Description

The production technology of fibrous water jet non-waven

Technical field

The production technology that the present invention relates to a kind of silk fiber and tencel fiber spunlace non-woven cloth, belongs to textile material technical field.

Background technology

At present, all to select hot-wind nonwoven cloth be raw material on the top layer of feminine hygiene protection pad.Along with growth in the living standard, female friend is also more and more higher to the requirement of quality of life, especially directly contacts the articles for daily use of some with human body, wherein just comprises panty liner.Because hot-wind nonwoven cloth rough surface, feel are partially hard, therefore comfortableness is poor.

Summary of the invention

The invention provides the production technology of the fibrous water jet non-waven of a kind of smooth surface, softness.

To achieve these goals, the technical solution adopted in the present invention is:

A kind of production technology of fibrous water jet non-waven, adopt silk fiber 50%(percentage by weight) and tencel fiber 50%(percentage by weight) be raw material, and enter successively shredding operation, combing operation, water and sting operation, hydrophilic treatment operation, baking operation, detect operation, coiling process online, divide cutting process.

As the further setting of such scheme, the cotton feeding box in described combing operation, adopts two-way feeding airstream vibration hopper, has solved the horizontal homogeneity question of product.

Feeding curtain in described combing operation, adopts the curtain of weighing to weigh and is feeding to cotton, solves the longitudinal grammes per square metre stability problem of straight paving.

Described combing operation adopts at a high speed mixed and disorderly carding machine carding to stablize the MD:CD ratio of product.

The main cylinder working roll of described combing operation is 100-120m/min, and main cylinder angle stripper is 130-140m/min, main cylinder rotating speed 700-800 m/min, and feeding grammes per square metre is 45 grams/㎡.

Described water thorn operation, its 5 water jet water thorn pressure are set as respectively: 25bar, 45bar, 65bar, 75bar, 40bar.

Described baking operation, its dryer temperature is controlled at 115-120 ℃.

Described hydrophilic treatment operation, is mainly carried out by high-pressure penetrating type finishing device; High-pressure penetrating type finishing device comprises the pulp storing barrel that connects successively by pipeline, strainer one, water tank, high-pressure micro-mist main frame, water inlet pipe with nozzle, and water inlet pipe is arranged in the water leg of upper end open; Also comprise the recovery tank, water pump, the coarse filtration machine that connect successively by pipeline; Wherein, recovery tank is connected with the lower end of water leg by pipeline, and coarse filtration machine is connected with water tank by pipeline.

The water leg of high-pressure penetrating type finishing device is arranged on the nonwoven fabric below between the water thorn spun-laced machine fabric guide roll of operation and the dryer fabric guide roll of baking operation, nozzle upwards faces toward the bottom of nonwoven fabric, high hydrophilizing agent in pulp storing barrel passes through nozzle, the form penetrating with high pressure sprays to nonwoven fabric, nonwoven fabric by the too high hydrophilizing agent of spray is sent in dryer and is carried out baking operation by dryer fabric guide roll, has effectively utilized online drying plant.

The high pressure that high-pressure penetrating type finishing device can carry out high hydrophilizing agent to the nonwoven fabric between spun-laced machine fabric guide roll and dryer fabric guide roll penetrates injection, effectively utilizes the drying function of Liao Xia road baking operation to dry online simultaneously.Therefore, apply after high-pressure penetrating type finishing device, the fibrous water jet non-waven produced through the present invention is just without finishing process, greatly shorten overall technological process, save production cost, reduced the discharge capacity of waste water and gas, the fibrous water jet non-waven feel of simultaneously producing is more soft, comfortable.The fibrous water jet non-waven that original production process is produced, need to carry out, after a series of finishing process, just becoming real finished product.Finishing process mainly comprises the steps such as debatching, dipping, fabric guide roll, oven dry, integrated artistic long flow path, and production cost is high, and produced simultaneously waste water, exhausted air quantity are also large.

Between described coarse filtration machine and water tank, be connected with strainer two.

On described water inlet pipe, be evenly provided with several nozzles.

Fibrous water jet non-waven of the present invention, take silk fiber and tencel fiber as raw material, and adopts water jet process to produce, and has replaced traditional hot-wind nonwoven cloth, and product surface is smooth, soft, comfortable, nontoxic, the use of applicable woman's sanitarg mapkin.

Below in conjunction with the drawings and specific embodiments, invention is described further.
