Description

Technical Field

[0001] The utility model belongs to the technical field of textile fibers, in particular to a mixed raw material modified monofilament. Background Art

[0002] Polyurethane elastic fiber, also known as spandex, is a highly elastic textile fiber with a breaking elongation of generally 500% to 700%, high breaking strength and large elastic recovery rate. Therefore, spandex fiber is widely used in fabrics. It provides people with a variety of textile fabrics by interweaving or interweaving with other fibers.

[0003] However, the existing polyurethane elastic fibers still have defects to a certain extent. Therefore, we propose an improvement. Utility Model Content

[0004] The utility model aims to provide a mixed raw material modified monofilament, which has better elasticity and bending and fracture resistance performance when used compared with the existing polyurethane elastic fiber.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model is a mixed raw material modified monofilament, comprising a silk thread, wherein the silk thread is formed by three modified silk threads interwoven and wound into a spiral structure with a gap in the middle;

[0007] The modified yarn is formed by melt mixing and extrusion of polyester elastomer and polyurethane;

[0008] The outer wall of the modified wire is integrally formed with protrusions, and the protrusions are irregularly distributed on the outer wall of the modified wire.

[0009] Further, the protrusion is one of polyester elastomer and polyurethane elastomer. Further, the protrusion is one of semicircular or elliptical.

[0010] Furthermore, an arc-shaped gap is formed between the two protrusions.

[0011] The utility model has the following beneficial effects:

[0012] Through the setting of modified silk and protrusions, three modified silks are interwoven and wound into a spiral structure with a gap in the middle, so that the whole silk thread has good deformation space, thereby improving the elasticity of the textile, and the modified silk is formed by melt mixing and extrusion of polyester elastomer and polyurethane, and its physical properties remain almost unchanged in an environment of minus 30°C to high temperature 150°C; at the same time, it has high folding resistance, the single silk feels flexible, high elasticity, and good recovery rate. The staggered arrangement of protrusions can further increase the elasticity and compressive rebound performance of the silk thread.

[0013] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
