Description

Bedding fabric having protruding hairs}

The present invention relates to a bedding fabric in which the ridges are formed, and more preferably, to a bedding fabric in which the ridges are formed only on the upper surface.

In modern people, many adult diseases such as high blood pressure, arteriosclerosis, and hypotension are caused by overwork, smoking, stress and lack of exercise, and it is known that taking a good night's sleep is the most suitable method for relieving such fatigue.

Beddings, such as blankets, mattresses, and pillows, are devices in which users lie down to sleep or take a break for about 8 hours, so it is required to provide a function to take a sufficient rest.

As bedding fabrics are in direct contact with the user's skin, a soft touch is required and aesthetics must be considered. Therefore, a variety of colors and patterns are formed on the surface using soft fabrics. In addition, the bedding fabric has a direct important effect on health since it comes into direct contact with the user's skin.

Therefore, various studies have been conducted on the fabric for bedding, but the user's satisfaction does not seem to be high enough. For example, some people use a towel wrapped around a pillow, or sleep with a towel over their mattress. This behavior seems to indirectly explain the shortcomings of bedding fabrics. Therefore, it is required to develop various types of bedding fabrics by accurately grasping the user's needs for bedding fabrics.
