Roller in device makees 2 smooth treatments using coating (such as can be using conventional AB dual-component coating), to reduce viscous twine
Phenomenon.
S6, rove:
The Roving Frames using longitude and latitude weave A186F fly frame, process of roving preferably use " again pressurization, low velocity, reset
The technological principle of amount, small tension receiving coil ", so that thick Yarn Evenness is uniform.The good elongation of Roving Frames priority control, elongation require control
System is in 1.3% range, and front and rear row, big small yarn difference are in 0.5% range.Continuous rove is principle when roving twist factor is to unwind
It is as small as possible, guarantee the normal drawing-off of spun yarn.
The main technologic parameters of rove step are as follows: roller gauge 33mm × 48mm, nip gauge 7.5mm, roving twist factor
86, ingot speed 720r/min.
S7, spun yarn:
The spinning process use the thin compact spinning frame of Ma Zuoli (East Platform) DTM129 type, spinning process mainly with reduce at
Yarn hair plumage, raising strip dry CV value, reduction details, slubbing are attached most importance to.Resultant yarn filoplume can be reduced using compact spinning technology, improves resultant yarn
Strongly.
The concrete technology of the spun yarn step is configured that ingot speed 14000rpm, back zone drafting multiple 1.21, roller gauge 30mm
×48mm.Select band press bar distance clip, nip gauge 5.0mm, twist factor 415.In the selection of special part: low hard using 65 degree
Elastomeric rubber roller is spent, evenness fault value is reduced；The stronger alloy steel collar PG14254 steel of self-lubricating function is selected in twisting part
Neck；The W321 fashioned iron wire ring that wire loop selects highly polished wearability good.
S8, winder:
Using German Schlafhorst AC338RM automatic winder, the configuration of winding procedure is mainly the choosing of the clear technique of electricity
It selects, not only guaranteed that harmful yarn defect can be removed but also guarantees certain running efficiency.The technological principle of small tension receiving coil, low velocity is selected, automatically
The air pressure of connector, air splicer wants sufficient, and workshop relative humidity is controlled 65%.The clear technique of electricity: N300%, S140% ×
1.8cm, L30% × 40cm, T30% × 70cm.Winder speed 800m/min, cotton knot 6.0.
The performance indicator for the high-tenacity flame-retardant yarn that the production technology of the flame-retardant yarn of embodiment 1 prepares see the table below 7:
The performance indicator of the flame-retardant yarn (32S) of 7 embodiment 1 of table
| Test index | Index value |
| Hundred meters of weight variation coefficient CV% | 2.2 |
| Practical dry weight (gram/100 meters) | 1.72 |
| Hundred meters of deviation of weights (%) | 1.6 |
| Actual number (spy) | 18.6 |
| Regain (%) | 8.2 |
| Single thread breaking strength (cN/tex) | 16.2 |
| Amendment strength (cN) | 294.8 |
| Single yarn strength CV CV% | 11.5 |

As can be seen from Table 7, the superelevation strong inflaming retarding yarn that the production of embodiment 1 obtains has anti-flammability high, and intensity is big.It should
The fabric combustibility of flame-retardant yarn reaches B1 grades of standard of national standard GB 17591-2006 " fire-retardant woven fabric ", and each physical index reaches
The excellent level of national standard GB/T406-2008.
Significantly, since institute's spun yarn is combined by four component fibers, mixed uniformity determines spinning yarn quality
And the comprehensive performance of final garment material.Each fiber must be sufficiently mixed, and just can guarantee the uniformity and consistency of its resultant yarn.It passes
There are two types of the textile fabric hybrid modes of system: the mixing of cotton slot and drafting mix.Due to having in aryl synthetic fibre conductive fiber production process
Electrostatic phenomenon is not easy individually at item, in addition dosage is small, it is mixed to be unsuitable for item.If the damage using the coiled method of twice, to fiber
It is larger.
The present invention using mixing machine mix, mixing machine mixing after, before rear road spin each process be mixed into main task into
Row operating process, cotton roll number, in trough, slot, in slot, the collocation of slot tail cotton roll laterally used on carding machine, to drafting with arranging
Cotton slivers of carding machine is same at a glance for drafting, while falling two head draftings of bucket to end and for at a glance.As far as possible from raw material
Investment and entire production process consider that the mixing between fiber is abundant.Simultaneously sum number increases various processes, and weight increases, to lead greatly
Based on stretching, increase sliver uniformity.
In addition, it is worth noting that, the present invention is by all kinds of fire resistance fibre mixtures, according to flame retardant effect, comfort, strength
The indexs such as index, molten drop situation determine: based on anti-flaming viscose, being equipped with high temperature resistant, high-strength p-aramid fiber 1414 and fit
The high-strength polyamide fibre and anti-flaming viscose of amount improve feel and interfibrous concertedness, then the aramid fiber base conductive fiber that adapted is a small amount of, will
The control of finished product electrostatic phenomenon is being taken in critical field, produces 32 high wearability flame-retardant yarn to meet ready-made clothes items
Performance requirement.Research discovery through a large number of experiments: when flame-retardant yarn is by 56%-64% flame retardant viscose fiber, 23%-31% pairs
It is existing good on the whole when position Fanglun l414,6%-14% polyamide fibre and 2%-6% aramid fiber base conductive fiber are mixed and processed
Fire-retardant, heat-proof quality, and have excellent comfort, it can be used as high-intensitive protection and take yarn.
When the proportion of flame retardant viscose fiber in flame-retardant yarn, p-aramid fiber 1414, polyamide fibre and aramid fiber base conductive fiber is super
Out when above range, then high-intensitive flame-retardant yarn can not be obtained.Since anti-flaming viscose monofilament strength is lower, dosage increases yarn
Line strength is decreased obviously；Aramid fiber properties are preferable, but dyeability is poor, are more than time ratio, fabric not easy coloring；Brocade
Synthetic fibre is since fire-retardant rank is lower, and only slightly flame retardant effect, dosage increasing will affect fabric and hinder whole fuel efficiency fruit；Conductive fiber,
It is expensive, electric conductivity can be met using 2-3%.
Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, all should be considered as described in this specification.
The embodiments described above only express several embodiments of the present invention, and the description thereof is more specific and detailed, but simultaneously
It cannot therefore be construed as limiting the scope of the patent.It should be pointed out that coming for those of ordinary skill in the art
It says, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to protection of the invention
Range.Therefore, the scope of protection of the patent of the invention shall be subject to the appended claims.
