Description
技术领域 technical field
本发明涉及一种适合家用内部装饰材料的无纺布，本发明还涉及一种适合家用内部装饰材料的无纺布的生产方法，属于无纺织技术领域。 The invention relates to a nonwoven fabric suitable for household interior decoration materials, and also relates to a production method of the nonwoven fabric suitable for household interior decoration materials, which belongs to the field of nonwoven technology.
背景技术 Background technique
无纺布（英文名：Non Woven Fabric 或者 Nonwoven cloth）又称不织布，是由定向的或随机的纤维而构成，是新一代环保材料，具有防潮、透气、柔韧、质轻、不助燃、容易分解、无毒无刺激性、色彩丰富、价格低廉、可循环再用等特点。如多采用聚丙烯（pp材质）粒料为原料，经高温熔融、喷丝、铺纲、热压卷取连续一步法生产而成。因具有布的外观和某些性能而称其为布。无纺布根据成分，有涤纶、丙纶、锦纶、氨纶、腈纶等；不同的成分会有截然不同的无纺布风格。而纺粘布，通常指的是涤纶纺粘、丙纶纺粘；而这两种布的风格非常接近，通过高温测试才能判别出。 Non-woven fabric (English name: Non Woven Fabric or Nonwoven cloth), also known as non-woven fabric, is composed of directional or random fibers. , non-toxic, non-irritating, rich in color, low in price, recyclable and so on. For example, polypropylene (pp material) pellets are mostly used as raw materials, which are produced by continuous one-step process of high-temperature melting, spinning, laying, and hot-pressing coiling. It is called cloth because of its appearance and certain properties. According to the composition of non-woven fabrics, there are polyester, polypropylene, nylon, spandex, acrylic, etc.; different compositions will have completely different styles of non-woven fabrics. The spunbond fabric usually refers to polyester spunbond and polypropylene spunbond; and the styles of these two fabrics are very similar, and can only be identified through high temperature testing.
无纺布由包括化学纤维和植物纤维等在以水或空气作为悬浮介质的条件下在湿法或干法抄纸机上制成，虽为布而不经纺织故称其为无纺布。无纺布是新一代环保材料，具有强力好、透气防水、环保、柔韧、无毒无味，且价格便宜等优点。它是新一代环保材料，具有拒水、透气、柔韧、不助燃、无毒无刺激性、色彩丰富等特点。该材料若置于室外经自然分解，其最长寿命只有90天，置于室内在8年内分解，燃烧时无毒、无味、且无任何遗留物质，从而不污染环境，故环保由此而来。 Non-woven fabrics are made of chemical fibers and plant fibers on wet or dry paper machines under the condition of water or air as the suspension medium. Although they are cloth without weaving, they are called non-woven fabrics. Non-woven fabric is a new generation of environmentally friendly materials, which has the advantages of good strength, breathability and waterproof, environmental protection, flexibility, non-toxic and tasteless, and cheap price. It is a new generation of environmentally friendly materials, with the characteristics of water repellency, breathability, flexibility, non-combustibility, non-toxic and non-irritating, and rich colors. If the material is naturally decomposed outdoors, its longest lifespan is only 90 days, and it decomposes within 8 years when placed indoors. It is non-toxic, tasteless, and has no remaining substances when burned, so it does not pollute the environment, so environmental protection comes from this .
随着人们时尚概念意识的不断提高，对并不限于前面例举的寝装用品、医疗卫生用品、妇幼卫生用品、一次性生活用品乃至车辆内饰用品如汽车顶棚和地毯等等的质量和形式要求日益严苛，因此期望目前广泛使用的无纺布除了具备抗菌杀菌的长处外，还具有颜色能够保持持久鲜艳，且造型效果好，除臭净化的效果。 With the continuous improvement of people's awareness of fashion concepts, the quality and form of bedding products, medical and sanitary products, maternal and child hygiene products, disposable household products and even vehicle interior products such as car roofs and carpets are not limited to those listed above. The requirements are becoming more and more stringent, so it is expected that the widely used non-woven fabrics not only have the advantages of antibacterial and sterilizing, but also have the effect of maintaining bright colors, good styling effects, and deodorizing and purifying effects.
