no. 1 approach

[0144] The nonwoven fabric is manufactured with 4.4 dtex trilobal fibers and 6.7 dtex round fibers (preferably made of polypropylene or polyester, for example). Both fibers have the same coverage distance when observed under the microscope. For 4.4 dtex trilobal fibers, the coverage distance (distance of solid material fibers) is almost equal to that of 6.7 dtex linear mass density circular cross-section fibers.

[0145] For each fiber, a 5-layer nonwoven was constructed using the following parameters:

[0146] ·The first needle board: 75 needles / cm from top to bottom 2 , puncture depth 11.5mm, 4500 needles / m at the entrance, 7000 needles / m at the exit, needle type 15x18x36 3,5R222G3037.

[0147] ·Second needle board: 100 needles / cm from bottom to top 2 , puncture depth 11mm, the whole board 7000 needles / meter, needle type 15x18x36 3,5R222G3037.

[0148] ·Third needle board: 100 needles / cm from top to bottom 2 , the puncture depth is 8mm, the whole board is 7000 needles / m...

no. 2 approach

[0165] In other embodiments, samples fabricated as described in Embodiment 1 were combined using three different backing methods:

[0166] 1. Pre-coated backing

[0167] 2. Full bath resin backing

[0168] Precoated Backing Embodiments

[0169] A suspension of latex and chalk in water was applied by a kiss roll system at a weight of 300 g / m 2 The circular needle felt and the weight is 260g / m 2 and 210g / m 2 The hairiest side of the trefoil needle felt. Fibers can be made from polypropylene. The suspension density was set at 1200 g / l. The carpet then passes through a first oven at 140°C followed by a second oven at 120°C. After that, cut off the edges of the carpet and cut the remaining 4 meter wide carpet into two parts with a width of about 2 meters.

[0170] The following carpets were backed and final roll weights observed (Table 2 - performed on 4m wide carpet)):

Embodiment approach

[0177] Apply 245g / m using the same settings as the pre-coated backing 2 The wet latex weight is applied to the carpet sample. The latex is pressed through the nonwoven fabric using soft silk to ensure complete impregnation. The carpet width after trimming the edges is exactly 4 meters.

[0178] The following carpets were backed and observed for final roll weight (Table 3):

[0179]

[0180] table 3

[0181] Raised carpets with trelobal fibers showed sufficient stiffness and coverage, especially based on trelobal 210g / m 2 The hardness and coverage of the raised carpet. And the trefoil rug has a pure white color and richness of the rug.

Abstract

An event or exhibition carpet is described having a needle felt structure which can be low in weight but having good abrasion resistance. In accordance with embodiments of the present invention the event or exhibition carpet comprises at least a needle punched facing layer as a top layer made of staple fibers, wherein the staple fibers comprise at least 50% by weight of solid multilobal fibers, and at least a partial binding. A process for making this event or exhibition carpet is described comprising the steps of: conveying a fibrous card web to a crosslapping machine and crosslapping the card web into a batt of material, wherein the multilobal nonwoven crosslapper travelling distance is less than 20% and larger than 10% bigger than the final width of the needle punched facing layer.

Description

[0001] The present invention relates to nonwoven event or exhibition carpet and methods of making and installing the same. Background technique [0002] Event or exhibition carpets are a separate class of carpets that include textile floor coverings, usually needle-punched floor coverings, such as floor coverings with a needle-felt structure, used as floor coverings at trade fairs, conventions, and other events. Temporary (e.g. single use or limited duration) covering. Typically, nonwoven fabrics based on circular cross-section fibers are used. A carpet for covering floors of conferences, conventions, fairs, festival performances, exhibition halls, event halls, etc. has a pile portion composed of a needle-punched nonwoven fabric forming a surface layer. A primary backing cloth may be applied underneath the aforementioned pile portion. Latex can be used to impregnate the back surface of the carpet. [0003] The useful life of exhibition or event rugs is usually limited by th...
