Embodiment 1-8

[0035] One, the preparation of embodiment 1-8 plant source PET masterbatch

[0036] All plant extract powders are commercially available, and 99.5% of the powder must pass through a 10,000-mesh sieve; the powder is loose in appearance, without agglomeration, and has no visible impurities; the color has the inherent color of the plant, and is uniform; the smell is uniform; Moisture ≤ 5%; total bacterial colony < 1000cfu / g, Salmonella and Escherichia coli cannot be detected.

Embodiment 1

[0037] Embodiment 1 A kind of preparation of lavender PET masterbatch

[0038] Mix 50 parts of lavender extract powder, 15 parts of chitin and 4 parts of starch, add 50 parts of deionized water, adjust the pH to 7 with sodium carbonate, heat to 45-70°C and mix well, shake the resultant and decompress Distill for 0.5-1h, then dissolve in 40 parts of deionized water, filter through a semi-permeable membrane for 0.8h, add 10 parts of acrylic acid to the filtered film, put it into a banbury mixer for 1.1h. The product obtained after banburying is dried and pulverized to obtain modified lavender extract. The prepared modified lavender extract has good compatibility and the mesh number is 10000 mesh.

[0039] Add 4 parts of reaction aids in 160 parts of modified lavender extracts, stir with the speed of 1800rad / min. 840 parts of PET slices were melted and stirred, then added modified lavender extract containing reaction aids, 0.16 parts of EBS P-200, 0.164 parts of tourmaline powd...

Abstract

The invention relates to a plant-derived PET master batch and a product prepared from the same. According to the invention, anti-carbonization additives including chitin and starch are added into a plant extract, and a modified plant extract is obtained after internal mixing of an internal mixer, so that carbonization in a high-temperature melting process is reduced, and the components of the plant extract are not lost; PET slices and the modified plant extract are blended and melted to prepare plant-derived PET master batch, wherein the master batch is uniform in particle size; and after fiber spinning, film making, bottle blowing or plastic making, the product has fragrance, is helpful for releasing negative ions, and has antibacterial performance, and the moisture regain of fibers is improved.

Description

technical field [0001] The invention relates to the technical field of PET, in particular to a plant-derived PET masterbatch and a preparation method and application thereof. Background technique [0002] PET (polyethylene terephthalate) has good optical properties and weather resistance, and the products made have the advantages of good transparency, light weight and high strength. For example, polyester fiber made of PET, also known as polyester fiber, has the characteristics of high strength, high modulus and low water absorption. As one of the three main fibers in synthetic fibers, polyester fiber is widely used in clothing, curtains, curtains, bedding, interior decoration and various special materials. Polyester fabric has the advantages of good drapability, wrinkle resistance, pleat retention, dimensional stability, abrasion resistance and easy washability and wearability. In order to further improve the wearing comfort of polyester fibers and increase the added valu...
