Description
Background technology
1. technical field
The present invention relates to the mixing cord of preparation twisting.
2. the description of association area
Dissimilar material (such as, one has high modulus and one has comparatively low modulus) usually one is used from mixing cord, for application such as such as tire enhancings.When forming plied cord, consider the modulus difference between bi-material, or in order to realize the cord response expected, usually in high-modulus strand and low modulus strand, use different twist level.Current this can not realize on cable-former, because it can not form cord in the mode identical with ring type twisting mill.Although mixing cord can be prepared on cable-former, but attainable cord limited performance is in the twisted cord of balance, that is, the performance of the wherein cord that high-modulus is identical with low modulus strand length, in this case, a kind of response is only existed for any given twist level.When the unbalanced mixture of needs, current its is prepared on ring type twisting mill.Cable-former provides huge production capacity advantage, so, consider that unbalanced mixture is more common than the twisting mixture of complete equipilibrium, preparation balance and unbalanced mixture on this type of machine may be desirably in.

Summary of the invention
The present invention relates to a kind of mixing cord, it comprises multiple strand, does not wherein consider the twisting of described strand, and at least two in described strand have the strand length do not waited, and at least one in described strand has the length than other strand long 1 to 50%.
Detailed description of the invention
So-called mixing cord refers to the cord be made up of at least two strands, and wherein at least one strand has the modulus different from other strand.Such as, strand can be para-aramid and another strand can be nylon.Described strand also can have identical composition, but has different modulus.
So-called zero plying refers to when being removed from cord by strand but not making cord loose, the twisting amount can measured in strand.So-called strand length refers to when being removed from cord by strand but not making cord loose, the length of strand.
When being combined in cabling process by two yarn strands, described strand runs through adjuster.Described adjuster can be made up of the pulley of two on a side, and described pulley is connected to two pulleys on another side by two solid shaftings.Described adjuster contributes to guaranteeing that strand enters cord twisting mill with identical speed.Fig. 1 is to mark the adjuster that 10 roughly illustrate prior art, and it comprises the pulley 11 connected by axle 12.The diameter of described pulley is all identical.Fig. 2 illustrates in general an adjuster to mark 20, and it comprises the pulley 14a being connected to pulley 14b by axle 15.Two pulley 14a on side 1 have the diameter larger than the pulley 14b on side 2, and the strand therefore running through side 1 enters cord more quickly by than the strand from side 2.This is because the pulley on both sides is connected by solid shafting and must rotate with identical speed.The larger girth (contrary with the pulley on side 2) of the pulley on side 1 creates longer path that strand reels and therefore for each rotation of pulley, carries more multi cord.Fig. 3 is the side view of Fig. 2 and the path of strand 13 around larger diameter pulley 14a is shown.Second composition strand follows the Similar Track (not shown) around small diameter pulley 14b.Therefore, do not consider the twisting of strand, at least two in described strand have the strand length do not waited.In one embodiment, the present invention uses a series of pulley size to form unbalanced mixing cord.By sending high-modulus strand and send comparatively low modulus strand above comparatively large pulley above comparatively truckle, in cord structure, high-modulus strand will be longer than other strand.The ratio that ratio between pulley size will determine between strand length.If the diameter ratio for the pulley of high-modulus strand is used for the diameter large 25% of the pulley of low modulus strand, then the former will be about 25% than the latter.
Except mate the performance of unbalanced ring type twisting mixing cord on cable-former capacity level except, also can improve the quality of cord.When forming the large twisting difference between high-modulus strand and low modulus strand on ring type twisting mill, the low modulus strand of highly twisting provides the moment of torsion of the abundant residues in cord.If use different size pulley cable-former on realize length difference, then the residual torque in this type of low modulus strand will minimize or not exist.This is by how neutral for permission cord and more hold manageable cord in the mill.
Mix cord to be made up of multiple strand, wherein there is zero twisting in strand, and at least one in strand has than other strand long 1 to 50%, or long 1 to 35%, or even grow the length of 1 to 25%.Select the different length amount between strand, with applicable particular characteristic requirement.In certain embodiments, the line density that cord has 500 to 5000 DENIER is mixed.In certain embodiments, the line density that cord has 1000 to 3500 DENIER is mixed.Mixing cord can be made up of polymer strand, and described polymer strand is meta-aramid, para-aramid, polyazole, nylon, polyester, PEN (PEN), artificial silk, polypropylene, ultra-high molecular weight polyethylene (UHMW-PE) or carbon such as.Suitable polyazole is poly-
diazole, such as with trade name Arselon from OJSC Svetlogorsk Khimvolokno(Svetlogorsk, Belarus) buy.Mixing cord also can be made up of metal strands.
Mixing cord can comprise the single strand of high modulus material and the single strand of low-modulus material, and such as at least one para-aramid strand and at least one nylon strand, wherein the strand of shorter length is nylon.Mixing cord even can comprise at least one para-aramid strand and at least one meta-aramid strand, and wherein the strand of shorter length is meta-aramid.
In a preferred embodiment, described strand comprises thread yarn, and described thread yarn can be that continuous print, part are discontinuous or discontinuous, and this type of term is known in textile field.The example of the discontinuous yarn of part is crush cutting yarn.The example of discontinuous yarn is for prescinding yarn.
In one embodiment of the invention, para-aramid strand, than meta-aramid strand long 2 to 7%, preferably grows 3 to 6%, or more preferably grows 4 to 5%.The mixing cord being shaped to this structure of woven or knit goods is particularly useful for standing the assembly of burst pressure test under low temperature such as room temperature and the testing fatigue at high temperature such as 175 DEG C.The example of this class component is turbocharger hose, and wherein cord provides and strengthens the structure of elastomeric material.Similar application can be present in the application of other mechanical rubber good, such as conveyer belt and tire.In other embodiments, para-aramid strand can than poly-
diazole strand long 3 to 5%, or poly-
diazole strand can than meta-aramid strand long 1 to 10%.
Strand can have identical or different twisting.In certain embodiments, strand has zero twisting.
Pulley is applicable to installs any cable-former, such as can purchased from Oerlikon Saurer(Charlotte, NC) or Verdol(Valence, France) or Aalidhra Textile Engineers Ltd.(Surat, India) those.
In one embodiment, the invention still further relates to the method that the cord with the predetermined twist and composition strand length is provided, said method comprising the steps of:
I () determines cord twist factor and the composition strand length of expectation,
(ii) composition forming strand number and each strand is determined,
(iii) cable-former is provided,
(iv) pulley of appropriate size selected by the adjuster for cable-former, makes the pulley on side 1 be greater than pulley on side 2, to provide the composition strand length of expectation in cord,
V the twist level of the mixing cord of expectation is set in described cable-former by (),
(vi) by described strand feed in cable-former, and
(vii) preparation has the twist factor of expectation and the cable of composition strand length.
Another embodiment relates to the method providing the mixing cord with predetermined twisting and composition strand length, and described method causes forcing length difference to carry out by adjustment of tonicity, and described length difference realization is above summarizes target, and the size of its middle pulley increases.This embodiment comprises the following steps:
I () determines cord twist factor and the composition strand length of expectation,
