Related performance and quality of woven resin interlinings without coating from China manufacturer
Woven resin interlinings without coating from China manufacturer The reason why it is called resin interlining is because the resin is used to increase the hand feeling (hardness) and elasticity of the product, so the hand feeling, shrinkage and formaldehyde content of the resin interlining directly affect the performance and quality of the resin interlining. Quality, then we will start from these aspects to discuss:
1. The feel and elasticity of woven resin interlinings without coating from China manufacturer
Resin linings for different purposes have different requirements for relative feel and elasticity. Resin linings usually have three kinds of feel: soft (S), medium (M) and hard (H). The elasticity requirements for each feel must be very good, and To have durability and retention, even when the ambient temperature and humidity change or the interlining is washed, the hand feel and elasticity will not change greatly.
2. Dimensional change of resin lining after washing
Woven resin interlinings without coating from China manufacturer The dimensional change after washing is mainly caused by the wetting expansion and relaxation shrinkage of fibers and fabrics when the interlining is washed.
3. Breaking strength
Breaking strength is another important indicator of resin interlining, and it is a technical difficulty in production, because the hand feeling and breaking strength of the interlining are a pair of contradictions, the harder the hand feeling of the interlining, the more the breaking strength will be reduced, the hand feeling is too hard, and the amount of resin is too large , often causes embrittlement of the interlining.
4. Chlorine yellowing
Chlorine absorption and yellowing are the main disadvantages of resin interlinings, which often have adverse effects on fabrics, because the resin finishing agents used to produce resin interlinings generally contain N-methylolamide.
5. Free formaldehyde content of woven resin interlinings without coating from China manufacturer
General resin interlinings have the problem of formaldehyde pollution. With the continuous improvement of clothing hygiene requirements, the control of formaldehyde content in textiles is becoming more and more stringent in various countries.
6. Requirements for color fastness of resin lining
Woven resin interlinings without coating from China manufacturer should also have good air permeability; can be cut forward, that is, the blade will not be stained when cutting; good sewing performance, can be sewed freely on the sewing machine, etc.
