Embodiment 1

[0038] A kind of bio-based nylon particle provided in this embodiment is made according to the following steps:

[0039] The cad A gene in Escherichia coli was amplified by PCR, then connected into pUC18, the plasmid was transferred into the host strain Escherichia coli JM109, and the transformant was selected by kanamycin;

[0040] The E.coli JM109pcad A strain is cultured in the culture medium, the seed liquid is inserted into the culture medium, and cultured in a fermenter;

[0041] After cultivation, the culture is transferred to a fermenter to continue the cultivation. After the cultivation, IPTG is added to induce, and then the cultivation is continued; after the cultivation, the bacteria are collected by centrifugation, and the wet bacteria can be obtained, and then the substrate and the wet bacteria are added to the reaction The conversion reaction is carried out in the container, and petroleum-based adipic acid is continuously added to it;

[0042] The reaction solut...

Embodiment 2

[0046] A kind of bio-based nylon particle provided in this embodiment is made according to the following steps:

[0047] Removing the cell components in the fermentation broth, alkalizing the fermentation broth to pH>11;

[0048] Heating the fermentation broth to 90-110°C to hydrolyze the acetyl-DAP;

[0049] Heating the fermentation broth to 135°C, and extracting with a dipolar protic organic solvent;

[0050] Remove cells from industrial fermentation broth through separation, flocculation, and filtration, and then add sodium hydroxide to adjust pH>12;

[0051] Heating the fermentation broth for hydrolysis, then extracting with n-butanol to obtain crude pentamethylenediamine, and purifying by acid precipitation or distillation;

[0052] The purified pentamethylenediamine is polymerized with petroleum-based adipic acid, and the product is dried and pelletized to obtain bio-based nylon particles.

Embodiment 3

[0054] Using the bio-based nylon particles obtained in Example 1 as a raw material, the bio-based nylon fabric was prepared according to the following steps:

[0055] S1. Heat 10.5kg of bio-based nylon particles, 0.5kg of antioxidant DTBHQ, and 1kg of phosphorus-nitrogen flame retardant until melted and mix and stir evenly;

[0056] S2. Add 2.5 kg of 5 μm bamboo fiber powder and 3.5 kg of 15 μm corn fiber powder, ultrasonically disperse evenly and soak for 30 minutes, filter and dry at room temperature for 12 hours to obtain a mixture;

[0057] S3, putting the mixture into a screw extruder to melt at 230°C, and then spinning at 270°C and then cooling to obtain the primary product;

[0058] S4. The cooled primary product is then oiled, stretched, and wound to obtain a finished product.

Abstract

The invention discloses a bio-based nylon fabric and relates to the textile field. The bio-based nylon fabric is prepared from the following components in parts by weight: 105-120 parts of bio-basednylon particles, 25-35 parts of bamboo fiber powder, 35-45 parts of corn fiber powder, 5-8 parts of an environment-friendly anti-oxidant agent and 10-15 parts of an environment-friendly flame retardant; the bio-based nylon particles are polymerized from bio-based pentamethylene diamine and petroleum-based adipic acid; the bamboo fiber powder is powder with a grain size of 5-15 mu m, formed by grinding bamboo fibers; and the corn fiber powder is powder with a grain size of 15-20 mu m, formed by grinding corn fibers. The bio-based nylon fabric has performances such as water absorption, softnessand wear resistance. The bio-based nylon fabric can be used for producing knitted underwear and clothing fabric. The bio-based nylon fabric takes bio-based nylon as a raw material, can be regenerated,is environment-friendly, is rich in raw material resource, and has many excellent performances.

Description

technical field [0001] The invention relates to the field of textiles, in particular to a bio-based nylon fabric and a preparation process thereof. Background technique [0002] The research on polyamide fiber began in the late 1930s. It is the earliest synthetic fiber in the world to achieve industrial production. The fiber was first used in the textile field as silk stockings. Its fine monofilament and high strength made this product all the rage. Subsequently, polyamide fibers were applied to military products such as parachutes and military uniforms, as well as clothing, carpets, fishing nets and other fields. Bio-based materials are new materials that use renewable materials such as straw and other agricultural and forestry wastes, biogas, biodiesel, bioplastics, etc. as raw materials for biological, physical or chemical treatment. The characteristics of environmental protection and recyclability of biology and materials meet the contemporary requirements for the ecolo...
