Embodiment 1

[0039] A kind of thin jute fiber non-woven fabric for packing, its component is calculated by weight percentage: 65% of jute fiber, 35% of PLA fiber. The thin jute fiber non-woven fabric for packaging is made through the following steps, and the process flow chart is shown in figure 1 :

[0040](1) Carry out health-preserving treatment of jute fiber;

[0041] (2) Carding the jute fibers after the health-preserving treatment, and then cutting and refining, so that the fineness of the jute fibers is reduced by 50%, and become ultra-fine jute fibers with a diameter of 20 μm;

[0042] (3) The fibers mixed with ultra-fine jute fibers and PLA fibers are carded for the second time and drafted for the first time to form a web;

[0043] (4) The mixed fibers that have been cross-formed by first drawing are pre-entangled by needle punching and then drawn for the second time, so that the surface density of single-fiber PLA fibers and ultra-fine jute fibers is 25g / m 2 fiber;

[0044] (...

Embodiment 2

[0046] A kind of thin jute fiber non-woven fabric for packaging, its components are calculated by weight percentage: 75% of jute fiber, 25% of PLA fiber. The thin jute fiber non-woven fabric for packaging is made through the following steps:

[0047] (1) Carry out health-preserving treatment of jute fiber;

[0048] (2) Carding the jute fibers after the health-preserving treatment, and then cutting and refining, so that the fineness of the jute fibers is reduced by 50%, and become ultra-fine jute fibers with a diameter of 45 μm;

[0049] (3) The fibers mixed with ultra-fine jute fibers and PLA fibers are carded for the second time and drafted for the first time to form a web;

[0050] (4) The mixed fibers after one-time drafting and cross-forming treatment are needled three times, and the needle punching density is 195 punches / cm 2 , the needling depth is 10mm, and the second drawing is carried out after pre-entanglement, so that the surface density of single-fiber PLA fibers...

Embodiment 3

[0053] A kind of thin jute fiber non-woven fabric for packaging, its components are calculated by weight percentage: jute fiber 68%, PLA fiber 32%. The thin jute fiber non-woven fabric for packaging is made through the following steps:

[0054] (1) Carry out health-preserving treatment of jute fiber;

[0055] (2) Carding the jute fibers after the health-preserving treatment, and then cutting and refining, so that the fineness of the jute fibers is reduced by 50%, and become ultra-fine jute fibers with a diameter of 30 μm;

[0056] (3) The fibers mixed with ultra-fine jute fibers and PLA fibers are carded for the second time and drafted for the first time to form a web;

[0057] (4) The mixed fibers after one-time drafting and cross-forming treatment are needled three times, and the needle punching density is 210 punches / cm 2 , the needling depth is 120mm, and the second drawing is carried out after pre-entanglement, so that the single-fiber PLA fiber and ultra-fine jute fibe...

Abstract

The invention discloses a thin strong-strength environment-friendly jute fiber non-woven fabric for packaging and a production method for the thin jute fiber non-woven fabric, and belongs to a non-woven material and a processing method for the same. The thin jute fiber non-woven fabric for packaging comprises the following components in percentage by weight: 65 to 75 percent of jute fiber and 25 to 35 percent of poly lactic acid (PLA) fiber. The thin jute fiber non-woven fabric for packaging is produced by the following steps of performing enzymatic treatment and primary combing on jute serving as a raw material, cutting and thinning the jute fibers, mixing the jute fibers with the PLA fibers, performing secondary combing and primary drafting crossing to form a mesh, performing secondary drafting after needling pre-entanglement, and performing a hot rolling procedure to melt, solidify and shape the PLA fibers. The thin jute fiber non-woven fabric is strong in strength and short in process flow and degradable, can be widely used for upscale shopping bags, mulching films and other packaging materials, and has broad market prospect, and the jute fibers are required to be degummed.

Description

technical field [0001] The invention specifically relates to a thin jute fiber non-woven fabric for packaging and a manufacturing method thereof. Background technique [0002] With the continuous improvement of people's environmental awareness, "green" and "environmental protection" are more and more people's attention, and more and more consumers are looking forward to the market supply of green and environmentally friendly packaging. At present, the main flexible packaging materials mainly include plastic and paper. The development direction of plastic packaging is to degrade plastics. All countries are strengthening the research on degradable plastics and accelerating the process of practical application. The output of paper products has grown rapidly, accounting for the largest proportion. Since the main source of plastic products is petroleum resources that are facing depletion, they should be recycled as much as possible. However, because the production cost of recyc...
