In once the cany bamboo furniture of disfavor and its products, like the cany sofa bed, cane, cane, bamboo, bamboo mat screen and cany box, in recent years, urban family sadly again return more and more get the welcome of people and favour.
According to expert introduction, nowadays the cany bamboo furniture of classic euramerican style, expression of western-style furniture, accord with national characteristics of east Asia furniture of emotional appeal. These cany furniture if deserve all the geometry of the table, such as telephone table is put in capacious and bright sitting room, can show master knowledge, taste, temperament and accomplishment.
Fine workmanship and modelling novel cany table, cane, cane, cane, bamboo, sofa, bookshelf of screen color mostly natural guileless and simple sense is strong, in primitive syncopation is decorous, make the bedroom is full of carefree and happy, halcyon natural appeal. At the same time, using a cane to make furniture still can reduce the chemical fibber plank, plastic, paint, coating, such as glue of chemical pollution of the environment. On the market, the vitreous mesa circular cany chair of table and thick cane four combinations furniture is very conspicuous. In addition, small size, concise bamboo kitchen and lively double drawer desk, lover desk, distinct, strewn at random have the ark of almirah, multi-purpose cane, all make a person fondle admiringly.
Cany bamboo furniture USES pure natural plant material preparation, put inside the bedroom in summer the pale yellow or white, ivory lubricious annatto the cany bamboo furniture is most appropriate. In winter, if give them with thick fabric or soft cloth, more can create warm home environment.
"Pack" home health, bamboo floor to human body health benefits of 10
Bamboo is renewable natural environmental protection material. First of all, we know the bamboo forest, can cut once sustainable utilization, because each year through their reproductive bamboo constantly forming the expansion of bamboo forest, is a gift to replace human wood environmental protection material. DaZhuang use 4-6 years of moso bamboo flooring, and DaZhuang timber processing selected in Europe import standards, in a cubic meters of adhesive materials with no more than 30 kilograms of glue, far less than 400 kilogrammes of aggrandizement floor. Because exports to Europe and the united DaZhuang floor area, ten years ago, the formaldehyde to E1 standard (1.5 mg/L) and even E0 level (0.5 mg/L). Bamboo floor to have several benefits:
1, prevention of rheumatism bamboo has automatic adjustment and keep temperature, heat, cold winter not, long live, can reduce rheumatoid arthritis, rheumatism, and heart disease.
2, the health care eyesight bamboo flooring texture with absorb ultraviolet light, colour and lustre is elegant, the function of downy and sweet, visual beneficial, can reduce myopic happening.
3, reducing noise and bamboo itself has sound-absorbing, sound insulation, the sound pressure reducing, shorten the time of residual sound.
4, avoid to fall bamboo floor itself with modest hardness, the doctrine of coarse, can avoid to fall.
5 and avoid allergic asthma syndrome in through the high-temperature cooking, bamboo, remove after bleaching, carbonized fibre inside all nutrients, completely destroy insects and the conditions of existence, bacteria, can reduce the moth and mildew asthma, allergies.
6 and eliminate fatigue and bamboo is elastic and can ease of gravity, and step into eliminate fatigue.
7 and natural characteristics of bamboo and people are natural beings, and the texture of bamboo in the irregular change, and the rules of natural color, special bamboo texture, as the song dynasty poet su dongpo "would rather eat no meat, cannot ju mozhu" is elegant and natural materials in the name of the precious symbols.
8 and natural aroma and bamboo texture sends out beautiful, still can emit fresh fragrance gas, be beneficial to health of body and mind.
9 and maintenance is simple, easy to use wet cloth to wipe or twist dry mop wipe can easily, installation, no one accurate, paint, province, no pollution, dust, indoor environment is good maintenance.
10 and natural health anti-aging 1945 Hiroshima and Nagasaki suffered from Japan, dozens of atomic explosion hazard of square kilometers within the scope of the life, the area of misery suffered, however the scorched earth have shoots speared out fast growth, forming new bamboo. Therefore deemed with super bamboo species of vitality. According to the Chinese materia medica of about bamboo sterilization, lowering 20 different kinds of medicinal herbs, function and nearly 1000 kinds of folk more bamboo prescription... Through modern technology, the extraction of bamboo essence is widely applied in medical care and hairdressing cosmetic, and use natural bamboo processing of bamboo floor in the health care function is self-evident.
Bamboo fiber identification methods were reviewed
Bamboo is our own r&d and industrialization of new-type cellulose, according to the different processing methods, have ZhuYuan fiber and bamboo pulp fibers. ZhuYuan fiber by physical method for processing, does not add any chemical reagent, for 100% natural fibers [1]. Bamboo pulp fibers with chemical method, via hydrolysis (processing) and bleaching exists for pulp, made by the characteristic for spinning made bamboo pulp fiber [2-3], is similar to a chemical viscose spinning process.
Bamboo fiber as a rich, renewable sources, biodegradable, development and utilization of resource fibre broad prospects, more and more people's attention. People on the basic of bamboo fiber and chemical composition, physical and chemical properties of organizational form the basis of a study [4-8], and through the different methods of bamboo fiber and its products are developed [9-11]. ZhuYuan fiber for pure-fiber, excellent performance and special products of style, and have excellent antibacterial properties, dry comfort good summer. Bamboo pulp fibers in the process of spinning performance by large and powerful low, crystallinity, low, a sparse, arrangement, belong to high rates of moisture and viscose fiber similar regenerated celluloee fiber [12]. Bamboo pulp fiber although improved ZhuYuan fiber strength, elongation rate of unevenness of fiber, toughness and wear resistance, etc, but has increased some of its natural characteristics of fiber damage, deodorization, antibacterial, anti-ultraviolet function was decreased, wet strength also drop more [13].
Because ZhuYuan fiber and bast fibres fiber, bamboo pulp fiber with viscose fiber morphology and properties similar [14-15], to identify work brings great difficulty. Domestic bamboo fiber identification standard, only T1901 SN / - 2007 "seven textile fibers of the series identification method mentioned bamboo pulp fiber and six fiber qualitative identification method. But not how to identify its structure, properties of similar viscose fiber, ZhuYuan fiber, fiber and its blending products.
1 bamboo pulp and ZhuYuan fiber identification methods
ZhuYuan fiber and bamboo pulp fiber with bamboo as though based raw materials, but the process is completely different, difference is very big. ZhouJianPing [4] through the ZhuYuan fiber and bamboo pulp fiber, the contrast that bamboo fiber, performance is superior to stretch degree coefficient of variation of small and large, fiber tenacity, elongation resistance, good spinnability. The two kinds of bamboo fiber and chemical thermal properties research results in table 1.
[12] over equal, sun Juan in such [16], the study found ZhuYuan structurally is typical of cellulose fiber type high crystallinity, macromolecular crystallization, regular arrangement, A section of the form, have ZhongQiang kidneys, wall is cracked. And bamboo pulp fiber is typical of cellulose type II crystallization, crystallinity and ordinary, section, viscose fiber, irregular polygons in a zigzag, longitudinal surface has many grooves, make bamboo pulp fiber has good hygroscopic, wet, and enhance the force between the fiber, yarn processing. From the performance, ZhuYuan fiber crystallinity, thermal stability and antibacterial properties of bamboo fiber are good at, ZhuYuan fiber high-strength low stretch fiber of bamboo fiber and low intensity tall the tender fiber, The resurgence of bamboo fiber and glue, and ZhuYuan consistent 13% of fiber regain.the for 6% to 7%.
ZhouQiuBao [17] reports, etc ZhuYuan fiber and bamboo pulp fiber can dissolve in different concentrations of sulfuric acid, hydrochloric acid, nitric acid and dissolution rate of bamboo fiber is better than the alkali ZhuYuan fiber, can dissolve calcium chloride with formic acid mixture in sodium hypochlorite solution, bronze and ammonia solution, and both are insoluble in other tried 24 organic solvents. ZhuYuan fiber is obviously higher than the ultraviolet ability, and bamboo pulp fibers both the ultraviolet colouring performance than it has improved greatly. YangQingBin [18] as a treatment for research ZhuYuan fiber and mechanical properties of bamboo fiber. Results show that ZhuYuan fiber with high initial modulus, wet when compared to the mechanical properties of the fibers in the dry condition. Bamboo pulp fibers, the elongation except the tensile fracture mechanics performance indicators are far below ZhuYuan fiber.
The study showed that ZhuYuan fiber and bamboo pulp fibers in the structure and properties of a difference, such as shape, crystal structure, crystallinity and mechanical properties, thermal stability, chromatic performance etc. But due to the complex operation or when viscose and bast fibres etc structure and performance of the fibers are similar, fast and accurate identification of these two kinds of fibers, the difficulty of the corresponding standard no.
2 the bamboo pulp fiber identification methods were reviewed
ChenBaoXi [19] as determined by test, in acid solution concentration (0.5) %, 60 ± solubility temperature (25 ± 2) degrees, dissolve time (20 ± 2) min etc, conditions that can be accurately determined conveniently bamboo fiber/cotton blended product fibre content. LiuLanFang etc. [20], 37% in temperature 25 degrees Celsius, hydrochloric acid for 10min conditions and acid solution of zinc in temperature - 50 ° c, time 90min condition, can dissolve method for determination of bamboo fiber and cotton textile fiber ratio of two components.
MaShunBin etc. [21] research shows that bamboo pulp fibers and viscose fiber, just as the combustion characteristics in different colors on the residue, bamboo pulp fiber color is dark, the color is hoar viscose fiber residue. There are two longitudinal and transverse section of edge slots are irregular jagged, just bamboo pulp fibers without skin-core structure and viscose fiber has skin-core structure. Both the same infrared spectra, dissolve properties similar to absorb map used to identify. SuiShuYing etc. [3] using X-ray diffraction method was bamboo pulp fibers for 31.6%, crystallinity of viscose fiber for 30% of the crystallinity crystallinity, basically the same. Yan he jing etc. [22] by scanning electron microscope (sem) analysis found that bamboo pulp fiber cross section was full of holes, it has fine wet absorption capability. Viscose fiber morphological structure and bamboo pulp fiber similar, but no holes in cross section. In fiber thermogravimetic analysis shows that the heat decomposition of bamboo fiber than viscose fiber properties. Zhang tao [23] through such research viscose fiber - OH a bamboo pulp fiber vivacity, bamboo pulp fiber in 3450cm - 1-1 3250cm - the - OH absorption than viscose fiber, it is clearly identify the two kinds of fibers is one of the effective means. 24] [LiZhiGong etc by microscopy, can quickly longitudinal morphological characteristics between Lyocell, cotton and chitin fibers, With 37% hydrochloric acid, under normal temperature observation, Modal quickly dissolution dissolution, ordinary viscose fiber dissolving but slightly slower than Modal degrees, bamboo pulp fiber only partly dissolved. Using density gradient density, bamboo fibre tube were significantly lower density, Lyocell, ordinary viscose Modal and cotton. Yang yuan [25] through the study by coloring and burning or through the comparison between the tensile properties of bamboo pulp fibers and viscose fiber. YangJian equal [26] use 55-90% of the concentration of sulfuric acid solution to identify bamboo pulp fibers and Modal fibre, and through the solution viscosity of quantitative analysis and identification of viscose bamboo fiber blend of bamboo fiber mixing ratio.
Bamboo pulp fiber and cotton qualitative and quantitative analysis method of made progress, but the bamboo pulp fiber and viscose fiber ongoing research method, the solubility of density and microscope observation research studies, complex operation or distinguish the effect is not obvious, in applications are great limitations, without being popularized.
3 ZhuYuan fiber identification method
ZhuYuan fiber and author of the structure and properties of the fiber with similar, its minro-form author fiber has many similarities between, easy. ShiGong etc. [14] study, the conventional method of density of fibrous projection method, the method, the method is not suitable for dissolved method ZhuYuan qualitative identification and flax fibers. According to ZhuYuan fiber flax and molecular structures of CH and - CH2, degree of polymerization (CH3 - the number of infrared spectra, found differences in 2900cm - 1 and 2850cm - 1 in relatively obvious difference, using the spectra can ZhuYuan fiber flax and reproducible. TianHuiMin etc. [27] that ZhuYuan fiber surface groove and grain, secondary layer are three concentric layers structure of secondary fiber, outer with fiber axis almost parallel arrangement, internal have plenty of empty. Through calculation of the ir spectra of ZhuYuan ki index shows that after ramie fibre crystallinity, cotton and flax fibers. ZhuYuan fiber has stronger molecules of hydrogen bonds, cellulose crystal to the beta I I beta content, but higher than cotton fiber flax fibers. HeJianXin etc were measured] [28 > and ramie, flax chemical composition of materials and single fiber dimensions, see table 2. Through the X-ray diffraction ZhuYuan shows the crystallinity and grains fiber orientation and ramie, flax, cotton, and the above ZhuYuan fiber grain size than other three kinds of fiber.
High road for several fibers [29] made preliminary identification and draw the following conclusion: the fiber length in about a 3mm section and large ZhongQiang ovoid, hemp section for jute fibres can determine, Single fiber length mostly in 80mm ~ 120mm thicker, waist, section, ZhongQiang squash, walls have crack, longitudinal have linen section for ramie, A small section of ZhongQiang polygons and longitudinal section of Massachusetts, there is the flax fibers, Single fiber thickness difference in mm, length, circular cross-section shape, ZhongQiang squashed waist, longitudinal surface roughness, horizontal section of vertical for hemp fibre, Extremely short fibers, section, 3mm in smaller, and ZhongQiang approximate circular vertical rough, like bark, without the ZhuYuan fiber for slubby. But it also pointed out the separation effect of single fiber to the accuracy of measurement results of fiber plays an important role, but also directly affect the fiber to form of observation. CaiYuLan etc. [results] the 13CNMR 30 ZhuYuan calculation and ramie, flax, cotton samples, and the content of crystal fiber and flax fibers, compared with the ZhuYuan grain size, and ramie close, see table 3. X-ray diffraction and nuclear magnetic resonance (NMR) two results showed that ZhuYuan fiber and crystallinity ramie cotton, flax, and more.
ZhuYuan fiber and author of fiber identification method, the ongoing microscope observation, nuclear magnetic resonance (NMR) method, the method of ftir research, due to the difficulty of sample preparation and accuracy, not actual application, so there is no corresponding identification methods standards.
To sum up, and bamboo fiber identification methods for a while, but due to the complicated operations or because the effect is not apparent, distinguish in application are great limitations, without being popularized. Therefore, the bamboo fiber quick and easy, effective identification method is the research direction in the future.
