Embodiment

[0042] Embodiment: a kind of production technology of DTY silk thread, comprises the steps:

[0043] S1, carry out a roller pull on the island POY yarn, and feed it into the first hot box for heating;

[0044] S2, cooling the heated sea-island POY yarn, false twisting the cooled sea-island POY yarn to form a raw yarn;

[0045] S3, carry out two roller pulls on the raw yarn after false twisting, and feed it into the second hot box for heating to form semi-finished yarn, and cool it through the cooling plate;

[0046] S4, feeding the high-shrinkage FDY yarn through the zero roller, so that the high-shrinkage FDY yarn is wound on the outside of the semi-finished yarn to form a preliminary composite yarn;

[0047] S4, spraying air on the preliminary composite yarn, so that network points arranged at intervals are formed on the surface of the preliminary composite yarn, and the DTY composite yarn is output;

[0048] In S5, the DTY composite yarn is pulled by three rollers, and th...

Abstract

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. It is made of polyester chips, which are spun at high speed into pre-oriented polyester yarns, and then processed by adding elastic. [0003] The Chinese patent with the authorized announcement number CN105064029B and the authorized announcement date of November 03, 2017 discloses a super-bright polyester DTY fiber and its preparation method. The polyester is measured, extruded, cooled, oiled, stretched, Heat setting and winding, made polyester fiber FDY filament. [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 may result in the production of waste yarn due to the breakage of the yarn in the middle. It is desirable to provide a method capa...
