Description
Technical Field
The invention relates to a fabric, in particular to a blended fabric and application thereof.
Background
In the modern social life, textiles made of various fabrics are visible everywhere. With the improvement of living standard of people, the requirements of people on the fabric are not only limited to beauty, but also more the requirements on the inherent quality of the fabric. Therefore, the functionality, comfort and the like of the fabric are more and more concerned by people.
The blended fabric is generally blended by yarns with two or more components, so that the blended fabric has unique advantages. Blending is a very important means for obtaining fabrics with excellent properties.
On the one hand, there have been a number of reports of fabrics formed by interlacing blended yarns with filaments. For example, CN110387626A discloses a cool jean fabric, wherein the warp yarn is cotton and/or spandex blended yarn, and the weft yarn is modified polyethylene fiber. CN110117865A discloses a fabric, which is woven by blended yarn A and flame-retardant filament B; the blended yarn A is formed by blending flame-retardant viscose staple fibers, aramid staple fibers, chinlon staple fibers and conductive staple fibers; the flame-retardant filament B is aramid filament. CN105926118A and CN205803704U disclose a hollow far infrared polyester-cotton blended fabric, which is formed by interweaving warp yarns and weft yarns, wherein the warp yarns and the weft yarns are in a plain weave structure, the warp yarns adopt 75D common polyester filaments, and the weft yarns adopt 40S hollow far infrared polyester-cotton blended yarns. CN205295610U discloses a bright jacquard bedding fabric, which is woven by warp yarns and weft yarns according to a jacquard weave, wherein the warp yarns adopt polyester filament yarns with special-shaped cross sections, and the weft yarns adopt blended yarns of tencel and cotton. CN205046272U discloses a three-dimensional relief jacquard fabric, which is formed by interweaving warp yarns and weft yarns according to a jacquard process, wherein the warp yarns are 50D bright polyester filaments, and the weft yarns are cotton type short fibers; the cotton type short fiber is blended yarn of cotton with the fineness of 60s and tencel. CN103147208A discloses a hemp jacquard fabric, the warp is hemp blended yarn, and the weft is rayon or polyester filament. CN102560844A discloses a blended knitted fabric containing apocynum venetum fibers, which comprises apocynum venetum fiber blended yarns and polyester filament fibers. CN201817641U discloses a home textile fabric interwoven by polyester filament fibers and all-cotton yarns or polyester-cotton yarns, wherein the warp yarns are polyester filament fibers, and the weft yarns are all-cotton yarns or polyester-cotton yarns. CN101338470A discloses a micro-elastic memory fabric, warp yarns are PTT memory filaments or PET/144F fine denier filaments, and weft yarns are PTT/PET composite blended yarns or PBT stretch yarns. CN1723306A discloses a textile fabric formed from a spun yarn comprising a first staple fiber selected from aramid or polybenzimidazole or PBO or melamine formaldehyde and a second staple fiber selected from aramid polymer; the multifilament yarn comprises aramid filaments. JP2010024558 discloses a high-density fabric, wherein warp yarns are thermoplastic cellulose filament and polyester filament composite yarns, and weft yarns are polyester filaments. JP2015098656 discloses a functional fabric, wherein warp yarns are synthetic fiber filaments, and weft yarns are blended yarns of cotton fibers and high-strength high-elasticity functional fibers. JPH08232173 discloses a fabric, the warp yarn is blended yarn, and the weft yarn is easy-dyeing polyester filament.
On the other hand, the modacrylic fiber is formed by a copolymer of an acrylonitrile monomer and a vinyl compound containing halogen, has better hand feeling and higher flame retardance, and has certain acid resistance and chemical agent resistance. CN109706606A discloses a flame-retardant yarn formed by blending 60% modacrylic and 40% cotton, and a surface fabric is woven by the flame-retardant yarn and polyester yarn. CN109295593A discloses blending dyed fluorescent flame-retardant polyester fiber with modacrylic to obtain outer-coated roving, and then directly weaving. The research of the above patent documents focuses on the flame retardancy of modacrylic fibers, and does not consider the mechanical properties thereof. In fact, the modacrylic fiber has low breaking strength and tearing strength, which is not favorable for popularization and application.
In addition, CN110117865A discloses a fabric or face fabric made by interweaving high-performance filaments with blended yarns containing flame-retardant functional synthetic fibers, which uses relatively expensive aramid fibers and does not involve modacrylic fibers.
