Abstract
The invention discloses flame-retardant yarn and a production process. The flame-retardant yarn is mainly prepared from 30% of flame-retardant modal, 28% of acrylic polyvinyl chloride fiber, 116% of Tencel, 13% of para-position aramid fiber, 11% of polyamide and 2% of antistatic fiber. A manufacturing method includes the following steps of blowing, cotton carding, drawing, roving, spinning and spooling. Lenzing FR fiber is adopted in the MP-185 six-component flame-retardant yarn and gives fabric excellent flame retardance and wearing comfort, tencel fiber of a small ratio is adopted so that the fabric can be higher in comfort, and besides, the para-position aramid fiber and high-strength polyarmide fiber are adopted to make the fabric have excellent physical strength and wear resistance; the flame-retardant fiber and the non-flame-retardant fiber are mixed to generate a synergistic effect, so that the yarn is excellent in flame retardance.
Description
Technical field
The present invention relates to a kind of yarn manufacture method, especially a kind of MP-185 flame-retardant yarn manufacture method.
Background technology
Blending chemical & blended fabric is chemical fibre mixes, with the natural fiber such as other cotton wool, silk, fiber crops, the textile product that spinning is made into, its feature is not only to highlight the style of terylene but also have the strong point of bafta, in the case of dry, wet, elasticity and wearability are preferable, there is dimensionally stable, the advantage that washing shrinkage is little, also have tall and straight, be difficult to fold, washable, quick-drying feature.Existing combed cotton is fabricated to the fabric that yarn weaving gets, and is smooth to the touch, comfortable and easy to wear, is especially suitable for making high-grade clothing.But, the development built along with urban modernization, the difficult burning of people's textile requires more and more higher, in many fire incidents, the consequence caused because of textile combustion is the most serious, for this, a series of relevant laws and regulations have been formulated in countries in the world, the fire resistance of the textile that special population or occasion use is proposed restricted technology requirement, and combed cotton belongs to cotton fiber, the restriction of own material causes so by the yarn that combed cotton is raw material making, and maximum shortcoming is inflammable, it is impossible to use as fire proofing.On the other hand, along with the socioeconomic growing and raising of living standards of the people, and the continuous renewal of people's consumption idea, quality of life and living environment are increasingly paid attention to, more and more higher to the Functional Requirement of clothing, the requirement of the aspects such as particularly fire-retardant to clothing, feel, quality the most constantly improves.
At present, fiber yarn and the kind of fabric on the market are a lot, mainly there are fire resistance fibre yarn and fabric, and flame-retardant yarn generally spins or scribbled based on the pure fibers such as aramid fiber, flame-resistant terylene, although the fire-retardant domestic animal energy of this kind of yarn also can reach country's flame-retardant standard, but the flame retardant effect of portioned product is the best, particularly chemical fibre fire proofing, its dropping temperature produced after running into fire is higher, can scalded skin, therefore as fabric for people's daily life or the most undesirable preventing fires, in fire-fighting.
Additionally, flame-retardant yarn in the market be two or three kind of fire resistance fibre blending form, by these yarn weaving fabric exist difficulty dyeing, wearing comfort difference etc. problem；MP-185 six component flame-retardant yarn is then made up of fire resistance fibre in six and non-flame resistant fiber, and the cooperative effect of various fibers makes the fabric become by this yarn weaving have the anti-flammability of excellence, the most comfortable taking and durable practicality.
Summary of the invention
Prior art can not meet the needs of people, not enough for making up prior art, it is desirable to provide a kind of MP-185 flame-retardant yarn manufacture method.
For achieving the above object, the present invention by the following technical solutions: a kind of MP-185 flame-retardant yarn manufacture method, its primary raw material and proportioning thereof be: fire-retardant Modal 30%, fine polyvinyl chloride fibre 28%, Tencel16%, p-aramid fiber 13%, polyamide 11%, antistatic fibre 2%；Its making comprises the following steps, and step one is blue and white；Step 2, comb and parallel cotton fibers prior to spinning；Step 3, drafting；Step 4, rove；Step 5, spun yarn；Step 6, winder；
Wherein in step one: blowing: sent into by raw material in blowing equipment, raw cotton carrying out careful shredding, remove fine impurities, make the uniform lap conformed to quality requirements, design parameter is as follows: lap weighs 18kg surely.
In step 2 comb and parallel cotton fibers prior to spinning: through the lap of blowing, enter carding step, fibre bundle is completely decomposed into single fiber, remove and remain in fine impurities therein, make uniform cotton sliver, meet later process requirement.For ensureing card sliver quality, reduce the damage of fiber in carding process, use the technological principle of " light quantitative, jogging speed ", suitably reduce licker-in doffer speed, increasing cylinder and licker-in surface speed ratio, doffer wants big with the rate of transform of cylinder, reduces fiber and fills, rubs, increase combing transfer, reduce the generation of cotton knot；In order to guarantee to reach requirement, the design parameter employed in this step is for producing quantitative 15g/5 rice, cylinder rotating speed 330r/min, licker-in rotating speed 690r/min, big speed 25r/min in road, cover plate speed 79mm/min.
In step 3 drafting: the carded sliver long term irregularity that comb and parallel cotton fibers prior to spinning is fabricated to is higher, deviation of weight is bigger, and the extended parallelization of fiber is poor, fiber alignment is disorderly, major part fiber becomes crotch or case of bending, there is also fraction flock simultaneously, so, need through mixing in doubling step, the carded sliver is processed further ripe bar, to improve cotton sliver quality；The technique that mixing in doubling step is concrete:
| And close number of channels | Combined roots | Ratch (in front * after *) | Back zone traction multiple |
| Slubbing | 6-7 root | 50-65*52-54*56-65mm | 1.9-2.1 |
| Two roads | 7-8 root | 50-65*52-54*56-65mm | 1.5-1.8 |
| Three roads | 7-8 root | 50-65*52-54*56-65mm | 1.5-1.8 |
In step 4 rove: the drawing-off ability of ring spinning frame not yet reaches to use the requirement of the direct resultant yarn of ripe bar, so needing rove I sequence to a part of drawing-off undertaking in spinning process.Major parameter configuration is as follows:
| Regular roving feeding | Back zone drafting multiple | Ratch (after front *) | Roving twist factor |
| 4.0-6.5g/10m | 1.15-1.45 | 60-63*70-74mm | 75-85 |
In step 5 spun yarn: obtaining cop, spinning process is to be spun into rove to have a routing density, certain package, and meets the spun yarn of quality standard or customer requirement, for twisting thread, weaving.Design parameter is as follows:
| The actual sequence number of spun yarn | Back zone drafting multiple | Ratch (in front * after *) |
| 9.8-60tex | 1.2-1.4 | 52-55*60-65 |
| Twist factor | Wire loop | Ingot speed |
| 340-360 | 6905 | 13500-16000r/min |
In step 6 winder: in order to obtain finished product, winding procedure is that yarn defect removed further by the cop made by spinning process, it is thus achieved that molding bobbin, and wherein bobbin weight is 1.6kg/ cylinder.
Compared with prior art, the invention has the beneficial effects as follows: this MP-185 six component flame-retardant yarn have employed Lenzing FR fiber and gives the excellent anti-flammability of fabric and wearing comfort, and the tencel fiber that have employed again small scale makes fabric have more excellent comfortableness；Separately have employed p-aramid fiber and high-strength Fypro and give the excellent physical strength of fabric and the performance such as wear-resisting；Utilize fire resistance fibre to mix non-flame resistant fiber, produce cooperative effect and make yarn have the anti-flammability of excellence.
