Description

Technical Field

[0001] The present invention belongs to the technical field of fabric preparation, and specifically relates to a carbon capture technology outdoor fabric and a preparation method thereof. Background Art

[0002] Carbon dioxide capture and storage (CCS) is one of the important ways to achieve greenhouse gas emission reduction and has good development prospects. CCS technology refers to the process of separating carbon dioxide from the source of industry or related energy, transporting it to a storage site, and isolating it from the atmosphere for a long time. It includes three technical links: carbon capture, carbon transportation, and carbon storage. Carbon dioxide captured from integrated refining and chemical industries is liquefied, purified, hydrogenated, and other steps to obtain green methanol. Green methanol is used as a raw material to further produce green ethylene glycol. Green ethylene glycol and terephthalic acid are used as polymerization monomers to form long-chain polymers through polymerization reactions, namely polyethylene terephthalate (commonly known as polyester PET). The preparation technology roadmap is as follows: Figure 1 As shown. Carbon capture polyester PET is a downstream technical product of CCS technology. Carbon capture polyester PET is consistent with conventional polyester PET. Both can be used in the textile field to obtain polyester fibers through spinning technology. The captured carbon dioxide is used as a raw material to produce fibers, which has a good environmental protection prospect.

[0003] Sugar is extracted from plants, and the product BIO-PDO is obtained after fermentation. A suitable catalyst is selected to polymerize BIO-PDO with a polymer compound (PTA, PTT, etc.) to obtain a multifunctional fiber with environmentally friendly materials, namely DuPont Sorona bio-based fiber. The fiber has better wrinkle recovery, stretch recovery, dimensional stability, stronger air permeability, moisture absorption and perspiration wicking, and blending with polyester fiber can improve the shortcomings of poor air permeability and non-perspiration of polyester fiber, and thus can be better applied to the field of outdoor fabrics. However, both polyester fiber and DuPont Sorona bio-based fiber have the disadvantage of being easy to generate static electricity. In order to better improve the application performance of the two, it is also necessary to improve the antistatic ability of the fabrics prepared by the two. In addition, for outdoor fabrics, it is also necessary to meet certain waterproof properties and air permeability and moisture permeability. In this regard, the present invention proposes a carbon capture technology outdoor fabric and a preparation method thereof. Summary of the invention

[0044] Example 3

[0045] The carbon capture technology outdoor fabric provided in this embodiment comprises, by weight percentage, 70% carbon capture polyester fiber and 30% DuPont Sorona bio-based fiber.

[0046] The specific structure includes a base fabric and a bio-based TPU film composited on one side of the base fabric.

The antistatic masterbatch comprises nickel cobaltate, polyethylene glycol, maleic anhydride and additives in a mass ratio of 2:10:1:1.

[0048] The bio-based TPU film comprises, by weight percentage, 85% of bio-based TPU particles, 10% of ethylene-vinyl acetate copolymer, 3% of nano calcium carbonate and 2% of germanium stone powder.

[0049] In the method for preparing the fabric, except that the weaving density of the warp yarn is 70 yarns / inch and the weaving density of the weft yarn is 50 yarns / inch, the remaining steps are the same as those in Example 1.

[0050] The fabrics prepared in Examples 1-3 were subjected to the following wearing performance tests.

[0051] (1) Water repellency test: The test was conducted according to ISO 4920:2012 "Determination of the resistance of textile fabrics to water splashing". In addition, a commercially available 100% wool fabric (yarn count of 80, yarn twist of 1000 twists / m, S twist) was used as a control group and subjected to the same test treatment as above.

[0052] The test method is to spray the sample with distilled or deionized water. The sample is mounted on a retaining ring and placed at a 45° angle to the horizontal plane, with the center of the sample located below the nozzle. The water level is assessed by comparing the appearance of the sample with the assessment criteria and pictures. The levels range from 0 to 5, where 0-both sides of the sample are completely wetted; 1-the entire surface of the sprayed surface is wetted; 2-half of the sprayed surface is wetted; 3-only a small discontinuous area of ​​the sprayed surface is wetted; 4-the sprayed surface is not wetted, but there are small water droplets on the sprayed surface; 5-the sprayed surface is not wetted, and there are no small water droplets on the sprayed surface. Level 5 indicates the best waterproof performance.

[0053] (2) Hydrostatic pressure resistance test: The fabric was subjected to a hydrostatic pressure resistance test in accordance with GB / T 4744-2013. The test method is as follows: Wipe off the experimental water on the clamping surface, clamp the sample, and make the front of the sample contact the water. Apply a continuously increasing water pressure to the sample at a water pressure increase rate of 60cm H2O / min, and observe the water seepage phenomenon. During the pressure increase process, stop increasing the pressure when the third water droplet appears on the sample, and record the hydrostatic pressure value at this time.

[0054] (3) Moisture permeability test: According to the national standard GB / T12704.1-2009 (a), the moisture permeability of the sample was tested using the FX3180 moisture permeability measuring instrument. During the test, the temperature was 38°C, the humidity was 90.0%, the air flow rate was 0.5m / s, and the test area was 28.27cm 2 Before the test, the test chamber needs to be pre-humidified. After the automatic humidity adjustment is completed, the instrument starts the moisture permeability test and automatically records the moisture permeability data once every hour, twice in total. After the experiment is completed, the moisture permeability data of the sample is manually recorded, and the average of 5 groups of experimental data for each group of samples is used as the final data.

[0055] A fabric sample made of 100% polyester fiber and composited with a bio-based TPU film on one side (the composition of the bio-based TPU film is the same as that of Example 1) was used as control group 1 and subjected to the same test as above.

[0056] The test results are shown in Table 1.

[0057] Table 1. Fabric wearing performance test results

[0058]

[0059]

[0060] It can be seen from Table 1 that the fabrics prepared in Examples 1-3 all have excellent waterproof and moisture permeability, which is slightly better than that of the control group. The water repellency level of the fabrics prepared in Examples 1-3 can reach level 4, the hydrostatic pressure resistance value reaches more than 9000 mmH2O, and the moisture permeability reaches 9000 g / (m 2 ·24h) or more, which can meet the requirements of outdoor sports and give the fabric better outdoor performance.

[0061] Since both carbon capture polyester yarn and DuPont Sorona bio-based yarn have the disadvantage of being prone to generating static electricity, the present invention optimizes the composition of the carbon capture polyester yarn as follows, and adjusts the composition of the antistatic masterbatch according to Table 2.

[0062] Table 2. Composition of antistatic masterbatch

[0063]

[0064] In Table 2, the additives selected for each group are phosphate coupling agent, hindered phenol antioxidant 1010 and polyvinyl pyrrolidone.

[0065] According to the composition of the antistatic masterbatch given in Table 2, fabric AF was prepared on the basis of the remaining preparation steps and conditions being the same as those in Example 1. A fabric containing 100% polyester fiber was used as control group 2.

[0066] The fabrics of Example 1, fabrics AF, and fabrics of control groups 1-2 were tested for antistatic properties according to GB / T 12703.1-2021 "Textiles-Test methods for electrostatic properties Part 1: Corona charging method", and the electrostatic voltage half-life was used as the test index (excellent: half-life ≤10s; good: 10<half-life ≤30; general: 30<half-life ≤60; poor:>60s).

[0067] The results are shown in Table 3.

[0068] Table 3. Test results of fabric antistatic properties

[0069]

[0070]

[0071] It can be seen from Table 3 that by adjusting the composition of the antistatic masterbatch, the fabric can obtain better antistatic ability. By comparing Example 1 with fabric A, it can be seen that the degree of improvement in the antistatic performance of the fabric is proportional to the amount of binary metal oxide added. By comparing Example 1 with fabric BC, it can be seen that when binary metal oxides are selected from nickel molybdate, cobalt molybdate, and nickel cobaltate, the antistatic performance of the fabric is improved. By comparing Example 1 with fabric DE, it can be seen that the effect of monometallic oxides on improving the antistatic performance of the fabric is not as good as that of binary metal oxides. By comparing control group 1 with control group 2, it can be seen that the bio-based TPU film provided by the present invention also has a positive effect on improving the antistatic performance of the fabric.

[0072] In order to further explore the influence of the composition of the bio-based TPU film on the performance of the fabric, based on the raw material ratio of the bio-based TPU film given in Example 1, the composition of the bio-based TPU film was adjusted according to Table 4.

[0073] Table 4. Composition of bio-based TPU films

[0074]

[0075] According to the composition of the bio-based TPU film given in Table 2, a bio-based TPU film ae was prepared. The bio-based TPU film ae was compounded on one side of a fabric composed of 100% polyester fiber according to the above-mentioned laminating method to prepare a test fabric ae, and a fabric composed of 100% polyester fiber without lamination was used as a blank control group.

[0076] Fabric ae and blank control were tested for antistatic performance according to GB / T 12703.1-2021 "Textiles-Test methods for electrostatic properties Part 1: Corona charging method", and the static voltage half-life was used as the test index (excellent: half-life ≤ 10s; good: 10 < half-life ≤ 30; general: 30 < half-life ≤ 60; poor: > 60s). The results are shown in Table 5.

[0077] Table 5. Test results of fabric antistatic properties

[0078]

[0079] It can be seen from Table 5 that, compared with fabric a and fabric b, the addition of germanium stone powder can improve the antistatic ability of the fabric to a certain extent. Compared with fabric a and fabric c, the difference between the two is that nano calcium carbonate is omitted in the composition of the bio-based TPU film of fabric c. From the results, it can be seen that it has a negative impact on the antistatic ability of the fabric.

[0080] Comparing fabric a and fabric d, it can be seen that omitting germanium stone powder corresponds to increasing the amount of ethylene-vinyl acetate copolymer, which has a negative impact on the antistatic ability of the fabric. Comparing fabric a and fabric e, it can be seen that germanium stone powder has the effect of improving the antistatic ability of the fabric compared with traditional inorganic filler talc.

[0081] Furthermore, the mechanical properties of the bio-based TPU film ae were measured according to GB / T 528-1998 standard. The test temperature was 23°C, the chuck spacing was 64 mm, and the upper and lower chucks were separated at a rate of 500 mm / min. The tensile strength, elongation at break and tear strength of the bio-based TPU film ae were measured. The average of 5 groups of experimental data was used as the final data for each group of samples. The results are shown in Table 6.

[0082] Table 6. Mechanical properties test results of bio-based TPU films

[0083]

[0084]

[0085] From Table 6, it can be seen that compared with bio-based TPU film e, the addition of germanium powder in the composition of bio-based TPU film has a positive effect on improving the mechanical properties of the film. Compared with bio-based TPU film a, bio-based TPU film b is different in that the germanium powder is omitted and the amount of nano-calcium carbonate is increased. From the results, it can be seen that the mechanical properties of bio-based TPU film b have decreased. Compared with bio-based TPU film a, the difference between bio-based TPU film c and bio-based TPU film a is that the amount of nano-calcium carbonate is omitted and the amount of nano-calcium carbonate is increased. From the results, it can be seen that the mechanical properties of bio-based TPU film c have decreased significantly. The introduction of appropriate amounts of nano-calcium carbonate, ethylene-vinyl acetate copolymer and germanium powder forms a stable organic-inorganic compatible system, which has a positive significance for improving the deficiencies in the mechanical properties of bio-based TPU particles.

[0086] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
