preparation example Construction

[0024] The invention provides a method for preparing a chain element with a translucent effect, comprising the following steps:

[0025] After dehumidifying the polyethylene terephthalate chips, melt extrusion, cooling and stretching to obtain a transparent monofilament;

[0026] Dye the monofilament in the dyeing bath. Dyeing begins at 40-60°C, heats it up to 125-135°C and keeps it warm for 20-60 minutes. After cooling down, wash it with water to obtain dyed translucent monofilament;

[0027] The dye bath includes 0.001-6% owf of disperse dyes; 0.05-3 g / L of pH regulator and 0.001-3 g / L of leveling agent;

[0028] The dyed translucent monofilament is heated and pressed to obtain a continuous U-shaped element chain, which is combined to obtain a chain element with a translucent effect.

[0029] By using polyethylene terephthalate slices as raw materials, dyeing in a dyeing bath with a specific formula and under specific conditions, the chain teeth with a translucent effect ar...

Embodiment 1

[0043] Put the polyethylene terephthalate chips into the drying cylinder and dry continuously at 150°C for 7 hours;

[0044] After the above steps are thoroughly dried, stretched at 170°C, and then shaped at 230°C to obtain a transparent monofilament;

[0045] The above-mentioned transparent monofilament made is wound on the dyeing tool, and sent to the dyeing process for dyeing; the dye bath used in the dyeing includes disperse fluorescent yellow 0.05% (owf), disperse color blue 0.15% (owf), glacial acetic acid 0.2g / L, leveling agent 0.5g / L; bath ratio is 1:10. Add acetic acid, leveling agent, and dyes in the dyeing vat in turn, stir evenly, start dyeing at 40°C, heat up at 2°C / min, keep warm at 130°C for 20 minutes, wash with water after cooling down, and obtain dyed translucent monofilaments;

[0046] Wind the dyed translucent monofilament on the central rod, heat it to 160°C, and extrude it through two helical screws to form a continuous U-shaped plain chain; the two pla...

Embodiment 2

[0051] Put the polyethylene terephthalate chips into the drying cylinder and dry continuously at 150°C for 7 hours;

[0052] After the above steps are thoroughly dried, stretched at 170°C, and then shaped at 230°C to obtain a transparent monofilament;

[0053] The transparent monofilament obtained above is wound on the dyeing tool, and sent to the dyeing process for dyeing; the dyeing bath used in the dyeing includes disperse fluorescent yellow 0.23% (owf), disperse fluorescent red 0.19% (owf), glacial acetic acid 0.2g / L, leveling agent 1.0g / L; bath ratio is 1:12. Add acetic acid, leveling agent, and dyes in the dyeing vat in sequence, stir evenly, start dyeing at 60°C, heat up at 2°C / min, keep warm at 130°C for 30 minutes, wash with water after cooling down, and obtain dyed translucent monofilaments;

[0054] Wind the dyed translucent monofilament on the central rod, heat it to 160°C, and extrude it through two helical screws to form a continuous U-shaped plain chain; the t...

Abstract

The invention provides a preparation method for semitransparent scoops and a zipper. The preparation method comprises the following steps: dehumidifying a polyethylene terephthalate slice, and then successively carrying out melt extrusion, cooling and drawing and setting so as to obtain transparent monofilaments; dyeing the monofilaments in a dye bath, wherein dyeing of the monofilaments is started at 40-60 DEG C, then the monofilaments are heat to 125-135 DEG C and maintained at the temperature for 20-60 min, and the dye bath comprises a disperse dye (0.001-6% owf), a pH value regulator (0.05-3 g/L) and a leveling agent (0.001-3 g/L), and carrying out cooling and washing with water to obtain dyed semitransparent monofilaments; and subjecting the dyed semitransparent monofilaments to heating and compression molding and combining obtained continuous U-shaped blank chains so as to obtain the semitransparent scoops. The semitransparent scoops and cotton tapes are combined so as to obtainthe semitransparent zipper. The prepared zipper has unique visual sensation, so the grade of the zipper is enhanced; and the zipper also has good color fastness to washing, color fastness to perspiration and fastness to rubbing, and all the fastness is above level 4.

Description

technical field [0001] The invention belongs to the technical field of slide fasteners, and in particular relates to a fastener element and a slide fastener with a translucent effect. Background technique [0002] Clothing accessories are combined with current fashion trends, and zippers with special visual effects are becoming more and more popular among customers. Among them, color contrast zippers, as a recently popular effect, are highly sought after. [0003] However, the more common zippers on the market are all made of white zippers and then dyed. The cloth tape, chain teeth, and sutures of this zipper are all in one color, which gives people a sense of cheapness and does not meet the current standards. Popular personalized request needs. Contents of the invention [0004] In view of this, the purpose of the present invention is to provide a chain element and a slide fastener with a translucent effect. The slide fastener made of the chain element has a translucent ...
