  • Publication number: 20080242177
    Abstract: A decorative fabric has at least one layer and forms two surfaces. The at least one layer is woven with at least two materials. The at least one layer is corroded by at least one chemical agent to make a smooth emboss pattern. The decorative fabric provides an aesthetic appearance and is soft and smooth.

  • Patent number: 7380420
    Abstract: A fabric with different thicknesses has an upper layer, a lower layer and at least one yarn layer made of firm yarn, connecting to and formed partially between the upper layer and the lower layer to from at least one thick section of the fabric. Multiple sections of the fabric without the at least one yarn layer are thin sections. Each of the at least one yarn layer is formed between two adjacent thin sections The fabric with different thicknesses is produced by a method comprising a mounting step, a forming step and a connecting step. The connecting step comprises connecting the upper layer partially to the lower layer by fibers to form the thin sections and connecting the upper layer to the lower layer by firm yarn to integrally form the at least one thick section to reduce the cost of the fabric.

  • Patent number: 7380421
    Abstract: A fabric has an upper layer and a lower layer. The lower layer connects partially to the upper layer to integrally form multiple connecting segments formed on the upper layer and the lower layer. The at least one channel is formed on the upper layer and the lower layer and is formed respectively between adjacent connecting segments. The fabric is produced by a sewing step and a connecting step. The sewing step comprises sewing multiple raw fibers to respectively form the upper layer and the lower layer. The connecting step comprises connecting partially the upper layer to the lower layer by fiber to integrally form the connecting segments and the at least one channel. Thus, time and a cost of a production of the fabric can be reduced to relieve customers' burdens.
