Problems solved by technology

The usual non-woven fabric production line requires that the fiber length not exceed 65mm. Using long fibers as raw materials has a series of special requirements for the non-woven fabric production line. It is considered uneconomical to allocate a special production line to meet these requirements. Therefore, use It is difficult to make puncture-resistant nonwoven fabrics with longer fibers in industrial production. In addition, although fluffy materials are conducive to the improvement of puncture-resistant performance, they lead to bloated products and inconvenience to users.

Embodiment 1

[0014] Embodiment 1: Carry out high-performance fiber nonwoven single-layer composite treatment with the method of the present invention, and the overall density during composite is no more than 600g / m 2 : The high-performance fiber non-woven fabric rolls with a width of 1.5m and a length of 100m are sorted and placed on the unwinding frame of the ultrasonic sewing machine. The ultrasonic sewing machine used has 10 generator heads, and the output power of the generator is 600w× 10. The working frequency is 20Khz, and the non-woven fabric passes through the generating head at 5 m / min. Manually adjust the pressure until the junction is clear. Rolled by roll-forming equipment at the import and export ends, the thickness of the nonwoven fabric sewn by the method of the present invention is reduced by 10%-20%, and the anti-stab performance is improved by about 5% after testing.

Embodiment 2

[0015] Embodiment 2: Carry out double-layer composite treatment of high-performance fiber nonwovens with the method of the present invention, and the overall density during composite is no more than 600g / m 2 : Put 2 rolls of high-performance fiber non-woven fabric rolls with a width of 1.8m and a length of 100m, arrange them on the unwinding frame of the ultrasonic sewing machine, and perform double-layer lamination. The ultrasonic sewing machine adopted has 12 generating heads, the output power of the generator is 600w×12, the working frequency is 20Khz, and the nonwoven fabric passes through the generating heads at 3 m / min. Manually adjust the pressure until the junction is clear. At the import and export end of the line, it is rolled by a roll-forming equipment, and the thickness of the non-woven fabric after stitching is reduced by 15%-25%, and the performance of the test is increased by about 5%.

Abstract

The invention relates to a method for using ultra-sonic wave seaming method to improve the anti-piercement property of fiber non-weave cloth, which comprises: arranging the treated fiber non-weave cloth on the unwind support of ultra-sonic wave seaming machine; then at preset speed, feeding it between the seaming machine and the cam roller, to be compressed and form adhesive point when passing the cam roller; hand-operated adjusting the pressure until the adhesive point is clear; at the outlet, using winding machine to coil said cloth. The invention can reduce the thickness of non-weave cloth, to realize higher property and lower weight.

Description

technical field [0001] The invention relates to a treatment method for improving the anti-puncture performance of high-performance fiber non-woven fabrics. In particular, it relates to a processing method for improving the anti-puncture performance of the non-woven fabric by means of ultrasonic seam compounding. Background technique [0002] Due to the excellent puncture resistance of high-performance fiber nonwovens, they are usually used to make soft stab-resistant clothing. A large number of experiments have proved that the bulkiness of nonwovens is directly related to the anti-puncture performance. The anti-puncture function of high-performance fiber nonwovens comes from the fiber resistance of high-strength fibers to punctured objects in the nonwoven structure. Hysteresis. This effect is related to the moderate migration of short segments of individual fibers, so it is necessary for the material to maintain a certain bulk. The qualitative relationship between materia...
