Description
Technical field
The present invention relates to a kind of ultra high molecular weight polyethylene fibers, and in particular to a kind of High molecular weight polyethylene is network combined
Yarn.
Background technique
The soft chain high polymer that ultra high molecular weight polyethylene fiber is made of methylene, molecular structure is regular, takes with height
It is current specific strength and the highest high-performance fiber of specific modulus to degree and high-crystallinity.Ultra high molecular weight polyethylene fiber due to
Its special chemical structure and have the advantages that much protrude, such as good chemical corrosion resistance, hydrophobicity, uviolresistance,
Anti- cutting, wearability, thermal conductivity etc., but there are also disadvantages, especially because molecular chain structure is single, do not contain polar group
Group, fiber surface is smooth, and friction factor is small, and moisture absorbing and sweat releasing property is poor, and dyeing is difficult, expensive, answers in civilian field of textiles
With there is certain limitation.
Improving ultra high molecular weight polyethylene fiber main method of application in civilian weaving is and other fiber blends
Complex yarn is made.Complex yarn refer to by the fibrous raw material of two or more identical or different performance be learn from other's strong points to offset one's weaknesses and
It is combined together, forms the new type yarn that can give full play to respective function.Common complex method has short fiber blending technique to add
Work staple blended yarn and it is short it is fine with it is short it is fine, short it is fine twisting complex yarn is made by twisting mill with long filament, long filament and long filament, and
The network combined yarn of ultra high molecular weight polyethylene fiber is there is not yet open.Short fiber blending technique process is complicated, need to be by long filament
It is first crimped, is formed, cuts off, shredding, carding are then carried out with other staple fibers into item, fine sand, the multiple working procedures such as post-processing
It is just able to achieve, and compound spun yarn loss of strength is larger.It is relatively simple to twist combination process process, but needs to set by twisting
Standby to prepare complex yarn, at high cost, low efficiency the reason of additionally, due to yarn twist, easily makes composite yarn harden, produces and knit
Object flexibility and drapability are affected.
Summary of the invention
Goal of the invention：In view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to provide a kind of High molecular weight polyethylene net
The monofilament coherent of network complex yarn and preparation method thereof, high production efficiency, complex yarn is good, has both ultra-high molecular weight polyethylene
The easy weaving of the characteristics and other fibers such as the cool feeling of fiber is comfortable, high-strength, wear-resisting, cut resistant, chemical inertness, suitable for taking equal spies
Property, improve ultra high molecular weight polyethylene fiber in the application of civilian field of textiles.
Technical solution：A kind of network combined yarn of ultra-high molecular weight polyethylene is 10% ~ 90% by including weight percent
Ultra high molecular weight polyethylene fiber and 10% ~ 90% the yarn with network structure that is combined of civilian textile fabric, yarn
Network number be 10 ~ 100/meter.
Further, the ultra high molecular weight polyethylene fiber is the white or coloured yarn of 50D ~ 600D, and filament number is
0.5dtex~5dtex。
Further, the civilian textile fabric includes the long filament of terylene, polyamide fibre, polypropylene fibre, viscose glue, PBT, spandex, acrylic fibers, single
Silk size is 0.1dtex ~ 5dtex.
Further, ultra high molecular weight polyethylene fiber is subjected to relaxation heat setting, heater temperature by an at least section hot tank
It is 100 DEG C ~ 150 DEG C, then carries out non-twist and close with civilian textile fabric, passes sequentially through tensioner, one or more network sprays
Mouth, oiling machine, final coiling and molding；Wherein, apply air pressure in network nozzle, using the effect of jet-stream wind, fiber is mutually twined
Knot, forms periodic nexus, network combined yarn is made.
Further, after fibre untwisted and conjunction, network over feed rate(OFR) 0.5% ~ 10%, air pressure is 0.1 ~ 0.8MPa, processing speed
Degree is 100m/min ~ 600m/min.
Beneficial effect：1, the composite fibre with network improves ultra-high molecular weight polyethylene long filament and other fibers
Between coherent difference problem, since ultra-high molecular weight polyethylene filament tow is smooth, without cohesive force or cohesive force very little,
It is easy to happen folded silk when winding, knocking over and turned-down edge etc., when unwinding are easy to produce spider web, occur part monofilament in tow motion process
Relaxation, accumulation or blocking fiber guiding element, or even cause to break end, network combined yarn has periodic nexus, can effectively solve
Certainly because unwinding problem caused by monofilament coherent difference.
2, different from the preparation method of general networks complex yarn, ultra high molecular weight polyethylene fiber because its surface is smooth,
It is not easy to crimp, generates entanglement with other fibers by being not easy in network nozzle recombination process, or tangle and easily unclamp.Therefore in net
Before network is compound, ultra high molecular weight polyethylene fiber need to first pass through at least one section of hot tank, carry out relaxation heat setting, have fiber micro-
Micro- rolled state, then the effect through jet-stream wind make it easier to intertwine with each other with civilian textile fabric, and being formed includes regular interval
Fibrillation portion and interlacing portion network combined yarn, complex yarn have good bulkiness and elasticity.In addition, super high molecular weight
The network section of polyethylene network complex yarn is a kind of false twisting, and after weaving or dyeing process processing, subnetwork festival-gathering is de-
It opens, the flexibility and drapability of fabric are obviously improved.
3, the network combined yarn of ultra-high molecular weight polyethylene has both the high-strength and high-modulus characteristic of ultra high molecular weight polyethylene fiber
The characteristics of being suitable for textile field with other fibers, complex yarn is soft, and moisture absorbing and sweat releasing property is good, intensity and wearability
Height, colouring is easy, knitting property is good；The thermal coefficient of ultra high molecular weight polyethylene fiber is 4 times of terylene, therefore network combined
Yarn has good coolness.
4, compared with staple blended yarn line and long filament twisting complex yarn, simple process and low cost, high production efficiency.
Network technique can be improved 60 times than twisting method process velocity, and cost reduces by 70%.
5, the network combined yarn can be used for various textile products, and especially have ice-cold comfort need takes home textile neck
Domain, such as labour protection dressing, gloves, cool feeling bed necessaries, automobile cushion, insole, sportswear, movement knapsack equipment.
