Generally, polyamide fiber taffeta is dyed using jitzger dyeing machines, beam dyeing machines, pad roll dyeing machines, and continuous dyeing machines, but productivity is low, dyeing defects tend to occur, and dyeing loss and energy loss are large. It has the following disadvantages. That is, in dyeing methods using conventional dyeing machines, it is technically impossible to completely solve these drawbacks caused by the dyeing machine itself. In the case of Jitzger dyeing machines, the concentration distribution of the dye in the dye liquor, the temperature distribution of the dye liquor,
Also, defects such as ending and resting are very likely to occur due to the uneven adhesion of the dye solution to the polyamide fiber taffeta. In order to overcome these drawbacks, the general method is to slow down the temperature rise rate, add an excessive amount of slowing agent, or adjust the pH of the dye solution to the alkaline side, and then gradually add acid to suppress the dyeing rate. However, these methods cannot completely cover dyeing defects.

る。 In the case of a beam dyeing machine, the dye liquid is injected by a jet pump and penetrates the rolled up polyamide fiber taffeta, so with high-density taffeta, the amount of dyeing liquid must be significantly reduced. It is not possible to penetrate the dye solution uniformly, and even in the case of low density, it is difficult to penetrate the dye solution uniformly through polyamide fiber taffeta rolled up in the form of a spread cloth. That is, since the dye liquor penetrates through areas where the pressure distribution is small, dyeing defects such as smeared edges and smeared edges are likely to occur, and energy loss is also large because the bath ratio is large. In the case of a pad roll dyeing machine, the spread taffeta is immersed in a dye solution, squeezed with a mangle, and then passed through a heater to prevent dye transfer and preheat.
After rolling it into a roll, slowly rotate it while maintaining a predetermined temperature and humidity to fix the dye. On the other hand, in a continuous dyeing machine, a spread-out taffeta is dipped in a dye solution and squeezed with a mangle, and then the dye is fixed by dry heat treatment, moist heat treatment, acid shock, etc.

る。 However, in both pad roll dyeing machines and continuous dyeing machines, it is difficult to apply dye uniformly due to the influence of the pressure distribution of the mangle, and therefore uniform dyeing is difficult. Furthermore, since the dye utilization efficiency is low, the dye loss is also large, and it has the disadvantage that it cannot be applied to dark colors. Recently, attempts have been made to dye polyamide fiber taffeta using liquid jet dyeing equipment in order to cover these dyeing defects, reduce dye loss, save energy, and improve productivity. Since the fabric is dyed in a uniform manner, the occurrence of wrinkles is unavoidable, and the wrinkles that occur in this case are treated as dye wrinkles and cannot be corrected in subsequent steps. In general, when dyeing polyamide fiber taffeta, the generation of wrinkles during dyeing is considered to be a fatal flaw, and the most important point in determining the quality of the dyeing is how well the dyeing can be done without wrinkles. Among polyamide fiber fabrics, knitted fabrics, and among woven fabrics, special fabrics such as satin and twill fabrics, fabrics using strong twist yarns, and fabrics using processed yarns are generally jet dyed because dyeing wrinkles do not occur. equipment is applied.

繊維長差％を表わす）。 0 < Dyeing wrinkles occur because it is rubbed or squeezed too hard. The present inventors focused on the fact that the occurrence of dye wrinkles is particularly affected by the weft yarn, and as a result of intensive study, we found that it is possible to improve dye wrinkles by giving fiber length differences to the weft yarn and reducing the shrinkage rate. found that it is effective. The polyamide fiber used in the present invention is polycapramide (nylon 6) or/and polyhexamethylene adipamide (nylon 6).
6), both the high-shrinkage fibers and the low-shrinkage fibers constituting the mixed yarn are made of the same material, or a mixed yarn that is a combination of different materials. In order to impart fiber length differences, both the low shrinkage fibers and, if necessary, the high shrinkage fibers, can be heat-treated at the yarn stage using the method described in JP-A-52-91960, or different deniers can be obtained using a simultaneous spinning method. It can also be obtained by blending fibers. The method of blending fibers may be a simultaneous spinning method, a pulling method, an air entangling method, etc. depending on the type of material and the level of fiber length difference. The fiber length difference of the taffeta weft yarns according to the present invention is expressed by heat treatment before dyeing and/or heat treatment during dyeing. is preferably used, but there is no particular limitation as long as it is a heat treatment such as moist heat that produces a difference in fiber length. The heat treatment temperature is 60~ for hot water.
100℃, 160-210℃ for dry heat, 100-150 for wet heat
℃ is preferred, more preferably 90~90℃ in hot water
100℃, dry heat 180-200℃, moist heat 110-140
It is best to process at ℃. The heat treatment produces a difference in fiber length and at the same time satisfies the shrinkage rate of taffeta at the dyeing temperature expressed by equation (2). If the fiber length difference exceeds 14%, it is not preferable because defects such as uneven graining occur. Japanese Patent Publication No. 58-36285
Although this publication describes a polyamide fiber fabric with a fiber length difference of 0%, fabrics with no fiber length difference are undesirable because dyeing wrinkles occur. The polyamide fiber yarn used for the weft yarn of the present invention is not a crimped yarn like a processed yarn, but a mixed fiber yarn using a non-crimped yarn. Furthermore, in order to improve dye wrinkles, it is important to reduce the shrinkage rate of taffeta in the horizontal direction under the dyeing temperature, which is closely related to the fiber length difference. The dyeing temperature is preferably as low as possible in order to reduce the shrinkage of the taffeta in the horizontal direction, but from the viewpoint of dyeability, it is necessary to keep the dyeing temperature high, and 60 to 110°C is preferable. The shrinkage rate (Y%) of taffeta in the weft direction is expressed by the following formula: 0Y1/2X+4 (X represents the fiber length difference % that occurs in the weft yarn of taffeta due to heat treatment before dyeing and/or heat treatment during dyeing) .

くすることが染めシワの面から重要である。It is important that the fiber length difference (X%) be within the range of 1% or more. If it exceeds the above range, dye wrinkles will occur, which is undesirable.
Next, as shown in equation (2), the shrinkage rate (Y%) of taffeta in the horizontal direction is closely related to the aforementioned fiber length difference (X%) and dyeing temperature. From equation (2), if the fiber length difference (X%) is 10%, the shrinkage rate (Y%) in the horizontal direction of taffeta should be within 9%, but if the fiber length difference (X%) is 2%, For dyed products, it is necessary to suppress the shrinkage rate (Y%) to within 5%. Therefore, the smaller the fiber length difference (X%), the smaller the shrinkage rate (Y%) is from the viewpoint of dye wrinkles. is important.

うに定義する。 To adjust the horizontal shrinkage rate (Y%) of taffeta, first set the dyeing temperature, then (2)
Heat treatment conditions are set that satisfy the formula and provide the shrinkage rate (Y%). The specific heat treatment temperature is the temperature range that causes the fiber length difference (X%) shown above to occur, but for fibers with a small fiber length difference (X%), heat treatment at a higher temperature is recommended to reduce shrinkage. This is preferable from the viewpoint of suppressing the ratio (Y%). Tokukai Akira
No. 52-91960 describes the dyeing of polyamide mixed yarn taffeta with fiber length differences using a winch, but even if this taffeta is dyed with a jet dyeing machine, the shrinkage rate of the taffeta in the horizontal direction is large. ,
In most cases, dye wrinkles occur, which is undesirable.
Here, the fiber length difference (%) and shrinkage rate (%) are defined as follows.

る。 Fiber length difference = l L - l H / l H × 100 (%) (However, l L and l H are the weft yarns of taffeta after heat treatment before dyeing and/or heat treatment at the corresponding temperature during dyeing. Represents the yarn length of the low shrinkage fiber and high shrinkage fiber when decomposed.) Shrinkage rate = l 0 - l/l 0 × 100 (%) (where l is the length of the fiber subjected to heat treatment at a temperature equivalent to the dyeing temperature. The length of the taffeta in the horizontal direction after heat treatment, and l0 represents the length of the taffeta in the horizontal direction before heat treatment.) The liquid jet dyeing apparatus of the present invention is of a type in which the fabric is transferred using a nozzle and a reel. There are two main types: , and those that transport the fabric using only a nozzle, but any of these methods can be applied. Further, the operating conditions of the jet dyeing apparatus such as nozzle pressure, reel speed, cloth speed, etc. can be appropriately selected depending on the basis weight of the taffeta to be added, weave density, amount of input, dye concentration, etc.
