Embodiment I

[0100] Example I - Monochrome Fabric

[0101] a) Extrude olefin pellets having a melt flow index of 8-22 and intimately mix with the blend using the above preferred mixture of PETG and maleic anhydride. A blend of 95% olefin and 5% PETG / maleic anhydride was extruded into a fiber mass using conventional fiber extrusion equipment. The fiber has a dpf of 1.8 and is cut to 1.5". Approximately 1,000 lbs of fiber are produced and packaged. The denier per filament is close to that of cotton and hence the cotton filament length.

[0102] b) Dye-enhanced olefin bales of lengths of fibers are mixed together during the carding process and made into an intimate blend of rovings. The roving made on conventional cotton equipment was ring spun to 10 / 1 cotton count and wound on 3 lb wraps. Approximately 1000 lbs of yarn are produced.

[0103] c) Knit 10 / 1 olefin yarn on a 10 gauge (cut) circular knitting machine. This manufacturing process results in an undyed gray fabric that is ideal ...

Embodiment II

[0107] Example II - Shades on Tinted Olefin Fabrics

[0108] a) Intimately mixing and grafting olefin pellets having a melt flow index of 8-22 with the above-mentioned olefin dye enhancing blend. The mixture is 95% olefin with 5% disperse dye enhancing concentrate consisting of PETG and maleic anhydride as described in this invention. The mixture is extruded into a fiber mass using conventional fiber extrusion equipment. The dpf was 1.8 and cut to 1.5". Approximately 1,000 lbs of fiber were produced and packaged. The denier per filament was close to that of cotton and thus the length of cotton filament. This batch was referred to as "Fiber A".

[0109] b) Olefin pellets having a melt flow index of 8-22 were intimately mixed and grafted with the olefin dye enhancing blend described above. The blend was 97% olefin with 3% disperse dye enhancing concentrate consisting of PETG and maleic anhydride as described in this invention. The mixture is extruded into a fiber mass using...

Embodiment V

[0125] Example V - Dyeing and printing at intervals on the yarn using the Knit de Knit process dye

[0126] a) Extrude olefin pellets having a melt flow index of 8-22 and intimately mix with the blend using the above preferred PETG and maleic anhydride mixture. A blend of 95% olefin and 5% PETG / maleic anhydride was extruded into a fiber mass using conventional fiber extrusion equipment. The fiber has a dpf of 1.8 and is cut to 1.5". Approximately 1000 lbs of fiber are produced and packaged. The denier per filament is close to that of cotton, so it is the cotton filament length.

[0127] b) Olefin bales of lengths of fibers are mixed together during carding and made into rovings. The roving made on conventional cotton equipment was ring spun to 10 / 1 cotton count and wound on 3 lb wraps. Approximately 1000 lbs of yarn are produced. A 10 / 1 grafted olefin was folded to make a 10 / 2 dyeable olefin.

[0128] c) Knit Sleeves - Knit 10 / 2 Olefin Yarn into single cuff sleeves.

Abstract

A disperse dyeable fiber or filament is comprised principally of polyolefin modified with PETG to accept the disperse dyes. The combining of maleic anhydride with the PETG provides good dispersion of the PETG for uniform dye results. Novel textile fabric, knitted, woven and non-woven, can be formed with yarns or fibers formed in accordance with the invention. In one aspect of the invention, fabric can be disperse dyed to a light, medium or deep solid shade. In another aspect, the textile fabrics are manufactured using olefin yarns that contain variable amounts of dye acceptor additives. A fabric with more than one tone of a color thus can be dyed in a single dye bath. The fabrics and yarn according to this invention can be processed using conventional spinning, weaving, knitting, web formingl machines and will dye using existing dyeing and finishing systems. This invention is of particular value in the apparel and home furnishings industry.

Description

Background of the invention [0001] The present invention relates to fabrics made using olefinic fibers or yarns modified to be dyed with disperse dyes. These fabrics are conventionally colored with existing disperse dyes or printing systems. Obtain single shades or multiple shades in the same dyebath or dyeing application. Fabrics in the present invention are manufactured as greige goods by knitting, weaving or non-woven processes. A single color is achieved by grafting one level of dye additive into the olefin yarn and passing the fabric through a disperse dye bath. Various yarns, each containing a different percentage of dye additive, were fabricated into fabrics. The fabric will be dyed in multiple shades in the same dyebath. By increasing the amount of disperse dyeable additive in the olefinic yarn or fiber, the affinity for disperse dyes increases correspondingly. Fabrics produced according to the invention can be stored in dyeing factories in undyed form. Color is ...
