Description
Technical field
The invention belongs to technical field of composite materials, and in particular to a kind of PP composite material and its hydrophilic soft preparing
Application in tough non-woven fabrics.
Background technique
Polypropylene has become one of the leading products of China's high molecular material.2016, domestic polypropylene production capacity was
20,000,000 tons are broken through, yield is up to 1768.8 ten thousand tons.It is polyacrylic to be mainly used for production woven product, film article, injection molding system
Product, textile fabrics etc. are widely used in the fields such as automobile, electronics and household electrical appliances, building pipe, packaging, fiber.Wherein, polypropylene
Fiber material is broadly divided into polypropylene non-woven fabric (also known as nonwoven by its purposes mainly for the production of polypropylene fiber, polypropylene fiber
Cloth), BCF carpet silk, cigarette polypropylene tow etc., it is non-woven fabrics that wherein output is maximum, accounts for 70% of product population or more.
2016, the yield of domestic non-woven fabrics was at 3,000,000 tons or so.The production technology of non-woven fabrics is at present with melt-blown process and spunbond process
For mainstream.In fact, domestic ultra-large type polypropylene non-woven fabric manufacturing enterprise has been completed the compound of melt-blown and spunbond process, with life
It produces based on multi-layer nonwoven fabrics.Non-woven fabrics is widely applied in industries such as building, medical treatment, environmental protection, clothes, automobile, aerospaces, mainly
Using concentrating on high-tech effusion and field of novel.Wherein, application of the polypropylene non-woven fabric in the fields such as medical treatment and beauty
Higher rate of rise is presented.In recent years, with the continuous development of social and economic level, movement of population aggravation, all kinds of infectiousness
Disease repeatedly forms public health event, and medical protection rank, which rises, causes Needs of public health surge, and non-woven fabrics industry is more
It is secondary to have welcome good opportunity to develop.In addition, the demand of traumatism treatment and rehabilitation to dressing swashs with the progress of medical technology
Increase.In addition, putting into disappearing for facial mask beauty every year with the improvement of living standards, people pay high attention to personal beauty
The growth of double figures or more is presented in Fei Jun.In these application fields, polypropylene non-woven fabric shows excellent service performance, and
It is low in cost.
Currently, be applied to the polypropylene non-woven fabric of medical dressing and beauty mask substrate, be mostly by hydrophilic modifying or
The super-fine fiber material of composite spinning technology preparation.Its hydrophilic modifying technique includes corona treatment, hot graft N-vinyl-
2-Pyrrolidone (NVP), ultraviolet irradiation grafted methacrylic acid, interior addition durable hydrophilic auxiliary agent, PVA is modified, chitosan is hydrophilic
Modification, fibroin albumen modification etc., improve the hydrophily of polypropylene non-woven fabric to a certain extent, improve polypropylene non-woven
Comfort and laminating degree when cloth and human skin contact, some products also attached the appearance to healing potion or Cosmetic Ingredient
The amount of receiving.
But, polypropylene non-woven fabric is in the application process of medical dressing and beauty mask substrate, it has been found that even if through
Cross the modified superfine polypropylene non-woven fabrics of hydrophilic modifying or composite spinning, however it remains hydrophily is strong, hydrophily is unstable,
The defects of skin attachement is bad.It is opposite that its main problem is that used hydrophilic treatment process does not assign polypropylene non-woven fabric
Lasting hydrophily, such as addition small molecule hydrophilic agent are inherently bad with non-polar polypropylene fibre compatibility and are easy to move
Out；Plasma or laser treatment are the surface group for being modified polypropylene fibre, and modified effect and unstable；PET and PP
Inherently there is compatibility in blend spinning, and the hydrophily of PET is also not highly desirable.Therefore, if it is desirable to obtain parent
Aqueous stabilization and the polypropylene non-woven fabric for meeting sufferer or beauty demand need to select and polypropylene compatible are good, it is more preferable to have
Hydrophilicity and the high molecular material with good spinnability, are aided with necessary spin finish aid, are total to polypropylene base
The hydrophilic polypropylene dedicated composite material of flexible non-woven fabrics is made in mixed modification, and then cooperates suitable spinning technique acquired
The excellent hydrophilic flexible non-woven fabrics of energy.
