Conventionally, as a processing method of a composite processed yarn of a thermoplastic synthetic fiber multi-filament yarn (hereinafter referred to as a thermoplastic multi-filament yarn) and a recycled fibrous fiber multi-filament yarn (hereinafter referred to as a recycled fiber multi-filament yarn), a thermoplastic multi-filament has been used. Many methods are known, such as ply-twisting process of filament yarn and recycled fiber multi-filament yarn, relaxation heat treatment after ply-twisting process, and simultaneous simultaneous false-twisting process,
The yarns obtained by these conventional techniques have almost no entanglement between the thermoplastic multifilament yarn and the regenerated fiber multifilament yarn between the single filaments, and both yarns are separated from each other to form a group. Therefore, in the fiber knitted products using the yarns obtained by these conventional techniques, the features of the both yarns simply appear, and the texture and the hedonic tone become monotonous, and conversely the fiber mixing property is high. From bad things, mottled,
It has the drawback that streaks and steps are likely to occur. A composite yarn in which a thermoplastic multifilament yarn and a recycled fiber multifilament yarn are combined and subjected to a fluid treatment has also been proposed.This type of composite yarn is (a) an interlaced type yarn mainly composed of interlaced yarns, ) It is roughly classified into a Taslan type in which many loops are generated on the yarn surface, a type with a feeling of volume is not obtained in the type of (a), and a type of (b) has good drapability The reality is that the That is, the characteristics and drapeability of the thermoplastic multifilament yarn and the recycled fiber multifilament yarn may be diminished by loops and entanglement, and the texture and performance of the woven and knitted product become halfway. In many cases, the usage is restricted. Further, in the case of the Taslan type composite yarn of (b), many loops and slacks of thermoplastic multifilaments are generated over the entire yarn, and they are tightly entangled to form a robust form, so that the supple texture It is difficult to obtain a woven or knitted product and the surface of the product has many loops, so when the surfaces of the products come into contact with each other, the loops are caught with each other, causing a so-called fastener phenomenon. It has drawbacks such as being easy to give discomfort to. As a method of improving these, a method has been proposed in which a fluid treatment is performed using a low-strength yarn and a high-strength yarn, the low-strength yarn is cut, and a loop and cut fluff are mixed in the yarn. Also, in the case of the yarn, since the strength of the supplied yarn itself is low, the filament is apt to be cut when traveling in the yarn path before the yarn enters the fluid treatment area, so that the workability is poor and the quality of the obtained yarn is stable. There are inherent problems such as lack of sex.

As described above, the method of the present invention is characterized in that the yarn B, which is supplied to the fluid jet nozzle together with the yarn A and is subjected to the disturbance treatment by the jetting fluid, is moistened. The position to perform is such that while the single filaments forming the yarn B reach the take-up roller after the fluid ejection nozzle,
Although it may be performed at any position as long as it is partially cut, it is specifically between the supply roller and the fluid ejection nozzle illustrated in FIGS. 1 and 2. For other positions,
It can be performed inside the fluid injection nozzle, at the yarn inlet or the yarn outlet. Further, the moistening treatment may be performed by any method as long as the yarn B is wetted with water. For example, it may be applied to both the yarn A and the yarn B, or to either one. For example, even if the yarn A of the thermoplastic multifilament yarn is wet-treated by the moisturizing device provided between the supply roller and the fluid ejection nozzle as shown in the figure, the water attached to the yarn A in the fluid ejection nozzle is treated. A part of the yarn is transferred to the yarn B, and the purpose is sufficiently achieved. What is necessary is that the required yarn B is in a wet state when being disturbed by the jetting fluid.

i) The difference between the wet knot strength AW of the yarn A and the wet knot strength BW of the yarn B must be 1.5 g / d or more.
If the difference in strength is less than 1.5 g / d, the monofilaments of both yarns A and B will be cut to the same extent by the fluid treatment, or both yarns A and B will not be cut easily. , It is very difficult to set the fluid treatment conditions.

iii) It is necessary that the knot strength BD of the yarn B in the standard state is 1.7 g / d or more and the dry-wet knot strength ratio BW / BD is 0.6 or less. Outside these conditions, before fluid treatment. However, problems such as the breakage of the monofilament are likely to occur, and the stability of the morphology is poor because the strength of the fluff itself of the obtained composite yarn is low.

In the method of the present invention, the fluid treatment forms a large number of loops and sags in the multifilament yarn due to the disturbing action of the jet fluid. This can be achieved by using a conventionally known fluid ejection nozzle. In addition to the above-mentioned strength conditions, the degree of formation of loops and slack and the cutting of the filaments of the yarn B by the fluid treatment, the fineness of each yarn, the characteristics such as Young's modulus, the supercharging rate, the jetting fluid pressure, etc. It can be arbitrarily set by selecting various conditions.

As described above, the method of the present invention combines the yarn A of the thermoplastic multifilament yarn with the yarn B of the recycled fiber multifilament yarn which has a relatively high strength in the standard state and causes a predetermined strength decrease due to wetting. In addition, the yarn B is subjected to fluid treatment in a wet state to form a large number of loops and slack, and at the same time, the single filaments of the yarn B are partially cut to form cut fluff. This is a skillful use of the filament's elongation behavior, twisting, etc. due to the strength reduction behavior under wetting and the disturbing action of the jet fluid. Therefore, there is no trouble such as filament breakage in the process before the fluid treatment, processing at high speed is possible, and since the fluid treatment is under moistening, the entanglement effect of both yarns and the loop forming effect are achieved. It can be remarkably improved, and the composite yarn with stable quality can be efficiently manufactured.

Further, the composite yarn obtained by the method of the present invention is a regenerated fiber filament in which a part of the filaments constituting the filament is excellent in moisturizing property and drapability, and the filament is randomly cut, When used as a woven or knitted fabric, not only the texture and appearance of spun yarn, but also an excellent product with a supple touch and a refreshing texture are obtained. On the other hand, since the thermoplastic multifilament forms loops and slacks and is entangled with the regenerated fiber multifilament that has become cut fluff, the original tension, waist and bulkiness are not excessively exhibited, and the regenerated fiber multifilament is not exhibited. It harmonizes with the drape property of the yarn and the touch of spun yarn due to the cut fluff. Furthermore, since there is a difference in dyeability between the thermoplastic multifilament yarn and the regenerated fiber multifilament yarn, a heathered product is obtained, and further, one of them is a loop and the other is a cut fluff. Heather is fine. Since the cut fluff is a non-pilling regenerated fiber filament and the thermoplastic filament forms a loop having a characteristic that pilling is unlikely to occur, the product has extremely excellent anti-pilling property.
