Technical Field

The utility model relates to the technical field of composite yarns, in particular to a knitted anti-slip cut-resistant covering yarn.

Background

The cut-resistant class of cut-resistant gloves is determined by the woven yarn. In order to pursue a high cut-preventing grade, the pure use of a cut-preventing yarn cannot meet the grade requirement, and it is often required to use PE filaments or modified yarns thereof (such as diamond yarns produced by astronautics), metal filaments such as steel wires or tungsten wires, inorganic fibers such as glass fibers or basalt, and the like, and to achieve the high cut-preventing grade requirement by cladding or core-spun manners. However, when these high cut-resistant yarns are used directly or as surface yarns for knitting glove blanks, there are problems in that: (1) Stiff texture, poor touch feeling and skin contact feeling and poor wearing experience; (2) The knitting process is prone to slipping and this problem cannot be avoided even if blended with other yarns.

The method comprises the steps of adopting a 13-needle glove knitting machine U2 knitting method, introducing the wrapping yarns of the examples 1-7 and the comparative examples 1-3 into a main yarn nozzle, introducing a single Bao Anguan into an auxiliary yarn nozzle (taking 70D spandex as a core yarn, coating 70D nylon on the outer layer, enabling the draw ratio to be 2.6, enabling the twist to be 400 twists/m), introducing a 95# rubber thread at the hand neck position, knitting the two yarns together into a glove blank, dipping nitrile latex, and performing cutting test according to ANSI/ISEA 105-2016 standard, wherein products of the examples 1-5 can reach A7 level of cutting resistance, products of the example 6 can reach A4 level, and products of the example 7 can reach A5 level.

The coated yarns of the different examples described above exhibit different manufacturability: the core yarns of comparative example 3 and comparative example 2 were only metal filaments or only metal filaments and non-metal inorganic filaments, and although the outer cover was covered with two outer cover yarns, slippage was likely to occur between the core yarns and the outer cover yarns, resulting in uneven surfaces of the knitwear during knitting. In the process of knitting and preparing the glove blank, the wrapping yarn in comparative example 1 has loose structure, and the outer wrapping yarn and the core wire are easy to slip, so that the problem of uneven knitting effect and uneven surface of the glove blank is solved. The addition of PE filaments or modified PE filaments (diamond filaments or diamond yarns) in the core yarns in examples 1-3 increases the friction between the core yarns and the outer wrapping yarns, facilitates the knitting process, and the knitted glove blanks have flat surfaces and no pimples. Examples 4-5 the addition of cotton fiber filaments or polyester filaments to the core yarn provides a slip resistant effect, further increases the friction between the overwrap yarn and the core yarn, prevents the overwrap yarn from slipping with the core yarn, also gives the knitwear better sweat absorption and breathability, and improves the wearing comfort of the glove. In example 6, glass fiber filaments and aramid filaments are juxtaposed as core yarns, aramid filaments are regarded as slip resistant filaments, and in example 7, a bundle of metal staple fibers and diamond filaments are juxtaposed as core yarns, jin Gangsi are regarded as slip resistant filaments, so that cut-resistant covering yarns with good knitting effect can be obtained.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and not for limiting the same; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the invention.
