Description

Technical Field

[0001] The invention relates to the technical field of fabric coatings, and more particularly to a fabric coating with physiotherapy effects and a preparation method thereof. Background Art

[0002] In recent years, with the improvement of people's health awareness, the demand for physiotherapy products in daily life has gradually increased. Although traditional physiotherapy methods, such as massage, hot compress, and drug therapy, can relieve physical discomfort to a certain extent, they are often unable to meet the convenience needs in daily life due to cumbersome operations or reliance on external equipment. Therefore, products that are convenient, comfortable, and can continuously provide physiotherapy performance have become the focus of people's attention.

[0003] Among them, fabrics with physiotherapy effects, as emerging products, have gradually attracted widespread attention. By coating or embedding materials with special physiotherapy functions on the surface of fabrics, physical, chemical or biological effects on the human body can be achieved, thereby providing continuous physiotherapy effects. As the main material of human clothing, fabrics themselves are ideal carriers of physiotherapy products due to their comfort, breathability and ease of wear. Especially with the combination of massage, heat therapy, far infrared, negative ions and other technologies, fabrics can directly contact the skin, and long-term wearing can easily transmit the physiotherapy effects directly to the human body.

[0004] Most existing physiotherapy fabric coatings achieve physiotherapy effects by adding specific functional materials (such as far-infrared ceramic powder). However, the compatibility of far-infrared ceramic powder with other components is poor, resulting in poor stability of the fabric coating structure, which in turn leads to unstable physiotherapy effects. At the same time, the physiotherapy effect is single, mainly physical therapeutic effect, resulting in unclear physiotherapy effects. Therefore, the present invention provides a fabric coating with physiotherapy effects and a preparation method thereof, which can not only enhance the physiotherapy effect of the fabric, but also improve the comfort, durability and ease of use of the fabric, meet people's needs for health care in daily life, and have broad market prospects.

[0149] The comprehensive properties of the fabric coatings obtained in Examples 1-3 of the present invention and Comparative Examples 1-5 were tested respectively, and the test results are shown in Table 1 below.

[0150] (1) Irritation test

[0151] According to the relevant requirements of the "Technical Guidelines for the Study of Local Irritation and Hemolysis of Traditional Chinese Medicine Natural Drugs", the skin irritation of the self-heating gel patch was investigated. 45 New Zealand rabbits, half male and half female, were selected and divided into 9 groups. Before attaching the fabric, the rabbit hair on both sides of the spine needed to be removed 24 hours later. After removing the rabbit hair, observe whether there was epidermal damage. The fabrics obtained in Examples 1-3 and Comparative Examples 1-5 and blank fabrics (3cm×3cm) were attached to the skin of the rabbit depilatory area, covered with cellophane and fixed with medical tape. The fabric was removed after 24 hours, and the skin reaction was observed at 1, 24, 48, and 72 hours. According to the scoring criteria of the guidelines: "no erythema" 0 points, "no edema" 0 points, "non-irritation" 0-0.49 points.

[0152] As a result, 45 rabbits showed no erythema or edema 24 hours after being given the fabrics obtained in Examples 1-3 and Comparative Examples 1-5 and the blank fabric, and the total score was 0, indicating that the fabric coating was non-irritating; it met the standards of the 2020 edition of the Chinese Pharmacopoeia.

[0153] ② Take the fabric coatings (3cm×3cm) obtained in Examples 1-3 and Comparative Examples 1-5 and soak them in pure water for 1 hour, then drip the soaking solution (0.1mL) into one conjunctival sac of the rabbit as the test eye, and drip an equal amount of physiological saline into the other eye as the control eye. After dripping, the eye was passively closed for a period of time, and the eye condition was observed at 1, 24, 48, and 72 hours; during the observation, sodium fluorescein was used to check corneal damage, and a slit lamp was used to check corneal transparency and iris texture changes.

[0154] Results: After 72 hours of immersion, no corneal damage was found in the eyes of 45 rabbits. The cornea was transparent and the iris texture was unchanged, indicating that the fabric coating was non-irritating to the eyes.

[0155] (2) Mouse ear swelling model test to evaluate drug efficacy

[0156] Modeling of xylene-induced ear swelling in mice: 100 μL of xylene (50 μL / surface) was applied to the right ear of the mouse, and the left ear was left untreated. 30 minutes after the inflammation, the thickness of both ears of the mouse was measured, and the mouse was killed by dislocating the neck. An 8 mm puncher was used to punch ear discs at the same position of the left and right ears, and the mass of the ear discs was weighed to calculate the degree of ear swelling.

[0157] The mouse auricle swelling model was divided into 9 groups: model group, experimental group (Examples 1-3 and Comparative Examples 1-5). After xylene was applied to induce inflammation, except for the model group which was not treated, the other 8 groups were immediately attached with the fabrics obtained from Examples 1-3 and Comparative Examples 1-5. After 30 minutes, the thickness of both ears of the mice was measured, the mice were killed by dislocating the neck, and ear discs were punched at the same position of the left and right ears with an 8mm puncher, the mass of the ear discs was weighed, and the ear swelling degree and swelling inhibition rate were calculated.

[0158] SPSS 23.0 statistical software was used for analysis. The measurement data were expressed as mean (x) ± standard deviation (s). The single-sample t-test was used for comparison between the two groups, and One-Way ANOVA was used for comparison between multiple groups. P < 0.05 was considered statistically significant.

[0160] Swelling degree / mg Swelling inhibition rate / % Example 1 13.515±2.057* 55.76 Example 2 11.233±1.768* 59.65 Example 3 12.215±2.154* 57.84 Comparative Example 1 16.235±3.257* 48.23 Comparative Example 2 17.424±2.892* 50.15 Comparative Example 3 18.698±1.347* 44.23 Comparative Example 4 19.424±2.192* 43.15 Comparative Example 5 22.094±3.013* 38.64 Model Group 26.467±3.014 -

[0161] Note: Compared with the model group, *P<0.05.

[0162] From the data shown in Table 1 above, it can be seen that the fabric coatings obtained in Examples 1-3 have a significant therapeutic effect on the mouse auricle swelling inflammation model compared with Comparative Examples 1-5, and the inhibition rate of mouse auricle swelling is higher, which fully demonstrates that the fabric coating of the present invention has the dual effects of medical and physical therapy, and can achieve the therapeutic effects of anti-inflammatory, analgesic, and blood circulation.

[0163] Comparing Example 1 with Comparative Examples 1 and 2, it is fully demonstrated that the addition of lactic acid and acrylic acid to the hydrogel matrix of the present invention is beneficial to increasing the cross-linking density inside the fabric coating, and helps to better load the ionic liquid-far-infrared ceramic powder and the traditional Chinese medicine ingredients in the fabric coating, thereby enhancing the therapeutic effect of the fabric coating.

[0164] Comparing Example 1 with Comparative Examples 3 and 4, it is fully demonstrated that the present invention uses a mercaptosilane coupling agent obtained by mixing 3-mercaptopropyltriethoxysilane and 3-mercaptomethyltrimethoxysilane to modify the far-infrared ceramic powder, which can improve the roughness of the powder surface, thereby increasing the specific surface area of ​​the ionic liquid-far-infrared ceramic powder, thereby improving the compatibility between the ionic liquid-far-infrared ceramic powder and other components, and enhancing the comprehensive performance of the fabric coating.

[0165] Comparing Example 1 with Comparative Example 5, it is fully demonstrated that the ionic liquid of the present invention and the far-infrared ceramic powder are chemically bonded to obtain the ionic liquid-far-infrared ceramic powder, which can enhance the stability of the fabric coating, enhance the affinity of the active ingredients with the skin, and achieve a sustained therapeutic effect.
