Abstract
The present invention relates to the drafting part in textile equipment and is especially rubber roller with untreated surface for drawing frame and combing machine. The present invention aims at providing rubber roller with smooth, antistatic and winding resisting surface. The solution is to adopt the material including butadiene-acrylointrile rubber, sulfur, promoter, zinc oxide, coupling agent, antiaging agent, white carbon black, titanium white power, antistatic agent and auxiliary material. The present invention is suitable for various fiber of different texture.
Description
The present invention relates to the drafting unit in the textile equipment technical field, be specifically related to drawing frame, combing machine surface non-treatment cot.
In spinning process, yarn is to realize by the drafting system in the spinning equipment from the coarse to fine, rubber roll is the crux parts in the drafting system, because of its surface directly contacts with fibre bundle, so yarn qualities, the dried uniformity of bar, filoplume etc. are all had direct influence, so just require the rubber roll surface that fibre bundle is had enough grasping forces, require antistatic surface, smooth simultaneously, fibre bundle is difficult for twining on it.Be that the rubber roll that main material is made obtains general application in textile industry with acrylonitrile-butadiene rubber at present, this kind rubber roll grasping force is stronger, wear-resisting, oil resistance, moisture adsorption and releasing can be all better, therefore service life is longer, but for reaching rubber roll smooth surface and antistatic, make fibre bundle be difficult for the requirement of twining, be added with gelatine in the butyronitrile rubber roller, rubber roll produces a large amount of heat energy with the fibre bundle friction in high speed rotating, cause surface temperature to raise, gelatine melted and floats on the rubber roll surface when typical temperature reached 50～60 ℃, made the rubber roll surfaces of tacky twine fibre bundle.For addressing this problem, traditional solution is that rubber roll is carried out surface treatment, as method of chemical treatment, coating facture, photo-irradiation treatment method etc., rubber roll surface after the processing forms the duricrust of one deck dead smooth, therefore when reaching anti-winding purpose, brought new problem again: one, can produce slippery phenomenon between the rubber roll surface of aurora and the fibre bundle, easily cause the drawing-off of fiber irregularly and produce drafting wave is arranged, influence product quality; Two, the rubber roll surface is handled, promptly increased staff's workload, influence the healthy of staff, pollute work situation again; Three, the resultant yarn spinning suiting is relatively poor, and it is higher that the mass parameter discal patch is done the CV% index.For these reasons, at present to the development of surface non-treatment cot, become the focus of the common concern of textile industry.
The objective of the invention is provides a kind of smooth surface, antistatic property of keeping good for overcoming above-mentioned shortcoming, and anti-the winding can be improved cotton yarn dry mass, strong drawing frame, the combing machine surface non-treatment cot of spinning suiting.
