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ットメルト型複合バインダー
繊維に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a hot-melt composite binder fiber that has excellent adhesive properties and provides a bonded fiber product with good heat resistance and feel.

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
が好ましく９種々のポリエステル系バインダー繊維及び
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１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 point (1) 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.

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
、嵩高保持性紙下等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 were problems such as a decrease in strength and bulk retention under paper.

場合、紡糸後、熱延伸すると融着するため、冷延伸しな
ければならず、冷延伸したバインダー繊維では、使用時
に高融点ポリエステルが熱収縮し、接着繊維製品の外観
を損なうという問題があった。In addition, when making composite fiber-type binder fibers or fibers from a copolyester that does not exhibit a crystalline melting point and a high-melting-point polyester, the cold-drawn binder fibers must be cold-drawn because they fuse when hot-drawn after spinning. In the case of fibers, there is a problem in that high melting point polyesters undergo heat shrinkage during use, impairing the appearance of bonded fiber products.

Publication No. 125424 discloses a hot-melt adhesive made of polybutylene terephthalate/polybutylene isophthalate copolyester. For example, when a nonwoven fabric is bonded using this adhesive, the bonded nonwoven fabric becomes paper-like. 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

ルト型バインダー繊維を提供しようとするものである。To provide a hot-melt binder fiber that can be effectively bonded without damaging the appearance of the fiber structure, and that provides a bonded fiber structure with a soft texture and less loss of adhesive strength even when used in a high-temperature atmosphere. That is.
（問題点を解決するための手段）

める複合繊維からなるホットメルト型複合バインダー繊
維にある。(Means for solving the problems) The present invention achieves the above objects, and its gist is as follows:
A low melting point copolyester with a crystal melting point of 90 to 210°C and a crystal melting point of 220°C or higher, which has a molar ratio of 90/10 to 40/60 as the main acid components and 1,4-butanediol as the main diol component. The hot-melt composite binder fiber consists of a high melting point polymer and the former occupies at least a portion of the fiber surface.
本発明における低融点コポリエステルは、明確な結晶融
点を有し、結晶化速度の大きいものであり、テレフタル
酸を主たる酸成分とし１モル比９０／１０〜４０／６０
のテレフタル酸（ＴＰ＾）とアジピン酸（ＡＡ）を主た
る酸成分とし、１，４−ブタンジオール（ＢＤ）を主た
るジオール成分とする結晶融点９０〜２１０℃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 1 molar ratio of 90/10 to 40/60.
The main acid components are terephthalic acid (TP^) and adipic acid (AA), and the main diol component is 1,4-butanediol (BD), and the crystal melting point is 90 to 210°C.
結晶融点が９０℃未満では、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 90°C, the adhesive strength will decrease when the bonded fiber product is used in a high-temperature atmosphere, which is undesirable. If it exceeds 210°C, the bonding temperature must be set 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.

剤を含有していてもよい。Such a copolyester with a crystal melting point of 90 to 210°C is prepared by mixing an acid component consisting of TPA and AA and a diol component consisting of BD within the above molar ratio range, and adjusting the molar ratio of the acid component so that a predetermined crystal melting point is achieved. It can be obtained by selecting and copolymerizing. (If the molar ratio of the acid component is out of the above range, the crystalline melting point will not be clear or the melting point will become high.) In addition, the low melting point copolyester
Other ingredients 9, such as polycarboxylic acids such as isophthalic acid, trimellitic acid, and sebacic acid, diethylene glycol, triethylene glycol, polyethylene glycol, polypropylene glycol, pentaerythritol, bisphenol A, and hydroquinone, may be added to the extent that their properties do not change significantly. It may also contain a polyol or the like as a copolymer component. It may also contain additives such as @flame agents, stabilizers, and colorants.

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.

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.
