T2 could indicate the interaction between water molecules and biomass [1-2], 1-10ms for the bound water, free water for more than 10ms, and 2.2s for the distilled water [3].
Results and discussion Fig1 FTIR spectra of untreated (a) and esterified (b) wood From figure 1, the original 2924 cm-1, 1423 cm-1, 1372 cm-1, 898 cm-1 absorption peaks were all the characteristic peaks of the cellulose[14]. 3342cm-1 was lignin’s OH stretching vibration, and 1734 cm-1, 1591 cm -1,1506 cm-1 were the C = O absorption peaks of hemicellulose and lignin [15].

The chemical compositions of the three alloys are shown in Table 1.
Table 1 Chemical compositions of the investigated alloys.
As previously reported by the present author[1], three exothermic peaks responsible for the formation of cluster(2), β” and β’ were observed about 343, 533 and 573K, on the other hand another exothermic peak at ~323K responsible for the formation of cluster(1) disappears because cluster(1) was already formed during natural aging for 1.8ks.
Conclusions 1.

At present, the sum of the recovery angle in the warp and across warp is commonly seen as the index of the WFEWR. 1.2 The Problem and Improvement Program 1.2.1 Manual Cutting’s Objective Error.
The experimental fabrics’ specification is shown as the Table 1.
The 1#, 2# samples are made from the same machine with the same organization on both sides, among which the 1# is plain woven and 2# is 4/4 twill woven.
