Embodiment
[0042] Embodiment: A production process of DTY wire includes the following steps:
[0043] S1, take a roll of island POY silk and feed it into the first heating box for heating;
[0044] S2, cooling the heated sea-island POY yarn, and false-twisting the cooled sea-island POY yarn to form the original yarn;
[0045] S3: Perform two rollers on the false-twisted raw yarn and feed it into the second heating box for heating to form a semi-finished yarn, which is cooled by a cooling plate;
[0046] S4: Feed the high-shrinkage FDY wire through the zero roller, so that the high-shrinkage FDY wire is wound around the semi-finished wire to form a preliminary composite wire;
[0047] S4: Air jet the preliminary composite yarn, so that the surface of the preliminary composite yarn forms a network point arranged at intervals, and output DTY composite yarn;
[0048] S5: Three rollers are applied to the DTY composite yarn, and then oiled to form a finished product.
[0049] Among them, the first heating...

The invention discloses a production process of DTY silk yarn and relates to the technical field of silk yarn production. The production process is characterized by comprising the following steps thatS1, POY pre-oriented yarn is treated by first rollers and then fed into a first heating box for heating, wherein the heating temperature is 193-198 DEG C; S2, the heated POY pre-oriented yarn is cooled, and the cooled POY pre-oriented yarn is subjected to false twisting to form raw silk, wherein the false twisting rate is 1.8; S3, the raw silk obtained after false twisting is treated by second rollers and fed into a second heating box for heating to form a semi-finished silk product, and the semi-finished silk product is cooled, wherein the heating temperature is 168-173 DEG C; S4, highly shrunk FDY is fed through zero rollers to be compounded with the semi-finished silk product to form preliminary composite silk; S4, air is sprayed onto the preliminary composite silk to form network points on the surface of the preliminary composite silk at intervals, and then the DTY composite silk is discharged; S5, the DTY composite silk is treated by third rollers to form a finished product. Theproduction process solves the problem of frequent fracture of the silk and has the advantage of improving the strength of the finished product.
Description
Technical field [0001] The invention relates to the technical field of silk thread production, in particular to a production process of DTY silk thread. Background technique [0002] DTY yarn is a kind of low-elastic polyester yarn, which is made of polyester chips as raw material, high-speed spinning polyester pre-oriented yarn, and then texturing. [0003] The Chinese patent with the authorized announcement number CN105064029B and the authorized announcement date on November 3, 2017 discloses a super-bright polyester DTY fiber and its preparation method. The polyester is measured, extruded, cooled, oiled, stretched, Heat setting and winding to prepare polyester fiber FDY yarn. [0004] The disadvantage of the prior art is that, during the production process of FDY yarn, false twisting and multi-pass stretching are required, which will cause the production of waste yarn due to the yarn breaking in the middle. There is a need to provide a method that can reduce the generation of in...
