Description
Technical field
The present invention relates to a kind of nonwoven fabric and production method, specifically a kind of string nonwoven fabric and production method.
Background technology
Present global public hazards " environmental pollution " are more and more serious, like the application of plastic film as a kind of modern agricultural technology to increasing crop yield, increasing peasant income, promote that the development function of agricultural production is very big.But because the plastic film non-degradable has brought " white pollution " and has made soil compaction, permeability variation, degradation problem under the soil fertility.For this reason, the market development the multiple mulch film that can partially or completely degrade, like starch addition type degradable agricultural mulching, light degradation agricultural mulching, plant fiber mulch etc.And starch addition type degradable agricultural mulching, light degradation agricultural mulching still are plastics and chemical fibre because of the main raw material that adopts, and all can not eliminate " white pollution " problem in the farmland fully.Plant fiber mulch mainly is the paper mulch film, though the paper mulch film can be the environment-friendly type mulch film by decomposition, pollution-free fully in soil.But its intensity is low, wind resistance rain ability, cracky, is torn easily during the film of shop, suitable mechanical shop film.Therefore in actual use, shop film difficulty is big, takes a lot of work, and cost is higher.The patent No. is 200410022948.3; The applying date is on March 3rd, 2004; Denomination of invention is that the patent of environment-friendly type fiber crops mulch film and manufacturing technique thereof discloses a kind of numb mulch film and production method; Its method is through mixing and opening, and the flax fibre after the dedusting removal of impurities becomes net through the carding machine random web-laying equipment, and the flax fibre net that becomes the net back to form carries out chemical adhesion, the fixed film forming of drying with adhesive; Numb mulch film surface after fixed applies water repellent and carries out surface waterproofing and handle and drying again, after cold-rolling mill carries out satinage, rolling.Since bonding, the fixed film forming of drying with product is applied water repellent carries out that surface waterproofing is handled and drying will be in two steps, therefore, its complex process, operation is many, equipment investment is big (the platform number is many), the production cost height.
Summary of the invention
The purpose of this invention is to provide simple string nonwoven fabric of a kind of technology and production method.
The present invention adopts following technical scheme to realize its goal of the invention, a kind of string non-woven fabric production method, and it may further comprise the steps:
⑴ raw material is handled: with raw material dedusting removal of impurities after opening bag, mixing and opening;
⑵ become net: step ⑴ gained raw material is become net earlier after the carding machine combing, behind random web-laying equipment, become net again;
⑶ dip bonding: the raw material after becoming to net is through the dip bonding film forming, and maceration extract prepares the back in proportion by adhesive and water repellent and stirred 15 minutes～20 minutes, by weight, and 3 parts～4 parts in per 100 parts of maceration extract adhesives, 2 parts～3 parts of water repellents, Yu Weishui;
⑷ drying typing: the film of step ⑶ gained is finalized the design 130 ℃～140 ℃ of drying temperatures, criteria thus the drying time 1.5 minutes～2 minutes, 140 ℃～150 ℃ of setting temperatures, shaping time 1.5 minutes～2 minutes through drying;
⑸ satinage, rolling warehouse-in: the film of step ⑷ gained is carried out calendering through cold-rolling mill handles, after cut into and be involved in the storehouse.
Raw material described in the step ⑴ of the present invention is a kind of or its combination in ramie, jute, the cotton.
Described adhesive described in the step ⑶ of the present invention is a PVA glue, and described water repellent is a fluorine family macromolecule condensate weak cation property water repellent.
The string nonwoven fabric a kind of as above-mentioned method is produced, the heavy 30g/ ㎡ of its unit are～50g/ ㎡, thickness 0.20 ㎜～0.28 ㎜; Tensile strength 1430N/m～1600N/m; TEAR STRENGTH 50N～90N, bursting strength 150N～200N, vertical infiltration coefficient 6.0 * 10
-4㎝/s～8.0 * 10
-4㎝/s.
Because adopt technique scheme, the present invention has realized goal of the invention preferably, technology is simple, and production cost is low; The product of producing is degraded fully, and is pollution-free, helps preserving the ecological environment; Have the characteristics ultra-thin, that intensity is big, and good insulation arranged, preserve moisture, permeability, can be widely used in agricultural, industrial crops produce; The flowers, plants and trees sunshade, preserve moisture, fields such as railway, highway hillside bank protection have considerable economic and social benefit.
