Description

Technical Field

[0001] This invention belongs to the field of quilt fabric technology, specifically, it relates to a lint-resistant and anti-static all-season quilt fabric and its preparation method. Background Technology

[0002] As an important category of modern home textiles, all-season quilts have gained widespread popularity in recent years due to their ability to meet the needs of different seasons—spring, summer, autumn, and winter—through the free combination of quilt filling thickness or the two-way temperature regulation function of the fabric itself. However, with consumers' continuous improvement in their requirements for sleep comfort and health and hygiene, existing all-season quilt fabrics have revealed many shortcomings in terms of functionality. Among them, the problems of attracting lint and dust and static electricity accumulation are the most prominent, and have become key technical bottlenecks restricting product upgrades.

[0003] In daily life, quilt fabrics easily attract various tiny particles such as shed skin flakes, hair, indoor dust, and pet hair. This is especially true in the dry autumn and winter seasons, where friction between fibers exacerbates static electricity, significantly increasing the fabric's ability to attract lightweight particles. Traditional all-season quilt fabrics are often made by blending synthetic fibers like polyester and nylon with natural fibers like cotton and viscose. While this balances strength and moisture absorption to some extent, these fibers have high surface resistivity, easily generating static charges during friction that are difficult to dissipate quickly. Once these charges accumulate, the fabric not only becomes sticky and uncomfortable against the skin, affecting sleep quality, but also creates a strong static attraction to dust and hair, causing significant problems for daily cleaning and maintenance. Even though some products attempt to alleviate these issues with simple anti-static finishing, conventional anti-static agents are easily washed away in large quantities, making it difficult to guarantee the durability of the anti-static effect. Therefore, it is urgent to solve these problems to meet the higher technical requirements of the quilt fabric technology field. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a lint-resistant and anti-static all-season quilt fabric and its preparation method.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] A lint-resistant and anti-static all-season comforter fabric, comprising the following raw materials in parts by weight: 45-60 parts cotton fiber, 25-40 parts lyocell fiber, and 3-8 parts organic conductive fiber.

[0007] As a further technical solution, the organic conductive fiber comprises the following raw materials in parts by weight: 70-80 parts polyamide 6 chips, 6-12 parts antistatic agent, 0.3-0.8 parts antioxidant and 0.2-0.5 parts lubricant.

[0008] As a further technical solution, the antioxidant is a hindered phenolic antioxidant.

[0009] As a further technical solution, the lubricant is a stearic acid-based lubricant.

[0010] As a further technical solution, the organic conductive fiber is prepared through the following steps:

[0011] A1. Add polyamide 6 chips, antistatic agent, antioxidant and lubricant into a mixer and mix to obtain a mixture;

[0012] A2. The mixture is fed into a twin-screw extruder for melt blending and then extruded and granulated to obtain antistatic masterbatch;

[0013] A3. The antistatic masterbatch is fed into a melt spinning machine. After the raw material is melted, it is extruded through a spinneret and cooled to obtain nascent fibers.

[0014] A4. Finally, the nascent fibers are stretched by hot rollers, then heat-set and wound to obtain organic conductive fibers.

[0015] As a further technical solution, the temperature of the mixer is 80-90℃, the rotation speed is 800-1000r / min, and the mixing time is 20-30min.

[0016] As a further technical solution, the heat setting temperature is 130-150℃ and the time is 0.5-1s.

[0017] As a further technical solution, the antistatic agent is prepared through the following steps:

[0018] B1. In a three-necked round-bottom flask (equipped with a magnetic stirrer, a constant-pressure dropping funnel, and a reflux condenser), add 3-pyridinemethanol and acetonitrile, start stirring, and then place the flask in an ice-water bath (0-5℃) to cool. Using a constant-pressure dropping funnel, slowly add chloroacetaldehyde dropwise into the flask. After the addition is complete, remove the ice-water bath, heat in an oil bath to 75-80℃, and reflux for 8-10 hours. Once the reaction is complete, perform post-processing to obtain the intermediate product.

[0019] B2. In a round-bottom flask (equipped with a magnetic stirrer and a reflux condenser), add the intermediate product, p-phenylenediamine and acetonitrile, start stirring, then add glacial acetic acid and anhydrous sodium sulfate (as a dehydrating agent) to the flask, heat in an oil bath to 80-85℃, reflux for 4-6 hours, after the reaction is complete, post-process to obtain the diol product.

[0020] B3. In a four-necked flask (equipped with a stirrer, thermometer, reflux condenser, and vacuum interface), terephthalic acid, isophthalic acid, ethylene glycol, and tetrabutyl titanate (catalyst) are added sequentially. Stirring is started, and the oil bath temperature is raised to 175-180℃. The vacuum pump is turned on (vacuum degree -0.02MPa), and the reaction is continued for 3-4 hours to generate a prepolymer. The vacuum is turned off, and the temperature is lowered to 140-150℃. Then, polyethylene glycol (PEG1000) and the diol product are added. After stirring evenly, nitrogen gas is introduced three times, the vacuum is turned on, and the oil bath temperature is gradually raised to 220-230℃. The reaction is carried out for 40-50 minutes. After the reaction is completed, the product is post-processed to obtain an antistatic agent.

[0021] As a further technical solution, the ratio of 3-pyridinemethanol to chloroacetaldehyde in step B1 is 10.9g:9.1-9.4g.

[0022] As a further technical solution, the ratio of intermediate product to p-phenylenediamine in step B2 is 32.8-33.4g:10.8g.

[0023] As a further technical solution, the ratio of the amounts of terephthalic acid, isophthalic acid, ethylene glycol, polyethylene glycol and diol products in step B3 is 92g:8g:48g:90g:12g.

[0024] In the preparation process of this invention, in order to ensure the antistatic agent is obtained, in step B2, the molar ratio of the intermediate product and p-phenylenediamine must be strictly controlled to be close to 2:1, and the intermediate product must be in excess to ensure complete reaction.

[0025] The reaction equations for steps B1 and B2 are as follows:

[0026]

[0027] The antistatic agent prepared by this invention belongs to the polyether ester antistatic agent category. The polyethylene glycol segment is a hydrophilic soft segment. In the fabric's usage environment, it can absorb trace amounts of moisture from the air, forming an extremely thin water molecule film on or inside the fiber surface. This significantly reduces the surface resistivity of the fiber, improving the fabric's antistatic performance. Furthermore, since the antistatic agent of this invention is a polymer, it is not washed away by water, unlike small-molecule antistatic agents, and has good durability. In addition, the quaternary ammonium salt group introduced into the antistatic agent not only provides cations to further improve the matrix's antistatic performance, but the pyridine quaternary ammonium salt, carrying a positive charge, can adsorb and destroy the bacterial cell membrane structure, leading to intracellular leakage and exerting a broad-spectrum antibacterial effect. Finally, the antistatic agent molecule also contains a Schiff base (imine group), which can also inhibit the activity of key bacterial metabolic enzymes, thereby achieving antibacterial action. This synergistic effect with the quaternary ammonium salt avoids the potential for drug resistance arising from a single antibacterial mechanism.

[0028] This invention also provides a method for preparing a lint-resistant and anti-static all-season quilt fabric, comprising the following steps:

[0029] C1. Cotton fibers, lyocell fibers and organic conductive fibers are mixed in multiple bins and then opened and cleaned. Subsequently, carding, drawing (using three-stage drawing), roving and spinning processes are carried out in sequence to obtain yarn.

[0030] C2. The yarn is wound, warped, sized (using a starch / PVA mixed sizing agent), and threaded onto heddles and reeds. Then, it is woven using an air-jet loom. Once the weaving is complete, the greige fabric is obtained.

[0031] C3. The raw fabric is singed (to remove excess fuzz from the surface), desized with amylase, boiled with alkali to remove impurities, and bleached with hydrogen peroxide. After dyeing, a four-season quilt fabric that is lint-resistant and anti-static is obtained.

[0032] As a further technical solution, the draft ratio in the spinning process is 25-40 times.

[0033] As a further technical solution, the woven fabric structure is a five-end three-fly satin weave.

[0034] As a further technical solution, the weaving speed is 600-800 r / min, and the machine tension is 2000-3000 N.

[0035] As a further technical solution, the desizing temperature of the amylase desizing is 60-70℃, and the desizing time is 40-60min.

[0036] As a further technical solution, the concentration of caustic soda in the alkaline boiling process is 8-12 g / L, the boiling temperature is 95-100℃, and the boiling time is 50-70 min.

[0037] The beneficial effects of this invention are:

[0038] 1. The antistatic agent prepared in this invention is added into the fiber internally rather than as a simple surface coating. The polyethylene glycol segments absorb moisture to form a conductive water film, and the quaternary ammonium salt cations provide ion conduction channels in low humidity environments. The two complement each other, enabling the fabric to quickly dissipate static charge in all humidity ranges throughout the four seasons, thereby eliminating the adsorption of dust, dander, and pet hair by electrostatic attraction from the source and achieving long-lasting anti-hair adhesion.

[0039] 2. The antistatic agent is a high molecular weight polyether ester copolymer, which has significantly better wash resistance than conventional small molecule antistatic agents;

[0040] 3. The antistatic agent molecule contains both pyridine quaternary ammonium salt and Schiff base. The two mechanisms complement and synergistically enhance the antibacterial properties of the fabric.

[0041] In summary, the fabric produced by this invention has excellent lint-resistant, antistatic, and antibacterial properties, and has important application value in the field of quilt fabric technology. Detailed Implementation
