Problems solved by technology

For example, the patent document CN103991261A discloses a kind of energy resonance cloth. One side of the semi-finished color cloth is coated with a pasty energy resin layer formed by magnetite synthetic powder, oil, water, and resin organic solvent. After the energy resin layer contacts the human body, it absorbs The heat energy of the human body is converted into a specific waveband to achieve the purpose of promoting blood circulation and activating cells, but such energy resonance cloth cannot reach the medical level
Another example is the patent document CN10796445A, which discloses a magnetic coating adhesive and its manufacturing method. The coating adhesive includes adhesive, magnetic powder, filler, diluent, conditioning agent, and the adhesive is a mixture of water-based polyurethane and polyacrylate emulsion. , Such a coating glue is coated on the cloth, etc., which can provide a constant magnetic field around the object and promote the growth and development of the human body or animals and plants. However, the dispersion of magnetic powder in the water-based adhesive is poor, and uneven distribution may occur. Phenomenon

Embodiment 1

[0051] (1) Prepare base fabric: PET / PU knitted fabric

[0052] (2) Configure magnetic coating resin processing fluid:

[0053] 30 parts by weight of solvent-based polyester PU resin

[0054] Permanent magnet material (Nd-Fe-B-Pr, 90% particle size less than 40um) 70 parts by weight

[0055] 20 parts by weight of toluene

[0056] Use a vacuum mixer to mix the components evenly, and obtain a magnetic coating resin after degassing by a vacuum degassing machine;

[0057] (3) On the coating machine, apply the above-mentioned magnetic coating resin processing fluid on the prepared base fabric by scraping; minutes; the second heating temperature is 130°C, and the curing time is 1.5 minutes;

[0058] (4) cooling to obtain the magnetic textile of the present invention. The performance parameters of the obtained textiles are shown in Table 1.

Embodiment 2

[0060] The solvent-based polyester PU resin was replaced by the solvent-based polyether PU resin, and the rest was the same as in Example 1 to obtain the magnetic textile of the present invention. The performance parameters of the obtained textiles are shown in Table 1.

Embodiment 3

[0062] The composition of magnetic coating resin processing fluid is as follows:

[0063] 20 parts by weight of polyester type PU resin

[0064] Permanent magnet material (Nd-Fe-B-Pr) 70 parts by weight

[0065] Softener (polyester modified silicone) 10 parts by weight

[0066] 20 parts by weight of toluene

[0067] Two heating and curing processes, the first heating temperature is 110°C, the curing time is 1 minute; the second heating temperature is 150°C, the curing time is 1 minute heating and curing, and the rest is the same as in Example 1 to obtain the magnetic textile of the present invention. The performance parameters of the obtained textiles are shown in Table 1.

Abstract

The invention discloses a magnetic textile which comprises a base cloth layer and an elastic resin layer. The elastic resin layer contains solvent type polyurethane resin and permanent magnet materials, and metal elements in the permanent magnet materials include one or more of iron, boron, cobalt, neodymium, samarium and praseodymium. The textile has permanent high magnetic density magnetic therapy performances, is soft in hand feeling and further has a waterproof performance.

Description

technical field [0001] The invention relates to a magnetic textile, in particular to a magnetic textile obtained by coating. Background technique [0002] With the progress of society, the continuous research and development of new textile materials, and the continuous improvement of technological conditions, the functionality of textiles has become more abundant and comprehensive. Such as, anti-ultraviolet radiation, antistatic, antibacterial and deodorant, whitening and health care and other effects. [0003] Wearable products for medical and health purposes are also gradually being valued by people. This is because some people do not have much physical activity and labor intensity, but due to incorrect posture, the spine is in a semi-curved state, and the muscles of the back and back are always tense. Nerve endings cause pain, so low back pain occurs; or some people, especially urban white-collar workers, maintain a fixed sitting posture for a long time, and muscles c...
