Example Embodiment

[0021]Example 1: A method of preparing a biodegradable cooling fabric, such asfigure 1 As shown, including the following steps:
[0022]S1, raw material selection:
[0023]The substrate is selected from the group consisting of polyester slice, and the biodegradable additive can be used EcoPure PET (G2), and the cooling additive is used as jade powder.
[0024]S2, dilution granulation of biodegradable additives:
[0025]The biodegradable additive and the polyester slice are mixed in the drum in a rotating drum according to the mass ratio of 1: 5, and then granulated by a twin screw granulator, and the dagger-degradable additive masterbatch is prepared.
[0026]S3, biodegradable cooling fibers, including the following steps:
[0027]The first work step: The substrate, the reducing biodegradable additive mother particles and the cooling additive are coated in the drum in the drum in the drum in the drum in the drum.
[0028]Second step: The dry mixture is then moltered extruded by the screw extruder, pressurized to 10-14 MPa, and then instantaneously discharged into the spinning box. 7MPa pressure, finally spinning the spinning assembly and the circular spline plate, wound into a bucket to obtain a front spun beam. After the pressurization and instantaneous pressure failure step, the fibers are formed to form a multi-microporous passage in the fibers, increasing the specific surface area of ​​the fibers, thereby improving the moisture absorption of the fiber, and can be used to enter the fiber in the fiber, which is also Improve the rate of degradation of fibers.
[0029]Third Step: The spunning forward silk bundle is balanced 24-48 hours, enters the rear textile drafting process, and then roll the drafted wire beam, and then relaxed in the oven, resulting Biode can degrade cool polyester short fibers.
[0030]S4, spinning:
[0031]Biodegradable cool polyester short fibers are made of 26S tight spun organisms to degrade cool polyester yarns after taking cotton, comb, combing, and strip, roving, and fine gauze.
[0032]S5, woven:
[0033]Equipment: The number of single-sided amenities in Myese is 28G.
[0034]Fabric tissue structure: single beaded mesh.
[0035]Yar length: 27.5 cm / 100n.
[0036]S6, dyeing, including the following steps:
[0037]1, the front treatment process: first add oil and refining agent to 98 ° C at a rate of 2 ° C / min, after 30 min, heat at 75 ° C in 75 ° C, then wash 2 at the rate of 2 ° C / min Wash the glacial acetic acid;
[0038]2, the dyeing process: adding a mossifying agent, glacial acetic acid, adjusting the pH to 3.7-4.2, and the dye is adjusted to 90 ° C in 2-3 ° C / min, then heat up at 1 ° C / min. It was 30 min at 130 ° C and then cooled to 70 ° C in a 2 ° C / min.
[0039]3, the post-treatment process: after the dye is completed, the reduction washing, and the cleaning is washed.
[0040]S7, dehydration:
[0041]The dye rear material was dehydrated, the dehydration speed was 400 R / min, and the dehydration time was 2 min.
[0042]S8, type:
[0043]After the dehydrated fabric is fixed, the hyphenic sweating is added 2%, the type temperature is 130 ° C, and the type of the stereotype is 20 m / min, and the single beaded mesh organism can degrade the cool fabric.

Example Embodiment

[0044]Example 2: A method of preparing a biodegradable cooling fabric, different steps with Example 1 is:
[0045]S5, woven:
[0046]Equipment: The number of single-sided amenities in Myese is 28G.
[0047]Fabric tissue structure: single beaded mesh.
[0048]Yar length: 26.5 cm / 100n.
[0049]S6, dyeing, including the following steps:
[0050]1, the front treatment process: first add oil and refining agent to 98 ° C at a rate of 2 ° C / min, after 30 min, heat at 75 ° C in 75 ° C, then wash 2 at the rate of 2 ° C / min Wash the glacial acetic acid;
[0051]2, the dyeing process: adding a mossifying agent, glacial acetic acid, adjusting the pH to 3.7-4.2, and the dye is adjusted to 90 ° C in 2-3 ° C / min, then heat up at 1 ° C / min. It was allowed to heat at 130 ° C for 35 min, followed by watering to 70 ° C at 2 ° C / min.
[0052]3, the post-treatment process: after the dye is completed, the reduction washing, and the cleaning is washed.
[0053]S7, dehydration:
[0054]The dye rear fabric was dehydrated, and the dehydration speed was 300 r / min, and the dehydration time was 3 min.
[0055]S8, type:
[0056]After the dehydrated fabric is fixed, it is 2% 2% of the hygroscopic sweating, and the type temperature is 145 ° C, and the type speed is 25 m / min, and the single-beaded mesh organism can degrade the cool fabric.

Example Embodiment

[0057]Example 3: A method of preparing a biodegradable cooling fabric, different steps from Example 1 in:
[0058]S5, woven:

[0060]Fabric tissue structure: single beaded mesh.
[0061]Yar length: 26.5 cm / 100n.
[0062]S6, dyeing, including the following steps:
[0063]1, the front treatment process: first add oil and refining agent to 98 ° C at a rate of 2 ° C / min, after 30 min, heat at 75 ° C in 75 ° C, then wash 2 at the rate of 2 ° C / min Wash the glacial acetic acid;
[0064]2, the dyeing process: adding a mossifying agent, glacial acetic acid, adjusting the pH to 3.7-4.2, and the dye is adjusted to 90 ° C in 2-3 ° C / min, then heat up at 1 ° C / min. It was 40 min at 130 ° C and then cooled to 70 ° C at 2 ° C / min.
[0065]3, the post-treatment process: after the dye is completed, the reduction washing, and the cleaning is washed.
