Description
Technical field
The present invention relates to a kind of function synthetic fibre and manufacture method thereof of field of textiles, particularly relate to a kind of polypropylene fiber and manufacture method thereof with hygroscopicity and flexibility.
Background technology
Polypropylene fiber is because low cost of manufacture, have good physical and chemical performance and developed rapidly, but because the hygroscopicity and the flexibility of polypropylene fiber are relatively poor, when making direct contact skin such as underwear, sweat shirt or pressing close to the clothes of skin dress, poor than natural fabric on comfortableness, thereby influenced its application on weaving face fabric.
At present, improve the hygroscopic research of polypropylene fiber and mainly contain following several method:
The one, fiber that hydroscopicity is high and polypropylene fiber carry out blending, pool capital and improve the hygroscopicity of polypropylene fiber, and its shortcoming is to have changed the polypropylene fiber original physical characteristics, has increased product cost simultaneously, has increased difficulty also for dyeing and post processing.
The 2nd, fiber surface is carried out hydrophilic treatment, its shortcoming is a poor durability.
As seen, two kinds of methods fundamentally do not solve polypropylene fiber hygroscopicity problem more than.
The 3rd class methods are, polypropylene fiber is carried out hydrophilic modification, as: molecular structure hydrophilization process, with the monomer-grafted copolymerization method of hydrophiling, fibre structure micropore method etc.The shortcoming of these methods is complex process, the technical difficulty height, and changed the physicochemical characteristics of polypropylene fiber to a certain extent, reduced intensity, dyefastness, feel (influencing or reduced the flexibility of fiber) of fiber etc. potentially, so do not reach the practicability standard as yet.
In sum, the method for fundamentally improving polypropylene fiber hygroscopicity, flexibility at present is ripe not enough, also has certain gap apart from industrial applications, popularization.
Summary of the invention
The present invention intends fundamentally improving the hygroscopicity and the flexibility of polypropylene fiber, and a kind of moisture absorbent soft polypropylene fibre and manufacture method thereof are provided.
Technical scheme of the present invention is to realize like this.
A kind of moisture absorbent soft polypropylene fibre, this fiber is made of montmorillonite or talcum powder functional agglomerate and fibre resin section, and montmorillonite or the weight percent content of talcum powder functional agglomerate in this fiber are 20～30%.
Described montmorillonite or talcum powder functional agglomerate comprise following component, all are weight percentage:
Montmorillonite or talcum powder powder: 10～40%;
Coupling agent: 5～10%;
Dispersant: 10～20%;
Vector resin: 30～75%.
The particle diameter of described montmorillonite or talcum powder powder body material requires to reach submicron order, and maximum particle diameter is no more than 2 microns;
Described coupling agent is any in silane, aluminic acid ester, titanate esters, the aluminium titanium composite coupler;
Described dispersant is any among PE macromolecule wax, PP molecular wax, the EVA;
Described vector resin is the PP resin.
The manufacture method of this moisture absorbent soft polypropylene fibre comprises the following steps:
(1) preparation montmorillonite or talcum powder functional agglomerate: montmorillonite or talcum powder powder body material are dried, and bake out temperature is 110～120 ℃, and drying time is 8～12 hours, and the content that makes moisture in montmorillonite or the talcum powder powder body material is at 40～50PPm; Add coupling agent, vector resin, dispersant in montmorillonite after oven dry or the talcum powder powder according to the above ratio, stir,, make montmorillonite or talcum powder functional agglomerate after twin-screw melt extrudes, cooling, pelletizing.
(2) spinning: above-mentioned montmorillonite or talcum powder functional agglomerate are carried out drying, make its moisture less than 30PPm, add fibre-grade PP resin slicer then, pass through metering device, control montmorillonite or the content of talcum powder functional agglomerate in fiber are 20～30%, by the melt extruded spinning, make moisture absorbent soft polypropylene fibre at last.
Montmorillonite (montmorillonite) has another name called montmorillonite, is the silicate clay ore deposit of a kind of layer structure, flaky crystal.The montmorillonite particle is tiny, and about 0.2～1 micron, the colloid dispersing characteristic is arranged, have very strong adsorption capacity and ion-exchange capacity, also have colloidality, plasticity and the cohesive force of height simultaneously, water imbibition is very strong.Thereby in field extensive uses such as medicine, feed, food, chemical industry, plastics, weaving, cosmetics, environmental protection.Aspect medical, the adsorbable kill bacteria of strong adsorptivity of montmorillonite, still a kind of good smelting tinea medicine.The precedent of making inorganic fabric softener is arranged aspect weaving.Aspect cosmetic applications, have decontamination, detoxifcation, antipruritic, effect such as improve looks, preserve moisture.The present invention wants to utilize these good characteristics of montmorillonite to improve the hygroscopicity and the flexibility of polypropylene fiber.
Talcum powder equally also has very strong adsorptivity, can play the effect that increases fiber softening too.
Principle of the present invention is: utilize coupling agent that montmorillonite or talcum powder powder body material surface are handled, the chemical group that contains close inorganic group and close organic group two class different in kinds because of the coupling agent molecule structure simultaneously, its two classes group is respectively by chemical reaction or physics chemical action, one end combines with powder body material surface, the other end and macromolecule resin tangle or reaction, make powder body material can stablize, combine securely, be beneficial to the carrying out of spinning process with macromolecule resin.Utilize the effect of dispersant simultaneously, make the powder body material particle that is in coalescent state be easy to be dispersed into single particle and also can rely on the even action of coupling agent stably to be distributed in the vector resin.
Usefulness of the present invention is: 1. under the prerequisite of the physicochemical characteristics that does not change polypropylene fiber, fundamentally improved the hygroscopicity and the flexibility of polypropylene fiber effectively, and do not damaged other good characteristics of polypropylene fiber; 2. improved the comfortableness that wears next to the skin of polypropylene fiber lining, utilized montmorillonite or talcous good medicinal properties simultaneously, human body has been produced protection, health-care effect; 3. technical maturity, low cost of manufacture is suitable for industrial applications, popularization.
