Description

A production process of medium-thick encrypted printing interlining

technical field

The invention relates to the technical field of interlining production, in particular to a production process for medium-thick encrypted printed interlining.

Background technique

Polyester low elastic yarn is used as the base fabric after weaving and other treatments. Because of its soft hand feeling, good elasticity in the weft direction, short production process, rich variety and adapting to the requirements of modern clothing for soft, elastic, light and thin interlinings, it has recently become more and more popular. It is more popular with fashion designers and manufacturers. The cloth that has not been printed and dyed after weaving is called gray cloth. After the gray cloth is processed, the base fabric is obtained, and the base fabric is double-point coated to form the interlining through pretreatment and other processes. The warp and weft density of the woven interlining is the two main indicators. The yarn in the length direction of the fabric and auxiliary materials is called warp yarn. The yarns in the width direction of fabrics and accessories are called weft yarns. In the process of garment production, interlinings are indispensable accessories, especially in autumn and winter. Interlinings are commonly used accessories. Sewing and shaping clothing parts are tall and straight. Medium-thick interlining is widely used in the production of suits. The texture and shape of interlining are directly related to the shape of suits and other clothing. At present, the density of medium-thick interlining is low, which affects the interlining. The texture, and the style is single, lacking in aesthetic feeling, which reduces the wearability and aesthetic feeling of the medium-thick interlining. Therefore, it is necessary to propose a production process for the medium-thick encrypted printed interlining.

Elasticity, neat fabric width, padding softener at the same time, the padding temperature is 175°C, and a medium-thick base fabric with a shaped cloth width of 121-125cm is prepared;

Step 4. Rotary screen printing. The base fabric processed in step 3 is printed on a horizontal rotary screen printing machine through a seamless cylindrical screen. The printed pattern is made by photosensitive method, and the color is separated by manual drawing and computer Printing and plate-making process is carried out in a combined way. The printing color paste adopts reactive dyes. When printing, the color paste is fed from the scraper holder tube inside the nickel screen through the automatic pulping machine, and is adjusted by the liquid level controller to make the amount of color paste during the printing process Keep it constant and draw the required fine patterns. The specifications of the seamless nickel cylinder mesh are 80, the mesh diameter is 0.1mm, and the thickness is 0.08mm. The base fabric with patterns printed on one side can be obtained. The printed pattern can be pattern patterns or geometric patterns;

Step 5, double-point coating, perform double-point coating process on the non-printed side of the base fabric after step 4 on the paste point machine, and apply polyamide PA and polyester PES hot melt adhesive by means of paste point dusting , add water and additives to polyamide PA to make a slurry, apply the polyamide PA slurry evenly on the base fabric through the rotary screen equipment of the slurry point machine, and then apply the powdered polyester PES hot melt adhesive through the powder spreading device Sprinkle evenly on the polyamide PA coating, recover the excess unadhered polyester PES hot melt adhesive on the base cloth by the powder suction device, and then perform a preheating treatment at 95°C for 3 minutes, and then carry out 170°C for 3 minutes It is baked and melted for 5 minutes, and cooled to form. The speed of the slurry dispenser is 35m/min, and the dispensing pressure is 1.5-2.5kg/cm2;

Step 6: Check the coiling. After passing the test, pack the products that are qualified in quality and pattern to form a finished medium-thick encrypted printed interlining.

Beneficial effects of the present invention: Compared with the prior art, the production process of a medium-thick dense printed interlining provided by the present invention increases the weft density of the gray cloth by 30-40% through water spray densification treatment, and water spray densification is more effective than air jet densification. The densification has a greater traction force on the polyester low-elasticity yarn, which makes the interlining structure more compact and wears less on the yarn, which solves the current situation of low density of the medium-thick interlining and improves the strength and flexibility of the interlining at the same time. The texture of the medium-thick interlining is improved, and the interlining is printed through the rotary screen printing process, and the liquid level controller is used to adjust it to keep the amount of color paste constant during the printing process to ensure the consistency of the printed pattern. The printing color paste uses reactive dyes Guarantee the durability of the printed pattern, and there are many printing styles, beautiful and generous, which improves the current situation of single style and lack of aesthetic feeling of the medium-thick interlining, makes the interlining have higher ornamental value, and improves the wearability of the medium-thick interlining At the same time, the economic benefit of medium-thick interlining is increased.
