Description
Technical field
The present invention relates to a kind of preparation method of needle punched non-woven fabrics, belong to nonwoven fabric manufacture field.
Background technology
Needle punched non-woven fabrics is the one of dry method nonwoven fabric, the principle of needle point method nonwovens process utilizes the pricker of triangle section (or other cross sections) seamed edge band barb to carry out bob-weight puncture to fibre web, when barb is through fibre web, fibre web surface and the strong short thrust of local nexine fiber are entered fibre web inside.Due to the rubbing action between fiber, originally fluffy fibre web is compressed.When pricker exits fibre web, the fibre bundle barb thrust and staying in fibre web.Like this, many fibre bundles tangle fibre web, make it can not recover original fluffy state again.Through acupuncture many times, considerable fibre bundle is thrust fibre web, makes fiber in fibre web entangled to each other, thus forms the needle point method nonwoven material with certain brute force and thickness.
The manufacturing process technological process of existing needle punched non-woven fabrics is complicated, and equipment needed thereby is complicated, made needle punched non-woven fabrics brute force, bulkiness, water-permeable and air permeable poor-performing.
Therefore, be necessary to improve the composition of raw materials of existing needle punched non-woven fabrics and technique manufacturing process, manufacturing process technological process is shortened, and equipment is simple, brute force, bulkiness, the water-permeable and air permeable better performances of obtained needle punched non-woven fabrics.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the invention provides the preparation method of needle punched non-woven fabrics, can improve original technical recipe and preparation method, technological process is shortened, device structure is simple, product has the features such as grammes per square metre is even, fracture strength is high, tearing strength is large, Heat stability is good, also has good bulkiness, water-permeable and air permeable simultaneously.
