Definitions
- the preferred coating material is a copolymer of ethylene vinyl acetate, and is applied to the backing by any known method including spraying, immersing, brushing or rolling.
- the present invention relates to improvements in the preparation of tufted products, e.g., carpets or the like, which include a backing, partially or wholly comprised of a woven fabric.
- the present invention relates to tufted products of the type referred to wherein the woven backing is coated by known methods which renders the finished, tufted product highly resistant to tuft raveling when such tufted product is applied to its end use as a carpet or floor covering.
- woven backings comprising yarns of synthetic thermoplastic materials such as the polyolefins, polyethylene and polypropylene.
- These backings of woven polyolefin yarns are, in most instances woven from yarns of substantially ribbon-like character, especially in the warp.
- the backings, after weaving are fed into a multi-needle tufting machine which sews or otherwise inserts tufts of face yarn, into the backing.
- the face yarns may be any of the materials above referred to or made from nylon, acrylic fibers or natural fibers.
- Tufted pile fabrics produced from woven polyolefin backings have exhibited in the past, an undesirable tendency to ravel at a cut edge paralle to the tufting stitching line. This ravelling occurs when a force is applied perpendicular to the stitch line at the cut edge. Since in tufting the stitch line in carpets is most often parallel to the warp yarns of the primary backing fabric into which the face or pile yarn is tufted, the edge row of stitches along a cut tends to pull out sideways as the warp yarns of the backing fabric slide across the fill yarns of the backing.
- Carpets provided to the trade usually have a rubber latex (adhesive) coating applied to the back of the tufted pile fabric as noted above. While this, by itself, tends to reduce tuft ravelling with woven backings of the type in which this invention is concerned, it, the latex lamination procedure, must be performed properly, or tuft ravelling resistance of the finished carpet will be unacceptable, even for commercial or contract ing into which the face yarn is tufted, since nonwoven backings inherently have excellent resistance to tuft ravelling. Woven backings would likewise be suitable for such end uses in commercial grade carpet if such tuft ravel resistance could be significantly improved.
- Woven backings have certain advantages over nonwoven, as for example a tufted pile fabric with a nonwoven backing exhibits undesirable greater stretching when tensioned, because its modulus of elasticity is considerably lower than a woven backing carpet, which, as will be seen, is important in later steps of car pet manufacturing.
- a backing woven from yarns of synthetic, thermoplastic materials wherein the tuft ravelling resistance is significantly improved over prior art backings.
- Another object of this invention is to provide a woven backing for tufted pile fabrics wherein the backing receives a coating which effectively stabilizes the fabric (i.e., decreases its sleaziness) by bonding the yarns and reduces tuft ravelling of the finished carpet thereby providing an acceptable commercial product.
- the coating applied is selected from a group of materials, the most preferred one being a co-polymer of ethylene and vinyl acetate.
- a primary backing for a carpet product is woven from yarns of synthetic plastic.
- the synthetic plastic is comprised of any of those plastic materials capable of formation into weavable yarns, including, but not limited to, polyethylene, polypropylene ethylene/propylene copolymers, copolymers of other alpha-olefins, polyesters, polyamides, cellulose acetate and polyvinyl chloride.
- the backing is coated with a polymeric compound which is dried and cured, after which a lubricating material can, if desired, be applied, usually to one side.
- a lubricating material can, if desired, be applied, usually to one side.
- the lubricant can be applied before coating, or to the yarns, either the warp or the fill or both, prior to weaving.
- a still additional alternative is to apply both the coating and the lubricant simultaneously, ei-
- the amount of lubricant needed will vary according to the lubricant used, the primary backing to be treated and the type of tufting operation. In general it has been found that the specified fabric strength can be obtained by treating the synthetic plastic primary backing material (for example primary backing materials like those disclosed above) prior to tufting with at least so much lubricant that the tufting needles are enabled to pierce the individual yarns in the backing fabric without rupturing or shattering them. Generally from 0.2 to 12 percent, and preferably 0.6 to 8 percent by weight, of the lubricant will be used.
- the lubricant used can be any lubricating substances that does not react with, have solvent action on, or otherwise materially affect the properties of the synthetic plastic yarns in the primary backing.
- Suitable materials include, for example mineral oils; ethoxylated higher fatty acids (i.e., fatty acids having eight or more carbon atoms) more commonly known as polyethylene glycol esters, e.g.
- the lubricant should be a relatively low viscosity liquid either as such or when in aqueous emulsion, so as to provide easy application and spreading.
- the most especially preferred lubricants are mineral oil. ethoxylated castor oil, and the polyethylene glycol esters, especially polyethylene glycol oleate having an average of oxyethylene (CH CH O-) groups per molecule commercially sold under the tradename Nopcostat 2l52-P. Nopcostat" is a Registered Trade Mark.
- Another material useful as a lubricant is a mixture of calcium stearate and silicone oil, the latter being present in minor amounts.
- the thus treated backing now possessing ample strength retention after tufting, is coated before tufting with one of a number of materials, such as the dispersions in water, or other agents or polyethylenes, carboxylated styrene polybutadiene rubbers and acrylic latexes in addition to the ethylene vinyl acetate copolymer, which have been found to survive the impact imparted by the tufting needles.
- Backing strength is needed also because subsequent operations on the fabric such as dyeing, drying and latexing above referred to tend to weaken the fabric resulting in an unsatisfactory carpet product.
- a dispersion of polyethylene in water, with a small amount (0.05 percent) of a 2% gel agent, a styrene maleic anhydride polymer and a latex was found to provide a tufted pile fabric of good tuft ravel resistance with little or no loss in tufted fabric strength as compared to an uncoated, lubricated woven polyolefin backing.
- latexes of carboxylated styrene butadiene rubber have also provided improved carpets when coated on a woven, lubricated or unlubricated backing used to receive tufts of face yarns.
- Other acrylic latexes applied to the backing after weaving can also perform well in the finished carpeting from the standpoint of improving the characteristics of the backing to prevent or minimize tuft ravelling during the installation of the finished carpet product.
- ethylene vinyl acetate copolymer one is selected having a softening temperature in the range of [F to 200F, so that when coated onto a lubricated or unlubricated backing, resealing of any ruptured yarn bonds caused by tufting occurs at 230F to 280F, which temperature range will be encountered by the backing in the drying of the carpet product after dyeing and/or latexing.
- Another advantage obtained is that since there coatings are compatible with practically all presently used latex materials including the final, or finish underside materials, the invention is readily adapted over a broadrange of applications.
- woven backings when coated according to the invention achieve a high degree of stabilization, by which is meant that objectionable sleaziness is eliminated thereby imparting to the backing better body so that, in tufting operations, its handling characteristics are much improved.
- inventive backings herein set forth can be readily used in carpets having secondary backings, even when such secondary backings are made from jute, or other natural fibers with no harmful effects. In fact, such carpets will likewise enjoy all of the advantages hereinbefore set forth.
- EXAMPLE l A woven polypropylene backing fabric having a weave configuration of 22 ends per inch of ribbon yarn in the warp and l 1 ends per inch of substantially round multifilament ends in the fill (Sample A, Table l) was coated on a textile padder and fused dried in a tentering frame at 310F. The coating used was applied by immersion in a bath and picked up through a wringer to squeeze out extra coating. The coating solution was: Microfene FE-530 ethylene vinyl acetate copolymer made by the US Industrial Chemical Co.
- Tuft ravel resistance determined as follows: pins spaced over 2" inserted into back of tuft pile sample, 4" X 4"; force to pull out measured in lbs. on an Instron tester at 12''/ Min. rate of extension. Three different values are obtained by inserting pins into first tuft row (one row pull), second row (two row pull), and 0.7 inches from edge, which is seventh row for inch gage tufting.
- Latex application oz. per sq. yd. standard latex coat on back of tufted backing.
- Foamed back high density foam rubber adhesively attached to tufted, latexed backing.
- sample D Three Samples D E and F (Table II) of laboratory pllot Scale equlpment After tuftmg compansons scale tufted pile fabrics were made, each with a differtween the control sample and the coated sample were em primary backing
- the backing of sample D was made to determine the various characteristics in partic- 40 coated with ethylgne vinyl acetate copolymer; sample ul ar, fabric strength, and comparisons were also made
- E was coated ith a olyethylene dispersion in water with a non-woven fabric (Sample C, Table I): T data with small amounts of a gel agent, latex and a styrene obtained are set forth in Table I herefollowmg. From maleic anhydride polymer.

- Each fabric was clamped in a restraining frame and wlth hon-wove" fabncother features In which placed in at 320F. hot air oven for drying and fusion of Provemeht was noted are in the important features of the coating.
- the fabrics were then tufted on a tufting tuft lock and fabric grab tensile Strength in the fill machine.
- Half of each tufted pile fabric sample was yarn direction. Although lower warp direction grab tested for ravel resistance and the other half was strength is noted, it is of little or no concern since warp mock-dyed before testing.
- Mock dyeing was accomgrab strength is not critical and is proportional to the plished in a laboratory dye beck, and included boiling reduction in the number of warp ribbons in coated fabfor 2 hours with the fabric sample in a roping condiric as compared to the uncoated fabric. Therefore betion in a typical nylon dispersed dye formulation with cause fewer warp ends per inch are present in the the dye stuffs omitted.
- a dye beck is an open trough coated fabric than in the control fabric, it is expected containing the dye liquid and the carpet material is a lowering in grab strength would occur. However, it moved in and out of the liquid by a mechanism well should also be noted that the number of ends per inch known to the art.

- Mock dyed exposed to all conditions of a disperse dyeing procedure except no dyestuffs were used.
- Tufting Natural nylon bulked continuous filament, 3600 denier. /16 loop pile, /32 gage, 8% stitches per inch.
- Table 111 sets forth the results obtained from the data.
- EXAMPLE IV Sample G of woven polypropylene fabric of a weave configuration of 30 ends per inch of 500 denier ribbon in the warp and 1 1 ends per inch of 1 100 denier ribbon in the fill was spray coated with a latex containing a solids to water ratio of 1 to 3 and air cured in an oven at A fabric prepared in a manner similar to any of those of Example IV was tested to determine tufted grab strength in the fill direction, the most critical strength requirement in the manufacture of carpets. This tudted fabric sample was coated with 0.44 oz./sq. yd. of coating and had a grab strength of 56 lbs. The tufted uncoated control fabric had 67 lbs.
