2、36-A5 POLYETHYLENE BACKED, 340 g/m NOT TO BE USED FOR NEW DESIGN 1. SCOPE The materials defined by this specification are bulked continuous filament (BCF) nylon, cut pile carpets, tufted into a synthetic primary foundation. It is then coated with a polyethylene back coating. 2. APPLICATION This mate
3、rial was released originally for carpets used for full floor application as part of the Carpet Construction Strategy. 3. REQUIREMENTS In addition to the requirements listed herein, the end-item carpet assembly (molded or otherwise fabricated) shall meet all requirements of the WSS-M8P16-A performanc
4、e specification for full floor applications and the appropriate requirements in the Sound and Heat SDS. This carpet meets the Resistance to Abrasion requirement of 2,000 cycles per paragraph 3.13 of WSS-M8P16-A, therefore, throw-in mats must be standard equipment or a heel pad must completely cover
5、the areas most vulnerable to driver wear. 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). 3.2 SAMPLE SELECTION All evaluations shall be conducted on test specimens t
6、aken from finished roll goods prior to any subsequent operations, such as reheating or molding. 3.3 APPEARANCE (FLTM BI 109-01) The color, pattern, and finish shall match the approved Design Center master sample, or shall be as specified on the engineering drawing. 3.4 COMPOSITION (ASTM D 276) Pile

8、 (ASTM D 1577) 135 - 165 tex t0 (nylon, crimped textured, bulked continuous filament, 2.3 2.9 tex). 3.6.2 Pile Count (ASTM D 5793) Rows 30/100 mm min. Stitches 35/100 mm min. Rows and stitches per 100 mm shall be based on an average count on a 254 mm length of carpet and shall not exceed +/- 10% of
9、the set value. 3.6.3 Foundation Materials Primary (Tufting Foundation) 100% Polyester or 75%/25% PET/PA6 3.6.4 Backcoating The polyethylene back coat shall form a continuous and uniform coating over the back of the carpet so that all pile fibers are covered. The back coat shall be thoroughly melted
10、and shall maintain its ability to lock in the pile fibers in the end-item, molded carpet assembly. The back coat shall thoroughly saturate the base of the pile fiber bundles to ensure adequate tuft lock. Penetration of the back coat through to the face shall be controlled to provide the required res
11、istance to abrasion and fiber loss, but the back coat shall not be visible on the face of the pile fiber. 3.6.5 Needle Gauge 3.2 mm 3.6.6 Pile Height 5.6 mm (ASTM D 5823) Pile height shall not exceed +/- 0.8 mm of the set value. 3.7 WEIGHT, g/m2min (ASTM D 5848) Pile Yarn 339 Primary Foundation Material 100 Backcoating 330 3.8 FLAMMABILITY (ISO 3795/SAE J369) Burn Rate, max 100 mm/minute
