Problems solved by technology

The patent (CN108866785A) mentions a yarn feeding device for elastic yarn in a flat knitting machine. By adding a buffer arm and a torque generator to the yarn feeding mechanism to control the stability of the tension of the elastic yarn, a large number of refitting and corrections are required for the machine. A large number of yarn guide devices are installed, which increases the possibility of frictional adhesion between the naked ammonia filament and the yarn guide devices

Embodiment 1

[0035] Such as figure 1 , this embodiment provides a yarn feeding device for naked ammonia silk plated flat knitted fabrics, including: a first yarn feeder 1, a second yarn feeder 2, naked ammonia silk 3, ordinary yarn 4, and a roller channel 5 , Yarn guide channel 6, naked ammonia yarn tube 7, yarn guide roller 8, constant tension yarn feeder 9, buffer roller 10, buffer arm 11, flat knitting machine head 12, flat knitting machine;

[0036] There is a yarn guide roller on both sides of the upper part of the first yarn feeder 1, a yarn guide porcelain eye is respectively arranged on both sides of the middle part of the first yarn feeder 1, and the bottom of the first yarn feeder 1 is a yarn feeding hole , the first yarn feeder 1 and the second yarn feeder 2 have the same structure, the first yarn feeder 1 is used to feed ordinary yarn 4, and the second yarn feeder 2 is used to feed naked ammonia silk 3, so The first yarn feeder 1 is set on one side of the second yarn feeder 2...

Embodiment 2

[0049] This embodiment provides a weaving method of naked ammonia silk plated flat knitting fabric, which is to realize constant tension yarn feeding of naked ammonia silk when the machine head is running and knitting, so as to ensure the smoothness of the cloth surface. The methods include:

[0050] Step 1: the naked ammonia yarn 3 enters the constant tension yarn feeder 9 from the naked ammonia yarn drum 7 through the yarn guide roller 8, and after the tension balance is performed by the constant tension yarn feeder 9 (the constant tension yarn feeder itself has a yarn storage function, it starts When a certain balance tension is reached, when the yarn feeder detects that the tension becomes larger, increase the amount of yarn feeding; when it detects that the tension is too small, stop yarn feeding, and continue feeding until the yarn tension reaches the set value), and then pass in The buffer roller 10 and the buffer arm 11 control the margin of the naked ammonia silk thro...

Abstract

The invention discloses a weaving method of a bare spandex yarn plated flat knitted fabric and a yarn feeding device of the bare spandex yarn plated flat knitted fabric, and belongs to the technical field of textile product production. The device comprises a first yarn nozzle, a second yarn nozzle, a bare spandex yarn cylinder, a yarn guide roller, a constant tension yarn feeder, a buffer roller,a buffer arm, a flat knitting machine head and a flat knitting machine; the first yarn nozzle and the second yarn nozzle are arranged on a yarn nozzle rail of the flat knitting machine, the bare spandex yarn cylinder is arranged on a creel above the flat knitting machine head, and the buffer roller and the buffer arm are arranged on one side of the flat knitting machine head; and the constant tension yarn feeder is arranged on the upper side of the buffer roller, and the yarn guide roller is arranged on the side of the constant tension yarn feeder. According to the weaving method of the bare spandex yarn plated flat knitted fabric and the yarn feeding device of the bare spandex yarn plated flat knitted fabric, bare spandex yarn is fed into a yarn nozzle hole in the high position, and simple yarn is fed into a yarn nozzle hole in the low position, so that two yarns form relatively large difference in longitudinal angles of the inlay to ensure that the simple yarn is always exposed on the front side of the fabric in a plating structure, and the spandex yarn is always on the back side of the fabric to avoid the phenomenon of turning over the yarn and exposing the bottom.

Description

technical field [0001] The invention relates to a method for weaving naked ammonia silk plated flat knitted fabrics and a yarn feeding device thereof, belonging to the technical field of textile product production. Background technique [0002] After the traditional clothing is cut with naked spandex yarn, the spandex on the edge of the fabric shrinks with the increase of wearing and washing times, which is easy to form curling and loosening, affecting the appearance and wearing performance of the fabric. The pattern and structure of garments produced by flat knitting machines can be varied, and partial weaving can also be used to reduce the cutting of fabrics during molding. The fully formed knitted sweater also has the advantage of one-piece forming, achieving zero cutting. In the weaving process, elastic yarns are often inserted to increase the elasticity of knitted fabrics. At present, when weaving high-elastic fabrics on fine-needle flat knitting machines, the use of s...
