た保全性を与える糸の製造に関する。Description: FIELD OF THE INVENTION The present invention relates to yarns used in the paper industry to make absorbent fabrics or felts for machinery. More particularly, the present invention relates to the production of yarns in which the fibrous structure is completely impregnated and coated with an agent such as a thermoplastic polymer, thereby providing an integrated integrity to the final structure.

保全性の糸がしばしばその結果物である。PRIOR ART AND PROBLEMS In the methods commonly used for coating yarns, it has been found that it is difficult for the coating or encapsulant to penetrate the core of the yarn structure due to the density of the individual yarns. As a result, the impregnation is often incomplete and some air remains trapped in the area between these individual fibers. Suboptimal strength and integrity yarns are often the result.

繊維の移動方向に次第に狭くなり、または先細になる。SUMMARY OF THE INVENTION It is an object of the present invention to provide a yarn in which the fibers are completely encapsulated and embedded in a desired coating and a means for producing such a yarn. This has been achieved by producing a card roving comprising two types of staple fibers having different melting temperatures, as in the case of nylon and polyester, for example. The card roving is then twisted to the desired tightness, expressed in twists per inch, and then passed through an orifice of a heating die. The hole in the die tapers or tapers in the direction of movement of the fiber being passed.

テーパーは溶融流体を圧縮し存在する気泡を押し出す。The temperature of the die needs to be controlled so that only fibers having a low melting temperature become flowable and flow completely around fibers having a high melting temperature. At the same time, the temperature must be lower than the temperature that damages the coated and encapsulated fibers. The untwisted fiber strands are unaffected by heat and fiber to the same degree of tightness. In addition, the taper of the die compresses the molten fluid and pushes out any bubbles that are present.

い撚糸ステープル繊維の構造を有している。As the structure exits the die, the molten fluid solidifies as it is cooled by ambient air. The resulting yarn has the structure of a twisted staple fiber which is completely bound by the thermoplastic and which is free of trapped air bubbles.

ことが重要であり、それ故本発明の方法は特別の性質を
有する糸を製造するように統計し得る。Blends were tested where the low melting temperature fibers accounted for 25% to 75% by weight of the combination. In fact, the choice of the ratio of low-melting fiber to high-melting fiber is governed by the required fiber encapsulation. It is important to note that in general, the higher the percentage of low melt fiber, the more stiff the resulting yarn will be, so the method of the present invention can be statistically produced to produce yarns with particular properties. .
これらの糸は利点は強度、一様な構造保全性、及び熱
可塑性被覆物中の繊維の完全は封入である。The advantages of these yarns are strength, uniform structural integrity, and complete encapsulation of the fibers in the thermoplastic coating.

This retainer supplies the necessary heat to the die 4. The heat from the die 4 melts the cold melt component 2, and the compression resulting from the taper in the die 4 during the passage through the die 4 causes the melted cold melt component 2 to completely surround the fibers of the hot melt component 3. Push it. Air remaining in the voids between the fibers of the high-temperature melting component 3 is extruded by the compression action of the die 4. Strands of yarn 6 made of fibers of the hot melt component 3 coated with the low melt component 2 and fully impregnated emerge from the die 4 on the right side of FIG.
