Description

Technical Field

[0001] The utility model relates to the technical field of sofa fabrics, in particular to an anti-static sofa fabric. Background Art

[0002] Sofa fabric is a general term or abbreviation for the textile fabric used in the manufacture of various sofas. It directly affects the appearance, feel, and durability of a sofa. Sofa fabric can be divided into various types based on their material and intended use, each with its own unique characteristics, advantages, and disadvantages. Antistatic sofa fabric has an antistatic effect, which can reduce or eliminate the effects of static electricity on sofa use. However, existing antistatic sofa fabrics have poor puncture resistance and are easily punctured by sharp objects when used as sofa coverings. They also provide poor protection for the sofa's internal filling, shortening the sofa's service life. Therefore, the present utility model provides an antistatic sofa fabric. Utility Model Content

[0011] The puncture-proof composite yarn comprises a core wire and a wrapping wire spirally wound around the core wire. The core wire is a spandex filament, and the wrapping wire is an antibacterial ultra-high molecular weight polyethylene fiber yarn.

[0012] On the basis of the above solution and as a preferred solution of the above solution, the spandex filament is an antibacterial spandex filament.
