Description

Washing-resistant non-melting drop flame-retardant curtain and its processing method

technical field

The invention relates to the technical field of fire protection, in particular to a washing-resistant and non-melting dripping flame-retardant curtain and a processing method thereof.

Background technique

With the rapid development of my country's economy and society, people's demand for cultural consumption continues to increase. In recent years, the number and scale of domestic theaters, singing and dancing entertainment venues have risen rapidly. There are a large number of combustible substances in theaters and places of singing and dancing entertainment, such as soft seats, sofas, soft package decoration materials, carpets, curtains, etc.

The "Code for Fire Protection Design of Building Interior Decoration" (GB 50222) requires that the combustion performance of stage curtains used in theaters should reach Class B1. From the perspective of materials, polyester, cotton and polyester-cotton blended fabrics account for a relatively large proportion of commercially available flame-retardant stage curtain products, and the combustion performance of products of different materials is quite different.

This application is mainly aimed at the research and development trend of washable flame-retardant curtains at home and abroad, and uses a variety of flame-retardant fiber blending methods to develop a flame-retardant curtain that is washable and has no melting droplets when burning, filling the domestic gap.

Contents of the invention

The purpose of the present invention is to provide a washing-resistant non-melting drop flame-retardant curtain and its processing method, which solves the problem that the existing theaters, singing and dancing entertainment venues are flammable and poor in flame retardancy, and have a great threat to human life and health.

In order to solve the above-mentioned technical problems, the present invention adopts the following technical solutions:

A washing-resistant flame-retardant curtain without melting drops, comprising 20-30 parts by weight of cotton fibers, 10-20 parts by weight of aramid fibers and 10-20 parts by weight of flame-retardant viscose fibers, the flame-retardant viscose fiber spinning solution 0.2-0.3 parts by weight of flame retardant are added to cotton fibers.

Preferably, the flame retardant includes one or more of Sandflam 5060, magnesium hydroxide, aluminum hydroxide, zinc hydroxide, ammonium dihydrogen phosphate, diamine hydrogen phosphate and triamine phosphate.

Preferably, the aramid fiber spinning solution further includes 0.1-0.2 parts by weight of a reinforcing agent, and the flame-retardant viscose spinning solution further includes 0.2-0.25 parts by weight of a reinforcing agent.

Preferably, the strengthening agent includes 0.5-1 weight part of dimethyl carbonate and 0.3-0.7 weight part of polyvinyl alcohol. The strengthening agent can greatly improve the wear resistance and toughness of the limit, and improve the washing resistance.

A method for processing a washing-resistant flame-retardant curtain without melting and dripping, comprising sequentially performing cotton blending, carding, drawing, roving, spun yarn, shaping, twisting, winding, shaping, warping, weft winding, and weaving, wherein , the cotton blending is respectively blending cotton and aramid fiber, cotton and flame-retardant viscose fiber.

As preferably, the relative humidity of the carding step is 50-70%, the relative humidity of the drawing step is 55-60%, the relative humidity of the roving step is 50-55%, and the relative humidity of the spun step is 45-50%. %. Maintaining a high relative humidity during spinning avoids static build-up.

As preferably, the length of the aramid fiber is 50-60mm and the fineness is 1.6-1.7dtex; the length of the flame-retardant viscose fiber is 35-40mm and the fineness is 1.6-1.7dtex.

Preferably, the roving twist is 2-3 twists/10cm, which should not be too high. For this reason, a smaller basis weight and a smaller roving twist coefficient are used to reduce uneven drafting of the spun yarn. The twist coefficient of the spun yarn should be appropriately increased, and it is generally more appropriate to take the twist coefficient of the design metric system as about 383. The spun yarn adopts a large rear draft gauge and a small rear draft multiple, and the draft cot adopts Rieter soft cot to improve the evenness of the finished yarn and ensure the quality of the spun yarn.

Preferably, in the setting step, the temperature is 80-90° C., and the setting time is 35-45 minutes, so as to avoid twisting of the aramid fiber.

Compared with the prior art, the beneficial effects of the present invention are at least one of the following:

Raw materials used in this application: cotton, aramid fiber, and viscose are all fibers without melting drops when burning, so the curtains made of them do not have melting drops.

Aramid and flame-retardant viscose blended fabric has soft hand feeling, good bulkiness, drapability, moisture absorption and air permeability, high strength and wear resistance, good cloth surface finish, color fastness and inability to melt when exposed to fire. Excellent properties such as dripping can meet the quality requirements of curtain decorative fabrics.

During the opening and cleaning process, the pressurizing roller needs a higher pressure to prevent the cotton lap from tearing, and the coiler and bell mouth and other strip guide devices should be kept smooth and smooth to reduce friction. The carding process adopts low speed, medium carding, small draft, and fast transfer technology to reduce damage to fibers and entanglement caused by easy static electricity, and reduce neps, impurities and short fibers.

The combustion performance and washability of five kinds of curtains obtained by embodiment 1-5 are tested, and the results are as follows:

The flame retardancy of the curtains in the above table is mainly due to their structural characteristics. The polymer molecular chain is mainly composed of aromatic chain regions containing heterocyclic rings. After the two kinds of fibers are mixed, the structure is stabilized due to resonance and the melting temperature is increased. , with improved strength and stiffness.

Due to the effect of adding Sandflam 5060 flame retardant to the viscose spinning solution, it decomposes at high temperature to produce a dehydrating agent, dehydrates and carbonizes the fibers, reduces the generation of flammable gases, and has better flame retardancy.

The two kinds of fibers in the fabric are mixed to increase the heat absorption of pyrolysis, thereby reducing the temperature and preventing the spread of combustion.

When the fibers in the fabric are burned, non-combustible gas or high-density steam will be released. The former slightly increases the dilution of oxygen and gaseous combustible products, and lowers the temperature, resulting in the termination of combustion. The latter can cover the combustible gas and suffocate the combustion.

Because the raw material cotton, aramid fibers and viscose used in the present application are all fibers without melting drops when burning, so the curtain made of it does not have melting drops.
