Description

Technical Field

[0001] This invention relates to the field of textile technology, specifically to a method for preparing a feather-like yarn down fabric and its products. Background Technology

[0002] Feather-like down fabrics are a new type of textile material that uses chemical fibers to simulate the appearance, feel, and warmth of natural down. They are widely used in high-end thermal clothing, home textiles, and outdoor equipment. Natural down, due to its unique barb-down cluster structure and excellent still air retention, is lightweight, soft, and extremely warm. However, it suffers from limited availability, fluctuating prices, tendency to clump after washing, allergies in some individuals, and animal ethics controversies. Existing fabrics use synthetic fibers such as polyester and nylon, employing finishing processes like combing and spinning to create a downy surface. However, existing feather-like down fabrics made from these fibers suffer from insufficient warmth and significant shedding, failing to meet the performance requirements of the high-end market for natural down substitutes. Summary of the Invention

[0003] The purpose of this invention is to solve the problems of insufficient warmth retention and severe shedding in existing feather-like fabrics, and to provide a method for preparing feather-like fabrics, including the following steps: S1. Raw material preparation: Polyester DTY is used as raw material, including first component, second component and binding yarn. The first component is 150D / 288F, the second component is 150D / 48F, and the binding yarn is 150D / 48F. S2, Weft weaving: The first component, the second component and the binding wire are woven together to obtain a greige fabric; S3, First-time setting: The woven fabric undergoes a first-time setting process; S4. Dyeing and / or printing, drying: Dyeing and / or printing on the greige fabric after the first setting treatment, followed by drying; S5. Secondary shaping: The dried fabric undergoes a secondary shaping process. S6. Finishing: Finishing the greige fabric after the secondary shaping process, including combing. S7. Pelleting: Pelleting the finished greige fabric; S8. Blowing: Blowing the fabric after the granulation treatment. S9. Three-stage setting: The fabric after blown fabric is set three times. In step S5, the conditions for the secondary shaping treatment include: the treatment solution consists of 15-25 g / L of a first softener, 10-20 g / L of a second softener, 5-10 g / L of an organosilicon elastomer, and 1-3 g / L of a penetrant; citric acid is used to adjust the pH of the treatment solution to 5-5.5; and the remainder is water. The first softener is an amino-modified organosilicon softener with a viscosity of 2000-5000 cPs; the second softener is an amino-modified organosilicon softener with a viscosity of 100-300 cPs.

[0004] This invention utilizes a primary setting, a secondary setting, a tertiary setting, and a specific blown fiber treatment process. This process allows the fibers to be fully softened during the secondary setting, creating a stable and fluffy structure within the fibers. Then, precise orientation is achieved through blown fiber treatment. Finally, the roots are reinforced through gradient cross-linking during the tertiary setting. The resulting fabric possesses excellent softness, warmth, and shedding resistance, solving the problems of existing down-like fabrics, such as rough texture, insufficient warmth, and severe shedding.

[0005] In this invention, 150D / 288F polyester can be used to form the pile body, giving the fabric a soft and fluffy biomimetic pile feel, while 150D / 48F polyester DTY can be used to form the base fabric skeleton, providing dimensional stability and structural support. The binding yarn can fix the fibers and prevent pile fibers from falling off. As a preferred embodiment of this invention, the mass ratio of the first component, the second component, and the binding yarn is (65-80):(20-35):(5-15), preferably 75-80:(20-25):(5-10). Controlling the mass ratio of the first component, the second component, and the binding yarn within the above range ensures both good softness of the prepared fabric and dimensional stability and strength of the base fabric.

[0006] As a preferred technical solution of the present invention, in step S2, the weaving is performed using a single-sided circular knitting machine or a double-sided circular knitting machine.

[0007] As a preferred technical solution of the present invention, in step S2, the machine used for weaving is of size E22-E28 and the cylinder diameter is 30-38 inches.

[0008] As a preferred technical solution of the present invention, in step S2, the weaving process adopts plain weave, Roman weave or air layer weave, and the binding wires are interwoven between the first component and the second component.

[0009] As a preferred technical solution of the present invention, in step S2, the basis weight of the woven fabric is 180-350 gsm.

[0010] As a preferred technical solution of the present invention, in step S3, the conditions for the first shaping process include: shaping temperature of 190-200℃, machine speed of 20-35m / min, overfeed of 8%-12%, and fixed width of 105%-110% of the finished width.

[0011] The dyeing and printing in step S4 of this invention can be carried out in accordance with conventional methods in the art as needed. This invention has no special requirements for this, so it will not be elaborated further. The drying in step S4 of this invention can be carried out in accordance with conventional methods in the art as needed, generally controlling the moisture content to ≤5%. This invention has no special requirements for this, so it will not be elaborated further.

[0012] As a preferred technical solution of the present invention, in step S5, the rolling mill pressure is 3-4 bar, the liquid carrying rate is 60%-70%, the overfeed is 10%-15%, the rolling speed is 20-30 m / min, the setting temperature is 170-185℃, and the setting time is 40-60 seconds.

[0013] As a preferred technical solution of the present invention, the first softener is an amino-modified organosilicon softener with a viscosity of 2000-5000 cPs, for example, it can be JF-802A from Jiashan Jiangnan Textile.

[0014] As a preferred embodiment of the present invention, the second softener is an amino-modified silicone softener with a viscosity of 100-300 cPs, such as JF-8052 from Jiashan Jiangnan Textile.

[0015] The penetrant used is FKS.

[0016] The organosilicon elastomer may be cyclopentamethoxysiloxane and polydimethylsiloxane / vinyl polydimethylsiloxane crosslinked polymer from Guangzhou Chuanyi Chemical Co., Ltd.

[0017] That is, as a preferred technical solution of the present invention, the treatment solution used for the secondary shaping treatment is 15-25 g / L of JF-802A from Jiashan Jiangnan Textile, 10-20 g / L of JF-8052 from Jiashan Jiangnan Textile, 5-10 g / L of cyclopentamethoxysiloxane and polydimethylsiloxane / vinyl polydimethylsiloxane cross-linked polymer from Guangzhou Chuanyi Chemical Co., Ltd., 1-3 g / L of penetrant FKS, and citric acid to make the pH value of the treatment solution 5-5.5, with the remainder being water.

[0018] In this invention, the use of a specific treatment liquid and corresponding setting conditions in the secondary setting process enables the fabric to possess better softness and lint resistance. It is speculated that this is because the combination of the first softener, the second softener, and the silicone elastomer ensures both appropriate cross-linking between the softener and the fiber to guarantee wash resistance and avoids high-temperature damage to the fiber.

[0019] The above-mentioned secondary setting process can be carried out according to the conventional process steps in this field. That is, the dried fabric is fed into the padding and impregnation step using a fabric feeder and tension adjusting rollers. The padding pressure is controlled at 3-4 bar, and the liquid content of the fabric after padding is 60%-70%. Then, it enters the overfeed roller and the overfeed is adjusted to 10%-15%. Finally, the speed is controlled at 20-30 m / min and it enters the drying ovens 1-6 for setting. The lengths of drying ovens 1-6 are the same, and the temperatures of drying ovens 1-6 are 173-177℃, 176-179℃, 180-185℃, 180-185℃, 173-177℃, and 170-172℃ respectively. The setting time is 40-60 seconds.

[0020] In this invention, the imitation feather yarn fabric can be selected as either a single-sided or double-sided imitation feather yarn fabric, depending on the need. That is, those skilled in the art can choose to prepare either a single-sided or double-sided imitation feather yarn fabric, and thus select the corresponding finishing process.

[0021] As a preferred embodiment of the present invention, when the imitation feather yarn fabric is a double-sided imitation feather yarn fabric, the finishing process includes sequentially performing a napping treatment and a combing treatment. That is, when the imitation feather yarn fabric is a single-sided imitation feather yarn fabric, the napping treatment is not required.

[0022] The napping process can pull fibers out of the yarn to form fluff. As a preferred technical solution of the present invention, the conditions for the napping process include: the napping roller speed is 600-800 rpm, the fabric speed is 15-20 m / min, the number of napping times is 2-3 times, and the needle cloth insertion depth is 2-3 mm.

[0023] Combing can straighten messy fluff. As a preferred technical solution of the present invention, the conditions for combing include: the combing roller speed is 400-600 rpm, the fabric speed is 12-18 m / min, and the number of combing times is 1-2.

[0024] The shaking treatment causes the fluff to form a fluffy, entangled structure. As a preferred technical solution of the present invention, in step S7, the conditions of the shaking treatment include: shaking temperature of 80-100℃, shaking time of 20-40min, shaking speed of 30-50rpm, and cooling method of natural cooling to below 40℃.

[0025] As a preferred technical solution of the present invention, in step S8, the blow-drying process includes: a first blow-drying process, a second blow-drying process, and a third blow-drying process performed sequentially. The conditions for the first blow-drying process include: air temperature of 100-110℃, relative humidity of 30%-40%, air pressure of 0.4-0.5MPa, blow-drying angle of 30-45°, and fabric speed of 8-12m / min. The conditions for the second blow-drying process include: air temperature of 85-95℃, relative humidity of 15%-20%, air pressure of 0.3-0.4MPa, blow-drying angle of 20-30°, and fabric speed of 8-12m / min. The conditions for the third blow-drying process include: air temperature of 70-80℃, relative humidity of less than 5%, air pressure of 0.2-0.3MPa, blow-drying angle of 10-20°, and fabric speed of 8-12m / min.

[0026] The relative humidity mentioned above can be controlled by mixing in the corresponding steam and blowing it in hot air.

[0027] This invention has discovered that using a blown fiber process and controlling the blown fiber process under the aforementioned conditions can result in fabrics with better softness and lint resistance. It is speculated that this is because the first blown fiber process causes the polyester fibers to absorb moisture and swell, lowering their glass transition temperature. Under the action of an airflow at a medium angle of 0.4-0.5 MPa, the roots of the pile tightly adhering to the base fabric are blown up. The subsequent second blown fiber process keeps the fibers in a plastic state, orienting the pile. The final third blown fiber process dehydrates and sets the fibers, fixing the shape of the pile, thereby achieving better pile formation.

[0028] In addition, when the imitation feather yarn fabric is a double-sided imitation feather yarn fabric, the blown-down process in this invention can be performed on one side or both sides, and those skilled in the art can choose according to their needs.

[0029] As a preferred technical solution of the present invention, in step S9, the conditions for the three-stage setting treatment include: the treatment liquid consists of 3-8 g / L of amino-modified organosilicon softener, 20-30 g / L of anti-pilling agent, and the remainder is water; the rolling mill pressure is 3-4 bar, the liquid content is 60%-70%; the overfeed is 5%-8%; the machine speed is 15-20 m / min; setting at 120-130℃ for 20-30 seconds, then setting at 160-175℃ for 20-30 seconds, and finally setting at 135-140℃ for 20-30 seconds.

[0030] The above-mentioned amino-modified silicone softener uses Hongqi amino silicone oil, and the anti-pilling agent uses JYD700HG.

[0031] In this invention, controlling the three-stage setting under the above conditions can reduce the amount of fabric shedding and increase the softness of the fabric. It is speculated that this is because the first stage of low temperature allows the treatment liquid to fully spread and penetrate, the anti-pilling agent migrates to the root of the pile, and the softener is evenly distributed on the surface. Then, the second stage of high temperature can promote the cross-linking reaction of the anti-pilling agent at the root, forming a high-density reinforcement layer at the root of the pile, firmly anchoring the pile to the base fabric. Finally, the third stage of medium temperature treatment allows the softener to form a low-crosslinking lubricating film at the tip of the pile, giving a silky touch while avoiding the high temperature from damaging the already formed fluffy structure.

[0032] The above three-stage setting process can be carried out according to conventional process steps in this field. That is, the blown fabric is fed into the padding and impregnation steps using a fabric feeder and tension adjusting rollers. The padding pressure is controlled at 3-4 bar, and the liquid content of the fabric after padding is 60%-70%. Then, it enters the overfeed roller and the overfeed is adjusted to 5%-8%. Finally, the speed is controlled at 15-20 m / min and it enters ovens 1-6 for setting. Ovens 1-6 are of the same length, and the temperatures of ovens 1-6 are 120-130℃, 120-130℃, 165-175℃, 160-175℃, 130-140℃, and 130-140℃ respectively. The setting time is 60-90 seconds.

[0033] Secondly, the present invention provides a feather-like yarn fabric, which is prepared by the above-described method for preparing feather-like yarn fabric.

[0034] Compared with the prior art, the present invention has at least the following beneficial effects: 1. In the preparation of feather-like yarn and down fabrics, the interweaving of specific raw materials gives the fabric a biomimetic feel and warmth.

[0035] 2. In this invention, the combination of sorting, shaking, and blow-drying can improve the warmth retention rate and reduce the amount of shedding.

[0036] 3. In this invention, by combining various shaping processes, internal stress can be eliminated and the fabric shape can be stabilized without damaging the already formed fluffy entangled structure, resulting in a softer fabric. Detailed Implementation
