Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to covers for general blankets, skin comforters, electric blankets, etc.

Structure of conventional examples and their problems In conventional duvet covers, blanket covers, etc.
The peripheral edges of two simply pieces of fabric with the same size on the top and bottom are sewn together to form a bag, except for the entrance. In this case, the two pieces of fabric are often made of different materials and structures, and both have different shrinkage rates, so due to shrinkage during washing, the one with less shrinkage will be stretched and rolled up, causing the shape to curl up. becomes deformed and becomes extremely difficult to use. Furthermore, since there was only an opening on one side, it was difficult to set the main body inside, especially at the corners.

Purpose of the invention This invention solves the above-mentioned conventional problems.
The purpose is to reduce dimensional changes after washing and reduce shape deformation, making it extremely easy to use, and also making it easier to interiorize the main body.

Structure of the invention In order to achieve the above object, the invention uses two pieces of fabric, in which the fabric with a higher washing shrinkage rate is larger than the fabric with a smaller washing shrinkage rate by the difference in shrinkage,
Further, a cut portion is provided at a corner portion of the fabric having a large washing shrinkage rate, and an opening is formed while slackening the fabric by the difference in shrinkage.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

In Figures 1 and 2, a fabric 1 made of nylon mesh fabric with a high washing shrinkage rate and a fabric 2 made of raised acrylic fabric with a small washing shrinkage rate are joined together along the entire periphery except for the loading/unloading opening 3. The fabric 1 is provided with triangular cut portions at the corners, and the cut portions are slackened by the difference in shrinkage and form openings.

Figure 3 shows the cutting dimensions of fabric 2 with a small washing shrinkage rate, and Figure 4 shows the cutting dimensions of fabric 1 with a large washing shrinkage rate, c ₁ > shrinkage difference/2, a ₁ < a ₂ , b ₁ ≧ b ₃ , a ₁ ≧
a ₃ .

Figure 5 shows how to match the corner parts of fabrics 1 and 2, and a ₁ a ₃ , b ₁ b 3 of fabrics 1 and ₂ so that c ₁ > c ₂ .
The parts are sewn together.

FIG. 6 shows the electric blanket main body 5 made of acrylic being set, and the main body 5 and the fabric 2 are fastened at the corners with polypropylene clips 6. If the above structure is sewn as shown in FIG. 5, the fabric 1 is larger by the difference in shrinkage, so it will not be deformed due to shrinkage after washing and will be easy to use.

Further, according to this embodiment, the corner portion has an opening 4.
, so when setting the main body 5, it is very convenient and easy to pull the corner of the main body 5 through the opening 4.

Effect of invention According to the present invention, the following effects can be obtained.

(1) It can prevent deformation due to dimensional changes after washing, making it easier to use, and since the opening absorbs slack, there is no need to absorb slack at the joint. Therefore, joining becomes easier and productivity is improved.

(2) Since the corners of blankets, etc. can be pulled through the opening, this interior decoration is very easy and convenient.

Claims (1)

[Scope of utility model registration request] A mesh fabric with a large washing shrinkage rate and a raised fabric with a small washing shrinkage rate are included, the mesh fabric has a size larger at least by the difference in shrinkage from the raised fabric, and the corner part of the mesh fabric is cut. This cover is formed by joining the same edge parts of the mesh fabric and the raised fabric other than the insertion/removal area for a futon or the like, and allowing the difference in shrinkage of the mesh fabric to slacken at the opening of the corner part consisting of the cut part and the raised fabric.
