Description
Technical field
The present invention relates to a kind of yarn, especially a kind of antibacterial blended yarn and manufacturing technique thereof, belong to new type yarn technical field.
Background technology
According to the knowledge of the applicant, black bamboo Carbon fibe has good bacteriostasis property and superpower absorption property, is widely used in antibiotic fabric, especially underclothes; Bamboo charcoal powder in black bamboo Carbon fibe contains Determination of multiple metal elements and the carbides thereof such as potassium, magnesium, manganese, has very strong far infrared transmission and anti-ultraviolet function.The multi-functional characteristics such as distinctive comfortable, healthy, the environmental protection of black bamboo Carbon fibe, health care have caused the concern of textile limit.China is bamboo resource big country, and black bamboo Carbon fibe is drawn materials conveniently, and the exploitation of its product effectively can utilize the bamboo resource of China's abundant, the product that exploitation is unique.
Modal fibre as artificial native cellulose fibre, its good hand touch, comfortableness is strong, and skin-friendly is good, have high-hygroscopicity, and water imbibition and gas permeability is all better than cotton, and spinnability is comparatively strong, is applicable to carrying out blending with other fiber; Modal fabric is bright and full, is desirable health product and fabric next to the skin.
In apocynum fibre, content of cellulose is up to 81.4%, and fibre strength is high, and soft, has stronger wettability power, and corrosion resistance is strong, is described as " king of wild fiber ".Apocynum fibre has stronger antibiotic property, now there are some researches show, apocynum fibre to the bacteriostasis rate of staphylococcus aureus, pseudomonas aeruginosa, Escherichia coli and Candida albicans can up to 50% and more than, bluish dogbane fabric through wash aseptic rate after more than 30 times still higher than general fabrics 10-20 doubly.In addition, bluish dogbane and textile BLENDED FABRIC drapability, antistatic behaviour are better, and moisture absorption is loose wet fast, has the outward appearance as silk.
Needing badly at present can be the technological means of yarn by above-mentioned fiber blend.
Summary of the invention
Technical problem to be solved by this invention is: overcome prior art Problems existing, provides a kind of antibacterial blended yarn, has excellent anti-microbial property and strong adsorptivity, can intercept fine particle; The manufacturing technique of this yarn is provided simultaneously.
The technical scheme that the present invention solves its technical problem is as follows:
A kind of antibacterial blended yarn, is characterized in that, formed by the blending by weight percentage of following composition:
This yarn, while having good yarn quality, has the strong adsorptivity of black bamboo Carbon fibe, the anti-microbial property that apocynum fibre is outstanding, skin-friendly, comfortableness and soft feel that Modal fibre is outstanding; Be particularly useful for making mouth mask, not only anti-microbial property is lasting, can also intercept fine particle with strong adsorptivity.
The present invention also provides:
A manufacturing technique for antibacterial blended yarn, is characterized in that, comprises the following steps:
The first step, black bamboo Carbon fibe, Modal fibre, the first long-staple cotton are mixed and makes the first lap; First apocynum fibre is mixed with the second long-staple cotton and makes the second lap;
Second step, the second apocynum fibre mixed with the first lap and makes first carded sliver; Second lap is made second carded sliver;
The ratio of described black bamboo Carbon fibe weight, Modal fibre weight, the first long-staple cotton and the second long-staple cotton weight sum, the first apocynum fibre and the second apocynum fibre weight sum is 40-50%:10-15%:15-20%:20-25%;
3rd step, first, second carded sliver is made ripe article through mixing in doubling step; Again ripe bar is obtained antibacterial blended yarn through Roving Frames, spinning process successively.
Applicant finds through going deep into practical studies, adopt this technique black bamboo Carbon fibe, Modal fibre, long-staple cotton and apocynum fibre can be made the good antibacterial blended yarn of yarn quality, especially second step wherein and the 3rd step achieve apocynum fibre respectively and mix with the first time of its excess-three kind fiber and mix for the second time, substantially increase the utilization ratio of apocynum fibre.
