Equipment

The invention relates to equipment or Finishing for synthetic, thermoplastic yarns

Some synthetic, thermoplastic yarns are made from polyamide, polyamide copolymers, polyesters, polyester ^ post-polymerizates or the like »produced»

Polyamide is a long-chain, synthetic, polymer Amide with repeating amide groups as an integral part of the main polymer chain and can be formed into threads, in. which the structural elements are aligned in the direction of the axis or are oriented. The polyamides include Uylon-66 (polymeric hexamethylene diammonium adipate), Uylon-6 (polymeric 6-aminocaeproic acid), nylon-610 (polyhexamethylene sebacamide), Nylon - *! ·, Nylon-7 »Nylon-11 and the like, as well as the fiber-forming polymers thereof.

Polyester is a long-chain, synthetic polymer which consists of at least 85 wt .- ^ of an ester of a dihydric alcohol and terephthalic acid <.

In the manufacture of textile materials from synthetic, thermoplastic yarn, various operations are carried out, which require a covering of the yarn with finishing or finishing agents, which would like slipperiness, antistatic and other properties, v; elche to be satisfactory Processing and handling are required. Depending on the end use, various Equipment for the same type of yarn may be required »

In a special case, when a polyamide yarn, on which standard equipment had been applied when Filling thread in the thread spool of a chair (quill of a v / eaving loom) was used, excellent lubricity and low and uniform coil take-off voltages became observed. Nevertheless, the yarn had poor binding and antistatic properties, including its handling weaving became difficult. In a second case, a different standard finish was used on the polyamide yarn with the result applied that the binding and antistatic properties were excellent, but this yarn showed high

Both of the emulsifying agents described above ("Span" and "Tween") consist of any mixtures of those used here The expression "any mixture" denotes a combination of components, the relative proportions of which are not critical are, Doh. the individual components can be used in combination in all proportions with respect to any other component without changing the end result, i.e. the appropriate emulsifying effect, which is achieved by combining the components, be present. With the equipment according to According to the invention, each of the emulsifying agents "Span" and "Tween" can be used either alone or in combination with one another come into use. A combination is preferred, since "Span" is lipophilic or oil-loving and "Tween" is hydrophilic or is water-loving, which also gives a better emulsion than using an emulsifier alone will.

It can be seen that any type of emulsifier capable of performing the same function, that is, appropriately emulsifying the lubricant with water, works as well as "chip." ^{or "Tween" or the combination thereof is} suitable for use in the equipment according to the invention

When synthetic, thermoplastic yarns are processed or treated, they are electrostatically charged. These charges, which are generated both by rubbing yarn or fabric against one another or by heating them to other bodies, give rise to different parts of the body which show themselves in different ways, depending on the oil and its use, "Electrostatically charged * G-arne and Tissues can not only repel one another but also attract one another and can contain dirt, dust, lint or the like. hold fast, weaving processes and other textile goods manufacturing operations are made more difficult by electrostatic charges on the yarn, which cause the threads to flare. To overcome these difficulties, it is necessary to use an antistatic agent in the equipment. In general, antistatic agents contain ionizable and / or hydrophilic groups which enable them to dissipate or dissipate static charges. These agents generally consist of long chain, surface active, nonionic or cationic agents, although anionic materials are somewhat effective Proven ^ 3Gat ionic agents, generally used as antistatic agents, include quaternary ammnuaih * l <% * n: 14 ",.
