Description

Technical Field

[0001] The invention relates to the technical field of textiles, and in particular to a woven four-sided stretch integrated velvet fabric and a production method thereof. Background Art

[0002] The polar fleece fabrics currently on the market are generally knitted fabrics with small ingot structures. They are woven by circular knitting machines and combined with dyeing and napping technology to form products that are not easy to shed and pilling, and have particularly excellent thermal insulation performance. However, due to the coil structure of knitted polar fleece, it has good tensile properties, poor recovery properties, and the fabric is easy to deform. Moreover, the knitted fabric structure has large gaps and high air permeability, and generally requires double-sided napping and polarizing treatment, which is expensive. In order to improve the thermal insulation performance of polar fleece fabrics, glue and other fabrics of different styles are mainly used at this stage. This increases production costs and processes, and the loss of laminated fabrics is large, which is not environmentally friendly. Glue will cause certain harm to consumers' physical and mental health. After repeated washing, there is a risk of peeling of laminated fabrics. Summary of the invention
