Description

A kind of high tenacity nano carbon sol, the filter of nano-graphite irradiation grafting modified nylon monofilament Cloth and preparation method thereof
Technical field
The present invention relates to chinlon technical field of filter cloth, more particularly, to a kind of high tenacity nano carbon sol, nano-graphite irradiation Graft modification nylon monofilament filter cloth and preparation method thereof.
Background technology
《Monofilament filter cloth and its progress of performance》One literary composition describes terylene, chinlon, polypropylene, polyethylene monofilament filter cloth Performance.Monofilament filter cloth refers to the filter cloth being made into using single fiber, and conventional monofilament filter cloth typically by chinlon, terylene, polypropylene and gathers The braiding of the monfil such as ethylene forms.Compared with multifilament filter cloth, the fibre strength of monofilament filter cloth is big, good toughness, in use not Have the situation of fracture of wire；After using calendaring technology, stability is high, be unlikely to deform, aperture dense uniform；Filter cloth surface is smooth, It is difficult to block, ventilative, water permeability is good, and filter cake is easily peeled off regeneration.So, the filter efficiency of monofilament filter cloth is higher, and clearly Wash infrequently, long service life.The filtration resistance of monofilament filter cloth is relatively small, contamination resistance strong, and meeting in filtering accuracy will On the premise of asking, its combination property is better than multifilament filter cloth.
Chinlon all has very high intensity under dry, wet condition, up to 5.3cN/dtex during dry state, when wet strength is dry state 80%～90%；High abrasion resistance, is more than 10 times of cotton fiber；The percentage elongation of chinlon and elasticity are all fine, percentage elongation up to 18%～45%, when percentage elongation is 10%, elastic recovery rate is more than 90%；Alkali resistance and other medicine performances resistance to are good, molten at other More stable in agent, but acid resistance is a bit weaker；Fiber surface is smooth and hygroscopicity is strong, so easy cake discharge；Can using temperature Reach 120 DEG C, be the ideal material as filter cloth.But there is also water absorption rate larger the problems such as, influence whether the steady of filter cloth size Qualitative energy, limits the application in the industry of fine solid-liquid separation and development.The performance of nylon monofilament filter cloth also needs to further Improve.
Polyster fibre in synthetic fibers has excellent physical and chemical performance, using extensive, quickly grows, and becomes current The most chemical fibre of yield in the world, but existing ordinary polyester is hydrophobic fibre, the hygroscopicity of its fabric, hydrophilic Difference, regain is only 0.4%, and this becomes the principal element of impact terylene wearability.With the lifting of people's quality of life, take Decorations have been not only the change of color, style, it is also proposed new requirement to the quality and function of fabric.Improve dacron Hydrophilicity, so that the increasingly demand to meet people for the wearability of raising dacron, energy saving simultaneously, reduces environment Pollution, is also must concern in textile process technology.
The modified method of dacron hydrophilic has a lot, and such as corona treatment is modified, ultraviolet irradiates modification, alkali subtracts Modified method of amount, ferment treatment etc., but dacron all can not be made to reach the effect like cotton.
In recent years, the modification technology of electron beam irradiation grafting raising dacron hydrophilic performance has the glamour of uniqueness, Gradually it is valued by the people.The main thought of this technology be polymer surfaces or body phase grafting have hydrophile function monomer or Functional group, thus improve the hydrophilicity of dacron.Electron beam irradiation belongs to one of high-energy irradiation method, when having reaction Between short, little to fibre damage, percent grafting is high, the advantages of good endurance.Its principle is exactly using the ionization of radiation-initiated polymerization thing With excite, thus producing some free radicals, cause chemical reaction further, related research is a lot.This research is conventional Research foundation on by the high-power electron beam of electron accelerator, AA monomer is grafted to the surface of dacron, increase hydrophilic group Group, improves the hydrophilic of dacron, is allowed to really possess hydrophilicity specific to natural fiber.
《The hydrophilicity of irradiation grafting modified dacron fabric》Give irradiation grafting modified polyester monofilament filter cloth, equally may be used With irradiation grafting modified nylon monofilament filter cloth, to improve the problem that water absorption rate is larger, filter cloth size stability is poor.Also need to change Enter chinlon filter cloth loosely organized, elasticity is bad, resistant and resistance to elevated temperatures are poor, the problem that filter cake is not easily stripped.Also need to improve The thermostability of filter cloth, UV resistance, antistatic, intensity, toughness, wearability, antifouling, antibacterial, adsorptivity and graft modification film strong The performances such as degree.
