Polylactic acid filament
Overview
Product Description
1. Product Overview
In the innovation process of textile materials, polylactic acid filament stands out as a highly promising new – type fiber material. It is constructed from multiple long single filaments through precise stretching, twisting, or texturing processes. Each process is carefully regulated to ensure the excellent quality of the fiber assembly. Among them, the internal structure of polylactic acid multifilament is exquisite, with dozens of single filaments neatly arranged in one strand. This unique structure endows it with diverse application methods. It can be directly applied to the weaving of high – end textile products. With its delicate texture and good performance, it adds a unique charm to the fabric. It can also be used as a raw material to spin into differentiated polylactic acid yarns, meeting the urgent needs of the modern textile industry for diversified and functional products. Polylactic acid monofilament, with its unique physical and chemical properties, shows irreplaceable important value in many fields with extremely high requirements for material performance, such as medical suturing, fishing, and tea bags.
2. Product Characteristics
- Environmental Biodegradability：The biodegradable property of polylactic acid filament makes it a star material in the environmental protection field. In the natural environment, through the action of microorganisms, it can gradually decompose into water and carbon dioxide. The whole process does not produce any harmful substances that are difficult to degrade, greatly reducing the environmental burden and providing strong support for the sustainable development of the textile industry.
- Safety and Health Assurance：In terms of its impact on the human body, polylactic acid filament is completely non – toxic, residue – free, and has excellent biocompatibility with human tissues. This means that it can not only safely contact the skin without causing allergic reactions and other adverse reactions but can also be used in products that come into direct contact with the human body in the medical field, such as medical sutures, ensuring that there is no potential threat to human health.
- Natural Bacteriostatic Function：Polylactic acid filament exhibits a natural weak – acid property, which endows it with powerful antibacterial and anti – mite abilities. At the same time, it can effectively inhibit the growth of mold and extend the freshness – keeping period of products. When applied in home textile products, it can create a healthy and clean living environment for users.
- Comfortable Breathability Experience：Polylactic acid filament performs outstandingly in terms of wearing comfort. Its excellent breathability and moisture – permeability can quickly dissipate the sweat excreted by the human body, keeping the skin dry at all times. Moreover, it has the characteristics of quick – wash and quick – dry, greatly shortening the drying time after washing and providing great convenience for users.
- Outstanding Physical Properties：The physical properties of polylactic acid filament are very excellent. It has a low thermal conductivity coefficient and good heat – preservation performance, which can keep the human body warm in cold weather. At the same time, its high – resilience characteristic makes the clothing made from it not easy to deform during the wearing process, always maintaining a good pattern. Its texture is light, smooth, and fluffy, which not only makes it comfortable to wear but also adds a unique texture to the fabric. In addition, it can effectively resist the invasion of ultraviolet rays, protecting the human skin from harm.
- Flame – Retardant and Safe：In terms of fire safety, polylactic acid filament is a reliable guardian. It has the characteristic of extinguishing immediately when leaving the fire source. Once the fire source is removed, the flame will quickly go out, effectively preventing the spread of fire. Moreover, during the combustion process, it produces very little smoke and does not release toxic substances, buying precious time for personnel evacuation and rescue work and ensuring the safety of life and property.
3. Product Specifications
- Polylactic acid monofilament：As an important member of the polylactic acid filament family, polylactic acid monofilament plays a key role in specific fields with its unique properties. In the field of medical suturing, its high strength and flexibility can ensure the tight suture of wounds, and its good biocompatibility ensures the smooth healing of wounds. In the fishing field, its water – resistance and high strength make it an ideal material for making fishing lines and other fishing gear. In the production of tea bags, the filter made of polylactic acid monofilament can effectively filter tea leaves and ensure stability and safety when soaked in hot water.
- FDY fully – drawn yarn：The FDY fully – drawn yarn series provides a rich selection of specifications, such as 30D/36F, 75D/36F, 100D/36F, etc. The finer 30D/36F specification is suitable for making high – end silk – textured fabrics, lightweight underwear, etc. Its delicate texture can bring an ultimate wearing experience. The 75D/36F specification achieves a good balance between strength and softness and is often used for making daily shirts, dresses, and other clothing. The 100D/36F specification is relatively thicker and has higher strength, suitable for making home textile products that require a certain degree of wear resistance, such as curtains, sofa covers, etc.
- DTY texturing filament：DTY texturing filament, also known as “DTY drawn – textured yarn”, by using the thermoplasticity of synthetic fibers and adopting a unique process of first twisting and then untwisting, it forms a spring – like shape. Although it seems to be twisted, it is actually false – twisted, so it is also commonly known as elastic yarn. This series of products is divided into two types: high – elastic and low – elastic. High – elastic products have excellent elasticity and are especially suitable for making sportswear, such as yoga clothes, running gear, etc., which can provide sufficient stretching space for the human body during exercise while maintaining the fit of the clothing. Low – elastic products, while ensuring a certain degree of elasticity, pay more attention to stability and comfort. They are often used in daily clothing, such as casual pants, knitted sweaters, etc., and in the home textile field for bedding, carpets, etc., bringing a comfortable user experience.
FAQ
- How is polylactic acid filament formed? Polylactic acid filament is formed by a fiber assembly made from multiple long single filaments through processes such as stretching, twisting, or texturing. During this series of processing, the properties of the single filaments are optimized and combined to form polylactic acid filaments with specific properties.
- What are the characteristics and uses of polylactic acid multifilament? A polylactic acid multifilament contains dozens of single filaments in one strand. This structure gives it good strength and flexibility. It can be used directly in some textile products with high requirements for fiber performance, or it can be spun into differentiated polylactic acid yarns to further expand its applications in the textile field, meeting the diverse needs of different products for texture, function, and other aspects.
