In the present invention, in order to make arrangement (comprising dyeing processing) no matter how its knitting technology weave of the raschel of state all is soft feel, become the knitted fabric that does not in use produce the rebound retardation shortcoming, the row number that focuses on being set as the product knitted fabric is 100-200 row/2.54cm, be preferably 120-170 row/2.54cm, and the long-pending of row number/2.54cm and coil wale number/2.54cm is 4000-8000.
Even knitted fabric of the present invention uses the polytrimethylene-terephthalate fiber with soft feel to organize as ground, when improving knitted fabric density, the feel hardening, material has distinctive extensibility, so weight per unit area and thickness increase.As reduce the density of knitted fabric, become have soft feel, light and thin knitted fabric, but the restraining force to elastomer that the more little then polytrimethylene-terephthalate fiber of density forms descends the rebound retardation shortcoming apparition that knitted fabric produces.The row number of knitted fabric being set in above-mentioned scope, and the long-pending of row number and coil wale number is set in the above-mentioned scope, is the stretchable raschel warp knit fabric institute conditio sune qua non that obtains not produce the rebound retardation shortcoming.
The density of warp-wise is during less than 100 rows/2.54cm, the surperficial grade of raschel (order face) variation, and the rupture strength of tricot descends greatly.When the density of warp-wise during greater than 200 rows/2.54cm, though order face and rupture strength are no problem, order is paid and is become excessive, knitted fabric thickening, feel hardening.
In stretchable raschel warp knit fabric of the present invention, the density of warp-wise is very important, simultaneously, the density of tricot is also very important, row number/2.54cm and coil wale number/2.54cm long-pending (to call long-pending density in the following text) is that knitted fabric density is that 4000-8000 is very important, better during for 4500-7000, then more favourable during for 5000-6500., then too small as knitting density as the density of the tricot of feel less than 4000, surperficial grade variation, and the tissue dislocation easily takes place, and producing the rebound retardation shortcoming, it is minimum that rupture strength also becomes.On the other hand, when knitted fabric density surpassed 8000, rupture strength was enough big, does not also produce the rebound retardation shortcoming, but the feel hardening for example becomes the knitted fabric that is unsuitable for the tight underwear purposes.
Therefore, need to set the grey cloth amount of the contraction of having considered knitted fabric etc., what make the row number of stretchable raschel warp knit fabric and coil wale number long-pendingly satisfies the afore mentioned rules condition.
The braiding of stretchable raschel warp knit fabric does not limit the kind and the plane No. of Raschel looms especially, but is that the Raschel looms of the plane No. of 24-32 root/2.54cm specification weaves by having 48-64 root/5.08cm preferably.
In the method for carrying out the such Fabric Design of the present invention, need make knitting coil (ラ Application Na one) length more, and make the row number on the machine little than the occasion of the mixed knitting fabric of nylon fiber or polyethylene terephthalate and elastomer with silk.Raschel to woven retractility is suitable for concise, in the preboarding operation after concise during tentering, carry out the tension force setting, it is in the density range of the present invention, and row number on the loop length of necessary setting polytrimethylene-terephthalate fiber and elastomer and the machine, with arrangement be shaped to dye after knitted fabric width and the substantially identical density of length, obtain the knitting density of regulation.The setting condition can be used known 150-200 ℃, the scope of 30-60 second, but preferably during preboarding about 190 ℃, about 170 ℃, like this, setting is good during the arrangement setting, the dyeing firmness is also no problem.The dyeing of knitted fabric is preferably used stretchable raschel warp knit fabric is applied the big liquid-flow dyeing machine of rubbing action effect.
Below, illustrate knitted fabric of the present invention by the braiding of 6 row warp sateen nets.At first, set the row number on the machine less, preferably be set at 65-85 row/2.54cm, under suitable knitting tension, carry out the braiding of grey cloth, say in more detail, the loop length 1250-1350mm/ lacquer (1 lacquer is the required filament lengths of per 480 rows) of preceding silk makes up with the loop length 120-165mm/ lacquer of back of the body silk, and, before loop length long-pending of loop length and back of the body silk of silk be in more than 150000 in the scope below 215000, when weaving under such condition, the density of line coil improves or the density raising of knitted fabric is easy to carry out.Current silk and the loop length of back of the body silk are amassed 150000 when following, easily increase line density or knitted fabric density, the finally feel hardening of grey cloth, degree of the stretching decline of finished product knitted fabric.In addition, when this amasss 215000 when above, it is low that knitting tension became, and the tissue dislocation becomes big in the grey cloth stage, produces the rebound retardation shortcoming of finished product grey cloth etc., can not obtain good grey cloth.In the occasion of arrangement that grey cloth is dyeed, the tentering density of the preboarding operation after concise for example is set at 3500-6000 when representing with long-pending density, carry out preboarding under this setting, the long-pending density of the setting of arrangement after dyeing setting can be put in order substantially should length (state that keeps the row number after the dyeing), width should be arranged (state that keeps the coil wale number after the dyeing).As the design of the knitted fabric carrying out, even can obtain also no problem tricot aspect contractions such as the wash shrinkage or the contraction of plating.As the setting condition, can be 150-200 ℃ temperature conditions scope, be about 190 ℃ during preboarding preferably, during the arrangement setting is about 170 ℃, formalize under such condition, shape stability is good, can obtain also no problem tricot aspect the dyeing firmness.
By making terephthalic acids or its functional deriv and trimethylene glycol or its functional derivatives combination under the state that exists at catalyst and the appropriate reaction conditions, the polytrimethylene-terephthalate who constitutes the used polytrimethylene-terephthalate fiber of Stretchable raschel knitted fabric of the present invention is synthesized.In this building-up process, also can add suitable the 3rd composition more than a kind or 2 kinds, obtain polyester copolymerization, or make respectively polyester beyond the polytrimethylene-terephthalate such as polyethylene terephthalate, nylon, and the polytrimethylene-terephthalate after, mix or fiber that composite spinning (sheath core, wait side by side) obtains is also contained among the polytrimethylene-terephthalate fiber.
As the 3rd composition in the polymerization that makes an addition to the polytrimethylene-terephthalate, can list binary aliphatic hydroxy acid (ethanedioic acid, adipic acid etc.), alicyclic dihydroxy acid (cyclohexane dihydroxy acid etc.), aromatic series dihydroxy acid (isophthalic acid, ソ ジ ゥ system ス Le ホ ィ ソ Off Le acid etc.), aliphatic ethylene glycol (ethylene glycol, 1, the 2-propylene glycol, 1,4-butanediol etc.), alicyclic ethylene glycol (cyclohexanedimethanol etc.), comprise aromatic aliphatic ethylene glycol (1,4-two (beta-hydroxy ethyoxyl) benzene etc.), PTMEG (polyethylene glycol, polypropylene glycol etc.), aliphatic hydroxyl carbonic acid (ω-hydroxycaproic acid etc.), aromatic hydroxyl carbonic acid (P-Para Hydroxy Benzoic Acid etc.) etc.The compound (benzoic acid etc. or glycerine etc.) that also can comprise in addition, the ester formation property functional group that has more than 1 or 3 in the substantial wire scope of condensate.During spinning, also can add antioxidants, fire retardant, the agent of system electricity, pigment, fluorescent bleaches, infrared absorbent, defoamers such as easy lubrication prescription, hindered phenol derivative such as the agent of crystallizations such as ultra-violet absorber, talcum such as stabilizing agents such as delustering agent, phosphoric acid, hydroxyl phenol derivative nuclear, ァ エ ロ ジ Le such as titanium dioxide the polytrimethylene-terephthalate.
