Pulp，指的是纤维材料的浆液，它的主要组成物往往是木浆和纸浆，用以制造一系列的抽象物品，如纸张。它以很细小的纤维粒子组成，有时这些纤维粒子需要添加一些其他的添加剂，例如防止腐烂的酸甚至是某种油脂。PaperPulpisthemainrawmaterialusedinpapermaking。Itismadefromvariousplants，treesandrecycledmaterialssuchasoldnewspapers。Thepulpisthenprocessedandtreatedtoproduceathickmixtureoffiberssuspendedinwater。Thisisthenpassedthroughpowerfulrollersinordertopressthewateroutandformlargesheetsthatarethencutintostandardsizepaper。Inrecentyears，paperpulphasbeenincreasinglyreplacedwithrecyclableandeco-friendlymaterials。Theseincludematerialssuchasgrassandstraw，whicharemadeintouncomplicatedpaperpulp。Inaddition，manymanufacturersareusingreusablematerialssuchascloth，cotton，andotherfibrousproductsinsteadofpaperpulp，inordertoreducetheamountofwasteproducedbytheindustry。
