Problems solved by technology

While its strength properties are improved by entanglement of the fibers within the batt, the process is slow and the needles themselves wear out quickly as they damage the fibers, so the process is inherently only suitable for heavy substrates tangle

Embodiment Construction

[0023] The support fabric for spunlace of the present invention can be applied to such as image 3 In the hydroentanglement system shown, the system is described in detail in column 2, line 25 to column 4, line 3 of U.S. Patent 6,163,943, and as the figure 1 . When the fabric of the present invention is used as image 3 For the system shown, the fabric should be formed as a continuous belt and the wire mesh 12 replaced by this belt.

[0024] The support fabric for hydroentanglement of the present invention is preferably woven from monofilaments in the warp and weft directions. As known to those of ordinary skill in the art, when the fabric is woven by endless weaving or modified endless weaving, the warp monofilaments are located in the cross direction (CD) of the fabric, and when the fabric is flat woven, the warp monofilaments The filaments are located in the machine direction (MD) of the fabric. In contrast, the weft monofilaments are in the machine direction (MD) of the...

Abstract

A fabric incorporating flattened filaments for use as a support fabric in producing a nonwoven product by a hydroentangling process, and a hydroentangling method employing such a fabric.

Description

technical field [0001] The present invention relates to the production of nonwoven fabrics, and more particularly, the present invention relates to the production of nonwoven fabrics by using hydroentanglement. Background technique [0002] Nonwoven fabrics are used in a variety of applications that take advantage of the engineering properties of the fabrics. This type of fabric differs from conventional woven or knitted fabrics in that the fibers or filaments of the fabric are incorporated into a coherent web without the use of a conventional textile weaving process. The entanglement of the fabric fiber units provides the desired integrity to the fabric, and the selected entanglement process allows the fabric to be patterned to achieve the desired aesthetic. [0003] Nonwoven fabrics generally consist of fibers that are locked into place by fiber-fiber interaction to form a firmly bonded structure, usually without the need for adhesives or fusing of the filaments.
