Abstract
The invention relates to antibacterial protein fibers. In the antibacterial protein fibers, the size is 1.0 to 7.0dtex, the cross section has a round and leather-cored structure, polyolefin which contains soy protein is used as a skin layer, polyolefin which contains silver-carrying attapulgite is used as a core layer, the mass ratio of the skin layer to the core layer is 25:75-80:20, the soy protein in the skin layer accounts for 3 to 10 percent of the mass of the skin layer, the silver-carrying attapulgite in the core layer accounts for 1 to 10 percent of the mass of the core layer, and the mass ratio of the attapulgite to the silver in the silver-carrying attapulgite is 1,000:1-100:1. In the invention, the fibers are manufactured by a skin-core composite melting spinning process, the addition of the soybean protein in the skin layer makes the fibers skin-friendly, antistatic and fat-absorbing, the silver-carrying attapulgite in the core layer improves the antibacterial property of the fibers and removes odor, the harm of silver to human bodies in the processing and use processes of the fibers is avoided, the production cost is low, and the added value is high.
Description
Technical field
The present invention relates to the functional fibre technical field, be specially a kind of antibacterial protein fiber.
Background technology
Along with national economy continues high development, the raising of per capita income, people are to environmental sanitation and the healthy pay attention to day by day of oneself, the hygienic material demand constantly increases, antibiotic fabric wherein, especially the Application Areas of the antibiotic fabric of non-weaving cloth also constantly enlarges thereupon, as sanltary towel, filtration fabrics, socks, pants, the textile product of public place particularly, as medical and hygiene article, the bedding of ward, operating room and dressing, the tablecloth on the train, mattress list, lid list, the bedding in hotel, the hotel etc. all should adopt antibiotic fabric.This kind fabric when being used for sanltary towel, absorbent cotton, hospital gauze etc., also should have functions such as adsorptivity such as skin-friendly, hydrophily, permeability, blood and fat except that should having avirulence, security, antibiotic durability.Patent 200820217220.X has reported a kind of antimicrobial pearl yarn of core-sheath composite structure, and sandwich layer and cortex are respectively and contain the polyester composition that silver is laminar nano antimicrobial powder and nano-pearl powder.
Soybean protein is renewable plant resources, contains multiple reaction active groups in its molecular structure, is easy to chemistry and physical modification.Soybean protein is used for chemical fibre, can gives fibrous material some biological function characteristic,, not only can be used as textile material, also can be used for special dimensions such as biology, medical science as biocompatibility, permeability, blood and fatty adsorptivity etc.Existing application number is many reports that utilize soybean protein to carry out fibre modification such as 99116636.1,03115288.0,02138823.7,200410013429.0 and 02109966.9.
Attapulgite (or claim attapulgite) is the natural nano structure mineral material with nanochannel structure, and it has very strong adsorptivity and sterilization, deodorizing, detoxification, killing ability.Under suitable condition, silver nitrate and attapulgite and organic reducing agent chemical reaction, silver loads on attapulgite clay nano rhabdolith surface with exchangeable ion and two kinds of forms of nano-Ag particles, the only several nanometers of particle silver diameter that form, this silver-colored particle has very big activity, can constantly slowly release antibiotic essential silver ion, nano-Ag particles combines with attapulgite firmly, silver-carrying concave-convex stick soil has good anti-microbial property, and application number 03131757.X has reported attapulgite-Yin nano composite antibiotic material and preparation method thereof.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, a kind of antibacterial protein composite fibre is provided.The objective of the invention is to be achieved through the following technical solutions:
A kind of antibacterial protein fiber, cross section are circular, skin-core structure, are cortex with the polyolefin that contains soybean protein, are sandwich layer with the polyolefin that contains silver-carrying concave-convex stick soil.
Described polyolefin be fibrous polypropylene, poly one or both.
To account for the cortex quality be 3-10% to the quality of soybean protein in the described cortex.
To account for the sandwich layer quality be 1-10% to the quality of silver-carrying concave-convex stick soil in the described sandwich layer.
The fiber number of described polyolefin composite fibre is 1.0-7.0dtex.
The mass ratio of described cortex and sandwich layer is 25: 75-80: 20.
Described soybean protein is soybean protein isolate (SPI), and protein content is greater than 90%.
In the silver-carrying concave-convex stick soil attapulgite with silver mass ratio be 1000: 1-100: 1.
The present invention adopts the spinning technique of known core-sheath compound fibre to make, because cortex added soybean protein, makes fiber have skin-friendly, antistatic behaviour and to the adsorptivity function of blood and fat; And the silver-carrying concave-convex stick soil in the sandwich layer has increased the antibiotic property of fiber, the effect of elimination peculiar smell; Avoided in fiber process and silver-colored harm in using to human body; Production cost is low, the added value height; Product can be used for clothes, medical and hygiene article, bedding etc.
