Description

Technical Field

[0001] This invention relates to the field of fabric weaving technology, specifically to a weaving process for a cashmere-like interwoven fabric. Background Technology

[0002] Interwoven fabrics are made by interlacing two or more different types of yarns through a warp and weft interlacing process. The warp and weft yarns use yarns of different materials, resulting in a unique texture and feel on the fabric surface, creating a sense of visual depth.

[0003] In the existing technology, the color fastness of interwoven fabrics to washing is usually grade 3-4, which makes them prone to fading or staining. In addition, the dimensional stability of the wash is usually ±1% to ±3%, which will cause certain dimensional deformation during use. At the same time, the pH value of the fabric is usually 4.0 to 9.0, which can irritate the skin to some extent. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this application proposes a cashmere-like interwoven fabric weaving process. The fabric has a soft and supple feel like cashmere, effectively prevents fading and staining, significantly reduces dimensional deformation, and minimizes skin irritation.

[0017] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Example like Figure 1 and Figure 2 As shown, a cashmere-like interwoven fabric weaving process includes the following steps: S1. The first yarn and the second yarn are twisted together without twisting. The first yarn is 50S / 1 Lenzing cyclic viscose yarn and the second yarn is 32S / 1 recycled polyester yarn. S2. Twist the first and second yarns after untwisted yarns are combined. The first yarn is twisted to 600 twists / meter in the S direction, and the second yarn is twisted to 500 twists / meter in the S direction. S3. Dye the twisted first yarn and the second yarn separately, wherein the first yarn is dyed at 60 degrees Celsius and the second yarn is dyed at 130 degrees Celsius. S4. Warp the dyed yarn to a total of 4658 warp ends and a warp beam width of 171cm. S5. The warped yarn is woven in three widths at a speed of 320 rpm and a weft density of 26.58 shuttles / cm. S6. Twist the woven fabric into ropes with a rope spacing of 1.4cm / rod. S7. Soften the fabric after rope twisting by using a fabric softener and silicone oil, with a steam pressure of 5.4-5.6KG on the roller. S8. Punch the softened fabric until short pile appears on the surface. S9. Calender the fabric after burring, with a steam pressure of 4.5KG on the roller; S10. Cut and trim the cords on the calendered fabric, leaving 0.3-0.5cm fringes on both sides and 9cm cords at both ends.

[0019] In step S1, the first yarn and the second yarn are twisted together without twisting, wherein the first yarn is 50S / 1 Lenzing cyclic viscose yarn and the second yarn is 32S / 1 recycled polyester yarn, including the following steps: S101. The first yarn is twisted and spun into yarns without twisting. The first yarn is 50S / 1 Lenzing cyclic viscose yarn. Two 50S / 1 Lenzing cyclic viscose yarns are twisted together without twisting. Here, 50S / 1 indicates that the fineness of each single yarn is 50 count. Lenzing cyclic viscose yarn is a regenerated cellulose fiber with environmentally friendly and low static electricity characteristics. It is twisted together without twisting using a GD102 type twisting machine.

[0020] S102. The second yarn is untwisted and filamented; The second yarn is 32S / 1 recycled polyester yarn. Two 32S / 1 recycled polyester yarns are twisted together without twisting. Here, 32S / 1 indicates that the fineness of each single yarn is 32 count. Recycled polyester yarn is a recycled fiber with high strength and moisture absorption and breathability. It is twisted together without twisting using a GD102 type twisting machine.

[0021] In step S2, the first and second yarns after untwisted spinning are twisted respectively. The first yarn is twisted to 600 twists / meter in the S direction, and the second yarn is twisted to 500 twists / meter in the S direction. This includes the following steps: S201. Twist the first yarn after untwisted yarn to 600 twists / meter, twisting in the S direction; Two strands of untwisted 50S / 1 Lenzing cyclic viscose yarn are twisted to 600 twists / meter, with the twist direction being S-axis and the fibers tilting from the lower right to the upper left. The yarn is then twisted using a yarn doubling machine.

[0022] S202. Twist the second yarn after untwisted yarn to 500 twists / meter, twisting in the S direction; Two strands of untwisted 32S / 1 recycled polyester are twisted to 500 twists / meter, with the twist direction being S-axis and the fibers tilting from the lower right to the upper left. The yarn is then twisted using a yarn doubling machine.

[0023] In step S3, the twisted first yarn and the second yarn are dyed separately, wherein the first yarn is dyed at 60 degrees Celsius and the second yarn is dyed at 130 degrees Celsius, including the following steps: S301. Dye the twisted first yarn at 60 degrees Celsius; The twisted 50S / 2 Lenzing cyclohexene viscose is placed in a high-temperature and high-pressure dyeing machine for yarn cones and dyed at 60 degrees Celsius. This environmentally friendly dyeing method is suitable for the gentle dyeing of Lenzing cyclohexene viscose, which can ensure dye penetration and avoid damage to the fibers from high temperature.

[0024] S302. Dye the twisted second yarn at 130 degrees Celsius; The twisted 32S / 2 recycled polyester yarn is placed in a high-temperature and high-pressure dyeing machine for yarn cone dyeing. It is then dyed at a high temperature of 130 degrees Celsius in an environmentally friendly manner to relax the fiber structure, promote the diffusion of dye molecules into the fiber interior, and improve the dyeing rate.

[0025] In step S4, the dyed yarn is warped, with a total of 4658 warp ends and a warp width of 171cm, including: The dyed yarn was warped using an HF988C slitting and warping machine, with a total of 4658 warp ends and a warp beam width of 171cm.

[0026] In step S5, the warped yarn is woven in three widths at a machine speed of 320 rpm and a weft density of 26.58 shuttles / cm, including: The warped yarn is woven in three widths using a 190cm Ita R880 high-speed rapier loom. The jacquard head is a rectangular 5120 needle jacquard head, the machine speed is 320 rpm, and the weft density is 26.58 shuttles / cm.

[0027] In step S6, the woven fabric is twisted into ropes with a rope spacing of 1.4cm / rod, including: The woven fabric is twisted using a 1000-type rope twisting machine with a spacing of 1.4cm per rope, ensuring no rope is missed during threading.

[0028] In step S7, the fabric after rope twisting is softened using a fabric softener and silicone oil, with a steam pressure of 5.4-5.6 kg on the rollers, including: The 2C-2000 softening and ironing finishing machine is used to soften the fabric after twisting. The roller steam pressure is 5.4-5.6KG, which promotes the penetration of the softener and reduces the shrinkage rate of the fabric. The mixture consists of 450 liters of water, 3 liters of fabric softener, and 0.82 liters of silicone oil, with a fabric softener bath ratio of 150:1 and a silicone oil bath ratio of 550:1.

[0029] In step S8, the softened fabric is napped until short fibers appear on the surface, including: The softened fabric is burred using a burring machine. The burring parameters are adjusted to a heavy burring setting until short pile appears on the fabric surface without affecting the clarity of the fabric pattern. The height of the short pile is less than or equal to 3mm.

[0030] In step S9, the fabric after burring is calendered under a steam pressure of 4.5 kg, including: The fabric after burring is flattened and straightened using a calender, with a roller steam pressure of 4.5KG, balancing the flattening effect with the risk of fiber damage.

[0031] In step S10, the calendered fabric is cut and the cords are trimmed, leaving 0.3-0.5cm tassels on both sides and 9cm cords at both ends. Cut and trim the cords on the calendered fabric, leaving 0.3-0.5cm frayed edges on both sides and 9cm cords at both ends, with the frayed edges aligned and the cords of equal length at both ends.

[0032] The fabric of this invention underwent performance testing, including: color fastness to washing, dimensional stability during washing (length), dimensional stability during washing (width), and pH value. The test results are shown in Table 1.

[0033] Table 1. Fabric Performance Test Table.

[0034]

[0035] As shown in Table 1, the fabric has a wash fastness of 4-5, which is significantly lower than the 3-4 of conventional fabrics, effectively preventing fading and staining; its dimensional stability during washing is ±0.3% in length and ±0.5% in width, which is significantly lower than the ±1% to ±3% of conventional fabrics, reducing dimensional deformation; and its pH value is 6-7, which is generally neutral, which is significantly lower than the pH value of 4.0 to 9.0 of conventional fabrics, effectively reducing skin irritation.

[0036] In this invention, the fabric has a soft, cashmere-like feel, effectively preventing fading and staining, significantly reducing dimensional deformation, and minimizing skin irritation.
