Description

Technical Field

[0001] This invention belongs to the field of textile technology, specifically relating to anti-pilling cotton / polyester, wool, and spandex elastic pique fabrics and their preparation methods. Background Technology

[0002] Stretch pique knit fabric offers excellent wearing comfort and a feeling of freedom, along with good moisture absorption and breathability. However, due to its relatively loose knit structure, after repeated friction, the rigidity of the polyester fibers can cause them to entangle with the cotton fibers, making them difficult to shed and resulting in pilling. This affects its actual performance to some extent. Good anti-pilling properties are especially crucial for knitted T-shirts.

[0003] By blending cotton / polyester, wool, and spandex, the resulting fabric has a smoother, more delicate feel, and its elasticity, resilience, and shape retention are significantly improved. Fabrics containing short fibers are more prone to pilling, affecting their appearance. Improving the pilling resistance of this blended fabric, combined with the three-dimensional feel of a pique knit structure, will undoubtedly provide users with a superior wearing experience.

[0004] Chinese patent CN109097900A discloses a method for preparing a lightweight four-way stretch high-grade cotton-ammonia fabric. The fabric includes terry yarn, center yarn, and ground yarn, and includes the following steps: A: weaving the fabric rough; B: shaking the surface of the fabric rough; C: dyeing; D: dehydration; E: drying; F: re-setting. The fabric woven by this method has good elasticity and excellent elastic recovery. The new weaving method effectively improves the weft skew, maintaining excellent touch and anti-pilling properties. However, this method does not include a suitable singeing process during finishing, resulting in irregular long fibers on the fabric surface and poor luster.

[0005] Chinese patent CN115287890A discloses a pilling-resistant and lint-resistant knitted fabric and its pretreatment process. The fabric is primarily polyester, and pretreatment is performed before pilling, specifically during the degreasing and washing stage before dyeing. Using a self-made synergist and alkaline complexing agent, and following a specific process, the resulting pilling-resistant and lint-resistant knitted fabric shows significant improvement in pilling and lint resistance, and its style is slightly better than traditional methods, with positive feedback in actual wear. However, this process does not involve high-temperature pre-forming of the raw material, resulting in severe edge curling during dyeing and uneven dyeing between the edges and center of the fabric.

[0006] Chinese patent CN102561040A discloses a new anti-pilling process for polyester-cotton fabrics under special standards. The process involves the following steps: fabric turning → initial singeing → bleaching → secondary singeing → setting → mercerizing → dyeing (dispersion / reduction) → finishing with a compound solution of wrinkle-free resin and anti-pilling agent → baking → stretching → pre-shrinking → inspection → finished product. The resulting product achieves an anti-pilling performance of export standard 3-4. However, because spandex and wool have relatively low melting points, they cannot withstand intense singeing and will burn. If the fabric described in this invention is used in this process, the fabric will be burned and unusable. Therefore, the process described in this invention is completely unsuitable for the fabric processing required by this invention.

[0007] Because wool and spandex have low melting points, this property dictates that the singeing process during fabric finishing cannot be too intense; otherwise, the wool and spandex fibers will be burned. Therefore, high-intensity singeing cannot solve the pilling problem. Thus, finding a production process to improve the pilling resistance of cotton / polyester, wool, and spandex blended fabrics would not only give the fabric a smooth and clean appearance but also reduce damage to its strength, especially important for high-yarn-count fabrics. This also aligns with people's pursuit of aesthetics, comfort, and ease of care, making it of great significance. Summary of the Invention

[0008] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an anti-pilling cotton / polyester, wool, and spandex elastic pique fabric, which solves the problem of pilling in cotton / chemical fiber blended knitted T-shirts. It has excellent anti-pilling function, a smooth and clean appearance, good shape retention, comfortable wear, and good moisture absorption and breathability, meeting people's pursuit of beauty, comfort, and easy care.

[0009] Another objective of this invention is to provide a method for preparing anti-pilling cotton / polyester, wool, and spandex elastic pique fabric, which is simple, scientific, and reasonable.

[0010] The technical solution adopted in this invention is as follows:

[0011] The method for preparing the anti-pilling cotton / polyester, wool, and spandex elastic pique fabric involves weaving and finishing cotton / polyester, wool, and spandex as raw materials; wherein the finishing process includes the following steps:

[0012] Setting → First light singeing → First etching → Second wet cloth singeing → Second etching → Third wet cloth singeing → Stretching → Pre-shrinking → Steaming.

[0013] The raw materials, by weight percentage, consist of: 40-60 wt.% cotton / polyester, 35-50 wt.% wool and 5-15 wt.% spandex; wherein, in the cotton / polyester mixture, the weight percentage of cotton is 45-75 wt.% and the weight percentage of polyester is 25-55 wt.%.

[0014] The weaving is carried out using a circular knitting machine, with a weaving specification of 36"40G~36"44G; the 100-round yarn length of cotton / polyester is 22.5~24.5cm, the 100-round yarn length of wool is 15~17.5cm, and the 100-round yarn length of spandex is 7.5~8.5cm.

[0015] The setting process is dry setting of the greige fabric, with a temperature of 200-208℃, a machine speed of 20-28m / min, and an upper / lower air volume of 85-95% / 80-90% in the drying room. The process conditions are as follows: the woven fabric is fed into the drying room at a flat width, widened by a needle plate, and then laid flat.

[0016] The first light singeing method involves cutting and burning in alternating directions, with a flame intensity of 4-6 mbar and a machine speed of 100-110 m / min. The process conditions are as follows: the incoming fabric is stacked in a J-shape and enters the brushing box, singes through the singeing nozzle, enters the extinguishing box, and is laid flat.

[0017] The second wet singeing process involves through-burning, alternating between positive and negative burns, with a flame intensity of 8–10 mbar and a machine speed of 100–110 m / min. The fabric moisture content before singeing is 80–85 wt.%, and the process conditions are as follows: the incoming fabric is stacked in a J-shape and enters the brushing box, singes through the singeing nozzle, enters the fire extinguishing box, and is laid flat. The second etching process involves a bath ratio of 1:(12–15), a polishing enzyme dosage of 0.1–0.2 wt.%, a pH value of 7.0–7.5, a temperature of 65–70℃, an etching time of 20–30 min, and the polishing enzyme is D300, purchased from Suzhou Liansheng Chemical Co., Ltd.

[0018] The third wet fabric singeing process involves direct burning, alternating between positive and negative burns, with a flame intensity of 8-10 mbar and a machine speed of 100-110 m / min. The fabric moisture content before singeing is 40-50 wt.%, and the process conditions are as follows: the incoming fabric is stacked in a J-shape and enters the brushing box, singes through the singeing nozzle, enters the fire extinguishing box, and is then laid flat.

[0019] The stretching speed is 20-30 m / min, the temperature of the drying chamber is 120-140℃, the upper / lower air volume of the drying chamber is 65-75% / 60-70% respectively, and the concentration of anti-slip agent in the material tank is 5-20 g / L. The process involves two dips and two nips. The anti-slip agent is L26, which was purchased from Giovanni Busset (Shanghai) Chemical Industry and Trade Co., Ltd. The process conditions are as follows: the woven fabric is fed into the material tank at a flat width, and then widened by the needle plate before entering the drying chamber and finally laid flat.

[0020] The pre-shrinking speed is 20-25 m / min, overfeed 10-15%, rubber blanket temperature is 90-100℃, and felt blanket temperature is 100-105℃. The process conditions are: the incoming fabric is fed in at a flat width, passes through the widening needle plate into the pre-shrinking section of the rubber blanket, passes through the felt blanket, and is laid flat and dropped. The steaming speed is 15-20 m / min, the felt blanket drying temperature is 80-90℃, and the steam spray rate is 110-150 kg / h. The process conditions are: the incoming fabric is fed in at a flat width into the mesh belt, passes through the felt blanket for drying, and is laid flat and dropped.

[0021] The anti-pilling cotton / polyester, wool, and spandex elastic pique fabric is prepared by the above-mentioned preparation method of anti-pilling cotton / polyester, wool, and spandex elastic pique fabric.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] (1) The anti-pilling cotton / polyester, wool, and spandex elastic pique fabric solves the problem of pilling in cotton / chemical fiber blended knitted T-shirts. It has excellent anti-pilling function, a smooth and clean appearance, good shape retention, comfortable to wear, and good moisture absorption and breathability, which meets people's pursuit of beauty, comfort and easy care.

[0024] (2) The preparation method of the anti-pilling cotton / polyester, wool, spandex elastic pique fabric adopts a combination of dry and wet singeing to minimize the fuzz on the fabric surface while ensuring that the strength of the fabric is not affected. Under dry conditions, the process conditions of low flame intensity and high speed are used. In the instantaneous contact, the fibers are burned off due to the heat. The fabric itself is relatively dense and heats up slowly. It leaves the flame before reaching the ignition point, thus achieving the purpose of burning off the fuzz on the fabric surface without damaging the fabric. Under wet conditions, the brushing device is used to brush up the shorter fibers attached to the surface of the fabric. Under the conditions of low speed and high flame intensity, the brushed fibers will be burned off, while the fabric is still in a wet state and the fabric will not be damaged.

[0025] (3) The preparation method of the anti-pilling cotton / polyester, wool, spandex elastic pique fabric uses a higher loom size and a shorter design 100-round thread length, resulting in a fabric with good resilience and greater comfort when worn. The removal effect is enhanced by combining dry and wet singeing with tackification. Enzyme treatment eliminates smaller fibers on the fiber surface, making the fabric surface smoother and improving anti-pilling performance. In the stretching process, the anti-pilling properties of the fabric are further improved by using an anti-slip agent that increases the friction between fibers. Detailed Implementation
