Problems solved by technology

The hot press heats evenly, and the heating temperature, pressure, and time can be set according to the material of the fabric and the type of film. However, because the material and thickness of the fabric are different, excessive pressure and high temperature will damage the structure of the fabric. Influence, and then the appearance and function of the fabric are damaged, such as obvious pressing marks, etc., especially for the joint parts with corners and corners, the bonding folds are particularly obvious

Embodiment 1

[0025] The low melting point polyester with a melting point of 60°C and a copolymerization ratio of 30% is pre-crystallized and dried, then the raw material is melted at 120°C, and composite spinning is performed, followed by balance relaxation treatment, stretching and heat setting , to obtain a monofilament with a non-linear composite seamless hot-melt bonded S-shaped structure special for hot-pressed clothing.

[0026] The special hot-melt bonded S-shaped monofilament for non-linear composite seamless hot-pressed clothing obtained in this embodiment has a single composition cross-section structure, the elongation recovery rate of the monofilament is 20%, and the monofilament strength is 2.0cN / dtex. The elongation at break is 30%; the monofilament has a certain degree of elasticity, and it is easy to produce spring-like stretching deformation, and it also has a certain elongation recovery rate. It only needs to be heated to form a bond, and a composite seamless hot-pressed ga...

[0028] The polyester-polyamide elastomer with a melting point of 190°C and a copolymerization ratio of 10% is mixed with polyurethane according to a ratio of 1:1, and pre-crystallized and dried, and then the raw materials are melted at 220°C and processed. Composite spinning, followed by balance relaxation treatment, stretching and heat setting, to obtain a non-linear composite seamless heat-pressed garment special hot-melt bonded S-shaped monofilament.

[0029] The special hot-melt bonded S-shaped monofilament for non-linear composite seamless hot-pressed clothing obtained in this embodiment has a multi-component side-by-side cross-sectional structure, the elongation recovery rate of the monofilament is 200%, and the monofilament strength is 5.0 cN / dtex, the elongation at break is 140%; the monofilament has a certain elasticity, which is easy to produce spring-like stretching deformation, and also has a certain elongation recovery rate. It only needs to be heated to form a bo...

Embodiment 3

[0031] Mix polyolefin-based elastomers with a melting point of 130°C and an ethylene-propylene ratio of 50% and low-melting point polyamides with a copolymerization ratio of 40% at a ratio of 1:1, pre-crystallize and dry, and then place the raw materials in Melting at 200°C, composite spinning, and then balanced relaxation treatment, stretching and heat setting, to obtain a non-linear composite seamless heat-pressed garment special hot-melt bonded Z-shaped monofilament.

[0032] The special hot-melt bonded Z-shaped monofilament for non-linear composite seamless hot-pressed clothing obtained in this embodiment has an eccentric fiber cross-section structure, the elongation recovery rate of the monofilament is 100%, and the monofilament strength is 4.0cN / dtex. The elongation at break is 70%; the monofilament has a certain degree of elasticity, and it is easy to produce spring-like stretching deformation, and it also has a certain elongation recovery rate. It only needs to be heate...

Abstract

The invention discloses a hot melt bonded monofilament with non-linear shape and a preparation method thereof, and belongs to the technical field of chemical fiber manufacturing. Polymer raw materialsare subjected to pre-crystallization and drying treatment, and then melt and composite spinning are carried out to obtain the hot melt bonded monofilament with the non-linear shape special for composite seamless hot press clothing. According to the hot melt bonded monofilament special with the non-linear shape for the composite seamless hot press clothing, the monofilament has the characteristicsof high strength, excellent dimensional stability and difficulty in entanglement by means of unique combination of raw materials; when the monofilament is processed into the clothing, only heating treatment is required to form bonding, the composite seamless hot press clothing is obtained, and convenience is achieved; and the defects that a fabric structure is prone to being affected, the appearance and function of the fabric are damaged, and obvious pressing marks are generated are overcome.

Description

technical field [0001] The invention belongs to the technical field of chemical fiber manufacturing, and in particular relates to a non-linear hot-melt bonding monofilament and a preparation method thereof. Background technique [0002] The development of clothing materials has gone through several stages such as natural fibers, chemical fibers and high-performance fibers. Since the 1960s, with the continuous advancement of synthetic fiber technology, various new high-performance fibers have emerged one after another, and the performance of fabrics has been improved and improved. This has also become the primary driving force for the continuous development and progress of sportswear fabrics. At present, the research and development of clothing materials has gone deep into the microscopic level of fibers. Depending on the development of science and technology, new materials such as nanometers are also being continuously researched and developed. These developments and progres...
