Abstract
The invention discloses a spinneret which comprises a spinneret body and a spinneret cover; wherein, a plurality of capillary openings used for spinning are arranged on the spinneret cover which is prepared by adopting precious metal alloys; and the spinneret body is embedded at the top of the spinneret cover in a matchable manner. The spinneret cover is prepared by adopting the precious metal alloys containing gold and Pt, or containing gold, Pt and Rh. The spinneret body is prepared by adopting corrosion-resistant materials. By adopting the spinneret, the usage of the precious metal materials can be reduced on the premise of ensuring the quality of obtained viscose fiber products, thereby greatly reducing the production cost of the spinneret. The spinneret can be used in viscose industries for producing high-grade fibers.
Description
Technical field
The present invention relates to a kind of spinning head.
Background technology
Viscose is a kind of colory textile raw material, with its be the textiles of raw material have good moisture absorption, ventilative, soft, dangle and good characteristics such as antistatic.Along with the continuous lifting of modern people's health idea and fashion eye, consumers in general progressively improve the fashion-orientation of clothing fabric and the requirement of health care, and market improves constantly the demand of viscose, and is also more and more higher to the requirement of viscose quality.
The production process of viscose is that cellulose is generated alkali cellulose through after the basification, generates sodium cellulose xanthate with the CS2 reaction, makes viscose through dissolving, obtains viscose through spinning again under the effect of acid bath.In said process, spinning head is an important devices that forms viscose.Spinning head structure commonly used at present as shown in Figure 1.Head at sprayer body 1 offers a plurality of capilar bores 3 that are used to spray silk.Under pressure, be that fiber forms the cavity that medium infeeds sprayer body 1 with viscose, and extrude, thereby form fiber through capilar bore 3.Want to make the extruded velocity quickening and the hole is diminished, the pressure of the viscose that is applied to the spinning head head is increased.And for the ease of the formation of viscose, the sheet metal thickness that is used to make spinning head is generally 0.28～1.50mm.Common spinning head generally adopts tantalum material to make.
In order to improve the quality of viscose, produce high-grade fibers, a kind of spinning head that adopts noble metal alloys such as gold and platinum to make has appearred.The ratio of gold and platinum is Au: Pt=70 in this material: 30, and perhaps the ratio of gold, platinum and rhodium is Au: pt: Rh=49.5: 49.5: 1.This spinning head can prevent distortion under higher spinning pressure, and still can resist the high pressure that spinning duration produces.Adopt this class alloy material, not only can satisfy the required intensity of spinning head, and have fabulous decay resistance, be specially adapted to contain in the viscose in the technology of acid.Yet this spinning head that adopts noble metal alloys such as gold and platinum to make costs an arm and a leg, and its price is ten times of common tantalum spinneret, and the user is if use this spinning head, and the one-time investment height is difficult to bear.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of spinning head, and it can reduce the consumption of precious metal material, reduces the production cost of spinning head.
For solving the problems of the technologies described above, the technical solution of spinning head of the present invention is:
Comprise sprayer body and nozzle cap, sprayer body is embedded in the nozzle cap top; Nozzle cap is provided with a plurality of capilar bores that are used to spray silk; Described nozzle cap adopts noble metal alloy to make.
Described nozzle cap adopts the noble metal alloy that contains gold and platinum or contain gold, platinum and rhodium to make.
Described sprayer body adopts resistant material to make.
Described capilar bore is circular or special-shaped.
Described capilar bore is aligned to annular on nozzle cap or one-tenth group arranges.
Described sprayer body is circle, rectangle or ellipse.
The technique effect that the present invention can reach is: original integral type spinning head is improved to split type spinning head, only need nozzle cap is adopted noble metal alloy, and sprayer body uses common resistant material, can be under the prerequisite of guaranteeing gained fiber product quality, save the consumption of precious metal material, thereby significantly reduce the production cost of spinning head.
Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments:
Fig. 1 is the structural representation of existing spinning head;
Fig. 2 is the structural representation of spinning head of the present invention;
Fig. 3 is the vertical view of Fig. 2.
Among the figure, 1 sprayer body, 2 nozzle caps, 3 capilar bores.
The specific embodiment
As Fig. 2, spinning head shown in Figure 3, comprise sprayer body 1 and nozzle cap 2, nozzle cap 2 is provided with a plurality of capilar bores 3 that are used to spray silk.Nozzle cap 2 adopts noble metal alloy to make, and noble metal alloy contains gold and platinum, also can contain metal rhodium.Sprayer body is embedded in the nozzle cap top.
The present invention is improved to split type spinning head with original integral type spinning head, only need nozzle cap 2 is adopted noble metal alloy, and sprayer body 1 uses common resistant material, can save the consumption of noble metal alloy.
The employing diameter that the present invention produced is that the spinning head of 12mm is compared with original structure, and it is 0.6g that each spinning head needs the weight of noble metal alloy, and price only is more than three times of common tantalum spinneret; And the noble metal alloy weight that original structure needs is 3.1g.Therefore, adopt the present invention can significantly reduce the production cost of spinning head.
