Problems solved by technology

Since polypropylene is a hydrocarbon polymer that does not contain any polar groups and chemically active genes, it is difficult to color the fibers. At present, the stock solution coloring method is generally used at home and abroad to color the fiber, but the color spectrum is limited, and it is difficult to meet the current people's requirements for diversified colors.
This limits the application of polypropylene in outdoor cloth

Embodiment Construction

[0009] 1. Ingredients

[0010] The raw material of the modified polypropylene air-textured yarn is 100 parts by weight of polypropylene; 15 parts by weight of lanthanum benzoate and 4 parts by weight of modified polystyrene containing polar groups. The above raw materials are combined at a temperature of 230-245°C. After mixing, melt granulation is performed.

[0011] 2. Spinning:

[0012] Spinning air-textured yarn on a laboratory simulated spinning machine, spinning at 240℃, 800m / min, and a post-drawing ratio of 3.8, to obtain modified polypropylene air-textured yarn. The above-mentioned air-conditioned yarn is conventionally woven into outdoor Shade cloth.

[0013] 3. Dyeing

[0014] Add the dye with a mass ratio of 2-4% to the modified polypropylene air-varying silk outdoor shade cloth and add it to the water after grinding, the bath ratio is 1:50, and then add 0.7g / l of conventional diffusing agent NNO and 0.4 parts by mass lacl 3 The auxiliary agent and JFC penetrant 2ml / L; add...

Abstract

The invention discloses a modified polypropylene air-jet texturing yarn outdoor havelock with high weather color fastness, which is mainly formed by spinning modified polypropylene air-jet texturing yarns. The modified polypropylene air-jet texturing yarn outdoor havelock is characterized in that: the modified polypropylene air-jet texturing yarn comprises the following raw materials of polypropylene, lanthanum benzoate and modified polystyrene containing polar groups in a mass ratio of 1:(1-1.5):(0.5-2.0); and after being blended at the temperature of between 230 and 245 DEG C, the raw materials are subjected to melting granulation, and the air-jet texturing yarns are spun to be weaved. The modified polypropylene air-jet texturing yarn outdoor Havelock has the advantages that: the defectthat polypropylene materials cannot be dyed is overcome effectively by the modification of the polypropylene materials; and by the processing, the dyeing problem is solved, and the stability of the color fastness is also ensured.

Description

Technical field [0001] The present invention mainly relates to a modified polypropylene air-variable fiber outdoor shade cloth with high weather fastness and its dyeing process, in particular to a modified polypropylene air-variable fiber textile formed by increasing the structure and properties of polypropylene The outdoor shading cloth is made into outdoor shading cloth, and according to the characteristics of the fiber, the corresponding dyeing agent is selected for dyeing to obtain an outdoor shading cloth with high weather fastness. Background technique [0002] Polypropylene (PP) began fiber-grade research and industrial production in the early 1960s. After rapid development in the 1990s, it has now become one of the main fibers in the textile industry. The various products produced are not only used in textiles and agriculture, but also widely used in medical and health fields. [0003] Polypropylene fiber has the characteristics of low density, good warmth retention and ab...
