A process for the production of paper tape fancy yarn products

Abstract

The present application prepares the fancy spun yarn product by the paper tape yarn, the piece-dyed cotton and the cashmere roving through each process. Not only the defects of weak strength of the paper tape yarn can be avoided, but also the functions of light quality, moisture removal, odor elimination and anti-static of the paper tape yarn can be reserved. The textile product which causes the human allergic reaction and the environmental pollution and the like problems can be effectively replaced. The fabric obtained by using the spun yarn product can greatly improve the heat preservation property of the fabric due to the hollow layer. In winter, the warmth-keeping effect can be greatly improved by wearing the paper yarn clothes and only wearing the overcoat outside. Meanwhile, the fancy spun yarn can compensate the uneven yarn count problem between the paper tape yarn bobbins by the piece-dyed cotton, and the spray wool can enhance the stereoscopic sense of the cashmere, make the hand feeling soft, increase the hazy sense on the visual effect, and improve the product grade. The development of the paper tape yarn leads the development of the paper tape composite yarn, and promotes the development of the industry.

Description

Technical Field

[0001] This invention relates to the field of textile products technology, and in particular to a production process for paper tape fancy yarn products. Background Technology

[0002] Washi paper yarn, also known as washi paper, is a traditional name for paper woven from tree fibers. Yarn made from washi paper is called washi yarn. In the past, low-lying tree branches were cut, soaked, and the outer bark was removed to obtain the tough, flexible inner bark. This inner bark was then mashed and broken down into a solution, mixed with resin, to obtain a paste-like pulp. The pulp was then shaken and agitated on a mesh sieve to evenly distribute it, forming a thin sheet of paper, which was then dried to obtain washi paper. Washi paper was then cut into narrow strips, which were folded or twisted to obtain folded washi yarn, twisted washi yarn, or washi paper strips. These have the functions of absorbing and controlling moisture and eliminating odors, and are also resistant to mold and fleas, venting harmful gases, and not generating static electricity. In addition, due to its good breathability, the fabric has a linen-like feel, making it cool to wear in summer and warm in winter, making it a comfortable fabric for all seasons.

[0003] Application number CN202010313305.3, entitled "Invention Application for a Fancy Yarn Production Process," discloses a fancy yarn production process. The steps include: winding nonwoven fabric; slitting on a large cutter; cutting and slitting on a slitting machine; combining and twisting the slitting material into "paper tape fancy yarn" on a twisting machine; setting the yarn in a boiler; winding it onto a pagoda-shaped paper tube using a winding machine; and shrink-packing it into a finished product. This specific process design changes the traditional yarn production process. "Paper tape fancy yarn" is characterized by being environmentally friendly, formaldehyde-free, soft, lightweight, skin-friendly, and available in long lengths. It can be combined with other yarns to create fashionable clothing and fabrics according to customer clothing designs. "Special paper tape fancy yarn" can be directly made into sweaters, scarves, hats, gloves, socks, circular knitting fabric, shuttle knitting fabric, and flat knitting fabric, etc., and has the advantages of simple process steps and strong operability.

[0004] In the existing technology, these so-called "paper tape fancy yarns" are not paper tape yarns in the true sense. Paper tape yarns are lignocellulose fiber yarns, not non-woven fabrics cut from paper as used in the existing technology. Due to the low strength and lower breaking elongation parameters of paper yarns compared to other fibers, the development of paper tape yarns is limited, making it impossible to obtain a spun yarn product that can meet both strength requirements and the characteristics of paper tape yarns. Summary of the Invention

[0005] This invention addresses the shortcomings of existing technologies by providing a production process for paper tape fancy spun yarn products that can retain the characteristics of paper tape yarn while ensuring the strength of the spun yarn products.

[0006] To solve the above-mentioned technical problems, the present invention provides a production process for paper tape fancy yarn products, characterized by comprising the following steps: Step 1: Material preparation: Use a flat paper tube to wind up the paper tape yarn, cashmere roving, and 1 / 30 Ne section dyed cotton according to the required proportions. Step 2: Loading: Place the paper tape yarn bobbin on the loading rack, keep the bobbin vertical, control the paper tape yarn twist to 0, set the cashmere roving bobbin and 1 / 30Ne section dyed cotton bobbin on the yarn rack, and place the cashmere roving on the drafting mechanism. Step 3: Spraying wet the paper tape yarn; Step 4 Semi-finished yarn: The paper tape yarn and 1 / 30Ne space-dyed cotton are fed into the spinning machine and twisted together. The cashmere roving is used as the decorative yarn to obtain the semi-finished single yarn. After winding and coiling with a winding machine, it is ready for use. The space-dyed cotton can make up for the uneven yarn count between the paper tape yarn. Step 5: The semi-finished single yarn from Step 4 is processed into a belt using a belt-making machine; Step 6: Spraying cashmere roving on the drafting mechanism is drafted to make it fluffy. The fluffy cashmere roving is then sprayed through a nozzle into the belt formed by the semi-finished single yarn processing to produce finished yarn. Spraying cashmere can enhance the three-dimensionality of cashmere and make it soft to the touch. Step 7 Packaging: After the yarn is wound by the winding machine, the finished yarn is wrapped with shrink film and shrunk for packaging.

[0007] In the above scheme, the width of the paper yarn used in step 1 is 2-3mm and the thickness is 0.008-1mm. This specification of paper yarn has a certain strength while retaining the characteristics of being lightweight and soft.

[0008] In the above scheme, in step 3, the spray humidity of the paper tape yarn is 30% to 40%.

[0009] In the above scheme, in step 4, the twist of the semi-finished yarn is 200 to 300 twists. If the twist is too low, the twist of the single yarn will be poor and the strength will be poor. If the twist is too high, the single yarn will feel stiff and affect the softness of the cashmere.

[0010] In the above scheme, in step 5, the tape machine uses a 12-cylinder, 3-needle arrangement.

[0011] In the above scheme, the strip in step 5 has a mesh structure that can form an internal space, which helps to make the cashmere more three-dimensional and visually better after spraying.

[0012] In the above scheme, the mesh size of the mesh structure is controlled at 2-3mm.

[0013] In the above scheme, in step 6, the air pressure of the nozzle is 0.3 to 0.5 MPa.

[0014] In the above scheme, the mass percentages of paper tape yarn, space-dyed cotton, and cashmere roving in the finished yarn obtained in step 6 are 15:65:20.

[0015] Compared with existing technologies, this invention has the following beneficial effects: By processing paper tape yarn, space-dyed cotton, and cashmere roving through various processes to produce fancy spun yarn products, it not only avoids the weakness of paper tape yarn but also retains its lightweight, moisture-wicking, odor-eliminating, and anti-static functions; it effectively replaces textiles that cause allergic reactions and environmental pollution. Fabrics made with this type of yarn have significantly improved insulation due to their hollow core. In winter, wearing paper tape yarn clothing only requires layering an outer garment for enhanced warmth. Furthermore, this fancy spinning method uses space-dyed cotton to compensate for uneven yarn counts in paper tape yarn packages, while the spraying enhances the three-dimensional feel of cashmere, making it softer to the touch and adding a hazy visual effect, thus elevating the product's quality. The development of paper tape yarn leads the development of paper tape composite yarns, promoting the industry's growth. Detailed Implementation
