Embodiment 1
Referring to FIG. 1 to FIG. 6, a pillowcase includes:

    
    
        a pillowcase main body 1, wherein the pillowcase main body 1 is made of a fabric; the pillowcase main body 1 includes an upper covering surface 11 and a lower covering surface 12; the upper covering surface 11 is connected to the lower covering surface 12 to form a first accommodating space 2 around the upper covering surface 11 and the lower covering surface 12; the first accommodating space 2 is configured to accommodate a pillow core; the fabric includes a carrier and a care agent; the care agent is mixed with the carrier; and the carrier is composed of spandex and a polyamide fiber. The carrier of the fabric is composed of the polyamide fiber and the spandex. This combination can provide good wear resistance, elasticity, and comfort, so that the pillowcase is more durable and suitable for long-term use. Meanwhile, due to the addition of the care agent, this pillowcase can have a skincare effect.
    
    


In this embodiment, the carrier is formed by interweaving the polyamide fiber with the spandex, so that the fabric has good elasticity, breathability, wear resistance, and creasing resistance.
In this embodiment, the polyamide fiber in the carrier accounts for 60% to 95%, and the spandex accounts for 5% to 40%. The polyamide fiber is a high-strength synthetic fiber. The polyamide fiber in a high ratio can improve the overall strength and wear resistance of the fabric. The spandex has good elasticity, and an appropriate amount of spandex can make the fabric more elastic and improve the comfort of the pillowcase. A small amount of spandex can improve the moisture absorption of the fabric, which helps to keep a surface of the pillowcase dry and comfortable. The polyamide fiber in the high ratio has good creasing resistance, and the spandex in the low ratio makes the fabric easier to care for. This pillowcase is easier to clean and is dried faster, which reduces the cleaning burden on a user.
In this embodiment, the care agent is mixed with the carrier through an immersion method; a liquid pick-up rate is controlled between 60% and 80%; shaping and drying are carried out to mix the care agent with the carrier; and the care agent is added to the carrier according to a ratio of 20 g/L to 50 g/L. Controlling the pick-up rate between 60% and 80% can help adjust the content of the care agent. This can balance the care effect with the comfort of the fabric, avoiding the sticky feel caused by an excessive amount of the care agent. In addition, the shaping and drying process helps to combine the immersed care agent with the carrier, so as to ensure that the care agent and the carrier are fixed in the fabric. This helps to improve the durability of the care agent, keeping the care agent effective within a long time period.
In this embodiment, the pillowcase includes: a front side 13, a rear side 14, a left side 15, a right side 16, an upper side 17, and a lower side 18.

Embodiment 2 and Embodiment 3
In the embodiments shown in FIGS. 7-10 and FIGS. 10-13, the material used for the pillowcase 1 is the same as that in the aforementioned embodiments. The difference lies in that: the pillowcase 1 at least includes an accommodating opening 3 The pillowcase 1 has a first through hole 21 extending from the upper covering surface 11 to the lower covering surface 12. The Pillowcase 1 further includes: an outer cover portion 35 connected between the upper covering surface 11 and the lower covering surface 12, enclosing a periphery of the pillow core; and a connecting member 10 connected between the upper covering surface 11 and lower covering surface 12 and passing through first through hole 21.
The connecting member 10 has an annular cross-section and is circumferentially disposed around a wall surface of first through hole 21. The connecting member 10 further forms a second through hole 22 running from the upper side to the lower side of the pillow.
Specifically:
The first through hole 21 has an inner diameter ranging from 1 cm to 20 cm. The second through hole 22 has an inner diameter ranging from 1 cm to 20 cm. The first through hole 21 has a depth ranging from 3 cm to 15 cm. The second through hole 22 has a depth ranging from 3 cm to 15 cm.
Each of the first through hole 21 and the second through hole 22 may be one of: a circular hole, an elliptical hole, a square hole, a rectangular hole, a diamond-shaped hole, a hexagonal hole, a triangular hole, and a cross-shaped hole.
It is to be understood that: the first through hole 21 has a maximum inner diameter and a minimum inner diameter each independently ranging from 1 cm to 20 cm; the second through hole 22 includes a maximum inner diameter and a minimum inner diameter each independently ranging from 1 cm to 20 cm. This dimensional range ensures optimal ventilation while maintaining sufficient structural support. The depth of the first through hole and the second through hole ranges from 3 cm to 15 cm, which can achieve a favorable ventilation effect while ensuring the required support height.
Additionally, the first through hole 21 and the second through hole 22 can be in various shapes, which can be customized according to actual needs to enhance user experience.
At least one of the upper covering surface 11 and the lower covering surface 12 is detachably connected to the outer cover portion 35 to form a first angle (e.g., via at least one zipper 36 as shown in FIGS. 11-13, or other detachable fasteners such as hook-and-loop straps, buttons as illustrated in FIGS. 7-10, etc.), enabling complete detachment or attachment of an edge of either the upper covering surface 11 or the lower covering surface 12 from/to an edge of the outer cover portion 35.
Specifically, one of the upper covering surface 11 and the lower covering surface 12 is detachably connected to the outer cover portion 35; while the other of the upper covering surface 11 and the lower covering surface 12 is fixedly connected to outer cover portion 35 to form a second angle. This configuration prevents edges of the detachable connection from interfering with a user's head or neck region, thereby ensuring optimal user comfort.
Each of the first angle and the second angle may be, but not limited to a right angle.
The connecting member 10 includes a first connecting member 33 disposed on the upper covering surface 11 and a second connecting member 34 disposed on the lower covering surface 12. The first connecting member 33 is detachably connected to the second connecting member 34 through the first through hole 21, thereby enabling the upper covering surface 11 and the lower covering surface 12 to clamp the pillow core within pillowcase 1.
The first connecting member 33 is disposed on an inner side of the upper covering surface 11, and the second connecting member 34 is disposed on an inner side of the lower covering surface 12. The first connecting member 33 includes a first connection portion 31 and a first connection surface 32. A side of the first connection surface 32 is connected to an inner side of the upper covering surface 11, another side of the first connection surface 32 is connected to the first connection portion 31.
The second connecting member 34 includes a second connection portion 41 and a second connection surface 42. One side of the second connection surface 42 is connected to an inner side of the lower covering surface 12, and another side of the second connection surface 42 is connected to the second connection portion 41. Specifically, the first connection portion 31 is a first connection buckle, the second connection portion 41 is a second connection buckle, and the first connection buckle is detachably connected to the second connection buckle. Through such configurations, the upper covering surface 11 and the first connection surface 32 covers the first connection buckle, the lower covering surface 12 and the second connection surface 42 covers the second connection buckle, so as to hide the first connection buckle and the second connection buckle, which not only makes the pillowcase 1 smoother and more aesthetically pleasing when fitted onto the pillow core, but also effectively prevents users from coming into direct contact with the first connecting buckle and the second connecting buckle during use. This helps to avoid feeling of foreign objects or discomfort in the user's cervical spine, making the pillow more acceptable to users. Furthermore, the first connecting surface 32 is attached to the inner side of the upper covering surface 11 by stitching, and the second connection surface 42 is attached to the inner side of the lower covering surface 12 by stitching.
When the first connecting member 33 is connected to the second connecting member 34 through the first through hole 21, causing the upper covering surface 11 and the lower covering surface 12 to clamp the pillow core within the pillowcase 1, a first gap 7 exists between the upper covering surface 11 and the first through hole 21, and a second gap 8 exists between the lower covering surface 12 and the first through hole 21. The first gap 7, the first through hole 21, and the second gap 8 are interconnected to form a heat dissipation channel. Through this configuration, when a user uses the pillow, heat can be dissipated through the heat dissipation channel, preventing heat from accumulating on the pillow. This allows the user to have a more comfortable sleeping environment, thereby improving the user's sleep quality.
