PLA bi-component staples are a leading and distinctive product of eSUNFiber, with mature production technology and stable product quality. The product is a bi-component skin-core structure composite fiber made of 100% polylactic acid, where the sheath component is made of low melting point polylactic acid with good softness, and the core component is made of high melting point polylactic acid with high strength.
(1).Non-woven Fabric Applications, such as sanitary materials, packaging materials, medical supplies
Due to its softness, low-temperature processability, non-toxicity, non-irritation, and lightweight, bi-component PLA fiber is ideal for manufacturing sanitary pads, diapers, and other hygiene products.
PLA bi-component staple is further processed into through-air, hot-rolling, needle punch, spun lace, and non-woven fabrics. It is applied to fast-moving consumer goods, packaging materials, and medical supplies.
(2).Thermal bonding applications
PLA Bi-component Staple is an ideal thermally bondable fiber, mainly used for the thermal bonding process of non-woven fabrics. This is a form of “point bonding” rather than “area bonding,” thus the product possesses characteristics such as bulkiness, softness, high strength, oil absorption, blood absorption, and other factors.
Using PLA bi-component fiber for thermal bonding has the advantage of achieving adhesion without the need for adhesives. This not only avoids the need to handle excess components, making it environmentally friendly and in line with the concept of sustainable development, but it also allows for a wide range of fabric properties and aesthetics.
When bi-component PLA fiber is mixed with natural fibers, man-made fibers, pulp, etc., and processed through dry or wet non-woven fabric processes, it significantly enhances the strength of the non-woven fabric. It also imparts dryness, breathability, antibacterial, and deodorizing effects to natural fiber products, complementing their advantages and significantly improving the performance of non-woven fabrics. This composite material is also widely used in disposable sanitary materials (including diapers, sanitary pads, underpads, healthcare mattresses, etc.) for top layers, bottom layers, and wrapping materials).
PLA bi-component staple can also be applied to filter materials, gardening household materials, insulation materials, adsorption materials, packaging materials, rigid fiberboards, automotive wall materials, and padding, etc.
(3).Fillers
Utilizing the difference in properties of the two components, the shrinkage difference is generated after stretching and heat treatment, causing the fibers to produce permanent three-dimensional natural curls. Therefore, it can be widely used as fillers, such as flakes, stuffed toy fillings, mattresses, etc.. Its natural drying, antibacterial, and deodorizing properties have wide application advantages in baby products, elderly products, and pet products.
