2. The twisting process of high twist coating is reasonable in arrangement: when the twist is lower than 1200 twists/meter, naked ammonia (namely spandex is exposed/white) can occur, which will affect the printing and dyeing quality of the subsequent fabric; when the twist is higher than 1500 twists per meter, the hand feeling of the coating weft is difficult to shape due to roughness, the stability of the twist is influenced, and the controllability of the subsequent weaving quality is influenced, for example, the weft shrinkage phenomenon is serious, the rebound resilience of the fabric is uneven due to the weft shrinkage, and the skin-friendly feeling of the woven fabric is influenced.
3. Primary shaping purpose: can eliminate weaving wrinkle marks, and can ensure that the subsequent degumming of the fabric is slow and uniform and the elasticity of the fabric is uniform.
4. The pretreatment purpose is as follows: fully swelling mulberry silk warp in the fabric and eliminating the internal stress of coating weft in the fabric.
5. The degumming process has the advantages of two-step degumming, mild technological conditions, slow degumming speed, uniform degumming and prolonged degumming time, ensures uniform resilience of the fabric in the degumming process, and prevents wrinkling of the fabric due to nonuniform degumming.
6. Optimizing a composite sizing process: when in compound shaping, the melting of the chinlon can cause the hand feeling to be hard, and the mulberry silk warp is easy to yellow, so that the compound shaping adopts an overfeeding mode combined with the temperature (namely 160 ℃) lower than the conventional 180-185 ℃, and adopts the spandex capable of being shaped at low temperature in a matching way to avoid the adverse factors, thereby ensuring the normal elasticity of the spandex and leading the fabric to reach the elasticity required by the process.
