Description
Technical field
The present invention relates to modified cellulose technical field, relate in particular to a kind of antibacterial and deodouring cellulose fibre and preparation method thereof.
Background technology
Along with social progress and the raising of people's living standard, the idea of people's dressing is also constantly being upgraded, and the Comfortable attractive of the functional and product to textiles is had higher requirement.And the production of the natural fabrics such as cotton, fiber crops, silk, hair due to be subject to natural climate and grain and cotton strive ground contradiction impact, increase of production is very slow, far away can not practical requirement.
Occurring in nature cellulose not only storage level is large, and is a kind of inexhaustible, nexhaustible renewable resource.This raw material also only has a little fiber that is made at present.Along with deepening continuously that the mankind are familiar with nature, cellulosic utilization also will expand gradually.In contrast to this, synthetic fiber are mainly to be produced by the raw material (oil, coal, natural gas etc.) that the different geologic(al) periods form, although the storage capacity of these raw materials is very large, it is consuming gradually, and is difficult to recover.Have scholarly forecast, tellurian petroleum resources will be used up to mid-term 21st century.And cellulosic resource is unlimited, it is constantly natural synthetic with huge speed.
21 century is the further protection of the environment of requirement and the epoch of making rational use of resources.Cellulose fibre is owing to being changed into steam and carbon dioxide by biological decomposition or safe combustion, and the welding problem being caused by discarded object is few.As can be seen here, no matter from the degree of enriching of resource, from the processing of discarded object, and many-sidedly consider from the comfortableness of dress and elegant in appearance grade, it is very necessary developing cellulose fibre.
At present China's viscose kind majority is general fibre, and functional fiber, fibre in differentiation are little.Though the domestic production technology of having grasped coloured fiber, fire resistance fibre, superfine denier fiber, the producer that forms mass production capabilities is few.According to insider analyze, China's fibre in differentiation quality with quantitatively with still have gap abroad.At present domestic because plurality of raw materials can not meet the needs of export market, garment exportation fabric 70% is by import.One of the main reasons is new technology, new product development ability, high-caliber differentialand functional fiber limited amount.According to statistics, Europe, the United States, Deng developed country per capita viscose consumption figure are 1.3 kilograms, are 6 ~ 7 times of developing country.This shows that fibre in differentiation not only has domestic market widely, and has wide international market.Therefore be necessary Devoting Major Efforts To Developing high-performance, differential kind, meet domestic and international market demand, improving product competitiveness.
