Problems solved by technology

CVC flame-retardant fabrics that can meet the requirements of actual flame-retardant applications are basically CVC flame-retardant fabrics, that is, blended fabrics with a higher cotton component mass percentage than polyester components. Since the flame retardant is achieved through post-finishing, the hand feeling is not good, and the washing resistance is poor. The poor washability mainly means that the added flame retardant is easy to lose during washing and loses the flame retardant effect); while the flame retardant polyester-cotton fabric with a higher polyester content than cotton content has not yet been realized. This type of polyester-cotton fabric reflects the good retention

preparation example Construction

[0049] 1. Preparation of polyester-cotton blended fabric

[0050] Take the polyester-cotton blended fabric used as raw material for preparing flame-retardant copolyester chips with a phosphorus content of 7000ppm as an example:

[0051] Put the flame-retardant copolyester chips into a vacuum drying chamber and dry at 120°C for 12-14 hours to make the water content lower than 0.02wt%. Melt-spinning is carried out according to the conventional polyester fiber melt-spinning method to obtain flame-retardant polyester Fiber; Cotton fiber is carried out flame retardant treatment by any prior art method, such as can carry out flame retardant finishing according to routine Proban (Proban) method, namely at room temperature by padding by four hydroxymethyl phosphorus chloride and amide Flame-retardant finishing liquid composed of low-molecular pre-shrinkage body → pre-drying on heat setting machine (100-120°C) → ammonia fumigation → oxidation washing → drying (130-140°C) → pre-shrinkin...

Embodiment 1

[0055] Under normal temperature, 950 grams of phosphorus-containing cyanuric acid epoxy acrylate (structural formula B is 500 grams, structural formula C is 450 grams) and 50 grams of N, N-methylenebisacrylamide are mixed with mass percent concentration with ethanol 30% glue, mixed evenly, placed in the glue tank of the padding machine, the polyester-cotton blended fabric F8500 (50 / 50) passed through the glue in the glue tank, and passed through the padding machine under the roll pressure of 0.15MPa. Second dipping and second rolling, and then drying in a blast oven at 100°C to obtain the dipped polyester-cotton blended fabric;

[0056] Under normal temperature and nitrogen protection, the above-mentioned dipped polyester-cotton blended fabric was irradiated in a 1MeV electron beam equipment, and the irradiation dose was 150KGy. The fabric was soaped and rinsed, then dried and weighed, and the mass percentage of the fabric increased by 24%. , to obtain a washable flame-retarda...

Embodiment 2

[0058] With water, 800 grams of vinyl phosphoric acid and 200 grams of N-methylolacrylamide are prepared into a glue solution with a mass percentage concentration of 45%, mix well, place in the glue solution tank of the padding machine, and put the polyester-cotton blended fabric F6500 (92 / 8) pass through the glue in the glue tank, under the roll pressure of 0.3MPa, go through the second dipping and second rolling of the padding machine, and then dry in a blast oven at 120°C to obtain the dipped polyester-cotton blended fabric;

[0059] Under normal temperature and nitrogen protection, the above-mentioned dipped polyester-cotton blended fabric was irradiated with an electron beam with an irradiation dose of 100KGy, then soaped, rinsed with water, weighed after drying, and the fabric increased by 16% by mass to obtain washable Flame-retardant polyester-cotton blended fabric 2; Others are the same as in Example 1, omitted.

Abstract

The invention discloses a washing-resistant flame-retardant polyester cotton blended fabric and a preparation method thereof. The fabric contains flame-retardant terylene fiber and flame-retardant cotton fiber, and is characterized in that the outer surface of the formed fiber of the polyester cotton blended fabric is soaked by glue liquid containing fire retardants and crosslinking agents; then, the flame-retardant terylene fiber and flame-retardant cotton fiber with the outer surface soaked with the fire retardants and the crosslinking agents are subjected to grafting reaction to form a surface layer material; then, soaping, rinsing and drying are performed; the washing-resistant flame-retardant polyester cotton blended fabric is obtained. The washing-resistant flame-retardant polyester cotton blended fabric has the characteristics of flame-retardant performance, water washing resistance and the like; the production process is simple; the efficiency is high; wide application prospects are realized in the fields of decoration materials, individual protection garments and the like for industrial and traffic buildings with fireproof requirements in electric power, petroleum and the like; the practicability is high.

Description

technical field [0001] The invention belongs to the flame-retardant technical field of polyester fiber and cotton fiber blended fabrics, and relates to a washable flame-retardant polyester-cotton blended fabric and a preparation method thereof. The washable flame-retardant polyester-cotton blended fabric of the invention is suitable for fire prevention in all walks of life field. Background technique [0002] Polyester-cotton blended fabric is favored by consumers because of its hygroscopicity and breathability of pure cotton fabric and high strength of polyester fabric. Its dry and wet fabrics have good elasticity and abrasion resistance, stable size and low shrinkage. , has the characteristics of being crisp, not easy to wrinkle, easy to wash, smooth, quick-drying and durable, and occupies an important position in my country's textile fabric market. Polyester-cotton blended fabrics are not flame-retardant, and the flammability of polyester / cotton fabrics exceeds that of pu...
