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 technology
Polypropylene has become one of leading products of China's high polymer 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 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 mainly for the production of polypropylene fiber, and polypropylene fiber is broadly divided into polypropylene non-woven fabric by its purposes and (is also known as nonwoven
Cloth), BCF carpet silks, cigarette polypropylene tow etc., wherein output it is maximum for non-woven fabrics, account for more than the 70% of product population.
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 main flow.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
Produce based on multi-layer nonwoven fabrics.Non-woven fabrics is in industry extensive uses such as building, medical treatment, environmental protection, clothes, automobile, Aero-Space, mainly
Using concentrating on high-tech effusion and field of novel.Wherein, application of the polypropylene non-woven fabric in the field such as medical treatment and beauty
Higher rate of rise is presented.In recent years, continuing to develop with social economy's level, movement of population aggravation, all kinds of infectiousness
Disease repeatedly forms public health event, and medical protection rank, which rises, triggers Needs of public health to increase sharply, and non-woven fabrics industry is more
It is secondary to have welcome good opportunity to develop.In addition, with the progress of medical technology, traumatism treatment and rehabilitation swash to the demand of dressing
Increase.In addition, with the improvement of living standards, people are paid high attention to personal beauty, disappearing for facial mask beauty is put into every year
Growth more than double figures is presented in Fei Jun.In these application fields, polypropylene non-woven fabric shows excellent performance, and
It is with low cost.
At present, applied to medical dressing and the polypropylene non-woven fabric of beauty mask base material, be mostly by hydrophilic modifying or
Super-fine fiber material prepared by composite spinning technology.Its hydrophilic modifying technique include corona treatment, hot graft N-vinyl-
2-Pyrrolidone (NVP), ultraviolet irradiation grafted methacrylic acid, interior addition durable hydrophilic auxiliary agent, PVA are modified, chitosan is hydrophilic
Modified, fibroin albumen modification etc., improves the hydrophily of polypropylene non-woven fabric, improves polypropylene non-woven to a certain extent
Comfort and laminating degree when cloth is with contact human skin, some products also addition of 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 base material, it has been found that even if through
Cross the superfine polypropylene non-woven fabrics that hydrophilic modifying or composite spinning are modified, however it remains hydrophily, strong, hydrophily is not unstable,
The defect such as skin attachement is bad.It is relative that its subject matter is that used hydrophilic treatment process does not assign polypropylene non-woven fabric
Lasting hydrophily, such as addition small molecule hydrophilizing agent be not inherently good and be easy to move with non-polar polypropylene fibre compatibility
Go out；Plasma or laser treatment are the surface group for being modified polypropylene fibre, and modified effect and unstable；PET and PP
Blend spinning, the problem of inherently there is compatibility, and PET hydrophily are nor highly desirable.Therefore, if it is desirable to obtain parent
Aqueous stabilization and meet the polypropylene non-woven fabric of sufferer or beauty demand, it is necessary to select with polypropylene compatible it is good, with more preferable
Hydrophilicity and the high polymer material with good spinnability, are aided with necessary spin finish aid, are total to polypropylene base
Mixed modification, is made the hydrophilic flexible polypropylene dedicated composite of non-woven fabrics, and then coordinate suitable spinning technique acquired
The excellent hydrophilic flexible non-woven fabrics of energy.
The content of the invention
In place of the shortcoming and defect existed for prior art, primary and foremost purpose of the invention is that providing a kind of polypropylene answers
