Description

Technical Field

[0001] This invention belongs to the field of fabric preparation technology, specifically relating to a carbon capture technology outdoor fabric and its preparation method. Background Technology

[0002] Carbon dioxide capture and storage (CCS) technology 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 industrial or related energy sources, transporting it to a storage site, and isolating it from the atmosphere for a long period. It includes three technical links: carbon capture, carbon transport, and carbon storage. Carbon dioxide captured through integrated refining and chemical processes is liquefied, purified, and hydrogenated to obtain green methanol. Green methanol is then used as a raw material to produce green ethylene glycol. Green ethylene glycol and terephthalic acid are used as monomers to form a long-chain polymer, namely polyethylene terephthalate (PET). The preparation technology roadmap is shown below. Figure 1 As shown. Carbon capture polyester PET is a downstream technology product of CCS technology. Like conventional polyester PET, carbon capture polyester PET can be used to produce polyester fibers through spinning technology for application in the textile industry. It uses captured carbon dioxide as a raw material to produce fibers, which has good environmental protection prospects.

[0003] Sugars are extracted from plants and fermented to obtain BIO-PDO. Using a suitable catalyst, BIO-PDO is polymerized with polymers (PTA, PTT, etc.) to produce a multifunctional, environmentally friendly fiber: DuPont Sorona bio-based fiber. This fiber exhibits better wrinkle recovery, tensile recovery, and dimensional stability, as well as enhanced breathability and moisture wicking properties. Blending it with polyester fibers can improve the poor breathability and lack of sweat absorption of polyester, thus enabling its better application in outdoor fabrics. However, both polyester and DuPont Sorona bio-based fibers are prone to static electricity. To further enhance their performance, the antistatic properties of the fabrics prepared from them need to be improved. Furthermore, outdoor fabrics also require certain waterproof and breathable / moisture-wicking properties. Therefore, this invention proposes a carbon-capture technology outdoor fabric and its preparation method. Summary of the Invention

[0017] As a further optimization of the present invention, the warp yarns in step (2) have a weaving density of 50-70 yarns / inch, the weft yarns have a weaving density of 45-60 yarns / inch, and the base fabric has a plain weave structure.

[0018] The beneficial effects of this invention are as follows:

[0024] The present application will now be described in further detail. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0025] I. Materials and Methods

[0026] Unless otherwise specified, all methods used in the following examples can be performed using conventional methods. Other materials and reagents used can be obtained commercially unless otherwise specified.

[0027] In the following embodiments, the carbon-capturing polyester yarn is prepared by melt blending carbon-capturing polyester chips with antistatic masterbatch, extruding the mixture through a spinneret, cooling it with a ring blower, bundling and oiling, stretching, heat setting, and winding to obtain carbon-capturing polyester fibers. These fibers are then processed through opening, carding, drawing, roving, spinning, and winding to obtain carbon-capturing polyester yarn with a fineness of 50–100D. The melt blending process conditions are generally adjusted depending on the raw material selection. In the following embodiments, the melt blending process conditions are uniformly selected as follows: melt blending spinning temperature 270℃, ring blower temperature 25℃, ring blower velocity 0.4 m / min, stretching ratio 2.4 times, stretching temperature 140℃, heat setting temperature 130℃, and winding speed 4000 m / min.

[0028] In the following embodiments, the preparation method of antistatic polyester masterbatch is as follows: the required raw materials are added to a high-speed mixer with a rotation speed of 1500 rpm and mixed at a mixing temperature of 180°C for 20 minutes. The mixed material is then added to a twin-screw extruder for melt blending. The melt temperature is controlled at 300°C and the screw speed is 300 rpm. The material is sheared and mixed by the twin-screw extruder for 15 minutes, and then extruded, cooled, pelletized, and dried to obtain the final product.

[0029] In the following embodiments, the carbon capture polyester fiber-DuPont Sorona bio-based fiber blended yarn is made from carbon capture polyester fiber and DuPont Sorona bio-based fiber as raw materials and spun by a ring spinning machine. The preferred blending mass ratio is 4:1, and the fineness is 50-100D.

[0030] In the following embodiments, the process of laminating a bio-based TPU film onto one side of the base fabric is as follows: First, the raw materials for the bio-based TPU film are mixed and then melt-extruded in a twin-screw extruder. The feed port temperature of the twin-screw extruder is 140-150°C, the zone 1 temperature is 160-170°C, the zone 2 temperature is 170-180°C, the zone 3 temperature is 190-195°C, the zone 4 temperature is 190-195°C, and the die head temperature is 185-190°C. Subsequently, the bio-based TPU granules are obtained by pelletizing using a pelletizer. Then, the base fabric is coated with PU adhesive using a coating machine. The bio-based TPU granules and the coated base fabric are then online cast and laminated on a casting machine to form a bio-based TPU film with a thickness of 0.1 mm. II.

[0046] The specific structure includes a base fabric and a bio-based TPU film laminated on one side of the base fabric. The base fabric is woven with carbon-capturing polyester yarn as the warp and carbon-capturing polyester fiber-DuPont Sorona bio-based fiber blended yarn as the weft. The specifications of both the carbon-capturing polyester yarn and the carbon-capturing polyester fiber-DuPont Sorona bio-based fiber blended yarn are 50D / 12F.

[0047] The carbon-capturing polyester yarn comprises, by weight percentage, 95% carbon-capturing polyester chips and 5% antistatic masterbatch, wherein the antistatic masterbatch comprises nickel cobalt oxide, polyethylene glycol, maleic anhydride and auxiliaries in a weight ratio of 2:10:1:1, and the auxiliaries are selected from phosphate coupling agents, hindered phenolic antioxidant 1010 and polyvinylpyrrolidone.

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

[0049] In the fabric preparation method, except that the warp yarn weaving density is 70 threads / inch and the weft yarn weaving density is 50 threads / inch, the other steps are the same as in Example 1.

[0050] The following performance tests were conducted on the fabrics prepared in Examples 1-3.

[0051] (1) Water repellency test: The test was conducted according to ISO 4920:2012 "Textile fabrics - Determination of water repellency of surface - Test for water repellency". 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 involves spraying the sample with distilled or deionized water. The sample is mounted on a retaining ring at a 45° angle to the horizontal plane, with the center of the sample below the nozzle. The water repellency rating is determined by comparing the appearance of the sample with the evaluation criteria and images. Ratings range from 0 to 5, where: 0 - both sides of the sample are completely wetted; 1 - the entire surface is wetted; 2 - half of the surface is wetted; 3 - only a small, discontinuous area of ​​the surface is wetted; 4 - the surface is not wetted, but small water droplets remain on the sprayed surface; 5 - the surface is not wetted and no water droplets remain on the sprayed surface. Rating 5 indicates the best water repellency.

[0053] (2) Hydrostatic pressure resistance test: The fabric was subjected to a hydrostatic pressure test according to GB / T 4744-2013. The test method was as follows: the test water on the clamping surface was wiped clean, the sample was clamped, and the front of the sample was in contact with the water. A continuously increasing water pressure was applied to the sample at a water pressure increase rate of 60 cm H2O / min, and the water seepage phenomenon was observed. During the pressure increase, when the third water droplet just appeared on the sample, the pressure increase was stopped, and the hydrostatic pressure value at this time was recorded.

[0054] (3) Moisture permeability test: According to national standard GB / T12704.1-2009(a), the moisture permeability of the samples was tested using an FX3180 moisture permeability measuring instrument. During the test, the temperature was 38℃, the humidity was 90.0%, the airflow velocity was 0.5m / s, and the test area was 28.27cm². 2 Before testing, the test chamber needs to be pre-conditioned for humidity. After automatic humidity conditioning, the instrument begins the moisture permeability test, automatically recording moisture permeability data every hour for a total of two times. After the experiment is completed, the moisture permeability data of the samples are manually recorded, and the average of the five sets of experimental data for each sample is used as the final data.

[0055] A fabric sample obtained by laminating a bio-based TPU film (the composition of the bio-based TPU film is the same as in Example 1) with 100% polyester fiber as control group 1 was subjected to the same tests as described above.

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

[0057] Table 1. Results of Fabric Performance Tests

[0058]

[0059]

[0060] As can be seen from Table 1, the fabrics prepared in Examples 1-3 all exhibit excellent waterproof and breathable properties, slightly better than the control group. The water repellency rating of the fabrics prepared in Examples 1-3 reaches level 4, the hydrostatic pressure resistance exceeds 9000 mmH2O, and the breathability reaches 9000 g / (m²). 2 With a lifespan of 24 hours or more, it meets the requirements of outdoor sports and gives the fabric good outdoor performance.

[0061] Since both carbon-capturing polyester yarn and DuPont Sorona bio-based yarn have the drawback of being prone to static electricity, this invention has explored the following optimization of the composition of carbon-capturing polyester yarn, adjusting the composition of the antistatic masterbatch according to Table 2.

[0062] Table 2. Composition of Antistatic Masterbatch

[0063]

[0064] In Table 2, the additives used in each group were phosphate coupling agent, hindered phenolic antioxidant 1010, and polyvinylpyrrolidone.

[0065] Fabric AF was prepared according to the composition of the antistatic masterbatch given in Table 2, with the remaining preparation steps and conditions the same as in Example 1. A fabric composed of 100% polyester fiber was used as control group 2.

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

[0067] The results are shown in Table 3.

[0068] Table 3. Results of Antistatic Performance Test of Fabric

[0069]

[0070]

[0071] Table 3 shows that adjusting the composition of the antistatic masterbatch can improve the antistatic properties of the fabric. Comparing Example 1 with fabric A, it can be seen that the improvement in fabric antistatic performance is directly proportional to the amount of binary metal oxide added. Comparing Example 1 with fabrics BC, it can be seen that nickel molybdate, cobalt molybdate, and nickel cobaltate all improve the antistatic performance of the fabric. Comparing Example 1 with fabrics DE, it can be seen that monometallic oxides are less effective than binary metal oxides in improving fabric antistatic performance. Comparing control group 1 with control group 2, it can be seen that the bio-based TPU film provided by this invention also has a positive effect on improving the antistatic performance of the fabric.

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

[0073] Table 4. Composition of Bio-based TPU Film

[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 laminated onto one side of a fabric composed of 100% polyester fiber using the lamination method given above to prepare a test fabric ae, and an uncoated fabric composed of 100% polyester fiber was used as a blank control group.

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

[0077] Table 5. Results of Antistatic Performance Tests on Fabrics

[0078]

[0079] As shown in Table 5, compared with fabric a, the addition of germanium stone powder can improve the antistatic ability of the fabric to a certain extent. Compared with fabric a, the difference between the two is that nano calcium carbonate is omitted in the composition of the bio-based TPU film of fabric c, which shows that it has a negative impact on the antistatic ability of the fabric.

[0080] Comparing fabrics a and d, it can be seen that omitting germanium powder increases the amount of ethylene-vinyl acetate copolymer, negatively impacting the fabric's antistatic properties. Comparing fabrics a and e, it can be seen that germanium powder, compared to the traditional inorganic filler talc, enhances the fabric's antistatic properties.

[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℃, the clamp spacing was 64mm, and the upper and lower clamps separated at a rate of 500mm / min. The tensile strength, elongation at break, and tear strength of the bio-based TPU film ae were determined. The average of five sets of experimental data for each sample was used as the final data. The results are shown in Table 6.

[0082] Table 6. Mechanical property test results of bio-based TPU film

[0083]

[0084]

[0085] Table 6 shows that, compared to bio-based TPU film e, the appropriate addition of germanium powder to the composition of bio-based TPU film a has a positive effect on improving the mechanical properties of the film. Bio-based TPU film b, compared to bio-based TPU film a, differs in that it omits germanium powder and correspondingly increases the amount of nano-calcium carbonate. The results show that the mechanical properties of bio-based TPU film b are somewhat reduced. Similarly, bio-based TPU film c, compared to bio-based TPU film a, differs in that it omits nano-calcium carbonate and correspondingly increases the amount of nano-calcium carbonate. The results show that the mechanical properties of bio-based TPU film c are significantly reduced. The introduction of appropriate amounts of nano-calcium carbonate, ethylene-vinyl acetate copolymer, and germanium powder forms a stable organic-inorganic compatible system, which is of positive significance in improving the shortcomings of bio-based TPU particles in terms of mechanical properties.

[0086] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
