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 mandarin oil 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
The present invention relates to a kind of method of improving odor of dry or wet fibrilia, is exactly to improve odor property and the anti-mildew sex change energy of automotive upholstery raw material flax fibre under dried hygrometric state specifically.
Background technology
Development along with auto manufacturing technology, automobile industry is more and more higher to the requirement of automotive upholstery,, the environmental protection attractive in appearance except requiring, also require low cost, light weight, intensity height, recyclable utilization and biodegradable, have an acoustical behavior preferably simultaneously, to improve automobile making economy and user's comfort, so increasing natural fabric reinforced composite is used in the automotive upholstery.
The automotive upholstery that flax fibre is made can satisfy biodegradability can satisfy lightweight requirements again, helps the sustainable development of environment.But find that in actual use the inside gadget of being made by flax fibre is too heavy with the smell of sheet material, test result can not satisfy customer requirement, and the source of its smell mainly is a flax fibre, and especially after flax fibre made moist, smell was just more pungent.
At present also do not specialize in the method for improving the flax fibre smell, under the situation that smell is had strict demand, mainly meet the demands, but its cost also increases much thereupon by the processing technology of adjusting flax fibre.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, thereby provide a kind of method of improving the flax fibre odor properties by tangerine oil, it can not only improve the smelling good of dry state fibrilia smell, and can improve the wet fibrilia odour nuisance fully, can strengthen the method for improving odor of dry or wet fibrilia of anti-mildew sex change under the flax fibre hygrometric state simultaneously again.
According to technical scheme provided by the invention, a kind of method of improving odor of dry or wet fibrilia, adopt following processing step: its component proportioning is counted by weight:
Get 100 parts of flax fibres, 3～7 parts of tangerine oils; Be sprayed at tangerine oil on the flax fibre uniformly; Spraying distance is 5～10cm, is 21～25 ℃ with the flax fibre that is sprayed with tangerine oil in temperature, and humidity is to place the test of the laggard promoting the circulation of qi flavor of 12～24h under 60～70% conditions; The flax fibre of testing is placed in the unlimited glassware, estimates its smell once more after 15 days.
Described flax fibre refers to natural unprocessed linen fibre, tossa or hemp.
Compared with the prior art the present invention has the following advantages:
The inventive method is simple and with low cost, but it improves the effect highly significant, can not only improve the smelling good of dry state fibrilia smell, and can improve the wet fibrilia odour nuisance fully, can strengthen simultaneously the anti-mildew sex change under the flax fibre hygrometric state again, improving effect can keep for a long time.
The specific embodiment
The Henan, the flax fibre place of production of using in the test, the sincere fiber crops industry in effluent south provides, and flax fibre is the natural fiber crops semi-finished product through degreasing combing two procedures.
