Description
Technical field
The invention belongs to field of textiles, and in particular to a kind of preparation method of non-woven fabrics.
Background technology
Non-woven fabrics is also known as nonwoven fabric, is a kind of non-woven cloth, it is directly will using high polymer slice, staple fiber or long filament
Then fiber passes through spun lacing by air-flow or machinery networking, needle thorn or hot rolling are reinforced, finally by final finishing formation without volume
The cloth knitted.New type of fibrous product with a soft, breathable and planar structure, advantage are not generate Soft flocks, tough, durable,
As soft as silk and reinforcing material one kind, and the feeling of also cotton, because with cloth appearance and certain performances due tos claim it
For cloth.It not instead of by one one yarns interwoven, woollen yarn knitting together, fiber is directly passed through to the method for physics and is bonded
Together, so, when taking the viscous title in clothes, it finds that, be the end of a thread that can not taken out one by one.
Non-woven cloth breaches traditional weaving principle, and it is short with technological process, throughput rate is fast, yield is high, cost
Low, the features such as purposes is wide, raw material sources are more.Since bonded fabric product is light, environmentally friendly, recyclable, it is widely used in agriculture
With film, shoemaking, process hides, mattress, child-mother-covering, decoration, chemical industry, printing, automobile, building materials, the industries such as furniture.Non-woven fabrics is more at present
Using polypropylene（Pp materials）Pellet is raw material, batches continuous one-step through high-temperature fusion, spinneret, paving guiding principle, hot pressing and produces.
Although achieving good effect, wear-resisting property is poor, antibiotic property is insufficient, and needs non-woven fabrics to have height in some fields
Wear-resisting, high anti-microbial property, non-woven fabrics in the prior art cannot be satisfied the requirement, therefore, produce a kind of wear-resisting, antibacterial nothing
Woven fabric has become the task of top priority.

Addition extra weight makes to be fully immersed in synthetic perspiration, and then beaker is placed in 35 DEG C of insulating boxs and stands 12h, takes out nothing
Woven fabric, which is washed with distilled water, dries, and is tested as 1 sweat proof.And so on test sample bacteriostasis rate, test strain be it is golden yellow
Color staphylococcus, test result are shown in Table 1.
Table 1：
| Test event | Embodiment 1 | Embodiment 2 | Embodiment 3 | Comparative example |
| Air permeability | 21 | 18 | 21 | 15~17 |
| Rupture strength（Mpa/min） | 3.11 | 2.88 | 2.83 | 2.1~2.31 |
| Sterilizing rate（Staphylococcus aureus ATCC6538）, % | 96.3 | 97.3 | 96.6 | 73.4~78.2 |
In summary, non-woven fabrics good anti-bacterial effect of the invention, wearability is high, complies fully with use demand, is worth of widely use.
