Abstract
The invention discloses a nanometer antibacterial bamboo-carbon viscose fiber, which has lasting antibacterial effect, thus prevents microorganism and mould from forming and prevents peculiar smell from generating, comprising 0.005per mill to 0.025per mill nanometer silver (in weight ratio), 5% to 15% bamboo carbon (in weight ratio) and balance of artificial fiber. The manufacturing method comprises the steps that: nanometer silver, sodium sulfite and bamboo carbon are mixed and blended with alkali solution; the obtained solution comprises 0.05 to 0.2 g/L nanometer silver, 50 to 100 g/L bamboo carbon, 10 to 30 g/L alkali and 8 to 10 g/L retardant of sodium sulfite; the mixture is stirred evenly and filtered; then the filtered mixture and the spinning dope with volume ratio of 3 to 10 : 50 are completely mixed through a pre-spinning pipeline spinning injection device, and are spun and formed through the spinning technology; finally the product is obtained through the post treatment technologies of scouring, drying and cutting off. The bamboo-carbon viscose fiber produced through the method is mainly used as the material of various underclothes and hygienic articles.
Description
Technical field
The present invention relates to nano antimicrobial bamboo carbon viscose fiber and manufacture method thereof.
Background technology
The development trend of viscose is differential and functionalization.Exploitation viscose new varieties are improved its performance, and are made it that some specific function be arranged, and are importances of current fiber industry technological progress.Differential viscose is of many uses, and the added value of product height meets the needs that people's living standard improves constantly.Though present viscose kind is more, does not all have sustained antibacterial function, can not stop the appearance of microorganism, mould formation and peculiar smell; And present viscose traditional processing technology, can not guarantee the even distribution of filler, make filler can not give full play to its effect.
Summary of the invention
A technical problem to be solved by this invention is: provide a kind of and have the durable antibiotic effect, can stop microorganism, mould forms and the nano antimicrobial bamboo carbon viscose fiber of the appearance of peculiar smell.
For solving the problems of the technologies described above, the technical solution used in the present invention is: nano antimicrobial bamboo carbon viscose fiber, contain the bamboo carbon of the Nano Silver and 5～15% (weight ratio) of 0.005～0.025 ‰ (weight ratio), and surplus is an artificial fibre.
The particle diameter of above-mentioned Nano Silver is less than 50 nanometers, and the particle diameter of described bamboo carbon is less than 1 micron.
Another technical problem to be solved by this invention is: a kind of manufacture method that makes the uniform more nano antimicrobial bamboo carbon viscose fiber of distribution of Nano Silver and bamboo carbon is provided.
For solving the problems of the technologies described above, the technical solution used in the present invention is: the manufacture method of nano antimicrobial bamboo carbon viscose fiber, the steps include: Nano Silver, sodium sulfite and bamboo carbon to be carried out mixing preparation with alkali lye, content of nanometer silver is 0.05～0.2 grams per liter in the solution that makes, and the bamboo carbon content is 50～100 grams per liters; Alkalinity is 10～30 grams per liters; Sodium sulfite content is 8～12 grams per liters; Should mix the liquid back that stirs filters, mixed liquor after will filtering again and spinning solution are by 3～10: 50 (volume ratios) are fully mixed by spinning the preceding pipeline injection device, through the spinning technique spinning moulding, pass through aftertreatment technology more then: concise, oven dry, cut off, make finished product.
Concise employing is that endless tow is concise in the above-mentioned aftertreatment technology, and what cut off employing is that dry method is cut off.
The invention has the beneficial effects as follows: nano antimicrobial bamboo carbon viscose fiber of the present invention is owing to contain a certain proportion of Nano Silver, thereby had lasting antibacterial effect, can stop microorganism, mould to form and the appearance of peculiar smell; Owing to mixed bamboo carbon, make the simple and elegant delicate fragrance of described bamboo carbon viscose fiber, and have features such as super large specific area, superelevation absorption, can block electromagenetic wave radiation, emitting far-infrared, regulate humiture and beauty and skin care.Manufacture method of the present invention can farthest be brought into play its effect so that Nano Silver and the distribution of bamboo carbon in bamboo carbon viscose fiber are more even.
