CS241329B1 - Lubricant for glass fibres treatment - Google Patents

Abstract

The solution describes the use of esteramine of formula CQOH COOCH2 CH2N (CH2CH2OH) z as a glass fiber lubricant. Using it can reduce tension when rubbing glass fibers, which allows its use for the textile processing industry glass fibers.

Description

(54) Glass fiber treatment lubricant

1

The solution describes the use of an esteramine of the formula

CQOH

C00CH = CH ₂ N (CH ₂ CH _{2 OH)}

as a glass fiber treatment lubricant. By using it, it is possible to reduce the friction stress of the glass fibers, which makes it suitable for the textile fiber processing industry.

The present invention relates to a lubricant suitable for use as a glass lubricant; viáklen. [0004] To reconstruct the cellar trainers, they have found a wide range of roast greases, Xtor, which have improved their ability to produce the desired fiber, such as fabric, wool, mats, and the like. Various mineral, natural or synthetic oils and waxes or oxyalkyloalkylated fatty acids, alcohols and the like are used for this purpose. (Czechoslovak author's certificate No. 198 315). To a lesser extent, mainly from economic reasons, various silicone compounds are used (cf. No. 185 291, 185 293).

The major disadvantage of most of these compositions is that their non-polar character impairs the other application properties of the fibers, especially the wettability, especially when using different oils and waxes. Amphipathic compounds appear to be similar due to the orientation on the surface of the glass fibers.

These problems are largely eliminated when using a lubricant according to heat. SUMMARY OF THE INVENTION is that an etheramine of the formula -30 '

COOH _ '’

CO O CH = CH ₂ N (CH _of CH _{of OH)}

This new use of said esteramine is based on its ability to impart stress on friction of fibers with different-textile conductors and devices. This particular property of esteramine extending its use, even in the glass fiber textile processing industry, could not be predicted either from its structure or from its physical properties.

When using a lubricant according to the invention, the surface treatment of the glass fibers due to the orientation on their surface gives the fibers a polar character, which improves their wettability with polar plastics, especially epoxy resins in the production of fiberglass, as opposed to conventional lubricants. ; ~ ’

The invention is further illustrated by way of example.

Example. The 0.5% by weight of the various lubricants in the table were used to treat the glass fibers and all were evaluated under different conditions.
