摘要： The invention is aimed to provide a core-sheath type composite filament, in which a functional component is hardly lost due to volatilization during the melt forming; bleeding of the internally added functional component is effectively inhibited; the internally added functional component does not adversely affect spinning properties, stretching properties, strength and dimensional stability; the use of the functional component can be greatly reduced, leading to a reduction of production cost; superior functionalities of deodorizing properties and antimicrobial properties can be exhibited to a maximum extent; even when contacting with water, the functionalities can be kept over a long time; and the composite filament is highly safe to a human body. The invention is also aimed to provide a process for the production of the core-sheath type composite filament as well as a heat fused article obtained from the composite filament. The core-sheath type composite filament of the invention is composed of a core component X and a sheath component Y, wherein the core component X is formed from a first polyolefin resin (H), and the sheath component Y is formed from a second polyolefin resin (L) compounded with at least one functional component (A) selected from the group consisting of a catechin, a saponin, a tea-leaf powder, a tea-leaf extract, and tannin (tannic acid), and a ceramics component (C).
摘要翻译：本发明的目的在于提供一种芯鞘型复合长丝，其中功能性成分在熔融成形期间由于挥发而几乎不会损失; 内部添加的功能成分的渗透被有效地抑制; 内部添加的功能组分不会对纺丝性能，拉伸性能，强度和尺寸稳定性产生不利影响; 功能部件的使用可以大大降低，导致生产成本降低; 除臭性能和抗菌性能优异的功能最大程度可以展现出来; 即使与水接触，功能也可以长时间保持; 复合长丝对人体的安全性高。本发明的目的还在于提供一种用于生产芯鞘型复合长丝的方法以及由复合长丝获得的热熔制品。本发明的芯鞘型复合长丝由芯成分X和鞘成分Y构成，其中，芯成分X由第一聚烯烃树脂（H）形成，鞘成分Y由第二聚烯烃与选自由儿茶素，皂角苷，茶叶粉末，茶叶提取物和单宁酸（鞣酸）组成的组中的至少一种功能性成分（A）和陶瓷成分（ C）。
