Embodiment 1

[0066] Embodiment 1 (comparison)

[0067] exist figure 1 Two 920 denier 8 dpf colorless nylon 6,6 BCF yarns were processed on a Volkman twister as described in to form a 5.75 tpi (twist per inch) 2-ply cabled yarn. The twisting speed was about 7000 rpm (turns per minute) and the winding speed was about 50 m / min. The cabled yarn has no color. The cabled yarn was heat set on a Superba and converted on a 1 / 8 ga tufting machine to a cut pile carpet of 22 / 32 inch pile height, 35 oz / square yard carpet and dyed on a continuous dye line to obtain Medium pie crust color. This example was carried out by dyeing the carpet using a continuous dyeing machine using state-of-the-art carpet manufacturing methods.

Embodiment 2

[0068] Embodiment 2 (the present invention)

[0069] exist figure 2 Two 920 denier 8 dpf colorless nylon 6,6 BCF yarns were processed on a Volkman twister as described in to form a 5.75 tpi (twist per inch) 2-ply cabled yarn. A wicking dye applicator is inserted between the take-up roll and the winder. Acid dye mixture (Blue 4R 5.0 g / l and Orange 3G 2.0 g / l in deionized water, pH 9.47) was applied to the cabled yarn using a 0.5 inch wide by 1 inch thick cotton wick (wet wick, Perperell MA) on-line. The twisting speed was about 7000 rpm (turns per minute) and the winding speed was about 50 m / min. The cabled yarns were heat set on a Superba at 265°F and tufted on a 1 / 8 ga tufting machine to a cut pile carpet of 22 / 32 inch pile height, 35 oz / square yard of carpet. The tufted carpet has a medium shade of green (L 51.26, a-9.71, b +1.45, Minolta).

Embodiment 3

[0070] Embodiment 3 (the present invention)

[0071] exist figure 2 Two 920 denier 8 dpf colorless nylon 6,6 BCF yarns were processed on a Volkman twister as described in to form a 5.75 tpi (twist per inch) 2-ply cabled yarn. A wicking dye applicator is inserted between the take-up roll and the winder. Acid dye mixture (Orange 3G 5.712 g / l, Red 2B 2.52 g / l in deionized water, pH 6) was applied to cabled yarn using a 0.5 inch wide by 1 inch thick cotton wick (wet wick, Perperell MA) on-line. The twisting speed was about 7000 rpm (turns per minute) and the winding speed was about 50 m / min. The cabled yarns were heat set on a Superba at 265°F and tufted on a 1 / 8 ga tufting machine to a cut pile carpet of 22 / 32 inch pile height, 35 oz / square yard of carpet. This tufted rug is bright brown in color (L 39.17, a 10.48, b 18.14, Minolta). There were many dark, medium and light spots randomly distributed on the blanket, which produced an interesting salt and pepper toner mi...

Abstract

Disclosed are processes for applying dyes, stain blocker and anti-soil compositions on BCF yarns during cable or air twisting processes, or heat setting processes, prior to weaving, knitting or tufting. Further discloses are process for applying dyes, stain blocker and anti-soil compositions on BCF yarns prior to heat setting. The processes forego the need to dye and otherwise treat carpets and other textiles made from the BCF yarn using current methods. Also disclosed are systems, BCF yarns, and carpets made from the BCF yarn treated by the disclosed process.

Description

field of invention [0001] The present invention relates to the processing method of bulk continuous filament (bulk continuous filament, BCF) blanket and related textile fabric. Method of Applying Dyes and Topical Treatment Compositions to BCF Yarns During the Process. The method does not require dyeing and additional treatment of carpets and other textiles made from the BCF yarns using current methods. Thus, low inventory overhead is achieved and costly and environmentally unfriendly dyeing and low pH chemical treatments are eliminated. Also disclosed herein are systems for applying dyes and performance enhancing formulations to BCF yarns and stain / stain-resistant yarns and carpets with improved stain and stain resistance properties made from BCF yarns of the disclosed methods . technical background [0002] Rugs and other fabrics made from synthetic yarns are currently colored using two generally accepted methods. The first method involves converting the colorless white...
