Abstract
The invention discloses a purpose of a water soluble MDI-TMP (Diphenyl-Methane-Diisocyanate-Trimethylol Propane) type polyurethane prepolymer as a dyeing and finishing agent in textiles. Because the toxicity of the water soluble MDI-TMP type polyurethane prepolymer is low, less harm to human body is obtained; meanwhile, the anti-crease performance of the fabric can be improved.
Description
Technical field
The invention belongs to field of textiles, relate in particular to the application of dyeing and finishing agent in the weaving.
Background technology
Polyurethane is because therefore its paint film good mechanical property, tough and tensile, wear-resisting, plentiful, bright can have purposes widely, especially in synthetic fiber and textile finshing agent field in low-temperature setting.Soluble polyurethane is medium with water, and safety is nonflammable, has kept the premium properties of conventional solvent type polyurethane, can give the good pliability of fabric, richness, washable, wear-resisting, performance such as resilience is good, smooth simultaneously.But traditional soluble polyurethane all is to adopt TDI (toluene di-isocyanate(TDI)) and TMP (trimethylolpropane) to synthesize to obtain, but TDI is very big to human harm, and the free TDI content of the TDI-TMP type bridging agent of domestic production at present is many 2 ~ 5%.
Summary of the invention
Goal of the invention: the defective to above-mentioned existence the invention provides a kind of application of water-soluble MDI-TMP type polyurethane performed polymer in weaving that utilizes environment-friendly type.
Technical scheme: for realizing the foregoing invention purpose, the present invention adopts following technical scheme: a kind of purposes of water-soluble MDI-TMP type polyurethane performed polymer, in weaving, use as dyeing and finishing auxiliaries.
Specifically, the purposes of said water-soluble MDI-TMP type polyurethane performed polymer realizes through following steps: a, water-soluble MDI-TMP type polyurethane performed polymer joined in the pure water be uniformly dispersed, obtain dyeing and finishing liquid; B, cloth immersed dyeing and finishing liquid after, again through rolling, and prebake; C, the roasting baking of process then; D, at last again through soaping and washing.
To the improvement of technique scheme, the prebake temperature is 70 ~ 80 ℃ among the said step b, and the time is 2 ~ 3min.
Further technique scheme is improved, the temperature of roasting baking is 100 ~ 130 ℃ among the said step c, and the time is 2 ~ 4min.
Beneficial effect: compared with prior art, the present invention has the following advantages: because the water-soluble MDI-TMP type polyurethane performed polymer that adopts environment-friendly type is as the dyeing and finishing agent, the more environmental protection of the fabric of acquisition can not damage human body; The wrinkle resistance and the elastic handfeel of fabric have been improved simultaneously.
The specific embodiment
Below in conjunction with embodiment, technical scheme of the present invention is elaborated, but protection scope of the present invention is not limited to said embodiment.
Embodiment 1
Water-soluble MDI-TMP type polyurethane performed polymer is mixed with the weight ratio of 1:1 with pure water, obtain dyeing and finishing liquid, then cotton is immersed wherein; Under 80 ℃, prebake 2min is then under 120 ℃ temperature after the process rolling; Baking 3min soaps at last and washes.
On YG (B)-541D type elastic apparatus, detect, the crease-resistant recovery angle of cloth after dyeing and finishing is handled 89.3 ° before handle are brought up to 125.2 °; And the poisonous favourable TDI content of monomer in the water-soluble MDI-TMP type polyurethane performed polymer is less than 0.5%.
Claims (4)
1. the purposes of a water-soluble MDI-TMP type polyurethane performed polymer is used as the dyeing and finishing agent in weaving.
2. the purposes of water-soluble MDI-TMP type polyurethane performed polymer according to claim 1 is characterized in that realizing through following steps: a, water-soluble MDI-TMP type polyurethane performed polymer joined to be uniformly dispersed in the pure water obtain dyeing and finishing liquid; B, cloth immersed dyeing and finishing liquid after, again through rolling, and prebake; C, the roasting baking of process then; D, at last again through soaping and washing.
3. the purposes of water-soluble MDI-TMP type polyurethane performed polymer according to claim 2 is characterized in that: the prebake temperature is 70 ~ 80 ℃ among the said step b, and the time is 2 ~ 3min.
