る。Polyester fibers are treated with the adhesive solution thus prepared. This process is usually carried out by immersing the polyester fibers in an adhesive solution, squeezing the fibers with the adhesive on them using a pressure-adjusted squeezing roller, or passing them through a duever device with an adjusted fJIi pressure to remove excess adhesive. This is done by removing the adhesive (dip) and adjusting the amount of adhesive (dip) deposited to usually 1 to 10% by weight, preferably 4 to 7% by weight.
接着液を付与されたポリエステル繊維は9次いで1通常
、100〜160℃で、0.5〜10分間乾燥された後
、210〜250℃で10.5〜5分間熱処理される。The polyester fibers to which the adhesive has been applied are then dried, usually at 100 to 160°C for 0.5 to 10 minutes, and then heat treated at 210 to 250°C for 10.5 to 5 minutes.
この熱処理の温度が210℃未満では、繊維上への接着
剤皮膜の形成及びゴムとの反応が不十分で、満足な接着
力が得られず、一方、250℃を超える高温では、繊維
上に形成された接着剤皮膜が劣化して。If the temperature of this heat treatment is less than 210°C, the formation of an adhesive film on the fibers and the reaction with the rubber will be insufficient, making it impossible to obtain a satisfactory adhesive force. The formed adhesive film deteriorates.
接着力が低下したり、繊維を形成するポリエステルが熱
分解を起こすため、繊維の強力等が低下したりして、好
ましくない。This is undesirable because the adhesive force decreases, and the polyester forming the fibers undergoes thermal decomposition, resulting in a decrease in the strength of the fibers.

られる。(Function) In the present invention, since the adhesive liquid contains a high viscosity, that is, a high molecular weight condensed phenol compound, a strong adhesive film is easily formed on the fibers, and the heat treatment temperature after applying the adhesive is comparatively low. It is recognized that it exhibits high adhesive strength even at low adhesive strength.
