    • The present invention provides a glass fiber strand comprising at least one glass fiber at least partially coated with a sizing composition prepared from ingredients comprising; at least one starch; at least one lubricant; and at least one silane coupling agent comprising: [((R1)bY)aR23-aSiR3]2NX, wherein R1 and R2 are each monovalent radials; R3 is a divalent linking group; a is 1 to 3; X is (R4)bZC(═O)CH(Q)CH(Q)—, wherein Z is CH2, O, S or N, Q is H, alkyl, aryl, alkaryl, or C(═O)ZR4 and R4 is a hydrocarbon moiety of one to twenty carbon atoms, hydrogen, a silyl group or an organic polymer; Y is oxygen, nitrogen or sulfur; and b is 1 or 2 depending upon the valency of Y. In one particular embodiment of the invention, the silane in the aqueous sizing composition is (CH3)3COC(═O)CH2CH2N[CH2CH2CH2Si(OCH3)3]2.
    • 本发明提供一种玻璃纤维束,其包含至少一种至少部分涂覆有由以下成分制备的施胶组合物的玻璃纤维: 至少一种淀粉; 至少一种润滑剂; 和至少一种硅烷偶联剂,其包含:[((R1)bY)aR23-aSiR3] 2NX,其中R1和R2各自是单价径向; R3是二价连接基团; a是1到3; X是(R4)bZC(= O)CH(Q)CH(Q) - ,其中Z是CH2,O,S或N,Q是H,烷基,芳基,烷芳基或C(= O)ZR4和R4 是1至20个碳原子的烃部分,氢,甲硅烷基或有机聚合物; Y为氧,氮或硫; 并且b是1或2,这取决于Y的化合价。在本发明的一个具体实施方案中,水性施胶组合物中的硅烷是(CH 3)3 COC(= O)CH 2 CH 2 N [CH 2 CH 2 CH 2 Si(OCH 3)3] 2。
