Embodiment Construction

[0020] DTY composite yarn is generally made of a POY yarn which is false twisted and drawn and then plied with a FDY yarn. To improve the strength of DTY, the strength of FDY must be increased first, and then POY should be adjusted; the adjusted POY is twisted and drawn separately according to the original DTY composite yarn process, and the DTY yarn and FDY produced together are tested for strength and elongation. The strong waveform of this single DTY is basically the same as the undulation of the waveform after the strength of FDY is increased, that is to say, the breaking time of POY after twisting and drawing is almost the same as that of FDY after increasing the strength, only the two match intensity reaches its maximum value.

[0021] The technical solutions in the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only ...

Abstract

The invention discloses a spinning system and spinning method of a high-strength DTY composite yarn. The DTY composite yarn is formed in the manner that a POY and an FDY are stranded after twisting and drafting are carried out on the POY. A strength waveform graph of the twisted POY is matched with a strength waveform graph of the FDY. The strength of the POY and the strength of the FDY are increased to the maximum, meanwhile, the strength waveform graph of the POY and the strength waveform graph of the FDY are consistent in fluctuation, the strength of the elasticized DTY is greatly increased, the DTY strength can be increased to 3.6 from existing 3.2, and the increasing amplitude is 12.5 percent.

Description

technical field [0001] The application belongs to the spinning field, and in particular relates to a high-strength DTY composite yarn spinning system and a spinning method thereof. Background technique [0002] As we all know, due to the high intensity of military training, the requirements for clothing are relatively strict, especially in terms of strength, which is much higher than civilian silk. However, due to the strict requirements on dyeing and high color fastness of military clothing, most military products need to add masterbatches, and some masterbatches are added in a relatively large amount, which will cause a large loss of monofilament strength. The strength of the cloth surface has a greater influence. [0003] Polyester FDY+POY composite yarn belongs to a class of different shrinkage fibers that combine POY (pre-oriented yarn) and FDY (fully drawn yarn) with different shrinkage properties. But the intensity of existing composite yarn is difficult to reach th...
