Embodiment 1

[0036] The properties of the thermally bonded spunlaced nonwoven fabrics are reported in Table 1 below. All performance measurements were made on 8 (or 10?) samples and averaged.

[0037] Example 2

[0038] This example was prepared in the same manner as Example 1 except using about 7.9% binder fiber and processing a blend of bicomponent and monocomponent fibers per card. The amounts of polyester base fiber and wood pulp are provided in Table 1.

Embodiment 2

[0040] This example was prepared in the same manner as Example 1, except that about 13.1% binder fiber was used, wherein the bicomponent fiber contained 26% PET / 74% PET copolymer with a cut length of 1.7 dtex 38 mm supplied by ADVANSA, Germany. things. Each card processes a blend of bicomponent and monocomponent fibers. The amounts of polyester base fiber and wood pulp are provided in Table 1.

Embodiment 3

[0042] nature

[0043] The presence of binder fibers in the cleaning fabric provides increased MD grab modulus and reduced XD necking. All strength data provided are for dry samples. Lubricated samples showed similar results.

Description

technical field [0001] The present invention relates to nonwoven fabrics for cleaning cylinders of machines, such as cylinders of printing machines. Background technique [0002] Cleaning the cylinders of printing presses with nonwoven fabrics is known in the art. Nonwoven cleaning fabrics with reduced air content, and the use of such fabrics to clean cylinders of printing presses, are described in US Patent No. 5,974,976 to Gasparrni et al. Wet-laid webs for cleaning the cylinders of printing presses are described in US Patent Application Publication No. 2002 / 0187307 to Tanaka et al. A wet-laid sheet containing about 5-50% by weight of binder fibers is hydroentangled and tightly twisted, followed by heating to melt the tightly twisted binder fibers. Examples of wet laid sheets include sheets comprising at least 50% pulp. [0003] In an effort to reduce costs and reduce the environmental impact of printed materials, recycled paper was used as the raw material for printin...
