Description

 The invention relates to technology for knitwear production.

 A known method of obtaining a warp knitted fabric on.with. USSR 1520165, IPC D 04 В 21/02, 1989, characterized by the production of a knitted warp knitted fabric with 7-needle weaving from a nylon complex thread 6, 7 tex, which is washed, dried, dyed, and heat-fixed.

 The material obtained by this method in appearance meets consumer requirements.

 Requirements for upholstery materials, such as greater strength, wear resistance and practicality, led to the development of the invention.

 This object is achieved in that in the method for producing upholstery material, the cap is trimmed, including the production of a warp knitted fabric with weaving a trico-charm from a 6.7 tex nylon complex thread subjected to washing, drying, dyeing, heat setting, according to the invention, the weaving is carried out with parallel laying; after washing, drying and dyeing before heat setting, the fabric is subjected to antistatic treatment, drying, teasing, shearing. The interweaving of tights-charm is made with 5- and 7-needle.

The knitting of the upholstery knitted material is carried out on the warp knitting using warp knitting machines with 5- and 7-needle tights with parallel masonry at an air temperature of 23 _-4 ^{+3 o} C, relative humidity of 62 ± 5%.

The bound web is washed in four washers with mesh drums to remove oiling and extraneous applications. The water temperature in the baths is 5 ---> 50 ---> 40-45 ---> 20-25 ^o C, respectively. Web speed 13-20 m / min. Washing is carried out with the addition of hostapal SF in an amount of 1 g / l and trisodium phosphate 0.5-1.0 g / l.

After washing, the cloth is squeezed and fed to the drying chamber with a temperature of 120-125 ^o C.

The dried web is painted in dyeing autoclaves at a temperature of 140 ^o C and a pressure of 5 bar.

The painted web is washed to remove residual dye and chemicals at a temperature of 20-25 ^o C and the speed of the web 15-19 m / min.

 The canvas, washed and squeezed to a moisture content of 65-75%, is treated with an anti-static softener in order to give the canvas antistatic properties, a soft neck and ensuring high-quality bristling, squeezed to a moisture content of 75-85%.

The cloth is dried in chambers at a temperature of 100-115 ^o C.

Before teasing, the canvas is kept for 12 hours at a temperature of 22 _-4 ^{+3 o} C and a relative humidity of 62 ± 5%. Teasing is carried out in the course of knitting on pile machines at a web speed of 10-14 m / min.

 The pile fabric is trimmed to improve the uniformity of the pile covering to obtain a velor effect.

Shearing is carried out at a shaft temperature of 90-100 ^o and the speed of the blade 5-7 m / min, get a pile with a height of 1.5-2.0 mm

After teasing and shearing, the web is washed twice in clean water at a bath temperature of 50-60 and 20-25 ^o C and a web speed of 14-20 m / min.

Thermofixing is carried out at a temperature of 185-190 ^o C.

 Example 1

A knit fabric with a 5-needle charm weave with parallel masonry is knitted from brand A nylon multifilament yarns on a warp knitting machine at an air temperature of 26 ^o C, relative humidity of 57%.

The bound web is washed in four mesh drum washing machines. The water temperature in the baths, respectively, 50 ---> 50 ---> 45 ---> 25 ^o C, the speed of movement of the canvas 13 m / min. Washing is carried out with the addition of hostapal SF in an amount of 1 g / l and trisodium phosphate in an amount of 0.5 g / l.

The washed cloth is squeezed, then dried at a temperature of 120 ^o C, painted at a temperature of 140 ^o C and a pressure of 5 bar in a dye autoclave.

The painted web is washed at a temperature of 20 ^° C. and a web speed of 19 m / min.

The canvas, squeezed to a moisture content of 65-75%, is treated with an antistatic agent and squeezed to a moisture content of 75%, dried at a temperature of 100 ^o C.

The dried web is kept for 12 hours at a temperature of 25 ^o C and a relative humidity of 57%, then the web is teemed along the knitting at a web speed of 14 m / min, sheared at a temperature of 90 ^o C and a web speed of 5 m / min.

The pile cloth is washed twice in clean water with a temperature of 50 and 20 ^o C, respectively, and the speed of the cloth 14 m / min, heat setting is carried out at a temperature of 185 ^o C.

 A caproveille with a pile height of 1.5 mm is obtained having a uniform pile covering.

 Example 2

A knitted fabric with 7-needle charm weaving with parallel masonry is knitted from brand A nylon multifilament yarns on a warp knitting machine at a temperature of 19 ^o C, relative humidity of 67%.

The bound web is washed in four mesh drum washing machines. The water temperature in the baths, respectively, 50 ---> 50 ---> 40 ---> 20 ^o C, the speed of movement of the canvas 20 m / min. Washing is carried out with the addition of hostapal SF in an amount of 1 g / l and trisodium phosphate in an amount of 1.0 g / l.

The washed cloth is squeezed, then dried at a temperature of 125 ^o C, painted at a temperature of 140 ^o C and a pressure of 5 bar in a dyeing autoclave.

The painted web is washed at a temperature of 25 ^° C. and a web speed of 15 m / min.

Tightly pressed to a moisture content of 65-75% is treated with an antistatic agent and squeezed to a moisture content of 85%, dried at a temperature of 115 ^o C.

The dried web is kept for 12 hours at a temperature of 18 ^° C and a relative humidity of 67%, then the fabric is teased during knitting at a web speed of 10 m / min, sheared at a temperature of 100 ^° C and a web speed of 7 m / min.

The pile cloth is washed twice in clean water with a temperature of 60 ^o C and 25 ^o C, respectively, and the speed of movement of the cloth 20 m / min, heat-setting is carried out at a temperature of 190 ^o C.

 A caproveille is obtained with a pile height of 2 mm, having a uniform pile covering.

 The caploor made of brand A nylon multifilament yarns obtained by the proposed method has a pile height of 1.5-2 mm, uniform covering, its strength, wear resistance and practicality exceed the strength, wear resistance and practicality of velor made of wool yarn and leather, which makes the caprovel suitable for use as an upholstery material.
