摘要： A quasi monofilament having a high strength polyethylene fiber core with an adherent, abrasion resistant polymer sheath is prepared by feeding the core yarn through a crosshead die, while simultaneously supplying a polymer melt at a temperature greater than the melting point of the core yarn to the die, for sheathing the core yarn within the die with the melt under a sufficient pressure to cause the melt to adhere to the core yam. The abrasion resistant polymer sheath includes an effective amount of a first polymer having ethylene crystallinity, a density of at least about 0.94 g/cm.sup.3, and a melt index of less than about 0.1 g/10 min. The composition used to sheathe the core yarn is characterized by a weight average tensile strength at yield of greater than about 13.8 MPa. The quasi monofilament has utility in applications subjected to high abrasion, such as sports fishing lines, kite lines, dental floss, "weedeater" lines and tennis racket strings.
摘要翻译：通过将芯纱线通过十字头模头进给，同时在大于芯纱线的熔点的温度下向聚合物熔体提供聚合物熔体，制备具有粘附耐磨聚合物护套的高强度聚乙烯纤维芯的准单丝模具，用于在足够的压力下用熔体将模具内的芯纱线包覆以使熔体粘附到芯纱线上。耐磨聚合物护套包括有效量的具有乙烯结晶度的第一聚合物，至少约0.94g / cm 3的密度和小于约0.1g / 10min的熔体指数。用于包芯纱的组合物的特征在于产率大于约13.8MPa的重均拉伸强度。准单丝可用于运动钓鱼线，风筝线，牙线，“除草机”线和网球拍线等高磨损应用。

摘要： Solutions of ultrahigh molecular weight polymers such as polyethylene in a relatively non-volatile solvent are extruded through an aperture at constant concentration through the aperture and cooled to form a first gel of indefinite length. The first gels are extracted with a volatile solvent to form a second gel and the second gel is dried to form a low porosity xerogel. The first gel, second gel or xerogel, or a combination, are stretched. Among the products obtainable are polyethylene fibers of greater than 30 or even 40 g/denier tenacity and of modulus greater than 1000 or even 1600 or 2000 g/denier.
