A double-bed circular knitting machine with a gauge of E17 and a needle bar diameter of 200 mm (8 in) was used to make three groups of plain weft knitted Tencel fabrics and three groups of modal knitted fabrics. The yarns were spun using three spinning methods: ring, rotor, and air-jet system. Their count was 20 tex. All the knitted fabric samples were manufactured under the same conditions. One-half of each knitted fabric sample remained unfinished, while the other half was finished. Structure parameters of all finished and unfinished knitted fabrics were analyzed, and the most significant parameters were compared. Tensile properties of the knitted fabrics in wale and course directions were measured. The difference in the elasticity of the knitted fabric was analyzed in particular, and the portions of knitted fabric stretch are given. The basic conclusion is that using equal yarn fineness, but different raw material composition and structure, the produced knitted fabrics had substantially different fabric masses per unit area. The raw material composition and construction of the yarn, that is, the yarn manufacturing process and the spinning process produce yarns of different structures and properties that are manifested in the structure and properties of the knitted fabric. Thus, the finishing process must be specific for each raw material composition and yarn structure.

比较采用不同纺纱方法纺制的天丝和莫代尔纱线制成的双面针织物

使用针距为E17、针杆直径为200毫米（8英寸）的双床圆针织机制作三组平纬针织Tencel面料和三组莫代尔针织面料。纱线使用三种纺纱方法纺制：环锭纺、转杯纺和喷气系统。他们的数量是 20 tex。所有针织物样品均在相同条件下制造。每个针织物样品的一半仍未完成，而另一半已完成。分析了所有成品和未成品针织物的结构参数，并比较了最显着的参数。测量针织物在纵行和横列方向上的拉伸性能。重点分析了针织物的弹性差异，给出了针织物的拉伸部位。基本结论是，使用相同的纱线细度，但原料成分和结构不同，生产的针织物的单位面积织物质量存在显着差异。纱线的原料组成和构造，即纱线的制造工艺和纺纱工艺，生产出不同结构和性能的纱线，这些纱线的结构和性能表现在针织物的结构和性能上。因此，后整理工艺必须针对每种原材料成分和纱线结构。纱线制造过程和纺纱过程生产出不同结构和性能的纱线，这些纱线表现在针织物的结构和性能上。因此，后整理工艺必须针对每种原材料成分和纱线结构。纱线制造过程和纺纱过程生产出不同结构和性能的纱线，这些纱线表现在针织物的结构和性能上。因此，后整理工艺必须针对每种原材料成分和纱线结构。
