Problems solved by technology

[0003] The existing sewing thread products do not have a special sewing thread for down jackets. Generally, ordinary polyester staple fiber sewing thread or polyester filament sewing thread is used for sewing and interlining operations, which are common in the sewing process and interlining process. Pinhole velvet and the problem of velvet exposed by consumers during the wearing process have brought a lot of inconvenience to consumers

preparation example Construction

[0022] The invention provides a method for preparing sewing thread for down jackets, comprising the following steps: treating the gray yarn of the sewing thread with the above-mentioned compound auxiliary agent. Applying the above compound additives to the raw yarn of sewing thread can reduce the electrostatic adsorption effect between the sewing thread of down jacket and down, and can reduce the surface static electricity of sewing thread and down during sewing and wearing of down jacket, thereby avoiding pinholes in down jacket Lumpy problem.

[0023] Further, before the raw yarn of the sewing thread is treated with the compound auxiliary agent, the raw yarn of the sewing thread is dyed. This is a treatment of sewing thread preparation, that is, the process of adding after-treatment after dyeing. Specifically, the processing process of the compound auxiliary agent on the raw yarn of the sewing thread adopts the method of roller oiling or dyeing vat oiling. In the post-proc...

Embodiment 1

[0034] This embodiment provides a kind of composite auxiliary agent for down jacket sewing thread treatment, by weight, the composite auxiliary agent includes 0.5 parts of quaternary ammonium salt surfactant, 0.1 part of fatty amine polyoxyethylene ether and 5 parts of water .

[0035] Present embodiment also provides a kind of preparation method of down jacket sewing thread, it comprises the following steps:

[0036] High-strength polyester filaments are used as raw materials, and monofilament twisting, yarn doubling and re-twisting are carried out in sequence to obtain sewing thread gray yarn. Among them, the monofilament twisting process adopts the twist direction of S twist and the twist of 630 twists / meter, and the filament two-for-one twister of the model DX268V-180 / 225-450 can be used; the yarn winding adopts the model of DX231D-280 The doubling machine is carried out; the double twisting process adopts the twist direction of Z twist and the twist degree of 510 twists / ...

Embodiment 2

[0040]This embodiment provides a compound auxiliary agent for the treatment of down jacket sewing thread. In parts by weight, the compound auxiliary agent includes 10 parts of quaternary ammonium salt surfactant, 8 parts of fatty amine polyoxyethylene ether, and 80 parts of water , 8 parts of paraffin and 10 parts of simethicone.

[0041] Present embodiment also provides a kind of preparation method of down jacket sewing thread, it comprises the following steps:

[0042] Nylon filaments were used as raw materials, followed by monofilament twisting, yarn doubling and re-twisting to obtain sewing thread gray yarn, the specific process can refer to Example 1. After the obtained sewing thread gray yarn is dyed, the above-mentioned compound auxiliary agent is used to oil the dyeing vat under the condition of normal temperature.

[0043] This embodiment also provides a sewing thread for down jacket, which is prepared by the above-mentioned preparation method for sewing thread for d...

Abstract

The invention discloses a composite aid for treating a down jacket sewing thread, a down jacket sewing thread and a preparation method of the composite aid and relates to the technical field of sewingthread preparation. The composite aid for treating the down jacket sewing thread comprises the following components in parts by weight: 0.5-10 parts of a quaternary ammonium salt surfactant, 0.1-8 parts of polyoxyethylene ether and 5-80 parts of water. Due to adoption of the quaternary ammonium salt surfactant and the polyoxyethylene ether, a very good synergistic interaction is achieved, and thesewing thread is good in surface smoothing property in the down jacket sewing thread treatment process. After a sewing thread blank yarn is treated with the composite aid, the electrostatic adsorption effect of down jacket sewing threads and down feather can be reduced, so that the electrostatic adsorption effect of prepared down jacket sewing threads and down feather can be reduced, and the problem that the down feather leaks off from down jacket needle holes is avoided.

Description

technical field [0001] The invention relates to the technical field of sewing thread preparation, and in particular to a compound auxiliary agent for down jacket sewing thread treatment, down jacket sewing thread and a preparation method thereof. Background technique [0002] Sewing thread is the thread required for knitted and woven clothing products. According to the raw materials, it can be divided into three categories: natural fiber, synthetic fiber and mixed sewing thread. In the process of clothing preparation, sewing thread is not only the main auxiliary material of clothing, but also has a decorative effect. Sewing thread is a detail element that cannot be ignored in clothing production. The quality of sewing thread affects sewing effect, processing cost and appearance quality of finished product. [0003] The existing sewing thread products do not have a special sewing thread for down jackets. Generally, ordinary polyester staple fiber sewing thread or polyester f...
