绗缝：是用长针缝制有夹层的纺织物，使里面的棉絮固定。
Quilting: a long needle is used to sew a fabric with interlayer to fix the cotton inside.
绗缝制品通常由面料、填充料、底料三层物料组成，填充料形状也是各异，有絮片有散纤，被胎在使用过程中，经长期使用翻动蹂躏摩擦，容易产生形状不固定，流动缩团，厚度不匀等情况。
Quilting products are usually composed of three layers of materials: fabric, filling material and bottom material. The shapes of filling materials are also different. There are flocs and loose fibers. In the process of using quilting products, after long-term use, they are easily damaged by overturning and friction, resulting in unstable shape, flow and shrinkage, uneven thickness, etc.
为了使被褥外层面料和填充内芯之间贴紧固定，使填充物薄厚均匀，用缝纫线的线迹在三层物料上组合成无规则排列的，独立式的或者是有规则重复的各种图形轨迹，牢固地缝住三层物料。这些缝纫线图形轨迹既可以防止填充料(如喷胶棉、蚕丝，羽绒等)的移动，还能增强缝制品的立体感，使其同时具有较好的装饰功能。这道增加美感与实用性的工序，就叫绗缝工艺。
In order to make the outer fabric of the quilt and the inner core of the filling close and fix, and make the filling thin and even, the stitches of the sewing thread are combined on the three-layer materials to form a variety of graphic tracks, which are arranged irregularly, independent or repeated regularly, to sew the three-layer materials firmly. These sewing thread pattern tracks can not only prevent the movement of filling materials (e.g. cotton spray, silk, down, etc.), but also enhance the three-dimensional sense of sewing products, so that they have better decorative functions at the same time. This process of increasing aesthetic feeling and practicability is called quilting process.
