Problems solved by technology

[0003] The width of the existing nonwovens is mostly 1600mm, 2400mm, 3200mm. In the production process of nonwovens, since the length of the spinning assembly corresponds to the width of 1600mm, 2400mm, 3200mm of the nonwovens, the production capacity needs to be increased The width of the spinneret makes it more difficult to cool the spinning, which will cause problems in the production process
Under the influence of stress release of metal materials, uneven deformation at high temperature, and accurate calculation of melt flow channels, stronger control capabilities are required, which brings great difficulty to increase the width and production capacity of existing nonwoven fabrics. , the production cost is very high

Embodiment 1

[0037] Embodiment one: if figure 1 as shown,

[0038] The spinning device for the production of non-woven fabrics is located above the spinning device, used to receive the delivered melt and evenly divide the melt into several streams, including several arranged spinning dies 1 , along the cutting line of the conveyor belt running direction of the swing wire forming device, the number of distributed spinning dies 1 is set equally, and the spinning dies 1 are arranged obliquely with the conveyor belt running direction of the swing wire forming device.

[0039] figure 1 The figure shows five spinning dies 1 arranged in a row, the number of spinning dies 1 can be increased horizontally or vertically according to actual requirements, and the number of spinning dies 1 is only used to better explain this embodiment, five A spinning die head 1 and the conveyor belt running direction of the pendulum web forming device are arranged obliquely, which improves the transverse strength of...

Embodiment 2

[0065] Embodiment two: if Figure 10 As shown, the difference from Embodiment 1 is that the arrangement positions of the spinning dies 1 are different, and the tail ends of the first, second, third, and fourth spinning dies 1 are located on the conveyor belt of the spinning web forming device. On the oblique line set in the running direction, the head ends of the second, third, fourth and fifth spinning dies 1 are located on the oblique line set incline with the running direction of the conveyor belt of the spinning web forming device. The tail end of the first spinning die head 1 and the head end of the third spinning die head 1, the tail end of the third spinning die head 1 and the head end of the fifth spinning die head 1 are on the conveyor belt of the spinning web forming device The cutting line in the running direction is docked so that the number of spinning dies 1 on this cutting line remains the same as other positions. Such as Figure 11 As shown, when carrying out...

Embodiment 3

[0066] Embodiment three: as Figure 12 As shown, the difference from Embodiment 1 is that the arrangement positions of the spinning dies 1 are different, the first and the fourth spinning dies 1 are vertically arranged with the conveyor belt running direction of the pendulum forming device, the second and the third The spinning die 1 and the conveyer belt running direction of the pendulum forming device are arranged obliquely, and an angle combination method is adopted, and the spinning dies 1 are arranged in parallel or at an angle. Wherein the tail end of the second spinning die head 1 and the first end of the third spinning die head 1 are docked on the cutting line of the conveyor belt running direction of the pendulum web forming device, so that the number of spinning die heads 1 on the cutting line remains constant. Same as other locations. Such as Figure 13 As shown, when carrying out transverse and longitudinal stretching, the number of spinning dies 1 is increased a...

Abstract

The invention discloses a spinning device for non-woven fabric production and PP spun-bonded non-woven fabric, PET spun-bonded non-woven fabric and PE spun-bonded non-woven fabric produced by the spinning device. The spinning device comprises a plurality of spinning die heads, the number of the distributed spinning die heads on a cutting line in the running direction of a conveying belt of a yarn swinging and net forming device is equal, and the spinning die heads are inclined and / or vertical to the running direction of the conveying belt of the yarn swinging and net forming device. According to the PP spun-bonded non-woven fabric, transverse fiber distribution is additionally arranged, and MD strength / CD strength is smaller than 1.5. According to the PET spun-bonded non-woven fabric, transverse fiber distribution is additionally arranged, and MD strength / CD strength is smaller than 1.8. According to the PE spun-bonded non-woven fabric, transverse fiber distribution is additionally arranged, and MD strength / CD strength is smaller than 1.8. The product performance is improved, the comprehensive yield is increased, the production speed is increased, the requirement for the control capability is greatly reduced, the production difficulty is greatly reduced, and expansion is facilitated.

Description

technical field [0001] The invention relates to a spinning device for nonwoven fabric production, and also relates to a PP spunbonded nonwoven fabric, a PET spunbonded nonwoven fabric, and a PE spunbonded nonwoven fabric. Background technique [0002] Nonwovens are fabrics formed without spinning and weaving. They are just oriented or random arrangements of short textile fibers or filaments to form a web structure, which is then reinforced by mechanical, thermal bonding or chemical methods. It directly uses polymer chips, short fibers or filaments to form a new type of fiber product with soft, breathable and planar structure through various web forming methods and consolidation technologies. Nonwovens have broken through the traditional textile principles, and have the characteristics of short process flow, fast production speed, high output, low cost, wide application, and multiple sources of raw materials. [0003] The width of the existing nonwovens is mostly 1600mm, 240...
