Bubble type flexible non-woven cloth and manufacturing method thereof

Abstract

The invention discloses a piece of bubble type flexible non-woven cloth and a manufacturing method of the bubble type flexible non-woven cloth. Raw materials, namely, polylactic acid high polymers, are solidified into the cloth through melt spinning net laying and twice hot rolling. Annular nips are formed through the first time of hot rolling, point nips are formed through the second time of hot rolling, and finally the bubble type non-woven cloth is formed. Due to the fact that the nip area is small and the three-dimensional structure is obvious, the non-woven cloth is excellent in flexibility, small in contact area when making contact with the skin, fresh and cool, can not be attached to the human body, enables a user to feel nice and cool, and can be widely applied to disposal medical treatment and public health products such as sanitary towels, paper diapers, adult incontinence trousers, surgical gowns and operation cushions through combination with the advantages of polylactic acid fibers. Meanwhile, the polylactic acid raw materials have the advantages that the polylactic acid raw materials can be completely and naturally circulated and can be decomposed in a biological mode, energy consumption is lowered, and the environment protection role is played.

Description

technical field [0001] A bubble-type soft non-woven fabric, especially a non-woven fabric that is spun into a net by polylactic acid and undergoes a double-hot rolling consolidation process. Background technique [0002] From 2008 to 2009, the world experienced a global economic recession, and the non-woven fabric industry was also greatly affected. Especially in Western countries such as Europe and the United States, the growth of non-woven fabrics also slowed down or stagnated accordingly. The economy began to recover in 2010, and the development of nonwovens returned to a rapid growth momentum. According to the survey of relevant international agencies, the global demand for nonwovens will grow at an annual rate of 6.9% in the years before 2015. In particular, the growth rate of low-gram weight products is faster, with an annual growth rate of 7.2%, which can be seen from the great development of technologically advanced low-gram heavy-weight spinning and melting nonwove...

Problems solved by technology

[0003] With the development, people's requirements for non-woven fabrics are getting higher and higher, and many requirements have been put forward for the production of non-woven fabrics. Comfort is undoubtedly the most important requirement for non-woven fabrics that are in contact with the skin. The soft finishing of cloth mainly adopts the modification of raw materials, but the cost is very high, which has an impact on the environment and skin safety, which limits the development of this method. There are also non-woven fibers spun finely to achieve the purpose of softness, but the effect of softness is very limited. Yes, and the equipment requirements are high, and the output is also very low
