高效短流程嵌入式纺纱的综合分析

为了分析高效短流程嵌入式纺纱的实际价值,对高效短流程嵌入式纺纱的原理、作用、优缺点、生产成本、棉纱质量、试验数据及其该纺纱方法对原料质量及其所依存的条件等等进行了深入的分析.通过新疆溢达公司采用该原理生产1.77 tex纱的实践试验,说明采用高效短流程嵌入式纺纱突破了目前纺纱号数的瓶颈,可以实现特细号纱1.46 tex、1.17 tex甚至0.97 tex棉纱的生产;而目前高效短流程嵌入式纺纱的纺纱过程、棉纱的作用、成本、织物的最终用途等都存在较为明显的问题,不会给产品质量的稳定及改进、提高和生产成本的降低带来有益作用;至于纺纱的生产效率和生产的织物水溶性纤维溶解后所得到织物的效果都是很差的.这样的纺纱和织物的生产无实际应用价值,只有通过未来在改进纺纱形式后织物的质量才会得到真正提高.     

用转杯纺微纤纱织衬衫布

衬衫织物是采用 6ｔｅｘ～ 3 0ｔｅｘ的纱线 ,根据最终要求织成的不同组织和结构的织物。高价值衬衫由 1 2ｔｅｘ较细的纱线制成 ,以上织物具有较高的经纬密度。这些纱线由环锭纺纱系统生产。尽管环锭纺纱线具有足够强度 ,但是它们的疵点水平仍然比自由端转杯纺纱线高。在转杯纺过程中生产出低水平的不太完善的纱线是可能的 ,但问题是转杯纺纱线常常是低强度 ,粗糙的手感和高的断头率 ,这在细纱转杯纺纱线的纺制过程中是要防止的。转杯纺要求纱线的横截面有 1 0 0根～ 1 2 0根纤维 ,这比环锭纺 5 0根纤维更令人满意。印度生产了单丝为 0 8…     

纱线合股数对3种组织织物保形性的影响

研究纱线合股数和织物组织对织物保形性能的影响。采用细度相同的9.6 tex单纱和4.8 tex×2、3.2 tex×3和2.4 tex×4股线,以相同经纬密分别制织成平纹、二上二下方平、二上二下左斜纹组织的织物。测试了各织物的折皱回复性,采用人工主观评价和客观评价方法评价了织物平整度。结果表明:随着纱线合股数的增加,织物的折皱回复性变差,平纹双股线织物折皱回复性最好,方平织物中单纱和双股线织物折皱回复性相近,斜纹单纱织物的折皱回复性好于其他织物;平纹和方平单纱织物的平整度等级高于股线织物,纱线合股数对斜纹织物的平整度无明显影响;织物组织结构交织点少、浮线长,结构越松散,其保形性越好。认为:纱线合股数和织物组织对织物保形性具有一定影响。

Influence and comparison of emerging techniques of yarn manufacturing on physical–mechanical properties of polyester-/cotton-blended yarns and their woven fabrics

Abstract

In this study, the physical–mechanical properties of ring spun, ring compact, rotor and air-vortex yarns were investigated. The study was carried with yarn having linear densities of 24.4 tex and 36.7 tex, which were then converted to woven fabrics. The ring spun yarns have higher values of strength but also with higher strength irregularities. Extra-ordinarily low hairiness was observed in air-vortex yarns due to its unique yarn formation technique. The deviation rate (DR) of yarns have correlation with the mass spectrogram of respective yarns obtained from USTER Tester 5. Rotor and air-vortex yarns exhibited higher coefficient of friction. The woven fabrics made from ring spun yarns exhibited higher tensile and tear strength with higher elongation at break. The fabrics made from air-vortex yarns have very good pilling grade due to less protruding fibres on their surface and good structural integrity.

为开发天然抗皱免烫衬衫面料,探讨纺纱方式对拉伸弹性及抗皱性的影响,用聚酯(PET)长丝与纯棉纱通过全聚纺、全聚纺包芯、全聚赛络纺包芯、全聚赛络纺双丝包芯、全聚纺包芯合股5种纺纱方式,开发了5种线密度为14.8 tex的纱线,并织造了相同规格的5种织物,对织物的抗皱性、尺寸稳定性、刚柔性、拉伸变形性等进行测试与分析。 结果表明:纤维的急弹性变形比例、初始模量越大,织物的弹性及折皱回复性越好;纱线的毛羽少、表面光洁、条干均匀、初始模量大,则织物抗皱性好;全聚赛络纺包芯纱、全聚纺包芯双合股纱的抗皱性、尺寸稳定性、拉伸弹性回复性均较好,织物的外观平整度均为3.5级;全聚赛络纺包芯纱比全聚纺包芯纱双合股纱生产流程短,成本低,更适合用于开发高保形免烫衬衫面料。

The effect of core-sheath proportion on the characteristics of fabrics produced with hollow yarns: part II comfort and mechanical properties

The study aims to investigate the effect of hollow yarn structure and the sheath-core proportion of hollow yarns on the permeability properties of the knitted fabrics. In order to accomplish this, core yarns in the yarn count of 59 tex were produced by using cotton, viscose, wool, and polyester fibers in the sheath and different ratios of polyvinyl alcohol (PVA) in the core. After completion of yarn production on ring spinning frame, the yarns in the form of packages were used to produce plain knitted fabrics. Fabrics were then divided into two groups, one of which was washed during a time period in order to remove PVA from the core to obtain hollow yarn structure. Air and water permeability, and wicking properties of the knitted fabrics were measured before and after washing processes. Mechanical properties such as pilling and bursting strength of the fabrics were also examined. The results show that washing process and PVA proportion used to produce core spun yarns have a significant effect on the permeability and mechanical properties of the fabrics.     

Investigation on moisture management properties of knitted fabrics produced from vortex-spun yarns

Abstract

The aim of this study was to investigate the liquid moisture management performance of knitted fabrics produced from vortex-spun yarns using different kinds of fibers and ratios. For this purpose, the vortex-spun yarns with 19.7 tex were obtained in different blend ratios in Murata Vortex Spinner by using different fibers. Then, these yarns were knitted in a circular knitting machine at two different stitch lengths and dyed considering fiber types. Moisture management properties of the produced fabrics were tested. The results revealed that moisture management properties of vortex knitted fabrics were much affected by fiber types in comparison with fabric tightness. Modal and nylon fibers have shown very positive results in terms of moisture management performance. The vortex-spun yarns having a low diameter, high shape values that are more rounded, and high density improved moisture management performance of the fabrics whereas the hairy yarns and higher fabric thickness reduced it.

The Influence of the Spinning Process,Yarn Linear Density,and Fibre Properties on the Hairiness of Ring-spun and Rotor- spun Cotton Yarns

Cotton–spun yarns from 34 staple stocks were manufactured by means of the ring–spinning process (34 yarns) and a rotor–spinning process (29 yarns) and tested for hairiness with the Shirley Hairiness Meter. For each spinning system, yarns were spun at two values of yarn linear density (15 and 30 tex for ring–spinning and 30 and 50 tex for rotor–spinning), but the twist multiplier was kept constant within the series for each spinning process.

The higher hairiness of ring–spun yarns and an increase ln hairiness with the yarn linear density were confirmed. The effect of the fibre parameters on yarn hairiness explains only about 30% of the total effect for ring–spun yarns and 40% for rotor–spun yarns. Fibre length and its uniformity are the fibre properties having the greatest influence on the hairiness of both ring– and rotor–spun yarns, the Micronaire index having only slight influence on the hairiness of ring–spun yarn.
