Description

Technical Field

[0001] This invention relates to the field of textile technology, and more particularly to the weaving of a napped yarn. Background Technology

[0002] Cashmere fiber is a rare animal fiber, highly favored for its superior properties, and has always been the preferred fiber for high-end textiles. The trend towards lighter and thinner textiles worldwide means that cashmere fiber, with its fineness and soft, smooth texture, will continue to appeal to consumers.

[0003] Over the past three or four decades, fancy yarns have been applied to virtually every aspect of our lives. They are made into clothing or used to decorate people's living environments, bringing warmth and comfort. The applicant has specifically developed a new type of cashmere yarn for iridescent cashmere products. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies by providing a method for preparing suspended segment colored cashmere yarn. This application presents a novel type of cashmere brushed yarn, in which the suspended segment colored cashmere yarn displays different colors from different angles under natural conditions, resulting in a very vibrant effect. Combined with the soft feel of cashmere itself and the dazzling colorful patterns, this invention enhances the commercial value of the product and further increases the added value of cashmere products.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a method for preparing suspended segment colored cashmere yarn, comprising the following steps: Step A: Selecting cashmere fibers with a fineness of 15.5 micrometers to 16.5 micrometers and a length of 32 millimeters to 34 millimeters, and then dyeing the cashmere fibers to obtain at least two different colors of cashmere fibers; Step B: Performing wool-making on the cashmere fibers of different colors, with the wool-making process being the same for all colors, i.e., the feed amount and layer thickness are controlled within 15 cm during wool-making, the number of turning times is more than 2, and then a diluted wool-making agent is evenly sprayed, and the mixture is left to stand for at least 24 hours, with the moisture regain on the machine controlled within 20±1% during wool-making; Step C: Combing the cashmere fibers of different colors, with the combing process being the same for all colors, involving a pin combing-combing-first pinning-second pinning-third pinning-fourth pinning process; Step D: Drafting the cashmere fibers of different colors into rovings. During the processing, the evenness CV% is controlled below 6%, and the count of different colored goat rovings is the same and between 2Nm and 6Nm; Step E: Select different colored goat rovings and iridescent silk as decorative yarns, that is, the decorative yarn has three strands, and the silk is used as the core and fixing yarn. The yarn is produced by a fancy twisting machine. During the production process, the decorative yarn is arranged in the order of goat roving-iridescent silk-goat roving and fed in at the same time. When feeding, the order of the rovings on the left and right sides is consistent on each spindle. The iridescent silk in the middle passes through the back tension plate and then through the back mountain type. Step F: Feed the yarn through the frame and front roller without passing through the drafting zone, so that the iridescent yarn appears to be covered by goat roving; Step G: Use a skein yarn raising machine or a cone yarn raising machine to raise the yarn lightly until the iridescent yarn is clearly visible; Step H: Steam the yarn at 80℃ for at least 30 minutes using a double-cycle steaming process; Step H: Rewind the yarn at a speed of less than 300 meters per minute, and clean the yarn after rewinding. After cleaning, wax the yarn.

[0006] In the above technical solution, preferably, in step B, the wool-refining agent comprises 2.5% FX-906 wool oil and 1.5% FX-AS301 antistatic agent by mass percentage.

[0007] In the above technical solution, preferably, in step D, the count of the goat roving of different colors is 4Nm.

[0008] In the above technical solution, preferably, in step E, the yarn count of the napping yarn is above 20Nm, the inner twist is 500-700 twists / meter with a twist direction of "Z", and the outer twist is 200-800 twists / meter with a twist direction of "S", to ensure that the yarn does not twist.

[0009] In the above technical solution, preferably, in step F, the overfeed ratio is between 1.5 and 2.5.

[0010] In the above technical solution, preferably, in step E, the core wire is Ne2 / 120 silk and the fixing wire is Ne2 / 60 silk.

[0011] In the above technical solution, preferably, in step E, the iridescent yarn is a monochrome or multicolor iridescent yarn with polyester as the base, or a photochromic iridescent yarn with polyester as the base.

[0012] In the above technical solution, preferably, in step H, the unwinding process begins 3 minutes after the steaming process ends and the room temperature cools down.

[0013] In the above technical solution, preferably, in step E, the color of the iridescent silk is an intermediate color between different colors of goat roving.

[0014] The suspended segment colored cashmere yarn in this application is a variant of brushed yarn, which mainly exhibits rich color variations under different viewing angles. The main colors of this suspended segment colored cashmere yarn include two aspects: firstly, the different colors of cashmere fibers, and secondly, the colors of the iridescent yarn. Iridescent yarn can be monochrome, multicolor, or photochromic. To achieve a good "floating" visual effect, iridescent yarn requires photochromism. During the twisting process, the yarn is arranged in the order of cashmere roving - iridescent yarn - cashmere roving and fed in simultaneously, allowing the colors to be layered and the iridescent yarn to appear as if it is covered by the cashmere roving. Since the cashmere yarns on both sides of the iridescent yarn are different colors when fed in, the iridescent yarn changes color due to the change in brightness as the yarn rotates. At this time, since the iridescent yarn appears to be covered, the colors can be regarded as being divided into multiple layers. The color layers can be regarded as the first layer of cashmere color - iridescent yarn color - the second layer of cashmere color. Each adjacent layer of color has a color difference. When the second layer of iridescent yarn color changes color, the contrast between the first layer of cashmere color and the second layer of cashmere color suddenly becomes strong, presenting a "floating effect" at both ends. Theoretically, the "floating effect" only occurs when the iridescent yarn changes color. However, during normal wear, the "floating" effect will always appear due to the movement of the body or limbs, making the garment very beautiful when actually worn.

[0015] The core technical points of this application include: 1. Using two colors of worsted cashmere raw materials, combined with iridescent silk. 2. Using a twisting machine to produce two-color segmented cashmere boucle yarn. 3. Producing iridescent brushed cashmere yarn through a brushing machine. 4. By controlling different colored rovings in the front and back drafting stages, different color segments are presented on the yarn, making the yarn dazzling and colorful.

[0016] This application utilizes the soft, smooth feel of cashmere products to create looped patterns, paired with iridescent silk as the core yarn, and employs a two-tone iridescent yarn woven from two-tone roving to enrich the style of the cashmere product. We select two colors of roving yarn as finishing yarns, and the combination of the two colors needs to be soft, making this product lively and vibrant. This application adheres to the principle of being light, warm, soft, and supple with a good body. The inner and outer twist are determined based on the yarn count and the appearance of the loops, ensuring no twisting and elasticity. The twist is set at a medium-low twist, with the inner twist controlled at around 600T / m.

[0017] The specific process of this application includes: initial brushing – combing – fine combing – first needle – second needle – third needle – fourth needle – worsted untwisted roving – twisting – napping – steaming – winding. This application uses roving produced via a conventional worsted cashmere roving production route, employing two colors as decorative yarns, and adding iridescent yarns to the decorative yarn column. Ne2 / 120 silk is used as the core yarn, and Ne2 / 60 silk as the binding yarn to complete the yarn production. The production of cashmere roving follows a conventional worsted production route, primarily controlling the roving evenness (cv%) and yarn count at Nm4. Because two-color roving is used as decorative yarn, the yarn counts of the two colors need to be controlled by yarn count deviations in the same direction. This application uses three decorative yarns produced simultaneously, requiring consistent left and right roving spindle order during production. Simultaneously, the iridescent yarn must pass through the back tension plate, the back drafting frame, and then be fed in via the front roller without passing through the drafting zone.

[0018] Compared with existing technologies, this application presents a novel cashmere brushed yarn. The suspended segment colored cashmere yarn in this application displays different colors from different angles under natural conditions, creating a stunning effect. Combined with the soft feel of cashmere itself and the vibrant color patterns, this application's product boasts high commercial value, further enhancing the added value of cashmere products.
