Embodiment 1

[0024] Such as figure 1 As shown, in the polylactic acid fiber food-grade binding rope, the binding rope is made of three pure polylactic acid fiber filaments 1, and the specifications of the polylactic acid fiber filaments are 150D-300D. The binding rope formed by plying polylactic acid fiber filaments has the advantages of smooth surface and not easy to stick unhygienic impurities. Coupled with the natural antibacterial and antibacterial properties of polylactic acid fiber, it has a good promotion effect on improving food hygiene and safety.

[0025] The raw material of polylactic acid fiber (PLA) is lactic acid obtained from cornstarch, so this fiber is also called corn fiber, which can be made from sugar beets or grains through glucose fermentation to reduce the cost of preparing lactic acid polymers. Polylactic acid with high molecular weight can be obtained by chemical polymerization of cyclic dimer of lactic acid or direct polymerization of lactic acid. Products made ...

Embodiment 2

[0029] Such as figure 2 As shown in the present polylactic acid fiber food-grade binding rope, the binding rope is made of 4 polylactic acid fiber staple fiber yarns 2 ply, and the specifications of the polylactic acid fiber yarns are 8s-40s. The binding rope formed by plying polylactic acid fiber yarns has simple process and low cost. The pre-shrinking process is required to complete the joint stock, and the binding rope is pre-shrunk when it encounters water to prevent the shrinkage rate of the finished product from increasing due to water contact during use. After the pre-shrinking treatment is completed, the shrinkage rate of the binding rope after high-temperature cooking can be controlled. Between 5% and 30%, the bundled products are not easy to scatter after high-temperature cooking, but will be relatively tightened to increase the bundle strength.

[0030] From the perspective of food safety, polylactic acid fiber is naturally environmentally friendly because it uses...

Abstract

The invention relates to a polylactic acid fiber food grade binding rope, and belongs to the technical field of food packaging materials. The problem that an existing cotton rope is poor in safety issolved. The polylactic acid fiber food grade binding rope is characterized in that the binding rope is made of pure polylactic acid fiber. The polylactic acid fiber food grade binding rope is made ofpolylactic acid fiber. Due to the fact that the polylactic acid fiber has the natural antiseptic antibacterial activity, and the food safety is effectively improved; particularly, if the food bindingrope obtained by plying polylactic acid fiber filaments is adopted, the surface is smooth and clean, has little hair and is not likely to be provided with sundries in a sticky mode, and the food safety is further improved. By adding polylactic acid fiber, the high-temperature retraction rate can be controlled to be within 5-30%, the binding strength is better after high-temperature digestion, foodis not likely to be scattered, and the food appearance and quality are improved. In addition, due to the 100% degradation property of polylactic acid fiber, no damage is caused to the environment, and the food packaging material environmental friendliness is improved.

Description

technical field [0001] The invention belongs to the technical field of food packaging materials, and relates to a food binding rope, in particular to a polylactic acid fiber food-grade binding rope. Background technique [0002] In the prior art, the ropes used for food bundling, such as the bundling ropes for zongzi, the bundling ropes for meat, etc., often need to be steamed together with the food after bundling the food, so higher requirements are put forward for the materials of the food bundling ropes. . [0003] The most basic requirement is not only that the food wrapping rope itself does not contain harmful substances, but also that it will not produce harmful changes and reactions with salt, sugar and other ingredients in the food after high-temperature cooking. For example, zongzi, the earliest artificial zongzi was made of pure natural grass zongzi. With the industrialization of food production, many manufacturers used chemical fiber plastic ropes, such as nylon ...
