本発明は澱粉−ポリビニルアルコール（以下ＰＶＡと略
す。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to starch-polyvinyl alcohol (hereinafter abbreviated as PVA).
）グラフト共重合体を用いた繊維用糊剤に関する。) A sizing agent for fibers using a graft copolymer.
従来、繊維用糊剤として澱粉系糊料が用いられてきたが
フィルム形成性、フィルム強度の点で満足の行くもので
はなかった。Starch-based sizing agents have conventionally been used as sizing agents for fibers, but they have not been satisfactory in terms of film-forming properties and film strength.
本発明者らは上記の欠点を解決するため鋭意研究を行な
った結果、澱粉にわずかな量のポリビニルアルコールポ
リマーをグラフト共重合せしめることによりフィルム形
成性、フィルム強度、フィルムの柔軟性に非常に優れた
澱粉系繊維用糊剤を得ることを見出し本発明を完成する
に至った。The inventors of the present invention have conducted intensive research to solve the above-mentioned drawbacks, and have found that by graft copolymerizing starch with a small amount of polyvinyl alcohol polymer, the film has excellent film forming properties, film strength, and film flexibility. The present inventors have discovered that a sizing agent for starch-based fibers can be obtained, and have completed the present invention.
すなわち、本発明によって得られるグラフト変性澱粉は
強く柔軟なフィルムを形成するので繊維の耐摩耗性が向
上し、毛羽伏せが十分なされ、毛羽の脱落がすく、かつ
糸切れがすくするため織機効率が非常に高くなる。In other words, the graft-modified starch obtained by the present invention forms a strong and flexible film, which improves the abrasion resistance of the fibers, provides sufficient fluffing, facilitates shedding of fluff, and reduces thread breakage, which improves loom efficiency. becomes very expensive.
更に、ＰＶＡのような常温水可溶物は糊液風整が困難で
ある欠点を有する。Furthermore, a material soluble in room temperature water such as PVA has the disadvantage that it is difficult to prepare the size solution.
すなわち常温で水に触れ粒子表面が溶解すると他の粒子
と固着するいわゆる”ままこ を作り均一に分散溶解し
難く強力な攪拌装置、分散剤を使用しても完全に溶解す
るには長時間を要する。In other words, when the surface of a particle dissolves when it comes into contact with water at room temperature, it forms a so-called "mamako" where it sticks to other particles, making it difficult to disperse and dissolve it uniformly. It takes.
それに対して澱粉は常温水に不溶で加熱糊化性であり、
常温水にまず均一に分散し、懸濁液を作り、しかるのち
撹拌しながら加熱すれば直ちに糊化溶解し均一な糊液が
得られ又、懸濁液をジェットクツカー、ボテーターなど
連続的に送乳すれば急速糊液調製が可能である。On the other hand, starch is insoluble in water at room temperature and gelatinizes when heated.
First, it is uniformly dispersed in water at room temperature to make a suspension, and then heated while stirring to immediately gelatinize and dissolve to obtain a uniform paste. If the baby is fed, it is possible to quickly prepare the glue solution.
本発明者らは上述のような難点を確決すべく種種の研究
を重ねた結果、澱粉にＰＶＡをグラフト共重合させたグ
ラフト変性澱粉を用いることにより澱粉の持つ経済性お
よび使用上の使いやすさ、ＰＶＡの持つ性能上の利点を
かねそなえた繊維用糊剤を見い出し本発明を完成するに
至った。The present inventors have repeatedly conducted various studies to resolve the above-mentioned difficulties, and have found that by using graft-modified starch, which is obtained by graft-copolymerizing starch with PVA, the economic efficiency and ease of use of starch can be improved. The inventors discovered a fiber sizing agent that has the performance advantages of PVA and completed the present invention.
また本発明のグラフト変性澱粉は糊液の調製が従来の繊
維糊剤用澱粉類と同様非常に容易である。Furthermore, the graft-modified starch of the present invention is very easy to prepare as a sizing solution, similar to conventional starches for textile sizing agents.

ことにより得られたグラフト率０．１〜１５チの澱粉−
ポリビニルアルコールグラフト共重合体粒子を用いるこ
とにより冷水時において水不溶性でかつ水に分散が良く
懸濁液を加熱することにより天然澱粉、酸化澱粉などと
同様ままこを作らず容易に糊液が調製できる。Starch with a graft ratio of 0.1 to 15 cm obtained by graft modification and saponification while leaving starch particles.
By using polyvinyl alcohol graft copolymer particles, it is water-insoluble in cold water and has good dispersion in water. By heating the suspension, a paste solution can be easily prepared without forming lumps like natural starch, oxidized starch, etc. can.
グラフト率がこれ以上高いグラフト変性澱粉やグラフト
変性あるいはケン化時に溶解（水又はアルコールにて溶
解）されたグラフト変性澱粉は常温水に溶けるためＰＶ
Ａと同様糊液の調製が困難となる。Graft-modified starch with a higher graft ratio or graft-modified starch dissolved during graft modification or saponification (dissolved in water or alcohol) is soluble in water at room temperature, so PV
Similar to A, it is difficult to prepare the paste.
すなわち冷水時に膨潤を起したり、ままこを作ったりす
るので澱粉のみを繊維用糊剤として使用している工場に
対しては新たな設備が必要となる。In other words, it swells and forms lumps when exposed to cold water, so new equipment is required for factories that use only starch as a sizing agent for fibers.
本発明のグラフト変性澱粉を用いた場合、澱腕ＰＶＡ併
用の時のように別々の糊液を調製したのち混合する必要
もない。When the graft-modified starch of the present invention is used, there is no need to prepare and then mix separate size solutions, unlike when PVA and starch are used together.
澱粉に対するグラフト共重合は酢酸ビニルを澱粉に従来
から知られている各種グラフト方法を用いて澱粉粒子を
崩壊させないで粒子を残したまま行う。Graft copolymerization of starch is carried out using various known methods of grafting vinyl acetate onto starch, leaving the starch particles intact without disintegrating them.

グラフト変性澱粉を製造する場合、元の天然澱粉粒子を
保持したまま水媒中でアルカリを触媒としてケン化を行
うことが経済上および製造上好ましい。When producing graft-modified starch that has heat-gelatinized room-temperature water-insoluble particles similar to natural starch, it is economical and production-friendly to perform saponification in an aqueous medium using an alkali as a catalyst while retaining the original natural starch particles. It is preferable.
