Description

Technical Field

[0001] The invention relates to a nylon filament, and more particularly to an anti-ultraviolet skin-care type nylon filament and a preparation method thereof. Background Art

[0002] Nylon fiber is one of the earliest synthetic fibers. Due to its excellent physical and mechanical properties and good textile processability, its output ranked first among synthetic fibers for a long time. However, due to price and production cost restrictions and the rapid development of polyester fiber, it has now become the second largest synthetic fiber in terms of output.

[0003] Currently, there are various anti-UV sunscreen products. The sunscreen methods in the textile field are mainly divided into auxiliary sunscreen, raw yarn sunscreen, physical sunscreen, and coating sunscreen. Physical sunscreen is achieved through fabric thickness, style design, etc. It is usually not thin enough, has poor sunscreen performance, and is generally comfortable to wear. Coating sunscreen has excellent sunscreen performance and is suitable for extreme outdoor climates, but it has poor air permeability and moisture permeability, and feels hard; and conventional raw yarn sunscreen mostly obtains sunscreen effects by blocking ultraviolet rays, but by blocking each wavelength of light, it is also possible to block the light in the beneficial wavelength range, which is not good for skin health and does not achieve the real sunscreen purpose.

The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0019] Embodiment 1, an anti-ultraviolet skin-care nylon filament, comprising nylon and a functional masterbatch mixed with each other, wherein the functional masterbatch is formed by mixing a Porphyridium cruentum extract, a Spirulina platensis extract and an inorganic fluorescent body;

[0020] A method for preparing anti-ultraviolet skin-care nylon filament comprises the following steps:

[0021] Step 1, extracting, grinding and refining Porphyridium cruentum to obtain a Porphyridium cruentum extract, using a Porphyridium cruentum extract, the B phycoerythrin contained in the extract has a peak wavelength at 305nm in the absorption spectrum, and the emission spectrum has peak wavelengths at 570nm and 610nm; extracting, grinding and refining Spirulina platensis to obtain a Porphyridium cruentum extract, Spirulina platensis extract, the phycocyanin component in the extract has a peak wavelength at 350nm in the absorption spectrum, and the emission spectrum has peak wavelengths at 640nm and 700nm; ZnO is doped with a sulfur-containing compound and then calcined to obtain a zinc oxide phosphor, the absorption spectrum has a peak wavelength at 365nm, and the emission spectrum has a peak wavelength at 510nm, the obtained Porphyridium cruentum extract No. 2 Spirulina platensis extract and the prepared zinc oxide phosphor are mixed and dissolved in water at a weight ratio of 2:2:6 to form a composition;

[0022] Step 2, oscillating in an oscillating wall-breaking pulverizer, vacuum drying, and preparing a nano-scale powder composition, using low-viscosity nylon slices as a matrix, taking 20 parts by weight of the prepared composition powder, and 80 parts by weight of low-viscosity nylon, and appropriately adding conventional amounts of antioxidants and dispersants, after fully mixing, preparing functional masterbatches through a screw extruder; in the manufacturing process, the masterbatch is prepared by melt plasticization, and the temperature of each temperature zone of melt plasticization is controlled at 210°C in the first temperature zone; 220°C in the second temperature zone; 235°C in the third temperature zone; and 250°C in the fourth temperature zone; The temperature of the fifth temperature zone is 235°C; the temperature of the sixth temperature zone is 215°C; the temperature of the seventh, eighth and ninth temperature zones is 210°C; the temperature of the head temperature zone is 230°C, screw shearing (the main engine speed of the screw shearing is 590r / min), water-cooled pelletizing (the main engine speed of the pelletizer is 950r / min), vibration screening (double-layer screen with an upper screen diameter of 6mm and a lower screen diameter of 3mm), vacuum drying and a series of process technologies are used to prepare the functional masterbatch; the final functional masterbatch slices prepared have a diameter of 2-4mm, a length of 2.5-5mm, and a moisture content of less than 0.08%;

[0023] Step 3, two-component masterbatch adding machine feeding (the prepared functional masterbatch is taken in 15 parts, the nylon slice is taken in 85 parts by weight, and they are added from different feed heads for full mixing) → storage tank (with stirring paddle and material level detection function, which has the effect of mixing slices and masterbatch) → screw extruder (the temperature of each section temperature zone is controlled in the first section temperature zone at 230℃; the temperature of the second section temperature zone is 240℃; the temperature of the third section temperature zone is 262℃; the temperature of the fourth section temperature zone is 261℃; the temperature of the fifth section temperature zone is 261℃; the temperature of the sixth section temperature zone is 260℃) → melt distribution pipeline → metering pump → spinning Fiber assembly (single-cavity double-jet spinneret, specification is Φ104mm; single-cavity single-jet spinneret, specification is Φ66mm) → monomer suction → side blowing (wind speed 0.5m / s) → bundling point → moistening and oiling (oil agent mass fraction 12%) → corridor → wire guide rod → 1 guide plate (roller) → main network device (for blowing knots) → 2 guide plates (rollers) → winding wire guide hook → winding head (winding speed 4500m / min) → winding into the final nylon filament with a specification of 40D / 48F. The mixture is added to a nylon high-speed spinning machine for spinning and winding to complete the preparation of the overall nylon filament.

[0024] By providing a composition with a wavelength conversion substance, the wavelength conversion substance converts the wavelength of ultraviolet rays contained in the incident light and emits light having a longer wavelength than the wavelength of the ultraviolet rays. The composition is a composition for external use on the skin and is a composition for activating the skin by irradiating the skin with light containing ultraviolet rays, effectively utilizing the ultraviolet rays and emitting light that has a good effect on the skin, thereby achieving the effect of sun protection and skin care.

[0025] Conventional raw yarn sunscreen mostly achieves sunscreen effect by blocking ultraviolet rays, but by blocking each wavelength of light, it is also possible to block the light in the beneficial wavelength range, which is not good for skin health and does not achieve the real sunscreen purpose. The prepared nylon filament, through material screening, organic algae protein with ultraviolet conversion function and inorganic fluorescent material are blended in a certain proportion to prepare a functional masterbatch that can effectively convert ultraviolet rays into beneficial light waves, and further prepared into nylon functional filament that can be used to produce fabrics, which can effectively convert ultraviolet rays into yarns in the beneficial wavelength range. Such yarns are used to prepare summer skin-friendly clothing, which is more comfortable to use and has better anti-ultraviolet effect.

[0026] The difference between Comparative Example 1 and Example 1 is that in step 1, the Porphyridium cruentum extract, Spirulina platensis extract and zinc oxide phosphor in Example 1 are mixed in a weight ratio of 4:2:4, and other process parameters and processing conditions remain unchanged.

[0027] The difference between Comparative Example 2 and Example 1 is that in step 1, the Porphyridium cruentum extract, Spirulina platensis extract and zinc oxide phosphor in Example 1 are mixed in a weight ratio of 5:3:2, and other process parameters and processing conditions remain unchanged.

[0028] Example 2 differs from Example 1 in that: in step 1, the zinc oxide phosphor in Example 1 is replaced with a magnesium titanate phosphor, the absorption spectrum of the magnesium titanate phosphor has a peak wavelength at 365 nm, and the emission spectrum has a peak wavelength in the frequency band of 660 to 680 nm, the Porphyridium cruentum extract, the Spirulina platensis extract and the magnesium titanate phosphor are mixed in a weight ratio of 2:2:6, and other process parameters and processing conditions remain unchanged.

[0029] Example 3 differs from Example 1 in that: in step 1, magnesium titanate phosphor is also added while zinc oxide phosphor is added, and the Porphyridium cruentum extract, Spirulina platensis extract, zinc oxide phosphor and magnesium titanate phosphor are mixed in a weight ratio of 2:2:3:3, and other process parameters and processing conditions remain unchanged.

[0030] Comparative Example 3 is different from Example 1 in that: in step 3, the weight portion of the functional masterbatch in Example 1 is adjusted to 8, the weight portion of the nylon slice is adjusted to 92, and other process parameters and processing conditions remain unchanged.

[0031] Example 4 is different from Example 1 in that: in step 3, the weight portion of the functional masterbatch in Example 1 is adjusted to 30, the weight portion of the nylon slice is adjusted to 70, and the other process parameters and processing conditions remain unchanged.

[0032] The following physical properties were obtained by testing the nylon filaments prepared as above:

[0033]

[0034] The anti-ultraviolet related properties of the prepared nylon filaments were measured and the data obtained were as follows:

[0035]

[0036]

[0037] The reference standard for the anti-ultraviolet performance test is GB / T 18830-2009 "Evaluation of the anti-ultraviolet performance of textiles"; the reference standard for the far-infrared performance test is GB / T 30127-2013 "Testing and evaluating the far-infrared performance of textiles"; the reference standard for the instantaneous cool feeling test is GB / T 35263-2017 "Testing and evaluating the instantaneous cool feeling of textiles"

[0038] From the above experimental data, it can be concluded that

[0039] By comparing Example 1, Comparative Example 1 and Comparative Example 2, it can be concluded that the optimal weight ratio of Porphyridium cruentum extract, Spirulina platensis extract and inorganic phosphor is 2:2:6. When the weight ratio of inorganic phosphor decreases, the anti-ultraviolet performance UPF decreases, which increases the UVA transmittance and reduces the anti-ultraviolet effect.

[0040] By comparing Example 1, Example 2, and Example 3, it can be concluded that when the inorganic phosphor is zinc oxide phosphor, the effect is greater than that of magnesium titanate phosphor.

[0041] By comparing Example 1, Example 4 and Comparative Example 3, it can be concluded that when the number of functional masterbatches is reduced, the anti-ultraviolet effect is significantly reduced.

[0042] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
