Disclosed is a curly fiber having a fiber centroid and comprising a first region having a first centroid and a second region wherein the first region comprises an ethylene/alpha olefin interpolymer composition in an amount of at least 75 weight percent based on total weight of the first region and wherein the ethylene/alpha olefin interpolymer composition is characterized by a low temperature peak and a high temperature peak on an elution profile via improved comonomer composition distribution (ICCD) procedure, and a full width at half maximum of the high temperature peak is less than 6.0° C. and the second region is a material comprising a polymer which is different from the ethylene/alpha-olefin interpolymer of the first region and wherein the regions are arranged such that at least one of the first centroid and the second centroid is not the same as the fiber centroid.

Crimped multi-component fibers

A process comprising forming fibers having at least a first region and a second region wherein the first region comprises an ethylene/alpha olefin interpolymer composition characterized by: density in the range of 0.930 to 0.965 g/cm; melt index (I2) in the range of from 10 to 60 g/10 minutes; molecular weight distribution in the range of from 1.5 to 2.6; tan delta at 1 radian/second of at least 45; a low temperature peak and a high temperature peak on an elution profile via improved comonomer composition distribution (ICCD) procedure; and full width at half maximum of the high temperature peak is less than 6.0° C. and stretching the fibers to an elongation of at least 20% thereby increasing curl of the fiber. The process may further include forming a non-woven from the fibers and the stretching of the fibers may occur before or after forming of the non-woven.

Method of manufacture of curly fibers

Embodiments of the present disclosure are directed to multilayer silo bags that may include a tube comprising at least two layers, a first open end, a second open end, and a first region and a second region disposed between the first and second end. One or more of the at least three layers may comprise an ethylene/alpha-olefin interpolymer having a density of 0.90 g/cc to 0.965 g/cc and an Iof 0.1 to 6.0 g/10 minutes, a low density ethylene-based polymer having a density of 0.917 g/cc to 0.935 g/cc and an Iof 0.1 to 2.0 g/10 minutes, or combinations thereof. The first region may have a thickness of at least 10% greater than a thickness of the second region. The first region may have a surface area that is at least 50% of an overall surface area of the multilayer silo bag.

Silo bags with non-uniform thickness and methods of producing

The present disclosure is directed to a dosing cap (). In an embodiment, the dosing cap () includes (A) a collar member (). The collar member () has an annular skirt () depending from a base ()(B). An inner surface of the skirt has a securing member for securing the collar member to a neck () of a container (). The base (B) has (i) a top surface () and a bottom surface (), (ii) a valve seat () is present on the top surface of the base. The valve seat has a center channel (), and a radial channel (), the channels extend through the base. The dosing cap includes (C) a plug member (). The plug member is composed of a polymeric material. The plug member has the following components in inter-connected relationship: a head (), a body (), a leg (), an ankle (), and a flexible foot (). The leg extends through the center channel, such that the head opposes the valve seat on the top surface of the base and the foot opposes the bottom surface of the base. The dosing cap further includes (D) a cap member () having an annular sidewall () extending from a dispensing element (). An inner surface of the annular sidewall has an attachment member adjustably attached to a reciprocal attachment member on an outer surface of skirt. The dosing cap includes (E) a metering chamber (). The metering chamber is formed by an enclosed volume between the cap member and the base. The dispensing element (F) permits flow of a fluid from the metering chamber.

Dosing cap with adjustable volume

The present disclosure provides a dosing cap. In an embodiment, the dosing cap includes (A) a collar member having an annular skirt depending from a base. An inner surface of the annular skirt has a securing member for securing the collar member to a neck of a container. The base includes (i) at least one opening with a one-way valve permitting fluid flow in a first direction, and (ii) an air channel with a one-way valve permitting fluid flow in a second direction. The dosing cap includes (B) a cap member having an annular sidewall extending from a dispensing element. An inner surface of the annular sidewall has an attachment member adjustably attached to a reciprocal attachment member on an outer surface of the first sidewall. The dosing cap includes (C) a metering chamber formed by an enclosed volume between the cap member and the base. The dosing cap includes (D) the dispensing element permitting flow of a fluid from the metering chamber.
