に優れた詰綿体およびその製造法に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a stuffed material having excellent mold surface resistance, set resistance, drapability, and bulkiness, and a method for producing the same.
従来、羽毛ふとんは最高級品として賞賛され、羽毛が有
する特性を満足するふとんを合成繊維綿から製造するこ
とはできなかった。Up to now, down comforters have been praised as the highest quality products, but it has not been possible to manufacture a comforter that satisfies the characteristics of down from synthetic fiber cotton.
このような高級素材を合成繊維綿と混用することも、い
たづらに品位を低下させるだ（プであるとの考えから試
みられたこともなかった。Mixing such high-quality materials with synthetic cotton has never been attempted, as it is thought to be extremely degrading.
しかも、羽毛は資源的に限界があり、最近の自然破壊の
情況から激減の様相を呈している。Moreover, feathers are a limited resource, and due to the recent destruction of nature, they appear to be decreasing rapidly.
上記のような最高級品の羽毛ふとんでも、中綿の羽毛が
ずれ易く、型面れが大きいという欠点を右しており、使
用後には修正する必要があった。Even the highest quality down futons, such as those mentioned above, suffer from the disadvantages that the feathers in the filling tend to shift easily and the shape is large, and it is necessary to correct them after use.
そこで、羽毛を通常の繊維綿と混用することで上記欠点
を改善しようと試みたが、羽毛は通常の繊維とは明確に
相違する形状を有するものであり、単に）捏合しても満
足な混合分散状態は得られず、また羽毛そのものを１シ
′Ｉ傷するという問題がめった。Therefore, attempts were 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 kneaded, they cannot be mixed satisfactorily. A dispersion state could not be obtained, and the problem of damaging the feather itself occurred frequently.
本発明は、かかる羽毛の問題点について検討した結果、
特定の方式を採用することにより、羽毛と繊維綿との混

可能ならしめたものでおる。As a result of studying the problems of such feathers, the present invention has been made based on the following:
By adopting a specific method, we have succeeded in mixing and dispersing feathers and fiber cotton, making it possible to effectively utilize valuable feather resources.
すなわち、本発明は空気吹込み技術を応用して、羽毛を
理想的な形で通常の繊維綿と混合して、詰物構造を形成
することに成功したものでおる。That is, the present invention has succeeded in forming a stuffed structure by applying the air blowing technique and mixing feathers with ordinary fiber cotton in an ideal form.

徴とする詰綿体の製造法である。(3) Introducing the opened short fibers and feathers into a fan, or by introducing the feathers and short fibers into a fan after opening or supplying the feathers to a card at the same time. The mixed cotton is mixed at 10 to 80% on the double side, and fed into a forming machine by the blowing force of the fan, so that the mixed cotton is laminated in layers in a direction substantially perpendicular to the flat plane of the side material. This is a method of manufacturing cotton.
本発明でいう羽毛とは、通常羽毛ふとんや羽毛中綿構造
体として適用される、フェザ−やダウン、またはこれら

、ざらに羽毛独特の風合などが得られにくくなる。Such feathers account for 10 to 80% by weight of the total cotton, preferably 2% by weight of the total cotton.
It is mixed in an amount of 0 to 70% by weight, more preferably 30 to 60% by weight. If the blending ratio is too high, the cotton will shift significantly and compressive recovery properties will be reduced; if the blending ratio is too low, it will be difficult to obtain the bulkiness, drapability, and texture unique to feathers.

~0.5C1/cm" is suitable.
詰綿体の綿溝造は、側地の偏平面に対してほぼ直交する
方向に別状に積層されている点にある。The cotton groove structure of the cotton wadding body consists in that it is laminated separately in a direction almost perpendicular to the flat plane of the side material.

線ずれ性、嵩高性のいずれをも満足するものである。At least 60% of the feathers in such a layer, preferably 9096 or more, are arranged substantially parallel to the plane of the layer, that is, in a direction perpendicular to the side plane. This vertically arranged structure of feathers exhibits excellent effects on cotton properties such as bulkiness and secondary line slippage resistance. The present invention
Due to this effect, the above-mentioned excellent performance can be imparted to the stuffed material. That is, it satisfies all of the feather texture, drapability, side line slippage property, and bulkiness.
次に本発明の詰綿体を製造する方法について説明する。Next, a method for manufacturing the cotton stuffing of the present invention will be explained.
本発明は、羽毛と繊維綿、つまり、羽毛と開繊された短

ものである。The present invention provides a method for introducing feathers and fiber cotton, that is, feathers and opened staple fibers into a fan, or feeding feathers and staple fibers simultaneously to a loom or card and then introducing them to the fan. By any method, 10 to 80% by weight of feathers are mixed and fed into the molding machine by the blowing force of the fan.
V. The cotton stuffing is produced by laminating the mixed cotton in layers in a direction substantially perpendicular to the flat plane of the side material.
ここで、短繊維は開繊されているものを羽毛と混合する
点がｍ要である。Here, it is essential that the short fibers be opened and mixed with the feathers.
かかる構成をとるには、予め開繊された短繊維を混合す
るか、短繊維のみが開繊されて羽毛はその作用を受けな
いような開繊機またはカードを同時に通すかの２つの方
法がおる。There are two ways to achieve such a configuration: mixing short fibers that have been opened in advance, or simultaneously passing through a spreader or card that opens only the short fibers and leaves the feathers unaffected. .
前者の方法では、予め開繊機またはカードに掛けた短繊
維を羽毛と混合してファンに導入すればよい。また後者

通すので、通常なら羽毛に損傷を与える。本発明では羽
毛同時供給の場合の開繊機またはカードのゲージを通常
よりも粗く設定したものを用いるものである。In the former method, short fibers that have been hung on a spreader or card in advance may be mixed with feathers and introduced into a fan. The latter method also passes the feathers and short fibers through an opener or card at the same time, which would normally damage the feathers. In the present invention, in the case of simultaneous feeding of feathers, a fiber opening machine or a card with a gauge set coarser than usual is used.
すなわち、通常のゲージでは１０／１０００〜３０／１
０００ （１ｎｃｈ）程度であるが、本発明に使用する
機械のゲージとしては、少なくとも４０／ １０００
（１ｎｃｈ＞以上、好ましくは５０／１０００ （１ｎ

000 (1 nch), but the gauge of the machine used in the present invention is at least 40/1000.
(1nch> or more, preferably 50/1000 (1n

It is set coarser than h.

へ送られ側地内に装填される。Next, the spread short fibers and feathers are introduced into a fan in a mixed state. The mixed cotton is sent to the forming hall by this cotton feeding fan and loaded into the side cloth.
かかる混合綿の装填方法については特公昭５６−２９５
５６号の方法に従って行うことができる。Regarding the method of loading such mixed cotton, Japanese Patent Publication No. 56-295
It can be carried out according to the method of No. 56.

ものである。The present invention is characterized by the fact that the air blowing technique is excellent in mixing feathers and short fiber cotton, and moreover, it is possible to mix 60% or more of the feathers, or even 90% of the feathers.
It has been discovered that the feathers have a loading effect of making more than 30% of the feathers stand upright, and the upright feathers make it possible to provide a cushion made of short fiber cotton, which has not been available in the past.

For this experiment, only the feathers were directly dyed black with j') (to make them easier to distinguish. In the horizontal striped chair shown in Figure 1, the loading method is layered (
It is clearly observed that it is in the form of annual rings. However, the direction of the feathers present in this layer was parallel to a plane (oblique plane) perpendicular to the thickness direction, but oriented in random directions within the perpendicular plane. Next, in the vertical cross section of FIG. 2, it was observed that the vertical surfaces were intermittently laminated in a layered manner.
