Embodiment 1

[0045] A method for preparing blended yarn with evenly distributed component content, comprising the following steps:

[0046] (1) Determine the types of fibers in the blended yarn respectively polyester fiber and cotton fiber, wherein the mass percentage of polyester fiber is X 涤纶纤维 35%, cotton fiber mass percentage X 棉纤维 65%;

[0047] (2) Cotton fiber is a natural short fiber. It is difficult to control the uniformity of pure spinning single yarn and the number of fibers in the cross section. Therefore, cotton fiber is selected as the reference fiber. The average bulk density of cotton fiber ρ 棉纤维 1.54g / cm 3 , the average cross-sectional area S of cotton fibers 棉纤维 π×(10μm) 2 ; Average bulk density ρ of polyester fiber 涤纶纤维 1.38g / cm 3 , the average cross-sectional area S of polyester fibers 涤纶纤维 π×(8μm) 2 , according to the formula N 涤纶纤维 / N 棉纤维 =(X 涤纶纤维 ×S 棉纤维 ×ρ 棉纤维 / (X 棉纤维 ×S 涤纶纤维 ×ρ 涤纶纤维 ), to obtain the root number ratio N of polyester fiber / cotton fiber...

Embodiment 2

[0054] A method for preparing blended yarn with evenly distributed component content, comprising the following steps:

[0055] (1) Determine the types of fibers in the blended yarn respectively hemp fiber and cotton fiber, wherein the hemp fiber mass percentage content X 麻纤维 10%, cotton fiber mass percentage X 棉纤维 90%;

[0056] (2) Hemp fiber is a short fiber. The uniformity of hemp fiber pure spinning single yarn and the number of fibers in the cross section are more difficult to control than cotton pure spinning single yarn. Therefore, hemp fiber is selected as the reference fiber. The average bulk density of hemp fiber ρ 麻纤维 1.52g / cm 3 , the average cross-sectional area S of hemp fiber 麻纤维 π×(15μm) 2 ; The average bulk density ρ of cotton fibers 棉纤维 1.54g / cm 3 , the average cross-sectional area S of cotton fibers 棉纤维 π×(10μm) 2 , according to the formula N 棉纤维 / N 麻纤维 =(X 棉纤维 ×S 麻纤维 ×ρ 麻纤维 ) / (X 麻纤维 ×S 棉纤维 ×ρ 棉纤维 ), to obtain the root number ratio N of cotton ...

Embodiment 3

[0063] A method for preparing blended yarn with evenly distributed component content, comprising the following steps:

[0064] (1) Determine that the types of fibers in the blended yarn are respectively viscose fiber, wool fiber and acrylic fiber, wherein the viscose fiber mass percentage content X粘胶纤维 30%, wool fiber mass percentage X 毛纤维 40%, acrylic fiber mass percentage X 腈纶纤维 30%;

[0065] (2) Wool fiber is a short fiber, and the uniformity of wool fiber pure spinning single yarn and the number of fibers in the cross section are the most difficult to control. Therefore, wool fiber is selected as the reference fiber, and the average volume density of wool fiber ρ 毛纤维 1.34g / cm 3 , the average cross-sectional area S of the wool fiber 毛纤维 π×(25μm) 2 ; Average bulk density ρ of viscose fibers 粘胶纤维 1.55g / cm 3 , the average cross-sectional area S of the viscose fiber 粘胶纤维 π×(10μm) 2 ; Average bulk density ρ of acrylic fibers 腈纶纤维 1.18g / cm 3 , the average cross-sectiona...

Abstract

The invention discloses a preparation method of blended yarn with uniform component content distribution. The method comprises the following steps: (1) determining the type and mass percentage contentof fibers in the blended yarn; (2) selecting one of the fibers in the blended yarn as a reference fiber, and respectively obtaining the number ratio of other fibers to the reference fiber, namely N[other fibers] / N[reference fiber], according to the mass percentage content Xn, the average volume density [rho]n and the average cross sectional area Sn of a fiber n in the blended yarn; (3) determining the number N[reference fiber] of the reference fiber, and respectively obtaining the number N[other fibers] of other fibers according to the number ratio of other fibers to the reference fiber, namely, N[other fibers] / N[reference fibers]; (4) determining the number Mn of pure-spun single yarns of the fiber n according to the number Nn of the fiber n; and (5) untwisting the pure-spun single yarnsof different fibers, and performing combining and twisting to form the blended yarn. The preparation method provided by the invention can be used for quickly and accurately preparing the blended yarnwith uniform component content distribution.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a method for preparing a blended yarn with uniform component content distribution. Background technique [0002] At present, there are two main sources of standard yarns for multi-component blending: one is to use the traditional spinning process to compress the fiber package of multi-component fibers according to a certain ratio, and place them under the catching machine to capture microfibers Bundle, followed by uniform mixing, carding, drawing, roving and spun yarn, and finally winding; the second is to select from the current market samples in Shanghai, and then use the chemical dissolution method to obtain a reference multi-component blended yarn. [0003] From the above methods, the current multi-component fiber blended yarn preparation method has the following deficiencies: (1) traditional production equipment requires at least 5 or more cotton bales, each with more than ...
