experiment example 1

[0039] Experimental Example 1: Masterbatch Preparation

[0040] In this experimental example, the photochromic masterbatch, antioxidant masterbatch, ultraviolet absorber masterbatch and light stabilizer masterbatch were prepared according to the masterbatch formula in Table 1 below.

[0041] Table I

[0042]

[0043] Note 1: The units are parts by weight or parts by weight

[0044] Note 2: The photochromic agent is the model NCC#12 purchased from Chongyu Technology, which has the structure of general formula (I-10)

[0045] Note 3: The antioxidant is the model Revonox 608 purchased from Qitai Technology

[0046] Note 4: The dispersant is the model D1377E purchased from EMS-Griltex

[0047] Note 5: The ultraviolet light absorber is purchased from Yongguang Chemical Eversorb 41FD

[0048] Note 6: Light stabilizer is purchased from Yongguang Chemical Eversorb 94FD

experiment example 2

[0049] Experimental Example 2: Prepare photochromic polypropylene fiber and perform property test

[0050] In this experimental example, different combinations of ultraviolet light absorbers and light stabilizers and different ratios between the components were selected to prepare various photochromic polypropylene fibers as shown in Table 2 below. The fiber mechanical properties of these photochromic polypropylene fibers all have good spinning efficiency after testing.

[0053] Note 1: The units in the composition formula are parts by weight

[0054] Note 2: The photochromic agent is the model NCC#12 purchased from Chongyu Technology, which has the structure of general formula (I-10)

[0055] Note 3: The first UV absorber is Eversorb 12 purchased from Yongguang Chemical

[0056] Note 4: The second UV absorber is Eversorb 41FD purchased from Yongguang Chemical

[0057] Note 5: The first photostabilizer is Eversorb 90 purchased from Yongguang C...

experiment example 3

[0060] Experimental Example 3: Ultraviolet Light Illumination Test

[0061] In this experimental example, ultraviolet light is used to irradiate these photochromic polypropylene fibers, and the discoloration effect and L*a*b* color space properties are shown in Table 3.

[0062] Table three

[0063]

[0064] Note 1: L* stands for brightness

[0065] Note 2: a* represents the opposite dimension of color, if the value of a* is positive (+), it means that the tested sample is reddish; if the value of a* is negative (-), it means that the tested sample is greenish

[0066] Note 3: b* represents the opposite dimension of color, if the value of b* is positive (+), it means that the tested sample is yellowish; if the value of b* is negative (-), it means that the tested sample is blue

[0067] Note 4: ◎ means excellent discoloration; △ means poor discoloration; X means no discoloration

[0068] It can be seen from Table 3 that the difference between Comparative Example 1 and Co...

Abstract

A photochromic polypropylene fiber is provided. The photochromic polypropylene fiber includes about 98 to 99 parts by weight of polypropylene, about 0.2 to 0.8 parts by weight of a photochromic agent, about 0.1 to 1 parts by weight of an ultraviolet absorber, and about 0.1 to 1 parts by weight of a light stabilizer. The ultraviolet absorber includes the light stabilizer and n is 10-14. A preparation method of the photochromic polypropylene fiber is further provided.

Description

technical field [0001] The present invention relates to a textile material, and in particular relates to a photochromic polypropylene fiber and a preparation method of the photochromic polypropylene fiber. Background technique [0002] Under the trend of globalization, the textile industry is facing strong competitive pressure. The textile industry must constantly develop new technologies and diversified products in order to face global competition. [0003] Photochromic fibers are fibers that automatically change color when stimulated by light. Photochromic fibers can produce discoloration under the irradiation of light of a certain wavelength, and will reversibly change back to the original color under the irradiation of light of another wavelength (or heat). Photochromic fibers are mainly used in entertainment clothing, safety clothing, decorations and anti-counterfeiting marks, etc. However, the existing preparation methods are quite complicated, and the produced photo...
