Spinning equipment and spinning process for high-strength low-shrinkage composite fibers

Abstract

The invention provides spinning equipment and a spinning process for high-strength low-shrinkage composite fibers, and relates to the field of fiber spinning. The spinning equipment for the high-strength low-shrinkage composite fibers includes a machine box, wherein a material supply box is fixedly connected with the upper surface of the machine box, a material melting box is fixedly connected with the upper surface of the material supply box, and a spinning box is fixedly connected with the upper wall of the inner side of the machine box. According to the spinning equipment, cooling air is collecting through a hot air collection hood and taken away by an air blower, so that the cooling effect is improved; the high-temperature cooling air is blown into the material supply box through the air blower, so that heat loss is reduced; the hot air is blown into a heat setting box through the air blower, so that energy consumption needed by heating of a heat setting roller is reduced, and meanwhile the heat preservation effect is good through the heat setting cover and a second heat preservation layer; spinneret orifices are radially and annularly distributed in the spinneret plate in the mode that the spinneret orifices are gradually diffused outwards from a circle center, a ventilation channel is formed between every two sets of filaments, and the cooling air can penetrate through tows more easily for cooling.

Description

technical field [0001] The invention relates to the technical field of fiber spinning, in particular to spinning equipment and a spinning process for high-strength and low-shrinkage composite fibers. Background technique [0002] Composite fiber is a kind of multi-component fiber. It is a term for man-made fiber varieties. It is a physically modified fiber developed in the 1960s. Using composite fiber manufacturing technology can obtain dual-component fibers with the characteristics of two polymers. The composite fibers include side-by-side type, skin-core type, sea-island type and other composite fibers. The cross-section of the fiber has round and irregular shapes. The fiber has three-dimensional curl, high bulkiness and coverage, good conductivity, antistatic and resistance Combustibility, the composite fiber needs to be spun by a composite spinning machine with a special structure. The composite fiber is mainly used for wool, blankets, wool fabrics, thermal fleece filler...
