Description
Technical field
The present invention relates to textile process technology field, in particular to one anti-aging modified dacron and its processing method are described
Anti-aging modified dacron color fastness is high, and yarn strength loses small when using outdoors.
Background technique
Has many advantages, such as color fastness height in view of acrylic fabric, strength loss degree is small, therefore acrylic fabric is widely used in
In the preparation of outdoor products.However the generally existing fatal problem of these acrylic products: it is difficult to be located after discarded
Reason, that is to say, that as soon as being embedded in beneath 100 years all imputrescibilities after these acrylic products are rejected, this causes environment
Greatly load and pollute,
Acrylic is compared, another fibre object -- terylene has just well solved the problem of product subsequent processing pollutes, but
It is that current terylene product on the market can not meet the needs of outdoor goods well.Specifically, outdoor goods are due to it
Beautiful and practical consideration generally requires to carry out its fabric dyeing processing, but due to the macromolecular structure of terylene itself
Terylene itself is caused to be easy aging, fission, this is just simultaneously it is meant that common dyeing terylene product and terylene original liquid coloring product
Often color fastness is very poor, and after 78 hours serious colour fading just occurs for conventional terylene product under solar radiation, in day illumination
The strength damage of itself is also very big after penetrating 360 hours, this just dramatically limits dacron product outdoors on articles
Using.
In other words, since this body structure of terylene is easy aging, the colorant molecule on terylene product being colored is easily separated from
Terylene molecule, so that terylene product fades seriously.In addition, after serious aging occurs for terylene, it is loosely organized or disconnected
It splits, so that but also the intensity of terylene product by very big loss, makes the terylene product of current routine for these reasons
It cannot be applied to outdoor products well.
Summary of the invention
The purpose of the present invention is to provide an anti-aging modified dacron and its processing method, the anti-aging modified dacron is anti-

It does not change.
In an embodiment of the present invention, the anti-aging master batch be selected from 18-22% proportion hindered amine light stabilizer with
And the combination of the ultraviolet absorbing agent of 10-12% proportion.
The Masterbatch main function is for painting to terylene, and Masterbatch is by a high proportion of pigment or additive and heat
Plastic resin, through plastic colorant made of fine dispersion.That is, including pigment or fuel, carrier, dispersing agent in the Masterbatch
And additive, state, the carrier are selected as pet vector in an embodiment of the present invention, and the pigment is needed according to dyeing can
Selection phthalocyanine is red, phthalocyanine blue, phthalocyanine green, everbright fast red, macromolecular is red, macromolecular is yellow, permanent yellow, permanent violet, azophloxine, cadmium
Huang, titanium dioxide, carbon black, iron oxide red, one kind of iron oxide yellow or combinations thereof, the dispersing agent select polyethylene low-molecular-weight wax,
The additive needs to be changed according to customer demand.
The present invention provides the processing method of an anti-aging modified dacron, which comprises the following steps:
S1: PET is cut into pieces, weighs the parts by weight of 90-98, is placed in drying tower dry, the PET after being dried
Slice；
S2: the anti-aging master batch of 0.5-2 parts by weight and the Masterbatch of 1-8 parts by weight are taken, the PET is controlled and cuts
The number of piece, the anti-aging master batch and the Masterbatch and be 100:
S3: the obtained material of the step S1 and the step S2 is uniformly mixed, the screw extruder is added to；
And
S4: the PET, the anti-aging master batch and the Masterbatch heat in screw extruder, and melting squeezes out, warp
It is cooling after spinning machine extrusion forming, form POY silk thread.
In the step S1, the temperature control in the drying tower in the PET pre-crystallized stage is 176 DEG C, in drying
The temperature control in stage is 178 degrees Celsius, and the PET obtained under the drying condition is sliced functional.The anti-aging mother
Grain and the Masterbatch are precisely measured, and mix and be added to the spiral shell by entering in weight-loss type master batch machine after main feeder pipe
Bar extruder.
In the step S2, three kinds of raw materials are added in screw extruder simultaneously, and this mode improves terylene and adds
The processing efficiency of work.
In the step S3, the state modulator of the screw extruder is as follows:
