Embodiment 1

[0036] (1) 75-80% (percentage by weight) of low-melting polypropylene as the main raw material, 18-23% (percentage by weight) of low-melting ethylene polymer and 2% (percentage by weight) of fatty amides are mixed together, and Add a small amount of color masterbatch.

[0037] (2) According to the spunbond production process, the prepared raw materials are made after feeding 1, melting 2, filtering 3, metering 4, spinning 5, drawing and cooling 6, web forming 7, hot rolling 8, and winding 9.

Embodiment 2

[0039] (1) Mix the low-melt-point polypropylene with a melt index of 36g / 10min and the low-melt-point ethylene copolymer with a melt index of 18g / 10min according to the weight percentage ratio of 4:1, and then add 2% (weight percentage) of fat The color masterbatch of amide compound and 0.2% (percentage by weight) is allocated;

[0040] (2) According to the spunbond production process, the prepared raw materials are made after feeding 1, melting 2, filtering 3, metering 4, spinning 5, drawing and cooling 6, web forming 7, hot rolling 8, and winding 9.

Abstract

The invention relates to a production formula and a production process of non-woven fabrics for medical healthcare. The production process comprises that the steps as follows: low-melting polypropylene materials and other auxiliary materials are mixed and stirred by a three-component automatic measurement mixed feeding system through vacuum feeding to form mixed materials; the mixed materials are extruded and melted by a screw extruder to form a hot-melt body; the hot-melt body is filtered, measured and distributed to a spinning box body for spinning; spun yarn is cooled by side cold wind to obtain primary long yarn; a drafting device carries out air drafting to the primary long yarn; the yarn is paved on a mesh machine to form fiber mesh by a yarn placing device; hot rolling is carried out on the fiber mesh through a hot rolling machine to obtain non-woven materials, and at last the non-woven materials form coiling materials through a coiling machine. The invention has high strength of spunbond non-woven fabrics and has elasticity and plasticity of textiles.

Description

Technical field: [0001] The invention relates to a production formula and production process of medical nonwoven fabric. Background technique: [0002] The spunbond production technology first started in the 1970s, while our country started relatively late in the 1990s. It is a young and promising new technology. It is in line with the long-term development goals of non-woven fabrics in my country and has good development prospects. It is known as the "sunrise industry" in the 21st century. Due to the product's good performance in tensile deformation, breaking strength and elongation, it determines that the application field is very Wide range, mainly in medical protection, clothing, home decoration, industrial fabrics, construction and civil engineering, agriculture and other fields. However, with the progress of the times, humanization of products has become the general trend of the development of the non-woven fabric industry. On the basis of ensuring the original strong ...
