Embodiment 1

[0017] Copolyester PET slices (melt-spun to obtain pre-oriented yarns, spinning speed is 2700m / min. Then the obtained pre-oriented yarns are processed through false twisting to obtain high-elastic false-twist modified polyester fibers, processing conditions: The temperature of the first hot box is 180°C, the temperature of the second hot box is normal temperature, and the elongation ratio is 1.7.

[0018] After testing, the 2-methyl-1,3 propanediol structural unit in the obtained fiber accounts for 20 mol% of the total glycol structural unit, and the melting point of the fiber is 220°C. After the fiber is made into a fabric, it is ironed with an iron at 225° C. for 10 seconds to fuse and produce an adhesive effect.

Embodiment 2

[0020] Copolyester PET chips were melt-spun to obtain unoriented filaments, and the spinning speed was 1500 m / min. Then the obtained unoriented filaments were stretched to obtain stretched fibers. The processing conditions were as follows: the temperature of the first hot roller was 90°C, the temperature of the second hot roller was 130°C, and the elongation ratio was 3.6.

[0021] After testing, the 2-methyl-1,3 propanediol structural unit in the obtained fiber accounts for 30 mol% of the total glycol structural unit, and the melting point of the fiber is 200°C. The fiber is made into a fabric, and it is fused with an iron at 210° C. for 10 seconds to produce an adhesive effect.

Embodiment 3

[0023] Copolyester PET chips were melt-spun to obtain unoriented filaments, and the spinning speed was 1500 m / min. Then the obtained unoriented filaments were stretched to obtain stretched fibers. The processing conditions were as follows: the temperature of the first hot roller was 90°C, the temperature of the second hot roller was 130°C, and the elongation ratio was 3.6.

[0024] After testing, the 2-methyl-1,3 propanediol structural unit in the obtained fiber accounts for 50 mol% of the total diol structural unit, and the fiber has no melting point. The fiber is made into a fabric, and it is fused with an iron at 200° C. for 10 seconds to produce an adhesive effect.

Abstract

The invention discloses easy-adhesion copolyester fiber. An acid component forming the copolyester fiber mainly has terephthalic acid structural units. In a dihydric alcohol component forming the copolyester fiber, the content of aliphatic diol structural units comprising side chain and carbon atom number under 6 is 20-90mol%. The fiber has no melting point or low melting point. When the fiber is prepared into fabric and when the fabric is heated by using a common iron or other heating devices, a partial fusion phenomenon occurs to the fabric, and an adhesion effect is provided. The fabric can be used in side locking of positions such as cuffs and trouser bottoms, and can be used in shaping of collars and the like, such that clothes can be provided with certain stiffness.

Description

technical field [0001] The present invention relates to a copolyester fiber and its fabric which are easy to stick. Background technique [0002] In the existing apparel industry, most of the joints of the cloth are stitched by threads. For the cuffs of trousers or jackets, the length of the legs or arms will also be different in consideration of individual differences, so the manufacturer only wraps the edge of the cloth at the bottom of the trousers when it leaves the factory, and there is no prying edge for stitching after folding. After purchasing, the consumer cuts off the edge of the trousers according to the actual leg length, and then folds the edge upside down and pries it. And the prying edge at this moment generally can only be stitched by hand with needle and thread, must have certain manual ability or ask people to process, there is certain inconvenience in use. [0003] Patent CN98237695.2 discloses a fabric with adhesive properties, the fabric is composed of...
