摘要： A multi-ply laminate formed from at least two laminated nonwoven webs. One of the nonwoven webs is formed from filaments meltspun at a spinning speed insufficient to return the crystallinity of the constituent polymer to the crystallinity before conversion to a molten state for meltspinning, which makes these filaments prone to shrinkage when heated. Other nonwoven web(s) in the laminate are formed from filaments characterized by a substantially recrystallized polymer. The laminate is heated to a temperature sufficient to cause contraction of filaments in the non-woven web of deficient crystallinity. The shrinkage reduces the surface area of the non-crystallized web relative to the surface area of the crystallized web(s), which have substantial dimensional stability. This results in blousing manifested by raised areas that increases the loft and improves other properties of the multi-ply laminate.

摘要： Multicomponent filaments for manufacturing a hydrophilic nonwoven web in which each filament has a sheath and a core enclosed within the sheath that includes a concentration of an additive, such as a surfactant. Additive removed from an external surface of the sheath is replaced by additive migrating outwardly from the sheath. Additive migrating outwardly from the core into the sheath, which initially either includes a smaller additive concentration than the core or lacks additive, serves to replenish additive transferred from the sheath to the external surface.

摘要： Apparatus and methods for folding a nonwoven web without mechanical contact against a folding surface. A first portion of the nonwoven web is secured to a collector by vacuum and a positive pressure differential is applied to a second portion of the moving nonwoven web. An unbalanced lifting force applied by the positive pressure differential causes the first portion to fold along a longitudinal fold line extending in a machine direction and to assume an overlapping relationship with the second portion. The vacuum assists in the folding process and maintains the overlapping relationship until the nonbonded nonwoven web is consolidated. One or more elastic strands or bands may be captured in the space defined between the overlapped first and second portions.

摘要： A counter-rotating sewer cleaning nozzle to provide improved efficient cleaning of interior surfaces of sewer lines. The counter-rotating sewer cleaning nozzle is comprised of a hose connector on one end and nose cone on the opposite end and retaining between them counter-rotating sleeves fitting over a cylindrical conduit. Each of the sleeves has spray jets in communication with a passageway connecting the cylindrical conduit to the hose connector for receiving water at high pressure from a high-pressure hose or pipe. The jets in the counter-rotating sleeves are at an oblique angle to the radius of the sleeves and the cylindrical conduit. The spray jets are angled in opposite directions in the forward and rear rotatable sleeves to provide counter rotation. When water is forced at high pressure through the sewer cleaning nozzle, the nozzle jets rotate the respective counter-rotating sleeves in opposite directions to provide efficient cleaning of crevices and irregular surfaces on interior surfaces of sewer lines.
摘要翻译：一个反向旋转的下水道清洁喷嘴，可以对污水管线内表面进行有效的清洁。反向旋转下水道清洁喷嘴由一端的软管接头和相对端的鼻锥组成，并保持在它们之间的相反旋转的套筒配合在圆柱形导管上。每个套筒都具有与将圆柱形管道连接到软管连接器的通道连通的喷射喷嘴，用于从高压软管或管道接收高压水。反向旋转套筒中的喷嘴与套筒和圆柱形导管的半径呈倾斜角。喷嘴在前后可旋转套筒中以相反方向成角度，以提供反向旋转。当水通过下水道清洁喷嘴被迫在高压下时，喷嘴喷射使相应的反向旋转套筒沿相反的方向旋转，以提供对下水道内表面上的缝隙和不规则表面的有效清洁。
