［従来の技術］

高メツシュ織物化が要求されている。[Prior Art] Polyester monofilament yarn has been widely used as a screen gauze material because it has many excellent properties that other fiber materials do not have, such as dimensional stability and elastic recovery. In addition, with the recent progress in electronics and the increasing quality of printed materials, screen gauze is increasingly required to be woven with a high mesh.

紗の品位の低下などの問題点があった。In other words, polyester monofilament yarn has problems such as white powder and scum falling off during the weaving process, warp breakage due to clogging of the reed, warp unevenness, and deterioration of the quality of the screen gauze due to the weaving of white powder scum.

うに種々検討が試みられている。For information on suppressing the generation of white powder and scum, which has been a problem in the past, please refer to JP-A-Sho! 1s-16948 publication or special
Various studies have been attempted, as proposed in 1982-169540.
［発明が解決しようとする問題点］

細工（曲線をわがぼる方法が常套手段として採用されて
いる。[Problems to be Solved by the Invention] Generally, in order to improve the weavability (including shedding of white powder and scum) of general polyester yarns, including those used for screen gauze,
Lower the ratio of the tension to the elongation of the yarn, that is, lower the tension
Craftsmanship (the method of making curved lines is commonly used).
しかしながら、この手法はスクリーン紗用途には適用で
きない。なぜならば、単純に張力・伸長曲線をねかぜた
だけでは、スクリーン紗の張力・伸長曲線もねてしまい
、ポリエステルスクリーン紗の特徴の１つである寸法安
定性を欠くためである。However, this method cannot be applied to screen gauze applications. This is because if the tension/elongation curve of the screen gauze is simply changed, the tension/elongation curve of the screen gauze will also be changed, resulting in a lack of dimensional stability, which is one of the characteristics of polyester screen gauze.
スクリーン紗の製織はオープニングエリア（経糸と緯糸

糸はｍ機上の綜絖、筬などで繰返し強い擦過を受ける。Screen gauze weaving requires precision and uniformity in the opening area (the voids made up of warp and weft yarns), so it is woven under conditions of much higher tension than the weaving of general textiles such as clothing. be done. , and the weave density is also 100
Since the warp yarns are high (500 yarns/inch, 7 inches), the warp yarns are repeatedly subjected to strong abrasion by the heddles, reeds, etc. on the machine.

ため、綜絖、筬は白粉、スカムを取除くため頻繁に洗浄
が必要になってくる。As a result, the thread surfaces of the warp threads are destroyed, scraped off, and mixed with the finishing oil that has been previously attached to the thread surfaces, producing a gummy substance generally called white powder or scum. When this white powder and scum accumulates on the healds and scum, it causes poor shedding and warp thread breakage. In addition, serious problems such as warp defects due to clogging of the reed and deterioration of quality due to white powder and scum being woven will occur. For this reason, the healds and reeds need to be washed frequently to remove white powder and scum.

残る。From the perspective of suppressing white powder and scum during weaving,
The lower the strength is when the tension/elongation curve of the raw yarn corresponds to the thread tension during weaving screen gauze, that is, when the elongation is 10%, the more remarkable the effect is seen in suppressing the generation of white powder and scum. However, the screen gauze after finishing heat treatment is
Compared to conventional thread-based products, the tension and elongation curves are considerably smoother, and the accuracy of the opening area and
There is a tendency for quality such as uniformity to be low, and problems remain in practical use.

するという知見を得たのである。Therefore, as a result of analyzing screen gauze subjected to finish heat treatment, the present inventors found that the tension/elongation curve and quality of screen gauze subjected to finish heat treatment are related to the shrinkage rate due to dry heat treatment maintained by the raw yarn. We found that there is a significant and close relationship, and upon further investigation, we found that the lower the shrinkage rate of the raw yarn due to dry heat treatment, the higher the tension/elongation curve of screen gauze that has been subjected to finishing heat treatment. They found that the accuracy and uniformity of the opening area can be improved significantly.

% strength is in the range of 1.5 to 3.2 g/d, and the breaking 1gi strength is 4.0 (1/d or more and at 200℃
This can be achieved by using polyester monofilament yarn for screen gauze, which has a shrinkage rate of 12% or less in a 15-minute treatment.
以下、本発明について詳細に説明する。The present invention will be explained in detail below.
本発明においては、製織時の白粉、スカムの発生を抑制

張力・伸長曲線で、伸びが１０％の時の強度を低くすれ

長曲線において、伸びが１０％の時の強度を１．５〜３
．２ ｇ／ｄの範囲とし、破断強度を４．０ ｇ／ｄ以
上にすることが必要である。In the present invention, from the viewpoint of suppressing the generation of white powder and scum during weaving, the lower the strength at 10% elongation in the tension/elongation curve of the monofilament yarn of the raw yarn, the lower the white powder. Although a remarkable effect is seen in suppressing the generation of scum, on the other hand, the breaking strength of the screen gauze after finishing heat treatment is also lowered, so the monofilament yarn has a strength of 1.0% at an elongation of 10% in the tension/elongation curve. 5-3
．． 2 g/d, and the breaking strength must be 4.0 g/d or more.
つまり、モノフィラメント糸の伸びが１０９６の時の強

０％の時の強度が３．２ｇ／ｄを越えると、白粉、スカ
ムの発生の抑制効果が小さくなる。In other words, when the elongation of the monofilament yarn is 1096, the strength is less than 1.5 g/d, or the breaking strength is 4, Og/d.
If it is less than d, the breaking strength of the screen gauze after finishing heat treatment is too low, which is a practical problem. On the other hand, the elongation is 1
If the strength at 0% exceeds 3.2 g/d, the effect of suppressing the generation of white powder and scum will be reduced.
また、モノフィラメント糸の乾熱処理における収縮率は
、ポリエステルモノフィラメン１〜糸の、２００℃１５
分の乾熱処理にお（〕る収縮率を１２％以下とする必要
がある。前記収縮率が１２％を越えると、オープニング
の正確性が欠けるという欠点がある。In addition, the shrinkage rate in dry heat treatment of monofilament yarn is 200℃ 15 for polyester monofilament 1 to yarn.
It is necessary to keep the shrinkage rate during the dry heat treatment () to 12% or less. If the shrinkage rate exceeds 12%, there is a drawback that opening accuracy is lacking.
なお、モノフィラメント糸の乾熱処理における収縮率は

ことか好ましい。As mentioned above, the lower the shrinkage rate in the dry heat treatment of monofilament yarn, the better the screen gauze performance.
It is preferable that the shrinkage rate in dry heat treatment at 00° C. for 15 minutes is 1% or more.

It may be a copolymer of 1 to 15 mol% of a third component such as phthalic acid, polyethylene oxide, polypropylene oquinide, sodium m-phenolsulfonate, etc., and may also be used for the purpose of matting effect or improving thread-spinning property. , even those containing 0.1 to 5% of commonly used titanium oxide are effective.
