Description

A kind of shredded cloth and its manufacturing method

technical field

The invention relates to the field of functional fabrics, in particular to a tear-off fabric and a manufacturing method thereof.

Background technique

At present, the main material of electronic tape and trademark cloth is generally woven into base cloth-acetate cloth with acetate silk as the raw material, because acetate silk can be used as the base cloth to achieve the purpose of tearing by hand in the warp and weft direction, and it can be made by gluing and cutting Formed, so that the electronics industry and the trademark industry can speed up production. However, acetate fiber must rely on imports from the United States, Italy and other places, and the logistics cycle and cost are relatively high. Then, air-jet looms must be used for weaving, which will increase the weaving cost. The post-dyeing technology also relies on Korean dyeing technology. It can be made better, and the domestic dyeing technology has not been very stable.

In order to solve the above technical problems, a technical solution adopted by the present invention is to provide a hand-tear cloth, the warp yarn and weft yarn components of the hand-tear cloth are cationic modified polyester.

In a preferred embodiment of the present invention, the tear-off cloth is applied to electronic tape cloth or trademark cloth, and the tear strength test results of the tear-off cloth are as follows: the warp yarn is 3.5-5.8N, the weft yarn is It is 3.5~6N, and the test method is the national standard GB/T 3917.1-2009 impact pendulum method.

Provided is a method for manufacturing hand-torn cloth, comprising the steps of: using cationic modified polyester yarn as warp and weft to weave gray cloth, and the gray cloth is alternately treated with acid and alkali during refining and dyeing, and then soaped and shaped Get rags.

In a preferred embodiment of the present invention, a water jet loom can be used for weaving in the process of weaving gray cloth.

In a preferred embodiment of the present invention, the acid used in the acid treatment process is glacial acetic acid at a temperature of 100-130° C., and the amount of glacial acetic acid used is 5-10 g/L.

In a preferred embodiment of the present invention, the alkali used in the alkali treatment process is 36 Be liquid alkali and soda ash, the temperature is 100-130 ° C, and the consumption of the 36 Be liquid alkali is 10-30 grams per liter , the consumption of described soda ash is 10-30 gram/liter.

In a preferred embodiment of the present invention, the acid-base alternating treatment process is carried out in an open-width dyeing machine.

In a preferred embodiment of the present invention, halogen-free dyes, glacial acetic acid and leveling agent are used in the dyeing process.

The beneficial effect of the present invention is: the hand-tear cloth of the present invention and manufacturing method thereof, the hand-tear cloth obtained can be used as electronic tape cloth or trademark cloth, and its tear strength test result is: warp yarn is 3.5～5.8N, The weft yarn is 3.5~6N. The test method is the national standard GB/T 3917.1-2009 impact pendulum method. The style of the cloth surface remains basically unchanged before and after treatment. This manufacturing method uses common raw materials that are easily available in China, and the cost is reduced. The production cycle is shortened, the efficiency is improved, and the production difficulty is reduced after the weaving process is changed from air jet to water jet.

Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Provided is a hand-tear cloth, the warp yarn and weft yarn components of the hand-tear cloth are cationic modified polyester.

The manufacture method of described tear cloth, comprises the steps as:

Cationic modified polyester yarn→gray cloth→refining→acid treatment→alkali treatment→dyeing→hand tear cloth.

(1) The present invention adopts the domestic common raw material—cation-modified polyester fiber to make hand-tear cloth. Firstly, cationic-modified polyester yarn is used as warp and weft to weave gray fabrics of various specifications. The specifications are based on electronic tape or trademark cloth. These are specified for different purposes.

(2) After refining and dyeing, the gray cloth is alternately treated with acid and alkali in a high-temperature and high-pressure open-width dyeing machine to make it strong and brittle.

The beneficial effects of the present invention are:

1. The tear strength after brittle treatment is basically the same as that of the traditional acetate cloth, and the cloth style such as the weight and surface texture before and after treatment is also basically unchanged;

2. The torn cloth can replace acetate cloth in the electronic tape industry and trademark cloth industry;

3. The raw material import of hand tear cloth is changed to domestic, acetate fiber is changed to cationic fiber, the raw material cost is 1/4 of the original, the production cycle is shortened (three months to 20 days), and the efficiency is improved;

4. The weaving process is changed from air jet to water jet, which reduces production difficulty and weaving cost.

The above descriptions are only examples of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process conversion made by using the content of the description of the present invention, or directly or indirectly used in other related technical fields, shall be The same reasoning is included in the patent protection scope of the present invention.
