Precise Carding for Stable Yarn Quality｜Carding and Drawing Process at Changzhou Hengji Textile, a Key Step for Spinning Quality

A fine fabric starts with premium raw cotton, and relies on a sequence of rigorous spinning procedures. After proper storage and pre-opening, raw cotton moves to the carding and drawing workshop. Serving as a vital connecting stage in spinning, carding and drawing are responsible for fiber sorting, impurity removal and sliver levelling. The performance of this process directly determines the uniformity and cleanliness of finished yarn, making it an indispensable part of Hengji Textile’s full-range quality control system.

Inside the spinning workshop of Hengji Textile, carding units run steadily at a controlled pace. Pre-opened cotton material is fed continuously into the machines. Tangled cotton bundles are fully separated by the precise combing action of cylinders and flats, and crisscrossed fibers are gradually untangled. While carding, the equipment filters out fine dust and short fibres, minimizing neps and defects and preventing inherent flaws from passing to downstream processes. After carding, loose and disordered fibres are formed into continuous, even carded slivers, which are collected in sliver cans. Comparable to a purification and sorting station on the spinning line, thorough carding and effective impurity removal greatly influence yarn cleanliness and the smooth appearance of final fabrics.

The carded slivers are then transferred to the drawing frame. Multiple slivers with minor thickness variations are fed into the machine simultaneously. Through combination and drafting, these slivers are merged into one. Thickness fluctuations among individual slivers counterbalance each other during merging. Accurate drafting aligns fibre orientation inside the sliver and drastically reduces unevenness. The finished drawn slivers are stored neatly in cans, ready for the subsequent roving and spinning processes. Consistent and even slivers are essential to avoid yarn defects and prevent barring marks on finished fabrics.

In textile manufacturing, quality control must be implemented at earlier stages. Hengji Textile has established complete standardized protocols. Key parameters including carding gauge, delivery speed and drawing draft ratio are strictly monitored and recorded to stabilize sliver quality for every batch. Keeping pace with the intelligent transformation of the textile industry, the company keeps improving fundamental processes and carries out quality checks across every stage of spinning. Strict standards are upheld for this upstream process, with no compromise on details.

High-quality fabric cannot be achieved merely in the weaving stage. Quality is built step by step through successive processes. Raw material warehousing stabilizes cotton conditions, while carding and drawing secure uniform yarn structure. All procedures work closely as an integrated chain. Adhering to the philosophy of meticulous manufacturing, Hengji Textile refines its spinning workflow with stringent standards and delivers reliable semi-finished products to support the production of premium yarn and fabrics.

With years of dedication to the textile industry, Hengji Textile keeps optimizing production techniques and promoting workshop intelligent upgrading. Committed to dependable products that meet market and customer expectations, the company explores intelligent and eco-friendly transformation pathways for the textile sector while inheriting the craft of fine weaving.
