Polyester micro-fibers will be used in blends because some clothing companies have found that the pure micro-fiber fabrics pucker when sewn. Micro-fiber fabrics are very versatile and come in various weaves and weights. They can be sanded or sueded giving a super-soft, buttery texture on the fabric surface. For more information see micro fibers.
Micro-fibers can be machine washed and dried (see laundry tips or fabric care). They are strong and lightweight, yet porous and more breathable than conventional polyester.
Design features such as shirt sleeves, kimono, raglan, dolman, cap sleeves and extended shoulders are desirable. These are easier to sew than traditional set-in sleeves since micro-fibers are a little more difficult to ease.
Particularly attractive are such details as gathers, soft pleats, cowl necklines, topstitching and edge stitching.
Be sure to test both fusible and sew-in interfacings. Select the type that gives the right support and control for your fabric. If using a fusible interfacing, fuse to the facing and undercollar.
Preshrink fusible interfacing by placing it in hot water for 10 minutes. Squeeze out water and roll in a towel to remove excess moisture. Hang on a towel rod to air dry.
Pins: Use fine, high quality pins. Pin in the seam allowance as holes will remain in the fabric. Place pins parallel to the grain line. Some holes can be hidden by using your thumbnail to scrape across fabric holes.
Needles: Select very fine sewing machine needles; size 60-70 (European) or 8-10 (American).
Sharp shears or a rotary cutter and mat will allow for smoother cut edges.
Set the stitch length on the sewing machine at 10-12 stitches per inch or 2 to 2.5 mm.
Select zippers with a nylon coil.
Pleats may be set by brushing with 50/50 solution of white vinegar and water. Always test first on a fabric scrap for color fastness.
Finish seams with pinking, edge stitching, welt stitching or use a serger.
Buttons and buttonholes, buttons and loops, and zippers are suitable closures.
Treat hems by fusing or machine topstitching. Select a fusible web that is soft and lightweight. A narrow, machine-rolled hem may not hang as softly at the edge. Blindstitched hems by hand or machine are difficult to make invisible on the right side.
