Description

TECHNICAL FIELD

[0001] The present application relates to a shape memory massage warm-keeping knee pad and a preparation method thereof, and belongs to the field of textiles. BACKGROUND

[0002] The knee joint is a key part of the human body during movement. A warm-keeping knee pad can protect the knee joint and prevent cold, thereby reducing joint diseases caused by cold and dampness.

[0003] Existing warm-keeping knee pads are mainly divided into two categories. The first category is a cylindrical warm-keeping knee pad, which is relatively close-fitting to the human body, but is relatively tight, difficult to put on and take off, has a large pressure on the human body, and leaves pressure marks after being worn for a period of time. The second category is a warm-keeping knee pad with a binding belt, a hook-and-loop fastener, etc. The binding belt, the hook-and-loop fastener, etc. can be adjusted, and the knee pad is more convenient to wear than the first category. However, the knee pad is composed of accessories and a main body, and cannot be well fitted to the human body, which affects the wearing comfort. In summary, the two categories of existing warm-keeping knee pads cannot simultaneously satisfy the convenience of putting on and taking off and the better wearing comfort.

[0004] On the basis of the warm-keeping knee pad, the massage function is added, which can better meet the health care needs. The current warm-keeping massage knee pad mainly has air bag massage, vibration massage, point pressure massage, etc. The air bag, vibration motor, and massage pad for realizing the massage function are not easy to take out and separate, which is cumbersome in the use scenario where only the warm-keeping function is needed without the massage function, affects the wearing experience, and has insufficient functional flexibility. SUMMARY

[0005]

Technical problem

[0006] The existing warm-keeping knee pad is fitted and fixed to the human body by using high-elasticity fibers and adding a binding belt, a hook-and-loop fastener, etc., but also causes inconvenience in putting on and taking off the knee pad. Moreover, the existing warm-keeping knee pad cannot have the function of massaging the knee joint while keeping warm.

[0007]

Technical solution

[0008] In order to solve the above problems, the present application provides a shape memory massage warm knee pad and a preparation method, which adopts shape memory spandex covering yarn, ordinary spandex covering yarn, wool yarn and conductive yarn as raw materials to weave the shape memory massage warm knee pad. The finished product is in the shape of a cylinder, integrally formed without edge seams, and has an air layer structure. Only one side of the massage part is woven by shape memory spandex yarn and conductive yarn. Before wearing, the shape memory characteristic can be used to stretch and adjust the knee pad to a suitable size and fix it. After wearing, the shape memory spandex restores elasticity under the stimulation of human body surface temperature or electric heating. The side with shape memory spandex in the massage part shrinks, and the other side arches, thereby forming regular concave-convex patterns according to the pattern, providing massage effect for the knee and providing appropriate pressure to fit the human body without leaving pressure marks. The shape memory spandex has weak restoring force below room temperature (25℃), and shows weak resilience. At the same time, the spandex yarn deformation (stretched length) can be fixed to a certain extent under this temperature condition, and will not immediately restore to the shape (length) before stretching. When the temperature of the shape memory spandex itself is higher than the switching temperature (26℃), it will restore to the shape (length) before stretching in a short time and restore elasticity, and the restoring force is improved. The human body surface temperature is about 34℃, which is higher than the switching temperature, and can trigger the shape memory function. Therefore, this kind of fiber is suitable for application in the field of textiles and clothing.

[0058] Advantages of the present application:

[0059] (1) The knee protector prepared by the present application adopts shape memory spandex covering yarn as raw material. Shape memory spandex takes 26℃, which is lower than the body surface temperature of human body (34℃), as switching temperature. When the temperature is lower than the switching temperature, the knee protector can fix the deformation to a certain extent, and when the temperature is higher than the switching temperature, the deformation is recovered. That is, before wearing the shape memory spandex warm knee protector, the knee protector can be stretched to a size convenient for wearing, and after wearing, the knee protector automatically recovers the shape, fits the human body, and cooperates with wool yarn, solves the problem that the cylindrical knee protector is not easy to put on and take off, and has the functions of keeping warm.

[0060] (2) The knee protector prepared by the present application is knitted with air layer tissue with regular patterns in a certain area, wherein only one side adopts shape memory spandex covering yarn, and the other side adopts ordinary spandex covering yarn. By using the temperature-sensitive shape memory characteristics of shape memory spandex, after wearing on the upper body, with the increase of temperature, the shape memory spandex elastically recovers and shrinks, and the other side is arched accordingly, cooperates with the pattern, forms regular concave-convex, and has the massage effect when wearing.

[0061] (3) The knee protector prepared by the present application knits the shape memory spandex covering yarn and the conductive yarn in the massage area at the same time, and connects them with the temperature controller and the rechargeable battery. When the temperature control switch is turned on, the conductive yarn generates heat after being electrified, stimulates the shape memory spandex to shrink, forms the concave-convex massage effect, and meets the use needs when the temperature is lower than the switching temperature.

[0062] (4) The shape memory massage warm knee protector of the present application prepares knee protectors with different shape memory spandex content by changing the specifications and the number of wearing yarns of shape memory spandex covering yarn, ordinary spandex covering yarn and wool yarn.
