- the cup is removed and the stained sample is allowed to sit undisturbed for 24 hours.
- the stained sample is rinsed thoroughly under cold tap water, excess water is removed by centrifugation, and the sample is dried in air.
- the sample was visually inspected and rated for staining according to the .FD&C Red No. 40 Stain Scale described in AATCC Method 175-2003. Stain resistance is measured using a 1-10 scale, An undetectable test staining is accorded a value of 10.
- WAQE SHAMPOO TEST Caipeting wash durability was tested by the shampoo-Wash Durability Test, using Duponol WAQE as detergent, as referenced and described in U.S. Pat, Nos, 5,853,814 and 5,948,480. Each sample tested according to this method was visually inspected and- rated for staining according to the FD&C Red No. 40 Stain Scale described in AATCC Method 175-2003.
- a 997 denier Antique White color solution dyed BCF (997 -E 2779 by Invista) made from cationic dyeabie nylon 66 polymer was first converted into 6,0 twist per inch, cable twisted yarns, and subsequently heatset on Superba using different process settings. The cable twisted and heatset yarns were converted into 45 oz caipets for stain and floor performance tests
- This item was heatset on Superba using the state of art process. Twelve ends of cable twisted yarns were first processed through the texturing unit, heated with 99° C atmospheric saturated steam for about 5 seconds in the pre-bulker and set in tunnel with 130° C pressurized saturated steam for about 60 seconds. The processed yam was converted into a 45 oz yd., 19/32 inch pile height cut pile carpet on a 1/10 ga. machine. The tufted carpet was coated with latex t secure tufts using the state of ait latexing process. The finished carpet had excellent tip definition.
- This item was test for stain and texture retention. It scored a 6 (1 to 10 rating, 10 has no stain) for 24 hour stain resistance, and a 5 for WAQE Shampoo stain resistance, it failed the stain performance requirement for premium carpets. The texture retention was excellent This item was rated 3.8 (1 to 5 scale) for carpet durability after five thousand cycles in a Vetterman drum.
- This item was test for stain and texture retention, it scored an 8 (1 to 10 rating, 10 has no stain) for 24 hours stain resistance and an 8 for WAQE Shampoo stain resistance. It performed significantly better than the carpet described in Example 1. The texture retention was excellent. It also scored 3.8 (1 to 5 scale) for carpet durability after 5 thousand cycle test in a Vetterman drum- Example 3 (current invention)
- This item was test for stain and texture retention. It scored an 8 (1 to 10 rating, 10 has no stain) for 24 hours slain resistance and a 7 for WAQE Shampoo stain resistance. It performed significantly better than the carpet described in Example 1. The texture retention was excellent. It also scored 3.8 (1 to 5 scale) for carpet durability after 5 thousand cycle test in a Vetterman arum.
- This item was tested for stain and texture retention. It scored an 8 (1 to 10 rating, .10 has no stain) for 24 hours stain resistance and a 9 for WAQE Shampoo stain resistance. It performed significantly better than Example 1. The texture retention was acceptable, but not. good as previous examples. It scored 3.2 (1 to 5 scale) for carpet durability after 5 thousand cycle test in a Vetterman drum. Although it passed the end use tests, it cannot be sold as a premium commercial product due to poor ti definition.
