Problems solved by technology

However, in actual use, it was found that the boards for interior parts made of hemp fiber had a strong smell, and the test results could not meet the requirements of customers. The main source of the smell was hemp fiber, especially when the hemp fiber was damp, the smell became more pungent
[0004] At present, there is no special study on the method of improving the smell of hemp fiber. In the case of strict requirements on the smell, the processing technology of hemp fiber is mainly adjusted to meet the requirements, but the cost will also increase a lot.

Embodiment 1

[0013] Embodiment one: a kind of method of the present invention improves hemp fiber smell under dry state and wet state, adopts following processing steps: its component proportioning is by weight:

[0014] The present invention evenly sprays the tangerine oil of 3 parts of weight on the flax fibers of 100 parts of weight with a sprayer (preparing 2 parts); the spraying distance is 5cm, and then the hemp fiber sprayed with tangerine oil is preserved in an open glass vessel placed in the standard environmental conditions of temperature 21°C and humidity 60% for 12 hours.

[0015] Dry odor test:

[0016] Place one of the above pretreated samples in a ground glass bottle with a ground cap, the volume ratio of the sample to the glass bottle is 1:20, and the sample is hung in the glass bottle through the American AE line without touching the bottom of the bottle , close the lid tightly to prevent air leakage, and then put the glass bottle containing the sample in a ventilated ove...

Abstract

The invention relates to a method for improving the odor of dry or wet fibrilia, in particular for increasing the odor property and the anti-mildew property of a raw material of dry or wet fibrilia for an interior decoration part of a motorcar. The method is characterized by adopting the following process sequences: taking fibrilia and mandarin oil as raw materials; uniformly spraying the mandarinoil on the fibrilia; after the fibrilia on which the mandarin oil is sprayed is placed at the temperature ranging from 21 to 25 DEG C and the humidity ranging from 60 to 70 percent, carrying out an odor test; and putting the fibrilia on which the odor test is carried out in opened glass ware, and assessing the odor of the fibrilia again 15 days later. The method is simple and needs low cost, however, the improved effect is considerably obvious; the method not only can increase the favorable odor of the dry fibrilia, but also can completely improve the annoying odor of the wet fibrilia and also enhance the anti-mildew property of the wet fibrilia; and the improved effect can be maintained for a long time.

Description

technical field [0001] The invention relates to a method for improving the odor of hemp fiber in a dry and wet state, specifically improving the odor characteristic and anti-mildew performance of the hemp fiber in a dry and wet state as a raw material for automotive interior parts. Background technique [0002] With the development of automobile manufacturing technology, the automotive industry has higher and higher requirements for automotive interior parts. In addition to the requirements of aesthetics and environmental protection, it also requires low cost, light weight, high strength, recyclable and biodegradable, and has Better acoustic performance, in order to improve the economy of automobile manufacturing and the comfort of users, so more and more natural fiber reinforced composite materials are used in automobile interior parts. [0003] The automotive interior parts made of hemp fiber can meet the requirements of biodegradability and lightweight, which is conducive...
