Description
Technical Field
The invention relates to the technical field of textile yarns, in particular to a processing technology of semi-worsted plush core-spun yarns.
Background
Semi-worsted is a novel spinning technology which is developed by independent innovation technology of wool spinning industry in China between wool spinning and roving. The semi-worsted fabric has short processing flow and good product benefit; the processing raw materials have strong adaptability and are suitable for blending of different fibers; can overcome the technical difficulty of high count in animal fiber spinning, and greatly develops the production scale and the production technology. However, semi-worsted spinning technology has defects, mainly because the fiber damage is large in the processing process, the strength, the yarn evenness level, the hairiness index and the pilling resistance of the yarn are reduced. The core-spun yarn is formed by compounding elastic filaments in short fibers through special equipment and a special process, so that the product has excellent weaving strength and tensile resilience, the yarn evenness level is improved, and the core-spun yarn has a great effect on improving the defects of semi-worsted products. However, the semi-worsted core-spun yarn product has large fiber damage in the processing process, and the problems of poor coating of the medium-high count product on filaments and the like still remain the main problems which are puzzling the product to gain market acceptance.
Disclosure of Invention
The invention aims to solve the technical defects and provide a processing technology of semi-worsted plush covering yarns, which reduces the damage to fibers in the processing process.
In order to achieve the purpose, the invention designs a processing technology of semi-worsted plush covering yarn, which comprises the following steps:
firstly, selecting raw materials: the wool fabric is composed of 50-80% of 90S bayonan wool, 10-30% of cashmere and 10-20% of polyester fiber filaments, and the total mass ratio of the raw materials is 100%;
step two, a carding procedure: carding by using a wool spinning roller type carding machine;
step three, a needle combing procedure: a wool spinning gill box is adopted for gilling;
step four, roving: adopting twistless roving equipment;
fifthly, spinning: the core-spun yarn is spun by a spinning machine provided with a spinning core-spun yarn facility.
In the above technical scheme: the second step of carding: the carding process is carried out by changing the cover plate type carding machine adopted in the prior art into a wool spinning roller type carding machine. The hard grip with great damage to the fiber is changed into the elastic grip suitable for the low-strength and easy-to-comb fiber such as wool, velvet and the like.
The carding machine comprises a hair bucket, a licker-in, a pre-carding cylinder, a main cylinder, a doffer and a hair stripping device which are arranged on a frame in sequence; the pre-carding system with three groups of working rollers and a hair peeling roller combination is arranged on the pre-carding cylinder, a transfer roller is arranged between the pre-carding cylinder and the main cylinder, and a cover plate is arranged on the main cylinder. Compared with a carding machine, the feeding roller holding is elastic holding, a pre-carding system with 3 pairs of working rollers is added, carding cover plates are reduced from 106 to 84, a main carding system adopts 30 working cover plates, and four-point distances of the cover plates are respectively 9, 10 and 12 English filaments. Compared with a carding machine, the rotating speed of the cylinder can be reduced by 100 revolutions per minute, the carding is softer, and the fiber damage is less.
The carding process takes the main fiber of the raw material as a selection basis, and the technological parameters are set as follows according to the main fiber length of 45-50mm of the raw material: a group of working rolls and hair peeling rolls close to the licker-in are a first group, a group of working rolls and hair peeling rolls close to the main cylinder are a third group, and a middle working roll and a middle hair peeling roll are a second group; wherein the gauge of the working rolls in the first group is 20-22 English silk, the gauge of the hair peeling roll is 21-22 English silk, the gauge of the working rolls in the second group is 18-20 English silk, the gauge of the hair peeling roll is 22 English silk, and the gauge of the working rolls in the third group is 16-18 English silk, and the gauge of the hair peeling roll is 22 English silk. Big gauge distance is combed in advance the fibre of restrainting form, forms more tiny restrainted fibre, makes the fibre change the carding, reduces the fibre damage that the carding leads to, can make fibre length improve 5mm to short staple content has been reduced, has played important effect to promoting the yarn quality.
Step two, a gilling process: the cotton spinning drawing frame is changed into a wool spinning gill box. The method adopts a combination form of two faller gill machines and two bubble roller gill machines, wherein one needle and two needles are the faller gill machines, and three needles and four needles are the bubble roller gill machines, so that the problem of long fiber breakage caused by forced holding and drafting in the roller drafting device process of the traditional drawing process is solved. Choose for use little compass gill box, can effectively reduce the draft distance (can adjust to 24mm to minimum), be applicable to the fibre length of this application product, enable that the fibre is more straightened, parallel, the resolution improves, and for elasticity grips, reduces unexpected draft, promotes the evenness level, and can not the stretch-break fibre. The bubble roller gilling machine adopts the process principle of 'small gauge, multiple combination, small drafting and small tension', and the weight CV of the cooked sliver is controlled within 1.5 percent.
Step three, roving: compared with the roving produced by the twistless roving frame, the roving produced by the twistless roving frame has larger width of strands discharged from a jaw before spinning, and the twistless roving frame has good improvement effect on solving the problem of poor filament coating of the core-spun yarn. Adopting twistless roving equipment and slightly smaller adjustment of drafting gauge (front zone 25mm, total gauge 110 mm); the draft multiple is designed to be smaller and is controlled to be between 5.5 and 7.5 times; the tension of each yarn guide area is adjusted to be 1X; the buncher is selected to be small in size, so that the fiber cohesive force is increased; the speed of the rubbing plate is increased to 110-120m/min, so that the roving is provided with higher false twist, and accidental drafting is prevented. The yarn evenness is controlled below 5%, and the weight unevenness is controlled below 1.0%.
The fourth step: spinning: the polyester fiber filament is conveyed by two feeding rollers with the same speed as the front roller of the spinning frame and is regulated to 1.06-1.1 in the speed limiting ratio of the front roller and the feeding roller via the yarn guide wheel installed over the front leather roller. The polyester fiber filament is regulated at the center of the spun yarn strip outlet by a yarn guide wheel.
The processing technology of the semi-worsted plush core-spun yarn effectively solves the problems of large fiber damage, high short velvet content, poor yarn levelness and the like in the processing process of semi-worsted plush products. Meanwhile, the problem of poor filament coating of the high-count product in the semi-worsted core-spun product is also improved.
