Embodiment 1

[0026] Example 1: Production equipment for wave-absorbing high-elastic yarn

[0027] Such as figure 1 As shown, it is a top view of the production equipment of wave-absorbing high-elastic yarn, figure 2 As a side view, the production equipment of the wave-absorbing high-elastic yarn includes a ring spinning frame, an elastic yarn tension disc 1, an elastic yarn holding roller 2, a metal wire tension disc 3, a metal wire holding roller 4, and short fiber Bell mouth 5 and the rear bell mouth 6 of short fiber whiskers before the strips. Both the elastic yarn gripping roller 2 and the metal wire gripping roller 4 are in contact with the front roller 13 of the ring spinning frame, and are driven by the rotation of the front roller 13 . The elastic wire tension disk 1 is arranged above the elastic wire holding roller 2 , and the wire tension disk 3 is arranged above the metal wire holding roller 4 . The front bell mouth 5 of the short fiber sliver is aligned with the rear bell m...

Embodiment 2-7

[0029] Embodiment 2-7: wave-absorbing high elastic yarn and production method thereof:

[0030] Adopt the production equipment of the wave-absorbing high-elastic yarn described in embodiment 1, the metal wire 8 and the elastic wire 7 are fed into the front roller nip 12 synchronously after passing the metal wire holding roller 4 and the elastic wire holding roller 2 respectively; at the same time, Make the staple fiber strands 9 drawn by the back roller 15, the middle roller 14 and the front roller 13 of the ring spinning machine fed through the short fiber strands rear bell mouth 6 through the staple fiber strands front bell mouth 5 feeding Enter the front roller nip 12 to form a three-axis feeding system. After the front roller nip 12 is output, at the first convergence point A, the metal wire 8 is wound by short fiber strands 9 to form a core-spun structure yarn section 10, and then At the second converging point B, the core-spun yarn section 10 is spirally wound outsid...

Embodiment 2

[0034] Using one stainless steel wire tube, one spandex filament cake and one cotton staple fiber roving tube, carry out the composite spinning with three shafts and two converging points according to the above composite spinning method, and the specific process parameters are shown in the table below. After the spun cotton fiber is coated with stainless steel wire, the wave-absorbing high-elastic yarn of spandex yarn is outsourced. The covering rate, twist angle characteristics, electrical insulation, comfort and elasticity are listed in Table 1. This is the fact that the superficially rigid fibers are transformed into elastic yarns.

Abstract

The invention relates to a wave-absorbing high-elasticity yarn and production equipment and a production method thereof. The wave-absorbing high-elasticity yarn is characterized in that the wave-absorbing high-elasticity yarn comprises an elastic yarn, a core-spun structural yarn section is wound on the external side of the elastic yarn, and the core-spun structural yarn section comprises a metal wire and a staple strand which is wound on the external side of the metal wire. The production equipment of the wave-absorbing high-elasticity yarn comprises a ring spinning machine and is characterized in that the equipment additionally comprises an elastic yarn tension disc, an elastic yarn holding roll, a metal wire tension disc, a metal wire holding roll, a staple strand front bell mouth and a staple strand rear bell mouth. Only by adding a pair of tension plates, two holding rolls and two bell mouths on a common spinning machine, the high-elasticity composite spinning of the non-elastic metal wire can be realized. Therefore, the method is simple and practical.

Description

technical field [0001] The invention relates to a wave-absorbing high-elastic yarn combined at two points of metal wire and elastic yarn, as well as 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 ...
