Summary of the invention
The invention provides a kind of preparation method of fragrant towel, fragrant fiber yarn chosen by this towel and cotton fiber yarn carries out blending, the yarn count feature different for two kinds of yarns formulates rational blending pattern, the yarn weaving using fragrant fiber yarn and cotton fiber blending to make goes out a kind of towel of mannerism, because the aromatic that have employed containing plant flavour not only makes people feel to be in a cheerful frame of mind in this towel, also there is the function of fragrant health care.
The present invention is by the following technical solutions: a kind of preparation method of fragrant towel, comprise yarn composite spinning, base towel weave and weave after knop cloth Final finishing process, wherein said yarn comprises the step such as drafting, slubbing, described Final finishing process comprises the steps such as dyeing, polishing, oven dry, sewing, compared with prior art, the present invention is have selected special pulp furnish and technique at yarn, specific as follows:
Spices master batch and terylene spinning liquid are mainly carried out by weight 1:100 that composite spinning makes by fragrant fiber first of the present invention, spices and sandwich layer copolymer binding strength high, and substantially can not through fibrocortex, but along fiber longitudinally from cross section effusion, reach lasting fragrance effect.Spices master batch and terylene spinning liquid carry out composite spinning by weight 1:100, be because: spices master batch addition crosses that I haven't seen you for ages and affects the persistence of fragrance and functional, and addition too much can increase cost.Wherein, spices master batch also has different health care except having fragrance, selects different plant perfume master batch according to difference in functionality, and as lavender spices master batch energy keeping tensions down, aloe spices master batch can antibacterial, the rose master batch energy relieving fatigue of moisture absorption etc.
In addition, the present inventor's yarn that blending obtains under this proportioning, ensure that finally can adopt the yarn of blending gained obtain qualified have goodly cross long-felt test, when determining blending, the consumption weight ratio of fragrant fiber and cotton fiber is 4:6.
Because fragrant fiber of the present invention is terylene carrier, easily produce electrostatic, spinning process should avoid fibre damage, needs to control hired roughneck blow speed, according to the technological principle of " light quantitatively, slow train fast ", reduces the generation of cotton knot, improves yarn quality.The change of conservative control humiture in process, should adjust the humiture in workshop in time according to external condition and raw material moisture regain, reduce the generation of electrostatic, prevent the problems such as sticky volume, lap-ups, comprehensive above-mentioned consideration, inventor determines that the parameter of blending is as follows:
(1) mixed cotton: in order to ensure yarn quality, on raw material is selected:
The physical index of cotton fiber: length 30mm, mark grand 4.1, maturity coefficient 0.9, short fiber index 9.3%; The physical index of selected fragrant fiber: length: 38mm, fineness: 1.5DX, fracture strength 3.08cN/dtex;
(2) opening and cleaning step: because fragrant fiber regularity is good, containing assorted less, comparatively ordinary polyester short fiber is low for brute force, therefore, we take many combs to beat less at opening and cleaning step, specific as follows to comb the technological measure that generation beats: cylinder 360, licker-in 803, cover plate 240, feed plate 5-12, licker-in ~ cylinder spaces 0.18mm, cylinder ~ Flat Gauge 0.31mm, 0.26mm, 0.26mm, 0.26mm, 0.31mm, cylinder ~ doffer is spaced 0.14mm;
Quantitative 20.5 cylinders 326 of FA231, licker-in 674, cover plate 79, feed plate 5-12, licker-in ~ cylinder spaces 0.18mm, cylinder ~ Flat Gauge 0.36mm, 0.28mm, 0.28mm, 0.28mm, 0.36mm, and cylinder ~ doffer is spaced 0.16mm;
(3) mixing in doubling step: for ensureing that two kinds of fibers are mixed evenly, of the present invention and strip adoption three road also closes technique, take into account the performance of fragrant fiber and cotton fiber like this, adopt space greatly, heavily pressurize, the lighter technology measure such as quantitative, the control of Reasonable adjustment pressure bar to fiber prevents drawing-off from littlely to open, goes out " hardhead ", because fragrant fiber is more fluffy, suitably control the pressurization of output press roll, prevent the fluffy blocking horn mouth of strip.Mixing in doubling step technological parameter is as follows:
(4) Roving Frames: because fragrant fiber is more fluffy, cohesive force is poor, take into account the flexible nature of towel products, the present inventor adopts lighter quantitative and lower twist factor, and adopts less roller gauge, larger nip gauge, prevents and leads inextensible phenomenon; Adopt the technological measure such as heavier pressurization and less spinning tension, to improve extended parallelization and the bar evenness of fiber, reduce yarn defect.For reducing rove filoplume, selecting the false twister with down scale, improving false twisting effect; Determine following parameter:
Roving Frames technological parameter: regular roving feeding 4.8g/10m, twist factor 110, ingot speed 800r/min, roller gauge 9mm × 24mm × 32mm, Pullin performances back area draft 1.28 times, total draft 7.9 times;
(5) spinning process: because fragrant fiber electrostatic phenomenon is serious, for reducing spinning end breaking, suitably reduce front roller speed, spun yarn adopts less back zone drafting multiple and larger back area draft to space, to obtain good bar evenness, design parameter is as follows:
Spinning process technological parameter: front roller speed 210r/min, roller gauge (front × rear), 18mm × 27mm, back zone drafting multiple 1.17 times, twist factor: 330;
(6) winding procedure: in order to excise some cop faults, improve follow-up work efficiency, design parameter is as follows:
Luo Lian street device 3,8,4, clearing thresholding N:5.5, DS2.1, LS1.3, DL1.3, LL20, D30, L-30 twist with the fingers knot thresholding N2.1, LS1.3, DL1.3, LL15, D20, L30.
Blending the blended yarn taking into account fragrant fiber yarn and cotton fiber characteristic can be obtained after determining above-mentioned technological parameter, following mode can be adopted afterwards to carry out base towel weave, specifically select above-mentioned blended yarn as hair warp, select 52-64# reed, filling density selects 150-190pcs/dm to weave, to ensure feel and the style of base towel.
And in described Final finishing process, inventor finds the characteristic in order to ensure fragrant fiber, need to carry out larger adjustment to polishing process, the acid polishing of general employing in prior art, but the large macrolesion fragrant fiber of meeting after adopting this technology, its characteristic is lost substantially, in order to avoid this situation, inventor finds that after long term test this polishing can be carried out in neutral conditions, the condition selected is pH=7, neutral polishing enzyme dosage: 2wt%, polish temperature: 60 degree, the polishing time: 90min, the neutral polishing enzyme wherein adopted is that Novi believes neutral polishing enzyme H8001.
Arrange through sewing again after above-mentioned Final finishing and can obtain shaping towel products, and the towel fragranced persistence adopting said method to obtain is long, really brings happy enjoyment to people and regulates the effect of spirit.
Detailed description of the invention:
