Abstract
A kind of healthy hemp mat products is to be that raw material adopts appropriateness to come unstuck with the hemp, and process of fiber bundle spinning method is spun into 5-10 hempen fibres and is woven into 400-800 gram/rice with one or more strands of yarns
2The hemp mat products.The present invention is come unstuck with the bioanalysis appropriateness and special wet spinning spinning technique has solved the difficult problem that hemp tow spins, for new approach has been opened up in the utilization of hempen resource, characteristics such as hemp cloth has that absorbing sweat is done soon, mildew-resistant, fungi-proofing, anticorrosion, deodorization are particularly suitable for nice and cool property purposes, be with a wide range of applications, and can obtain tangible economic benefit.
Description
The present invention is relevant with fibre, more specifically says so about the production technology of hemp products.
Hemp is a kind of annual herb plant, mainly grows in the province such as Shandong, Henan, Anhui of northern China, is full of abundant fiber in the epidermis of the cane of hemp, its fineness is the 18-30 micron, and length is the 15-25 millimeter, and the fiber two ends are obtuse angle shape, its proportion is 1.48, is lower than other crudefiber crops.Hemp be applied in the existing very long history in China and even the world, some countries of Europe are used to tie up the optimal material of sausage with linen thread, and mainly do the raw material of making sole in China.Owing to contain impurity such as a large amount of pectin, lignin, wax in the hemp, and fiber is shorter again, therefore can't adopts modern processing method to produce more goods.
Seat is the household goods that China people generally use summer.Traditional seat be with bamboo, rattan, grass through simply being processed into, that this series products has is vexed, wet, glue shortcoming such as body.Up to the present do not see the seat that useful hemp is made as yet.Hemp has good antibacterial, mildew-resistant, deodorization, corrosion-resistant function, is a kind of natural plants very useful to the mankind.
The object of the present invention is to provide a kind of is the production technology of raw material production hemp mat products with the hemp.
The said healthy hemp mat products of the present invention is to be that raw material is spun into hempen fibre and props up thick hempen fibre by 5-10 and be woven into 400-800 gram/rice with one or more strands of by a definite form with pure hemp
2, thickness is equivalent to the hemp mat products of 2-3 millimeter, the perhaps goods that are made into the blending hempen fibre.
The production technology of healthy hemp mat comprises and comes unstuck, makes bar, rove, spun yarn, weaves and process such as arrangement.Key of the present invention is to adopt appropriateness to come unstuck and the spinning of process of fiber bundle.Its main production stage is:
1, come unstuck with the pectin decomposing enzyme appropriateness, the clearance of colloid is 70-80% in the hemp
2, the hemp through coming unstuck behind system bar and rove spinning, gives processing with a kind of bleaching liquor that boils, and makes hemp fine yarn wet spinning spinning thereafter;
3,25～28 ℃ of workshop humidity, humidity is weaved with the spinning loom of hair more than 80%;
4, weaven goods is done the primary colors arrangement in a kind of primary colors finishing agent;
5, weaven goods is done the functionalization arrangement again in a kind of functional finishing agent.
The hemp degumming method that adopts is a chemical degumming law at present, is the raw material that mainly comes unstuck with NaOH.Because chemical agent has in various degree damage to hemp, the product row yielding is low, only be about 18%, and the raffinate that comes unstuck pollutes environment.An important feature of the present invention is that hemp takes appropriateness to come unstuck.Remove the colloid of 70-80% in the hemp with pectin decomposing enzyme.The a large amount of colloids that exist in the hemp are unfavorable for big hemp spinning yarn processing, but because hemp is short, need the reserve part colloid to be used for several single staple fibres are bonded into available process of fiber again, thus among the present invention in the hemp removal efficiency of colloid be controlled at 70-80%.Utilize remaining colloid that the staple fibre of hemp is bonded into farm labourer's fibre bundle of planting.Here said colloid is meant the general name of a few class materials beyond the cellulose.Pectin is the hydroxyl and the cellulosic hydroxyl combination of virgin rubber state pectin in the hemp tissue.Between pectin and the pectin or form a kind of sub-frame between pectin and the cell membrane tissue and combine or produce other windings, we utilize some anaerobic enzyme bacterium, for example Bacillus sp-154 with these water not solubilized pectin change into water-soluble pectin or the pectin of macromolecule polyalcohol be decomposed into oligomeric carbohydrate, thereby reach the purpose of coming unstuck.The present invention adopts the pectin decomposing enzyme of ARTIFICIAL CULTURE, and addition is the 5-20% of hemp total amount, and vigor is 200 μ/ml, perhaps uses the catabolic enzyme of self-sow in the hemp.The action principle of biological degumming is as follows:
In the formula: PMGL-gathers the methyl galacturonate lyases
PGL-polygalacturonic acid lyases
PMG-gathers the methyl galacturonate hydrolase
PG-polygalacturonic acid hydrolase
The PE-pectinesterase.
Pectin decomposing enzyme under anaerobic comes unstuck, and the temperature of coming unstuck is 30-65 ℃, and PH is 7-9, and the NaOH solution that the fiber crops of will coming unstuck are at last taken out with 0.5～2% cleans, and perhaps directly water cleans the back oven dry.
The used biological inoculum of the present invention is cultivated by following step:
(1) preparation pectin decomposing enzyme culture medium its consist of: wheat bran 8-10 grams per liter, H
2PO
4The 1-2 grams per liter, wheat bran 3-5 grams per liter, MgSO
40.75-1.0 grams per liter, maize flour 5-8 grams per liter, NaOH0.35-0.45 grams per liter.
(2) culture of strains: add Bacillus SP-154 bacterial classification source in 500 liters of there-necked flasks, stirred 35-40 hour, temperature is 40 ℃ of constant temperature, and control surfactant concentration and PH=7 make its growth, and the vigor of making is the bacterial classification of 200-400 μ/ml.
(3) breeding of bacterial classification: above-mentioned mother liquor is injected the round of 15000 liters, and 40 ℃ keep constant temperature down, stir 24-36 hour, and the vigor that can obtain is the bacterium liquid of 200-250 μ/ml.
Another important feature of the present invention is that big hemp spinning yarn is a kind of process of fiber bundle spinning.Hemp after coming unstuck, after system bar and slubbing, need give processing because hemp impurity is many with a kind of bleaching liquor that boils, Fiber Distribution is inhomogeneous, improve confficient of static friction between the hemp by boiling chemicking, softening fibre, the brute force of fortifying fibre, the said bleaching liquor that boils is a kind of dielectric solution that contains bleeding agent, softener.It forms content: NaCO
3The 2-3 grams per liter, LMB bleeding agent 1-1.5 grams per liter, worker employed in a plant nursery's softener 2.5-4.8 grams per liter, Na
2PO
41.5-2.0 grams per liter.The hemp rove is through this wet spinning spinning that carries out hemp fine yarn after boiling chemicking.
It is that seat after weaving also needs further to do primary colors arrangement and finishing functions that the present invention also has an important feature.The purpose of primary colors arrangement is to remove the lignin, the ash that are mingled with in the hemp impurity that grades, and shows the true qualities of hemp.The constituent content of used primary colors finishing agent is: boiling-off additive KRD-1 1-3g/L, extractant KRD-2 1-3g/L hydrogen peroxide stabilizer KRD-3 2-6g/L, penetrating agent JFC 0.5-1g/L hydrogen peroxide stabilizer C-83 5-8g/L, H
2O
22-6g/L, NaOH10-20g/L.Treatment temperature is 40-95 ℃.
The functionalization arrangement is to carry out in a kind of functional finishing agent, and said functional finishing agent is a kind of ammonia or ammonium salt.Because NH
3Molecule is less, can be impregnated into fibrous inside formation hydrogen bond and make swelling of fiber, thereby suffered internal stress and the distortion of fiber in the numb seat processing that relaxed makes product size be stablized that rigidity increases, and elasticity improves, and washable, nonshrink crease-resistant.
By the ammonia arrangement, make the flax fibre aggregated structure more help moisture pick-up properties.Because the noncrystalline domain merchant of fiber becomes increase after treatment, fiber amorphous region vector reduces, and the degree of orientation that strand produces and the rigidity of long-chain molecule self become big, and hygroscopicity is strengthened.There is stronger polar group in addition in the fiber molecule, caused stronger wettability power.After tested, handle the wet speed of loosing of back hemp mat products, have the hysteresis quality of moisture absorption, make product have absorbing sweat, do effect soon, be particularly suitable for nice and cool property purposes greater than moisture absorption speed.
Because the polar group on the fiber molecule is because of (NH
2) and strengthen, thereby the fibrous body heat conductivility is improved.Simultaneously between the fiber, stress is eliminated between yarn and the yarn, makes it to arrange more to become rationally, has improved the gas permeability of hemp mat products, the distributing of the heat of being more convenient for.
With an example production technology of the present invention is described further in conjunction with the accompanying drawings more below.
Accompanying drawing 1 is hemp mat products technological process of production figure of the present invention.
1 is hemp biological degumming among Fig. 1, the raw ramie of hemp is lashed put into the container that clear water is housed, and adds the saccharomycete of the heavy 1-5% of fiber crops, and the water transfer temperature is to 20-35 ℃, and PH=5-7 is incubated 24 hours, has at this moment caused the anaerobic bacteria growth conditions.Add cultured pectin decomposing enzyme bacterium liquid, vigor is 200 μ/ml, and addition is that the heavy 5-20% temperature adjustment of fiber crops is to 30-65 ℃, PH is 7-9, reacts 6-12 hour, and the fiber crops of will coming unstuck are then taken out, NaOH solution with 0.5-2% cleans earlier, cleans to the oven dry of neutral back with clear water again.
Hemp after coming unstuck through system bar, slubbing yarn, gives processing with boiling bleaching liquor again, and wet spinning thereafter becomes 5-10 to prop up spun yarn, perhaps is spun into other blended yarns.At workshop temperature 25-28 ℃, humidity is woven into numb mat products with the spinning loom of hair more than 80%.Fabric was handled 2-3 hour in 40-95 ℃ primary colors finishing agent, made functionality with liquefied ammonia at 33.7 ℃ again and handled, in 100 ℃ of oven dry down.Product detects through national quality of textile products supervision and inspection center, and hydroscopicity is 7.43mg/min, and the wet rate of loosing is 12.6mg/min.Through Microbiology and Epidemic Disease Inst., Academy of Military-Medical Sciences (C,,, and wash the back bacteriostatic test in addition to hemp textile without any drug treating by the qualitative bacteriostatic method of U.S. AATCC90-1982.Result of the test shows the hemp mat products to staphylococcus aureus, pseudomonas aeruginosa, Escherichia coli, and Candida albicans all has certain fungistatic effect, illustrates that this product has fungi-proofing, mildew-resistant, deodorization, anti-corrosion function.
Advantage of the present invention is clearly, and the hemp biological appropriateness is come unstuck and process of fiber bundle spinning technique, has overcome the short defective of hemp, makes this short fiber utilization of resources become possibility. Succeeding in developing of hemp seat, not only class new varieties have been increased for traditional mat products family, the production technology that proposes by the present invention also can be produced fabric in various summer, spring and autumn fabric, suit facing material and hemp grass cloth, canvas, denim etc., for the new varieties of exploitation hemp products have been opened up bright prospects.
