Description
Technical field
The invention belongs to special yarn line technology field, be specifically related to a kind of high temperature resistant anti-cutting complex yarn, and relate to the application of this yarn
Background technology
are present, give an example being not limited to and typical high temperature occasion such as iron and steel manufacturing and sharp operating mode occasion (working environment) generally to use with the asbestos fibre like the glassware manufacturing be the main thread protective articles of composite yarn.Though asbestos have strong points such as good high temperature resistant, rub resistance, low price, light specific gravity, thermal conductivity factor low (thermal conductivity factor is 0.198-0.244W < mk >) and conductance be low; But; Because asbestos have carcinogenic and environment are had contaminative human body; Therefore the production and the use that comprise the asbestos friction material of protective articles more and more are restricted, even are under an embargo in many developed countries and even developing country.
The TECHNICAL INFORMATION SOURCES of high temperature resistant yarn can be seen in
in disclosed Chinese patent document; For example CN201534902U recommends to have " the sunshade lining of high flame retardant complex yarn and application thereof "; It is outside the fiber filament bundle, to coat fluoroplastics to form shape of cross section be concentrically ringed shape, and still, this yarn does not belong to spinnability yarn category; And can't put into common loom weaves; Especially be not suitable for processed and applied in aforesaid protective articles such as iron and steel, glassware manufacturing, though because this yarn has desirable anti-flammability, the environment-friendly advantage of low-smoke low-toxicity, but very fragile for the sharp intensity of opposing with self.
again; " the macromolecule composite yarn " that CN201241223Y provides remedied the shortcoming of CN2670389Y disclosed " the fabric fluff type yarn of nonwoven "; Have good tensile strength, but do not have the achievement part for fire-retardant, high temperature resistant, anti-cutting etc.
reach; " complex yarn of anti-cutting " that application for a patent for invention publication No. CN102308035A introduces is to be that hard component and the continuous elastomer yarn of the many hard fibres of 25 μ m constitutes by average diameter; Hard component is the gel spinning silk thread of ultra-high molecular weight polyethylene and/or the yarn of staple fiber, and elastomer yarn is processed by the long-chain synthetic polymer of inclusion block polyurethane.Can know from the description of the specification the 0011st section to 0037 section (especially the 0035th section and 0037 section) of this patent application; The complex yarn of this anti-cutting belongs to the yarn category of processing dress ornament class; Though do not belong to aforesaid extraordinary yarn category, promptly should not use as the protective articles of high temperature, sharp operating mode occasion.
In sum; In disclosed patent and non-patent literature or in the aforementioned occasion (high temperature, sharp operating mode occasion) of reality, all be not seen in not only to have high temperature resistant and anti-flammability of standing out from one's fellows but also the teachings that has the yarn of ultimate attainment anti-cutting performance concurrently no matter be; The applicant has done long-term and useful exploration for this reason, and the technical scheme that will introduce below produces under this background
Summary of the invention
task of the present invention is to provide a kind of to be had the high temperature resistant and anti-flammability of standing out from one's fellows and uses to satisfy and be used to process the high temperature resistant anti-cutting complex yarn that the protective articles that uses down such as high temperature and sharp working environment and flexible transmission part require.

task of the present invention is accomplished like this; A kind of high temperature resistant anti-cutting complex yarn; Comprise and tangle with center fiber as the center fiber of inner core with through twisting and be coated on the outer covered fiber of center fiber; Be characterised in that: described center fiber shared mass percent in said complex yarn is 30-70%; And described covered fiber shared mass percent in complex yarn is 70-30%, and described center fiber is chemical long filament, and described covered fiber is the Fanglun l414 short fiber.
in a concrete embodiment of the present invention, the fiber number of described Fanglun l414 short fiber is 1.5-3.2dtex, and the length of fiber is 20-150 ㎜, and intensity is 17-18.5cN/dtex, modulus>=500cN/dtex.
in another concrete embodiment of the present invention, the intensity of described chemical long filament is 2-3cN/dtex, and fiber number is 55-330dtex.
in another concrete embodiment of the present invention, described chemical long filament is glass fibre, polyester fiber or polyamide fiber.
in another concrete embodiment of the present invention, described polyester fiber is a h, and described polyamide fiber is the high strength polyamide fiber.
also have among the concrete embodiment of the present invention, and described h is for being added with the h of inorganic particle in polyester slice; Described high strength polyamide fiber is for adding the high strength polyamide fiber that inorganic particle is arranged in the polyamide section.
are more of the present invention and among concrete embodiment, described inorganic particle shared percentage by weight in said polyester slice is 0.1-4%; And described inorganic particle shared percentage by weight in described polyamide section is similarly 0.1-4%.
in of the present invention and then concrete embodiment, described inorganic particle is that Mohs' hardness is nano titanium oxide or the nano silicon of 0.25-5 μ m greater than 3 grades with particle diameter.
of the present invention again more and among concrete embodiment, the specification of said complex yarn is 10S-60S.
also task of the present invention is accomplished like this; A kind of application of high temperature resistant anti-cutting complex yarn supplies knitting or woven being made into to be used to make the gloves, apron and the protective clothing dress ornament that use under high temperature and the sharp operating mode with lining and transport tape.
The resulting high temperature resistant anti-cutting complex yarn of
technical scheme provided by the invention is because covered fiber is a Fanglun l414 short fiber and middle core fibre is chemical long filament; The strong point of anti-cutting of excellence of the high temperature resistant and anti-flammability of standing out from one's fellows and the chemical long filament of Fanglun l414 short fiber is gathered in one; The lining that uses this complex yarn to be processed into can satisfy the instructions for use under high temperature, sharp working environment, uses and embodies safety and durable result of use.
