Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a batting body excellent in shape collapse resistance, sag resistance, drape property, and bulkiness, and a method for producing the same.

[Conventional technology]

Conventionally, feather futon has been praised as the highest grade product, and it has not been possible to manufacture a futon that satisfies the characteristics of feathers from synthetic fiber cotton.

It has never been attempted to mix such a high-quality material with synthetic fiber cotton, or to think that it would merely deteriorate the quality.

Moreover, feathers are limited in resources, and have been in a state of sharp decrease due to the recent state of natural destruction.

[Problems to be solved by the invention]

Even the above-mentioned feather quilts of the highest grade have the drawbacks that the feathers of the batting easily shift and the shape of the batting is large, and it is necessary to correct them after use.

Therefore, an attempt was made to improve the above drawbacks by mixing feathers with ordinary fiber cotton, but feathers have a shape that is clearly different from ordinary fibers, and even if they are simply mixed, a satisfactory mixing dispersion is obtained. There was a problem that the condition could not be obtained and the feather itself was damaged.

The present invention, as a result of examining the problem of such feathers,
By adopting a specific method, we succeeded in mixing and dispersing feathers and fiber cotton, and enabled effective utilization of valuable feather resources.

That is, the present invention has succeeded in forming a padding structure by applying the air blowing technique to mix feathers with ordinary fiber cotton in an ideal form.

INDUSTRIAL APPLICABILITY The present invention is a stuffed body which is made of a mixed cotton of feather and fiber cotton, and is excellent in shape retention resistance, sag resistance, drape property, and bulkiness, and is also excellent in feeling and heat retention. It exhibits its characteristics.

[Means for Solving Problems] The present invention has the following configuration in order to achieve the above-mentioned object. That is, (1) A wadding body, characterized in that 10 to 80% by weight of feathers and short fibers are laminated in layers in a direction substantially orthogonal to the plane of the lateral ground.

(2) The cotton wool body according to claim (1), wherein at least 60% of the feathers are substantially parallel to the layer surface.

(3) Feathers are introduced either by introducing the opened short fibers and feathers into the fan, or by simultaneously feeding the feathers and short fibers to the opening machine or card and then introducing them into the fan. Mixing 10 to 80% by weight, and sending the mixed cotton into a molding machine by the blowing air force of the fan, and stacking the mixed cotton in layers in a direction substantially orthogonal to the flat surface of the lateral surface. It is a manufacturing method.

The term "feather" as used in the present invention refers to a feather, down, or a mixed type thereof, which is usually applied as a feather futon or a down filling structure.

Such feathers account for 10-80% by weight of the total cotton, preferably 20-70.
%, More preferably 30 to 60% by weight. If the mixing ratio is too high, the cotton slippage is large and the compression recovery property is deteriorated. If the mixing ratio is too small, it becomes difficult to obtain the bulkiness and drape property of the feathers and the unique texture of the feathers.

Examples of the synthetic fiber cotton that is mixed with the feathers in the present invention include staples such as polyester, polyamide, and acrylonitrile, which can be used alone or in combination. Of course, a preferred embodiment of the present invention is such a fiber cotton that has been smoothed with a silicone resin or a fluorine resin.

The fineness of the synthetic fiber cotton is 0.5 to 50 D, preferably 15 D or less, and the fiber length is 20 to 120 mm, preferably 30 mm or more. That is, the thinner and longer the better the entanglement property is and the more effective use can be made without impairing the properties of the feathers.

As a stuffed body of mixed cotton of such fiber cotton and feathers, in order to obtain performance superior to conventional products by utilizing the properties of feathers, 0.05 to 0.
5g / cm ² is suitable.

The cotton structure of the padding body is that it is laminated in layers in a direction substantially orthogonal to the lateral plane. This is a characteristic of the method of forming a cotton pad by the force of the wind, and usually has an annual ring shape. Depending on the case, the layer may be formed in the shape of an arc. In any case, layers are formed around the blast inlet in the form of annual rings or arcs.

The feathers in such a layer are arranged such that at least 60%, preferably 90% or more of the feathers are substantially parallel to the plane of the layer, ie in the direction perpendicular to the lateral plane. The vertical arrangement structure of the feathers exerts an excellent effect on cotton performance such as bulkiness and cotton shift resistance. According to the present invention, the above-mentioned excellent performance can be imparted to the cotton body due to such effects. That is, it satisfies all of the feeling of feather, drape property, cotton slip resistance, and bulkiness.

Next, a method for producing the stuffed body of the present invention will be described.

The present invention, the feather and fiber cotton, that is, the feather and the opened short fibers are introduced into the fan, or the feather and the short fibers are simultaneously introduced into the fan after being supplied to the opening machine or the card, By any one of the methods, the feathers are mixed in an amount of 10 to 80% by weight, and the mixed cotton is fed into the molding machine by the blowing air force of the fan, and the mixed cotton is laminated in a layer in a direction substantially orthogonal to the lateral plane of the lateral plane. , Manufactures a cotton body.

Here, it is important that short fibers are mixed with feathers that have been opened.

In order to take such a configuration, there are two methods of mixing short-fibers that have been opened in advance, or passing a fiber-opening machine or card at the same time so that only the short fibers are opened and the feathers are not affected by it. is there.

In the former method, the short fibers preliminarily applied to the opening machine or the card may be mixed with the feathers and introduced into the fan. In the latter method, the feathers and the short fibers are simultaneously passed through the opening machine or the card, so that the feathers are usually damaged. In the present invention, a fiber-opening machine or a card with a gauge set coarser than usual is used when feathers are simultaneously supplied.

That is, it is 10/1000 to 30/1000 (inch) with normal gauge
The gauge of the machine used in the present invention is at least 40/1000 (inch) or more, preferably 50/10.
It is set to 00 (inch) or more.

Specifically, the spacing in the coarse opening machine that opens between the feed roller and the cylinder, the roller card that opens between the worker roller and the cylinder, and the flat card that opens between the flat and cylinder is 0.04 inch or more. It is a rough setting.

Next, the opened fiber and the feather are mixed and introduced into the fan. The mixed cotton is sent to the molding machine by the cotton feeding fan and loaded into the side ground.

The mixed cotton can be loaded according to the method described in Japanese Patent Publication No. 56-29556.

The present invention has found that such an air blowing technique is excellent in mixing feathers and short-fiber cotton, and exhibits a loading effect of erecting 60% or more, and further 90% or more of the feathers, Due to the upright feathers, it is possible to provide a cushion made of short fiber cotton, which has never been obtained before.

Thus, the present invention can provide an ephemeral stuffed cotton body which is composed of short fiber cotton and yet has a good feather quality.

The present invention will be further described with reference to the following examples. (Example) Example 1 Feather 50% and polyester staple (10d, 38m)
m) 50% was mixed and this was applied to a 50/1000 (inch) coarse gauge opener. The obtained polyester staple was completely opened, but the feathers were not subjected to the opening operation.

This mixed cotton was introduced into a total cotton fan, and 450 g of mixed cotton was loaded into the side ground set in the molding machine by the blowing air, and 50 cm x
A 70 cm thick 15 cm thick cushion was produced.

For comparison, a cushion was prepared by loading 450 g of 100% feather with the same size and thickness using the same machine.

The cotton shift rate of Example 1 was determined by the following measuring method and was 5.2%.
Met. On the other hand, the comparative example showed a high cotton shift rate of 28%.

Furthermore, the loading state of the wadding body of Example 1 is obtained by slicing in a horizontal plane (FIG. 1) and a longitudinal sectional view (FIG. 2) cut in the thickness direction and in the longitudinal direction from the cotton blowing port,
Each was observed. For this experiment, only the feathers were dyed black with a direct dye to make it easy to distinguish. In the horizontal plane slice of FIG. 1, it is clearly observed that the loading method is layered (annular ring). However, the direction of the feathers present in this layer was parallel to the vertical plane (planar plane) in the thickness direction, but it was oriented randomly in the vertical plane. Next, in the longitudinal section of FIG. 2, it was observed that the vertical planes were intermittently laminated in layers.

(Measurement method of cotton misalignment rate) 450 g of cotton is packed into a side cloth of size 50 cm x 70 cm to form a cotton body with a thickness of 15 cm.

This stuffed body is divided into two equal parts, and a load of 20 cm in diameter and 10 kg in weight is repeatedly dropped 150 times from a height of 18 cm in the center of one half of it, and the change in thickness of the opposite center is measured. did. The cotton shift rate was calculated by the following formula.

Cotton deviation rate (%) = [(ι′−ι) / ι] × 100 ι: Initial thickness of stuffed body ι ′: Thickness of stuffed body after load drop test (effect of the invention) Is a stuffed cotton body that is made up of fiber cotton and can fully utilize the properties of feathers, and has excellent bulkiness, compression recovery, and no loss of shape due to cotton slippage such as feathers. It is possible to provide a stuffed cotton body having drape resistance, sag resistance, and a feather texture stably in a rational and efficient manner.
