Abstract

The utility model discloses a high-elasticity pillow case, which comprises an upper pillow sheet and a lower pillow sheet, wherein the lower pillow sheet is made of spandex knitted fabric, and an open-type opening is arranged in the middle of the lower pillow sheet; the utility model provides an adopt spandex knitted fabric's pillowcase has elasticity dynamics height, the difficult loss of elasticity, characteristics that the answer rate is high, puts into the pillowcase with the pillow through the open-type entry that sets up on the pillow piece down more easily, also can prevent to exert oneself too much simultaneously and tear the pillowcase from the opening part, conveniently replaces the pillow, saves time and manpower, is particularly useful for places such as hotel, beauty parlor that need often change the pillow and uses.

Description

High-elasticity pillowcase

Technical Field

The invention belongs to the technical field of bedding, and particularly relates to a high-elasticity pillow case.

Background

Existing pillow cases are usually filled with pillow interiors in the following manner: 1. the back of the pillowcase is provided with two lower pillow sheets which are staggered to form an opening for filling the pillow core, when the pillowcase is used for filling the core, the pillow core must be filled into the pillowcase for a very deep distance, and sometimes the opening can be torn by slight over-force; 2. sewing three edges of the upper pillow piece and the lower pillow piece of the pillow case to form an empty bag, filling the pillow core from one open end, and allowing the pillow core to easily slide out of the pillow case if one side of the long edge of the pillow case is reserved; if one side of the short edge of the pillowcase is reserved, the pillow core also needs to be stuffed into the pillowcase for a very deep distance when filling the core; 3. the zipper is arranged on the pillowcase, so that the operation is complicated, and the zipper is easy to damage.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provides the pillowcase convenient for filling the pillow core, the pillowcase fabric has the characteristics of high elasticity, difficulty in losing elasticity and high recovery rate, the pillow core is more easily placed into the pillowcase through the open opening arranged in the middle of the lower pillow sheet, and meanwhile, the pillowcase can be prevented from being torn from the opening by too much force, the pillow core is conveniently replaced, and time and labor are saved.

The purpose of the invention is realized as follows:

a high-elasticity pillow case comprises an upper pillow sheet and a lower pillow sheet, wherein the lower pillow sheet is made of knitted fabric with elasticity of 5% -200%, namely the knitted fabric can be increased to 105% -300% when being stretched, and an open opening is formed in the middle of the lower pillow sheet.

Further, the knitted fabric is spandex knitted fabric.

Further, the area of the opening accounts for 30% -70% of the total area of the lower pillow sheet.

Further, the shape of the opening is circular, oval or square.

Further, a wrapping edge is sewn along the edge of the opening.

Further, the width of the edge cover is 0.5-3 cm.

Furthermore, the opening on the back side can be free from any sewing treatment.

Compared with the prior art, the invention has the following advantages:

1. the pillowcase is made of spandex knitted fabric, and spandex has the characteristics of high extensibility (500-700%), low elastic modulus (200% extension, 0.04-0.1 g/denier) and high elastic recovery rate (200% extension, 95-99%), so that the spandex knitted material can be very easily stretched; therefore, the pillow case made of the spandex knitted fabric is high in elastic force, not prone to elastic loss and high in recovery rate, the pillow core can be placed into the pillow case through the inlet formed in the lower pillow piece more easily, meanwhile, the pillow case can be prevented from being torn from the opening due to too much force, the pillow core is convenient to replace, time and labor are saved, and the spandex knitted pillow case is particularly suitable for being used in places such as hotels, hotels and beauty parlors where the pillow core needs to be replaced frequently.

2. The lower pillow piece is made of spandex knitted fabric, and the periphery of the opening is not required to be subjected to edge covering treatment, so that the lower pillow piece can be dug into a hole in the processing process, edge covering is not required, and the situations of line breakage and the like are avoided in the using process. Thus reducing the production cost of the pillow case.

3. The opening of the pillowcase is arranged on the lower pillow sheet, and the opening faces downwards to be in contact with the bed surface after the pillow core is filled, so that the normal use of the pillow is not influenced, and the pillow core is not easy to become dirty due to the opening.

4. The invention sews the edge of the lower pillow piece along the edge of the opening, which makes the pillow case more beautiful.
