Milling formulations detection fulling agent component tests
Fulling agent formulation components is composed mainly by the surface active agents, softeners, antifoaming agents and other chemical reagents.Micro-spectrum technology based on the analysis of the test course mastery milling agent for textile dyeing process, specialized milling formulations detection fulling agent component tests.
, Shrink it agent Overview
Fulling agent formulated products are mainly used in woolen fabric.Wool fulling (including senior animal fibers) mainly by the directional friction effect, the injury is a condensing process in the improper actions of friction, thus reducing friction coefficient of static friction is essential, according to the traditional sequence, the various types of surface-activeinitially to a conventional condensing agent reduces the order of the coefficient of static friction properties, it aids given bits.Fulling agents, temperature, and pressure, give full play to the wool fulling performance, so that the fabric is tightly, feel rich soft fluff process table.
Second, fulling the purpose and the basic principle
1 Purpose
(1) close texture, increased thickness and strength improve, flexible, warm and enhancements;
(2) exposed on the surface covered by the layer of fluff to the tissue and improving the appearance of fabric;
(3) up to the required length, width and unit area weight;
(4) conceal it match some weaving defect, and not clearly exposed in the face it.
2, fulling principle
Full use of the fulling of the wool, and to achieve the fulling the purpose.Wool felting performance in the following three aspects:
Directional friction effect that (1) wool fiber cuticle layer the DFE (Directional Frictional Effect);, and the DFE = (u2-u1) / (u2 + u1);
Where: u1-from the hair root to the the Tippy direction running friction coefficient;
u2-from Tippy run coefficient of friction direction of the hair roots; wool directional friction effect and the greater the stronger the fulling of the wool fibers.
(2) wool fibers excellent elasticity
Acute elastic recovery of the wool of the wool fibers to produce a certain degree of retraction, between the wool fibers relative motion occurs many times, and will procure wool interleaving and tangles favor fulling.
(3) natural crimp properties of wool fibers
The wool straight becomes curly process, the inevitable with similar hair entwined, At the same time the the wool sport is an irregular peristalsis.Wool curled more and more fulling.
To sum up, shrink it, you can choose a suitable condensing it formulated products, wetting the wool fibers, expansion, the scales tip Zhang farther apart.At this time, by the fulling machine applied external force, forcing the the wool fibers mobile, interspersed with each other to form a mesh, the free state and the tip was covered on the surface of the fabric so that the surface to produce fluff, to achieve condensing it's purpose.
Third, the condensing agent formulation main component selection
By surfactant and the level of development, is not a single component additives can be enriched in all the features required of the condensing agent and therefore must engage aid compounded.Typically, fulling order of the reduced static friction coefficient of the various types of surface active agents in the formulations are as follows: cationic> polyol ester type non-ionic> anionic> polyethylene glycol type non-ionic mineral oil (from left to right the ability to reduce the static friction is reduced).
Conventional condensing agent LS 209, the anion of the sodium alkylbenzene sulfonate (ABS), Lamepon (alkaline state) are; R5, 824 benzene is a polyethylene glycol type non-ionic, order row Next, so its shrink resistance merely low-grade level, switch cationic or polyol quinoid nonionic shrink effect will be greatly improved.With the industrial development of the surfactant, various additives can elect a certain kind, and it reduced static friction capacity far stronger than listed.The alkaline earth metal fatty acid soaps, polyethers and poly (ethylene oxide), mixed non-ionic, no less than the cations and polyol ester type differential, and this is also the importance of the system condensing it formulations.
