Garment Interlining Selection-How To Choose Knitted Lining

Jan 21, 2018

Garment interlining Development Today, from the 1th generation of cotton, hemp, brown and other fabric lining and 2nd generation of black carbon lining (wool lining, Mawei liner), the 3rd generation of resin lining developed into the modern apparel industry in the field of the 4th generation (spinning and Non-woven) Hot melt adhesive liner, and high flexible, ultra-thin, environmental protection, health-type, washable, Breathable Advanced Interlining as the 5th generation of new bonded interlining also emerged.

Knitted lining, is knitted cloth as the base cloth, after hot melt adhesive coating processing of bonded interlining. Knitted lining and weft-lined lining, warp-lined and weft-lined warp-lined, its performance similar to woven lining, both good with the movement, but also a good drape.

The knitted lining, which is an adhesive liner and is a permanent type of adhesive liner, is an important part of the 4th generation interlining (non-woven and bonded) and 5th generation Interlining (modified adhesive liner). Due to the characteristics of knitted fabrics, knitted lining becomes with the general adhesive lining different, unique knitted fabric special interlining, mainly used for knitted coat of the predecessor, collar, door lapel, cuffs, hem and bag mouth as well as hakama waist, panties mouth (zipper fixed parts), foot (hem) and other parts, to do local adhesion, played to the reinforcement, protection, Modelling and other functions.

Types of knitted lining

The adhesive liner "with the sticky seam" simplifies the modern garment processing technology, so that the efficiency of industrial production is unprecedentedly improved. Knitted lining as a kind of adhesive lining, it not only gives a good shape of clothing, but also to make clothing more light, thin, soft, very, elastic, Shu, endowed with the colorful aesthetic characteristics of clothing, just right to reflect people's personality requirements for modern clothing style.

The knitted lining can be divided into different kinds according to different dividing ways. According to the formation of knitted lining cloth can be divided into: warp-lined, weft-lined, non-woven plus seam lining. According to the performance of knitted lining fabric can be divided into: high elastic lining, low elastic lining, four-direction elastic lining, high-support high mesh lining. According to the use of knitted lining can be divided into: large body lining, collar lining, door lining, hem lining, cuffs lining, pocket lining, waist lining, panties mouth lining, such as drawing lining.

Selection of knitted lining

Knitted apparel, especially knitted garments, have many differences from those used in woven fabrics. The most characteristic of knitted fabrics used in knitted garments is multi-directional elongation. Because whether the use of natural fiber fabric or chemical fiber fabric or other interwoven fabrics, due to the coil series, knitted fabric is very obvious scalability. Therefore, the choice and use of knitted fabrics with this feature similar or the same adhesive lining, become knitted garments (clothing) the preferred condition.

However, the use of knitted fabrics with the same telescopic characteristics of interlining, not only to consider the stability of knitted fabrics after bonding, and for the design of the needs of modelling, it must be fixed and reinforced, but also require a flexible knitting fabric with different structure of the relatively stable knitted lining, thus controlling the activities of its fabrics. For example: the collar and cuffs of a loose knit suit, to use an easily retractable woven or Non-woven fusible interlining for better results. According to the design purpose of knitted garments and the characteristics of clothing fabrics, it is a key to choose the knitting lining differently. The selected adhesive lining is different, then the performance of the knitted fabric after bonding is not the same. The selection should carefully consider these changes, make careful choice. Therefore, the use of knitted lining must be clearly understood in the case of knitted fabric and knitted coat characteristics, select the appropriate (correct) interlining.

Knitted lining corresponds to the characteristics of knitted fabrics and knitted garments, should have the performance and quality to meet the needs of knitted apparel, can have a wide range of application adaptability. Its intrinsic quality requirements are as follows: with the dynamic (telescopic), full of elasticity, strong fastness, anti-loose, roll edge, breathable, hygroscopic, soft, not easy to peel, good sewing, not easy to deformation after washing. In addition, should also have anti-static, antibacterial, low formaldehyde, health and other properties.

Select the adhesive liner must be paid attention to: to obtain adequate adhesion, no surface hot melt adhesive leakage, set accurate bonding conditions, interlining and fabric to match.

It is necessary to use adhesive liner to do the following rigorous testing, including: Peel strength, adhesive leakage, feel good or bad, fabric shrinkage, fabric appearance quality changes (foaming, yellowing, etc.), dry cleaning, washing, etc.

According to these projects on the use of fabrics to do adhesion test, the correct selection of adhesive lining, to determine the adhesion requirements of the sticky hot conditions, in order to achieve the best matching with the fabric requirements.

Select Considerations

The process of each garment is not the same, even if the same garment products, the processing of various garment processing enterprises are different. Therefore, the processing of knitted lining of the enterprises and the performance of the adhesive equipment will be different.

Before the primary bonding liner, we must first confirm the 4 conditions of the garment (fabric shrinkage, pressing temperature, time and pressure, etc.), then you can preselection the bonding lining, set the bonding conditions, through testing to demonstrate the correctness of its choice. The main test demonstration is as follows: Confirm the fabric, fibrous tissue which conforms to the clothing design requirements, set the bonding temperature (such as natural fiber is 160 ℃, synthetic fibre is 140 ℃); According to the Fabric organization pressure (for example, the woven fabric is 0.3kg/cm2 and the knitted fabric is 0.2kg/cm2) , according to the fabric quality, thickness to determine the adhesive lining, set the pressure of the time (refer to the Adhesive liner processing plant specified fabric quality, thickness limit selected interlining, set to conform to the standard adhesion of the adhesive lining pressure hot conditions).

Before doing the bonding test, set the bonding time and conditions by referring to the setting temperature, setting pressure and the standard of test lining. It is assumed that the bonding pressure and hot conditions, test: adhesion, adhesive leakage, feel changes, fabric shrinkage, fabric appearance changes (discoloration, hair, prints, hot light, etc.). In these test projects, when abnormal conditions occur, the need to change the adhesion or adhesion conditions, the adhesion test again.

Adhesion test results are normal, mainly verify the intermediate and finished product pressure hot situation: adhesive leakage, reverse leakage. When an exception is made, the related test is repeated.

Also need to do in line with clothing design requirements of the washing test, testing: adhesion, adhesive leakage, feel, shrinkage and so on. When the result is abnormal, the content of the shrinkage item is tested again.

If there is no problem with the test results, the final adhesion, adhesion and adhesion conditions can be determined.

Enterprises to the knitting lining before processing, also need to the lining of the variety of specifications, quality performance, the main indicators (such as shrinkage, peel strength, wrinkle recovery, etc.) as well as the types and characteristics of the substrate, hot melt adhesives category and characteristics, pressing conditions and pressing methods, etc. have a certain degree of understanding and understanding.

Before the process is determined, relevant technical personnel to be consistent with mass production of bonded pressing conditions and methods of adhesion test, determination of adhesion peel strength, size changes, appearance changes and feel, and so on, until qualified (if not meet the needs, the need to continue to adjust the pressure-hot conditions to determine).

Garment processing has a central ironing and final finished product ironing. If necessary, in order to further confirm the reliability of the interlining adhesion effect, can be carried out in line with the actual clothing ironing uniform ironing test to prevent abnormal phenomenon.

The above several aspects of work completed, where passed (qualified) testing, you can determine the required interlining varieties specifications, set a scientific and reasonable way and conditions of pressing, to provide clothing for mass production of the required standard parameters.
