Embodiment 1

[0039] Embodiment 1: get 5Kg cowhide two-layer leather leftovers, defibrate, comb through carding machine and lay the net, the grammage of net is 100 grams / square meter; Lave net through air flow, the grammage of net is 200 grams / square meter; A good net is pre-wetted with a pressure of 2 MPa for 2 seconds, pre-stabbed with a pressure of 30 MPa for 3 seconds, and then stabbed in the front and back with a high-pressure water flow at a temperature of 35 ° C and a pressure of 200 MPa; Press dry to a water content of 35% with a 1-ton oil pressure dryer, then tie-dye with microwave dyeing technology, and then dry with 32 sets of drying cylinders in a circular heating method. The drying temperature is 35°C and the drying time is 12 minutes; After the obtained kraft fiber base cloth satisfies the basic performance of the American standard fabric, the obtained base cloth is trimmed and packaged.

Embodiment 2

[0040] Embodiment 2: get 15Kg cowhide two-layer leather leftovers, defibrate, comb through carding machine and lay the net, the grammage of net is 120 grams / square meter; Lave net through air flow, the grammage of net is 300 grams / square meter; A good net is pre-wetted with a pressure of 4MPa for 4 seconds, pre-stabbed with a pressure of 50MPa for 2 seconds, and then stabbed in the front and back with a high-pressure water flow at a temperature of 20°C and a pressure of 300MPa; Press dry to a water content of 45% with a 1-ton oil pressure dryer, then tie-dye with microwave dyeing technology, and then dry with 32 sets of drying cylinders in a cyclical heating method. The drying temperature is 70°C and the drying time is 6 minutes; After the obtained kraft fiber base cloth satisfies the basic performance of the American standard fabric, the obtained base cloth is trimmed and packaged.

Embodiment 3

[0041] Embodiment 3: get 20Kg cowhide two-layer leather leftovers, defibrate, comb through carding machine and lay the net, the grammage of net is 150 grams per square meter; Lave net through airflow, the grammage of net is 350 grams per square metre; A good net is pre-wetted with a pressure of 6MPa for 5 seconds, pre-stabbed with a pressure of 80MPa for 1 second, and then stabbed front and back with a high-pressure water flow at a temperature of 45°C and a pressure of 250MPa; Press dry to a water content of 55% with a 1-ton oil pressure dryer, then tie-dye with microwave dyeing technology, and then dry with 32 sets of drying drums in a circular heating method. The drying temperature is 100°C and the drying time is 8 minutes; After the obtained kraft fiber base cloth satisfies the basic performance of the American standard fabric, the obtained base cloth is trimmed and packaged.

Abstract

The invention belongs to the field of cowhide materials, and particularly relates to a method for producing a cowhide fiber base fabric. The cowhide fiber base fabric is made of cowhide fibers by means of nonwoven technology and by performing fine combing lapping, airflow lapping, spunlace pre-needling, needling reinforcement, pressing, dyeing, drying, trimming and packaging after uncoiling leftover cowhide. The cowhide fiber base fabric is breathable, moisture-absorbent and comfortable, has all properties of natural fibers including fluffiness, resilience, flame resistance, softness, no abnormal odor and the like, can be made into genuine leather products including garments, cases, sofas, shoes and the like, and is an effective substitute product for genuine leather. Raw materials of the cowhide fiber base fabric are the leftover cowhide and discarded cowhide, production cost is saved, and environmental pollution is reduced.

Description

technical field [0001] The invention belongs to the field of cowhide materials, and in particular relates to a production method of a cowhide fiber base cloth. Background technique [0002] In recent years, with the increasingly severe global ecological problems such as resources and environment, my country's leather industry is facing the severe challenge of the "sustainable development" strategy. my country is a big country in the leather industry. The traditional leather industry has caused a large loss of animal resources. The solid waste generated by cutting and tailoring after tanning accounts for about 30%. my country produces more than 1.4 million tons of such leather waste every year. If If these solid wastes cannot be treated reasonably, on the one hand, it will seriously pollute the environment, and on the other hand, it will also cause a large loss of collagen fibers. Therefore, the reuse of leather waste has become one of the important topics that domestic and f...
