Problems solved by technology

When the drying time of the acrylic fiber plus glue filter rod is too long, it is prone to quality problems such as cracking, shrinkage of the cut surface, and yellowing of the filter rod.
At present, this kind of problem has not been paid enough attention, and the research in this area is rarely reported.

preparation example Construction

[0013] Preparation of the spinneret: the leaf length and leaf width of the three-lobed spinneret holes on the spinneret are designed to be 0.51 mm in length and 0.16 mm in width.

[0014] Preparation of hydrophilic oil: mix Tween, Span emulsifier and antistatic agent to form oil, adjust the ratio of Tween and Span nonionic surfactant to adjust the hydrophilic and lipophilic (HLB) of the oil The value is between 11.5 and 13.5. Before spinning, according to the calculation of the real effective components of the oil, the oil is diluted to a concentration of 1.5%, and Tween 20 or Tween 80 is selected as the surface modifier, and its concentration is diluted to 2%.

Embodiment 1

[0016] In the one-step propylene fiber cigarette tow production line, the above-mentioned spinneret with 9100 holes and the hydrophilic oil agent with an HLB value of 13.2 are used, and the tow weight is sprayed with 5-10% of the weight of the tow after crimping, and the concentration is 2%. Surface modifier to produce fast-drying acrylic fiber tow with a linear density of 3.85ktex and a linear density of single filament of 4.23dtex. Compared with conventional tow of the same specification, the drying and setting time of the produced tow is It can be reduced by 22%; the drying time of the water-soluble acrylic fiber plus glue rod produced by this tow can be reduced by more than 30%. On the premise of ensuring the quality, the production capacity of the filter rod dryer can be increased by 31%, saving energy About 30%.

Embodiment 2

[0018] With the novel spinneret of 11000 holes and the hydrophilic oil agent that HLB value is 12.0, other is with embodiment 1, can produce tow linear density and be: 3.85ktex, monofilament linear density is: the quick-drying type acrylic oil of 3.50dtex Compared with conventional tow of the same specification, the drying and setting time of the produced tow can be reduced by 18%; the drying time of the water-soluble acrylic fiber plus glue stick produced by this tow can be reduced by 25%, On the premise of ensuring the quality, the production capacity of the filter rod dryer can be increased by 26%, and the energy can be saved by about 28%.

Abstract

A method for preparing quick-drying propylene fiber tow, using a new type of spinneret and a hydrophilic oil agent, through spinning, oiling, drawing, crimping, surface modification, drying and setting, laying, packaging, etc. process to obtain quick-drying type acrylic fiber tow. Use a new type of spinneret and hydrophilic oil agent, and spray 0.1-0.2% of the surface modifier of the total weight of the tow after crimping to obtain a quick-drying acrylic fiber tow. The drying and setting time of the tow can be reduced by more than 15%. The water-soluble acrylic fiber plus glue stick produced by the tow can reduce the drying time by 30% under the premise of ensuring the quality. The production capacity of the filter rod dryer It can be increased by 30%, and in the filter rod drying process, it can save more than 30% of energy consumption.

Description

technical field [0001] The invention relates to a method for preparing cigarette tow, in particular to a method for preparing quick-drying acrylic fiber tow. Background technique [0002] Cigarette filters play an important role in reducing coke and harm and improving the quality of cigarettes, and are an indispensable part of the cigarette production process. There are mainly two kinds of cigarette filter materials on the market: acetate fiber tow and acrylic fiber tow. Propylene tow needs to go through a drying and shaping process in its own production process; in the subsequent process of being processed into cigarette filters, it must also go through a drying process due to the addition of water latex. At present, the oil agent used for propylene fiber tow is usually composed of emulsifier, antistatic agent and grease (mineral oil or vegetable oil). Some manufacturers use water-in-oil lipophilic oil agent, so that the tow produced is dry by itself. The speed is slower ...
