摘要：

混纺精梳纱线中各种纤维混纺比的准确性影响纱线的品质、风格及纺纱成本。为提高多纤维混合精梳纱中各种纤维混纺比的准确性,根据精梳过程中纤维层喂入量、梳理过程中的落纤量及纤维网输出量的平衡关系,建立精梳机喂入纤维卷投料比的数学模型,可根据纤维设计混纺比及精梳过程中的落纤率计算纤维的投料比。为验证纤维卷中各种纤维投料比计算方法的正确性,设计涤纶/棉/粘胶混纺比为40∶30∶30,实测3种纤维单独精梳的落纤率,计算得到3种纤维的投料比,纺制3种纤维混合的精梳纱。提出“纱线截面纤维根数统计法”测定实际混纺比,利用显微镜对纱线截面内涤纶、棉、粘胶3种纤维的种类进行辨别,并统计、计算了3种纤维的实际混纺比。结果表明:混纺精梳纱线中涤纶、棉、粘胶3种纤维的实际混纺比与设计混纺比的差异率均小于5%,符合GB/T 29862—2013《纺织品纤维含量的标识》规定的控制范围;纱线截面纤维根数统计法检测实际混纺比的效率较传统物理检测方法提高46.7%。

Abstract:

Objective In order to improve the accuracy of the blending ratio of various fibers in multi-fiber combed yarns, a mathematical model of the feeding ratio of fiber rolls in combing machines was established and validated experimentally. The "yarn cross-section fiber counting method" is proposed to determine the actual ratio of various fibers in blended yarns for improving the detection efficiency. This study provides an accurate and effective method for the determination of various fiber blending ratios in fiber rolls and the detection of various fiber blending ratios in blended yarns during multi-fiber blending and combing.

Method Tests were conducted for each type of single-component fiber rolls to determine the amount of fiber loss during combing. Based on the balance relationship among the fiber layer feed-in amount, fiber loss amount, and fiber web output amount during the combing process, a mathematical model was established for determining the feed ratio of combed fiber rolls. Using polyester, cotton, and viscose fibers at a designed blend ratio of 40∶30∶30, the fibers were blended and then combed before being spun into yarn. This study designed the spinning process flow, fiber blending methods, multi-fiber combing techniques, as well as the corresponding process parameters. Multi-fiber combed yarns were spun, and cross-sectional slices of the yarn were prepared. The actual blend ratio of the blended yarn was determined using the yarn cross-section fiber counting method.

Results The multifiber combed fiber roll casting ratio model was applied to determine the actual blending ratio using the statistical method of the number of fiber in the yarn cross-section. The actual measurement results showed that the contents of polyester, cotton, and viscose in the blended yarn were 39.21%, 31.48%, and 29.31%, respectively. The difference rates from the designed blend ratio were 1.98%, 4.93%, and 2.30%, respectively, which fell within the control range specified by national standards. The conventional physical method took 220 min to detect the actual blend ratio. By adopting the manual cross-section fiber counting method, the total testing time was approximately 150 min, a 46.7% increase in efficiency compared to the conventional physical testing method.

Conclusion Multi-fiber combed fiber roll feeding ratio of the mathematical model was proved to be useful in production practice and the ″yarn cross-section fiber counting method″ was shown operatable in determining the actual blend ratio of various fibers for multi-fiber blended yarns with convenience, fast speed and accuracy.
