Embodiment 1

[0034] The MINERVA layer is a continuous multi-component spunbond fiber, the fiber is selected from a skin-core structure (see Figure 4), the skin layer is PE, which can be HDPE (high-pressure polyethylene) or LDPE (low-pressure polyethylene), and the core layer is PET. The proportion of PE components is 10%-90%, and the proportion of PET components is 90%-10%. The composite method is ultrasonic composite.

Embodiment 2

[0036] The MINERVA layer is a continuous multi-component spunbond fiber, the fiber is selected from the skin-core structure (see Figure 4), the skin layer is PE, which can be HDPE (high-pressure polyethylene) or LDPE (low-pressure polyethylene), and the core layer is PP. The proportion of PE components is 10%-90%, and the proportion of PP components is 90%-10%. The composite method is ultrasonic composite.

Embodiment 3

[0038] The MINERVA layer is a continuous multi-component spunbond fiber, the fiber is selected from a side-by-side structure (see Figure 5), the first component is PE, which can be HDPE (high-pressure polyethylene) or LDPE (low-pressure polyethylene), the other component for PET. The proportion of PE components is 10%-90%, and the proportion of PET components is 90%-10%. The composite method is ultrasonic composite.

Abstract

The invention relates to a polycomponent spunbonded unwoven rib-added composite material and a preparation method thereof. The material comprises two spunbonded MINERVA layers (1, 3) consisting of PE and PP or PET, and a rib-added middle layer (2) consisting of PE or PET or PP lament fibres, the three layers are adhered together by a reinforcement mode such as hot rolling, supersonic wave, spunlace and needling. The preparation method is as follows: the fibres ejected from a spunbonding machine (4) form a web; when a web curtain reaches an unwinding device (5) which spreads a grid or leno fabric shaped layer on the arrived web curtain; the web curtain continues to move to the spunbonding machine, and threads ejected from the spunbonding machine are spread on the web curtain again; finally, the polycomponent spunbonded unwoven rib-added composite material is obtained through technologies such as fibre web reinforcement, etc. The composite material has the advantages of high strength, high peeling strength and low gram weight. The material can be widely applied to earthwork cloth, agricultural cloth, synthetic leather substrates, construction materials, special military unwoven materials, filtering materials, clothes and packaging materials, etc.

Description

technical field [0001] The invention belongs to the field of composite materials and preparation, in particular to a multi-component spun-bonded non-woven reinforced composite material and a preparation method thereof. Background technique [0002] At present, in the case of high strength requirements in the fields of geotextile materials, agricultural cloth materials, synthetic leather base cloth materials, construction materials, special military non-woven materials, filter materials, clothing materials, packaging materials, etc., the weight will generally be very high. Large, so that its application is greatly restricted, and there is poor air permeability, especially when sealing performance is required, there are disadvantages such as slow sealing and easy opening. Single-component spunbond fabric cannot meet the requirements of high strength, good sealing performance, and high peel strength. Multi-component spunbond non-woven reinforced composite materials not only hav...
