摘要： A process for producing a porous, film-like or fibrous structure of an aromatic polyester, which comprises
(1) forming a substantially non-oriented film-like or fibrous structure by melt-molding an aromatic polyester blend composed of
(A) an aromatic polyester containing an aromatic dicarboxylic acid as a main acid component and an aliphatic diol and/or an alicyclic diol as a main glycol component, and (B) at least one low-molecular-weight compound selected from the group consisting of imide compounds and isocyanurate compounds being compatible, but substantially non-reactive, with the aromatic polyester and having a molecular weight of not more than 1,000, the low-molecular-weight compound being present in an amount of 10 to 300 parts by weight per 100 parts by weight of the aromatic polyester, and (2) extracting at least a major part of the low-molecular-weight compound from the resulting substantially non-oriented film-like or fibrous structure with an organic solvent which can dissolve the low-molecular-weight compound but under the extracting conditions does not substantially dissolve the aromatic polyester.

摘要： A process for the preparation of a polyethylene terephthalate monofilament is provided in which a non-drawn monofilament formed from 100 ppw of polyethylene terephthalate and 5-150 ppw of a modified polyethylene terephthalate is subjected to two drawings, the first at 85-100°C in humid conditions, increasing the size by 2.8 to 4.0 times, the second at 180-250°C in a gas atmosphere, increasing the size by 1.5-2.5 times, and then to heat treatment at 180-250°C and a take-up ratio of 0.9-1.0. The monofilament prepared has been found to have a substantially identical or higher knot strength against tension and transparency, and an increased knot strength against impact than previously used polyethylene terephthalate monofilaments, and the monofilament also has been found to be superior to conventional nylon monofilaments without loss of linear strength and transparency. Such monofilaments find use as fishing line and racket gut.
摘要翻译：提供了一种制备聚对苯二甲酸乙二醇酯单丝的方法，其中将由100ppw的聚对苯二甲酸乙二醇酯形成的未拉伸的单丝和5-150ppw的改性聚对苯二甲酸乙二醇酯进行两个图，第一个在85-100℃ 在潮湿条件下，大小增加2.8〜4.0倍，第二次在180-250℃的气氛中，将其大小增加1.5-2.5倍，然后在180-250℃进行热处理，上升比例为0.9-1.0。已经发现所制备的单丝具有与先前使用的聚对苯二甲酸乙二醇酯单丝相比具有基本相同或更高的抗张力和透明度的结强度以及相对于冲击的结强度，并且单丝也被发现优于常规尼龙单丝而没有损失的线性强度和透明度。这种单丝可以用作钓鱼线和球拍肠。

摘要： A process of melt spinning a fibre-forming polymer having a high viscosity, more particularly polyethylene terephthalate having an intrinsic viscosity greater than 0.70 or nylon 66 having a relative viscosity greater than 45 and more preferably greater than 55, in which before melt spinning, there is added to the fibre-forming polymer between 0.1% and 10% by weight of another polymer which is immiscible in a melt of the fibre-forming polymer and which has an average particle size less than 3 microns in the melt immediately prior to spinning.
