Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to pillows for bedding, which have good cushioning properties and excellent breathability and moisture permeability.Especially, comfortable sleep can be obtained even in a hot and humid environment like summer in Japan, and it is easy to use. It is made to be washable.

[0002]

[Prior art]

 Sleeping conditions have long been called head-and-foot fever.In order to satisfy this condition, pillow stuffing has been devised in various ways, using buckwheat, rice hulls, red beans, panya, feathers and urethane foam. Recently, resin chips of several millimeters in diameter and several millimeters in length made by cutting pipes made of synthetic resin such as polypropylene have come to be used.

[0003] However, these conventional pillow fillings generally have poor air permeability and are difficult to wash. And although it depends on the taste of the user, buckwheat, rice hulls, red beans, resin chips, etc. have poor cushioning properties, and panya, feathers, urethane foam, etc., on the other hand, are too soft and tend to build up heat. There were problems such as buckwheat, rice hulls, panya, feathers, etc., which tended to become filthy due to the propagation of various bacteria.

[0004]

[Problems to be solved by the invention]

 This device has a moderate elasticity between a hard stuffing made of buckwheat, rice hulls, red beans, resin chips, etc. and a soft stuffing made of panya, feathers, urethane foam, etc. The present invention provides a pillow that is more breathable and more permeable than conventional pillows, hardly allows bacteria to propagate, and is easy to wash.

[0005]

[Means for Solving the Problems]

 The pillow according to the present invention is a net-like cushion plate formed by accumulating filaments of a thermoplastic elastomer so that a large number of loops are randomly formed by the filaments and fusing the contact portions between the filaments. The core material is press-fitted into a bag-like wrapping made of a knitted fabric having a honeycomb-shaped open hole, and the insertion opening is closed.

[0006] In this invention, the mesh-like cushion plate is formed by extruding filaments equivalent to several thousand deniers made of a thermoplastic elastomer having thermoplasticity and rubber-like elasticity at a high temperature, and immediately thereafter, rapidly cooling to accumulate on a flat surface. At that time, a large number of loops are randomly formed with the above-mentioned filaments, and the contact portions between the filaments are fused to each other. It is similar to loofah in terms of its network. However, it is formed of thermoplastic elastomer filaments, which are thicker and have rubber-like elasticity than spunbond non-woven fabric or loofah constituent fibers, and these filaments form many loops. Since they are integrated to form a kind of spring, they have excellent elasticity and air permeability and low compression set compared to spun-bonded nonwoven fabrics and loofahs, and are difficult to drip.

[0007] Then, the above-mentioned net-like cushion plate having excellent elasticity and air permeability is used as a core material, and is pressed into a bag-like wrapping cloth made of a knitted fabric having a honeycomb-shaped open hole, which is rich in air permeability and elasticity. That is, the core material having high elasticity and air permeability is pressed into a bag-like wrapping material having high elasticity and air permeability, the wrapping is tensioned, and the insertion opening of the wrapping is closed by sewing or the like. Therefore, it can be used as a pillow as it is, or it can be used in a normal pillowcase. The cushioning properties are about the same as those of conventional pillows using hard stuffing and pillows using soft stuffing.They are hard to settle down, have good head stability, have good air permeability and moisture permeability, and can be used in summer. It is cool and feels good, does not protrude the end of the wire that constitutes the core, and can be washed as it is after use by removing the pillow cover, draining easily, and drying easily.

As the above-mentioned thermoplastic elastomer, any one can be used. In particular, polyester such as polyethylene terephthalate or polybutylene terephthalate is used as a hard segment, and aliphatic polyether such as polytetramethylene glycol is used as a soft segment. Polyester elastomers are preferred.

The apparent density of the net-like cushion plate made of the thermoplastic elastomer filaments is preferably 0.025 to 0.045 g / cm ³ . This apparent density is less than 0.025 g / cm ^3, soft too as a pillow, and insufficient bearing capacity of the human head, the head becomes unstable, too hard exceeds 0.045 g / cm ³ in the opposite, In addition, the repulsive force on the head becomes stronger, the head becomes unstable, and sleep is disturbed. The thickness of the mesh cushion plate is set according to the height of the pillow and how to use the mesh cushion plate. For example, since the preferred height of the pillow is 60 to 80 mm, the thickness is preferably 30 to 40 mm when the net-like cushion plates are used in two layers.

[0010] The above-mentioned net-like cushion plate can be used in any form. For example, a net-like cushion plate having a thickness of 60 to 80 mm is cut into a rectangle corresponding to the planar shape of a pillow, and one of the sheets is used as it is as a core material. The mesh cushion plate may be as thin as 10 to 20 mm, and the width is almost equal to the width of the pillow (the length in the direction crossing the head) and the length is the number of pillows. It may be formed in a double band-like shape and roll-wound, so that the total thickness becomes 60 to 80 mm. In addition, the thickness is set to 30 to 40 mm, the width is almost equal to the width of the pillow, and the length is formed into a rectangle of about twice the length of the pillow. It is also possible to fold toward each other and make the end faces abut each other to form a two-layer structure. In this case, simply fold one net-like cushion plate to form a two-layer structure, and form the round curved part formed by the bending. It can be directed to the front and back of the pillow, improving both productivity and appearance.

[0011] The wrapping covering the core material is formed of a honeycomb-shaped knitted fabric having an open hole on the entire surface. This honeycomb-shaped knitted fabric is knitted into a square mesh (mercuset) or a turtle-shaped tulle structure using a synthetic fiber yarn such as polyester or nylon, a cotton yarn or a composite yarn of a synthetic fiber and a cotton fiber as a knitting yarn. Are preferred. In particular, using a double Raschel machine, both the surface structure and the back structure are made to be the mesh structure such as the above-mentioned Mercusette and tulle, and the monofilament yarn of synthetic fiber is used as the binding yarn connecting the front structure and the back structure. The double raschel knitted fabric used is preferable because it has excellent breathability and stretchability in the vertical and horizontal directions and has elasticity in the thickness direction. The thickness of the honeycomb-shaped knitted fabric is preferably from 3 to 10 mm, and if it is less than 3 mm, the leading end of the wire constituting the core material tends to protrude from the open hole, and if it exceeds 10 mm, handling becomes difficult.

It is preferable to form a depression corresponding to the occipital region at the time of sleep at the center of the upper surface of the pillow. The stitches can be stitched along three to three straight lines, and the core material and the wrapper can be tightened with the sewing thread at the stitched portion to form depressions on the upper and lower surfaces of the central portion. The straight length of the suturing portion is preferably 150 to 250 mm. When two or three straight lines are provided at the seam portion, the interval (in the case of three lines, the interval between the two outer straight lines) is preferably 50 to 150 mm. The depth of the depression is preferably 10 to 30 mm at the position of the suture portion. If the depth is less than 10 mm, the head becomes unstable, and if it exceeds 30 mm, excessive force is applied to the muscles from the neck to the shoulder. , Causing discomfort.
