Problems solved by technology

No solid medium does not fix plants well, plants can only grow in liquid
Ordinary solid media have poor air permeability and water permeability, which can easily cause plant root rot; or some solid media have relatively low strength and cannot support the growth of plants with developed root systems, or have a short service life and are prone to aging

preparation example Construction

[0033] ginseng figure 1 As shown, the invention discloses a preparation method of a high-strength low-stretch plant planting blanket, comprising:

[0034] S1, carding the mixed fibers into a single-layer fiber web, and the carding is carried out in a carding machine;

[0035] S2, performing pre-acupuncture reinforcement on the combed single-layer fiber web, and the pre-acupuncture reinforcement is carried out on a pre-acupuncture machine;

[0036] S3, performing acupuncture reinforcement on the multi-layer pre-acupuncture reinforced fiber web to obtain a nonwoven fabric, and the acupuncture reinforcement is performed on the main acupuncture machine;

[0037] S4, composite the non-woven fabric with the single-layer polypropylene fabric to obtain figure 2 The plant planting blanket shown is composed of a nonwoven fabric (mixed fiber mesh layer) 1 and a polypropylene fabric layer 2 .

[0038] The upper layer of the planting blanket is processed by needle-punching of fiber mat...

Embodiment 1

[0047] In this embodiment, the mixed fibers are firstly carded into a web in a carding machine.

[0048] In the mixed fibers, the first fiber is polyester fiber, the second fiber is cotton fiber, the third fiber is polyacrylonitrile fiber, and the mass ratio of the first fiber, the second fiber and the third fiber is about 5:4:1.

[0049] Lay the mixed fiber web that has been carded in multiple layers, and then enter the pre-needling machine with a punching density of 50 punches / cm 2 ; Acupuncture depth is 4mm; Acupuncture frequency is 300 times / min.

[0050] Lay 2 to 6 layers of the pre-needled fiber web and then enter the main needling machine at a needling depth of 8mm; the needling density is 160 punches / cm 2 ;Acupuncture frequency of 400 times / min is reinforced into a planting blanket.

Embodiment 2

[0052] In this embodiment, the mixed fibers are firstly carded into a web in a carding machine.

[0053] In the mixed fibers, the first fiber is polyester fiber, the second fiber is cotton fiber, the third fiber is polyacrylonitrile fiber, and the mass ratio of the first fiber, the second fiber and the third fiber is about 5:4:1.

[0054] Lay the mixed fiber web that has been carded in multiple layers, and then enter the pre-needling machine with a punching density of 50 punches / cm 2 ; Acupuncture depth is 4mm; Acupuncture frequency is 300 times / min.

[0055] Lay 2 to 6 layers of the pre-needled fiber web and then enter the main needling machine at a needling depth of 8mm; the needling density is 160 punches / cm 2 ; Acupuncture frequency 400 times / min reinforcement.

[0056] Then the needle-punched fabric and the polypropylene fabric with a thickness of 2mm are needled at a depth of 8mm; the needle density is 160 punches / cm 2 ; Acupuncture frequency 400 times / min reinforceme...

Abstract

The invention discloses a high-strength and low-extension plant cultivation carpet and a preparation method of the plant cultivation carpet. The preparation method comprises the steps of: S1, hecklingmixed fibers to form single-layer fiber nets, S2, pre-needling and reinforcing the heckled single-layer fiber nets, S3, needling and reinforcing the pre-needled and reinforced fiber nets to form a nonwoven fabric, and S4, compounding the nonwoven fabric and a single-layer polypropylene fabric to form the plant cultivation carpet. The fibers in the fabric are arrayed very disorderly and irregularly after needling and reinforcement, so that many flexural pores exist in the fabric to facilitate extension of plant roots; through compounding with the polypropylene fabric after the needling and reinforcement, the cultivation carpet can obtain more excellent mechanical properties; after compounding with the polypropylene fabric, the fabric becomes the high-strength and low-extension plant carpetmore suitable for plant growth; a production technology is simple and short in procedure; the fibers used are reclaimed fibers; the cost is lowered; resource waste is reduced; and the carpet is environmentally friendly and pollution-free.

Description

technical field [0001] The invention relates to the technical field of soilless planting blankets, in particular to a high-strength and low-elongation planting blanket and a preparation method thereof. Background technique [0002] In today's society, as the urbanization process is getting faster and faster, the population is increasing, more and more land is occupied by homesteads, and most of the roads have changed from dirt roads to cement and asphalt roads. The per capita arable land is getting less and less, and the arable land at this stage can only meet the production of crops. Especially in cities, the cultivated land that can be used in the city is even more scarce, resulting in the scarcity of green plants in most of the cities, causing problems in the entire ecological system in the city, and the air environment in the city is becoming more and more serious. worse. [0003] In order to change this situation, many soilless cultivation techniques have appeared now...
