Problems solved by technology

In general, polyester fibers are known to be slightly inferior to polyamide fibers such as nylon 66 in terms of abrasion, but polyamide fibers are prone to photodegradation and yellowing, and are not suitable for harsh outdoor applications.

Embodiment 1

[0075] The base polymer was commercially available poly(trimethylene terephthalate) (component a)) to which 12 wt. % of thermoplastic elastomer polyurethane TPE was gravimetrically added to 80 wt. U (component b)), 6% by weight of a copolymer of polysiloxane of formula (1-1) and acrylate monomer (component c)), and 2% by weight of N,N'-di isopropylcarbodiimide (component d)).

[0076]

[0077] The polymer mixture is melted at 250°C to 270°C in the extruder, pressed into the spinning assembly by a gear pump, and then spun in a water bath at 68°C. Multiple stretches are performed under heat while heat setting and then the monofilament is wound.

[0078] Thus monofilaments obtained with a nominal diameter of 1.18 mm have the following textile values:

[0079] Diameter: 1.194mm

[0080] Linear density: 20000dtex

[0081] Free heat shrinkage 180°: 20.2%

[0082] Line strength: 35.4cN / tex

[0083] Nodule strength: 30.6cN / tex

[0084] Interlocking strength: 33.9cN / tex

Embodiment 2

[0087] The base polymer is a commercially available 4:1 blend of polytrimethylene terephthalate and polytrimethylene naphthalate (component a)) gravimetrically to 85% by weight before the extruder Add 10% by weight of thermoplastic elastomer styrene block copolymer (TPE-S) (component b)) in the raw material, 2.5% by weight of polysiloxane and acrylate monomer of structural formula such as (2-1) copolymer (component c)), and 2.5% by weight of N,N'-diisopropylcarbodiimide (component d)).

[0088]

[0089] The polymer mixture is melted at 250°C to 270°C in the extruder, pressed into the spinning assembly by a gear pump, and then spun in a water bath at 68°C. Multiple stretches are performed under heat while heat setting and then the monofilament is wound.

[0090] The performance qualities of the monofilaments obtained are listed in Table 1 below.

Embodiment 3

[0092] Repeat Example 2, the base polymer is commercially available polytrimethylene naphthalate raw material (component a)), thermoplastic elastomer polyurethane (TPE-U) (component b)), polysiloxane with hydroxyl (formula (3-1)) and hydroxyl-containing acrylate generate graft copolymer (component c) through condensation reaction), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide salt salt (component d)). The amount of each component is the same as in Examples.

[0093]

[0094]The performance qualities of the monofilaments obtained are listed in Table 1 below.

Abstract

The invention provides a wear-resistant fabric containing the monofilament, which belongs to the field of special textile fabrics, and the components of the monofilament include: a) selected from polytrimethylene terephthalate, polytrimethylene naphthalate , polytrimethylene terephthalate modified by dicarboxylic acid, polytrimethylene naphthalate modified by dicarboxylic acid or polyester raw material of their combination; b) thermoplastic elastomer block copolymer; c) organosilicon Modified polyacrylates; and d) carbodiimide stabilizers selected from DIC, EDC. The wear-resistant cloth containing the monofilament is coated with wear-resistant agent on its surface after dyeing. The beneficial effects are: the monofilament and the cloth have relatively excellent weather resistance, hydrolysis resistance, wear resistance and stain resistance, and can be applied to all industrial fields, especially in hot and humid environments that are expected to have high wear and high contaminated applications.

Description

technical field [0001] The invention belongs to the field of special textile fabrics, and in particular relates to a wear-resistant fabric. Background technique [0002] Generally speaking, wear-resistant fabrics are easier to think of canvas, but canvas is wear-resistant because canvas is much thicker than ordinary cloth. Compared with the same thickness, canvas may not be the best, because canvas is made of cotton fiber, and polyester (polyester) As long as the polyester fiber cloth of polyethylene terephthalate (PET) is less than half the thickness of the canvas, it can exceed the wear resistance of cotton canvas. Polyester fibers represented by polyester are used in a wide range of applications regardless of clothing and materials due to their excellent mechanical properties and handling properties. Therefore, many fibers and products that satisfy the required properties corresponding to various applications have been studied. develop. [0003] Abrasion resistance is o...
