Benefits of technology

Creating hybrid yarns by twisting together low denier ultra-high molecular weight polyolefin fibers and non-polyolefin fibers has resulted in products that are strong and durable, with desirable look and feel. These yarns create products that are lightweight, thin, and cost-effective, making them useful in a wide range of industries.

Problems solved by technology

Such low strength fibers are very comfortable and are easily colored to be given a fashionable appearance, but they are also known to have relatively poor durability and wear resistance.
Therefore, fabrics formed from these low strength fiber types are not ideal for use in apparel that will be subjected to extreme wear conditions, such as protective clothing for motorcyclists, bicyclists, skateboarders, industrial workers, or the like.
However, leather articles having the desired level of durability and wear resistance must be quite thick, which makes the material very heavy and potentially uncomfortable for the user, so they too are not ideal.
However, their abrasion resistance properties remain insufficient for extreme protective clothing applications, such as motorcyclists.
The different fiber types are not blended together because polyolefin filaments positioned in the interior of the blended yarn rather than at the surface do not aid in improving abrasion resistance and therefore are wasteful and even deleterious to the desired fabric properties where a balance of properties is needed, such as softness, low weight and dyeability, which are properties provided by the non-polyolefin fiber types.

example 1

[0063]A denim fabric of this disclosure was made by weaving together a plurality of twisted, non-blended composite yarns of the disclosure in a twill weave. Each twisted, non-blended composite yarn was made from three fiber / yarn types. The three fibers / yarns used to form each composite yarn of the twill woven fabric were two cotton yarns and one ultra-high molecular weight polyethylene (UHMWPE) fiber. Cotton yarns are spun yarns which are made by spinning together (or otherwise joining) a plurality of cotton staple fibers into the form of a single yarn, as is conventionally known in the art. Such cotton yarns are commercially available in several varieties. The UHMWPE fiber used for all of these examples were 400 denier, continuous filament, multi-filament SPECTRA® S-1000 fibers having a tenacity of 36 g / denier, commercially available from Honeywell International Inc. However, any fibers available the SPECTRA® trademark are useful herein as well as other polyolefin fiber brands, inc...

[0066]Similar to Example 1, another denim fabric was woven in a 3×1 LH twill weave construction with composite yarns having two cotton yarn components and one SPECTRA® fiber component. The composite yarn used in the warp direction had two 24 ECC cotton yarns that were dyed deep blue with a reactive blue dye and the SPECTRA® fiber was a black 400 denier fiber. The composite yarns used in the weft direction included two 24 ECC white cotton yarns (dyed white and / or bleached and / or naturally white (undyed)) and the SPECTRA® fiber was a white 400 denier fiber. In each of Examples 1 and 2, the hybrid yarns had the following properties:

example 3

[0067]The front faces and rear surfaces of the twill woven fabrics of Examples 1 and 2 were tested for abrasion resistance according to ASTM D4060 using an H-18 testing wheel and a 1000-gram load weight. Compared to a standard cotton denim fabric fabricated with 100% cotton (all warp and weft threads being 24 ECC cotton yarns in a 3×1 LHT construction), the abrasion resistance of the denim fabrics formed from the hybrid (composite) yarns of this disclosure was substantially improved, increasing from 467 cycles to failure (standard cotton denim fabric) to 6968 cycles to failure (denim fabric with all warp and weft threads being the twisted, non-blended hybrid yarns as outlined in Tables 1-3) when comparing abrasion resistance at the front faces of each fabric type, and from 407 cycles to failure (standard cotton denim fabric) to 4879 cycles to failure (the same denim fabric with all warp and weft threads being the twisted, non-blended hybrid yarns as outlined in Tables 1-3) at the re...

Abstract

Twisted, non-blended hybrid yarns are provided that are suitable for the fabrication of abrasion resistant garments and other textile articles. One or more polyolefin fibers are ply twisted together with one or more non-polyolefin fibers in a manner that utilizes the properties of each fiber type. A plurality of the twisted, non-blended hybrid yarns is then woven or knitted into fabrics, such as twill woven denim, or formed into ropes, such as braided ropes.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the benefit of co-pending U.S. Provisional Application Ser. No. 62 / 753,606, filed on Oct. 31, 2018, the disclosure of which is incorporated by reference herein in its entirety.BACKGROUNDTechnical Field[0002]This technology relates to hybrid yarns and articles made from the hybrid yarns.Description of the Related Art[0003]High performance fibrous materials formed from high strength fibers are well known in various industries. High tenacity fibers, such as SPECTRA® polyethylene fibers or aramid fibers such as KEVLAR® fibers, are well known as useful for the formation of high performance armor articles because of their very high strength to weight performance, good wear resistance, cut resistance and slash resistance at low fiber volumes. In recent years, the use of such high performance fibers has been extended to various non-armor industries, such as textile industries that fabricate wearable textile articles such as...
