preparation example Construction

[0086] A preparation method of a non-woven material capable of releasing negative ions, comprising the following steps:

[0087] (1) Electret treatment (electret voltage 25-50kV, electret distance 4-8cm) is carried out on the low-melting fiber web (laid directly after spinning, without any rolling and reinforcement), and then pass through the powder The particle applying unit adsorbs the negative ion powder on the low-melting fiber web (the flow rate of the powder is 5-10g / s, and the temperature is 80-120°C) to obtain the low-melting fiber web adsorbed with the negative ion powder; continue to the low-melting fiber The net is rolled;

[0088] (2) performing far-infrared drying treatment at 150-170° C. on the low-melting fiber web adsorbed with negative ion powder particles, so that the low-melting point fibers are melted to fix the negative ion powder particles to make a second fiber layer;

[0089] (3) mixing superabsorbent fibers with antibacterial fibers, and making a firs...

Embodiment 1

[0093] A non-woven material that can release negative ions, the mass per unit area is 60g / m 2 ,like figure 1 As shown, it includes a first fiber layer 1, a second fiber layer 2 and a third fiber layer 3 that are stacked and connected in sequence; the first fiber layer contains superabsorbent fibers and synthetic antibacterial fibers with a water absorption rate of 80 times; The second fiber layer includes low-melting fiber (polypropylene / polyester sheath-core bicomponent fiber filament, skin-core ratio is 30 / 70) and negative ion powder (800 mesh) attached to the low-melting fiber. ); the third fiber layer is a polypropylene spunbond hot-rolled non-woven fabric.

[0094] Wherein, the first fiber layer accounts for 10% of the total mass of the material; the superabsorbent fibers account for 10% of the mass of the first fiber layer; the second fiber layer accounts for 60% of the total mass of the material; the negative ion powder particles It accounts for 20% of the total mass ...

Embodiment 2

[0107] A non-woven material that can release negative ions, the mass per unit area is 120g / m 2 ,like figure 1 As shown, it includes a first fiber layer 1, a second fiber layer 2 and a third fiber layer 3 that are stacked and connected in sequence; the first fiber layer contains superabsorbent fibers and synthetic antibacterial fibers with a water absorption rate of 80 times; The second fiber layer includes low-melting fiber (polypropylene / polyester sheath-core bicomponent fiber filament, skin-core ratio is 50 / 50) and negative ion powder (1200 mesh) attached to the low-melting fiber. ); the third fiber layer is a polypropylene spunbond hot-rolled non-woven fabric.

[0108] Wherein, the first fiber layer accounts for 30% of the total mass of the material; the superabsorbent fibers account for 35% of the mass of the first fiber layer; the second fiber layer accounts for 50% of the total mass of the material; the negative ion powder particles It accounts for 15% of the total mas...

Abstract

The invention relates to the field of non-woven materials, and discloses a non-woven material capable of releasing negative ions and a preparation method thereof.The non-woven material comprises a first fiber layer, a second fiber layer and a third fiber layer which are sequentially connected in an overlapped mode; the first fiber layer contains super absorbent fibers and antibacterial fibers; the second fiber layer comprises low-melting-point fibers and negative ion powder particles; the third fiber layer is composed of hydrophobic fibers. The negative ion powder particles are fixed in the fiber net, the addition amount of the negative ion powder particles is high, and the negative ion powder particles are not prone to falling off; the super-absorbent fibers are arranged in the first fiber layer connected with the negative ion powder particles and used for fully absorbing moisture in the surrounding environment, the negative ion generation amount can be effectively increased, and the air purification effect is improved; antibacterial fibers are added into the first fiber layer, so that the material is prevented from mildewing under the condition that the first fiber layer has high humidity; the non-woven material production device capable of releasing the negative ions is reasonable in design, simple in structure, convenient to operate, high in production efficiency and suitable for actual popularization.

Description

technical field [0001] The invention relates to the field of non-woven materials, in particular to a non-woven material capable of releasing negative ions and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, people are more and more concerned about life, health and safety. In recent years, the number of various types of cancer patients has continued to increase, and people have also put forward new requirements for the safety of various soft decorative materials, which should not only have various special functions, but also have the characteristics of health and environmental protection. [0003] At present, some interior decoration materials for indoor and vehicle use contain a large amount of polymer materials. In daily life, small molecule toxic gases (such as benzene, formaldehyde, acetone, etc.) in these interior decoration materials will be gradually released, imperceptibly endangering people's physical an...
