Abstract

PURPOSE:To provide a water repellent capable of performing a durable water repelling processing without deteriorating the dyeability of a fiber product after the processing and useful as a treating agent before the dyeing process, by adding an anionic or nonionic surfactant to the water repellent in a specific wt.% based on an active component of the water repellent. CONSTITUTION:A water repellent for fibers mixed with at least one surfactant selected from anionic surfactants and nonionic surfactants in an amount of 0.05-50 times wt.% based on an active component of the water repellent is applied to a fiber product as a treating agent before a dyeing process. The surfactant adhered to the fiber improves the leveling of a dye in the next dyeing process and is removed by washing the fiber after the dyeing process. The water repellent component adhered to the fiber is further strongly adhered to the fiber by a heat treatment.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a water repellent for pre-dying treatment of fibers, and in detail,
The present invention relates to a water-repellent agent which is treated by a pad method or a spray method, and then is dyed uniformly by a dipping method, and which has excellent durability and water-resistance.

[Conventional technology]

Wanmizu processing is often performed using the pad method mainly during the finishing process after the dyeing process. Therefore, in order to improve the effect of the water repellent, it is necessary to use as much surfactant as possible to emulsify and disperse the active ingredients. Efforts are being made to use small amounts. However, even with this, the water resistance is inferior to that of the emulsifier, and the texture is also poor.

On the other hand, if dyeing is performed after water-repellent treatment, the surfactant in the water-repellent component will be removed during dyeing, resulting in a water-repellent finish with a good texture. It is extremely difficult to dye cloth uniformly.

[Problem to be solved by the invention]

In view of the above points, the present invention, as a water repellent agent for pre-dying treatment of fibers, can maintain the water-repellent effect by changing the composition of the water-repellent agent itself, while ensuring the level dyeing properties of the water-repellent agent. The purpose of this invention is to provide a new anti-water agent.

[Means to solve the problem]

The present invention provides a textile repellent containing at least one type of surfactant carried by an anionic surfactant or a nonionic surfactant in an amount of 0.05 to 50 times the weight of the active ingredient of the anti-water agent. It is a liquid medicine.

The amount of at least one type of surfactant selected from anionic surfactants and nonionic surfactants relative to the water-based component is particularly preferably in the range of 0.1 to 25 times the weight.

The water-repellent agent shown in the present invention includes a fluorine-based water-repellent agent, a silicone-based water-repellent agent, a paraffin water-repellent agent, and a zirconium-based water-repellent agent using the minimum amount of surfactant that can emulsify or disperse the water-repellent component. etc., and are not subject to any specific restrictions.

Examples of the anionic surfactant include carboxylic acid salts such as sodium lauric acid salt and N-lauroylsarcosine sodium salt, sulfonic acid salts such as α-olefin sulfonic acid sodium salt and dioctyl sulfosuccinate sodium salt, r Examples include acid ester salts such as sodium lauryl sulfate and sodium polyoxyethylene nonyl ether sulfate; phosphoric ester salts such as sodium polyoxyethylene octyl phosphate and potassium polyoxyethylene dodecyl ether phosphate.

Nonionic surfactants include polyalkylene glycol type such as polyoxyethylene octylphenyl ether and polyoxyethylene lauryl ether, polyhydric alcohol type 1 such as stearic acid monoglyceride, and fluorine type surfactants. , for example, nonionic surfactants such as perfluoroalkyl polyalkylene alcohols.

These surfactants can be produced by conventionally known techniques.

The fiber mentioned here can be applied to any shape such as thread, woven fabric, silk fabric, non-woven fabric, natural fiber, synthetic fiber, etc. regardless of the material.

[Effect]

The beneficial effects of the present invention can be considered as follows.

As an anti-water agent ingredient, for the active ingredient of an anti-water agent,
If 0.05 to 5.0 times the weight of a surfactant is blended to make an anti-water treatment agent, the anti-water agent component adsorbed to the fibers by drying or dry-curing after processing will stick and become surface active. The agent component becomes attached to the fiber, and in the next dyeing process by dipping, this attached surfactant improves the level dyeing properties of the dye, and only the surfactant is removed during dyeing and during washing after dyeing. By heat treatment, the fixed water-resistant component becomes even more firmly fixed to the fibers, resulting in water-resistant properties.

In this dyeing process, functional finishing agents containing components that can be absorbed into the fibers during dyeing, such as flame retardants, softeners, and antistatic agents, can be treated in the same bath as the dye.

〔Effect of the invention 〕

The present invention provides that when fibers are dyed with a water-repellent agent for fibers after drying or dry-curing using a dipping method such as a pad treatment or a spray method, dyeing can be carried out without uneven dyeing, and water-stirrability is achieved. is no inferior to other processing methods.
