本発明は、優れた接着性を有し、耐熱性及び風合の良好
な接着繊維製品を与えるホントメルト型バインダー繊維
に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a true-melt type binder fiber that has excellent adhesive properties and provides a bonded fiber product with good heat resistance and feel.

の詰物、キルテイング用中入れ綿等の繊維構造物におい
て構成繊維（主体繊維という）相互間を接着する目的で
、ホットメルト型バインダー繊維が広く使用されるよう
になってきた。(Prior art) In recent years, constituent fibers (mainly Hot-melt binder fibers have come to be widely used for the purpose of bonding together fibers (called fibers).
そして、主体繊維としては、比較的安価で、優れた物性
を有するポリエステル繊維が最も多く使用されており、
これを接着するバインダー繊維もポリエステル系のもの

それを用いて接着したポリエステル繊維構造物が提案さ
れている（例えば、米国特許第４，１２９，６７５号ば
か多数）。The main fiber used is polyester fiber, which is relatively inexpensive and has excellent physical properties.
It is preferable that the binder fibers used to bond these fibers are polyester-based.9 Various polyester-based binder fibers and polyester fiber structures bonded using the same have been proposed (for example, U.S. Pat. No. 4,129,675). ).
ところで、ポリエステル系バインダー繊維は。By the way, what about polyester binder fibers?
一般にコポリエステルを用いるので、明確な結晶融点を
示さない場合が多く５通常、９０〜２００℃で軟化する
。そして、その軟化点以上、主体繊維の融点未満の温度
で熱処理して主体繊維相互間を接着するものである。Since copolyesters are generally used, they often do not exhibit a clear crystalline melting point5 and usually soften at 90 to 200°C. Then, the main fibers are bonded together by heat treatment at a temperature higher than the softening point and lower than the melting point of the main fibers.
ところが、バインダー繊維のガラス転移点以上の高温雰
囲気で使用される産業資材用の繊維製品の場合、明確な
結晶融点を示さないバインダー繊維で接着すると、高温
雰囲気においては、接着強度が低下し、製品の強度低下
、嵩高保持性低下環が起こるという問題があった。However, in the case of textile products for industrial materials that are used in high-temperature environments above the glass transition point of the binder fibers, bonding with binder fibers that do not have a clear crystalline melting point will reduce the adhesive strength in the high-temperature atmosphere, causing the product to deteriorate. There was a problem in that the strength of the material decreased and the bulk retention decreased.
また、結晶融点を示さないコポリエステルと高融点ポリ

うという問題があった。In addition, when a composite fiber type binder fiber is made of a copolyester that does not exhibit a crystalline melting point and a high melting point polyester,
After spinning, the fibers fuse when hot drawn, so they must be cold drawn, and with cold drawn binder fibers, there is a problem in that the high melting point polyester shrinks due to heat during use, impairing the appearance of the bonded fiber product.

Publication No. 125424 discloses a true-melt adhesive made of polybutylene terephthalate/polybutylene isophthalate copolyester. There was a problem in that the material may be hard to the touch.
（発明が解決しようとする問題点）
本発明は、上記のようなバインダー繊維の問題点を解消
し、熱延伸法により製造することができ。(Problems to be Solved by the Invention) The present invention solves the above-mentioned problems of binder fibers and can be produced by a hot stretching method.

。A hot-melt binder fiber that can be effectively bonded without damaging the appearance of the fiber structure, and provides a soft-touch bonded fiber structure with little loss of adhesive strength even when used in high-temperature environments. This is what we are trying to provide.
（問題点を解決するための手段）
本発明は、上記の目的を達成するもので、その要旨は、

らなるホットメルト型バインダー繊維にある。(Means for solving the problems) The present invention achieves the above objects, and the gist thereof is as follows:
With terephthalic acid as the main acid component and a 2 molar ratio of 90/10~
A low melting point copolyester with a crystal melting point of 130 to 210 °C and a high melting point of 220 °C or higher with a crystal melting point of 60/40 1,4-butanediol and 2,2-dimethyl-1,3-propanediol as the main diol components. The hot-melt type binder fiber consists of a composite fiber in which the former occupies at least a portion of the fiber surface.

ール成分とする結晶融点１３０〜２１０℃のものである
。The low melting point copolyester in the present invention has a clear crystal melting point and a high crystallization rate, and has terephthalic acid as the main acid component and has a molar ratio of 90/10 to 60/40.
The main diol components are 1,4-butanediol (BD) and 2,2-dimethyl-1,3-propanediol (NPC) and have a crystal melting point of 130 to 210°C.
結晶融点が１３０℃未満ｔは、接着した繊維製品を高温
雰囲気で使用したときに接着強度が低下して好ましくな
く、２１０℃を超えると接着温度を主体繊維の融点に近
い高温にしなければならないため。If the crystal melting point is less than 130°C, the adhesive strength will decrease when the bonded textile product is used in a high-temperature atmosphere, which is undesirable. If it exceeds 210°C, the bonding temperature must be raised to a high temperature close to the melting point of the main fiber. .
主体繊維の物性や繊維構造物の形状を損ない好ましくな
い。This is undesirable because it impairs the physical properties of the main fiber and the shape of the fiber structure.

、ジエチレングリコール。Such a copolyester with a crystal melting point of 130 to 210°C is obtained by selecting a molar ratio of a terephthalic acid component and a diol component consisting of BD and NPC within the above molar ratio range so as to have a predetermined crystal melting point. It can be obtained by copolymerizing. (If the molar ratio of the diol component is out of the above range, it may not show a clear crystal melting point or the melting point may become high.) In addition, the low melting point copolyester may be mixed with other materials as long as its properties do not change significantly.

A copolyester containing 0 mol % or more is preferably used from the viewpoint of strength properties.

合紡糸する際の操業性が悪くなるので。Note that if the melt viscosity of the 8 low melting point copolyester is too low, the operability during composite spinning will be poor.

It is desirable to set the value to 200 poise or more in sec.

途に応じて適当な複合形態を選択するのがよい。A composite fiber or the like in which a high melting point polymer is spun by inserting a stationary mixing element into a seabird type or spinning puncture and dispersed in layers or stripes can be obtained. A concentric sheath-core type provides good spinning properties, while an eccentric type provides latent crimpability, so it is best to select an appropriate composite form depending on the application.

The stretching is preferably carried out by a hot stretching method, and is carried out by heating the supply roller or by providing a hot plate between the supply roller and the stretching roller.

性を示すものと認められる。(Function) Since the binder fiber of the present invention has crystalline copolyester as a thermal adhesive component, once the main fiber is melted and bonded, the copolyester quickly crystallizes when the temperature is lowered, and even if the temperature is raised again, It is recognized that the adhesive strength does not decrease up to a temperature near the melting point of the copolyester and exhibits excellent adhesiveness with excellent heat resistance.
