In addition to the inherent quality requirements, fabrics used in the early stages of household textiles only have certain requirements for shrinkage and color fastness. With the rapid development of the domestic home textile market, there is a higher demand for the functional type of home textile fabrics. The requirements for household textiles are also harsh: for towels, adults and children must use it every day, so the water absorption, antibacterial and deodorant requirements of the fabric are high; for bedding, in pursuit of warmth. It is not too heavy; for curtains, it not only has to play a role in decoration indoors, but also has high requirements for windproof and waterproof; for sofa cloth, in addition to aesthetics and feel, it requires In addition, the fabric has good anti-stick and decontamination properties is also an important measure. These performance requirements are very demanding from a textile technology point of view, and even many indicators are mutually incompatible. Any single natural or chemical fiber can't meet these requirements, and can only achieve these functions through the combination of multiple fibers and multi-channel chemical finishing.
1. Warmth: Although the warmth is closely related to the thickness of the fabric, but the user does not like the bedding such as quilt is too thick, so it is necessary to keep warm and light to become the basic requirements of the current bedding. The most common way to achieve this requirement is to make the inside of the polyester fiber porous and hollow, so that the fiber contains a large amount of non-circulating air, and the outer part is spirally curled to maintain the bulkiness, so that it can be used under the premise of ensuring light texture. Good insulation.
In addition, a special ceramic powder containing chromium oxide, magnesium oxide, zirconium oxide, or the like, especially a nano-scale fine ceramic powder, which absorbs visible light such as sunlight and converts it into heat energy, is added to a synthetic fiber spinning solution such as polyester. Excellent insulation and heat storage performance. The far-infrared ceramic powder, the binder and the cross-linking agent are also formulated into a finishing agent, the fabric is coated, and then dried and baked to make the nano-ceramic powder adhere to the surface of the fabric and the yarn. The finishing agent has the health care functions of inhibiting bacteria, deodorizing, promoting blood circulation and the like.
2, antibacterial, deodorant: Because towels are often used in drowning, generally placed in a relatively humid environment, microorganisms will multiply, may cause the towel to emit odor and cause the user's itching. Therefore, the requirements for towels are relatively high, and it is best to undergo antibacterial and deodorant chemical treatment. The general approach is to use a bactericidal finishing agent to impart a certain antibacterial property. In recent years, Japan has made a lot of research on the research of natural antibacterial finishing agents, such as the use of aromatic oil extracts such as aloe vera and argyi, which are bactericidal, and coated in porous organic microcapsules or porous ceramic powders. On the fabric, the resin is cross-linked and fixed, and the fungicide is slowly released by mechanical action such as friction and backlog to achieve the purpose of durable antibacterial finishing. This kind of natural antibacterial agent has certain health care functions. However, due to the limited technology of immobilizing antibacterial agents, the anti-washing property of antibacterial agents is not good enough, and the antibacterial properties are reduced once per washing, and generally disappear after dozens of times.
3, anti-fouling, decontamination: sofa cloth home textiles are not as easy to be stained by stains, once it is contaminated, it should be easy to wash and remove. At present, the commonly used technology is to change the surface properties of the fiber, greatly improving the surface tension of the fabric, so that oil stains and other stains are difficult to penetrate into the interior of the fabric, and slight stains can be removed by wiping with a damp cloth, and heavy stains are also easy to remove. Cleaning. The anti-fouling finishing can not only prevent the pollution of oil pollution, but also has the performance of waterproof and moisture permeability, and is a relatively practical and effective advanced chemical finishing means.
4, waterproof: curtains, sofa cloth home textiles require fabrics with good water resistance, waterproof fabric is the use of water surface tension characteristics, coated with a layer of PTFE on the fabric (with the "king of corrosion-resistant fiber" Tetrafluoroethylene PTFE has the same chemical composition but different physical structure. The chemical coating that enhances the surface tension of the fabric makes the water droplets unable to penetrate the pores on the surface of the fabric to achieve a waterproof effect.
5, moisture permeability: quilt-type home textiles due to their own use characteristics, the fabric needs to have moisture permeability. The moisture permeability of the fabric can be achieved on the fabric structure. For example, the double-layer structure is used, the inner layer of the body is made of hydrophobic fiber, and the outer layer is made of hydrophilic fiber, so that the sweat can be transferred from the skin by capillary action. On the inner layer of fibers, the binding force between the outer hydrophilic fibers and the water molecules is stronger than the inner layer hydrophobic fibers, and the water molecules are again transferred from the inner layer of the fabric to the outer layer, and finally emitted.
6, anti-static: household textiles are basically made of chemical fiber fabric, whenever the water is easy to volatilize, the environment is relatively dry, static electricity becomes a problem. Static electricity generally makes home textiles easy to pilling, easy to contaminate dust and dirt, and close to the skin with electric shock. The best antistatic fabrics are woven from natural fibers, but pure natural fiber fabrics are often expensive, difficult to meet the needs of different levels of home textiles consumers, and even natural fiber fabrics, in a very dry environment, due to lack of water Molecules generate static electricity. The antistatic finishing route of home textile fabrics mainly adopts antistatic agent with hygroscopic effect, and coats the surface of the fabric with a chemical film which can adsorb water molecules, so that a continuous conductive water film is formed on the surface of the fabric, and the static electricity is transferred. Scattered. This method allows the fabric to have antistatic properties without compromising its softness and comfort.
