Abstract
The present invention relates to a kind of acid fiber by polylactic food-grade binding rope, belongs to food packaging material technical field, and it solves the problems, such as cotton cord security difference in the prior art.This acid fiber by polylactic food-grade binding rope, it is characterised in that described binding rope is made of pure acid fiber by polylactic.This acid fiber by polylactic food-grade binding rope is made of acid fiber by polylactic, because acid fiber by polylactic has natural antibacterial biocidal property, effectively lifts foodsafety.Especially if the food binding rope pooled capital using polyactide fiber filament, its any surface finish, few filoplume, is not easy adhesive tape impurity, further improves the security of food.5~30% are controllable to plus acid fiber by polylactic high-temperature shrinkage rate, bundled strength is more preferable after thermophilic digestion, and food is not easy to scatter, and improves the outward appearance and quality of food.Further, since 100% degradability of acid fiber by polylactic, the feature of environmental protection of food packaging material to environmental concerns, will not be improved.
Description
Technical field
The invention belongs to food packaging material technical field, is related to a kind of food binding rope, particularly a kind of acid fiber by polylactic food
Grade binding rope.
Background technology
In the prior art, the binding rope, the binding rope of meat etc. of the rope of food binding such as Zongzi, food is bundled
Afterwards, generally require together to carry out boiling with food, therefore higher requirement is just proposed for the material of food binding rope.
Most basic requirement is not only food packing rope itself and is free of harmful substance, and also will not after thermophilic digestion
Change and reaction harmful to health are produced with compositions such as the salt in food, sugar.Such as rice-pudding rope, artificial bag Zongzi is using pure natural earliest
Careless class rice-pudding rope, with the industrialized production of food, many manufacturers are convenient for materials procurement and automated production, using change
Fine class plastic ties, such as nylon rope, its cost is cheap, but after high temperature boiling, formaldehyde can be separated out after plastic ties and nylon rope
Each toxoid such as class, bismethane, do harm to huamn body.
Make as country is to the regulatory requirements more and more higher of food production, and to the coloring agent of natural material such as cotton cord
With species and technique, strict limitation there has also been.Using cotton cord as food binding rope, its raw material is plant for most producer
Cotton, chemical substance will not be discharged.But achromophil pure color cotton cord there may be cotton raw material and contain the objectionable impurities such as band heavy metal
Phenomenon, it is difficult to effectively prevent.In addition, cotton cord easily scatters after thermophilic digestion, particularly with Zongzi in thermophilic digestion
If cotton cord scatters, water, which enters in Zongzi, can have a strong impact on mouthfeel and quality, therefore stretching, extension causes rice-pudding when cotton cord can not solve high temperature
The problem of son scatters.In addition, cotton cord is due to there was only chopped fiber, it is necessary to through spinning process, makes to twist ability shape after obvolvent between fiber
Into continuous yarn, there is filoplume on spun fabric surface, plentiful fluffy.Therefore in storage, its surface is crude easily to grow carefully
Bacterium and adhesive tape harmful substance, so as to be unable to reach the hygienic requirements of antibacterial bacteriostatic.
The content of the invention
The purpose of the present invention is the former material based on acid fiber by polylactic natural bacteriostatic in view of the above-mentioned problems existing in the prior art
Expect origin function, it is proposed that a kind of acid fiber by polylactic food-grade binding rope.
The purpose of the present invention can be realized by following technical proposal：A kind of acid fiber by polylactic food-grade binding rope, it is special
Sign is that described binding rope is made of pure acid fiber by polylactic.
The raw materials for production lactic acid of acid fiber by polylactic (PLA) is made from cornstarch, so being also referred to as this fiber
It zein fiber, can be made with garden beet or cereal etc. through glucose fermentation, the polymeric cost of lactic acid is prepared with reduction.Pass through breast
The chemical polymerization of sour Cyclodimerization thing or the direct polymerization of lactic acid can obtain the PLA of HMW.Using PLA as raw material
Obtained product, there is good biocompatibility and Bioabsorbable, and biocidal property, anti-flammability, and degradable
In thermoplastic macromolecule material, PLA has best heat resistance.Therefore the binding rope of food-grade is made of acid fiber by polylactic,
Both meet the security of food, and make use of the antibacterial bacteriostatic row of acid fiber by polylactic again, while acid fiber by polylactic still can naturally drop
Solution, improve environmental-protecting performance.
In above-mentioned acid fiber by polylactic food-grade binding rope, described binding rope is made of polyactide fiber filament.
In above-mentioned acid fiber by polylactic food-grade binding rope, described binding rope is closed using 3-6 polyactide fiber filaments
Stock forms.
In above-mentioned acid fiber by polylactic food-grade binding rope, described polyactide fiber filament specification is 150D -300D.
The binding rope that polyactide fiber filament is formed through plying has surface smooth, is not easy the excellent of the unhygienic impurity of adhesive tape
Point.
Alternatively, in above-mentioned acid fiber by polylactic food-grade binding rope, described binding rope uses PLA
Fiber short fiber yarn is made.
In above-mentioned acid fiber by polylactic food-grade binding rope, described acid fiber by polylactic yams are 8s -40s.
In above-mentioned acid fiber by polylactic food-grade binding rope, described binding rope is closed using 3-10 with acid fiber by polylactic yarn
Stock forms.
Its technique is simple through the binding rope of plying formation for acid fiber by polylactic yarn, and cost is cheap.
Acid fiber by polylactic possesses natural shrinking, and 5%---30% is controllable in thermophilic digestion post-shrinkage ratio.In high temperature
The product of binding is not easy to scatter after boiling, relative can be tightened up on the contrary, increases bundled strength.
Consider from food security angle, acid fiber by polylactic has due to using natural plant starch lactic acid as raw material
Standby natural environmental-protective, while because it possesses stronger bacteria resistance, help to lift the security of food.Additionally, due to poly- breast
Sour fiber filament directly plying forms binding rope, its any surface finish, is not easy the unhygienic impurity of adhesive tape, further lifts the peace of food
Full performance.
Compared with prior art, this acid fiber by polylactic food-grade binding rope is made of acid fiber by polylactic, due to PLA
Fiber has natural antibacterial biocidal property, effectively lifts foodsafety.Especially if using polyactide fiber filament plying
Food binding rope, its any surface finish, few filoplume, adhesive tape impurity is not easy, further improves the security of food.Plus poly-
Acid fiber high-temperature shrinkage rate is controllable to 5~30%, and bundled strength is more preferable after thermophilic digestion, and food is not easy to scatter, lifting
The outward appearance and quality of food.Further, since environmental concerns will not be carried by 100% degradability of acid fiber by polylactic
The feature of environmental protection of food packaging material is risen.
Brief description of the drawings
Fig. 1 is the cross section structure diagram of embodiment 1 provided by the invention；
Fig. 2 is the cross section structure diagram of embodiment 2 provided by the invention.
In figure, 1, polyactide fiber filament；2nd, acid fiber by polylactic yarn.
