Embodiment approach

[0017] B. Dilute and mix the wave-absorbing agent and the flexible adhesive evenly to make a wave-absorbing adhesive with good bonding properties. The mass percentage of the wave-absorbing agent is 1% to 5%, and the mass percentage of the flexible adhesive is The content is 95% to 99%;

[0018] C. Immerse the plush of the single-sided suede fabric prepared in step A in the wave-absorbing adhesive prepared in step B, and the immersion time is 2h to 5h;

[0019] D. Padding the suede fabric obtained in the previous step with a pressure of 0.2-0.4MPA to squeeze out excess wave-absorbing adhesive;

[0020] E. Bake the suede fabric obtained in the previous step in an oven at 120-180° C. for 2-4 minutes to make a suede-structured broadband electromagnetic wave-absorbing fabric.

[0021] The fluff shape of the fabric is vertical, circle, ball, rose, chrysanthemum; the absorber is carbon black.

[0022] like figure 1 as shown, figure 1 It is the absorbing loss curve of the broadb...

Abstract

The invention discloses a processing method of a wideband electromagnetic wave absorption suede fabric. The processing method comprises the following steps: weaving a dual-layer fabric by selecting and using conductive fiber blended yarns; diluting and uniformly mixing a wave absorbent with a flexible adhesive to prepare a wave absorption adhesive with good adhesion performance; soaking plush of a prepared one-sided suede fabric in the prepared wave absorption adhesive; performing pad-roll on the obtained suede fabric by a proper pressure and removing the excess wave absorption adhesive by extruding; baking the obtained suede fabric in a baking oven to prepare the special wideband electromagnetic wave absorption suede fabric. The wideband electromagnetic wave absorption suede fabric has the absorbed electromagnetic wave frequency range of 300 MHz to 40 GHz, can serve as an important biological health protection or facility safety protection product, and radically eliminates the harm caused by electromagnetic radiation.

Description

technical field [0001] The invention relates to a method for processing fabrics with a suede structure. The fabrics can absorb broadband electromagnetic waves and belong to textile materials. Background technique [0002] When people apply electromagnetic wave technology to various aspects of military affairs, production, and life, and when people enjoy the convenience brought by the application of various electronic products, electromagnetic radiation also brings safety problems at the same time. Electromagnetic radiation is the fourth largest pollution after air pollution, water pollution and noise pollution. The World Health Organization believes that electromagnetic radiation has become a serious problem affecting public health in today's world. In addition, electromagnetic radiation also causes serious harm to the safe operation of electrical equipment. [0003] At present, the textiles that prevent electromagnetic radiation mainly include blended fabrics of metal wir...
