Description
Technical Field
The invention relates to the technical field of textile production, in particular to a flame-retardant sewing thread.
Background
The flame-retardant sewing thread has low ignition point, good flame-retardant effect, difficult ignition, self-extinguishing from a fire source, waterproof function and permanent flame-retardant effect. The flame-retardant sewing thread is widely applied to sewing of fire-fighting and fireproof textiles, and can effectively improve the flame-retardant property of the textiles. With the widespread use of flame retardant sewing thread, many textiles in daily life are sewn with flame retardant sewing thread, such as garments, shoe uppers, luggage, and the like. The flame-retardant sewing thread is in close contact with the skin of a human body, so that the requirement on the comfort of the flame-retardant sewing thread is high. The existing flame-retardant sewing thread mainly comprises a pure polyester flame-retardant thread and an aramid flame-retardant sewing thread, but the two flame-retardant sewing threads are relatively poor in comfort and poor in air permeability and are not beneficial to long-time contact with human skin, so that the development of the flame-retardant sewing thread which is comfortable to wear and good in flame-retardant effect on human bodies is urgently needed.
Disclosure of Invention
The invention aims to overcome the problems in the prior art and provide a novel flame-retardant sewing thread which is suitable for being worn by a human body, has good comfort and excellent flame-retardant effect.
In order to achieve the technical purpose and achieve the technical effect, the invention is realized by the following technical scheme:
the flame-retardant sewing thread is prepared by blending aramid 1313, flame-retardant viscose and aramid 1414 fibers, and the yarn count is 35sIn the flame-retardant sewing thread, the weight percentage of aramid 1313 fiber is 20-95%, the weight percentage of flame-retardant viscose fiber is 10-70%, and the weight percentage of aramid 1414 fiber is 5-10%.
The aramid 1313 fiber, the flame-retardant viscose fiber and the aramid 1414 fiber are made into flame-retardant yarns through ring spinning, and then the flame-retardant sewing thread is made through a yarn steaming and shaping process. The ring spinning is a mechanical spinning method which is implemented by twisting spindle, ring and traveller and drafting by roller. The fiber strips after the slivers or the rough yarns are drafted are led in through the ring traveler in a rotating mode, the winding speed of the bobbin is higher than that of the traveler, and the fiber rough yarns are twisted to form spun yarns. The steel wire ring is driven by the bobbin to rotate around the steel collar through the yarn to twist, and meanwhile, the friction of the steel collar enables the rotating speed of the steel wire ring to be slightly less than that of the bobbin to be wound, so that the spinning speed is high. The yarn is woven by ring spinning, the shape of the yarn is a conical spiral line with fibers transferred inside and outside, so that the fibers are wound and connected inside and outside the yarn, and the yarn is compact in structure and high in strength.
According to the invention, the aramid fiber 1313 fiber, the flame-retardant viscose fiber and the aramid fiber 1414 are blended to prepare the flame-retardant sewing thread, and the content of the aramid fiber 1313 fiber and the flame-retardant viscose fiber is changed, so that the fireproof performance and high strength of the aramid fiber 1313 fiber can be well utilized, and the comfort performance of the flame-retardant viscose fiber can be utilized.
Further, the flame-retardant sewing thread is prepared by blending the following fibers in percentage by weight: 80-95% of aramid 1313 fiber, 10-20% of flame-retardant viscose fiber and 5-10% of aramid 1414 fiber.
Further, the flame-retardant sewing thread is prepared by blending the following fibers in percentage by weight: the weight percentage of the aramid fiber 1313 is 60-80%, the weight percentage of the flame-retardant viscose fiber is 20-40%, and the weight percentage of the aramid fiber 1414 is 5-10%.
Further, the flame-retardant sewing thread is prepared by blending the following fibers in percentage by weight: the weight percentage of the aramid fiber 1313 is 40-60%, the weight percentage of the flame-retardant viscose fiber is 40-60%, and the weight percentage of the aramid fiber 1414 is 5-10%.
Further, the flame-retardant sewing thread is prepared by blending the following fibers in percentage by weight: the weight percentage of the aramid fiber 1313 is 20-40%, the weight percentage of the flame-retardant viscose fiber is 60-80%, and the weight percentage of the aramid fiber 1414 is 5-10%.
Further, the weight percentage of the flame-retardant viscose fiber is not higher than 80%. In the flame-retardant sewing thread, the flame-retardant viscose fibers have the function of improving the comfort performance of the sewing thread.
The invention has the beneficial effects that:
the flame-retardant sewing thread fully utilizes the excellent thermal stability and flame-retardant property of the aramid 1313 fiber, the flame-retardant viscose fiber is comfortable and durable, the aramid 1414 fiber has good thermal stability, the advantages of various raw materials are reasonably balanced by adjusting the using amount of the raw materials, and further the flame-retardant property, the comfort property and the strength of the sewing thread are optimized.
