Embodiment 1

[0023] In one embodiment, a novel multi-functional covered yarn, the multi-functional covered yarn includes a core wire 1 and an outer covering wire 2 wrapped around the core wire 1, the outer covering wire 2 It is made of ultra-fine denier nylon 6 yarn with a double 8-shaped structure on the transversely laminated surface, and the core thread 1 is spandex yarn.

[0024] Further, in the double 8-shaped structure, the double 8s are the same central line.

[0025] A preparation method for a novel multifunctional covering yarn, comprising the following steps:

[0026] (1) Preparation of special double-8 cross-section ultra-fine nylon yarn: put the caprolactam chips into the rod extruder for melt extrusion, the melting temperature is 300 °C, pass through the spinning assembly, and then in the hole with a fineness of 0.425 The denier double 8-hole spinneret is sprayed out, and then is blown and cooled by side wind through the spinning tunnel. The air cooling temperature is 22°C, a...

Embodiment 2

[0031] A preparation method for a novel multifunctional covering yarn, comprising the following steps:

[0032] (1) Preparation of special double-8 cross-section ultra-fine nylon yarn: put caprolactam slices into a rod extruder for melt extrusion at a melting temperature of 320°C, pass through the spinning assembly, and then pass through the spinning assembly with a hole fineness of 0.625 The double-denier 8-shaped spinneret is sprayed out, and then passed through the spinning tunnel for side wind blowing and cooling. The air-cooling temperature is 20°C, and it becomes a double-8-shaped nylon yarn;

[0033] (2) Nylon yarn winding; the winding adopts an online tension device with a tension controller, adjust the tension to 3CN±3%, and the winding speed is 800 / min, and then wind the nylon yarn from the nylon bobbin to the bag evenly. on the aluminum-clad bobbin;

[0034] (3) Draw and twist the spandex yarn with nylon yarn with double 8 cross-section. When twisting, the speed of...

Abstract

The invention discloses a novel multifunctional cladding yarn and a preparation method, wherein the multifunctional cladding yarn comprises a core wire and an external cladding wire covering the core wire; the external layer cladding wire is made of a kind of super fine denier nylon 6 yarn with the cross section in a double 8 structure; and the core wire is spandex filament. The yarn is made by the steps of (1) preparing the super fine denier nylon yarn that has a special double 8 structure on the cross section; (2) winding nylon wire, wherein the nylon wire is wound with n on-line tension apparatus with a tension controller; (3) drawing-off and twisting the spandex filament with the nylon yarn that has a double 8 cross section; (4) using a rewinder of the on-line tension to roll the finished product, so as to manufacture a multifunctional cladding yarn. The novel multifunctional cladding yarn prepared by the invention has the advantages of good moisture absorption and rapid drying by reconstructing the yarn surface structure and increasing yarn permeability; increased contact area with skin; soft feeling; tight fabrics; and greatly improved enjoy performance; and it's cool on wearing and the yarn is smooth like the silk.

Description

technical field [0001] The invention relates to a covered yarn and a preparation method thereof, in particular to a novel multifunctional covered yarn and a preparation method thereof. Background technique [0002] With the improvement of people's living standards and the quickening pace of life, people's requirements for clothing are getting higher and higher. Fitting, comfort, softness and elasticity have become the pursuit goals of new clothing fabrics. Therefore, spandex elastic fabric has become a new favorite in clothing. [0003] Spandex covered yarn is one of spandex elastic yarn varieties. The existing common spandex-coated yarn has a circular yarn cross-section, low twist in the process, poor yarn coating effect, and the specific surface area of ​​the yarn in contact with the skin is small, and the air permeability is poor. In summer, it feels stuffy and uncomfortable when wearing the fabric of this yarn. Especially when applied to silk stockings, sports underwe...
