With the rapid development of the domestic home textile market, there are higher and multiple requirements for the functionality of home textile fabrics. No single natural or chemical fiber can meet these requirements. It is the future development trend to try to achieve these functions through the combination of multiple fibers and multiple chemical finishing methods.
1. Warmth retention
Although the warmth retention is closely related to the thickness of the fabric, users do not like quilts and other bedding products to be too heavy. Therefore, both warmth and lightness have become the basic requirements for current bedding products. According to Home Textile Investment Network, a common method to achieve this requirement is to make the polyester fiber into a porous hollow shape inside, so that the fiber contains a large amount of stagnant air, and the outside is made into a spiral curl shape to maintain fluffiness, so it can ensure a light texture. It plays a good thermal insulation role under the premise. In addition, special ceramic powders containing chromium oxide, magnesium oxide, and zirconium oxide are added to the spinning solution of polyester and other synthetic fibers, especially nano-scale fine ceramic powders, which can absorb visible light such as sunlight and convert it into heat energy, so it has Excellent thermal insulation and heat storage properties. In addition, far-infrared ceramic powder, adhesive and cross-linking agent are 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 between the yarns. This kind of finishing agent has health functions such as antibacterial, deodorizing, and promoting blood circulation.
2. Antibacterial and deodorizing properties
Since towels are often dipped in water and generally placed in a relatively humid environment, microorganisms will multiply, which may cause the towels to emit odor and cause itching in the user. Therefore, the requirements for towels are relatively high, and it is best if they are treated with antibacterial and deodorant chemicals. The general approach is to use a finishing agent with bactericidal effect to make it have certain antibacterial properties. In recent years, Japan has done a lot of research on natural antibacterial finishing agents. For example, it uses aromatic oil extracts with bactericidal effects such as aloe vera and mugwort leaves, and coats them in porous organic microcapsules or porous ceramic powders. On the fabric, it is cross-linked and fixed with resin, and the bactericide is slowly released through mechanical effects such as friction and accumulation to achieve the purpose of durable antibacterial finishing. This type of natural antibacterial agent has certain health care functions. However, due to the current limited technology for fixing antibacterial agents, the washing resistance of the antibacterial agent is not good enough. The antibacterial performance decreases every time it is washed, and usually disappears completely after dozens of times.
3. Anti-fouling and decontamination properties
Home textiles such as sofas and sofas are required to be as hard as possible to be stained by stains, and once stained, they must be easy to wash and remove. According to the Home Textile Investment Network, the commonly used technology is to change the surface properties of fibers and greatly reduce the surface tension of the fabric, making it difficult for oil and other stains to penetrate into the interior of the fabric. Slight stains can be removed by wiping with a damp cloth. Heavier stains are also easy to clean. Anti-fouling finishing can not only prevent oil pollution, but also has waterproof and moisture-permeable properties. It is a relatively practical and effective advanced chemical finishing method.
4. Waterproof
Home textiles such as curtains and sofas require fabrics with good waterproof properties. Waterproof fabrics make use of the surface tension properties of water and coat the fabric with a layer of PTFE and the chemical combination of polytetrafluoroethylene (PTFE), the “king of corrosion-resistant fibers”. The chemical coating with the same composition but different physical structure enhances the surface tension of the fabric, making it impossible for water droplets to penetrate the pores on the surface tissue of the fabric, thereby achieving a waterproof effect.
5. Moisture permeability
Due to their own usage characteristics, quilt cover household textiles require fabrics with moisture permeability. The moisture permeability of the fabric can be achieved in the fabric structure. For example, a double-layer tissue structure is used. The inner layer is made of hydrophobic fibers and the outer layer is made of hydrophilic fibers. In this way, sweat can be transferred from the skin to the skin by capillary action. On the inner layer of fibers, because the binding force between the outer layer of hydrophilic fibers and water molecules is stronger than that of the inner layer of hydrophobic fibers, the water molecules are transferred from the inner layer of the fabric to the outer layer again, and then emitted.
6. Antistatic
Home textiles are basically made of chemical fiber fabrics. Whenever water is easy to evaporate and the environment is relatively dry, static electricity becomes a problem. Static electricity generally makes household textiles prone to fluffing and pilling, easily contaminated with dust and dirt, and causing a sensation of electric shock when close to the skin. Good antistatic fabrics are made of natural fibers, but pure natural fiber fabrics are often expensive and difficult to satisfy consumers of different levels of home textile products. Moreover, even natural fiber fabrics will suffer from lack of water molecules in very dry environments. And produce static electricity. The antistatic finishing method for home textile fabrics mainly uses antistatic agents with hygroscopic effects to coat the surface of the fabric with a chemical film that can absorb water molecules, so that a continuous conductive water film is formed on the surface of the fabric, and the electrostatic conduction escapes. scattered. This method can make the fabric antistatic without affecting its softness and comfort.
For home textile products with relatively fixed styles and designs,�The development of fabric technology may be one of the strong driving forces for the development of the industry.
