Abstract
Description
Technical Field
[0001] This utility model relates to the field of fabric technology, and in particular to a denim patchwork jacquard fabric. Background Technology
[0002] Existing denim patchwork fabrics (such as) Figure 1 The preparation of the denim patchwork fabric (as shown) involves multiple steps, including material selection, cutting, piecing, and post-processing. First, a suitable denim fabric is selected as the base material. Then, denim pieces of different shapes and sizes are cut according to design requirements, ensuring neat edges to avoid frayed edges. Next, the cut denim pieces are pieced together according to the design pattern, using a sewing machine or by hand to ensure a secure piecing and prevent unraveling or pilling. After piecing, the fabric is washed and ironed to remove excess glue and impurities, making the fabric smoother. If necessary, a shaping treatment can be applied to maintain the durability of the piecing effect. The denim patchwork fabric prepared in this way is a complex and intricate process, involving multiple processes and requiring significant manpower and resources. Furthermore, the denim fabric requires substantial water resources for washing to remove sizing and excess dye, or to simulate natural wear to enhance its fashion appeal and added value.
