Description
Technical field
The present invention relates to textile technology field, especially relating to a kind of chitin fiber that adopts is the chitin yarn of raw material production and the method for producing this chitin yarn.
Background technology
Chitin is that occurring in nature is only second to the cellulosic second family macromolecule compound, generally is to extract from shrimp, crab shell.Because chitin is a kind of positively charged natural nitrogenous polysaccharide polymer, therefore also have positive charge by the chitin fiber that its processing spinning is formed, this positive charge can neutralize and have the microorganisms such as bacterium of negative electrical charge, thereby suppress bacterium it is lost activity, and reaches effect antibacterial, sterilization, prevented of the healthy harm of bacterium intrusion human body to people, and, the weaving face fabric softness that adopts chitin fiber to produce, comfortable and easy to wear, therefore, be subjected to very much liking of people.But, because the design feature of chitin itself, its fiber is thicker, and powerful special low (main cause is a porous fibre) is wet especially strong, proportion is bigger, these have determined the spinnability of chitin fiber and spinning process relatively poor, and in addition because the contained positive charge of molecule in the chitin fiber, same sex electric charge is mutually exclusive, therefore the fiber in the strip can not be embraced and be in the same place, and this has brought difficulty to spinning.Therefore, this has caused present chitin fiber to only limit to fiber blend with other kind in field of textiles, and few yarn that adopts pure chitin fiber to produce that exists, and for adopting pure chitin fiber spinning, people never have reasonable production method, and this has influenced demand and the utilization of people to chitin fiber to a certain extent; And in the chitin blended yarn that exists, the content of chitin fiber is general also lower at present, and its production performance can not satisfy people's requirement, and these have all limited further developing of chitin to a certain extent.
Summary of the invention
Technical problem to be solved by this invention provided a kind of have that good bar is done and the chitin yarn of excellent properties such as intensity to satisfy the demand of people to chitin yarn.
The present invention also provides a kind of method of producing chitin yarn, and this production method only adopts chitin fiber to produce pure chitin fiber yarn, to solve the difficulty that current people produce pure chitin fiber yarn.
For solving the problems of the technologies described above, technical scheme of the present invention provides a kind of chitin yarn, be that employing chitin kind fiber is the fine-count yarn of raw material processing, the yarn of producing index can reach 17.0～19.5, km details (50%) 400～550, km slubbing (+50%) 1100～1500, km cotton knot (+200%) 1100～1700, intensity 7.5～9.0CN/TEX, hairiness index 6～8.And the chitin kind fiber comprises chitosan (CS) fiber and/or chitin (ACT) fiber, promptly can adopt a kind of in chitosan (CS) fiber or chitin (ACT) fiber merely, use after also can adopting chitosan (CS) fiber and chitin (ACT) mixed with fibers, it is fibre length 35～40mm that chitosan and chitin fiber can adopt specification, fibre fineness 1.5～2.5D, single fiber intensity 1.53～2CN/dtex, pH value 6～7, moisture regain 15.0～15.5% is produced.And according to the situation in the actual production, the weight mixing ratio that can adopt chitosan fiber and chitin fiber is a chitosan fiber 45%, and the mixed proportion of chitin 55% is produced fine-count yarn.
Produce the method for chitin yarn among the present invention, for adopting the chitin kind fiber is that raw material is through getting the raw materials ready, blowing, comb and parallel cotton fibers prior to spinning, drafting, spinning (rove, spun yarn) and back processing chitin yarn, wherein, cotton cleaning process comprises grabs cotton, opener, gives cotton rolling operation, wherein can adopt twice opener operation, pass through the mixing and blowing machine earlier, when fiber is carried out opener, also it be carried out combing by card wire formula opener again the fiber opener; Because the chitin kind fiber strength is lower, and than great, saturation force is also low between fiber, so in whole spinning process, should adhere to following technological principle, adopt " low velocity, the strong comb, quantitatively big that divides " when being blowing, then take the principle of " low velocity, the amount of resetting, small tension receiving coil " during comb and parallel cotton fibers prior to spinning, then adopt the principle of " close setting, the big twist, low-tension, low velocity " when drafting, rove, spun yarn.
Like this, in the chitin spinning, cotton cleaning process adopts the card wire formula hired roughneck of low velocity that fiber is strengthened dividing comb under big quantitative prerequisite, and promptly the hired roughneck of opener and lapper adopts the card wire formula, and adopts mixing and blowing machine and card wire formula opener to be used the opening or cleaning of strengthening fiber; Amplify hired roughneck and the spacing of giving cotton roller and feed plate, and improve rotation speed of fan; Adopt the quantitatively big of 400～500g/m during rolling, and length adopts smaller length, prevents the web broken hole, and, sticking volume takes place easily, can in volume, adopt to fetter with kind rove bar because the fiber rolling is more fluffy.
Adopt in the carding step and before carding machine, install the cotton plate of holder additional, 290～310 rev/mins of control cylinder rotating speeds, 685～720 rev/mins of licker-in rotating speeds, 18～20 rev/mins of doffer's rotating speeds, and can give fine length with relative increase with the feed plate bed hedgehopping 6mm on the carding machine, reduce fibre damage; The branch comb that adopts spaces and is 0.2mm, 0.15mm, 0.15mm, 0.15mm, 0.2mm.
Can adopt two during drafting also, 950～1050 rev/mins of the rotating speeds of front roller, and quantitative 19.5 ± 0.5g/5m, head and adopt 1.4, two and adopt 1.2 during back area draft.And, adjust the size of head of the trumpet according to the actual conditions in producing.
Because the ratio of chitin fiber is great, the thick cross-section fibers radical of fiber number is few, adds with electric charge mutually exclusive, thereby make between fiber saturation force very little, so quantitatively answer grasp bigger than normal ripe of rove Working Procedure Controlling, generally at/5 meters of 19 grams, twist factor 75～90, regular roving feeding 5.5 ± 0.3g/10m, the grasp less than normal of machine forward pull is adjusted tension force conversion wheel, to feed tension force behind the reduction machine behind the machine, raise bar tube pallet, after reducing Speed frames, break end; The grasp less than normal of machine forward pull is breaked end to reduce before the reduction machine, roller gauge 25mm * 30mm, and apron spacing block 2.5～3.5mm, back area draft is then 1.2.
Twist factor is 370～390 in the spinning process, 9700～9900 rev/mins of spindle rotating speeds, roller gauge 18mm * 26mm, apron spacing block 2.5～3.5mm, back area draft 1.18.
The chitin kind fiber can adopt a kind of in chitosan (CS) fiber or chitin (ACT) fiber merely, use after also can adopting chitosan (CS) fiber and chitin (ACT) mixed with fibers, as to adopt the weight mixing ratio be chitosan fiber 45%, the mixed proportion of chitin fiber 55% is produced, and it is fibre length 35～40mm that chitosan and chitin fiber can adopt specification, fibre fineness 1.5～2.5D, single fiber intensity 1.53～2CN/dtex, pH value 6～7, moisture regain 15.0～15.5% is produced.
After add man-hour because the chitin fiber yarn strength is very little,, tension pulley can be removed so tension force must be little during spinning, adopt balloon controller, the bobbin package is little, for guaranteeing back processing, can incorporate a water soluble vinylon in yarn
The pure chitin yarn that the present invention produces not only has indexs such as good bar is dried, and its intensity is also better, can adapt to people's needs fully.And produce the method for pure chitin yarn among employing the present invention, its technology is simple, and is easy to operate, solves current chitin fiber and can only adopt the problem that can not purely spin with other fiber blend, and the spinning method of pure chitin fiber is provided for people.
