Description

Technical Field

[0001] This invention belongs to the field of textiles, and specifically relates to a method for spinning fancy boucle yarn by mixing fibers and yarns. Background Technology

[0002] The information disclosed in this background section is intended only to enhance understanding of the overall background of the invention and is not necessarily to be construed as an admission or in any way implying that such information constitutes prior art known to those skilled in the art.

[0003] Most boucle yarns on the market are single-state fiber or yarn boucles, which are relatively simple in form and lack a sense of depth and layering. Summary of the Invention

[0004] This invention provides a method for spinning fancy boucle yarn using a blend of fibers and yarns. The invention uses a cotton yarn and a fluffy wool fiber roving as finishing yarns, fed simultaneously, with an elastic nylon filament used as the core and pressing yarn. The resulting boucle yarn has tightly packed and firm cotton boucles, while the wool boucles are fluffy and soft. The boucle yarn undergoes a two-bath dyeing process, utilizing the different dyeing techniques for cotton and wool fibers to dye the two fibers the same, similar, or complementary colors, creating a series of vibrant colors. The overlapping of large and small boucles in the yarn forms a staggered and three-dimensional texture, and the unique color mixing effect showcases a multi-layered color appearance.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A first aspect of the present invention provides a method for spinning fancy boucle yarn by blending fibers and yarns, comprising:

[0007] Fiber-type roving is prepared using wool as raw material;

[0008] Yarn-type decorative yarns are prepared using cotton as raw material;

[0009] In the fancy twisting machine process, a wool roving is output from the front roller through the drafting mechanism, and another cotton yarn is output from the drafting cradle through pretension and also from the front roller at the same time. Together they meet with the two nylon filaments sent out by the core roller. The false twist generated by the rotation of the hollow spindle wraps the decorative yarn around the core yarn to form a preliminary pattern. The fixed yarn is a nylon filament that is wrapped around the fixed yarn tube outside the hollow spindle. Thus, the fiber-type wool roving, the yarn-type cotton yarn, the double-core nylon filament and the fixed nylon filament pass through the hollow spindle in parallel, and are wrapped around the twisting hook to form a secondary twist. Together they are driven by the output roller to complete the loop yarn through the winding cylinder.

[0010] The boucle yarn is spun into strands, and after the strands are dyed, iridescent boucle yarn is obtained.

[0011] In some implementations, the raw material is Australian wool with a fineness of 18.5±0.3um and a length of 50-60mm.

[0012] In some embodiments, the cotton is specified as: 100% cotton 51NM / 1 natural white.

[0013] In some embodiments, the wool blending process includes: adding 1% wool oil, 2.5% antistatic agent, and 7.5%-9% water to the wool, with the water temperature controlled at 35℃-40℃, and curing for 24-48 hours, wherein each percentage is based on the weight of the wool.

[0014] In some embodiments, the dyeing process includes: pretreatment and two-bath dyeing.

[0015] In some embodiments, the specific conditions for the pretreatment are: adding 1-3% of degreasing and leveling agent, 1-3% of penetrant, heating to 70°C and running for 30 minutes, then cooling and rinsing clean.

[0016] In some embodiments, the yarn-shaped loops for dyeing cotton are as follows: liquor ratio 1:8, temperature 30-40℃, X% of reactive dye is poured into the chemical tank and fully dissolved, then slowly added to the dyeing tank, run for 10 minutes, add 10-60 G / L sodium sulfate in batches, temperature 60℃, keep warm for 20-40 minutes, add 10-20 G / L soda ash in batches, keep warm for 20-60 minutes; cool down and rinse, soap, pass acid, and rinse again.

[0017] In some embodiments, dyeing wool fiber loops involves: adding water and heating to 30-40°C, adding 1-2% Abbey FFA, 1-2% Abbey B, and 1-2 G / L formic acid and running for 10 minutes, adding X% Lanners dye and running for 10 minutes, raising the temperature to 60-80°C at 1°C / min and holding for 10 minutes, then raising the temperature to 98°C at 1°C / min and holding for 30-60 minutes; cooling and rinsing, alkaline washing, and rinsing thoroughly with clean water; adding 2% softener and 0.5 G / L formic acid and running for 20 minutes, draining the water and drying.

[0018] A second aspect of the invention also provides fancy boucle yarn prepared by the above-described method.

[0019] Beneficial effects of the present invention

[0020] (1) This invention is a novel and fashionable yarn that not only retains the advantages of cotton fiber—good moisture absorption, strong breathability, and stable performance—but also has the soft hand feel and good loft of wool. The complementary advantages of the two fibers result in a rich variety of colors and highlight the dynamism of the loop pattern. It is particularly in line with the concept of fashionable clothing design, and this yarn has been well received by the market since its launch.

[0021] (2) The fluffy and lightweight texture of the yarn fabric of the present invention can be used as early spring H-shaped cardigans, casual vests, and versatile round necks; it can also be used in circular knitting and woven fabrics, providing more materials for the use of fancy yarns and giving the design a more distinct casual texture.

Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0030] The present invention will be further described in detail below with reference to specific embodiments. It should be noted that the specific embodiments are explanations of the present invention and not limitations thereof.

[0031] In the following examples, all raw materials and reagents are commercially available products.

[0032] Example 1

[0033] I. Method for preparing fibrous roving

[0034] 1. Raw material selection and wool blending process

[0035] The wool selected is Australian wool with a fineness of 18.5±0.3um and a length of 50-60mm. To ensure that the wool fibers form round loops and reduce the short fibers exposed outside the yarn, the short fiber rate of the wool top with a length of less than 20mm is controlled to be within 4%.

[0036] Considerations for wool blending process: During the combing process, wool not only bears the effects of opening and combing, but also the friction and tension applied by other combing elements. These effects can damage the wool scales. In order to reduce fiber damage, additives must be added during blending to form a protective oil film on the fiber surface, which provides good lubrication.

[0037] Specific process: According to the weight ratio of wool, add 1% wool oil, 2.5% antistatic agent, and 7.5%-9% water, and control the water temperature at 35℃-40℃, and cure for 24-48 hours.

[0052] III. Flower Twisting

[0053] In the fancy twisting machine process, a wool roving is output from the front roller via the drafting mechanism, while another cotton yarn, after pretensioning at the drafting cradle, is also output from the front roller simultaneously. Together, they meet the two nylon filaments fed from the core roller. The false twist generated by the rotation of the hollow spindle wraps the decorative yarn around the core yarn, forming a preliminary pattern. A fixed nylon filament comes from the fixed yarn tube surrounding the hollow spindle. Thus, the fiber-type wool roving, the yarn-type cotton yarn, the double-core nylon filament, and the fixed nylon filament pass parallel through the hollow spindle, wrapping once on the twisting hook to form a secondary twist. Together, they are driven by the output roller through the winding cylinder to complete the looped yarn process. Figure 4 As shown.

[0054] IV. Yarn dyeing

[0055] Loop yarn is spun into skeins, each skein weighing 250 grams, and then the skeins are prepared for dyeing.

[0056] 1. Pretreatment: Add 1-3% degreasing and leveling agent and 1-3% penetrant, heat to 70℃ and run for 30 minutes, then cool and rinse clean.

[0057] 2. Dyeing: To obtain colorful AB rings, a two-bath dyeing process is used.

[0058] A. Dyeing cotton yarn loops: Use a liquor ratio of 1:8 and heat to 30-40℃. Dissolve X% of the reactive dye in the chemical tank, then slowly add it to the dyeing tank. Run for 10 minutes. Add 10-60g / L of sodium sulfate in batches. Heat to 60℃ and maintain the temperature for 20-40 minutes. Add 10-20g / L of soda ash in batches and maintain the temperature for 20-60 minutes. Cool, rinse, soap, acidify, and rinse again.

[0059] B. Dyeing wool fiber loops: Add water and heat to 30-40℃. Add 1-2% Abberg FFA, 1-2% Abberg B, and 1-2g / L formic acid and run for 10 minutes. Add X% Lanner dye and run for 10 minutes. Increase the temperature at 1℃ / min to 60-80℃ and hold for 10 minutes. Then increase the temperature at 1℃ / min to 98℃ and hold for 30-60 minutes. Cool down, rinse, perform an alkaline wash, and rinse thoroughly with clean water. Add 2% softener and 0.5g / L formic acid and run for 20 minutes. Drain and dry.
