Description
Technical Field
The utility model relates to a covering yarn, especially an ultra high molecular weight polyethylene spandex covering yarn.
Background
The ultra-high molecular weight polyethylene fiber has excellent physical and chemical properties and is characterized in that: (1) low density: 0.97/g cm -3 Lighter than water, and can float on the water surface. (2) high strength: tensile strength > 3.00GPa, specific strength > 3.09 N.tex -1 Higher than aramid fiber and carbon fiber. (3) Chemical corrosion resistance, namely seawater resistance, strong acid resistance, strong alkali resistance and organic solvent resistance. (4) the coating has ultraviolet resistance. The industrial application product of the ultra-high molecular weight polyethylene fiber is mainly a filament product: the product comprises bulletproof UD cloth, stab-resistant clothing fabric, cutting-resistant gloves, various ropes, fishing nets and the like. The ultra-high molecular weight polyethylene fiber is a high-strength fiber with excellent performance, but the surface of the ultra-high molecular weight polyethylene fiber is smooth, the friction factor is small, and the crimp stability is poor. The spun staple fiber yarn has lower yarn strength and poorer yarn quality.
Because the moisture regain of UHMWPE is 0, the comfortableness is poor, and for products directly contacting with the skin of a human body, the defect that protective articles such as gloves, socks and the like directly produced by using pure UHMWPE filaments is obvious in the aspects of comfortableness and application range. The core-spun yarn spinning technology is mature, UHMWPE filaments can be completely used as core yarns, and the UHMWPE filaments and the cotton core-spun yarns can be spun by the outer-wrapping cotton fibers to meet the production of special labor protection articles, so that the characteristics of light weight, super strength and super comfort of the UHMWPE filaments and the cotton fibers can be fully exerted, and the function complementation is realized, so that the application range of products of the UHMWPE filaments is expanded.
CN104532431 reports that in order to reduce the exposure of core-spun glass fiber, inner and outer layers are reversely coated, firstly 100D glass fiber low-elasticity filament is coated with extremely high twist to 12000 twist/m, then 400D ultra-high molecular weight polyethylene filament is reversely and highly twisted to be coated (to 8300 twist/m), and 105D spandex is coated with 200D polyethylene filament, and then the two materials are used for producing labor protection gloves by a double-layer knitting method. The coating method has extremely low efficiency, the price of the 200d ultra-high molecular weight polyethylene fiber is high, and the raw material cost and the production cost are very high.
The aramid fiber has the characteristics of high strength and high modulus, wherein the strength of the aramid fiber 1414 can reach more than 22CN/dtex, and is 3 times of that of steel, and is 4 times of that of the high-strength polyester industrial yarn. Thus, aramid 1414 is the best choice for cut resistant fabrics, which has deficiencies in moisture absorption.
How to make the cutting-resistant covering yarn have good hand feeling and moisture absorption performance becomes a problem to be solved.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing an ultra high molecular weight polyethylene fibre/spandex covering yarn when possessing and preventing cutting performance, still has good compliance and elasticity to have good moisture absorption performance.
In order to solve the technical problem, the purpose of the utility model is to realize like this:
the utility model relates to an ultra-high molecular weight polyethylene fiber/spandex core-spun yarn, which comprises a core wire, a first coating layer, a first wrapping layer and a second coating layer; the first coating layer is coated on the outer side of the core wire, the first coating layer is coated on the outer side of the first coating layer, and the second coating layer is coated on the outer side of the first coating layer;

Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments.
Example one
This embodiment will be described in detail with reference to fig. 1. The ultra-high molecular weight polyethylene fiber/spandex core-spun yarn related by the embodiment comprises a core wire 1, a first coating layer 2, a first wrapping layer 3 and a second coating layer 4; the first coating layer 2 is coated on the outer side of the core wire 1, the first coating layer 3 is coated on the outer side of the first coating layer 2, and the second coating layer 4 is coated on the outer side of the first coating layer 3.
In the present embodiment, the core yarn 1 is a spandex filament, and the fineness of the selected spandex filament is 40D. The first coating layer 2 is made of ultra-high molecular weight polyethylene short fibers. The fineness of the used ultra-high molecular weight polyethylene short fiber is 1.21dtex, and the length is 38mm; the first wrapping layer 3 is aramid fiber 1414 filaments; the second coating layer 4 is cellulose fiber, and the specific cellulose fiber is flame-retardant viscose fiber.
Example two
This embodiment will be described in detail with reference to fig. 2. The difference between the ultra-high molecular weight polyethylene fiber/spandex core-spun yarn related to the embodiment and the embodiment one is that: in the second coating layer 4 a number of fibre attachment points 6 are randomly arranged. The fiber bond points 4 used are formed by heating the ES fibers. The surface layer of the ES fiber is low-melting-point fiber, and after high-temperature treatment, the outer layer of the ES fiber is melted, and the fibers around the ES fiber can be bonded, so that the strength of the whole yarn is increased. And if the fiber adhesion points 4 arranged on the coating layer of the outermost layer can enable the coating yarn to float fibers, the possibility of fluffing and pilling can be reduced.
EXAMPLE III
This embodiment will be described in detail with reference to fig. 3. The difference between the ultra-high molecular weight polyethylene fiber/spandex core-spun yarn related to the embodiment and the embodiment one is that: a third coating layer 5 is arranged on the outer side of the second coating layer 4; the third coating layer 5 is a PAN micro-nanofiber membrane. PAN is hydrophilic polyacrylonitrile. Firstly weighing a certain amount of PAN powder and DMF solvent, preparing 12% PAN/DMF solution by mass fraction, stirring at room temperature for 12h by using a magnetic stirrer, standing, and coating PAN micro-nanofiber on the outer side of the second coating layer 3 by adopting an electrostatic spinning method. And the water absorption performance of the core-spun yarn can be effectively improved due to the use of the cotton fiber and the PAN micro-nanofiber membrane layer. And the use of PAN micro-nanofiber membranous layer can effectively reduce the number of floating fibers in the cotton fiber in the second coating layer 3.
The foregoing has described in detail preferred embodiments of the present invention.
