Description
Technical field
The present invention relates to a kind of method of warp sizing, especially the method for cotton ramie blended spinning yarn starching.
Background technology
Flax fibre has excellent economic value and social value as a kind of natural fabric and cotton fiber mixed yarn, the fibre length of flax fibre is longer than cotton fiber, ramee particularly, average fiber length reaches 60mm, its fineness ratio cotton fiber is thick, and intensity is big, and smooth surface does not have natural crimp, cohesive force between fiber and the fiber is poor, so its blended yarn filoplume is many and long, matter is hard and endure poor flexibility, elongation strain is little, evenness fault, details is many, the efficient when guaranteeing to weave on the cloth machine, technology during to sizing is transformed, upgrade, improve the importance of sizing before weaving.
Summary of the invention
The method that the purpose of this invention is to provide the starching of a kind of high efficiency cotton ramie blended spinning yarn.
For realizing that technical scheme provided by the present invention is:
The method of a kind of cotton ramie blended spinning yarn starching, it is characterized in that number such as 50s, 7664 of fabric total quantity of warps, suitably improve the viscosity of slurries during starching, stock tank viscosity 8.5-9.5s, increase mud jacking rod pressure, preceding mud jacking rod pressure 6.0-8.5KN, back mud jacking rod pressure 7.5-22KN, lining emphatically under the prerequisite that guarantees certain infiltration, make the filoplume on the yarn paste clothes as far as possible, need use wet leasing for obtaining this purpose, yarn filoplume before entering baking zone is in pastes the clothes state, strengthen gripping and the control ability of serous coat to yarn, keep its shape, unwinding tension 320-450N, yarn is lax as far as possible when entering stock tank, in sizing process, note simultaneously the unsuitable too fast 30-45m/min that is controlled at of the speed of a motor vehicle, the employing tandem sizing box, double-clip-double-nip reduces the coverage coefficient of sizing at stock tank, and the control soaking paste degree of depth is about 20cm, 95 ± 3 ℃ of the temperature of stock tank, improve the ability of soaking into of slurries, key is the control of soaking paste tension force, and tension force makes the starching infiltration difficulty of yarn too greatly, too low yarn produces kink, and it is more suitable to be controlled at about 300N.
Improve the viscosity of slurries during this method starching, lining emphatically under the prerequisite that guarantees certain infiltration, use wet leasing to make the filoplume on the yarn paste clothes as far as possible, strengthen gripping and the control ability of serous coat to yarn, adopt tandem sizing box, double-clip-double-nip to reduce the coverage coefficient of sizing at stock tank, improved the weaving efficiency of yarn on the cloth machine, sizing broken end phenomenon is less in the starching process, and the sizing junk reaches and must ask.
The specific embodiment
In the actual production, number such as 50s, 7664 of fabric total quantity of warps, suitably improve the viscosity of slurries during starching, stock tank viscosity 8.5-9.5s increases mud jacking rod pressure, preceding mud jacking rod pressure 6.0-8.5KN, back mud jacking rod pressure 7.5-22KN, lining emphatically under the prerequisite that guarantees certain infiltration makes the filoplume on the yarn paste clothes as far as possible, need use wet leasing for obtaining this purpose, yarn filoplume before entering baking zone is in pastes the clothes state, strengthen gripping and the control ability of serous coat, keep its shape, unwinding tension 320-450N yarn, yarn is lax as far as possible when entering stock tank, in sizing process, note simultaneously the unsuitable too fast 30-45m/min that is controlled at of the speed of a motor vehicle, the employing tandem sizing box, double-clip-double-nip reduces the coverage coefficient of sizing at stock tank, and the control soaking paste degree of depth is about 20cm, 95 ± 3 ℃ of the temperature of stock tank, improve the ability of soaking into of slurries, key is the control of soaking paste tension force, and tension force makes the starching infiltration difficulty of yarn too greatly, too low yarn produces kink, and it is more suitable to be controlled at about 300N.
Preparation method of the present invention is following steps:
1., unwinding tension 320-450N, when guaranteeing simultaneously that Sizing machines stops braking reliable, shorten the unwinding distance of warp thread on the warp beam, promptly through the forward arrangement of axle as far as possible;
2., suitably improve the viscosity of slurries during starching, stock tank viscosity 8.5-9.5s, increase mud jacking rod pressure, preceding mud jacking rod pressure 6.0-8.5KN, back mud jacking rod pressure 7.5-22KN, lining emphatically under the prerequisite that guarantees certain infiltration, make the filoplume on the yarn paste clothes as far as possible, use wet leasing, yarn filoplume before entering baking zone is in pastes the clothes state for reaching this purpose, strengthen gripping and the control ability of serous coat, keep its shape yarn;
3., 95 ℃-105 ℃ of drying tube temperatures, regain is at 8.5%-9.5%, drawing-off control DN1/DN21.0100/1.0020-1.0100/1.0010, the amount of waxing 0.1%-0.3%, do district tension force 2700 ± 500N, notice in sizing process that simultaneously the speed of a motor vehicle is unsuitable too fast, be controlled at 30-45m/min;
Below in conjunction with embodiment content of the present invention is described further:
Embodiment one
