Abstract
The invention relates to the technical field of cloth (yarns and lines) guide roller production in textile chemical fiber, spinning and dyeing machinery, and provides a production method for a light high-strength and energy-saving cloth guide roller. The method includes the steps of mixing polyether polyol, a foam stabilizer, a polyurethane catalyst, a foaming agent and isocyanate, and filling the mixture into a sealed thin shell barrel-type roller body at a 0-40 DEG C temperature environment to form the cloth guide roller through foaming. A roller body manufactured by the method is light in weight, good in high-temperature resistance, capable of effectively improving temperature uniformity of a roller wall, and favorable for improving shaping quality of the yarns, reducing color difference and improving dyeing quality, and the roller body is 1/4-1/2 of a traditional roller piece in weight.
Description
Technical field
The present invention relates to textile technology field, particularly the selvage guide in chemical fibre, spinning, the dyeing machine (yarn, line) roller production technical field.
Background technology
In chemical fibre, spinning or dyeing machine, need to adopt various roller spare draw fibers, yarn or cloth, for guaranteeing the rigidity of roller, use thick template material coiling and molding in designing and producing, after multiple tracks processing, could become certified products.There is the own wt weight in this roll body, manufacturing cost is high, consumptive material is many.A series of defectives such as installation back power draw height, power consumption are big.
Summary of the invention
The object of the invention is to propose a kind of, production method of using power consumption few high-strength light energy-conservation fabric guide roll low from heavy and light, cost.
Hard polyurethane foams is put in the present invention's filling in the shell tubular roll body of sealing, through foaming.
The present invention supports shell tubular roll body by hard polyurethane foams, can reduce the material thickness of using of roll body greatly, overall weight is light, be 1/4～1/2 of conventional roll part weight, and housing is indeformable, do not shell, have fabulous heat-resisting quantity, cost of manufacture descends 30%～50%, the advantage that have significant energy savings, cuts down the consumption of energy.
In addition, because the present invention adopts hard polyurethane foams, can effectively improve the temperature homogeneity of roller wall, be beneficial to and improve yarn typing quality, reduce aberration, improve printing quality.
In order to improve the resistance to pressure of product, the density of described hard polyurethane foams is 50～200kg/m
3
The concrete production technology of the present invention is: after polyether glycol, foam stabilizer, catalysts for polyurethanes, foaming agent and isocyanates are mixed with the mass ratio of 1 ︰, 0.02～0.05 ︰, 0.02～0.05 ︰, 0.1～0.5 ︰ 1～1.5, under 0～40 ℃ temperature environment, inject in the shell tubular roll body of sealing, through foaming.
The specific embodiment
1, the preparation of expanding foam solution: take by weighing 100kg polyether glycol, 2～5kg foam stabilizer, 2～5kg catalysts for polyurethanes, 10～50kg foaming agent and 100～155kg isocyanates respectively, mix in the mixer inner support and mix, stand-by.
2, foam process: expanding foam solution is injected in the selvage guide roll body, place under 0～40 ℃ the temperature environment and foam.
3, detect:
Take out foaming body from the product of foaming, after testing, its density is 50～200kg/m
3Weight is 1/4～1/2 of conventional roll part weight.
Claims (3)
1. the production method of the energy-conservation fabric guide roll of high-strength light is characterized in that hard polyurethane foams is put in filling in the shell tubular roll body of sealing, through foaming.
2. according to the production method of the energy-conservation fabric guide roll of the described high-strength light of claim 1, the density that it is characterized in that described hard polyurethane foams is 50～200kg/m
3
3. according to the production method of the energy-conservation fabric guide roll of the described high-strength light of claim 2, it is characterized in that injecting in the shell tubular roll body of sealing under 0～40 ℃ temperature environment after the mass ratio mixing with 1 ︰, 0.02～0.05 ︰, 0.02～0.05 ︰, 0.1～0.5 ︰ 1～1.5 of polyether glycol, foam stabilizer, catalysts for polyurethanes, foaming agent and isocyanates.
