Abstract
The invention discloses a straw fiber and jute fiber blended non-woven fabric for a piece of warming anti-bacterial, environment-friendly and seamless wall paper. The non-woven fabric is made from the following raw material according to weight by parts: straw taking up of 200 to 205 parts, original hemp of 100 to 104 parts, proper amount of NaOH, proper amount of water, polyving akohol of 0.8 to 0.85 part, lignin of 0.5 to 0.6 part, methylacrylic acid trifluro-ethyl ester of 0.2 to 0.3 parts, methylacrylic acid Dodecafluoroheptyl of 0.2 to 0.3 part, ethyl acetate of 5 to 6 parts, tea tree essential oil of 0.3 to 0.4 part, activated carbon fibers of 2.5 to 3 parts, nanometer polytetrafluoroethylene of 0.3 to 0.4 part, and peroxidation cumin of 0.05 to 0.1 part. With the use of the tea tree essential oil and the activated carbon fibers, the non-woven fabric has performance of preventing bacteria and absorbing harmful gas; and tenacity, tear-resistance and low temperature-resistance of the non-woven fabric are enhanced due to the use of the polyurethane acrylic resin and the lignin.
Description
Technical field
The present invention relates to nonwoven fabric manufacturing technology field, particularly relate to the seamless wallpaper rice-straw fibre of a kind of antibacterial environment protection and flax fibre hybrid nonwoven cloth and preparation method thereof.
Background technology
There is abundant stalk resource in China, occupies first of the world.Wherein rice straw accounts for 27.5%, and maize straw accounts for 36.7%, and wheat stalk accounts for 15.2%, and can be used as the stalk total amount that the energy is used is 3.761 hundred million t.At present, a large amount of discarded rice straw still faces and burns this unique process approach.Exploitation rice straw novelty teabag, solves rice straw process new problem, both can reduce rice straw as the environmental pollution brought after castoff burning and management cost, and also can turn waste into wealth, and make full use of the value of rice straw resource itself, economize on resources.
By chemical constitution study, in rice straw, make it can be used as providing the resource of native cellulose fibre containing the cellulose reaching 31.51%.There is a large amount of rice straw resources in China, if can be used by weaving, can create good economic worth and environmental value.And utilize the prerequisite of rice straw fiber to be to remove other impurity of rice straw.Found through experiments, extracting at rice straw in the technique of fiber to use certain density NaOH to carry out alkali lye kiering to rice straw, to remove its major impurity such as the hemicellulose contained and lignin, thus obtain comparatively ideal fiber, for following process process.In order to efficiency utilization reclaims rice straw, consider to utilize nonwovens process to be made as nonwoven fabric.But because the mechanical properties such as rice straw brute force itself are poor, can must produce a desired effect with other known traditional fibre are blended.
The function admirable of flax fibre, biocompatibility is good.Along with the continuous progress of technology of nonwoven, application flax fibre is that raw material is produced high performance non-weaving cloth and become heat subject.This test selects flax fibre and rice straw fiber to carry out blended, and its feature is as follows: (1) is more excellent based on flax fibre brute force, and fiber stiffness is comparatively large, can make up the shortcoming of rice straw fiber strength deficiency.(2) because flax fibre contains a large amount of polar hydrophilic group, giant fibril longitudinal splitting and present many cracks and hole, and be communicated with lumen by capillary channel, this kind of structure makes flax fibre have remarkable moisture permeability (official regain is about 15%), and this growth for agricultural plant and preservation have good effect.Meanwhile, good hygroscopicity makes flax fibre have stronger antistatic behaviour.(3) natural chemical substance contained by flax fibre has the function of anti-bacteria.Under normal conditions, in the hole in flax fibre, be full of air, be unfavorable for the breeding of anaerobic bacteria, there is fungi-proofing, mildew-resistant, deodorization, corrosion-resistant function, antibacterial, bacteriostasis is more excellent.(4) as native cellulose fibre, the more cheap easy acquisition of flax fibre, and be all bast fibers with rice straw, composition is similar, when extracting fiber can kiering simultaneously to save operation, reduce costs.
Mixed with flax fibre by rice-straw fibre, with polyvinyl alcohol as adhesive, the nonwoven fabric of making has good hygroscopicity, higher fracture strength.If using the bottom of this nonwoven fabric as seamless wallpaper; can not only cost-saving, protection of the environment, raising straw additional application be worth; and useful to health, but the performances such as the hygroscopicity of this nonwoven fabric, intensity, durability can't meet the demands, and need to improve.
Summary of the invention
The object of the invention is exactly the defect in order to make up prior art, provides the seamless wallpaper rice-straw fibre of a kind of antibacterial environment protection and flax fibre hybrid nonwoven cloth and preparation method thereof.
The present invention is achieved by the following technical solutions:
