- conjugate fibers spun into a side-by-side type with a joint surface shape that is curved so as to envelop not only yields a yarn-dyed yarn having as high a crimp as a false twisted yarn, but also provides a temporary yarn. It is preferable because there is no residual torque peculiar to twisted yarn and the handleability of the force in the force dyeing process is facilitated.
- the crimped yarn is usually 80% by weight or less, preferably 70% by weight, as long as the object of the present invention is not impaired.
- Blended with other fibers such as wool at a content of not more than 50% by weight, more preferably not more than 50% by weight.
- Silofil, etc. entangled mixed yarn (different shrink mixed yarn with high shrink yarn) Etc.), intertwist, composite false twist (elongation difference temporary rubbing, etc.), and two-feed fluid jetting.
- one or two or more crimped yarns in the case of false twisted yarn, the false twist direction is the same direction. And may be in different directions), and the twisting (additional twisting) may be performed at 50 to 1001: 111, preferably at 50 to 300 T / m.
- the twisting may be performed at 50 to 1001: 111, preferably at 50 to 300 T / m.
- the twisting device is not particularly limited, and an Italian twisting machine, a ring twisting machine, a double twister, or the like can be used.
- the polymethylene terephthalate fiber is characterized in that the torque is not easily reduced. This is because polytrimethylene terephthalate fiber has a high thermal shrinkage, and if a twist-set is performed in a tensioned state, the amorphous portion shrinks, and the shrinkage stress causes the crystal portion to expand. Even if this crystal part is twisted and set, torque is not reduced because it is almost completely elastic. Therefore, it is presumed that only yarn with high residual torque can be obtained as a result.
- Polytrimethylene terephthalate fiber is flexible, so if a knives is made using a yarn with a high residual torque, the local concentration of torque will cause a snare (partly twisting) around the fulcrum. Phenomenon) occurred, and it became clear that there was a problem that the yarns became entangled by this snare and the yarn separation became worse.
- the present inventors have found that, in the case of polytrimethylene terephthalate fiber, if the number of twisted yarns is less than 30 OT / m, even if a skein is prepared without performing a twisting set, the yarn is formed. Since the torque is absorbed by the filaments, it is found that the torque is not concentrated locally, and a scab that hardly generates snare can be obtained.
- the twist-stopping set is performed. No problem. In such a case, it is preferable to adopt a method of performing the twist-stop setting while relaxing the yarn, since the twist-setting set of the polytrimethylene terephthalate fiber is difficult to be effective in a tension state. For example, there is a method in which a dummy cushion material made of corrugated cardboard is wound on an inner layer of a cylinder having an aluminum collar and then rewound, and a fire prevention set is performed while sufficiently relaxing the yarn.
- the winding amount may be set to such an extent that the winding form is not collapsed by setting in the bobbin winding. In order to make the set sufficiently effective, it is preferable to wind with a winding tension of 0.1cN / dtex or less.
- the processing temperature is preferably from 60 to 110 ° C, and the processing time is usually preferably from 10 to 60 minutes from the viewpoints of sufficient setting effect, crimp development, and energy efficiency.
- the crimped yarn may be parked before and after the burning of the fired yarn in order to make latent crimp visible by the yarn and increase the crimp.
- This method is effective because the crimped yarn may not be sufficiently relaxed during dyeing.
- Examples of such a device for producing a palky include a bulone manufactured by Sakamoto Reizen Co., and a continuous palky output device manufactured by Superba.
- an overfeed rate of 50 to 200% may be used, and dry heat, steam, or the like is used as a heat source for relaxation, preferably 60 to 200 °. C, and more preferably, at 90 to 190 ° C.
- the bulked yarn thus obtained has a boiling water shrinkage of 4% or less and a crimp elongation of 50% or more. This is because the yarn shrinks only slightly at the time of dyeing the cheese, and the crimp does not expand with the shrinkage, so that a yarn-dyed yarn having a high crimp elongation rate can be obtained.
- the scalpel dyeing method it may be carried out in accordance with the above-mentioned dyeing method.
- To relax to develop crimp while minimizing tension).
- the force when it is relaxed in the pretreatment, it is preferably 50 to 100 ° (:, more preferably 60 to 90 °) using a hot air drier, a casse continuous heat treatment machine or the like.
- a dry heat treatment may be performed for 5 to 30 minutes at C.
- 60 to 130 ° C., more preferably 80 to 30 ° C. using an auto crepe, steam setter, steam box, or the like.
- Steam treatment should be performed at L 10 ° C for 5 to 30 minutes, but before fixing the case to the formwork or packing the force in a bag or the like at high density and restraining the case itself When the treatment is performed, crimps may not be sufficiently developed.
- the case when the case is to be relaxed during the scouring and dyeing processes, the case must be prevented from adding tension, a rotating pack, a whirlpool dyeing machine, etc. It is preferable to perform the hot water treatment at 50 to 130 ° C. for 5 to 60 minutes.
- some jet dyeing machines have fixed pars at the top and bottom to adjust the length of force, but with such a device, fix as much as possible so that the scalp can be relaxed during processing. It is preferable to reduce the interval between pars.
- the dyeing may be performed in accordance with the above-described dyeing method. This is preferable since a dyed yarn can be obtained.
- the yarns of the present invention include, in particular, natural cellulose fibers such as cotton and hemp, regenerated cenorellose fibers such as cupra, viscose rayon, and polynoc rayon, and lyocell (directly spun cellulose fibers). Threads mixed with wool fibers such as cellulosic fibers such as wool, alpaca, mohair, angora, camel, and cashmere make effective use of the feel of cellulosic fibers and wool fibers, and their dimensions. Yarn-dyed yarn excellent in stability and stretchability is obtained, which is preferable.
- those mixed with a regenerated cellulose fiber multifilament such as cupra viscose rayon are preferable in the case of a woven or knitted fabric, since the glossiness of the regenerated cellulose fiber multifilament can be obtained. If a regenerated cellulose fiber multifilament having a boiling water shrinkage of 3 to 5% is mixed, the difference in shrinkage from the poly (trimethylene terephthalate) fiber during dyeing will increase, and the texture of the cellulose will not be lost. Is also preferred because it also easily develops.
- the spinning method and the like of the regenerated cellulose fiber are not particularly limited, and fibers produced by any method such as a Hank method, a cake method, a net process method, and a continuous spinning method may be used.
- a hank method, a cake method, a net process method or the like it is preferable to use a hank method, a cake method, a net process method or the like.
- two or more of these yarns may be combined and tangled or entangled, and depending on the purpose, a yarn containing a matting agent such as titanium oxide or various known additives may be used. .
