Problems solved by technology

At present, there are three methods used: one is to use conductive metal wires directly embedded in the fabric in a grid shape, but the deformation of the metal wires is extremely small, which seriously affects the deformation of clothing and wearing comfort; and the electromagnetic shielding is affected by the conduction of the metal wires. It depends on the amount of metal wire added; the second is the core-spun yarn of metal wire to avoid mutual conduction, increase dielectric loss and electromagnetic shielding, but most of them are made into composite spinning with other fiber twists, which is still Mutual conduction, although the elasticity of the yarn increases, the electromagnetic shielding performance is still dominated by the content of the metal wire, and the wearing comfort is also deteriorated; the third is to use metal fiber spinning, although the wearing fit is improved, but the contact Very poor comfort, itching, even tingling, and electromagnetic shielding depends on the content of metal fibers

Embodiment 1

[0024] Embodiment 1: the production equipment of electromagnetic shielding yarn:

[0025] Such as figure 1 As shown, it is a top view of the production equipment of electromagnetic shielding yarn, figure 2 In its side view, the electromagnetic shielding yarn production equipment includes a ring spinning frame, and also includes a tension wheel 1 , a holding roller 2 , a yarn guide hook 3 and a cluster 4 . The grip roller 2 is in contact with the front roller 11 of the ring spinning frame, and is driven by the rotation of the front roller 11 . The tension wheel 1 is installed on the ring spinning frame at a position above the holding roller 2, and the yarn guide hook 3 and the bundler 4 are located behind the front roller nip 10 of the ring spinning frame.

[0026] When in use, take an elastic filament tube, pass the elastic filament 5 on it through the tension wheel 1 with a certain tension, and then directly pass the holding roller 2 with a certain angle of envelopment o...

Embodiment 2～7

[0027] Embodiment 2~7: Electromagnetic shielding yarn and production method thereof:

[0028]Adopt the production equipment of the electromagnetic shielding yarn described in embodiment 1, the staple fiber strip 7 is fed into the front roller nip 10 through the bundler 4, and the metal wire 6 is fed into the front roller nip 10 through the yarn guide hook 3, so that The metal wire 6 described above is located on the central axis of the short fiber strand 7, and the short fiber strand 7 and the metal wire 6 are combined on the outside of the front roller jaw 10 to form a covered yarn segment that the short fiber strand 7 coats the metal wire 6 8. After the elastic yarn 5 passes through the tension wheel 1 and the holding roller 2, it is attached to the front roller 11 and fed into the front roller nip 10, and the covered yarn segment 8 and the elastic yarn 5 exiting the front roller nip 10 are twisted Under the action, the electromagnetic shielding yarn in which the covering ...

Embodiment 2

[0034] One stainless steel wire tube, one spandex filament cake and one cotton short fiber roving tube are used, and the three-axis composite spinning is carried out according to the above composite spinning method. The specific process parameters are shown in the table below. The electromagnetic shielding yarn of the spun cotton fiber coated stainless steel wire and then outsourced spandex yarn, its covering rate, twist angle characteristics, electrical insulation, comfort and elasticity are listed in Table 1. This demonstrates the fact that the surface rigid fibers are transformed into elastic yarns.

Abstract

The invention provides an electromagnetic shielding yarn with metal wire wrapping elastic yarn and its production equipment and production method. The electromagnetic shielding yarn is characterized in that it includes an elastic yarn, and a covered yarn segment is wound outside the elastic yarn, and the covered yarn segment includes a metal wire and short fiber strands wrapped on the outer side of the metal wire. Its production equipment includes a ring spinning machine, which is characterized in that it also includes a tension wheel, a holding roller, a yarn guide hook and a cluster. The invention can be made into a composite yarn which not only has better extensibility and elasticity but also has the function of electromagnetic shielding. The resulting electromagnetic shielding yarns can be used in the production of general clothing and textiles for home and industrial use.

Description

technical field [0001] The invention relates to an electromagnetic shielding yarn with elastic yarn wrapped with metal wires and its production equipment and production method, belonging to the technical field of ring spinning. Background technique [0002] In today's unavoidable electromagnetic radiation, even harmful, wearing clothing with electromagnetic shielding and setting up light-weight protective barriers is a negative way, but it is effective and practical. The basis for this realization is textile materials, i.e. fibers, yarns and their products. At present, there are three methods used: one is to use conductive metal wires directly embedded in the fabric in a grid shape, but the deformation of the metal wires is extremely small, which seriously affects the deformation of clothing and wearing comfort; and the electromagnetic shielding is affected by the conduction of the metal wires. It depends on the amount of metal wire added; the second is the core-spun yarn o...
