Abstract

PP weft yarn replaces a method for jute weft weaving carpet, and step is as follows: 1) yarn pretreatment; 2) weave on Wilden carpet knitter; 3) carpet is obtained after gluing and thermal finalization process; The carpet obtained step 3) carries out lock seaming and can obtain finished product; In described step 1), alternative jute is cooked the raw material PP silk of the PP weft yarn of weft yarn, and its twist is 70 ~ 100 sth. made by twisting; Described step 2) in, measured Wilden carpet knitter, the PP weft yarn adopting step 1) to obtain carries out carpet weaving, technological requirement is: the scissors angle of adjustment PP weft yarn is to 348 ~ 353 degree, tension is increased to 9.5 ~ 11NM, namely on the tension basis of traditional jute weft yarn Wilden carpet, strengthen 1.5 ~ 3.5NM again, release angle is 298 ~ 305 degree; In described step 3), Wilden gluing machine carries out gluing and uses Steam Heating.

Description

The method of jute weft weaving carpet is replaced with PP weft yarn

Technical field

The invention belongs to textile technology field, specifically a kind of PP weft yarn replaces the method for jute weft weaving carpet.

Background technology

In prior art, common Wilden wall-to-wall carpet is all that jute is cooked weft yarn, and due to the operational characteristic of jute, under different temperatures, jute has different shrinkage degrees.So the carpet woven as weft yarn with jute, through often having a width to shrink after field of employment being laid, playing empty phenomenon and occurring, bringing very bad impact to the attractive in appearance of field of employment.

Summary of the invention

In order to solve by the problems referred to above that jute weft weaving carpet exists in prior art, the present invention proposes a kind of method that PP weft yarn replaces jute weft weaving carpet, and concrete steps are as follows:

1) yarn pretreatment; 2) weave on Wilden carpet knitter; 3) carpet is obtained after gluing and thermal finalization process;

In described step 1), alternative jute is cooked the raw material PP silk of the PP weft yarn of weft yarn, and its twist is 70 ~ 100 sth. made by twisting (preferably 80 twisting with the fingers); In processing procedure for PP silk, first add be twisted cylindrical after shape again, setting temperature at 90 ~ 100 DEG C, and will keep constant temperature 10 ~ 14 hours, is then cooled to normal temperature;

Described step 2) in, measured Wilden carpet knitter, the PP weft yarn adopting step 1) to obtain carries out carpet weaving, technological requirement is, the scissors angle of adjustment PP weft yarn is to 348 ~ 353 degree, tension is increased to 9.5 ~ 11NM(and namely on the tension basis of traditional jute weft yarn Wilden carpet, strengthens 1.5 ~ 3.5NM again), release angle is 298 ~ 305 degree;

In described step 3), Wilden gluing machine carries out gluing and by Steam Heating, gluing speed is 2 ~ 3 ms/min, setting process setting temperature be 120 ~ 140 DEG C; The drying time of stoving process is 13 ~ 16 minutes, and baking oven length is 7 ~ 9 meters.

The carpet obtained step 3) carries out lock seaming and can obtain finished product.

In described step 1), the twist is 80 sth. made by twisting; To keeping constant temperature 12 hours in the processing procedure of PP silk, then naturally cool to normal temperature.

Described step 2) in, the scissors angle of PP weft yarn is 350 degree, and 2 NM(and 10NM are strengthened on the tension basis of traditional jute weft yarn Wilden carpet again), release angle is 300 degree.

In described step 3), gluing speed is 2.5 ms/min, and the drying time of stoving process is 15 minutes, and baking oven length is 8 meters.

Compared with the carpet of existing jute weft yarn manufacture, have employed above-mentioned special parameter to adapt to the physicochemical properties requirement of PP weft yarn, the defect of the carpet obtained except jute weft yarn can be avoided to manufacture carpet, carpet back can also be made more smooth, pattern is more clear, smooth blanket back is conducive to the laying of carpet, and laying efficiency generally can be made to improve 30%, and also good than jute of laying carpet effect.Compared with prior art, the technical program utilizes PP weft yarn not absorb water, non-shrinking characteristic, by carrying out technique adjustment on existing carpet weaving equipment, PP weft yarn replaces jute to weave Wilden carpet, further, make the carpet obtained meet Product checking requirement, effectively solving the various of jute weft yarn carpet affects product quality phenomenon.

Accompanying drawing explanation

Fig. 1 is the process flow diagram of this method.

Detailed description of the invention

The technical program is further illustrated as follows below in conjunction with accompanying drawing 1 and detailed description of the invention:

PP weft yarn replaces a method for jute weft weaving carpet, and concrete steps are as follows:

1) yarn pretreatment; 2) weave on Wilden carpet knitter; 3) carpet is obtained after gluing and thermal finalization process; The carpet obtained step 3) carries out lock seaming and can obtain finished product.

In described step 1), alternative jute is cooked the raw material PP silk of the PP weft yarn of weft yarn, and its twist is 70 ~ 100 sth. made by twisting, and PP silk size can be determined as requested.Processing procedure for PP silk requires high, and first twisting must become cylindrical just to shape afterwards, and setting temperature will at 90 ~ 100 DEG C, and keep keeping 10 ~ 14 hours in insulating box, is cooled to normal temperature to use after outlet;

Described step 2) in, the scissors angle of PP weft yarn is 350 degree, and 2 NM are strengthened on the tension basis of traditional jute weft yarn Wilden carpet again, and release angle is 300 degree.

A series of adjustment in PP weft yarn production process, due to the characteristic that PP weft yarn is smooth, to a certain degree affects the start efficiency of loom, so will be carried out.First, the scissors angle of PP weft yarn, 350 degree are adjusted to by original 356 degree, tension strengthens 2NM(and 10NM), release angle adjusts to 300 degree by original 295 degree, by the adjustment of new technology, production efficiency than when producing jute weft yarn Wilden carpet taller 10%, and has effectively been stopped carpet door width and is shunk and play empty problem.
