Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the production of a fabric having friction melting prevention ability and high fastness to prevent melting and tearing.

Synthesis 1111M! Polyester JvlI among lll products
J&F has high fiber strength, chemical stability, and dimensional stability.
It has advantages such as pleat retention and wrinkle resistance. Despite these advantages, it is less resistant to heat than natural fibers.

If you slide or fall while wearing the product in a gymnasium, the frictional heat generated by the impact friction with the floor may melt the fibers and tear the fabric.

Conventionally, as a method to prevent the fabric from tearing due to such friction, a silicone-based smoothing agent was soaked into the synthetic fiber fabric.
Pap. It is said that the treatment method using ing is effective. However, polyethylene terephthalate (PET)
When a fabric dyed in a deep color with a disperse dye is treated with a silicone resin, the color fastness inevitably decreases, and depending on the type of silicone resin and the concentration used, the decrease may be noticeable. This phenomenon is well known to those who are experts in textile processing, and as a result, there are many restrictions on the type of resin, the concentration used, the conditions for pea-setting after resin treatment, etc. In general, if the dyeing fastness (fastness to washing, fastness to sublimation) fF) is processed without any problems in terms of packaging, the frictional melting prevention effect will be small; In the case of designer clothing, troubles occur due to poor fastness, such as hot water contamination from ironing during manufacturing, and hot water contamination from washing after dye transfer during storage. As a measure for fastness, ordinary cationic dyeable polyester fiber (hereinafter referred to as CDP) is used.
It is called. ) and dyeing with cationic dyes that have good color fastness.2 However, since ordinary CDP has inferior fiber properties (melting point 9 strength, etc.) compared to PET, it is possible to dye it with a cationic dye that has good color fastness. However, it exhibits only the same level of melt-proofing properties as PET without melt-proofing, and is not suitable for applications that require melt-proofing properties.

The present invention was made in view of the current situation, and the present invention was made in consideration of the physical properties of the fibers.
It is called. ) This method is characterized by dyeing copolymerized polyester fibers with a cationic dye having good color fastness and then subjecting it to a friction-proofing treatment, and aims to eliminate the above-mentioned drawbacks.

In other words, Akira Kibai dyes a fabric made of cationically dyeable polyester fiber copolymerized with SIP in a range of 0.8 mol% to 1.8 mol% with a cationic dye, and then resin-processes it with a silicone resin. This is a method for producing a fabric having friction-proofing properties and high fastness.

The present invention will be explained in detail below.

The first feature of the present invention is that the SIP content is 0.8 mol% or more and 1.8 mol% or more.
The point is that cationic dyeable polyester fibers copolymerized in a range of mol % or less are used.

CDPf) The manufacturing method is well known and is not particularly limited, but in general, commercially available CDP and 17 are SI
It is a polyester fiber copolymerized with 2.0 to 3.0% P component, and is dyed at a dyeing temperature of 120°C or lower.

In the present invention, the number of moles of S-P added is [], 8 mol% or more''-i,
The reason for limiting the range to a mol % or less is as follows.

If the concentration is less than 0.8 mol % 1 u, the dyeability becomes extremely poor and a deep color cannot be obtained. In addition, at 1.8 mo/L'% or more, the fiber physical properties (
Fiber strength, melting point, etc.) make it unsuitable for friction and melt-proof processed products. In other words, the range in which deep dyeing using cationic dyes is 0.8 mol% or more and the decrease in fiber physical properties is relatively small is 1.8%.
Mo μ% or less.

The second feature of the present invention is that the CDP is dyed at high temperature with a cationic dye. SIP copolymerized polyester fibers are both cationically dyeable and fractionally dyeable. CDP
The reasons for dyeing with cationic dyes are (1) Cationic dyes generally have clear and deep hues.

(2) Cationic dyes have better wet and sublimation fastness than 9 disperse dyes, and less loss of fastness during resin processing.
) Cationic dyes cause less contamination of other fibers.

Examples include. - Ordinary IC
In the case of DP, it is dyed at a temperature of 120°C or less, but SIP copolymer polyester 120 referred to in the present invention
A sufficiently deep color cannot be obtained at a dyeing temperature below ℃. For this reason, high-temperature dyeing at 120° C. or higher is performed.

The high temperature dyeing referred to in the present invention is the normal CDP dyeing temperature of 12
It is dyeing at 0°C or higher, preferably normal P?
The ET dyeing temperature ranges from 150°C to 140°C.

The sixth feature of the present invention is that the CDP fiber fabric is processed with a silicone resin.

Friction-resistant products made by dyeing PET in deep colors with disperse dyes have good fiber properties, but there is a problem with color fastness, and as mentioned above, friction-proofing performance cannot be achieved if fastness is taken into account. .

5-Also, friction-resistant and melt-resistant processed products obtained by dyeing ordinary CJ) P in deep colors with cationic dyes have good fastness, but have problems with the fiber properties, making them unsuitable for applications that require friction-resistant and melt-resistant properties. do not have. In other words, in order to obtain a friction-resistant processed product with good fastness, which is the objective of the present invention, (1) the color fastness should be the same as that of ordinary CDP dyed with cationic dyes, and (2) the physical properties of the fiber should be Two points are required: it must be equivalent to normal PET.

The polyester fiber dyed at high temperature with the cationic dye referred to in the present invention can meet item (1) above, but item (2) is superior to ordinary CDP and can effectively counter PT2T. In terms of data, it is slightly inferior to PF2T.

In order to reinforce this point and eliminate any significant difference in practical terms, a finishing process using silicone resin is applied.

The silicone resin referred to in the present invention is 9 For example, hydrogen polysiloxane, methylhydrodiene polysiloxane, dimethyl polysiloxane or a co-condensate thereof, amino-modified silicone in which an aminoalkyl group is introduced into dimethyl silicone, or epoxy resin in dimethyl silicone. Examples include silicone-based softening and smoothing agents such as epoxy-modified silicones into which groups have been introduced. An example of a catalyst to be used in combination if necessary is tetrabutyl titanate.

Mention may be made of organometallic compounds such as tetrapropyl titanate, dibutyltin diacetate, digtyltine dilaurate, digtyltine maleate, tin octylate, cadmium stearate, lead naphthenate, zinc octylate, zirconium octate, and zirconium stearate. .

There are no particular limitations on the amount of silicone resin used and the amount of catalyst if necessary.

The polyester fiber fabric obtained by applying the method of the present invention has very good color fastness and is less likely to contaminate other fibers, making it ideal as a material for dark-colored clothing in which dark colors are combined with white or light colors. Therefore, there is no need to worry about fastness when applying friction-proofing processing, so there is no need to particularly limit the type and amount of processing agent used.

Resin processing can be done under the best conditions.

The present invention will be explained below with reference to examples, but the present invention is not limited thereto.
