Benefits of technology

[0009]One or more embodiments of the present disclosure concern a process for producing an effect yarn. Generally, the process involves: (a) providing an unmixed yarn bundle comprising a plurality of continuous filament singles yarns; (b) entangling the continuous filament singles yarns of the unmixed yarn bundle to thereby form an entangled yarn bundle; and (c) twisting the entangled yarn bundle in a twist jet assembly having a first twisting jet and a second twisting jet so as to twist the continuous filament singles yarns of the entangled yarn bundle about each other in alternate S-directions and Z-directions to thereby produce an effect yarn comprising a plurality of S-direction twist sections, a plurality of Z-direction twist sections, and a plurality of non-twisted entangle

example 1

[0069]A heathered helix effect yarn was produced and used to manufacture a heathered helix carpet that was tufted on a 1 / 10″ G and that contained 40 stitches per 10 cm and a pile weight of 560 gm / m2. The carpet was cut into four sample sizes of 50 cm×50 cm and then subjected to appearance retention testing (hexapod at 12,000 turns) according to ISO 10361:2015 and ISO 9405:2015. The carpet produced from the heathered helix yarn exhibited an average change in appearance of 3.0 in the lengthwise and widthwise directions, as measured according to ISO 10361:2015. Additionally, the carpet produced from the heathered helix yarn exhibited an average change in color of 3 to 4 in both the lengthwise and widthwise directions, as measured according to ISO 9405:2015. Thus, as demonstrated by this data, the heathered helix effect yarns were able to manufacture carpets that may exhibit colorful properties that may be durable and long-lasting.

example 2

[0070]A heathered helix effect yarn formed from polyamide 6,6 and comprising a total denier of 1,200 was used to produce carpet having a pile weight of about 350 gm / m2.

[0071]As shown in TABLE 1, below, the heathered helix yarn was tufted to various substrates to produce the test carpets. The produced carpet samples were then subjected to Color Core TARR tests (as measured according to ASTM D5252). As shown below, these test results demonstrate that the heathered helix yarns can produce carpets that exhibit desirable durability and color retention.

Abstract

A process is provided for the manufacture of an effect yarn, such as heathered helix yarns, for use in carpets, floorcoverings, and textile articles. The effect yarns contain patterned alternating sections of twisted multiple singles yarns and sections of entangled multiple singles yarns. More particularly, these effect yarns may comprise a plurality of S-direction twist sections, a plurality of Z-direction twist sections, and a plurality of non-twisted entangled sections interspersed between the S-direction twist sections and the Z-direction twist sections.

Description

RELATED APPLICATIONS[0001]This application claims the priority benefit under 35 U.S.C. § 119(e) of U.S. Provisional Patent Application Ser. No. 63 / 021,372 entitled “HEATHERED HELIX YARNS,” filed May 7, 2020, the entire disclosure of which is incorporated herein by reference.FIELD OF INVENTION[0002]The present invention generally relates to a process and system for producing and making yarns. More particularly, the present invention is generally related to the production of yarns, which may be used to manufacture a carpet, a floorcovering, and / or a textile, that exhibit one or more aesthetically beneficial coloration effects.DESCRIPTION OF THE RELATED ART[0003]Undrawn, essentially unoriented, and partially oriented yarns (“POY”), melt spun from thermoplastic polymers, may provide yarns that are described in the art as “flat,” i.e., the filament bundles are essentially linear, and have little shape retention ability or resilience towards deformation processes. As such, these yarns hav...
