Abstract
The invention discloses an intelligent medical temperature-sensitive fabric which comprises a flexible conductive fiber layer, a breathable layer, an antibacterial layer and a warm-keeping layer, wherein the flexible conductive fiber layer, the breathable layer, the antibacterial layer and the warm-keeping layer are sequentially arranged from top to bottom, the warm-keeping layer is formed by weaving a textile fabric after padding treatment by a temperature-sensitive microcapsule finishing agent, and the antibacterial layer is formed by weaving flax fibers after dipping treatment by a composite essential oil fabric finishing agent. According to the invention, the flexible conductive fiber layer, the antibacterial layer and the heat-preservation layer are combined into the traditional fabric, so that the fabric has the functions of medical temperature monitoring and temperature sensing and heat preservation, has excellent air permeability and long-acting antibacterial property, is comfortable to wear, and when the temperature is lower than UCST in winter, the core material with the natural heat-preservation and health-care functions is slowly released, so that the heat preservation and heat preservation are effectively realized for a human body, and when the temperature reaches the proper temperature, the core material release channel is closed, so that the medical intelligent temperature sensing regulation and control are realized.
Description
Technical Field
The invention relates to the field of intelligent materials, in particular to an intelligent fabric.
Background
With the development of economy, the acceleration of the rhythm of people and the increase of working pressure, people pay more and more attention to the health condition of people and have higher and more higher requirements on the quality and the function of clothes and fabrics for medical treatment. However, the fabric on the market has high cost, heavy weight and poor air permeability, affects the comfort of the fabric in use, has poor antibacterial performance, has single functionality, does not have intelligent heat preservation or temperature sensing effect, does not have electrical sensing test function, and cannot sense the body temperature or physiological state change on the surface of a human body.
In the prior art, attempts have been made to adopt fabrics as substrates, utilize conductive yarns to be woven into clothes in a weft or warp mode, or utilize conductive fabrics to be sewn on clothes, use conductive yarns as internal connecting lines of the clothes, and adopt electronic fabrics manufactured in various modes, which are an important development direction of intelligent medical fabrics. In addition, the thermosensitive polymer is an important intelligent material and can respond to temperature change. The thermosensitive materials may be classified into two major types, i.e., having a high critical phase transition temperature (UCST) and having a lowest critical phase transition temperature (LCST), according to the characteristics of the critical phase transition temperature. Most UCST polymers are amphoteric polymers or amphoteric polyelectrolytes, and due to the unique molecular structure, the structure and the characteristics of the material can be controlled by using the change of environmental temperature. However, there is still no intelligent fabric which has both functions of medical temperature monitoring and temperature sensing and warming.
Disclosure of Invention
The invention aims to provide an intelligent medical temperature sensing fabric aiming at the defects of the prior art.
The technical scheme adopted by the invention is as follows: an intelligent medical temperature-sensitive fabric comprises a flexible conductive fiber layer, a breathable layer, an antibacterial layer and a warm-keeping layer which are sequentially arranged from top to bottom, wherein the warm-keeping layer is formed by weaving textile fabrics after padding treatment by a temperature-sensitive microcapsule finishing agent, and the antibacterial layer is formed by weaving flax fibers after dipping treatment by a composite essential oil fabric finishing agent.
Specifically, the flexible conductive fibers are introduced into the fabric layer structure to serve as the temperature sensor, so that the temperature sensor can be used for monitoring the motion state of a human body and the change of the body surface temperature. Meanwhile, the fabric is endowed with the effects of lasting warm keeping and health care by introducing the special warm keeping layer which is subjected to padding treatment by the temperature-sensitive microcapsule finishing agent.
As a further improvement of the scheme, the temperature-sensitive microcapsule finishing agent comprises the following components in parts by weight: 0.1-1 part of temperature-sensitive material, 0.5-3 parts of natural polymer material, 1-2 parts of pomegranate essential oil, 1-2 parts of benzoin essential oil and 0.1-0.5 part of propolis. Specifically, the temperature-sensitive microcapsule finishing agent is prepared by adding a natural high polymer material, pomegranate essential oil and benzoin essential oil into water, uniformly stirring at 45-50 ℃, adding a temperature-sensitive material and a curing agent, curing at room temperature for 2-3 hours, standing, filtering and drying.
As a further improvement of the scheme, the temperature-sensitive material is amphoteric polyelectrolyte with sulfonate and ammonium groups, the isoelectric point is 4.0-4.2, and the high critical phase transition temperature UCST is 18-23 ℃.
As a further improvement of the scheme, the natural polymer material is selected from one of carrageenan, xanthan gum, sodium alginate and chitosan.
The composite essential oil fabric finishing agent comprises, by weight, 2-5 parts of basil essential oil, 2-5 parts of geranium essential oil, 2-5 parts of ginseng essential oil, 2-5 parts of citronella essential oil, 2-5 parts of agilawood essential oil, 10-20 parts of β -cyclodextrin aqueous solution, 1-3 parts of emulsifier and 5-10 parts of chitosan, and specifically, the composite essential oil plant finishing agent is prepared by uniformly mixing basil essential oil, geranium essential oil, ginseng essential oil, citronella essential oil, agilawood essential oil and β -cyclodextrin aqueous solution, adding the emulsifier, uniformly mixing, reacting for 1-2 hours, adding the chitosan, and completely reacting.
As a further improvement of the above aspect, the textile fabric is selected from one of cotton, wool, cashmere, kapok, lyocell, and modal.
As a further improvement of the scheme, the air permeable layer is uniformly provided with small needling holes, and the aperture of each small needling hole is 1-5 nm.
