Key points in the design and production of polyester-cotton burnt-out fabrics Composite fabric information

1. Specifications of polyester fiber (filament) The linear density of polyester core yarn directly affects the style of burnout products. If the polyester yarn is too thin, the burnt parts will be thin and soft, but if it is too thick, the members will lack lightness. Therefore, the linear density of polyester core yarn should be selected according to the use and style of the fabric. For burnout fabrics used for decoration, the burnout area is larger, and taking into account the drape of the fabric, polyester yarn with a larger sample number, such as 7.6tex (68 denier), can be selected. For burnout fabrics used for summer clothing, the burnout area is small, and considering the concave and convex effect of the fabric, polyester yarn with a smaller special number, such as 5tex (45 denier), is selected. 2. Blending ratio The blending ratio not only has a great influence on the hygroscopicity and washability of the fabric, but also has a great relationship with the burnout effect and the quality of the finished product.
