Melanzhoza. Mixing bands in worsted spinning. | Engineering, technical sciences, materials, papers, development
In worsted spinning mill production materials are mixed most of the bands. It is implemented as a homogeneous the fake boys material (wool - wool, chemical fiber - chemical fibers) and heterogeneous (wave - chemical fiber blend of multicolored) The mixture of materials of the bands leads to a very good homogenization of the spinning batch.
Mixing of the strip and the formation of a homogeneous mixture is one of the most important operations that are performed by the technologist. It depends on both the normal flow of the entire predpredachen and spinning process and quality characteristics of the yarn.
To be able to design the spinning batch, it is necessary to have accurate laboratory data linear density of the fibers to be mixed, staple analysis of the individual the fake boys components (average staple length and unevenness in length), purity, linear the fake boys density of the strip, and other.
When designing the composition of the spinning batch linear density of the fibers must be such that in the cross section of the finished yarn has at least 50 filaments and the yarn in high-volume - at least 80-90 fibers.
1. In order to reduce the differences in the length of the fibers and to improve significantly the previous properties of the spinning mixture need to be mixed, bands from neighboring properties. For example, are allowed to mix tapes of different batches of properties 58 and 56. It is not allowed smesvnae strips of different batches, for example the fake boys 60 and 56 properties, soft to sharp.
2. In mixing bands should the fake boys be observed in the length of the fibers, which are composed of different lots. Unfortunate the fake boys selected bands instead of improving, could impair the spinning process and at the same time adversely affect the quality of the yarn.
If you need to mix wool with very uneven staple length may be added to improve chemical and fiber. In the selection of chemical fibers, however, they must meet the following condition - their average length is always greater than the average length of wool fibers, but not greater than the maximum allowable.
When selecting the staple diagram must be considered and the possibilities of downloading apparatus of spinning machines. If the fibers have a length greater than the ability of the retraction device, they can be retrieved even in the tape are obtained thickened.
The objective of the mixing of the strips in color to give them a new color that is different from that of the mixture bars. The mixing of color strips as possible, since predpredeneto marl strip was subjected to repeated doubling and drawing of which is ultimately obtained the fake boys a uniform mixture.
To design an appropriate melange mixed with a predetermined color, it is necessary to know the percentage of different colored fibers. Moreover, some of the fibers that will participate in the proposed mix will have to be with preset the fake boys colors. Other components can be dyed in the required mixture at the appropriate percentage. For this purpose, first prepare carved small melange blends. They mix different colored wool and chemical fiber and combine colors until obtain desired tszhyat of the mixture. Percentage of the individual components must be very precise. It is made by drawing different materials by precision balance the fake boys calculations. The smallest error in establishing the quantitative part of a color can alter the final color of the mixture. the fake boys This is especially true for those color components which are involved with a small percentage the fake boys in the mixture, and the components which are of a contrasting color.
It is desirable that certain mixtures t is given by the smallest possible number the fake boys of colors. For this purpose it is necessary to have a technologist sense of marl and know to color science the fake boys subtlety and harmony of colors.
The color of the final crafted mélange mixture the fake boys should be completely identical to that of the sample. When compared to the sample must be dried well and then compared. the fake boys Poorly dried sample has a color with a high gloss that changes color.
Another important requirement is for mixing, each component can be mixed for himself si.Tova means that each component must be turned a relevant tones (chemical fiber and wool fibers). This is because different types of fiber have different durability the fake boys dyed.
The mixing of bands to add lots and retrievable waste (edges) from the same batch. the fake boys For this purpose they need to be prepared in advance in the form ba bands that meet all quality requirements of decisions tape.
Another type of marl in worsted spinning applied rarely the fake boys is printed marl. It is done as follows.
