最近6~7年来,我国西部地区缫丝产能迅猛扩张,产业链内部平衡被打破,形成了13万吨的缫丝能力去抢夺只有8万吨不到的丝纤维原料(64万吨鲜茧)。由于西部地区饲育要素相对富足宽松,蚕农扩量增批的同时,缺少质价挂钩机制,也就放松了对质量的重视。伴随着东部优质茧丝产量减少,西部中低端茧丝增长迅速。
In the recent 6 ~ 7 years, the silk reeling capacity in the western region of our country expanded rapidly and the internal balance of the industrial chain was broken down, forming 130,000 tons of reeling capacity to seize the silk fiber raw material (less than 80,000 tons) . Due to the relative abundance of easing factors in the western part of the country, the quotas of silkworm farmers have been increased. At the same time, the lack of quality-linked mechanism has also loosened the emphasis on quality. Accompanying the reduction in the production of high-quality cocoon yarn in the east, the cocoon yarn in the middle and low end of the west grew rapidly.
