Double point bonded bushing production process

Production process for double point fusible interlinings

Warp-knitted fusible interlining is a type of interlining that uses warp-knitted fabric as the base fabric. It is made by coating with powder dot, paste dot or double dot. Warp-knitted fusible interlinings were first widely produced in Europe, where KUFNER, HANSEL, LAINIERE de PICARDIE and other famous European interliners produce a wide range of warp-knitted interlinings with advanced technology and quality.

The production process of warp-knitted fusible interlinings

Compared to woven interlining, especially cotton and polyester-cotton interlining, the production process of warp-knitted interlining is brief. The general production process is: warp-knitted blank - shrinkage (or pile) - dyeing - stentering and shaping - coating - inspection and packaging. The width of the product is generally divided into 90cm, 122cm and 150cm, the colour is mainly in this colour, bleached white, grey, women's interlining colour changes to more.

Classification of warp knitted fusible interlining

Warp knitting without weft lining

The warp knitted polyester filament yarn (single comb) is knitted without a weft lining, with a large weft stretch, the fabric surface is mostly netted and thin, mainly used for warp and weft fabrics with greater elasticity, such as Dupont's Lycra, the greater the range of activities of the garment parts and the bonding strength of the bonding lining does not require high garments, mostly using the microfine powder point method of coating the coating amount is relatively small.

Warp knitting full width lining weft lining

A kind of pile lining weft lining, lining weft yarn with viscose yarn, pile after the base cloth feel soft and plump because of the use of powder point coating elastic feel, easy to blister, heat shrinkage and shrinkage rate is difficult to control, fabric adaptability is not wide, has not been popular, but - - some soft feel pile double comb lining weft varieties with double point coating, to overcome the shortcomings of the powder point coating to expand the adaptability of the fabric, in many thick outerwear and uniforms or The other is polyester low stretch silk lining weft lining, general single comb section weave more, double comb, more comb section weave process to complex point variety is still less. Weft lining of low-stretch silk lining is currently the mainstream warp knitting bonded lining varieties, the use of a wide range. Using the powder point coating process is simple, low cost, but the elastic feel is poor; using the pulp point coating is mainly used for light texture, soft feel of women's clothing, as well as small parts of the clothing with lining and adhesion requirements are not high clothing; using the double point method of coating better results, adapt to a wider range, the better is the choice of thermosetting polyurethane (PUR) for the bottom slurry, the flour selection of copolyamide (PA) feel good It is better to use thermosetting polyurethane (PUR) as the base stock and PA as the top powder, which has a good feel and strong adhesion, dry-cleaning and washing resistance, and does not bleed through the glue.
