For example, there is a method using an island-in-the-sea composite fiber as shown in Japanese Patent Application Laid-Open No. 56-63071. However, in this case, the total cross-sectional area of the fibers decreases due to the sea removal treatment, so that it is not always possible to obtain a fabric with a sufficiently high density.

法にある。(Structure of the Invention) The present invention provides that the fineness of each single yarn after division is
Splitable composite fibers obtained by spinning polyester and polyamide in the range of 0.001 to 0.8 denier into a laminate are woven and knitted, and the woven or knitted fabric is woven with an aqueous alkaline solution before being dyed and before being split. The present invention provides a method for producing an ultrafine fiber woven or knitted fabric, which comprises the steps of:

不適当である。 The single yarn fineness used in the present invention is from 0.001 to
Any known split conjugate fiber that produces ultrafine fibers of 0.8 denier can be used. Examples of these include the one disclosed in JP-A-51-70366, in which at least four constituent parts made of polyester and constituent parts made of polyamide are arranged adjacent to each other in an annular manner, and in which fibers are There are hollow split-type conjugate fibers that extend in the longitudinal direction and constitute a tubular body as a whole, and split-type conjugate fibers disclosed in U.S. Pat. If the single yarn fineness after division is less than 0.001, the mechanical performance such as fiber strength is not practical, and if the single yarn fineness after division exceeds 0.8, the air permeability will be high.
It is unsuitable for woven or knitted fabrics using ultrafine fibers as in the present invention.

ものが好適である。 In the present invention, first, a woven or knitted fabric is created using a plurality of split-type composite fibers as described above. In order to create a high-density woven or knitted fabric, a plain weave is preferable as the woven fabric, and a cover flap for the warp and weft is used. Examples of knitted fabrics include warp knitted fabrics, weft knitted fabrics, circular knitted fabrics, etc., and examples of knitted fabrics include warp knitted fabrics, weft knitted fabrics, and circular knitted fabrics. per square inch
A high density of 1,500 to 4,000, preferably 2,000 to 3,500 is suitable.
本発明においては前記の如くして得られた織編
物は、分割型複合繊維を用いた織編物に通常行な
われる分割処理、精練、染色に先立つてアルカリ
水溶液で処理される。 In the present invention, the woven or knitted fabric obtained as described above is treated with an alkaline aqueous solution prior to the dividing treatment, scouring, and dyeing that are usually performed on woven or knitted fabrics using splittable conjugate fibers.
アルカリの濃度は0.3〜5wt％、処理温度は室温
から沸点の間で適宜選択し得るが、好ましくは、
織編物の減量率を0.1〜５％になるように条件を
設定する。 The concentration of alkali can be selected from 0.3 to 5 wt%, and the treatment temperature can be selected appropriately between room temperature and boiling point, but preferably,
Conditions are set so that the weight loss rate of the woven or knitted material is 0.1 to 5%.

ある。 If the weight loss rate is less than 0.1%, it is not preferable because the dyeing spots, which are thought to be caused by variations in the composite fiber filament, are not sufficiently resolved. Although it is possible to treat the material so that the weight loss rate is 5% or more, it is insufficient for eliminating staining spots and is uneconomical.
また、アルカリ処理と同時に収縮が起るように
アルカリ処理の温度を70℃以上で行うこともでき
る。 Further, the alkali treatment can be carried out at a temperature of 70° C. or higher so that shrinkage occurs at the same time as the alkali treatment.

ましい。 The woven or knitted fabric treated with an alkaline aqueous solution can also be subjected to a separate shrinkage treatment. The shrinkage method can be carried out by any thermal means, and the shrinkage rate is preferably 40% or more in terms of fabric area compared to before the alkali treatment.

温度で織編物を処理する。 Specific examples of phenylphenols include O-phenylphenol, m-phenylphenol, and p-phenylphenol, which are treated with a 0.15wt% aqueous emulsion at a temperature of 40°C or lower, preferably 0.2%. Process the woven fabric at a concentration of ~3.0% by weight and at a temperature of 10-35°C.

なる。 Phenylphenols are generally known to have a shrinking effect on polyester fibers and polyamide fibers, but within the above concentration and temperature range, the shrinkage of polyester is very small, but the shrinkage of nylon is very large. Under these conditions, when split composite fibers made of polyester and polyamide are processed, strain is created between the two components due to the difference in shrinkage rate, which can lead to mechanical or thermal effects during the subsequent scouring and dyeing processes. As a result, it becomes susceptible to splitting and contraction.
処理方法としては、織編物を膨潤剤含有液中に
所定温度で所定時間浸漬する方法、あるいは該織

間は１〜60分が適当である。 In the former case, it is preferable to use a liquid that is 5 times or more the weight of the woven or knitted fabric, and in the latter case, it is preferable to impregnate the woven or knitted fabric with a liquid that is 70% or more of the weight of the woven or knitted fabric. A suitable treatment time is 1 to 60 minutes.

柔軟で優れた感触を有するものである。 In the method of the present invention, when manufacturing a high-density woven or knitted fabric using splittable composite fibers that generate ultrafine fibers,
The conventional method of treating with a swelling agent has improved the inability to eliminate dyeing spots on fabrics due to differences in yarn spindles, and the present invention involves treating woven and knitted fabrics with an alkaline aqueous solution prior to dyeing and dividing them. As a result, the dyeing spots have been greatly improved, and the range of uses has been greatly expanded, such as making it possible to use warp yarns that could not be used due to dyeing spots. Furthermore, according to the method of the present invention, a very high-density woven or knitted fabric can be obtained, and in conjunction with the use of ultra-fine woven or knitted fabric, the woven or knitted fabric has a low air permeability of 0.5 cc/cm 2 /sec or less. It has a soft texture and an excellent feel.
