AI Technical Summary
In existing technologies, the scales are easily damaged when Tencel and wool fibers are blended, resulting in a high yarn breakage rate, defects during weaving, poor flexibility in color combinations, and difficulty in responding quickly to market changes.
Using the optimal ratio of 82% Tencel and 18% wool, the yarn is formed by twisting and plying to create AB two-color yarn. Only the Tencel fibers are dyed, while the wool fibers retain their original color. Combined with slitting and warping and an optimized weaving environment, the sizing process is avoided, and reactive dyes are used for dyeing under alkaline conditions.
It achieves a perfect combination of the performance of Tencel and wool, improves the stability of the fabric and the quality of the yarn, reduces the yarn breakage rate, enhances the flexibility of color combinations, reduces wastewater discharge, meets the requirements of green manufacturing, and the fabric has a full and elastic feel.

Abstract
Description
Technical Field
[0001] This invention relates to the field of textile fabric technology, and in particular to a Tencel wool AB two-color yarn. Background Technology
[0002] With the upgrading of consumption, the market demand for high-end textiles that combine luxury, comfort, ease of care, and functionality is growing. Tencel (Lyocell) fiber has excellent breathability, moisture absorption, and silky luster, but when used alone, the product lacks a sense of structure and has low wet strength; wool fiber is known for its warmth, elasticity, and noble texture, but it is prone to severe shrinkage due to the entanglement of its scale structure in humid and hot environments.
[0003] Existing technologies include blending Tencel, wool, and cotton fibers, but these methods typically require sizing during weaving and desizing and dyeing in the finishing process, which is lengthy and environmentally unfriendly. Another technique involves dyeing the wool tops separately with reactive and acid dyes before spinning. However, this process damages wool scales and Tencel strength, leading to increased yarn breakage, uneven yarn texture, and defects such as weaving streaks and color streaks. Furthermore, it lacks flexibility in color combinations, making it difficult to respond quickly to market changes. Summary of the Invention
[0004] The purpose of this invention is to provide a Tencel-wool AB two-color yarn, which perfectly combines the breathability, moisture absorption, smoothness and dimensional stability of Tencel with the warmth, elasticity and luxury of wool through the optimal ratio of 82% Tencel and 18% wool. The introduction of Tencel effectively inhibits the felting and shrinkage tendency of wool and improves the overall stability of the fabric.
[0005] To achieve the objective of this invention, this invention provides a Tencel-wool AB two-color yarn, comprising: a single yarn of two different colors, A and B, woven together and twisted; the single yarn of the Tencel-wool blend is made of 82% Tencel fiber and 18% wool fiber; the two colors A and B are formed by dyeing the blended single yarn, wherein only the Tencel fiber component is dyed while the wool fiber component remains white.
[0006] As a preferred embodiment of the present invention, the Tencel fiber is antigen-fibrillated Tencel LF fiber.
[0007] As a preferred technical solution of the present invention, the blended single yarn is a Tencel wool blended S-twist single yarn spun into a yarn with uniform evenness and few fine details; the plying and twisting is to ply and twist the dyed A-color yarn and B-color yarn on a twisting machine with Z-twist, and the plying twist coefficient is 350-370.
[0008] This invention provides a method for producing Tencel wool AB two-color yarn fabric, comprising the following steps:
[0009] Warping process: The Tencel wool AB two-color yarn is used as the warp yarn and warped using a sliver warping process. The warping displacement is 1.0-1.5mm, and no sizing is required during the warping process, directly forming the warp beam.
[0010] Weaving process: The warp beam obtained in the warping process is woven on a rapier loom. The weaving environment temperature is controlled at 24-26℃ and the relative humidity is controlled at 65%-75%.
[0011] As a preferred embodiment of the present invention, the warping displacement is 1.2 mm.
[0012] As a preferred embodiment of the present invention, the processing method of the Tencel wool AB two-color yarn includes the following steps:
[0013] S1. Blending process: Tencel fiber and wool fiber are blended in a mass ratio of 82:18 and spun into S-twist single yarn.
[0014] S2, Dyeing process: The single yarn obtained in S1 is loosely wound and then dyed with reactive dyes under alkaline conditions, so that the Tencel fibers in the blended yarn are dyed, while the wool fibers basically retain their original color, thus producing A-color yarn and B-color yarn respectively.
[0015] S3. Plying process: The A-color yarn and B-color yarn are twisted together in a Z-twist process on a twisting machine, and the twisting coefficient is controlled within the range of 350-370.
[0016] S4. Setting process: Steam setting is performed on the AB two-color yarn after plying.
[0017] As a preferred embodiment of the present invention, in step S2, the reactive dye used for dyeing is a reactive dye suitable for cellulose fibers.
[0018] Compared with the prior art, the present invention provides a Tencel wool AB two-color yarn, which has the following beneficial effects:
[0019] This invention achieves a perfect blend of 82% Tencel and 18% wool, combining the breathability, moisture absorption, smoothness, and dimensional stability of Tencel with the warmth, elasticity, and luxurious feel of wool. The introduction of Tencel effectively suppresses the felting and shrinkage tendency of wool, improving the overall stability of the fabric. The "single yarn dyeing Tencel" process, which dyes only the Tencel, avoids damage to the wool scales from acidic dyes and mechanical damage from dyeing the wool tops, reducing yarn breakage and improving yarn quality and color consistency. By combining A and B two-color single yarns, the fabric gains a three-dimensional and rich two-color effect with strong visual depth. Furthermore, a variety of color combinations can be derived from a small amount of basic colored yarn, offering high flexibility. The entire weaving process requires no sizing, eliminating the desizing process, reducing water and chemical consumption and wastewater discharge, meeting green manufacturing requirements. Sizing-free weaving preserves the natural softness of the fibers to the greatest extent. Combined with optimized twist and steaming and setting processes, the final fabric has a full and elastic feel, with excellent performance indicators. Detailed Implementation
