Embodiment 1

[0056] 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 M-layer structure is a single-component or two-component structure; the composite method is hot rolling, or ultrasonic, or Spunlace, or acupuncture and other composite processes.

Embodiment 2

[0058] 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 M-layer structure is a single-component or two-component structure; the composite method is hot rolling, or ultrasonic, or Spunlace, or acupuncture and other composite processes.

Embodiment 3

[0060] 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 M-layer structure is a single-component or two-component structure; the composite method is hot rolling, or ultrasonic, or Spunlace, or acupuncture and other composite processes.

Abstract

The invention relates to an SMS composite packaging material with multi-components and a production method thereof. The material includes two layers of spun-bonded fiber MINERVA and an interlayer which is a layer of melt-blown fiber. The MINERVA layers are bonded with a melt-blown layer through heat boning, acupuncture, spun-lace or ultrasonic; the MINERVA layers comprise two-component fiber and the melt-blown layer comprises one-component fiber. The production method includes the following processes: the fiber ejected by a spun-bonded machinery forms a web; when a web curtain moves to a melt-blown machinery, the melt-blown machinery ejects filaments to the moved web curtain; the web curtain continues to move to the spun-bonded machinery and the filaments are spread on the web curtain by the spun-bonded machinery ejects; at last, the process of strengthening the fiber and the web is carried out to obtain the martial in the invention. The invention not only can be widely used in the packaging material, but also can be used in the aspects of composition, surface-covering, a series of medical composite cloth and electrical wipes. Besides, the invention has the advantages of low melting point, fast sealing, high intensity and uneasy material spilling as well as favorable permeability and low cost.

Description

technical field [0001] The patent of the present invention relates to a packaging material, especially a SMS multi-component composite packaging material and its multi-component spinning method and SMS composite method. Background technique [0002] At present, packaging materials have disadvantages such as poor air permeability, slow sealing, and easy leakage. For example, single-component SMS packaging materials can only be packaged by sewing, which has disadvantages such as low packaging efficiency, high cost, and easy material leakage at the seam; using S or SS packaging materials, the permeable pore size is too large, and material leakage is easy. Single-component fibers have some irreparable shortcomings, and each component fiber has its own advantages and disadvantages; a single spunbonded or melt-blown nonwoven cannot meet the requirements of multiple layers.
