    • Enhanced performance yarns (41, 81) which comprise, and are functional and economic alternatives to, 100% petroleum oil based virgin continuous filament yarns, and yarns of natural fibers and methods of making them. The yarns may comprise an inner portion of spun staple fibers of recycled plastic and an outer portion comprising a different material and incorporate highly significant amounts of recycled plastics, particularly post consumer recycled (PCR), thermoplastic material such as polyethylene terephthalate (PET) which contains medium to high levels of contamination. One embodiment of yarn comprises a core (17), an inner portion (5) of spun staple fibers surrounding the core, and an outer portion (41) comprising an inner helix (43) and an outer helix (45) formed of a material different from the inner helix.
    • 增强性能纱线(41,81),其包括100%石油基原始连续长丝纱线,以及天然纤维纱线及其制造方法,并且是功能性和经济性的替代品。 纱线可以包括再循环塑料的旋转短纤维的内部部分和包含不同材料的外部部分,并且包含高度显着量的再循环塑料,特别是消费后回收(PCR),热塑性材料如聚对苯二甲酸乙二醇酯(PET),其包含 中等到高水平的污染。 纱线的一个实施例包括芯部(17),围绕芯部的旋转短纤维的内部部分(5)和包括内螺旋(43)的外部部分(41)和由材料形成的外螺旋(45) 不同于内螺旋。

    • A polyester composite thick-and-thin multififament yarn having a natural fiber grandrelle yarn-like appearance and spun yarn-like appearance and hand is constituted from a polyester thick-and-thin multifilament yarn (A) having thick and thin portions alternately arranged with each other and a polyester multifilament yarn (B) having a high dyeability and a uniform thickness and, in each composite thick portion (a) of the composite yarn, the individual filaments of the yarn (B) forms a core part and the thick portions of the individual filaments of the yarn (A) are distributed around the core part to form a sheath part; and, in each composite thin portion (b) of the composite yarn, the individual filaments of the yarn (B) and the thin portions of the individual filaments of the yarn (A) are distributed in random mixture with each other; and, when the composite yarn is dyed, the composite thick portions (a) are colored in a lighter color and the composite thin portions (b) are colored in a darker color.
    • 具有天然纤维外链纱状外观和短纤纱状外观的手感的聚酯复合厚薄多纤维纱线由具有交替布置的厚而薄的聚酯粗细复丝纱线(A)构成, 彼此具有高染色性和均匀厚度的聚酯复丝纱线(B),并且在复合纱线的每个复合厚度部分(a)中,纱线(B)的单根细丝形成芯部分,并且厚部分 的纱线(A)的单丝分布在芯部周围,形成鞘部; 并且在复合纱线的各复合薄膜部分(b)中,纱线(B)的单根细丝和纱线(A)的单丝的薄部分彼此无规混合地分布; 并且当复合纱线被染色时,复合厚壁部分(a)以更浅的颜色着色,并且复合薄片部分(b)被着色成较暗的颜色。
