Abstract
The polypropylene BCF carpet yarn with lodging resistance is spun out from the mixture of anti-lodging mother particles and polypropylene chips. Because polyester compound and antistatic agent are added to mother particles, so the fibre has high elastic modulus, antistatic nature and spinnability. The technology is simple.
Description
The invention belongs to the manufacture method of improving the polypropylene fibre carpet yarn with polyester.Specifically, be the method for preparing a kind of " distortion " stable BCF carpet yarn with petchem and antistatic additive PR-86 and polypropene blended spinning.
At present, domestic and international polypropylene BCF (varicosity continuous filament yarn) carpet of producing, pliable and tough, warming, comfortable owing to it, easily preserve and be subjected to the user and welcome, but this carpet not with the animal and plant industrialization mass production of contending over raw materials, its output far surpasses the output of natural material carpet.Though the polypropylene BCF carpet is well received, its performance is anxious to be waited to improve, and the modulus and the elasticity that improve and improve polypropylene BCF carpet yarn are one.Current polypropylene carpet, the upright fibres rigidity is not good, very easily lodging, and after pressing the volt long period, can not recover former erectility, become permanent lodging.Solve its lodging performance and still do not have effective way at present." synthetic fiber " fifth phase in 1985, close in " application of polypropylene fibre " literary composition of writing at fine scientific and technological information station and speak of Zhejiang Province textile of chemical fibre Science Institute and Shandong Province, for solving " shortcoming of pp carpet resilience difference; the producer that has selects the square short pile structure of 1/8 needle gage for use; can reduce the pile lodging and flatten, thereby can obtain apparent preferably resilience ".Another piece of writing report " synthetic fiber industry " third phase in 1989, domestic news in brief " the high elasticity polypropylene fibre is studied by technical appraisement ", introduced Shandong synthetic fiber research institute through development, can make the extension at break of polypropylene fibre〉250%, 50% and 100%, the specified elongation elasticity recovery rate is respectively 96% and 87%, but does not but report any technology contents.
The objective of the invention is to avoid above-mentioned shortcoming and provide a kind of add that petchem and PR-86 mix with polypropylene and the method for making a kind of BCF carpet yarn resistant to lodging.
The present invention can realize with following measure, for resistant to lodging, mainly be on the basis that keeps former performance, increase the modulus and the elasticity of polypropylene fibre, its outstanding feature is an elastic modelling quantity, and the elastic modelling quantity of existing polypropylene BCF carpet yarn is about 27 lis of newton/dtexs.For increasing elastic modelling quantity, we mix a certain amount of polyester in polypropylene chip, and carrying out the polypropene blended spinning fibre of co-blended spinning on the common spinning machine of single screw rod is island type structure, thereby has improved its elasticity.Again: promptly improve spinnability in order to improve the spinning properties that adds behind the polyester, solving the shortcoming of the spinnability difference that causes the petchem addition more, in the spinning batching, adding antistatic additive PR-86(is made up of the macrogol ester class, see Chinese patent 86106302.2), can make and reduce the waste silk rate in the polypropylene BCF fibre spinning largely, and further improve the modulus and the elasticity of fiber, make carpet have antistatic property simultaneously.
In order to satisfy user's different requirements, the invention provides two kinds of prescriptions, prescription one is that elastic modelling quantity is higher, the prescription that lodging tolerance is strong; Prescription two is more lower slightly than prescription one elastic modelling quantity, but fiber is after the short time is pressed volt, and elastic recovery capability is strong.Also can use with by two kinds of prescription gained silks, performance is between two kinds of performance formulas.
The present invention can also adopt following measure to realize, for making the polypropylene BCF carpet yarn of high-modulus, polyester resin that is added and antistatic additive will be made master batch resistant to lodging in advance, and master batch is made up of virgin pp section, petchem, antistatic additive PR-86.Wherein, the petchem structure is:
Wherein: x=2～7; Y=70～140.Addition is: 55%～90%(weight ratio, down together.); The polypropylene chip addition is: 0.5%～45%; The PR-86 addition is: 0.5～20%.For actual prescription, prescription one: petchem polyester A wherein:
Wherein: m=2～3; N=70～140; Prescription two: polyester B wherein:
Wherein: p=4～7; Q=75～135.
Above-mentioned master batch resistant to lodging and polypropylene chip are carried out co-blended spinning get final product on common single extruder type spinning machine, the addition of its master batch resistant to lodging is: 1～7.5%.It is few to go in the weight range addition in certain, and then the elastic modelling quantity increasing degree of polypropylene BCF carpet yarn is little, and the elastic modelling quantity increasing degree is big at most for addition.
Embodiments of the invention are as follows:
Embodiment one: adopt formula of master batch one resistant to lodging, polyester A uses:
Addition: 80%, polypropylene chip addition: 1%, PR-86 addition: 19%, master batch by 3% with polypropylene chip 97% blend, use the common screw spinning, the initial modulus of gained BCF carpet yarn is 38.7 lis of newton/dtexs, spins the initial modulus of virgin pp fiber down than identical spinning condition: 28.8 lis of newton/dtexs, improved 34.4%.
Embodiment two: adopt formula of master batch two resistant to lodging, polyester B uses:
Addition is: 99%, polypropylene chip addition: 0.5%, antistatic additive PR-86 adds: 0.5%, during spinning master batch by 5% with polypropylene chip 95% blend, use the common screw spinning, gained polypropylene BCF carpet yarn product, its initial modulus are determined as 35 lis of newton/dtexs, the 28.8 lis of newton/dtexs of initial modulus that spin the virgin pp fiber than identical spinning condition have down improved 21.5%, and rebound degree of its 5% fixed elongation can bring up to 97% by former 93%.
Virgin pp section addition is during spinning: 82.5%～99%, and all the other are master batch.Prescription one adds with prescription two blend in certain proportion, and the elastic mould value of product is between the high elastic modulus of prescription one and two the minimum elastic modelling quantity of filling a prescription, therefore can give the master batch additional proportion of prescription estimated one and prescription two by the design data of customer requirements or product.
The present invention has following advantage compared to existing technology:
1, can improve the initial modulus of polypropylene BCF carpet yarn, the amplitude of raising is 40～49%, because the raising of elastic modelling quantity, the ability of its resistance to deformation strengthens, product is difficult for lodging.
2, when improving elastic modelling quantity, also can improve the rebound degree of fiber, particularly fill a prescription two, rebound degree of its 5% fixed elongation can be increased to 98% from 90%, and this recovery to angle and curved deformation or short time lodging is very favourable.
3, in master batch, dose the PR-86 antistatic additive, regulated the rheological property of melt, thus not only improved the antistatic behaviour of product, and the spinnability of polypropylene section is improved greatly, and having reduced the waste silk rate, it is plentiful that appearance of fabrics also seems.
4, because manufacturing, the spinning moulding of master batch all used commonsense method, process conditions it goes without doing big change, and good spinnability, therefore good in economic efficiency, easy and simple to handle, be easy to promote.
