2、3-B3 HEAVY LAYER SUBSTRATE, PIECE DYED 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 latex coating and then laminated to a heavy lay
3、er substrate. This carpet is piece dyed. 2. APPLICATION This material was released originally for carpet used for Accessory Mat applications as part of the Carpet Construction Strategy. 3. REQUIREMENTS In addition to the requirements listed herein, the end-item carpet assembly (molded or otherwise f
4、abricated) shall meet all requirements of the WSS-M15P44-A performance specification and the Sound and Heat Control (INSUL) SDS for accessory mat applications. 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements
5、For Production Materials (WSS-M99P1111-A). 3.2 SAMPLE SELECTION All evaluations shall be conducted on test specimens taken 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 approve

Stitches 51.0/100 mm min.
8、Rows and stitches per 100 mm shall be based on an average count on a 254 mm length of carpet. 3.6.3 Foundation Materials Primary (Tufting Foundation) SBPET 3.6.4 Precoat The latex shall form a continuous and uniform coating over the back of the carpet so that all pile fibers are covered. The latex s
9、hall be thoroughly cured and shall maintain its ability to lock in the pile fibers in the end-item, molded carpet assembly. The latex shall thoroughly saturate the base of the pile fiber bundles to ensure adequate tuft lock. Penetration of the latex through to the face shall be controlled to provide
10、 the required resistance to abrasion and fiber loss, but the latex shall not be visible on the face of the pile fiber. 3.6.5 Needle Gauge 1.98 mm 3.6.6 Pile Height, max. 6.2 mm (ASTM D 5823) 3.7 WEIGHT, g/m2, min (ASTM D 5848) Pile Yarn 515 Primary Foundation Material 100 Latex 335 Heavy Layer Substrate, min. 2000 3.8 FLAMMABILITY (ISO 3795/SAE J369) Burn Rate, max 100 mm/minute
