Abstract
The invention relates to a production process of a low-twist stranded wire with a special structure, and belongs to the technical field of spinning. According to the production process of the low-twist plied yarn with the special structure, two short fiber yarns forming the plied yarn are subjected to high-pressure airflow vertical to the yarn direction in the unwinding process, the positions of the two short fiber yarns are frequently exchanged under the action of the airflow to form weak twist without fixed twisting direction, meanwhile, outer layer fibers of the two single yarns are blown away to form longer hairiness, the hairiness is entangled with each other to form tight combination, and finally the low-twist plied yarn without fixed twisting direction is obtained. The method has the advantages of convenient operation, short period and low cost, not only keeps the soft comfort degree of the single yarn, but also increases the advantages of high strength, good wear resistance and the like of the plied yarn, can effectively overcome the defects of low strength, easy yarn breakage and the like in the weaving process of the yarn, ensures that the finished fabric has softer and smoother hand feeling, and can improve the added value of the fabric.
Description
Technical Field
The invention relates to a production process of a low-twist stranded wire with a special structure, and belongs to the technical field of spinning.
Background
The single yarn is made by spinning short fiber, arranging the short fiber along axial direction and twisting. Low strength and poor wear resistance. When the fabric is woven, the yarn is easy to break, and the production rate is low. And the fabric is easily torn. Certain functional finishing can not be carried out during the post-finishing processing to increase the added value of the fabric.
The plied yarn is a yarn formed by twisting two or more single yarns. The strength and the wear resistance of the yarn are better than those of single yarn. Typically for medium thickness strong fabrics. Because the two single yarns are twisted, the plied yarns are hard and solid, and the hand feeling of the woven fabric is slightly hard. In the process of twisting single yarn into folded yarn, the process of doubling and double twisting is needed, and the processing flow is too long.
Disclosure of Invention
The invention aims to provide a production process of low-twist stranded yarns with special structures, which is convenient to operate, short in period and low in cost, not only keeps the soft comfort degree of single yarns, but also increases the advantages of high strength, good wear resistance and the like of the stranded yarns, the defects of low strength, easiness in yarn breakage and the like can be effectively overcome in the weaving process of the yarns, the finished fabrics are softer and smoother in hand feeling, and the additional value of the fabrics can be improved.
According to the production process of the low-twist plied yarn with the special structure, two short fiber yarns forming the plied yarn are subjected to high-pressure airflow vertical to the yarn direction in the unwinding process, the positions of the two short fiber yarns are frequently exchanged under the action of the airflow to form weak twist without fixed twisting direction, meanwhile, outer layer fibers of the two single yarns are blown away to form longer hairiness, the hairiness is entangled with each other to form tight combination, and finally the low-twist plied yarn without fixed twisting direction is obtained.
The two spun yarns A and the two spun yarns B are unwound simultaneously and combined into a double yarn C, the double yarn C quickly passes through a vertical high-pressure nozzle to generate a folded yarn D, and the folded yarn D generates a cone yarn E through a winding device.
The yarn A and the yarn B are original yarns or colored yarns of ring spinning or compact spinning, and the yarn A and the yarn B are yarns with the same yarn count and color or yarns with different yarn counts and colors.
The high-pressure nozzle air flow blows in perpendicular to the yarn direction and blows out along the yarn radial direction, and the air pressure is preferably 0.5-1MPa.
Preferably, the speed of the twin yarn C through the vertical high-pressure nozzle is in the range of 500 to 1000m/min.
Two single yarn hairiness in the folded yarn D are mutually entangled and combined, the average twist is 1-5 twists/inch, and the fixed twist direction is not available.
The density of the cone yarn E is 0.33-0.5g/cm 3 The cone yarn E is normally used subsequently or used after the cone yarn dyeing process.
Compared with the prior art, the invention has the following beneficial effects:
(1) The low-twist plied yarn produced by the invention not only keeps the soft comfort degree of single yarn, but also increases the advantages of high strength, good wear resistance and the like of plied yarn, the defects of low strength, easy yarn breakage and the like can be effectively overcome in the weaving process of the yarn, the finished fabric is softer and smoother in hand feeling, and the added value of the fabric can be improved;
(2) The production process flow is short, the doubling and double-twisting processes are combined into a whole, the speed of the equipment is about 20 times that of the existing double-twisting machine, the production efficiency can be improved, and the production cost can be reduced;
(3) The average twist of the yarn obtained by the invention is 1-5 twists/inch, the twist direction is not fixed, and when two yarns with different colors or different raw materials are used for plying, the produced fabric has a unique leisure style.
