Abstract

(57) [Summary] [Structure] A bedding, a comforter and a pillow using a core or core made of polyethylene, polypropylene or a copolymer thereof. [Effect] The comfort of mattresses, comforters and pillows was improved.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to bedding such as comforters, mattresses, and pillows.

[0002]

[Prior art and its problems]

 Bedding, such as mattresses, comforters, and pillows, is gradually compressed due to the pressure of the user's weight, and becomes thinner and less comfortable to sleep. In the present specification, such a phenomenon that the bedding becomes less bulky is referred to as "sag."

[0003] In order to reduce the "sagging" of the duvet and pillow, for example, a quilt and a bedding include a core, and the quilt is manufactured by winding cotton around the core. Polyester has conventionally been used as the core. In the case of pillows, conventionally, polyester short fibers were blown into a pillow case to manufacture them, but even in the case of such pillows, the use of the pillow caused a hetal phenomenon.

In the case of comforters and mattresses, the use of polyester cores reduces the settling of bedding and other bedding to some extent, but there has been a strong demand for further reduction of settling. In the case of pillows, buckwheat noodles and other pillows are often used, and the reputation for synthetic fiber pillows was not well received.

[0005]

[Problems to be solved by the device]

 It is an object of the present invention to provide a bedding that further reduces fatigue.

[0006]

[Means for Solving the Problems]

 As a result of various studies to solve the above-mentioned problems, the present inventor has produced a bedding, a mattress, and a pillow core by using polyethylene, polypropylene, or a copolymer thereof to produce the bedding. It was found that the fatigue of

That is, the present invention provides a mattress having a core produced by using at least one selected from the group consisting of polyethylene, polypropylene and a polyethylene-polypropylene copolymer.

The present invention also provides a comforter having a core produced by using at least one selected from the group consisting of polyethylene, polypropylene, and a polyethylene-propylene copolymer.

Furthermore, the present invention provides a pillow having a core material produced by using at least one selected from the group consisting of polyethylene, polypropylene and a polyethylene-polypropylene copolymer.

The core of the present invention used for a mattress or a comforter, and the core material of the present invention used for a pillow are at least one selected from the group consisting of the above-mentioned polyethylene, polypropylene and polyethylene-propylene copolymer. The core and the core material can be manufactured by mixing with other polymers within a range that does not change the characteristic of reducing fatigue.

The quilt of the present invention has a core having a thickness of 5 to 60 mm, preferably 5 to 40 mm, and more preferably 5 to 15 mm.

The thickness of the core of the mattress of the present invention is 20 to 60 mm, preferably 20 to 50 mm, more preferably 20 to 40 mm.

The thickness of the core material of the pillow of the present invention is about 15 to 25 cm. The core material may have a thickness of 15 to 25 cm, for example, by laminating a required number of cores of 20 to 30 mm and laminating them, or a core material having a thickness of 15 to 25 cm may be manufactured and used from the beginning.

The core and the core material of the present invention can be manufactured by using a known method such as batch foaming or cross-linking foaming.

The comforter and mattress of the present invention can be manufactured in the same manner as in the past by using a polyethylene core instead of the conventional polyester core.

The pillow of the present invention may be manufactured by, for example, accommodating a plurality of core materials having the above-mentioned thickness integrally formed by sticking a plurality of pieces or by foaming a batch in a container such as a pillow case. Alternatively, the batting made of short fibers of synthetic fibers or natural fibers currently used around the core material, or the batting further containing buckwheat may be wound and produced.

The core material used in the pillow of the present invention is preferably used by forming a plurality of slits to improve air permeability.

[0018]

[Effect of device]

 The mattress, comforter and pillow of the present invention using the polyethylene core has less fatigue than the conventional product, and the new soft feel can be maintained for a long time. Moreover, since polyolefins are lighter than conventional polyesters, they are easy to store.

[0019]

【Example】

 Hereinafter, the present invention will be described in more detail with reference to examples, but the present invention is not limited to these examples.

Example 1 and Comparative Example 1 A conventional mattress (comparative example 1) was manufactured by winding a cotton woven with a 1: 1 mixture of wool and polyester on a polyester core having a thickness of 30 mm. Also, a mattress of the present invention (Example 1) was manufactured in the same manner by using a polyethylene core (thickness: 30 mm) instead of the polyester core.

Both of these mattresses were used by 5 panelists for 6 months and evaluated for various items.

The average results for 5 panelists are shown in Table 1 below.

In the following Tables 1 to 3, ⊚ indicates that it is very good.

◯ indicates that it is good.

Δ indicates that it is normal.

The bulkiness indicates the softness of the futon.

Example 2 and Comparative Example 2 A conventional comforter (Comparative Example 2) was manufactured by winding a cotton woven with a 1: 1 mixture of wool and polyester on a polyester core having a thickness of 30 mm. Further, a quilt of the present invention (Example 2) was manufactured in the same manner by using a polyethylene core (thickness: 30 mm) instead of the polyester core.

Both of these mattresses were used by 5 panelists for 6 months and evaluated for various items.

The results are shown in Table 2 below.

A plurality of slits were formed in the core material, and the slits were placed in a pillow case to obtain a pillow of the present invention (Example 3). Further, a short pillow was blown into the pillow case to manufacture a conventional pillow (Comparative Example 3).

Both of these mattresses were used by 5 panelists for 6 months and evaluated for various items.

The results are shown in Table 3 below.
