Abstract

Methods and systems are provided for a process to generate a nonwoven textile. In one example, the nonwoven textile may have layered, zonal properties resulting from entangling of two or more types of staple fibers through a merging region between the layers of staple fibers while maintaining distinct zones, each zone comprising a type of staple fiber. Furthermore, the process may include embedding a filament layer into the nonwoven textile via a continuous assembly line.

First claim

The invention claimed is:

1. A method of generating a nonwoven textile, comprising:
generating a web including a first staple fiber, a second staple fiber, and a continuous filament at least partially aligned with one another, wherein the first staple fiber included in the web is a different type of fiber than the second staple fiber included in the web, wherein the continuous filament is further aligned within a width of the web that includes the first staple fiber and excludes the second staple fiber; and
pleating the web along a first axis while moving the pleated web along a second axis, offset from the first axis and substantially perpendicular to the first axis.

2. The method of claim 1 , wherein generating the web includes carding the first and second staple fibers along the first axis via a carding machine, wherein pleating the web includes repeatedly pleating via a cross-lapping machine, and wherein the web that is repeatedly pleated via the cross-lapping machine includes the first staple fiber and the second staple fiber.

3. The method of claim 2 , further comprising felting the pleated web along the second axis via a felting machine, and continuously feeding the pleated web to the felting machine.

4. The method of claim 3 , wherein the moving includes continuously moving the pleated web from the cross-lapping machine, away from the carding machine, and towards the felting machine, the cross-lapping machine including a pleating head having a first static roller and a second mobile roller, the second mobile roller continuously moving towards and away from the first roller with a frequency, wherein a degree of pleating of the pleated web is based on the frequency.

5. The method of claim 1 , wherein the continuous filament is inserted into the web via a threading machine.

6. The method of claim 1 , wherein the second staple fiber and the first staple fiber that is the different type of fiber than the second staple fiber are included in the web prior to the web being pleated.

7. The method of claim 6 , wherein the first staple fiber and the second staple fiber comprise different physical properties, wherein the web is a first web, and wherein the pleated web is a second web that includes the first staple fiber and the second staple fiber, wherein the second staple fiber of the second web touches a surface of a conveyor belt that moves the second web along the second axis, and wherein the first staple fiber of the second web is not in contact with the surface of the conveyor belt.

8. The method of claim 7 , wherein the first staple fiber is included in a first portion of a width of the first web that includes additional fibers that are a same type of fiber as the first staple fiber, wherein the second staple fiber is included in a second portion of the width of the first web that includes additional fibers that are a same type of fiber as the second staple fiber, wherein the first portion of the width of the first web is adjacent to the second portion of the width of the first web, and wherein the width of the first web extends in a direction that is different than a width of the second web.

9. The method of claim 8 , wherein the at least partial alignment of the first staple fiber and the second staple fiber to each other in the first web is alignment in the direction the width of the first web extends.

10. A method of generating a nonwoven textile, comprising:
generating a web including a first staple fiber, a second staple fiber, and a continuous filament at least partially aligned with one another, wherein the first staple fiber included in the web is a different type of fiber than the second staple fiber included in the web, wherein the web further includes a first fiber zone including the first staple fiber and excluding the second staple fiber and a second fiber zone including the second staple fiber and excluding the first staple fiber, wherein the continuous filament is included in one of the first fiber zone or the second fiber zone; and
pleating the web along a first axis while moving the pleated web along a second axis, offset from the first axis and substantially perpendicular to the first axis.
